| 摘 要： | 针对宁夏二代日光温室和引进的山东五代日光温室进行传热特性分析,得出无论从晴、阴天还是从长季节观测分析,山东五代日光温室的墙体放热量均极显著大于宁夏二代温室的墙体放热量;山东五代日光温室的地面放热量显著小于宁夏二代温室的地面放热量;通过计算整个冬季的墙、地放热总量可知,山东五代日光温室的墙、地放热总量比宁夏二代日光温室的墙、地放热总量高9.9%。并且以整个长季节观测数据为基础,计算得到了两种类型日光温室的墙体与地面对温室热量的贡献率,在整个冬季,宁夏二代温室的墙体放热量低于地面放热量2%,山东五代温室的墙体放热量高于地面放热量34%。

| Abstract: | The study observed heat release of soil back wall and ground of solar greenhouse,and measured surface heat flux of soil back wall both in sunny days and cloudy days in Shangdong-5(sd-5) and Ningxia-2(nx-2) greenhouses.The result showed that sd-5 greenhouse's heat release of per unit wall area is significant greater than nx-2 greenhouse's,and sd-5 greenhouse's ground surface heat release of per unit ground area is less than nx-2 greenhouse's,no matter in short time or long term.The sd-5 greenhouse's total am... |
