摘要： 采用集总参数法，将具有热水调温性能的被动式太阳能温室系统视为平板集热器，采用与家用太阳能热水器类似的试验方法，分析温室的热量平衡、热损失、平均传热系数，测试了实验温室的平均传热系数，占地45.09 m2的玻璃温室，地面为钢筋混凝土屋面，无土壤和作物影响，平均传热系数为5.3 W/(m2?℃)，对温室热性能分析和热水增温设计有一定参考意义和实用价值。

Abstract: Using lumped parameter technique, a passive solar greenhouse with hot water system to adjust the warm performance was regarded as the plate collector.Using the similar test method to determine the thermal performance of domestic solar heaters, the greenhouse heat balance and heat loss and average heat transfer coefficient had analyzed. In view of a greenhouse, the average heat transfer coefficient was tested and calculated. The results showed that the glass greenhouse, covering an area of 45.09 m2 ground for reinforced concrete roof, without soil and crop, the average heat transfer coefficient was 5.3 W/(m2?℃). It has a reference and the practical value to the greenhouse thermal properties analysis.
