Performance Test1. VEHICLE SET UP
In order to obtain meaningful test results, the vehicle must be set up to meet the following conditions:
- Vehicle in shade
- No wind
- All vehicle doors closed
- Front windows open
- Hood open
- Engine speed set at 1,500 rpm.
- A/C ON
- Temperature control dial - Maximum cold
- Air source - Recirculation
- Blower speed - 4th position (High)
- Operate A/C for 10 minutes (Minimum) before taking measurement.
2. MEASUREMENTS
After 10 minutes (Minimum) of A/C operation and using accurate test equipment, take the following measurements (in order):
1. Evaporator intake air temperature at recirculation door.
2. Evaporator discharge air temperature at center grill.
3. Condenser (Ambient) intake air temperature measured 0.9 m (3 ft) in front and in line with the center of the condenser
4. Suction (Low) side pressure
5. 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.
