摘要(Abstract)：

通过对R290与其它几种家用空调制冷剂的热力性能分析与比较,得出R290具有良好的热力性能,其物理性质与R22极其相近,属于直接替代物。开发R290家用空调,对环境保护、节约能源有着很好的应用前景。
This paper focuses on the domestic air-conditioning using the natural refrigerant R290.The good thermodynamic performances of R290 are demonstrated by comparing R290 with other refrigerants.The physical properties of R290 are similar to that of R22,so R290 can replace R22 refrigerant directly.Study on practical application of R290 in domestic air-conditioning has a good future for protecting environment and saving energy.
