During compressor shutdown, gravity, thermal action and
refrigerant absorption can result in a refrigerant and oil mixture
in compressor crankcase. Gravity flow can be prevented by the
use of recommended loops, but thermal action and the absorp-
tion of refrigerant by lubricating oil cannot be prevented by
piping design.
protection against liquid refrigerant accumulating in the
compressor crankcase.
Do not use pumpdown control with dry expansion coolers
as it may cause frost pinching or freeze-up. Do not use
pumpdown control with dry expansion coolers if it is antici-
pated that there will be short bursts of system operation, as this
will result in a gradual loss of oil.
For the above reasons, the compressor must be controlled
during idle times by one of the following methods.
MINIMUM PROTECTION — The minimum protection that
Carrier will allow is shown in Fig. 1. Actuated control thermo-
stat energizes crankcase heater and closes the liquid line
solenoid valve simultaneously. With crankcase heaters
energized, the crankcase temperature is always held above
shutdown temperature in the evaporator coil and there will be
no refrigerant migration to the crankcase.

The control relay coil is located in parallel with the liquid
line solenoid, and a normally open control relay contact is
added in series with the compressor starter and other auxiliary
safety devices.
Fig. 2 — Automatic Pumpdown Control
When the thermostat calls for cooling, the solenoid valve
opens and control relay is energized. This closes the relay
contact and, if other safety devices are in their normal position,
compressor will start. Simultaneously, the normally closed
compressor auxiliary contact will open, removing crankcase
heaters from the circuit.
SINGLE PUMPOUT CONTROL (Fig. 3) — Pumpout con-
trol is not as effective as pumpdown control in keeping liquid
refrigerant out of the crankcase. However, it is usually satisfac-
tory when used with crankcase heaters if pumpdown is not
acceptable.
Single pumpout control is similar to pumpdown control,
except that a pumpout relay is added, a normally open com-
pressor auxiliary contact is necessary, and energizing of crank-
case heaters is required at end of each operating cycle.
When the thermostat is satisfied, the solenoid will close and
control relay is deenergized. This opens relay contacts and
compressor stops. This causes compressor auxiliary contacts to
close, energizing crankcase heaters.
Specifications are sometimes written to call for a degree of
protection greater than that afforded by the standard method. If
this is the case, either single pumpout or automatic pumpdown
control may be required.

With single pumpout control, when the thermostat is satis-
fied, the compressor pumps down once and stops. It starts
again only when the thermostat calls for cooling. In pumpdown
control, the compressor cycles only on the low-pressure switch,
regardless of thermostat demands.
Do not use pumpout control with dry expansion coolers as it
may cause frost pinching or freeze-up.
MANUAL PUMPDOWN — The compressor may be con-
trolled manually without the use of pumpdown, or single
pumpout control, and without crankcase heaters, provided the
system is at all times under control of a qualified operator. The
operator will pump down the system by use of manual valves
and will keep liquid, suction and discharge valves closed when
the machine is not operating.
Fig. 1 — Minimum Protection
AUTOMATIC PUMPDOWN CONTROL (Fig. 2) — Pump-
down control is the most effective means of compressor control
in keeping liquid refrigerant out of the crankcase on system
shutdown.
In the basic pumpdown control sequence, the thermostat
controls the liquid line solenoid valve to stop or start the flow
of refrigerant to the evaporator as required.
The pumpdown control system permits compressor cycling
if a system malfunction allows low side pressure to rise.
Although this cycling is sometimes considered objectionable, it
illustrates need for maintenance attention and provides positive

When operating conditions are such that suction gas
becomes highly superheated and/or the compression ratio is
high, it is recommended that an oil cooler be used on the com-
pressor. An oil cooler is required on increased displacement
compressors (5H46, 66, 86, and 126) on installations where
compressor(s) can be subjected to extended periods of continu-
ous, fully unloaded operation. These periods do not afford
sufficient removal of compression and friction heat, and could
result in overheating of the running gear, shaft seal and crank-
case oil. The addition of an oil cooler removes excessive
heat, ensuring increased life expectancy of compressor and
components.
Extended periods of continuous, fully unloaded operation
will occur usually on variable-volume installations that use hot
gas bypass to maintain conditions under all load situations.
Without hot gas bypass, the compressor will usually cycle on
the low-pressure switch (or temperature controlling device)
giving time for seal, oil and crankcase to cool.
Compressor Capacity Notes
1. Compressor capacities are based on 1750 rpm and 15 F
subcooling for all unit sizes and refrigerants.
2. Multiplying factors for other rpm:
RPM
1450
1160
0.674
0.602
Capacity
Bhp
0.835
0.798
See Multiplying Factors chart on page 31.
3. Liquid subcooling greater than (less than) 15 F incorpo-
rated in ratings increases (decreases) system capacity by
1/2 of 1% for each degree of subcooling. When correcting
for subcooling, brake horsepower does not change.
4. Refrigerant temperatures shown in Table 5 are saturation
temperatures corresponding to pressures indicated at
compressor. Actual gas temperatures are higher because
of superheat.
On multiple-compressor installations where all units are
manifolded into one refrigerant circuit, the controls should be
designed to cycle off compressors at light loads to put maxi-
mum output on the still operative compressor. It is always
desirable for the compressor to operate with as many cylinders
as possible in loaded condition.
Water-cooled oil cooler package is available from the
factory and is easily field installed on all 5 Series compressors.
Refer to 5F,H Compressor Ratings to determine when oil
coolers are required. These ratings, however, do not indicate oil
cooler requirements during periods of extended continuous
operation under fully unloaded operation. This should be
determined on individual job basis.
5. Capacities are based on actual suction gas tempera-
tures to compressor of 65 F for R-12, R-134a, R-502,
and R-507/404A. (This assumes superheat is obtained
from liquid suction interchanger or in evaporator.)
Capacity corrections, other than for rated suction gas
temperatures, may be obtained by using Rating Basis and
Capacity Multipliers Tables 6 and 7. Refrigerant-22
suction gas superheat for ratings (15 F) normally occurs
because of expansion valve operation and line losses.
Therefore, R-22 ratings can be used without adjustment.
An alternate method for capacity correction is to run the
Carlyle Selection program to obtain performance ratings
at other than 65 F return gas temperature.
Water flow through compressor heads (and water-cooled oil
coolers, if used) must be shut off when the compressor is not
running to prevent refrigerant vapors from condensing at the
compressor during OFF cycles. For this purpose a solenoid
valve is recommended in the water supply line to compressor
heads.
Values listed in Table 13 assume a water temperature rise of
30 degrees. Oil cooler and water-cooled heads must be piped in
series, with the oil cooler first. Leaving water temperature
should be between 100 F and 120 F, with 120 F being maxi-
mum allowable temperature. Maximum working pressure for
water-cooled heads is 125 psi.
Compressor ratings and capacities are included in
Tables 8-12.
Compressor Features and Accessories
WATER-COOLED HEADS AND OIL COOLERS — Water
cooled heads are typically not necessary for R-12 or R-134a
applications within the range of compressor ratings shown in
this publication. For R-502, or R-507/404A at the shaded con-
ditions shown in the compressor ratings tables, water-cooled
heads may be necessary, if the discharge temperature is greater
than 275 F. The discharge temperature will increase with return
gas temperature.

NOTES:
1.
Shaded ratings require an oil cooler when using a liquid-
suction interchanger, or when 50 degrees of superheat is
exceeded.
2. An oil cooler is recommended for all long stroke compressors
(5H46,66,86 and 126).
3. Refer to Table 5 for Total Heat Rejection.

NOTES:
1.
Shaded ratings require an oil cooler when using a liquid-
suction interchanger, or when 50 degrees of superheat is
exceeded.
2. An oil cooler is recommended for all long stroke compressors
(5H46,66,86 and 126).
3. Refer to Table 5 for Total Heat Rejection.

NOTES:
1.
Shaded ratings require water-cooled heads, if the dis-
charge temperature exceeds 275 F.
2. An oil cooler is recommended for all long stroke compressors
(5H46,66,86 and 126).
3. An oil cooler is required when SST is below –20 F.

1.
Shaded ratings require water-cooled heads, if the dis-
charge temperature exceeds 275 F.
2. An oil cooler is recommended for all long stroke compressors
(5H46,66,86 and 126).
3. An oil cooler is required when SST is below –20 F.

Vibration isolators giving approximately /8-in. deflection
are available for superior isolation or if the compressor is run at
slower speeds. Tables 14 and 15 provide an estimated weight
distribution on legs of a compressor or condensing unit when

MUFFLERS — Four standard mufflers cover the entire model
range of 5F,H compressors. It is recommended that these
mufflers be installed when compressors are used with remotely
located water-cooled or evaporative condensers.

SAFETY RELIEF VALVES — All 5H compressors are
equipped with built-in safety relief valves that are factory set to
relieve from discharge to suction side of the compressor at a
pressure differential of 350 psi.
Mufflers are not usually necessary with smaller 5F
compressors and their use is recommended only when quiet
operation is required.
Safety relief valves that relieve at a 400 psi pressure differ-
ential are factory installed on the 5F60 compressor but are not
available with smaller 5F compressors.
SUCTION STRAINERS — Each 5F,H compressor is
equipped with one or 2 suction strainers located in the suction
manifold. On new installations, felt filters should be used in
suction strainers to trap foreign material left after installation.
After 50 hours of use, these felt filters must be removed. See
5F,H Installation Instructions for further details.
Each piping package to convert 5H compressor units to
condensing units includes a standard muffler of appropriate
size.

Pressure drop through mufflers is about /2 psi at 40 F
suction and 105 F discharge with following loadings: 5 tons
with 5F20 muffler, 15 tons with 5F40 muffler, 35 tons with
5H40 muffler and 100 tons with 5H120 muffler.
Table 14 — Weight Distribution, Condensing Units
OIL SAFETY SWITCH — An oil safety switch is provided
as standard with all compressors except 5F20 and 5F30. This
switch is optional equipment on 5F20 and 5F30 compressors.
This switch will shut off the compressor before high oil
temperatures or lack of oil causes loss of oil pressure which can
result in compressor failure. As a safety feature, this switch
must be reset manually after cutout.
OIL SEPARATORS — Oil separators in the hot gas discharge
line are not recommended for general use. However, there are
systems where protection afforded by a separator is desirable,
notably systems employing flooded evaporators or refrigera-
tion systems with long system piping. For a more complete
discussion see Carrier’s System Design Manual.

CRANKCASE OIL HEATERS — Crankcase oil heaters are
available for all 5F,H compressors. Heaters keep the crankcase
warm during off cycles and thus minimize refrigerant absorp-
tion in the oil. Crankcase heaters are recommended for CFC or
HCFC refrigerant applications and are required for HFC refrig-
erant applications with POE lubricants. Refer to the 5F,H
Installation Instructions for installation and wiring.
INTERCONNECTION OF COMPRESSORS — All 5F,H
compressors are furnished with removable handhole cover
plates on each crankcase. When field interconnection is desired
on 5F40 through 5H86 compressors, cover plates can be
removed and replaced by special cover plates with tapped open-
ings. These tapped cover plates have connections for both oil
and gas equalizing lines. For interconnection of 5F20 and 5F30
compressors, use the opening for the oil sight glass (see 5F,H
Installation Instructions). Cover plates for interconnection are
standard equipment on 5F120 and 126 compressors.
Many refrigeration systems utilize oil management compo-
nents such as an oil separator, oil reservoir and floats. The oil
level control float an be installed in the sight glass connection
in the 5F,H handhole cover plate.
VIBRATION ISOLATORS — A standard vibration isolation
package is available for each 5F,H compressor. This consists of
a standard rubber-in-shear and compression type mounting that
gives an average static deflection of approximately 1/8 in. and
provides reasonably good vibration isolation at 1750 rpm.

The use of vibration isolators is recommended for all com-
pressor and condensing units because:
1. Transfer of vibration to structure is reduced when the
units are installed on upper floors.
2. They limit drive shaft misalignment on installations
where units are bolted to an uneven concrete floor.

An external adjusting stem is provided to set control point
and maintain desired suction pressure. The control point is
adjustable from 0 to 85 psig suction pressure. Differential over
the complete range at any temperature level is 10.7 psig with
Refrigerant 22 and Refrigerant 502. A 7-lb spring (for use on
5F40 and larger units) is furnished with the compressor which,
when used, results in an adjustable control point from 0 to
50 psig with a 6.8 psig range. Insert a spring in the capacity
control valve when R-12 is used. See Fig. 5.
With this arrangement, suction pressure will not drop below
the control set point minus the differential within range of
capacity steps since the compressor will unload to balance its
capacity with evaporator load.
Power elements and valve lifting mechanisms are identical
on all 5F,H compressors. However, when using capacity con-
trol, various methods are used to activate the power elements.
See Table 16 for unloading steps and power requirements at
each step.

Capacity Control — For all 5F,H compressors,
a
pressure-type cylinder unloader is used. On 5F20 and 5F30
compressors, the capacity control valve is external and on 5F40
through 5H126 compressors the valve is located internally. On
all 5F,H compressors, capacity reduction is in response to
suction pressure.
The cylinder unloading mechanism is powered by a
compressor force-feed lubricating system. This feature assures
unloading of all controlled cylinders at starting regardless of

Principle of Operation of the System — An increase in suc-
tion gas pressure, which requires increased compressor
capacity, causes the needle valve to close. Therefore, lubrica-
tion oil pressure in power element increases. Increased oil
pressure in power element moves the power piston upward and
the suction valve discs are allowed to seat.

3. Power Element: Supplies power to operate the valve
lifting mechanism.
4. Valve Lifting Mechanism: Consists of a sleeve and push
pin assembly around each controlled cylinder, designed
to hold the suction valve open, or to permit the valve to
remain in a normal operating position depending on its
actuation by the power element.
Principle of Operation of the System — A decrease in suc-
tion gas pressure, which necessitates a decrease in compressor
capacity, causes the range spring to open the capacity control
modulating valve. This allows control oil to relieve from the
hydraulic relay and thus reduces control oil pressure in the
relay. With reduced control oil pressure, the spring in the
hydraulic relay moves a piston and thus lubrication oil from the
oil pump is prevented from flowing to a particular deactivated
power element. This relieves oil pressure from the power
element allowing the spring in the power element to move the
lifting fork and unload the cylinder. An increase in suction
pressure reverses action and loads cylinders.

Major Elements of Capacity Control Systems:
1. Capacity Control Valve: Function is to raise or lower the
control oil pressure to the hydraulic relay piston in
response to refrigerant suction pressure. Increase in
suction pressure increases control oil pressure in the hy-
draulic relay.
2. Hydraulic Relay: Function is to feed lubrication oil from
the oil pump at full pressure in sequence to one or more
power elements. Relay is activated by control oil pressure
from the capacity control valve.

5H120, 5H126 CAPACITY CONTROL (Fig. 8) — This ca-
pacity control system is slightly different from the system on
5F40 through 5H86 compressors. Unloaded starting and capac-
ity reduction is obtained by holding open the suction valves of
a number of cylinders. For capacity control purposes, a
suction-pressure-actuated capacity control valve pilots a
hydraulic relay that loads or unloads cylinders in pairs.

CAPACITY CONTROL — Adding a control air line to the
external pneumatic control connection permits pneumatic
resetting of the control point in accordance with changes in
operating conditions. Each pound of change in air pressure
resets the control one pound in the same direction. Thus, a one-
pound rise in air pressure will cause unloading to begin at a
suction pressure one pound higher than the original control
point, etc. Figure 9 shows a typical pneumatic control arrange-
ment. All components and installation instructions are field
supplied.

Control Pressurestats — Dual pressurestats are furnished with
all 5F,H compressors. They are often referred to as high- and
low-pressure cutouts. Their function is to cut the circuit to the
holding coil of the compressor motor starter when pressure
setting limits are exceeded.
The high pressurestat has an operating range from 50 to
450 psig with a differential range from 170 to 235 psig (adj).
The low pressurestat has an operating range from 20 in. Hg to
60 psig and a differential range from 60 to 90 psig (adj).
Pressurestat settings should be adjusted on the job to meet
particular operating conditions for which the compressor(s)
have been selected. Directions for setting these pressurestats
are in the 5F,H Installation Instructions.
2. Remove hydraulic relay assembly by removal of two
5/16-in.-18 socket head screws. Make a blank metal disc
using a hydraulic relay gasket (5H120-3351) as a guide.
Using 1/32 to 1/16-in. thick metal, cut holes in the disc for
dowel pins only. (Do not cut five 9/32-in. diameter holes.)
Reinstall relay assembly using 2 new 5H120-3351
gaskets, one on each side of the metal disc. Torque
5/16-in. socket head screws evenly to 16 to 20 lb-ft.
3. Reinstall the bearing head using extreme care not to
damage the oil pump tang. Align with recess in the end of
the crankshaft. Do not force on.
4. Mount solenoid valves and run oil lines. See Fig. 4, 13,
and 16.
Permanently Unloaded Cylinders — Operation of an open-
drive compressor with its cylinders permanently unloaded
requires field modification. The 5F60, 5H40 and 5H60 com-
pressors can operate with one cylinder unloaded; 5H80 and
5H120 compressors can operate with 2 cylinders unloaded.
Compressors are modified by removing the suction valve and
suction valve springs from the cylinder(s) shown in Fig. 4.
5. To minimize vibration, mount the valves on a bracket
attached to the compressor.
Valves — The following 3-way valves have been used in the
field and are listed as a guide:
• Alco Controls No. 702RA001.
• Also Controls No. S608-1.
• Sporlan Type 180.
ELECTRIC SOLENOID VALVE CAPACITY CON-
TROL — Closer control of a conditioned space or medium
can be realized by activating the cylinder unloaders directly in
response to an external step controller activated by solenoid
valves. A temperature sensing controller activates the electric
solenoid valves. Refer to Fig. 10 for an operating concept using
an external electric solenoid-type capacity control. All compo-
nents external to the compressor must be field supplied. Modi-

CAPACITY CONTROL MODIFICATIONS FOR HEAT
PUMP APPLICATION — Where 5F40, 5F60, and 5H com-
pressors are used in refrigerant cycle reversing heat pump
applications, it is usually necessary to modify the standard
capacity control arrangement to satisfy unloading require-
ments. On summer cycle, the compressor is required to unload
as circulating water or air temperature drops. During winter
cycle, the control works in reverse, so that the compressor
unloads as the circulating water or air temperature increases. It
is necessary for the compressor to unload in response to either
a summer or winter temperature-sensing device, depending on
the particular cycle in operation.
5/8”-18 NF
1/4”-18 NPT
Where summer and winter design suction temperatures are
within design range of either electric or pneumatic compensa-
tion devices, capacity control may be external. However,
another means is normally required.
Usually modification to the compressor capacity control
system is required. The compressor can be modified in 2 ways:
(1) for applications requiring 50% capacity reduction; (2) for
applications requiring more than one step of capacity reduc-
tion. See Fig. 10 for a typical 2-step external capacity control
arrangement.

Application Requiring 50% Capacity Reductions — This is
the usual specification for heat pump applications and should
cover majority of cases. The necessary modifications to com-
pressor capacity control can be accomplished by ordering the
compressor with factory modifications and then completing
modification at the jobsite with field-supplied components.
furnishing a compressor with external solenoid unloading type
capacity control. The control can be furnished with or without
3-way valves (Table 18).
Table 18 — Capacity Control Steps and
Heat Pump Modification
Factory Modifications — The compressor order should state
that compressor is to be special for heat pump application, and
is to include only enough unloader power elements to unload
the compressor down to 50% displacement. The unloaded
cylinders will be those closest to pump end of the compressor.
Field Completion — Install a 1/4-in. or /8-in. bypass line
between the control oil pressure connection and the crankcase
and install a solenoid valve in this line.

The cylinders set up for unloading may be loaded or unload-
ed by operation of this solenoid valve. When the solenoid valve
is closed, full oil pressure is available to the controlled
cylinders and these will be loaded so that compressor will be
operating on 100% capacity. When the solenoid valve is open,
oil pressure will be bled from the controlled cylinders and they
will be unloaded, so that compressor will then be operating at
50% capacity. A 2-step thermostat controlling the compressor
can thus utilize 2 capacity steps by operating the compressor
starter and solenoid bypass valve.
Hot Gas Bypass — Hot gas bypass may be required on
some systems for one of the following reasons:
1. Frequent operation at loads below minimum capacity
(compressor fully unloaded).
2. To avoid low-load compressor cycling on the low-
pressure switch. Excessive cycling can reduce equipment
life and increase demand charges.
Application Requiring More Than One Step of Capacity
Reduction — This can be furnished on special order for com-
pressors having 6, 8, or 12 cylinders. Arrangement consists of

control, etc.).

The variety of systems using 5F,H compressors make it
impractical to cover all aspects of hot gas bypass operation.
The following guidelines will aid in determining the proper
application.
The hot gas bypass valve is basically a pressure regulating
valve installed to hold a constant compressor suction pressure.
It should operate over as small a pressure range as possible.
The normal set point of the valve should be coordinated with
cylinder unloaders so that the bypass valve starts to open at a
pressure where the last cylinder bank unloads, and is fully open
at a slightly lower pressure. Types, ratings and published appli-
cation guides for various available valves must be evaluated to
determine the proper valve and installation practice for each
application.
If a compressor system is to operate down to zero load, the
valve capacity should equal compressor capacity when fully
unloaded. For systems using multiple evaporators, it may be
necessary to use multiple hot gas valves.
Hot gas should be taken from a point as close as possible to
compressor discharge and fed through a hot gas solenoid valve
and then through a hot gas valve. The hot gas solenoid valve
can be controlled by a pressure switch or temperature switch.
On compressors equipped with an electrically actuated cylinder
unloader, the hot gas solenoid should be wired in parallel with
the solenoid that unloads the final cylinder bank so that bypass-
ing starts immediately when all cylinders are unloaded.
HOT GAS INJECTION INTO LIQUID LINE — When
amount of bypass is small and the evaporator has a low pres-
sure drop distribution system and existing system piping does
not present problems, hot gas is frequently injected into the
liquid line between the thermostatic expansion valve (TXV)
and the evaporator. The ideal point for hot gas injection is into
the side inlet of a side connection distributor, where inlet is
downstream of distributor orifice. If too much hot gas is
injected upstream of a distributor orifice, gas binding and
erratic expansion valve operation will result. Injection into
liquid line is recommended whenever practical, since agitation
in the evaporator and normal operation of the TXV will tend to
thoroughly desuperheat injected hot gas and prevent compres-
sor overheating.
HOT GAS INJECTION INTO COMPRESSOR SUCTION —
Hot gas injection into compressor suction is sometimes neces-
sary but must be done with caution to ensure sufficient
desuperheating of hot gas and to prevent liquid slugging in the
compressor. Following guidelines should be observed:
1. Inject hot gas as close as possible to the evaporator outlet.
2. Install a TXV bulb at least 3 or 4 ft (further if possible)
downstream from the hot gas injection point to ensure
good gas mixing before the bulb.
3. Install a separate small TXV to inject liquid refrigerant
into the suction line along with bypass gas. This valve
should have capacity approximately 25% of hot gas
valve capacity since hot gas must be superheated but not
condensed.
4. Install a suction (knockout) drum in the suction line
immediately before the compressor and downstream of
the hot gas inlet and liquid injection inlet. Only larger
industrial systems or systems with many remote evapora-
tors can normally justify the extra expense of injecting
hot gas into the compressor suction.
Motor Selection Data — Motor selection data based on
brake horsepower occurring at design operating condition is
usually satisfactory for applications in air conditioning suction
temperature range.
Required compressor starting torque is dependent on dis-
charge pressure as well as pressure differential occurring
during start-up and is the same for any compressor speed.
Values shown in Table 19 indicate maximum starting torque
for R-12, R-134a, R-22, R-502, and R-507/404A. In most
cases, a standard torque motor can be selected because of
the partially unloaded starting feature of the 5F and 5H
compressors.
In selection of a motor, the required motor starting torque
must exceed the compressor starting torque only when the
compressor is operating at same speed as the motor. If com-
pressor speed is less than motor speed, as on some belt drive
units, the motor starting torque requirements are reduced in
proportion to the speed ratio between the compressor and
motor because of mechanical advantage available to the motor.
In special applications or systems where there is a large
pulldown requirement, the bhp requirement during pulldown
may significantly exceed bhp at design conditions. The motor
must not be overloaded during pulldown operation. If the
motor is sized for pulldown, it will be only partially loaded
during design operation and will run inefficiently. Therefore,
select a motor that will be optimized for system design require-
ments and not for pulldown requirements. Two ways for
handling this are:
1. Install a crankcase pressure regulator in the system to
maintain a given saturated suction temperature, thereby
controlling bhp requirement, or
2. Install a current sensing device so that the motor current
draw does not exceed the maximum rated motor current.

components for 5F,H standard belt drive packages. Figure 17

2. The liquid refrigerant at Point A (Fig. 18) at satu-

This occurs when booster discharge gas is condensed in a
cascade (refrigerant-cooled) condenser, or when using an
open flash-type intercooler in a direct staged system.
When subcooling of liquid takes place in a closed-
type intercooler, it is not possible to bring liquid tempera-
ture down to saturated intermediate temperature because
of temperature difference required for heat transfer
through the liquid coil. In this case, the compressor rating
must be decreased 3% for each 10 degrees that liquid
temperature at Point A is above the saturated intermediate
temperature.

“R” Factors — In a multistage compression system, the
intermediate or high-stage compressor must have sufficient
capacity to handle the low-stage (booster) compressor load
plus heat added to refrigerant gas by a low-stage machine
during compression. Likewise, if an intermediate stage com-
pressor should be used, the high-stage compressor must have
sufficient capacity to handle the intermediate stage compressor
load plus heat added to the refrigerant gas by an intermediate
stage machine during compression.

To assist in the selection of higher stage compressors,
Table 23 presents “R” factors that depict approximate required
relationship between stages at various saturated temperature
conditions.
To determine the required capacity of a higher stage com-
pressor, multiply lower stage compressor capacity by the
proper “R” factor from Table 23. Any additional loads handled
at intermediate pressure must be added to this figure to arrive at
the total higher stage load.

Multistage System Pointers — A staged system is
essentially a combination of 2 or more simple refrigerant
cycles. In combining 2 or more simple flow cycles to form a
staged system for low temperature refrigeration, 2 basic types
of combinations are common (Fig. 18).
DIRECT STAGING — Involves use of compressors, in
series, compressing a single refrigerant.
CASCADE STAGING — Usually employs 2 or more refrig-
erants of progressively lower boiling points. Compressed
refrigerant of low stage is condensed in an exchanger (cascade
condenser) that is cooled by evaporation of another lower
pressured refrigerant in the next higher stage.

BOOSTER COMPRESSORS FOR
REFRIGERANT 12, 22, 502, AND 507/404A
Safety Factors — Use of capacity safety factors in select-
ing booster compressors must be a matter of judgment when
making selection.
Factors that have a bearing on satisfactory compressor
selections are: accuracy of load estimate, amount of safety
factor included in the total load, degree of importance of meet-
ing specified capacity at given condition, temperature level of
operation and magnitude of refrigeration load. All of the
factors must be recognized when considering the use of a
capacity safety factor in selecting a booster compressor.
Booster Application Data — The following data sup-
plements the single-stage compressor application data, and
adds information pertaining to booster application only. Refer
to the single-stage compressor data for all other information.
Rating Basis — All booster ratings* are given in refriger-
ation effect and are based on:
1. Use of a liquid-suction heat interchanger. All liquid-
suction interchangers should have a bypass connection on
the liquid side so that adjustment can be made in event
that too much superheating of suction gas causes exces-
sive heating of compressor. This is especially true for
Refrigerant 22, which has a higher compression exponent
than Refrigerant 12.
Figure 19 presents reasonable safety factors for use in selec-
tion of booster compressors. These can be employed when it is
not desired to establish a factor based on selector’s judgment.
29

When a capacity safety factor is used, the compressor is
selected at its maximum speed to handle design load plus safe-
ty factor. Multiplying factors for non-standard speeds are
shown in Fig. 20.
Whether or not added capacity offered by the safety factor is
incorporated at once is a matter of judgment. If it is, then the
compressor will be operated at maximum speed at the start and
any excess capacity achieved will be reflected in faster
pulldowns or lower temperatures. It is also a good practice to
drive the machine at a speed that will provide slightly more
rated capacity than is required by design load. Additional
speed-up available will then constitute reserve capacity in the
event it is needed. Motors should be sized to run the compres-
sor at maximum speed to forestall any motor changes, should
this maximum compressor speed be required in the future.

The use of Fig. 21 (page 32), will allow direct determination
of proper intermediate pressure that will result in equal com-
pression ratios per stage for a direct 2-stage system. Informa-
tion in Fig. 21 is given in terms of saturated temperature
instead of pressures, for easier use with compressor ratings.

Existence of a second appreciable load, at some higher
suction pressure level, will often dictate the most convenient
intermediate pressure.

Gas Desuperheating — Operation of a direct staged
system requires cooling of the gas between stages; otherwise,
highly superheated discharge gas from low-stage machine
would be taken directly into the suction of higher stage com-
pressor and further compression would result in excessive
heating of this compressor.
30
20
15
Liquid Cooling — It is also necessary to employ liquid
cooling between stages and increase refrigeration effect of
liquid delivered to evaporator to realize rated capacity of boost-
er compressor. Amount of refrigeration expended in cooling
liquid between stages is accomplished more economically at
the level of high-stage compressor suction than at the level of
low-stage suction.
Three common methods of gas desuperheating and liquid
cooling for direct stage systems are illustrated in Fig. 18. In
open-type systems, refrigerant liquid is cooled down to the
saturation temperature corresponding to intermediate pressure.
In closed-type systems, good intercooler design usually results
in refrigerant liquid being cooled down to 10 to 20 degrees
above saturation temperature corresponding to intermediate
pressure.

Oil Separators and Lubrication — In cascade-type
systems, where evaporators and suction lines are properly
designed for oil return to the compressor, oil separators are
usually not used.
1
In direct stage systems, however, oil may tend to accumu-
late in one of the stages and thus result in lack of lubrication in
other machine. By use of oil transfer lines, equalization of oil
level between crankcases can be achieved by manual operation
at periodic intervals. Automatic control of proper oil return to
both compressors is effected by use of a high stage discharge
line oil separator, returning oil to high stage machine, and a
high side float, connected to high stage machine crankcase,
which continually drains excess oil from this crankcase down
to the next lower stage compressor (Fig. 18).

Determining Intermediate Pressure — In applica-
tion of commercial compressors to staged systems, the lowest
total bhp per ton and most economical equipment selection
results when using approximately equal compression ratios for
each stage. It is also economical to juggle assigned compres-
sion ratios to fit available sizes of machines.
For booster application, factory oil charge should be drained
and replaced with a suitable viscosity oil for low temperature
application.

After the saturated intermediate temperature is determined
from Fig. 21, the booster rating (Tables 25-27) can be entered
and the compressor selected. Low stage load is then multiplied
by the “R” factor from Table 23 to obtain high stage compres-
sor load. With this information, the Compressor Ratings tables
on pages 7-15, and page 17 can be entered and the high-stage
compressor selected.
Discharge Valve Springs — When 5H compressors
are used for booster applications where discharge pressure is
below 10 psig, the standard discharge valve springs furnished
with the machine should be replaced with an equal number of
lighter weight springs, Part Number 5H41-1801.
No change in discharge valve springs is recommended for
5F compressors.

are not equipped with water-cooled heads but they are avail-
able on special order. Water cooling of heads is generally not
necessary in R-12 or R-502 booster applications. For applica-
tions with R-22 involving high compression ratios, 5 or above,
5F,H booster compressors should be equipped with water-
cooled heads.

Motor Selection Data — In staged refrigeration sys-
tems, the high stage compressor starts first and runs until low
stage pressure has been reduced to a predetermined level
before the low stage machine starts. With direct staged arrange-
ments, the high stage machine draws gas from the evaporator
through low stage machine bypass during this initial period.
Size of the selected motor must be related to the maximum
condition at which booster compressor can operate.
Compressor may run under heavy loads during periods of
high suction pressure, especially on starting when system is
warm. To handle these situations the motor must be sized larger
than the actual balanced operation brake horsepower indicates,
or special attention must be paid to operation of the system
when starting initially. Tables 25-27 give balanced brake horse-
power values at 1750 rpm.
Find: Compressor size and motor size.
Solution:
1. Figure 21 indicates an optimum saturated intermediate
temperature of –2 F. Allow a 1 degree or 2 degree drop
from the booster compressor to intercooler and from the
intercooler to the high stage compressor.
Booster Saturated Suction Temperature = –60 F
Booster Saturated Discharge Temperature = 0° F
2. At –60 F suction and 0° F discharge, the 5H60 booster
compressor has a capacity of 6.8 tons with 12.1 bhp input
at 1750 rpm.
The safety factor at 1750 rpm:
6.8
( 5.7 )
x 100 – 100 = 19.3 or 20%
If the system is to operate only at a fixed low temperature, it
is possible to avoid oversizing of motors providing careful op-
eration is followed when the system is first put in operation.
This is satisfactory from Fig. 19 and a 5H60 compressor
is selected.
3. Indicated hp (ihp) = bhp – Friction hp (fhp)
On applications requiring reduction from ambient condi-
tions to some extremely low temperature, the compression
system will be operated at high suction pressures for consider-
able periods of time. General practice is to drive the high stage
compressor with a motor that will operate compressor at the
highest expected evaporator temperature. This is generally the
“air conditioning” rating of unit. For intermediate or low stage
compressors, it is generally sufficient to size motor to take care
of double the balance load indicated horsepower plus friction
horsepower.
Also consider compressor starting torque requirements
when selecting motor for a booster compressor. Starting torque
of a motor only large enough to provide required normal
operating bhp for booster applications may not be large enough
to start the compressor. Recommended minimum motor sizes
shown in Table 28 have been selected to assure adequate
starting torque. Actual motor size selected is usually larger,
depending on the maximum bhp conditions under which the
compressor will run during pulldown or other abnormal operat-
ing periods.
Where bhp is given in Table 26 and fhp is given in
Table 28.
Indicated hp (ihp) = 12.1 – 3.07 = 9.03
Recommended minimum hp
= (2 x ihp) + fhp
= (2 x 9.03) + 3.07 = 21.13
Tentatively select a 25-hp motor. Assume that low stage
will never start against a saturated discharge higher than
30 F. At 30 F discharge, Table 28 indicates a starting
torque of 54 lb-ft. Therefore, a normal starting torque
25-hp motor is selected.
4. With –60 F suction and 0° F discharge, Table 23 indicates
an “R” value of 1.303. Therefore, the high stage load is:
1.303 x 6.8 = 8.86 tons (actual load)
5. Allowing a 1 degree drop from the intercooler, the high
stage saturation suction temperature is –3 F.
It is good practice to select motors with allowance for 10%
voltage reduction unless there is a certainty that this cannot
occur.
Allowing a 2 degree drop between the compressor and
condenser, the high stage saturated discharge temperature
= 80 + 2 = 82 F.
6. Referring to the 5F,H Compressor Ratings table, 5F60 at
1450 rpm (using multiplier in compressor capacity notes)
has a capacity of 9.21 tons at –3 F suction and 82 F dis-
charge (through interpolation). The 5F60 is selected and
requires 13.0 bhp at 1450 rpm.
7. Assume that maximum load during pulldown occurs at
50 F suction and 90 F discharge. For this condition, the
rating tables (using the multiplier in Step 6) indicate
15.8 bhp, thus a 20-hp motor is selected.
Compressor Starting Torque — Required compres-
sor starting torque is dependent on the discharge pressure as
well as the pressure differential occuring during start-up.
Maximum expected torque required during the starting period
for 5F,H compressors, used as boosters, is shown in Table 28 at
2 saturated discharge temperatures.
Selection Procedure — Selection of a 5F,H booster
compressor requires that the load, saturated suction tempera-
ture, saturated discharge temperature, type of system and
refrigerant are known.

handle load during the first stages of pulldown, when system
capacity is substantially greater than at final condition.
CONDENSERS
Condenser Physical Data — Refer to Table 29. Re-
fer to 5F,H Product Data for information on the current
P701 water-cooled condensers used with the 5F,H water-
cooled condensing units.
If pulldown load is sizable, as in most water or brine cooling
applications, check the condenser performance when it is
handling total heat rejection at maximum rated suction temper-
ature (50 F for most compressors). Condenser size and water
quantity must be adequate to handle this start-up load without
resulting in excessive head pressure or excessive water pres-
sure drop. As a rough guide, the selected condenser should
have a maximum total heat rejection rating that is equal to
or greater than the compressor heat rejection at pulldown
conditions.
Condenser Selection Considerations — On most
installations the condenser is selected within recommended
conditions specified in ARI Standards. Main consider-
ations are:
1. The water velocity is within a range of 1 to 12 ft per
second (to minimize corrosion and erosion).
If this pulldown occurs infrequently, it may be possible to
select a condenser for design conditions and on each start-up
limit compressor capacity by manually throttling suction gas
flow. This can be done by partially closing suction valve but
this will extend time required to reach design conditions.
If the pulldown is of short duration, such as on a direct
expansion coil, suction temperature will drop very rapidly and
more than likely design conditions will be reached before the
compressor would cut out on high pressure. No oversizing of
the condenser would be required.
Whenever possible, the selected condenser should never be
of a larger size than the largest condenser that will match the
compressor used and still be a standard combination. This
should be considered especially when the condensers are to be
used with 5F,H series open reciprocating compressors.
2. It is good practice to select condensers on a leaving tem-
perature difference between 6 and 12 degrees. In general,
higher temperature differences are used only where con-
densing water temperature is quite low or where special
conditions make it economical to do so. A high tempera-
ture difference not only makes effect of fouling more
pronounced but since the condenser volume is likely to be
small, the effect on noncondensable gases will be greater.
Table 30 lists maximum water velocities from Carrier
System Design Manual. Limits are above ARI recommended
values but are generally accepted where ARI conformance is
not specified. See Part 5 of the Carrier System Design Manual
for further details.
Table 31 lists condenser water quantities (gpm) for water
velocities from 3 to 12 fps. For higher velocities, use formulas
below Table 31.
Fouling and Fouling Factors — Fouling in con-
denser tubes is result of a build-up of scale within tubes
because of impurities in water. As a result, heat transfer is
adversely affected. Fouling factors are a means of identifying
degree of fouling.
Condensers should not be selected for less than 0.0005 foul-
ing factor, even when high quality water is available. For lower
quality water, use larger fouling factors from the condenser
ratings, but temper factor according to operating conditions.
Condenser Duty — The capacity of a given compressor
is greatest at high saturated suction temperatures. Because of
this, the compressor normally requires the largest condenser at
these conditions or for air conditioning duty.
On refrigeration or low temperature applications, the same
compressor displacement results in a lower refrigeration
capacity and, consequently, less heat rejection. Thus, con-
denser size is smaller than would normally be required with the
same compressor on air conditioning duty.
The following affect magnitude of fouling factor selected:
• Percentage of yearly operating time.
• Frequency of tube cleaning.
• Condensing temperature.
Condenser size is also affected by refrigerant used, since
compressor capacities (and thus heat rejection) differ with
Refrigerants 12, 22, and 502.
• Type of water treatment.
Pulldown — Condensers for systems subject to pulldown
periods, especially low temperature or multistage systems,
should be oversized beyond the capacity required at the final
balanced load condition. The condenser must adequately
For instance, reduce fouling factor when the operating time
is less than 4000 hours per year, when frequent cleaning of
tubes takes place, or when low condensing temperatures exist.

formula:
Water Circuiting Arrangements — The water cir-
cuiting arrangement selected for 5F and 09RH condensers
depends on available condenser water pressure, temperature,
quantity and source. Refer to Table 32.
Refer to the Carrier System Design Manual for specific
information and recommendations for refrigerant and water
piping.

Economics — Selection of a condenser requires balancing

of certain economic variables, including:

= 7.9
19.3
1. First cost of compressor-condenser combination.
2. Operating costs.
3. Ratio between power costs and water costs.
Where first cost is the most important consideration, the
best combination of compressor and condensers has the lowest
total equipment cost.
Where: EWT — Entering Water Temperature
LF — Loading Factor
THR — Total Heat Rejection
The 85 F value is return water temperature from closed cir-
cuit cooler.
Entering condenser rating data at loading factor of 7.9,
300 gpm are required to maintain design condensing tempera-
ture. Next, determine the rise by:
If owning and operating costs are important, combination
must be selected on basis of both considerations.
A condenser selection that permits operation of the system
at a low condensing temperature, results in the lowest compres-
sor motor brake horsepower and consequently, lowest operat-
ing cost. A condenser selection that is heavily loaded requires
the compressor to operate at a higher condensing temperature
and results in higher compressor motor brake horsepower and
operating cost.

For a given compressor-condenser combination, selection
of a condensing temperature may depend on a ratio between
power costs and water costs, on quantity of water available,
on condensing temperature required to achieve compressor
capacity, or a requirement to remain within allowable loading
on a given motor size.
If a more precise rise is desired, go back and assume a
slightly different condensing temperature, recalculate the load-
ing factor and rise and repeat the procedure until a final balance
is found.
For this example, condenser water pressure drop is approxi-
mately 9.4 ft for the design 300 gpm flow rate. Using Fig. 22,
flow rate correction can be determined for any glycol concen-
tration versus water in shell and tube condensers.
Continuing with example, assume specifications required
protection against freeze-up at an ambient of 0° F. (A glycol
concentration that provides protection between 10 and 15 de-
grees below expected minimum ambient has been the design
criteria for many years.)
In a condenser system, the use of proper ethylene glycol
brine concentration is important because of the phenomenon
that commonly published freeze points are not freeze points but
are the point of crystallization where the first crystals begin to
form. Actual freezing into a solid occurs at much lower
temperatures. For example, freeze point of 20% ethylene
glycol is given as +16 F but does not become a solid until it
reaches –50 F; 35% ethylene glycol with a freeze point of –6 F
does not become solid until it reaches –120 F. Consequently,
20% glycol solution will take care of most domestic applica-
tions and 35% brine should satisfy the rest. The lowest con-
centration of brine will be the most efficient and result in
considerable energy conservation.
Condenser Performance with Ethylene Gly-
col — Increased use of closed circuit cooling towers has led
to a corresponding increase in the need for shell and tube con-
denser ratings for use with ethylene glycol. When towers are
installed outdoors, a brine solution is required for freeze protec-
tion during winter operations.
In most outdoor installations, specifications will call for a
percentage of concentration of ethylene glycol or other brine
solution. If concentration is not specified, it may be the choice
of the contractor to determine a percentage of glycol concentra-
tion to ensure against freeze-up during winter minimum design
ambients.
To perform simplified selection, use Fig. 22 to convert a
condenser water rating to a brine rating.
EXAMPLE:
Assume that a building with a year-round cooling load has a
cooling requirement of 120 tons during summer design condi-
tions. Chilled water design temperatures are 54 F entering to
44 F leaving, and for summer duty, the condenser water is
based on 85 F and a 10 degree rise.
From product literature, selected unit will deliver 121 tons
at 105.8 F saturated discharge temperature (SDT) and has
153 tons of heat rejection.
Entering Fig. 22 at 0° F crystallization point, necessary
concentration of glycol is either 32.5% by weight or 30% by
volume. Next, determine glycol flow rate:

Determine glycol factor (GF) by entering Fig. 22 at proper
glycol concentration and reading left from glycol factor line —
in this case a glycol gpm factor of 33.5.
Next determine the glycol pressure drop.
Equiv Water Flow = Glycol Flow x Press. Drop Factor
Pressure drop factor can be determined by entering Fig. 22
at the proper concentration of glycol solution (30% by vol-
ume), going to the pressure drop factor line and reading right to
the pressure drop factor. For this example the factor is 1.1.

Therefore, at 32.5% by weight ethylene glycol specified and
used to satisfy design conditions, a flow rate of 513 gpm of
brine solution would be required and this value used to select a
closed circuit cooler. Closed circuit cooler selection can be
made from the manufacturer’s literature or by contacting the
local representative.
Equiv Water Flow = 513 x 1.1
=
564 Gpm
Entering condenser water pressure drop curve in product
literature at 564 gpm, the brine pressure drop can be deter-
mined. Note there will be an increase in flow rate and pressure
drop with ethylene glycol as compared to a straight water cool-
ing system.
With the increase in brine flow rate, the rise will now be:

In conclusion, add a glycol solution to a condenser system
only when conditions warrant. Do not add more than is
required. When glycol is used, proper control of inhibitor
concentration is necessary to maintain design properties of
solution and prevent corrosion.
