分段卷放保温被对日光温室光热效应的影响

Effect of sectionally rolling heat preservation quilt on light and heat effect in solar greenhouse

为减少温室热量损失,以阿克苏地区日光温室为研究对象,根据新疆实际情况,设计分段式日光温室保温被揭盖方式,通过连续观测温室内光照强度与空气温度变化,证实分段式保温被揭盖比一次性全揭开方式使温室前、后部气温平均值分别提高0.6℃和0.8℃,白天可使温室气温增温速率更快,降温速率更慢。在阴天可以增高温室内后部的光照强度;因此分段卷放保温被可以有效提升新疆日光温室性能,增强温室保温蓄热能力。

In order to reduce the greenhouse heat loss,the Aksu area solar greenhouse as a research object,according to the actual situation in Xinjiang,the way of taking off the heat preservation quilt in sectional solar greenhouse was designed.By continuously observing the changes of light intensity and air temperature in the greenhouse,it is confirmed that the average temperature in the front and back of the greenhouse was increased by 0.6 and 0.8 ℃ respectively by taking off the heat preservation cover of the segmented solar greenhouse compared with the way of taking off the heat preservation cover all at one time.In the daytime,the temperature in the greenhouse increased faster and decreased slower.The light intensity in the rear part of the greenhouse can be increased in a typical cloudy day;Therefore,the sectional rolling heat preservation quilt can effectively improve the performance of the sunlight greenhouse in Xinjiang and enhance the heat preservation and heat storage capacity of the greenhouse.
