* All values rounded to two decimal places.
EVAPORATOR RANGE: From –6.67 to 7.22³C (20 to 45³F), the temperatures represent the gas temperatures inside the
coil and not on the coil surfaces. Add 1.67 to 5.56³C (3–10³F) to the temperature for coil and air–off temperatures.
CONDENSER RANGE: From 110 to 160³F, temperatures are not ambient. Add 19.4 to 22.2³C (35 to 40³F) for proper
heat transfer, then refer to the pressure chart.
Example:
32³C (90³F) ambient temperature
+ 22³C + (40³F)
54³C (130³F)
Condenser temperature = 1379 kPa (200 psig)
Based on 48.3 km/h (30 mph) air flow.
