光伏墙内复合传热的实验与理论研究

Abstract

该文给出了对光伏墙内复合传热进行实验研究和数值模拟的结果。光伏墙是样品墙 ,由两块BP光伏板和泡沫塑料板组成。在室内辐照灯光下 ,光伏墙将部分光能转换为电能。通过实验 ,研究了光伏墙伴有隔热时的光电转换性能。为便于处理辐射散热 ,提出了一种温度积分模型用于数值模拟光伏墙内的复合传热。对比发现 ,考虑室内辐照灯的表面热辐射 ,可使模拟结果与实验结果吻合得较好。In this papers the results of experimental and theoretical investigation of combined heat transfer in a photovoltaic wall have been reported.The photovoltaic wall is a prototype wall which is composed of two pieces of BP PV Panels and a Styrofoam board, and a part of light of radiation energy from the indoor lamps can be converted into electricity. Through experiments,the performance of such a photovoltaic wall has been studied. For easy to treat heat radiation, a model of the integration of absolute temperature,has been proposed for the numerical simulation of the comlinted transfer in the test wall.By comparison,it is found that with regard to the thermal radiation of lamp surface, good agreement between the results of simulation and experiments is obtained.Department of Building Services Engineerin
