针对重庆的特殊气候提出了具有水流层的双层玻璃温室的改进模型,并进行了测试分析.对双层玻璃温室进行了建模,得出了双层玻璃温室的两层玻璃间空气层厚度与温室玻璃厚度的比例,及空气层温差与温室玻璃的内外侧温差之比,并得出双层玻璃温室在持续高温且昼夜温差小的情况下隔热效果不明显.从而提出了模型改进方案,在一般的双层玻璃温室的外层内表面上定时喷洒一层水,形成一层薄薄的水流层,直接对玻璃温室的外层玻璃内侧进行降温,让部分热量得以转移,从而提高双层玻璃的隔热效果.通过模型分析和测试表明,具有水流层的双层玻璃温室隔热效果优于普通的双层玻璃温室.
Aiming at the special climate in Chongqing, an improved model of a double-glazed greenhouse with a water layer was proposed and tested. The double-glazed greenhouse was modeled and the air-layer thickness And the ratio of greenhouse glass thickness, and the temperature difference between the air layer and the inside and outside of the greenhouse glass ratio, and concluded that the double glass greenhouse in the sustained high temperature and small temperature difference between day and night insulation effect is insignificant.Then proposed model improvement program , A layer of water is regularly sprayed on the inner surface of the outer layer of the general double-layer glass greenhouse to form a thin layer of water flow, and the inside of the outer glass of the glass greenhouse is directly cooled down to allow part of the heat to be transferred, thereby increasing the double Through the analysis of the model and the test, it shows that the thermal insulation effect of the double glass greenhouse with the water layer is better than that of the ordinary double glass greenhouse.
