Energy recovery ventilator design: connecting material properties to optimal design

能量回收通风机（ERV）在为建筑物带来更多新鲜空气的同时节省能源。采用透汽膜的ERV有很大的发展前景，但相对较新；污垢对其长期性能的影响尚不清楚。ERV组件正在迅速发展（新的膜材料，新的流动几何形状）。dPoint技术公司是ERV生产领域的全球领导者，该公司需要能够将材料（包括膜降解的影响）和流动几何形状与整体核心性能联系起来的基础数据和设计模型。在提出的工作中，将开发一种快速计算工具，以确定给定局部传热和传质系数信息的ERV核心的整体有效性。同时，本研究也为研究膜的特性和流道设计对局部传热传质的影响提供了新的基础测量方法。

Energy recovery ventilators (ERV) save energy while bringing more fresh air into buildings. ERV's using vapor permeable membranes have great promise but are relatively new; the impact of fouling on their long-term performance is unknown. The ERV components are evolving rapidly (new membrane materials, new flow geometries). dPoint Technologies, a global leader in ERV production, requires fundamental data and design models capable of linking materials (including the effect of membrane degradation) and flow geometry to overall core performance. In the proposed work, a fast computational tool will be developed to determine the overall effectiveness of an ERV core given information about local heat and mass transfer coefficients. Also, this work will provide fundamental new measurements are needed of membrane properties and the influence of flow passage design on local heat and mass transfer.
