夏季通风屋顶风机用于改善冬季供暖效果的设计及运行
Heating effect improvement by roof ventilators in a large workshop
摘要：
针对大空间建筑冬季上部温度偏高、下部温度偏低这一状况，提出了房间上部送室外风、在高温区混合、微正压控制送风量以减少冷风进入并提高下部工作区温度的方法。运行实践表明，该方法不但可以取得较好的供暖效果，还可以节省大量热能。

Abstract：
The temperature is higher in the upper part and lower in the occupied part of a large space in winter. To solve this problem, proposes to supply outdoor air by the roof ventilators, mix it with indoor air in the higher temperature area and depress the cold air quantity by minor positive pressure control, which proves to be a desirable method in reaching a good heating effect and saving energy through practical usage in a power generating plant.
