CONTROL SYSTEM
-1
℃
.when indoor fan wind speed climbs 1 grade, temperature modifi1
℃
c) Condition No.3
①
The compressor accumulating running time ≥3h
②
The continuous
compressor running time ≥5min
③
The min. difference between TE and TA
<
16
℃
d) Condition No.4
①
The min. difference between TE and TA
<
16
℃
continuously last for 5 min
②
The compressor accumulating running time ≥45 min
③
The compressor continuous running time
≥20min
If the condition is satisfied unit will enter into defrosting, current TE will be recorded before defrosting. When the defrosting is
over, and the compressor continuously runs for 10 min, then compare current TE
with TE before defrosting, if the lat
ter doesn’t high than former by 3
℃
or more, next time unit will not
enter into defrosting at this condition, until mode switch, turn off then restart to heating or go through a defrosting yet.
e) Condition No.5
Begin to calculate time once air conditioner enters into over-heating protection, enters into compulsory defrosting after 2 h
later.
f) Condition No.6
①
5 min later after enters into heating mode for the first time, catching max value of TE, if TE
<
38
℃
②
The compressor continuous running time ≥5min
③
The compressor accumulating running time ≥45 min
g) Condition No.7
①
At heating mode and the compressor accumulating running time is over 2h.
②
Within the 2 h never carry out defrosting
③
The compressor continuous running time ≥5min, catching max value of TE, if TE
<
30 and lasting
time ≥3min.
