环保节能工质HFE143a的热力学性质和制冷性能的深入研究

Fluorinated ether substance F-methyl methyl ether(HFE143a, CH3O CF3) used as a refrigerant for refrigerator is analyzed in detail. The Thermophysical properties of the new refrigerant HFE143a and the original refrigerant CFC12, HFC134a, HC600a and HFC152a/HCFC22 are compared. The performances of refrigerator refrigeration cycle of standard operating condition and that of variable operating condition are calculated and analyzed theoretically. The mathematics model of refrigerator refrigeration system based on neural net method has been established, and the refrigeration performance and working parameter of refrigerator have been obtained when using all kind of refrigerants. The results indicate that the refrigeration performance of HFE143a is similar to CFC12 and HFC134a, the farmer's energy consumption is lower than the latter's'. As a new type of refrigerant for refrigerator, HFE143a can meet the higher environment request. The test of refrigerator performance and its thermophysical properties are carrying out when charging with HFE143a. Through the research of the program, there is a good base on the application of the new generation environmental acceptable and energy-saving refrigerant to refrigerator industrial production.
