PERFORMANCE STUDY ON A SOLAR HYBRID AIR-CONDITIONING SYSTEM FOR RESIDENTIAL WATER HEATING

This paper describes an experimental study of using the waste heat from a Panasonic Under Ceiling split room air - conditioner had a rated capacity of 3.51 kW (12,000 Btu/h). An under – ceiling split type air conditioning for heating domestic water in private homes. Energy recovery improved the performance, and the recovered energy could replace electricity completely for heating domestic water use. An extra charge of refrigerant in the air-conditioner could prevent its compressor from overheating during energy recovery. The experimental conducted on varies capacity of the range from 22.5 liters to 120 liters storage tank. Results show the water temperature increased lies in the range of 50 OC to 65 OC. It was found that, when the initial water temperature in the 22.5 liters storage tank 27 OC, the water temperature reached 65 OC in 105 minutes. For 120 liters water, temperature increased from 27 OC to 62 OC, in 240 minutes.
