采用数值模拟方法,对一栋住宅分别位于北京、上海和广州时,不同通风量和不同通风模式下的夏季空调能耗进行了计算分析。结果表明,位于北京时,1.0h-1是最节能的通风换气次数,位于上海时,0.4h-1是最节能的通风换气次数,位于广州时,空调能耗随着换气次数的增加而线性增大,在这三个地区,间歇机械通风都有利于减少空调能耗。
Using the numerical simulation method, the energy consumption of summer air conditioners under different ventilation rates and different ventilation modes were calculated and analyzed when a residence was located in Beijing, Shanghai and Guangzhou respectively. The results show that when located in Beijing, 1.0h-1 is the most energy-efficient ventilation, when in Shanghai, 0.4h-1 is the most energy-efficient ventilation, when in Guangzhou, the air-conditioning energy consumption with the number of ventilation Increasing linearly, in all three regions, intermittent mechanical ventilation are conducive to reducing air conditioning energy consumption.
