摘要
本文对离心通风机在实际运行中的空气密度ρ的计算进行了分析。认为它不仅应考虑环境条件,同时还应考虑风机进、出口空气的温度。并提出了粮食加工厂通风机进、出口温度的计算方法和参考数值。
In the article , the method of calculating the p value of the air density of centrifugal ventilators in the process of actual running is analysed. The article regards that not only environmental conditions but also the air temperature of the entrance and exit of ventilators should be considered, and advances the method of calculation and the reference value of the temperature of the ventilator' s entrance and exit of grain processing factories.
