摘　　要：为了研究不同工作条件下R22替代工质在空气源热泵热水器中所展现的不同系统性能,课题组利用单级压缩制热循环系统对其替代工质做了理论分析,经计算得出R134a和R407C的性能较为优异,但是考虑到2者具有较高的全球变暖潜能值,并不适合作为长期使用的工质,而R32与其他制冷剂相比,除却排气温度稍高的问题以外,其综合性能最佳。随着市场上有效降低压缩机排气温度的技术逐渐成熟,在空气源热泵热水器中,R32作为R22的替代制冷剂将具有很好的应用前景。According to different system performance under different working conditions of R22's alternative refrigerant in air source heat pump water heater,the theoretical analysis using single stage compression heat pump system,the results showed that the performance of R134 a and R407 C were more excellent. But considering the higher global warming potential,they were not suitable for long-term use as a refrigerant. In addition to the problem of slightly higher exhaust temperature,the overall performance of R32 was the best. With the development of the technology to effectively reduce the exhaust temperature of the compressor in the market,in the air source heat pump water heater,R32 refrigerant has a better application prospect than R22 refrigerant.
