This paper analyses the thermodynamics properties of major CFCs alternative refrigerants,present the modifications with the R12 refrigerator for compressors when it is converted to CFCs alternative refrigerants,and compare the advantage & disadvantage and difference & commonness of various refrigerants.

The technical strategy that is suitable for current CFCs replacement in small and medium-sized enterprises of domestic refrigerator and freezer in China is presented.

Based on sustainable development,CO_2 emerges as one of the most likely alternatives to the synthetic fluids in heat pump water heaters.

This paper discusses a simple method which is able to provide the COP and the capacity of a theoretical refrigerating cycle using alternatives as working fluids, by means of some new relative factors such as the reduced difference of the cycle temperature, the reduced suction temperature and subcooling temperature.

Experimental study on performance of air source heat pumps with alternative refrigerants;

In this paper, experimental studies are carried out on the suitability of alternative refrigerants of R32/R134a and R407C with polyester type lubricants of different models.

The refrigerator performance tests have been carried out using refrigerant CFC12 and its alternative refrigerant HFC152a/HCFC22.
