摘　　要：对建造在南宁市西郊的一座被动式太阳房在夏季运行时的实验数据进行了分析,其屋顶集热表面在夏季夜间能产生一定的致冷效果。所制取的冷空气不但在夜间可以对该太阳房起到降温的作用,并且可以储藏起来以供白天降温使用。The passive solar house is in general used for heating in winter.It was considered to be impractical that the passive solar house could be warm in winter and cool in summer.In this paper,the principle of operation of Nanning Solar House and radiation cooling were depicted.An experimental investigation on passive cooling of solar house was conducted to verify the passive cooling effect.The experimental results show that radiation cooling via col-lecting plates of the solar house is feasible in theory and practice.By radiation cooling a certain amount of cool air is produced during nighttime,which can be used for reducing the temperature in the solar house.The cool air can be put in storage for cooling during daytime as well.
