Studies of Floor Heating and Hot Water Supply Using a Heat Pump that Adopts Solar Thermal and Photovoltaic Hybrid Panel and Air Refrigerant Heat Exchanger

对铝合金压焊平板（蒸发器）与空气-制冷剂换热器或翅片管集热器联用的热泵系统的特性进行了实验研究和理论分析。据发现，使用面板和串联布置的其他空气-制冷剂热交换器中的一个对于获得热泵的高COP是有用的。热泵系统可将循环水加热到30 ~ 35℃，用于地板采暖。分析结果与实验结果吻合较好。针对某住宅的房间供暖和热水供应，采用太阳能热泵对安装在水箱下的循环水进行加热，构成空调与地板供暖的组合系统。在30 ~ 350℃时，管内水产生约300 W的功率，使地板温度比22℃时的室温高2 ~ 3℃。在实验中，太阳能集热器的收集是通过使用平板太阳能集热器。两个总面积为4m^2的收集器是合适的。在白天，水箱中的水温达到26℃。然后，夜间不供暖，清晨环境气温为0℃时，地板温度变为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℃.
