If the refrigerant liquid is not cooled by the economizer, it can be kept warm without baggage; At this time, the liquid temperature is about 35 ° C, which is similar to the ambient temperature, or even higher;
However, in fact, in general small cold storage, the liquid pipe and the return pipe often walk together, and the cold capacity of the return pipe can be used to cool the refrigerant, produce a favorable superheating effect, and improve the refrigeration efficiency;
-20 degree cold storage requires more than 30mm rubber and plastic insulation pipe
