7 Air Conditioner Performance Evaluation
Suction & Discharge Air
Temperature Difference
• 8°C and over (14.4°F)
• 8°C and over (14.4°F)
• Under 8°C (14.4°F)
• Under 8°C (14.4°F)
• Under 8°C (14.4°F)
Note: Room air humidity is relatively higher, the temperature difference will be smaller.

C-S
Capacitor
CWA312066 (40µF,
250VAC)
Note: Resistance at 20°C of Ambient Temperature.
Determination
• Nothing wrong.
• Nothing wrong, outdoor
temperature is too high, heat
radiation is not efficient.
• Something is preventing heat
radiation.
• Leakage of refrigerant or
refrigerant system is blocked.
• Compressor defect.
