6. Air Conditioner Performance Evaluation
Suction & Discharge
Air Temperature
Difference
Current Determination Remedy
-8°C and over (14.4°F) -As specified. -Nothing wrong. -None.
-8°C and over (14.4°F) -Higher than specified. -Nothing wrong, outdoor
temperature is too high, heat
radiation is not efficient.
-Improve heat radiation.
-Under 8°C (14.4°F) -Higher than specified. -Something is preventing heat
radiation.
-Excessive amount of
refrigerant.
-Improve heat radiation.
-Under 8°C (14.4°F) -Lower than specified. -Leakage of refrigerant or
refrigerant system is blocked.
-Locate and repair leak.
-Flush refrigeration cycle.
-Under 8°C (14.4°F) -Higher than specified by 50%. -Compressor defect. -Replace the compressor.
Note: Room air humidity is relatively higher, the temperature difference will be smaller.
