摘要
本文针对恒温槽的R404A/R508B复叠式制冷系统进行实验探索,通过在恒温槽中搭建R404A/R508B复叠式制冷系统,调整物性参数,并观察记录高低温端制冷系统的各项运行参数,客观评价制冷系统的运行状况并得出结论,即R404A/R508B复叠式制冷系统能够稳定运行,且能够实现了-86.9℃的蒸发温度和-80.2℃的测量腔温度。
In this paper,the R404A/r508b cascade refrigeration system in the constant temperature bath is experimentally explored.By building the R404A/r508b cascade refrigeration system in the constant temperature bath,adjusting the physical parameters,observing and recording the operating parameters of the refrigeration system at the high and low temperature ends,objectively evaluating the operation status of the refrigeration system,and drawing a conclusion that the R404A/r508b cascade refrigeration system can operate stably,The evaporation temperature of-86.9℃and the measurement chamber temperature of-80.2℃can be realized.
