本文提出HFC-161作为HFC-134a的替代品用于小型汽车空调。根据之前的工作，HFC-161具有一些优异的热物理特性。首先开发了理论循环分析来分析在蒸发温度为-5°C至10°C、冷凝温度为50°C至65°C时用HFC-161替代HFC-134a的可行性。基于理论结果，对HFC-161和HFC-134a的循环性能进行了实验比较。该实验在单级压缩制冷系统上进行，该系统配备专为 HFC-134a 设计的压缩机。理论上，HFC-161 的 COP 与 HFC-407C 的 COP 非常接近； HFC-161的比制冷效应和体积制冷效应分别比HFC-134a大约50%和38%。实验结果表明，在-5℃、0℃、5℃蒸发温度下，HFC-161的COPs高于HFC-134a； HFC-161的制冷量和压缩机功耗分别比HFC-134a大约56%和47%； HFC-161 的压缩机排气温度比 HFC-134a 高 20–35 °C。实验数据与理论数据相符。鉴于HFC-161良好的环保性能，分析HFC-161替代HFC-134a的可能性具有重要意义。
In this paper, HFC-161 is proposed as a substitution of HFC-134a used in small automobile air-conditioning. According to the previous work, HFC-161 has some excellent thermal physical characteristics. Theoretical cycle analysis was firstly developed to analyze the feasibility of replacing HFC-134a with HFC-161 at evaporation temperatures ranging from −5 °C to 10 °C, and condensation temperatures ranging from 50 °C to 65 °C. Based on the theoretical results, the experimental comparison of the cycle performance for HFC-161 and HFC-134a was conducted. The experiment was performed on a single-stage compression refrigeration system with a compressor designed for HFC-134a. In theory, the COPs of HFC-161 were quite close to those of HFC-407C; the specific refrigerating effects and volumetric refrigerating effects of HFC-161 were about 50% and 38% larger than those of HFC-134a, respectively. Experimental results showed that the COPs of HFC-161 were higher than those of HFC-134a at evaporation temperatures of −5 °C, 0 °C, 5 °C; the refrigeration capacities and compressor power consumptions of HFC-161 were about 56% and 47% larger than those of HFC-134a; the compressor discharge temperatures of HFC-161 were higher than that of HFC-134a by 20–35 °C. The experimental data agreed with the theoretical data. Considering the good environmental performance of HFC-161, it is highly significant to analyze the possibility of HFC-134a being substituted by HFC-161.
