PENGGUNAAN ENCAPSULATED ICE THERMAL ENERGY STORAGE PADA RESIDENTIAL AIR CONDITIONING MENGGUNAKAN REFRIGERAN HIDROKARBON SUBSTITUSI R22 YANG RAMAH LINGKUNGAN

Residential Air Conditioning is the wide option used to get the cool and comfortable in house. Improvement usage of AC caused by the good recovery of economics and the good range of price AC for residential achieved, especially for the family from middle to up level. Escalation usage of AC in the residential caused by increase the environmental air temperature heat as effect of climate change (global warming). Usage of AC for house or residential consume the electricity 45% - 66 % from totalizing usage of electricity for house or residential, so that most expense of electricity invoice used to pay for the freshness which obtainable. Usage of Encapsulated Ice Thermal Energy Storage at Residential AC system can economize the use of electricity 20% - 60%, this matter because the using compressor most replaced by pump to distribute the chilled fluid. Electricity cost-saving also can be improved with the use of hydrocarbon refrigerant as substitution of R-22 refrigerant, which can economize the usage of electricity 10% - 20%. Can concluded that usage of Encapsulated Ice Thermal Energy Storage at Residential Air Conditioning of vapor compression refrigeration machine with hydrocarbon refrigerant as Substitution R22 refrigerant can cost economize that required to get the comfortable room to various use condition
