Abstract:
Hybrid refrigeration machine is the machine with refrigeration principle and heat pump in one machine, so called the hybrid refrigeration vapor compression. Air conditioning and refrigerating industries weathered the phase out of chlorofluorocarbons (CHCs) and hydro chlorofluorocarbons (CHFCs), wich caused from the ozone layer depletion, by developments of hydro fluorocarbons (HFCs) as alternative refrigerants.however, the HFCs will also phase out because they are greenhouse gases as a cause of global warming. Therefore,natural substances, such as ammonia, hydrocarbons, carbon dioxide, are getting great interest. The research result is indicated that the use of mass HCR22 (hydrocarbon refrigerant os substitution R22) at hybrid refrigeration machine more economical 57.78% compared to R22 (halocarbon refrigerant) because HCR22 has the higher level of latent heat compared to R22. Cooling rate and heating by HCR22 compared of compressor use of HCR22 is more economical 25.12%compared to hybrid refrigerant can economize of electrical energy consumtion and environmental friendly
