7 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.
