利用浅地表层所蓄太阳能改善室内热环境的埋管热过程研究

STUDY ON THERMAL PROCESS OF BURIED TUBE BENEATH THE EARTH SURFACE TO IMPROVE THE INDOOR THERMAL ENVIRONMENT

讨论了一种利用浅地表层蓄存的太阳能改善室内热环境的方法，建立了埋管冷却或加热空气的热过程数学模型，通过理论分析、数值模拟和实验测试较系统地揭示了热过程规律。结果表明，利用受太阳辐射影响较大的浅地表层蓄能改善室内热环境是可行的。

n this paper, a method of using solar energy stored in the earth beneath surface to improve the indoor thermal environment. is presented and a mathematical model for the thermal process of buried tubes to cool or heat air is given as well. The regularity of this thermal process is analysed with some theoretical analysis, numerical simulation and site test.
