8.9 Defrosting operation (Available for heating only).
8.9.1 Defrosting condition: Defrosting starts when either of the following ①&②:
① A and B are satisfied:
A: The compressor keeps running for 40 minutes or more.
B: The temperature difference of evaporator and room temperature meets one of the following:
℃
Temp. of evaporator---room temp.
Fan speed is high ≤TH
DEFROST
Fan speed is mid ≤TM
DEFROST
Fan speed is low ≤TL
DEFROST
Breeze Meet only if it is Breeze
② Calculate from the end of latest defrost, evaporator high temp. protection only closes outdoor fan
with the compressor still running. Add up to 90 minutes.
8.9.2 Defrosting time
(a) For defrosting condition ① leading to frost——both condition A and B are satisfied, if B is
satisfied before A, this can be regarded as severe frosting, and the defrosting time is 10 minutes,
or the defrosting time is 7.5 minutes.
(b) For defrosting condition ② leading to frost, the defrosting time is 10 minutes.
(c) For any case leading to frost, if A/C defrosts for 7.5 minutes three times, the forth defrosting time is
10 minutes.
→7.5-minute defrost → 7.5-minute defrost→7.5-minute defrost→10-minute defrost→
8.9.3 Ending condition of defrosting
If one of following conditions is satisfied, end the defrost and turn into heating mode:
A. The defrost time has reached to 7.5 or 10 minutes.
B. The compressor current has reached to I
DEFROST
or above, I
DEROST
