Description
technical field [0001] The present invention relates to the technical field of refrigeration system regulating valves, and more particularly, the present invention relates to a condensing pressure regulating valve. Background technique [0002] Condensing pressure is one of the main operating parameters in the refrigeration cycle, which directly affects the refrigeration effect, safety, reliability and energy consumption of the refrigeration unit. When the condensing pressure is high, the compression ratio increases, the volumetric efficiency decreases, the cooling capacity decreases, the power consumption increases, and the exhaust temperature increases. The higher the condensing pressure, the greater the degree of its adverse effect. The phenomenon of high condensing pressure mainly occurs in summer. At this time, the condensing pressure should be reduced as much as possible to ensure the economy and reliability of the system operation. However, for a refrigeration syste...
