住宅建筑空调联合电扇调风策略节能潜力分析

Analysis of Energy Saving Potential of the Air Adjustment Strategy of Combining Air Conditioners with Fans in Residential Building

在满足室内热舒适的前提下,空调联合电扇调风策略可提高空调设定温度,降低空调能耗。为评估在住宅中使用电扇调风策略的节能潜力,选取各建筑热工设计分区典型城市的典型住宅并设置对应的通风模式,利用DeST-H软件进行模拟。结果表明电扇调风策略对各区各类住宅均有显著的节能效果,但受气候区类型、通风模式影响较大。通过进一步分析,得到了节能效果的影响规律,提出了实际应用建议。

On the premise of ensuring the indoor thermal comfort,the air adjustment strategy of combining air conditioners with fans can raise the temperature set point of air conditioning and reduce its energy consumption.In order to evaluate the energy-saving potential of using this strategy in residential buildings,typical houses in typical cities of five building thermal engineering design zones were selected with corresponding ventilation modes set up,and simulated using DeST-H software.The results show that the fan air adjustment strategy has a significant energy-saving effect on all kinds of residential buildings in each zone,but is greatly influenced by the type of climatic area and ventilation mode.Through further analysis,the influence law of energy-saving effect was identified,and some suggestions for practical application were proposed.
