15.5.18. F91 (Refrigeration Cycle Abnormality)
Malfunction Decision Conditions
• During cooling, compressor frequency = Fcmax.
• During heating, compressor frequency > Fhrated.
• During cooling and heating operation, running current: 0.65A < I < 1.65A.
• During cooling, indoor intake - indoor pipe < 4
°
C.
• During heating, indoor pipe - indoor intake < 5
°
C.
Multi Models Only
- Gas shortage detection 1: A gas shortage is detected by checking the CT-detected input current value and the compressor
running frequency. During startup and operating of cooling and heating, input current < 8.78/256 (A/Hz)
×
compressor
running fre 0.25.
- Gas shortage detection 2: A gas shortage is detected by checking the difference between indoor pipe temperature and indoor
intake air temperature during cooling and heating.
Malfunction Caused
• Refrigerant shortage (refrigerant leakage).
• Poor compression performance of compressor.
• 2/3 way valve closed.
• Detection error due to faulty indoor intake air or indoor pipe temperature sensors.
