摘要
针对冷冻冷藏领域转子式压缩机,R455A、R454C制冷剂在不同蒸发温度下进行测试,与目前使用最为广泛的R404A进行对比分析,得出结论,在蒸发温度低于-20℃,R404A性能最优;蒸发温度高于-20℃,R455A性能最优;蒸发温度在-40℃~-5℃,R454C功率及电流均比R404A、R455A偏低。
R455A and R454C for rotary compressors in the field of refrigeration are tested at different evaporation temperatures, which is comparing with R404A. When the evaporation temperature is lower than-20 ℃, the performance of R404A is better. If evaporation temperature is higher than-20 ℃, R455A is better. When the evaporation temperature is-40 ℃~5 ℃, the power and current of R454C are lower.
