Danfoss medium temperature refrigeration compressor M series

liquid 1. Liquid back: When the refrigerant returned to the compressor is not a pure gas state, but contains liquid, the influence of the liquid refrigerant on the compressor is negative. If there is too much liquid, it may even cause liquid shock, even if there is no liquid shock, it will happen. Wet compression causes oil to run away.

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="" />
