the project requests to add refrigerant but it is
not complemented before debugging, then
refrigerant can be added in this process
through the L-VALVE.

discharge temp
℃
●When compressor starts, discharge temp in
cool mode is within 70~105℃ and at least 10℃
higher than the high pressure saturation temp;
●As for temp in heat mode, it is within 65~90℃
and at least 10℃ higher than the high pressure
saturation temp.

Defrosting temp
℃
●In cool mode, defrosting temp is 4~10℃ lower
than system’s high pressure value;
●In heat mode, defrosting temp is about 2℃
