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。 Aiming at the condition that the temperature of the upper part of the large space buildings is high in winter and the temperature in the lower part is low, a method of sending outdoor air in the upper part of the room, mixing in a high temperature zone, controlling the amount of air supply with a slight positive pressure to reduce the entry of cold air and increasing the temperature of the lower working zone . Practice shows that this method can not only achieve better heating effect, but also save a lot of heat energy.
