Analysis of the cause of excessive suction temperature of compressor

Analysis of the cause of excessive suction temperature of compressor The high suction temperature is mainly due to the increase of superheat of suction. Note that high suction temperature does not mean high suction pressure, because the suction is superheated steam. Under normal circumstances, the compressor cylinder head should be half cold and half hot. If the suction temperature is too high, the cylinder head will all heat up.

Why does the heating system lose water

1. Why does the compressor produce overheat protection? The working principle and classification of the overload protector. The overload protector of the compressor for air conditioning generally adopts a snap-type bimetallic protector,When the pipeline is filled with water, a large amount of dissolved oxygen is mixed into it to cause corrosion; the insulation shell of the directly buried pipeline is disconnected and is subject to long-term soaking of groundwater to cause corrosion.
