摘　　要：本文主要针对CFC11、CFC12以及HCFC22介绍了目前替代工质的发展现状,阐述了混合工质以及氨、二氧化碳、碳氢化合物等自然工质作为替代工质的特点以及其发展现状,总结了制冷空调系统替代工质的发展方向。The state of substitute refrigerants for CFCll, CFC12 and HCFC22 in present has been described. The feature and the development state of hybrid refrigerants and natural refrigerants such as ammonia, carbon dioxide and hydrocarbon used for substitute refrigerants for freon have been discussed. The development trend of substitute refrigerants in refrigeration and air conditioning system has been concluded.
