Abstract

Cooling machines have a direct contribution to environmental damage including depletion of ozone layer and global warming caused by the leakage and discharge of synthetic refrigerants (HCFC and HFC) into environment. The discharge of refrigerant into the environment is 60 percent of service sector. Some obstacles found when making a model of a refrigerant waste treatment system since it could only be used for CFC (R-12)/ R-134a refrigerants. This research aims at redesigning a machine made beforehand thus it can process various refrigerant wastes used in hospitality industries which involved several components such as compressors, oil separators, filters and distillers for recycling R410A refrigerants. By having this ability, all refrigerant waste can be recycled. Result shows that the redesigned machine can recycle refrigerant waste and the signal can be reused. Calculation results on COP cooling system using pure R 410A showed 4.5, whereas by using recycled R 410A refrigerant 4.3 was obtained. COP using recycled refrigerants was lower than the one using pure refrigerants due to contamination of dirt, oil and other elements. However, with COP value of 4.3 the system performance is still good, therefore the recycled R410A refrigerant can be reused.
