Abstract
This study of the performance characteristics of natural refrigerants such as R-290 (propane), R-6OOa (iso-butane) and R-1270 (propylene) has investigated to compare with conventional HCFC's refrigerant R-22 for water-cooled heat pump system. The experimental apparatus has basic parts of cycle that uses the water as a heat source. The Performance of the water-cooled system using hydrocarbon refrigerants had been getting better than R-22 from start-up to the similar evaporating temperature after stabilizing system. Through the above it is possible that hydrocarbon refrigerants could be drop-in alternatives for R-22.
