Abstract    In accordance with the international agreements, pollutant refrigerants R-22 and R134a are to be phased out because of their environmental concerns like depletion of ozone layer and rise global warming. Many refrigerant options have been tried to replace R22 and R134a for different applications. The water cooler is one of the applications widely used in which R22 and R134a refrigerants are presently used. This study suggests that environment friendly refrigerant R290 is the best option as a replacement for R22 and R134a refrigerant for water cooler applications. A breadboard type laboratory water cooler of a nominal capacity 1.5 kW is especially designed, developed for R290 and its performance is investigated experimentally for different operating conditions. Performance parameters like cooling capacity, discharge temperature and coefficient of performance are analysed. Experimental results showed that compressor energy consumption, discharge temperatures are lower for the water cooler refrigeration system. The overall performance of the especially developed system for water cooler application proved that R290 can be a better alternative refrigerant with respect to energy efficiency and greenhouse impact as a replacement to R22 and R134a in tropical countries.
