The global sustainability of HFCs like R-134A requires a focus by the HVAC industry on the real environmental issues of refrigerant containment and energy efficiency. By committing to the design of more energy-efficient systems using these refrigerants, the industry will significantly improve the environmental impact of refrigeration and air conditioning products. Cold room is refrigerated space where low temperatures maintain for preservation of dairy products & Food. The cold room is designed with refrigeration capacity 1.3 TR. During retrofit refrigerant procedure, design these system various design parameter like cooling load calculation, selection of compressor, thermostatic expansion valve, condenser capacity and piping design are considered. as well as the change of lubricant in the compressor also considered.

low GWP, zero ODP, retrofits, glycol solution
