Shi Defu, Chen Hua, Zhou Chu. The Research on Heat Pump Air-conditioner with Condensing Heat Recovery[J]. Journal of refrigeration, 2013, 34(4). DOI: 10.3969/j.issn.0253-4339.2013.04.075.
A method integrating the condensing heat recovery technology with the heat pump technology to produce sanitary hot water was put forward. According to the characteristics of domestic air conditioner
the condensation heat was recovered and reused to heat the sanitary hot water. A prototype was set up for experiment which can achieve the function of heat pump water heater
heat pump air conditioner and condensing heat recovery. The system operating performance in simultaneously cooling and hot water supply was tested. The relationship among the quantity of hot water supplied
COP of the system and water temperature were discussed.
