Energy Recovery: Connecting Core Performance to Building Systems

UBC研究人员与CORE合作开发了通过膜，ERV流道和完整ERV核心的运输过程的预测模型。这些模型包括膜挠曲、可变渗透性和冷凝的影响。然而，这些模型的核心还没有被整合到一个系统模型的通风系统，更不用说一个完整的建筑模型。我们在过去7年的合作中提出了一些重要的系统级问题，我们建议在下一阶段的工作中解决这些问题。 CORE可以设计定制的膜材料。 气候和建筑运行如何影响膜的选择？缓解ERV中冷凝和结霜影响的最佳方法是什么？最近，我们研究了流动引起的膜偏转对ERV性能的影响。 在系统层面，不平衡的流量和建筑压力偏差如何影响系统性能？以前，我们研究了膜污染的影响。考虑到整个建筑的运行，包括渗透率和再循环率，应如何使用过滤器来提高空气质量、ERV寿命和能源效率？ 这些问题与极端污染事件（如野火）和室内空气传播疾病（如疟疾）有关。该计划将资助2名博士生在ERV和建筑规模上开发和验证模型。

UBC researchers working with CORE have developed predictive models of transport processes through membranes, in ERV flow passages, and of full ERV cores. These models include the effects of membrane deflection, variable permeability and condensation. However, these models of the core have not yet been integrated into a systems model of the ventilation system, let alone a whole building model. Some important systems-level questions arise from our collaborations in the last 7 years, which we propose to address in the next phase of work. CORE can engineer custom membrane materials. How do climate and building operation affect the choice of the membrane?What is the best way to mitigate the effects of condensation and frosting in ERVs?Recently we have investigated the effect of flow-induced membrane deflections on ERV performance. At the systems level, how do unbalanced flows and building pressure biases affect system performance?Previously, we investigated the effect of fouling of membranes. Considering whole-building operation, including infiltration and recirculation ratios, how should filters be used to improve air quality, ERV life, and energy efficiency? These issues are relevant to both extreme pollution events (such as wildfires) and indoor airborne transmission of disease (eg. COVID-19).The program would fund a 2 PhD students developing and validating models at the ERV and building scales.
