Résumé

The paper presents an experimental study on the performance of hydrocarbon refrigerants, namely propane and a LPG mix as suitable replacements for the widely used HCFC-22 in refrigeration and heat pump applications. A cylinder of commercially available LPG from New Zealand market was obtained for this study. The composition of the specific LPG mix (by mass fraction) was propane (HC290): 98.95%, ethane (HC170): 1.007%, iso-butane (HC600a): 0.0397%, and other constituents in small porportions. Experiments were carried out in a laboratory heat pump test facility with maximum condenser capacity of approximately 15 kilowatts. Condensing temperatures were held constant at 35, 45 and 55 deg C, while evaporating temperatures were varied over a wide range from -15 to 15 deg C. All tests were carried out at constant degree of superheat (about 1 K) and subcooling (about 8 K). All appropriate precautions were observed against any leaks or fire.
