Abstract

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 multi-function 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.
