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.
