The cold storage was built in this way, which actually saved nearly half of the electricity bill!

Compared with the ordinary refrigerator, the cold storage has a larger cooling area, and because of the large cooling area of ​​the cold storage, the power consumption is relatively large.

Correct adjustment method of opening degree of thermal expansion valve

The expansion valve is one of the four major components of the refrigeration system. It is an important device for regulating and controlling the flow and pressure of the refrigerant entering the evaporator, and it is also the "boundary line" between the high and low pressure sides.

Classification of air-conditioning compressors

The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The working circuit is divided into an evaporation area (low pressure area) and a condensation area (high pressure area). The indoor unit and outdoor unit belong to the high-pressure or low-pressure area (depending on the working state), and the compressor is generally installed in the outdoor unit.
