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

在加拿大，建筑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，大量的能源被用于调节室外空气。一些空气-空气交换器被用来回收排风中原本浪费的能量，在室外空气进入建筑物之前对室外空气进行预处理。然而，一组被称为固定床蓄热器的空气对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。该项目的目的是开发、测试和优化固定床热湿再生器的性能。固定床蓄热器的工作原理是周期性地改变室外和排气气流的方向，这些气流流经热/湿交换器。这些蓄热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.
