2-1 Defrost operation
(1) Overview
Defrosting begins during heating if the conditions for compressor operation time and outdoor heat exchanger
temperature are met.
When defrosting begins, the indoor and outdoor fans stop.
Defrosting stops when the temperature of the outdoor heat exchanger goes above approximately 10˚C or defrosting
time exceeds 13 minutes.
AU-X079E/X099E are not provided with the heating function.
(2) Defrosting
If the compressor operation time is more than 20 minutes in the heating mode and the outdoor air temperature and
outdoor heat exchange temperature satisfy the defrosting conditions, the defrosting operation is started.
When the defrosting operation is started, the indoor fan starts to run intermittently.
When the outdoor suction pipe temperature reaches approx. 4°C or above or when the defrosting time exceeds 12
minutes, the defrosting operation is quit.
The defrosting zone is an outdoor heat exchanger temperature of under approximately -4˚C.
(3) During defrosting
When defrosting begins, the compressor stops. Approximately 3 minutes later, the compressor reactivates in the
refrigeration cycle, and the outdoor heat exchanger is defrosted.
Each mode is as follows:
The outdoor fan is stopped
The operating frequency is as shown in the table below
The indoor fan is stopped
(4) Defrost stop
When defrosting time exceeds 13 minutes
When the temperature of the outdoor heat exchanger rises above approximately 10˚C
Defrost stop is determined by either of the above conditions, and the compressor is stopped.
At the same time, the outdoor fan go ON. The compressor is reactivated in the heating cycle 3 minutes after it was
stopped, and normal control resumes.
