Experimental Investigation of Performance of Conventional Vapor Compression Refrigeration Cycle Using Geothermal Cooling in Extreme Hot Weather Conditions

The well-known traditional vapor compression refrigeration cycle is considered to be the most effective technique used in field of and air-conditioning systems. It’s almost every facility including industrials, homes food storages. There are some environmental hazards concerning use vapor-compression cycles such as global warming ozone layer depletion mainly due refrigerant's leakages. However, it's still a leading technology for its capability producing high cooling heating powers with great coefficient performance. present work represents an experimental investigation effect condenser's temperature on thermal performance conventional cycle. geothermal was introduced utilized condenser that operates harsh climate conditions. experiment performed using two additional heat exchangers enabling exchange temperature. first exchanger (primary HX1) connected directly while other one (secondary HX2) installed inside hole intended These (HX1 were thermally via PVC tubes straight water circulating them (using DC pump). results proved success current method improving system. Cooling has led considerable reduction refrigerant improved overall apparatus showed increase both capacity COP by 25% 21.5%, respectively. In addition, enhancement evaporator accomplished reach minimum 14.5ºC.
