Energy Adjustment of Refrigeration Compressor of Industrial Refrigerator

Energy Adjustment of Refrigeration Compressor of Industrial Refrigerator In addition to the intermittent operation of the compressor, the energy adjustment of the refrigeration compressor of an industrial refrigerator can also be achieved by changing the passage area of ​​the compressor suction stop valve. If the area of ​​the cut-off valve channel of the refrigeration compressor of the industrial chiller is reduced, the flow resistance of the suction steam will increase, and the steam will be throttled, resulting in a corresponding decrease in the pressure of the suction chamber,

How to solve if the air conditioner is not cooling

If it is not in the cooling state, we can adjust it to the cooling mode; if the dust accumulation of the air conditioner severely reduces the cooling function, we can find professional personnel to disassemble the evaporator, fan blade, and filter. Completely clean up; if it is because no refrigerant is added, then we can add refrigerant.
