强制通风温室中温度分布的试验研究

A Experimental Study on Temperature Distribution in A Forced Ventilated

本文介绍了在强制通风温室中使用水帘和不使用水帘降温时,不同通风率情况下温室温度分布,包括室内外温差、温室长度方向和高度方向温度差的试验测试方法。试验结果表明:在不使用水帘和使用水帘时;温室内温度差在垂直方向最为显著,增大通风率会减少该温度差;与不使用水帘相比,使用水帘时提高通风率对降低室内温度效果显著。

This paper introduces an experiment on measuring temperature distributions including temperature difference between inside and outside of greenhouse, temperature distributions along greenhouse and vertical direction of a forced ventilated greenhouse. The comparisons also were made between two ventilation rates and between with and without pad cooling. The experimental results show that in both cases of with pad and without pad a strong temperature difference exits in vertical direction of greenhouse and this difference can be reduced with increased ventilation rate.
