Performance Test: Inspection: Measurements
After 10 minutes (Minimum) of A/C operation and using accurate test equipment, take the following measurements (in order):
- Evaporator intake air temperature at recirculation door.
- Evaporator discharge air temperature at center grill.
- Condenser (Ambient) intake air temperature measured 0.9 m (3 ft) in front and in line with the center of the condenser
- Suction (Low) side pressure
- Discharge (High) side pressure
NOTE:
If only one thermometer is available; 1) take the ambient measurement first; then 2) the intake air; and 3) discharge air temperature.
