随着民用建筑节能设计标准的贯彻与实施,大批节能采暖居住建筑已在各地落成投入使用,这类节能建筑的主要特点是保温与气密性能都比普通的采暖居住建筑有了较大幅度的提高。在一定程度上达到了节约采暖能耗和改善室内热环境的目的,受到居民欢迎。但随之而来的是室内换气时间的加长和空气质量有所下降。如何在气密性能得到改善的情况下,获得良好的室内空气质量,最经济和最有
With the implementation and implementation of energy-saving design standards for civil buildings, a large number of energy-saving and heating residential buildings have been completed and put into use in various places. The main feature of this type of energy-saving buildings is that their insulation and air-tightness properties are larger than ordinary heating residential buildings. improve. To a certain extent, it has achieved the purpose of saving heating energy consumption and improving the indoor thermal environment, and it has been welcomed by residents. But with it, the length of room ventilation and the air quality have decreased. How to obtain good indoor air quality with improved air tightness, the most economical and the most
