夏热冬冷地区住宅建筑新风系统全年运行工况分析

Analyses of Annual Running Conditions for Ventilation System in Residences in Hot Summer and Cold Winter Regions

根据夏热冬冷地区的空调期、除湿期和采暖期的划分方法 ,提出了住宅建筑新风系统全年运行的转换条件 ,以及新风热湿处理工况要求。并针对该地区气候潮湿、除湿期时间长的特点 ,认为节能住宅采用温湿度同时监控的独立新风系统 。

Based on the definitions of air conditioning period, dehumidifying period and heating period, this paper puts forward the exchanging conditions and psychrometric process of ventilation system in residences. Because of the remarkable humid climate in hot summer and cold winter regions, the ventilation dehumidification becomes a more important part of the air treatment system. In order to improve the indoor thermal environment quality, new strategies must be founded to control both temperature and humidity of ventilation system.
