EXPERIMENTAL RESEARCH ON THE OPERATIONAL CHARACTERISTICS OF HOUSEHOLD AIR-CONDITIONER WITH DOMESTIC HOT WATER SUPPLY

摘要

According to the operational characteristics of household air-conditioning system, the viewpoint of condenser heat recovery and reuse is proposed. A new kind of experimental household air conditioner with domestic hot water supply (HACDHWS) system is set up in our laboratory. The HACDHWS system can either work in air cooling operational mode or work in circulating water cooling operational mode. Experimental data and comparisons on the operational characteristics between the two modes are given in this paper. Some main analytical results are presented and the impacts of variation of water temperature on the performance of HACDHWS system are discussed in this paper. The result shows that the inherent performances of the household air-conditioning system is not obviously affected by water cooling and the EERC+w of the HACDHWS system is well achieved as long as the temperature of water in hot water storage tank is properly controlled. Both the system pattern and our research method have the unique characteristics.
