关于民用建筑通风室内外计算参数的思考

Considerations in indoor and outdoor air design conditions for ventilation in civil buildings

分析了我国民用建筑通风现状,认为现有的通风室内外设计计算参数不尽合理。建议重新确定通风室内外设计计算参数,根据室内热舒适要求确定通风室内设计计算温度。从划分建筑环境工程节能季节入手,确定城市通风季节,进而确定通风时段,根据通风季节通风时段内的室外空气干球温度的最大值确定通风室外设计计算温度。

Analyses the ventilation status of civil buildings in China.Thinks that the existing indoor and outdoor air design conditions for ventilation are not reasonable to some extent.Proposes to reconsider the determination of the conditions and to determine indoor design temperature for ventilation based on thermal comfort.Beginning with dividing energy saving seasons of building environment,divides the ventilation seasons of cities,and consequently determines the ventilation period.Outdoor air design conditions for ventilation should be determined according to the maximum value of outdoor air dry-bulb temperature within the period of the ventilation season.
