下沉式日光温室土质墙体的保温蓄热性能

Experimental research on cob wall's insulation and heat preservation performance of sunken greenhouse

为研究土质墙体下沉式日光温室的保温蓄热性能,对墙体温度及热流的变化进行了实验测试。测试结果表明:白天土质墙体接受太阳辐射并蓄热;夜间墙体内侧表面温度高于室内温度,墙体向室内放热。土质墙体具有良好的保温蓄热性能,可以满足作物生长的需要,。

The application of sunken greenhouse with cob wall spreads wider to study the heat preservation performance of the cob wall, this paper explains the experiments on its temperature and heat flux. The results show that： the cob wall absorbs solar radiation and stores up heat in the daytime and could release the heat when the temperature of the wall inner surface is higher than indoor temperature at night. The indoor temperature all day can guarantee the normal crop The cob wall has well insulation and heat preservation function.
