The medium and high temperature heat pump can use 25~60 waste heat...
In this process, due to the rapid drop in the pressure inside the evaporator, the liquid working medium in which it resides absorbs a large amount of its own heat and vaporizes it, and then is compressed and sent to the condenser. It takes a certain amount of time for the excess working fluid of the evaporator to completely return to the condenser. During this time period, although the compressor is working, the system has no cooling output. In other words, this process consumes power but does...
Industrial clusters refer to a large number of closely-connected companies gathering in a specific area and forming advantages in competition and cooperation.

When the pressure in the high pressure chamber of the compressor reaches 180, the casing begins to undergo expansion deformation. When the compressor is compressed, such high pressure cannot be achieved due to motor torque limitation. Therefore, there may be abnormal physical and chemical changes in the compressor machine resulting in high pressure. The compressor continues to compress the refrigerant, and the exhaust temperature rises rapidly; at the same time, the exhaust pressure rises...
The noise of the compressor mainly comes from the compressor's own operation, and the refrigerant flow noise comes from the various refrigeration components and refrigeration pipelines.
