Research, development and testing of fixed-bed heat and moisture regenerators

在加拿大，建筑所消耗的能源中至少有一半用于供暖、通风和空调(HVAC)。为了给建筑物提供足够的通风空气，大量的能源被用来调节室外空气。几个空气对空气交换器被用来回收废气中原本浪费的能量，以便在室外空气供应给建筑物之前对室外空气进行预调节。然而，一组被称为固定床回热器的空气-空气交换器最近被应用于建筑暖通空调系统，它们的应用仅限于热回收。本项目的目的是开发、测试和优化固定床热湿回热器的性能。固定床再生器的工作原理是周期性地颠倒流经热/湿交换器的室外气流和排气气流的方向。这些再生器潜在地保证了热量和水分回收的高效率。

In Canada, at least half of the energy consumed in buildings is used for heating, ventilating and air-conditioning (HVAC). A substantial amount of energy is used to condition outdoor air in order to provide adequate ventilation air to buildings. Several air-to-air exchangers have been used to reclaim the otherwise wasted energy in exhaust air to precondition outdoor air before outdoor air is supplied to buildings. However, a group of air-to-air exchangers called fixed-bed regenerators have recently been applied to building HVAC systems, and their application is limited to only heat recovery. The aim of this project is to develop, test and optimize the performance of fixed-bed heat and moisture regenerators. The fixed-bed regenerators work by periodically reversing the direction of outdoor and exhaust air streams that flow through a heat/moisture exchanger. These regenerators potentially guarantee high efficiency for both heat and moisture recovery.
