摘要
防虫网显著增大温室通风系统阻力,但迄今缺少对其定量的测定数据。该文测试并分析了不同网孔密度的防虫网在不同气流速度下的局部通风阻力特性,并通过回归分析得到了几类计算防虫网的阻力经验公式,给出了它们的阻力系数计算取值的建议,可供温室通风设计计算中使用参考。
Insect-proof screens can distintly increase the resistance of the greenhouse ventilation systems, but now people are short of the test information. In this paper, the resistance of some different density insect-proof screens under different wind velocities were experimented and analyzed, and the resistance equations of which were regressed. In the last of the paper, the authors gave some suggestions on selecting of insect-proof screens resistance coefficient, which can provide references for the greenhouse ventilation design.
