新型光伏直膨式太阳能/空气能多能互补热泵性能

以平板热管（微热管阵列）为核心部件，设计了一种新型太阳能光伏/空气集热蒸发器并建立了光伏直膨式太阳能/空气能多能互补热泵系统，实现全年供热水、冬季供热、夏季供冷以及全年光伏发电的功能。对北京地区3月至5月天气条件下的热泵系统性能进行不同运行模式（S、SA以及A模式）的实验研究。实验结果表明，在典型工况下S、SA与A模式的多能互补系统COP_s分别为4.8、4.2与3.8，综合效率分别为109.7%、125.9%、32.4%，即在有太阳辐照的条件下，S与SA模式下多能互补系统性能优于A模式。该新型光伏直膨式太阳能/空气能多能互补热泵系统性能优良，研究结果为该系统应用提供了基础数据支撑。

Performance of direct-expansion photovoltaic/thermal(PV/T)-air source heat pump system

With flat heat pipe (micro-heat pipe array) as the core component, a new type of PV/T-air collecting evaporator and direct-expansion PV/T-air source heat pump system were designed and built to realize the functions of year-round water heating, winter heating, summer cooling and year-round photovoltaic power production. Experimental study on the performance of heat pump system under the weather conditions from March to May in Beijing was carried out in different operating models (S, SA and A).The experimental results show that the COP_S of model S, SA and A is 4.8, 4.2 and 3.8,the η of three models is 109.7%, 125.9% and 32.4% under typical working conditions, which means under the condition of solar irradiation, the performance of the multienergy complementary system in mode S and SA is better than that in mode A. The new heat pump system has a significant performance, and the experimental results provide basic data support for its application.
