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, the mass of the steam increases, and the refrigeration of the industrial chiller The mass flow of the compressor is reduced to achieve the purpose of energy regulation. This energy adjustment method of suction throttling is not economical enough. Even if this energy adjustment method is used, it is only used in large industrial refrigerators, but it is currently less used in China. Therefore, enterprises can directly achieve energy regulation through intermittent operation of the compressor, thereby achieving the purpose of energy saving. The intermittent operation of the compressor is the most widely used and simplest energy adjustment method for the industrial chiller of the enterprise. It uses the temperature controller of the industrial chiller or the low-pressure pressure controller to automatically stop or run the refrigeration compressor of the industrial chiller by using two positions, so that the compressor can quickly adapt to the requirements of the cooling load and cooling temperature of the cooled space. . When the temperature of the cooled space of the industrial chiller or the corresponding evaporation pressure reaches the lower limit, the refrigeration compressor of the industrial chiller will stop running, and when the temperature or the corresponding evaporation pressure rises to the upper limit, the compression The machine is restarted and put into operation.
