本文介绍了HFC-161制冷剂在小型制冷系统中作为HFC-410A的替代制冷剂。对额定工况下HFC-410A、HFC-32和HFC-161的循环性能进行了理论计算和分析。结果表明，HFC-161的COP分别比HFC-32和HFC-410A高10.0%和17.8%，且HFC-161的排气温度最低。为了比较HFC-410A、HFC-32和HFC-161在不同工况下的循环性能，还对HFC-410A、HFC-32和HFC-161的转子压缩机制冷系统进行了实验测试。实验结果表明，HFC-161的COP比HFC-410A和HFC-32高15~25%，放电温度远低于HFC-410A和HFC-32。在这些制冷剂中，HFC-161的能耗和制冷量是最小的。HFC-32的制冷量和COP与HFC-410A非常相似，但在大多数工作条件下，HFC-32的放电温度和功耗略高于HFC-410A。这些结果表明，HFC-161是一种很有前途的小型制冷系统HFC-410A的替代制冷剂，这对HFC-161的实际系统提供了非常有价值的参考。
In this paper, the refrigerant HFC-161 as an alternative refrigerant to HFC-410A is presented in a small scale refrigeration system. Theoretical cycle performances of HFC-410A, HFC-32 and HFC-161 are calculated and analyzed under the rated working condition. The results show that the COP of HFC-161 is 10.0% and 17.8% higher than that of HFC-32 and HFC-410A, respectively, and the discharge temperature of HFC-161 is the lowest among these refrigerants. Experimental tests were also performed on a vapor-compression refrigeration system with a rotor compressor which was originally designed for HFC-410A to compare the cycle performance of the HFC-410A, HFC-32 and HFC-161 under different working conditions. Experimental results show that the HFC-161 can achieve higher COP by 15–25% than HFC-410A and HFC-32, and the discharging temperature of HFC-161 is much lower than that of HFC-410A and HFC-32. The power consumption and cooling capacity of HFC-161 are the smallest among these refrigerants. The cooling capacity and COP of HFC-32 is very similar to those of HFC-410A, but discharging temperature and power consumption of HFC-32 are slightly higher those of HFC-410A under most working conditions. These results show that HFC-161 is a promising alternative refrigerant to HFC-410A for small-scale refrigeration systems, which supply a very valuable reference for the actual system of HFC-161.
