Abstract
Ecohol 1ozone-safe mix (0.8R125/5.7R600a/93.5R134a) is proposed to be applied for shift of refrigerating car set cooling equipment from C10M1 mixed ozone-unsafe refrigerant without change of mineral refrigerator oil. Efficiency of the mix was proved for the boiling range from – 8 to – 31° C in vaporizer at TH-1M upgraded facility with oil separator installation for refrigerator oil return into compressor crankcase. The paper deals with description of TH-1M facility as well as test results and their agreement with data on Ps-Ts dependences of Ecohol mix before and after the tests. Recommendations for upgrading of refrigerating car set cooling equipment and the application of the Ecohol ozone-safe mix without change of mineral refrigerator oil are given. It allows significant reducing the cost of the refrigerating car set cooling equipment shift to Ecohol 1mixed ozone-safe refrigerant.
