【摘要】 基于R22/R23非共沸工质对,结合自动复叠式制冷循环实验装置,实验研究了一定混合比的工质对在不同高温温度、低温温度下,蒸发冷凝器高温工质出口温度对低温制冷量、压缩机功耗、COP值的影响。研究结果表明:工质对为R22/R23时,低温箱温度可以达到-70℃且效率较高。本文的研究成果对自动复叠制冷系统的实用产品设计有一定的参考价值。更多还原

【Abstract】 This article based on R22/R23 zeotrope workers,combined with automatic cascade refrigeration circle experimental device,has studied zeotropic mixed workers in the conditions of different high temperatures and low temperatures,the evaporator export temperature affects on refrigeration volume,compressor power,and COP value and through experimental research for comparison.Results show that when working pairs for R22/R23,temperature can be down to-70 ℃ with high efficiency in the freezer.Researching results have a certain degree of practical reference value to the product design process on the auto cascade refrigeration system.更多还原
