闪发蒸汽冷却技术及 R134a 用于高温空调器的研究
Study on the High Temperature Air-conditioner Based on Flash Evaporative Cooling Technology and Using R134a as Refrigerant
摘要
Abstract
Mathematical model of the high temperature air-conditioner based on flash evaporative cooling technology and using R134a as refrigerant were developed.Condensing pressure,compressor’s discharge temperature and input power,refrigerating ca-pacity and coefficient of performance (COP)of refrigeration systems including refrigeration system with R134a as refrigerant,sin-gle stage compression refrigeration system with R22 as refrigerant and flash evaporative cooling technology based refrigeration sys-tem also using R22 as refrigerant were analyzed.Results showed that refrigeration system using R134a as refrigerant had the lowest condensing pressure,compressor discharge temperature and refrigerating capacity when three refrigeration systems worked in same condition,and this system was more suitable for the condition that environment temperature was higher than 50℃.Compared with single stage compression refrigeration system with R22 as refrigerant,flash evaporative cooling technology could effectively reduce the compressor discharge temperature and improve the refrigeration system’s capacity and COP with slightly higher power con-sumption and condensing pressure when the environment temperature was between 42 ~50 ℃.关键词
