多模式通风净化器的性能模拟

Performance simulation of a multiple-mode ventilator for ventilation and air filtration

提出了一种具有多种使用模式的通风净化器,在其自然通风和机械通风通道中安装了不同净化效率的空气过滤器。为评估该通风净化器的性能,将不同操作模式下的阻力-流量特性和颗粒过滤性能引入到EnergyPlus中进行建模,模拟了通风净化器的风量和空气过滤效率,并通过实验数据进行了验证。使用该模型对通风净化器在不同气候区典型房间的空气品质和能耗进行模拟,结果显示在满足室内空气品质的前提下,通风净化器较现有高效新风机可降低高效净化模式70%左右的使用时长,单位面积年通风净化能耗降低约30%。

Proposes a ventilator with multiple modes of air filtration,and installs different efficiencies of air filters into the natural and mechanical ventilation ducts respectively.To evaluate the performance of the ventilator,establishes a model in the EnergyPlus with the resistance-flow characteristics and particulate filtration performance in different operating modes.Simulates the ventilation rate and air filtration efficiency of the ventilator and validates with the experimental data.Simulates the indoor air quality and operating energy consumption in a typical apartment utilizing the ventilators in different climatic zones.The results show that meeting the required indoor air quality,the ventilator shortens approximately 70%of the running time at the HEPA filtration mode,compared with the outdoor air blower with the HEPA filtration,and the annual operating energy consumption per unit area is also approximately 30%lower.
