Heat Transfer Mechanism on the Enclosing Walls and the Soil of the Chinese Solar Greenhouse with Different Spans in the Slope Land of Northern China
In this experiment, variations of heat flux on enclosing walls (south roof, side walls, north wall and back slope) and soil in the solar greenhouses with different spans (8.0m, 9.0m, 9.5m and 10.0m) which were built in Chifeng, Inner Mongolia Autonomous Region were studied in winter. It showed that the north wall and soil were main heat storing and emitting bodies; about 70% and 25% of the whole heat energy were released by the north wall and soil respectively. Due to the heat storage of the hill, the amount of heat absorption on the north wall and soil was smaller than the amount of heat emission. In the experimental conditions, the increase of span helps to improve the heat accumulation at daytime and energy release at night, and among the tested spans, the 10.0m span was the optimal structure for the solar greenhouse.
