冬季北方地区住宅建筑通风方式对比研究

随着住宅节能技术的广泛推行，对窗户的气密性要求越来越高，冬季冷风渗透远远不能满足室内人员对新风的最低需求。为了寻找节能、舒适的通风方式，本研究利用FLUENT对工程中较为常见的通风方式：自然通风方式、自然进机械排通风方式、带热交换的墙式通风器方式、带热交换的通风换气机组方式在气流组织、舒适性能、能耗特性及初投资方面进行了应用效果评价。最终得出：对于层高和装修标准较高的高级住宅中使用带热交换的通风换气机组，可以使通风系统在满足热舒适性和空气品质的基础上，更加节能，而对于一般住宅建筑，自然进机械排通风方式是相对最优选择。

Comparative Study on the Ventilation Mode of the Residential Building in North Area in Winter

With the development of residential energy conservation technology, the air tightness requirement of the window is higher and higher. So in winter the cold penetration wind cannot satisfy the requirement of indoor personnel to fresh air. The common ventilation mode includes natural ventilation, natural inlet and mechanical exhaust, wall type ventilator with heat exchange, ventilation unit with heat exchange. Looking for energy saving, comfortable way of ventilation, the application effect of the way of ventilation is evaluated in air distribution and comfort performance and the energy consumption features by using FLUENT software. Results show that ventilation unit with heat exchange mode is the best ventilation mode in the senior residential, which can satisfy the ventilation system in thermal comfort, air quality and more energy efficient. For general residential building, the natural inlet and mechanical exhaust ventilation mode is the optimal choice.
