| Abstract: | R134a is a long-term green alternative refrigerant with zero ODP（ozone-depleting-potential） to replace R12.By comparing the nature of the R134a with R12,the paper mainly introduces how to change the corresponding structure of the system,involving compressor,condenser,evaporator and expansion valve,so as to optimize the air conditioning system. |
