The role of condensing pressure regulating valve

Condensing pressure regulating valve 　　 When the refrigeration device is running, if the condensing pressure is high, the compressor discharge temperature will rise; the compression ratio will increase; the cooling capacity will decrease; The higher the condensing pressure, the greater the above adverse effects. The high condensation pressure is mainly seen in summer. <img src="{{media url=&quot;The_role_of_condensing_pressure_regulating_valve.jpg&quot;}}" alt="" />
