公共建筑集中空调系统过滤器选型方法优化

Optimization in selection of the filter for central air conditioning system in public buildings

为了满足集中空调建筑室内PM10平均质量浓度以及送风气流中PM10的质量浓度要求,利用质量守恒定律建立了一次回风空调系统过滤器选型数学模型。为了便于暖通设计人员进行选型计算,对所建立的数学模型进行了合理的简化,并给出了室外PM10质量浓度的确定方法以及室内发尘量的计算方法。

To meet the requirements of the average mass concentration of PM10 in indoor air and supply air,establishes a mathematical model for filter selection of the primary return air conditioning system according to the mass conservation law.In order to facilitate HVAC designing,simplifies the mathematical model,and gives the determination method of PM10 mass concentration in outdoor air and calculation methods of indoor dust production.
