Performance of a heat pump using hydrocarbon refrigerants are experimentally investigated. The working fluids for this study are R-290(propane), R-600a(iso-butane) as a natural refrigerant and HCFCs refrigerant R-22. The experimental apparatus is a conventional vapor compression type heat pump system. The performance of each refrigerant are obtained under several compressor speeds and the change temperature levels of secondary heat transfer fluids. The compressor work increased as the evaporating temperature increased and were a little higher using hydrocarbon refrigerant than HCFCs refrigerant. The increasement of refrigeration capacity with hydrocarbon refrigerant were better than R-22 according to the evaporating temperature. And COP increased linearly as evaporating temperature increased and showed the highest value when R-600a(iso-butane) was used as a working fluid. Experimental results showed some hydrocarbon refrigerants had better characteristics than R-22, that is, the natural refrigerants can be used as substitute for R-22.<br/> <br/>
