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,
