Performance of HCFC-22 alternative natural refrigerants for air-conditioning and heat-pumping applications.

Author(s) : JUNG D. S., HAM Y.

Summary

In this study, performance of 2 pure hydrocarbons and 7 mixtures has been measured in an attempt to substitute HCFC-22. The mixtures were composed of propylene (R1270), propane (R290), HFC-152a, and dimethylether (RE170, DME). The pure and mixed refrigerants tested have GWPs of 3-58 as compared to that of CO2 and the mixtures are all near-azeotropic showing the gliding temperature difference of less than 0.6°C. Thermodynamic cycle analysis was carried out to determine the optimum compositions and actual tests were performed in a breadboard type laboratory heat pump/air conditioner at the evaporation and condensation temperatures of 7 and 45°C respectively.
