摘要

本研究认为R161具有优异的环境特性和热力学性能，可以作为R407C在小型空调系统中的直接替代品。为了研究R161在小型空调中的应用潜力，本文比较了R161和R407C在不同工况下的理论和实验循环性能，实验结果与理论结果具有良好的一致性，与采用R407C相比，采用R161时制冷系统的COP高约15%，压缩机功耗低约18%，排气温度低约（0～4）℃。为进一步分析采用R161的制冷系统在节能方面的潜力，基于气象数据和循环性能分析结果，对北京、上海、香港地区如采用R161的小型分体式空调系统年耗电量进行了能耗分析，分析表明，采用R161的系统年耗电量比采用R407C的系统年耗电量可降低约19.5%。总体而言，本文研究结果表明，R161 具有更好的循环性能，且与采用 R407C的现有小型空调系统具有良好的系统兼容性。

Abstract

In this work, with excellent environmental characteristics and thermodynamic properties, R161 is considered as a drop-in replacement of R407C used in small-scale air conditioning systems. In order to study the potential of R161 in the application, the theoretical and experimental cycle performances of R161 and R407C were compared under different working conditions. The experimental results agreed well with theoretical results. In the experiment, COPs of R161 were about 15% higher than those of R407C. The compressor power consumptions of R161 were about 18% lower than those of R407C. The discharge temperatures of R161 were about 0–4°C lower than those of R407C. Besides, the annual electric consumption of a small-scale split air conditioning in Beijing, Shanghai and Hongkong could be reduced by about 19.5%, when the working fluid was changed from R407C to R161. Overall, the results indicated that R161 has a better cycle performance and good compatibility with the existing systems designed for R407C.

Key words： R161; R407C; drop-in replacement; small-scale air conditioning system
