Study on the Energy-saving Performance of Heat Recovery Devices in Hot Summer and Warm Winter Areas
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.
