NUMERICAL AND EXPERIMENTAL STUDY ON THE PERFORMANCE OF A SPLIT AIR CONDITIONER WITH HOT WATER SUPPLY IN THE COOLING AND WATER-HEATING MODE
The recovery of condenser heat in air conditioners is attractive because of its great economical and environmental value. It is significant to predict system performance in order to develop the correlative air- conditioning product. In the paper, this work studies a split air conditioner with hot water supply in the cooling and water-heating mode by numerical simulation and experimental test. Its dynamic operation characteristics, energy efficiency and the temperature distribution of hot water in the storage tank are analyzed. The results indicate that the effect of stored hot water temperature has a great influence on operation performance of the unit without the air-cooled condenser. However, the device can reliably be used to heat domestic hot water without losing its cooling capacity when the air-cooled condenser is controlled well in different operation conditions. Comparatively, the coefficient of cooling performance (COPc ) and the coefficient of comprehensive energy performance (COPcw) of the unit are respectively about 10％ and 52.4％ higher than that of the original in the same condition. Furthermore, all these may be much helpful to develop a perfect product of air conditioner with hot water supply.
