Selection of Refrigerants Requires Selection of Appropriate Refrigerants
09/09/20191. The working temperature and pressure of refrigerant should be moderate. At atmospheric pressure, the evaporation temperature of refrigerant should be low enough to meet the cooling temperature requirements. At room temperature, the refrigerant should have a relatively low condensation pressure. When the condensation pressure is too high, the structural strength of the sealant of the refrigeration system is required to be high. The condensation pressure of refrigerant is generally required to be 12 *105-15 *105Pa. At room temperature, refrigerant should have relatively high evaporation pressure, because if the pressure in the evaporator is lower than the atmospheric pressure ...Read Mores
What are the selection requirements of refrigerants for refrigerators?
09/09/2019The properties of refrigerants will directly affect the type, structure, size and operation characteristics of refrigerators, as well as the form of refrigeration cycle, equipment structure and economic and technological performance. Therefore, the rational selection of refrigerants is a very important issue. The performance requirements of refrigerants are usually considered in terms of thermodynamics, physicochemistry, safety, environmental impact and economy. I. Thermodynamic Requirements 1. Lower boiling point leads to lower evaporation temperature. At the same time, refrigerants with low boiling point have higher vapor pressure. 2. Higher critical temperature and lower solidification temperature. The critical temperature should be high Read Mores
