摘要
本文根据单级蒸气压缩制冷循环的冰箱制冷系统设计归纳出来常用循环类型,并对目前节能冰箱制冷系统汇总分析,提出了一种降低能耗的技术即冷凝保压技术,并对单级蒸气压缩系统采用冷凝保压技术的循环进行分析。
This paper bases on the design of refrigerator＇ refrigeration system which is single fume compression, induces to the normal circulating type. It gives analysis to the super-energy-saved refrigerator＇ refrigeration system. It also gives technique, which is called condensation-pressure-ensure, to improve the tradition energy-saved ways merely by increasing bubble layer＇ thickness and using high COP compressor. It offers contrast analysis on the circle system which adopting condensation-pressure-ensure technique and not adopt ones from thermodynamics. And the paper sum up the best match relationship among condensate pressure, evaporate pressure, condensate temperature, evaporate temperature, the returned fume ＇temperature and refrigerant＇s amount, and gives the best composite parameter.
