For Air Cooled Oil Systems, FIGURE 5–10 shows the
normal upper limit of discharge temperatures for vary-
ing ambient temperatures beginning at the system de-
sign point of 80
_
F. At ambient temperatures below 80
_
F., the mixing valve will hold the discharge temperature
at the 80
_
F. ambient temperature point. Above 80
_
F.,
the oil cooler is fully used and the discharge tempera-
ture varies degree for degree with the ambient temper-
ature.
For Water Cooled Oil Systems, the water flows at vari-
ous temperatures outlined in Section 2 will hold the dis-
charge temperature below the 80
_
F. ambient tempera-
ture level of FIGURE 5–10. Small variations in specific
water flows or temperatures will not be noted in the dis-
charge temperature since the water control valve will
tend to hold a constant oil temperature. A significant
change in the discharge temperature is cause to check
for a change in water flow or temperature.
Oil Inlet Pressure – Check at the fitting in the line near
the compressor oil inlet. With air receiver pressure at
100 psi, oil inlet pressure should be 75–85 psig.
Oil Cooler Oil Pressure Differential (Air–Cooled
Radiator) – 2 to 25 PSI (65 to 150 PSIG Receiver Pres-
sure) – Check at the fitting in the inlet and outlet lines
of the oil cooler.
Oil Cooler Oil Pressure Differential (Water–Cooled
Heat Exchanger) – 2 to 25 PSI (65 to 250 PSIG Re-
ceiver Pressure) – Check at the heat exchanger oil inlet
and outlet fittings.
Oil Cooler Temperature Differential (Air–Cooled
Radiator) – The oil temperature differential depends
on the temperature of the air at the oil cooler fan and
cleanliness of the core faces. As ambient tempera-
tures and core restrictions increase, the oil cooler outlet
temperature will increase. The inlet oil temperature
may be checked at the fittings in the oil inlet line on the
oil cooler module. The outlet oil temperature may be
checked at the fitting in the oil outlet line.
Oil Cooler Temperature Differential (Water–Cooled
Heat Exchanger) – The oil temperature differential de-
pends on the inlet water temperature and the water flow
rate permitted by the water flow control valve setting.
The oil inlet temperature is approximately the same as
air discharge temperature – see the gauge on the
instrument panel. The outlet oil temperature may be
checked at the compressor oil outlet line fitting.
Oil Cooler Water Pressure Differential (Water–
Cooled Heat Exchanger) – The water pressure differ-
ential through the heat exchanger will depend on sup-
ply pressure, flow rate, cooler tube cleanliness and
outlet pressure. The inlet and outlet water pressures
may be checked at the pipe fittings supplied by the cus-
tomer.
