摘要/Abstract

摘要：

自动复叠制冷在小型制冷低温装置中有较强的应用优势,它能制取氮气液化温度77 K到常规单机压缩制冷温度230 K温区。针对三级自动复叠制冷系统非共沸混合制冷工质不同组分配比进行实验研究,对比分析了R600a、R23和R14混合制冷剂4种组分配比35/35/30、35/30/35、30/35/35和35/25/40,根据压缩机的运行工况和蒸发器的降温特性可以得到4种配比的各项运行性能参数比较接近,组分配比35/30/35的蒸发温度较低。蒸发器设计冷负荷为60 W,设计蒸发温度为180 K,低温冷柜内的蒸发温度最低可以达到并稳定在175 K。根据两种组分配比35/35/30和35/30/35在不同冷负荷时的蒸发器制冷特性实验研究,组分配比35/30/35的最高COP为8.47%;组分配比35/35/30的最高COP为14.4%。

Abstract:

An auto-refrigerating cascade cycle has some unique advantages for small refrigeration units, for which it has a wide range of operation temperatures from 77 K for nitrogen liquefaction to 230 K for conventional refrigeration. For the three-level auto-refrigenerating cascade system, effect of the components ratios of non-azeotropic mixture as a medium on the performances was investigated. Through the experimental comparisons of the performance of compressor and the cooling performance of evaporator, refrigerant mixtures of R600a, R23 and R14 with four ratios of 35/35/30, 35/30/35, 30/35/35 and 35/25/40 were designed, of which all the conditions of evaporator were approximate. The evaporation temperature for the ratio of 35/30/35 was lower than others. For this auto-refrigerating cascade system, its evaporator temperature can be as stable as down to 175 K under conditions of 60 W cooling load and 180 K of designed evaporation temperature. Based on the experimental study on the performances of the two compositions under different cooling loads, the highest COP values of 8.47% and 14.4% for the ratios of 35/30/35 and 35/35/30 were achieved, respectively.
