摘要(Abstract)：
R32具有良好的热物性、环境性能和循环性能,具有极大替代R410A工质的潜力。采用R32对R410A空调系统进行灌注式替代试验,研究结果表明,系统灌注R32后,制冷剂充注量减少了30.4%,制冷量提高了8.5%,性能系数提高了7.1%。
R32 has good thermophysical properties and friendly environmental performance,which make it as a potential refrigerant to R410A.In this study,R32 was poured into a household air conditioning designed for using R410A.The test results show that the optimum charging quantity of R32 is about 30.4% of the original charging quantity of R410A,and the refrigeration capacity can increase 8.5% of the R22 system and the EER can increase by up to 7.1%.
