This publication contains application infor
mation for Carrier 38AD, AE, BA, and GR con
densing units used in split systems with 40RR
direct-expansion air handling units, including
system selection, performance data, combination
ratings, electrical and control data, and refrigerant
piping details.

Enter the Systems Index at the desired cfm
(20,000). Select the condensing unit(s) and
fan-coil system that meets or exceeds the grand
total load (600,000 Btuh). In this example,
system no. 48 would be selected — two 38AD
024 and one 38AD016 condensing units and a
40RR054 fan-coil, yielding a nominal capacity
of 632,000 Btuh. To determine whether this
system will fully satisfy the cooling require
ments, enter the combination ratings, system
no. 48, page 9, at 20,000 cfm and 95 F condenser
entering air temperature. By interpolation, at

EER — Energy Efficiency Ratio
ТС — Total Capacity (1000 Btuh)
*ARI capacities, Energy Efficiency Ratios rated in accordance with
tFor units operating at 208 v, deduct 1000 Btuh from capacity
the system has a total capacity (TC) of 600,800
Btuh, and a calculated sensible heat capacity
(SHC) of 498,800 Btuh. For close-coupled
systems (15 ft or less of interconnecting pipe),
an additional 2% may be added to both TC and
SHC. As this system is not close-coupled, the
ratings are used directly from the combination
ratings. At this point, the sensible heat capacity
is adjusted for the evaporator entering air db
temperature. For 20,000 cfm, the bypass factor
is 0.18. The adjusted sensible heat capacity is:
Adj SHC = SHC + [1.09 X cfm x (1—bf)
X (edb-80)]
= 498,800 + [1.09 X 20,000
X (1-.18) X (77-80)]
= 498,800- 53,600
= 445,200 Btuh
Therefore, the selected system will meet all
cooling requirements.
Find heating capacity of selected fan-coil unit.
Enter Table 3, page 10, for 40RR054 and
20,000 cfm. A one-row nonfreeze steam coil
will deliver 915,000 Btuh based on 60 F enter
ing air temp, and 2 psig steam. To find the
corrected heating capacity, enter Table 1, page
10, for steam coils at 5 psig steam and 58 F
entering air temperature. By interpolation, the
correction factor is 1.062.

The heating coil has sufficient capacity and the
leaving air db is less than the maximum
temperature of 140 F.
IV Determine fan rpm and bhp.
Refer to Table 14, page 17, for a 40RR054 at
20,000 cfm and 1.12 in. wg external static
pressure, plus 0.07 in. wg for the heating coil
(Table 4), indicates a fan rpm of 828 and
requires 12.6 bhp. As this rating point is within
the shaded area, the fan drive must be selected
and purchased locally.
V Determine size of liquid and suction lines.
Table 11, page 14, indicates the pipe sizes for
the various condensing units. These sizes are
based on an equivalent length equal to the
maximum length indicated plus 50% for fit
tings. A more accurate estimate may result in
smaller pipe sizes. Enter the table with the
condensing unit (38AD024) and the estimated
length of interconnecting pipe (90 ft). The
suction line will be 2 1/8-in. OD and the liquid
line is 7/8-in. OD. Similarly, for the 38AD016,
the suction line is 2 1/8-in. OD and the liquid
line is 7/8-in. OD. If a 38AD034 — 38AE054
condensing unit is used with more than 25 ft of
piping, a double suction riser may be required.
VI Find size nozzle, TXV and solenoid valve.
To determine the nozzle(s), TXV(s), and sole
noid valve(s), enter Table 6, page 13, with the
system number. Tables 7, 8, 9, and 10 give the
part numbers for the keys indicated in the
previous table. For this example, a C12 nozzle
would be used in each of the 3 distributors.
Also, the TXV’s and solenoid valves used would
be (using Carrier Part No.):

Part numbers for Alco and Sporlan valves are
obtained in a similar fashion. Also, for several
systems, a single solenoid valve will control
both the middle and lower coil sections as
exemplified by system no. 49. These systems
should be piped in accordance with Fig. 5, page
16. When the condensing unit is below the
fan-coil unit, the maximum liquid lift as pre
sented in Table 13, page 15, should be adhered
to.

COMBINATION RATINGS
Ratings Notes
1. Direct interpolation is permissible. Do not
extrapolate.
2. SHC is based on 80 F db temperature of air
entering evaporator coil.
Below 80 F db, subtract (corr factor x cfm)
from SFIC.
Above 80 F db, add (corr. factor x drn) to SHC.

REFRIGERANT PIPING
Use of liquid line solenoid valves
38BA008,009; 38AD012 —016 single evaporator
coil applications; liquid line solenoid valves not
required.
38AD012 — 016 dual coil applications; single
liquid line solenoid required to deactivate upper
second-stage coil.
38AD024 — 034 liquid line solenoid valves re
quired for each evaporator coil stage.
38AE044 — 064 may require liquid line solenoid
valves in 2 types of applications. In installations
requiring 125 ft or more of interconnecting piping,
solenoid valves are required on all coil splits to be
operated by the solenoid drop relay that is
installed in the unit. In installations where the
compressors are able to unload to a very low per
centage of full load, it is usually necessary to install
liquid line solenoid valves on one or more of the
coil splits to assure sufficient refrigerant velocity in
the coil to return oil to the compressor.
The 38AD024 — 034 units are wired for single
pumpout control. Field-supplied liquid line sole
noid valve(s) is required to restrict the flow of
refrigerant to the evaporator during the off cycle.
When the thermostat is satisfied, the liquid line
solenoid valve(s) will close. The unit, however, will
continue to run, evacuating the low side, until the
low pressurestat opens.
The 38BA008,009, 38AD012016, and
38AE044 — 064 do not require single pumpout
control or a liquid line solenoid drop when the unit
is de-energized unless the interconnecting piping
exceeds 100 ft (125 ft in the Model 38AE).
Field-supplied liquid line solenoid valves are
required on multi-evaporator coils to deactivate
upper portion of evaporator coil surface in order to
unload compressor (suction-activated unloaders) at
part-load conditions and provide single pumpout
control when last solenoid drops. Pumpdown
control is not recommended.
Solenoid drop protection (liquid line solenoid
valve closes, compressor shuts off and crankcase
heaters energize simultaneously) is recommended
for Series 10 cooler applications. Single pumpout is
not recommended for Series 10 cooler applications
because of possible damage due to frost pinching
of cooler tubes.
Oil return — Condensing units with multi-step
unloading may require double suction risers to
assure proper oil return at minimum load operating
conditions. Reduction of evaporator coil surface
should be analyzed to provide sufficient refrigerant
velocity to return oil to the compressor. Liquid
line solenoid valves may be used in certain situ
ations to accomplish this. Bypass hot gas, if used,
should be introduced before the evaporator.
Consult Carrier System Design Manual.
Insulation — Refrigerant suction piping should be
insulated in accordance with guidelines set forth in
the Carrier System Design Manual.
Additional consideration should be given to
insulating the liquid line to prevent sweating when
low-temperature operation is expected. Since
refrigerant flashes and migrates to the outdoor coil
during off cycle due to lower outdoor coil pressure
(resulting from low outdoor temperature), the
refrigerant temperature in the liquid line may drop
below the indoor air dew point.
•Requires double suction riser, see Table 12.
NOTES:
1 Pipe sizes are based on a 2 F loss for liquid lines and a 1 5 F
loss for suction lines If the suction line is piped according to
Fig. 5 which results in a 0 5 F line loss, the pipe sizes given
result in total suction line loss of 2 F
2 Pipe sizes are based on an equivalent length equal to the
maximum length of interconnecting piping plus 50 percent
for fittings A more accurate estimate may result in smaller
sizes and eliminate the need for a double-suction riser
3 If units are close coupled, add 2 percent to combination
ratings
4. Units should be charged in accordance with the Installation
