不同墙体结构日光温室性能测试及分析

Performance test and analysis of solar greenhouse with different wall structures

为提高日光温室冬季保温蓄热的能力,同时推动日光温室的快速建造,设计3种新型墙体结构的日光温室:相变固化土主动蓄热温室(G2)、模块化素土主动蓄热温室(G3)、现浇混凝土被动蓄热日光温室(G4)。测定3种温室室内环境,以传统主动蓄热温室(G1)为对照温室进行对比分析。结果表明:4种温室在典型晴天条件下夜间的平均温度分别为15.7、16.4、17.8、16.6℃;在典型阴天情况下夜间的平均温度分别为12.4、13.8、13.8、13.1℃;在连续雪天情况下最低平均温度分别为7.3、8.3、8.8、7.8℃。G3即模块化素土主动蓄热温室在夜间和连续低温条件下都表现出了较好的保温性能,能够在室外温度较低时给室内作物提供更好的生长环境,且建造方便,在适宜日光温室发展的地区具有一定的推广价值。

In order to improve the heat preservation and heat storage capacity of solar greenhouse in winter and promote the rapid construction of the solar greenhouse,three types of solar greenhouses with new wall structures were designed,namely Phase change solidified active heat storage greenhouse (G2),Modular soil active thermal storage greenhouse(G3) and In-situ concrete passive heat storage solar greenhouse(G4).They were measured for the indoor environment and compared with Traditional active heat storage greenhouse (G1) as the control.The test results of the four types of greenhouse showed that the average nighttime temperatures under sunny conditions were 15.7,16.4,17.8 and 16.6 ℃,respectively;The average nighttime temperatures of cloudy days were 12.4,13.8,13.8 and 13.1 ℃,respectively;The lowest average temperatures under continuous snow conditions were 7.3,8.3,8.8 and 7.8 ℃,respectively.G3,the Modular soil active thermal storage greenhouse,showed good performance at night and continuous low temperature conditions,which provided a better growing environment for indoor crops when the outdoor temperature was low,was convenient to construct,and had certain promotion value in areas suitable for solar greenhouse development.
