A: The compressor keeps running for 40 minutes or more.
B: The temperature difference of evaporator temp 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
If the temp. difference condition ① is satisfied for less than 40 minutes, this can be
regarded as severe frosting. The defrosting time is 10 minutes.
If the temp. difference condition ② is satisfied for more than 40 minutes, the defrosting
time is 6 minutes.
If the temp. difference condition ① is satisfied out of 40 minutes, generally the
defrosting time is 6 minutes, after three continuous 6-minute defrosting , the fourth
defrosting time is 10 minutes. The circulation is as following:
→6-minute defrost → 6-minute defrost→6-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:
A. The defrost time has reached to 6 or 10 minutes.
B. The compressor current has reached to I
DEFROST
or above, I
DEROST
differs in different
models.
