带热水供应的家用空调器运行特性研究

针对家用空调的特点,提出了对家用空调冷凝热进行回收利用的观点,利用热回收系统加热生活用水,并建立了一种新型的带热水供应的家用空调试验系统。通过该试验系统各测点的试验数据,对该设备在空冷运行模式和水冷热回收运行模式两种情况下的运行特性作了相应的分析,给出了一些重要参数的实验结果,并分析讨论了在热回收时水温变化对系统的影响。结果表明,制冷和制热同时协调运行时,不仅不影响机组原有的性能,并且在制冷和提供生活热水的同时,提高了系统的总能效比,达到节能环保的目的。

Research on the operational characteristics of household air- conditioner with domestic hot water supply

The viewpoint of condenser heat recovery and reuse is proposed by according to the technical characteristics of household air-conditioning system.The heat recovery system can be widely used for domestic hot water supply.A household air conditioner with domestic hot water supply(HACDHWS) system is set up in our laboratory.The HACDHWS system can work in air cooling operation mode and in circulating water cooling operation mode.Experimental data are shown.Corresponding analysis and comparisons of the operational characteristics between the two modes are given in this paper.Some main parameters results are presented and the impacts of variation in water temperature on the HACDHWS system performances are discussed in this paper.The result shows that the original performances of the household air-conditioning system is not obvious affected and the EERC w of the HACDHWS system is improved as long as the temperature of domestic hot water supply in water tank for storing heat is properly controlled.
