摘　　要：针对温室加温能耗大的突出问题，设计了双层覆盖温室地下蓄热系统。测试了冬季夜间保温时温室内外温度、湿度，计算了达到同样环境温度时燃煤热水锅炉加温所需能耗及燃料成本。结果表明，在冬季白昼为晴天、多云、阴天时，双层覆盖温室地下蓄热系统蓄热后，夜间保温时温室内温度分别高于外界温度5．1～9．8℃、4．8～6．9℃、4．2～6.4℃，室内外平均温差分别为6．9℃、5．4℃、5．3℃，其能耗费用低于燃煤热水锅炉加温费用，系统具有良好的保温性能，节能效果明显。In order to reduce energy consumption in greenhouse, the underground heat storage system with double-film covering was designed based on the plant physiology. The temperature and humidity inside and outside greenhouse were measured during heat conservation at night. At the same time, the energy consumption and the fuel cost of the coal fired hot water boiler were calculated when the temperature in greenhouse reach the temperature measured above. It was indicated that the inside temperature were 5.1-9.8℃ ,4. 8-6.9℃ ,4.2-6.4℃ higher than the outside temperature respectively and the average temperature difference between inside and outside greenhouse were 6.9 ℃, 5.4℃, 5.3℃ during heat conservation at night after heat storage in the clear day, cloudy sky and over cloudy sky in winter. Moreover, the energy consumption cost was less than the heating cost of the coal-fired hot water boiler. So the heat conservation and energy saving of the system is significant.
