对目前热回收装置进行了回顾，试图确定阻碍热回收技术集成到被动通风系统中的主要因素。近年来，空间供暖和制冷需求的增加，加上英国减少温室气体排放的法定要求，要求技术尽可能高效，消耗最低的能源。热回收技术可以通过预热或预冷降低加热和冷却所需的能量需求来满足这一需求。六种不同的热回收装置进行了分析和比较，适合集成到被动通风系统。热管和旋转热轮被认为是最有潜力的集成技术，因为与其他技术相比，热回收装置的热效率高，压力损失低。高效率是必要的，以回收最大量的热能。要求热交换器两端的压力损失较低，以保持足够的通风率。将热回收技术集成到被动通风中有可能减少建筑物的能源需求，但需要进一步研究以优化回收设备，以实现简单安装，高效率和低压力损失。
A review of current heat recovery devices was undertaken in an attempt to determine the major factors preventing the integration of heat recovery technology into passive ventilation systems. The increase in space heating and cooling demand in recent years combined with statutory requirements to reduce greenhouse gas emissions in the UK requires technology to be as efficient as possible, consuming the lowest amount of energy necessary. Heat recovery technology can meet this demand by lowering the energy demand necessary for heating and cooling by pre-heating or pre-cooling. Six different heat recovery devices were analysed and compared for suitability for integration into passive ventilation systems. Heat pipes and rotary thermal wheels are suggested as the technologies with the most potential for integration due to high thermal efficiency and low pressure loss across the heat recovery device in comparison to the other technologies. High efficiency is necessary to recover the maximum amount of thermal energy available. Low pressure loss across the heat exchanger is required to maintain adequate ventilation rates. The integration of heat recovery technology into passive ventilation has the potential to reduce energy demand in buildings but further research is required to optimise the recovery devices for simple installation, high efficiency and low pressure loss.
