对铝辊粘接平板（蒸发器）与空气冷媒换热器或翅片管集热器组合使用的热泵特性进行了实验和分析研究。结果表明，采用板式换热器与其他空气-冷媒换热器中的一种串联布置，有利于获得热泵的高COP。热泵系统适用于加热30 ~ 35℃的循环水用于地板采暖。分析结果与实验结果吻合较好。对于房屋的房间供暖和热水供应，空调和地板采暖系统的组合使用，该系统由太阳能热泵组成，向安装在水箱下方的管道中的循环水提供热量。管内的水在30 ~ 350℃时产生约300W，在22℃时地板温度比室温高2 ~ 3℃。在实验中，利用平板太阳能集热器收集太阳热量。2个收集器，总面积为4m^2为宜。白天，水箱里的水温达到26℃。然后，在夜间不采暖的情况下，当周围空气温度为0℃时，清晨地板温度为15℃。

The characteristics of the heat pump using aluminum roll-bond flat panels (evaporator) together with an air-refrigerant heat exchanger or a finned tube collector was studied experimentally and analytically. It was found that the use of the panels and one of the other air-refrigerant heat exchangers arranged in series is useful to obtain high COP of the heat pump. The heat pump system is useful to heat the circulating water at 30〜35℃ for the floor heating. The analytical results agreed well with the experimental results.For room heating of a house and hot water supply, a combined use of an air-conditioner and floor heating system that was composed of a solar boosted heat pump to supply heat to the circulating water in a tube installed under the water tanks. The water in the tube at 30〜350℃ produced about 300W with which the floor temperature became 2 to 3℃ above the room temperature at 22℃. In the experiment, the collection of solar heat was made by using flat-plate solar collectors. Two collectors with total area of 4m^2 was appropriate. During the daytime, the temperature of the water in the tanks reached to 26℃. Then, without heating during the night, the floor temperature in the early morning became 15℃ when the ambient air temperature was 0℃.
