摘　　要：详细分析和总结了国内外自然工质R290制冷空调系统的应用与研究现状。R290单位容积制冷量大、价格低廉、臭氧消耗潜值为0,全球变暖潜值很小,热力性能与常规制冷剂相比有明显的优势。R290制冷空调系统结构紧凑,制冷剂的充灌量少,金属材料的消耗少,设备的初投资少。随着R290应用技术研究的不断深入,环保制冷剂R290将拥有广阔的市场应用前景,在未来制冷空调系统中将显示出巨大的优越性。The application and investigation of natural refrigerant R290 refrigeration and air-conditioning system was intro- duced. R290 has larger volumetric capacity, lower cost, and it naturally exists in the atmosphere and has neither ozone depletion potential nor significant global warming potential. It has excellent thermodynamic performance as refrigerant compared with con- ventional refrigerants. The R290 refrigeration and air-conditioning system has smaller size; so as to decrease the charge of refrig- erant, save the material of metal, reduce the cost of equipment With the progress of the study on the R290 practical application technology, R290 has a good future used as refrigerant in refrigeration and air-conditioning system.
