Water source heat pump compressor discharge temperature is generally first performed at the high failure analysis: whether a compressor compressor overhaul, if it is overhauled first determine the operation of the machine before overhaul; overhaul before if the machine is stable, then the emphasis The point of failure in that there is a problem of the compressor assembly. 2 detects the compressor suction and discharge pressure is appropriate, whether frozen oil in the normal range, is within the normal range (lack of refrigerant will appear high exhaust temperature); 3 detect motor spray liquid expansion valve is damaged, the compressor intercooler expansion valve damage. 4 condenser door is open, and see whether the condenser is dirty. 5 detection probe position is appropriate, there is no thermal plastic, making the temperature is not accurate, the temperature of the non-stop!
