R32与R410A家用空调器性能对比分析

Performance study of R32 and R410A in Household Air Conditioners

根据中国2030年“碳达峰”与2060年“碳中和”的整体目标,制冷空调产业制冷剂的更替速度不断加快。R32作为R410A的一种过渡性替代制冷剂,已经逐步在家用空调系统推广使用。采用实验研究的方法,采用搭配Φ5mm蒸发器的同一家用空调系统,分别采用R32和R410A作为制冷剂,在7种不同工况下对空调系统的性能进行了测试。实验分析结果表明:R32可以在不改变空调系统结构的前提下直接替代R410A;且R32系统制冷(热)能力、能效比均高于R410A;R32系统排气温度略高于R410A,且全年能源消耗率也高于R410A。研究结果为R32在家用空调系统中的更进一步推广应用奠定了良好的基础。

According to the overall target of "carbon peak" in 2030 and "carbon neutral" in 2060, the replacement of refrigerants in the refrigeration and air-conditioning industry has been accelerating. The use of R32 as a transitional replacement refrigerant for R410A has been gradually promoted in domestic air-conditioning systems. In this paper, the performance of the same domestic air-conditioning system with Φ 5mm evaporator was tested under seven different working conditions using R32 and R410A as refrigerants. The experimental analysis results show that R32 can directly replace R410A without changing the structure of air conditioning system, and the cooling(heating) capacity and energy efficiency ratio of R32 system are higher than those of R410A;the exhaust temperature of R32 system is slightly higher than that of R410A, and the annual energy consumption rate is also higher than that of R410A. The research results lay a good foundation for the further promotion and application of R32 in domestic air conditioning system. The results of the study lay a good foundation for further application of R32 in domestic air conditioning systems.
