| 摘 要： | 提出一种新型的PV/T蒸发屋面被,该屋面除具有防水、美观等基本功能外,还兼作PV/T热泵系统的蒸发器,集发电、制热于一体。通过实验,详细分析夏季工况下PV/T屋面各层的温度分布、空腔中流体的流动特性,并探讨PV/T屋面的设置对建筑外表面温度及建筑得热量的影响。结果表明;夏季热泵系统运行时,PV/T屋面系统中腔体内流体被加热,较普通屋面而言,其原屋面外表面温度降低,最高降低21℃,但夜间时略高于普通屋面1℃,总体而言,PV/T屋面的设置使建筑得热量降低44%。

| Abstract: | A novel PV/T roof is presented,which has the basic function such as waterproof,beautiful,and for evaporator of PV/T heat pump system,successfully integrating power generation and heating. In this work,temperature distribution of the PV/T roof and air flow characteristic in the cavity in summer were comprehensively analyzed by experiments,and the effects of the PV/T roof on external surface temperature of the original roof and building energy consumption were elaborated. The results showed that the fluid in the cavity of PV/T roof system is heated as the heat pump system operating in summer. In contrast to the ordinary roof,the external surface temperature of the original roof in PV/T system is reduced around 21 ℃ at the highest in the daytime,while slightly higher than the ordinary roof 1 ℃ at night. In general,the set of PV/T roof reduces the building heat gains by 44%. |
