摘要
根据公共建筑室内PM2.5污染来源、运动规律,结合室内PM2.5污染控制通风过滤模型,分析了通风换气对降低室内PM2.5污染浓度的影响,给出了空气过滤器过滤效率计算公式及简化选型计算公式,提供了室内PM2.5浓度控制标准要求,结合目前常见的集中空调系统空气过滤器配置工况,通过实例计算,给出了集中空调系统空气过滤器等级组合建议。
Based on the source ofindoor and outdoor PM2.5 pollution in public buildings and its law of motion as well as the ventilation and filtering model for indoor PM2.5 pollution control, the influence of ventilation and air change on the decrease of indoor PM2.5 concentration was analyzed, the calculation formula of efficiency of air filter and the calculation formula for simplification and model selection were provided, and the criteria for indoor PM2.5 concentration control was prepared. By referring to common working condition of air filter of central air-conditioning system, the combination of grade of air filter of central air-conditioning system was recommended in an example.
