摘　　要：新风负荷在夏热冬暖地区空调负荷中占比可观,采用热回收的方式对新风进行处理能实现良好的节能效益。本文以广州为例,建立数学模型,研究了显热/全热回收装置的全年热回收量,耦合热回收装置增加的风机能耗得出了采用热回收时的全年节约电量。此外,研究了空调EER提高对被动式热回收装置节能性能的影响以及热回收装置结尘对节能效果的衰减作用。Fresh air load accounts for a considerable proportion of the air conditioning load in hot summer and warm winter areas,and the use of heat recovery to treat fresh air can achieve good energy-saving benefits.Taking Guangzhou as an example,this paper establishes a mathematical model to study the annual heat recovery amount of sensible heat/full heat recovery device,and the coupled heat recovery device increases fan energy consumption to derive the annual power saving when heat recovery is used.In addition,the effect of increased air-conditioning EER on the energy-saving performance of the passive heat recovery device and the attenuation of the energy-saving effect by dust formation in the heat recovery device are investigated.
