n.下向通風(向下氣流；倒灌風)

Make sure the downdraught cooler be in normal situation during the whole experimental process. 另外要防止皮膚的灼傷。

The stack ventilation strategy was evolved by the introduction of passive downdraught cooling. 引進了被動式向下通風供冷技術(shù)后，豎向風道通風技術(shù)得到了發(fā)展。

However, as the plane approached the intense rain area, winds abruptly backed to northerlies coupled with a rapid increase in downdraught to over 30 knots. 但是當航機接近大雨區(qū)時，風向突然轉(zhuǎn)為北風，并出現(xiàn)急劇加速的下沉氣流，時速超過 30海里。

Passive and Hybrid Downdraught Cooling, which rely on natural cooling processes based on water evaporation and solar power, are now technically viable in many parts of the world. 依靠水蒸發(fā)和太陽能的被動及混合倒風制冷技術(shù)目前在世界上大部分地方得到了廣泛應(yīng)用。

The resulting building is believed to be the first large-scale application of the passive downdraught cooling technique;construction began in late 2003. 該建筑于2003年后期開始施工，相信它將成為第一座大規(guī)模應(yīng)用被動式向下通風供冷技術(shù)的建筑物。
