摘 要:从臭氧层破坏和全球温室效应等角度出发,通过对工质替代的意义较全面的分析,提出了替代工质的筛选原则,并建立制冷剂综合性能评价指标体系,同时分析适用于地源热泵的HFC替代工质.According to Montreal Protocol Amendment, refrigerants R-22 still used in air conditioning systems will be universally banned by 2030 for their ozonosphere depletion and global greenhouse effect. Hence, research on refrigerant alternative for GSHP units is too urgent to be delay. Through analysis of the meaning and prospect of refrigerant alternative, the filtrating principle of refrigerant alternative is put forward, and index system of evaluation to performance of alternative refrigerants is dealt with, and finally several ideal alternative refrigerants for GSHP units are analyzed.
