排风热回收技术在夏热冬冷地区居住建筑中的应用研究
Application of exhaust air heat recovery technology to residential buildings in hot summer and cold winter zones
摘要：
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。
Abstract：
Based on the division method of energy-saving seasons, determines the beginning and end dates for air conditioning and heating seasons in the typical cities such as Nanjing where it is hot in summer and cold in winter. Calculates and compares the total energy recovered by exhaust air heat recovery units in air conditioning and heating seasons in Chongqing, Wuhan and Nanjing. The results show that much more energy-saving benefit is obtained by applying the total heat exchange ventilators to residential buildings in Nanjing and Wuhan than that in Chongqing all the year round. In addition, calculates the minimum running time of using the devices in the residential buildings in Nanjing. Puts forward the energy-saving operation mode for using the devices in residential buildings in Nanjing.
