Discharge tube temp of
inverter compressor 1
℃
●When system compressor starts up, temp of discharge
tube or casing top in cooling mode is within 70~95
℃
, and
at least 10
℃
higher than system high pressure saturation
temp; Temp in heating mode is within 65
℃
~80
℃
, and at
least 10
℃
higher than system high pressure saturation
temp.
●When inverter compressor starts but inverter compressor 2
stops, the discharge tube temperature of inverter
compressor 2 is almost the same with ambient temp.

Defrost temp 1
℃
●In cooling mode, defrost temp1 is 5~11
℃
lower than
system high pressure value;
●In heating mode, defrost temp1 is about 2
℃
different from
system low pressure value.
7
System high pressure
℃
●System’s normal high pressure value is within 20
℃
~25
℃
.
According to the change in ambient temp and system
operational capacity, system’s high pressure value is 10
~40
℃
higher than ambient temp The higher ambient temp
is, the smaller temp difference is.
●When ambient temp is 25~35
℃
, system’s high pressure
value in cooling mode is 44~53
℃
.
●When ambient temp is -5~10
℃
, system’s high pressure
value in heating mode is 40~52
℃
.
8
System low pressure
℃
●When ambient temp is 25~35
℃
, system’s low pressure
value in cooling mode is 0~8
℃
.
●When ambient temp is -5~10
℃
, system’s low pressure
value in heating mode is -15~5
℃
.
