摘　　要：提出一种基于微通道板强化换热的多功能百叶集热墙,在集热墙的空气夹层中构建百叶型微通道板,利用水循环带走积蓄在集热腔内部的热量,缓解夏季集热墙过热问题的同时可满足家庭对热水的需求。对比测试表明,多功能集热墙的背板温度相比于传统集热墙最高降低24.4%,而水箱平均水温最高达到46.80℃。该研究证明百叶集热墙在减少室内夏季得热、提供生活热水等方面均具有良好的实践效果。A traditional trombe wall has the problems of single purpose and temperature-high in summer which affects human comfort and increases energy consumption of air conditioning. This study puts forward a kind of multi-function trombe wall,which means that the venetian blinds made from several paralleled microchannel plates are installed in the air gap of the trombe wall. Water is circulated in the microchannel to take away excessive heat in hot summer. which can not only alleviate the problem of overheat in summer and but also generate the domestic hot water at the same time. The experimental results show that the temperature of the back plate of the multifunction trombe wall is 24.4% lower than that of the traditional trombe wall,and the average water temperature in the water tank reached 46.80 ℃. Therefore,the multi-function trombe wall can utilize the solar energy efficiently because of supplying hot water and simultaneously reducing overheat in summer.
