根据节能季节划分方法确定了南京等典型夏热冬冷城市的空调、供暖季节起止日期;计算、比较了重庆、南京、武汉三地空调和供暖季节排风热回收装置可回收的全热量,发现全热交换式换气机应用于南京和武汉的居住建筑中全年运行的节能效益要比应用于重庆显著得多。另外,计算了在南京地区居住建筑中使用全热交换式换气机节能全年所需要的最少运行时间,提出了该地区的居住建筑应用全热交换式换气机的节能运行模式。
According to the method of energy-saving season division, the air-conditioning and heating season start-stop dates for typical hot summer and cold winter cities such as Nanjing were determined. The total heat recoverable by air-conditioning and heating season exhaust heat recovery units in Chongqing, Nanjing and Wuhan was calculated and compared. Total heat exchange ventilator used in residential buildings in Nanjing and Wuhan year-round operation of the energy-saving benefits than applied to Chongqing was significantly more. In addition, the minimum operating time required to save energy in a total heat exchange ventilator in residential buildings in Nanjing is calculated, and the energy saving operation mode of the total heat exchange ventilator in residential buildings in the area is proposed.
