Compressor Temperature Affected Condensing Unit for Cold Room

Condensing Unit for Cold Room Will Be Affected by Compressor Temperature

condensing unit for cold room

The compressor suction temperature is the temperature of the refrigerant at the suction of the compressor. To ensure the safe operation of the compressor and prevent the occurrence of the phenomenon of the system liquid hitting the cylinder, the suction temperature of the compressor is required to be higher than the evaporation temperature of the warehouse, that is to say, properly control the refrigerant vapor inhaled by the compressor to be superheated gas. Generally, the difference between the suction temperature and the evaporation temperature is called the suction superheat.

The suction overheat of the refrigeration system is divided into harmful overheat and beneficial overheat. Harmful overheating refers to the overheating caused by the absorption of environmental heat after the evaporator. Harmful overheat reduces the coefficient of refrigeration and increases the heat load of condensing unit for cold room, so it is unfavorable and should be minimized. The freon system should minimize harmful overheating to reduce energy consumption. Beneficial overheating refers to the overheating generated in the evaporator. For refrigerants with increased refrigeration coefficient of the regenerative cycle, beneficial overheating can increase the refrigeration coefficient, so a larger suction superheat can be used. For the refrigerants with no obvious change in the coefficient of refrigeration, a certain degree of superheat is conducive to the normal operation of the system. However, if the suction superheats are too high, the exhaust temperature and pressure will increase. Therefore , the suction superheat should be determined according to the evaporation temperature, the superheat of the suction pipe, the type of refrigerant, and the way of refrigerant supply.
