贵州省办公建筑夏季通风降温技术的适宜性分析

Analysis on Suitability of Applying Ventilation Cooling Strategy in Summer of Office Buildings in Guizhou Province

根据典型气象年数据统计得出贵州省夏季室外干球温度和相对湿度的分布规律,以室外干球温度低于31℃,相对湿度低于90%作为通风降温有效性的判定指标。利用Climate Consultant软件分析毕节、贵阳、遵义三个地区办公建筑应用通风降温措施的适宜性。分析结果表明：毕节、贵阳、遵义地区办公建筑采用通风代替空调,分别可以减少47.1%、69.8%、49.7%的空调使用率。贵州省办公建筑应用通风降温技术每年可节省冷量21-31.5k Wh/m2。因此,在贵州省办公建筑的应用通风降温措施是完全适宜的。

The distribution of outdoor dry bulb temperature and relative humidity of Guizhou Province in summer are presented on the basis of the typical meteorological year data statistics. In this report, outdoor dry bulb temperature below 31℃ and relative humidity below 90% are chosen as effective indicators of ventilation cooling. The effectiveness of office building ventilation cooling in Bijie, Guiyang, and Zunyi is analyzed by the software Climate Consultant. The analysis shows that when office buildings adopt ventilation as a cooling method, the rates of using air conditioning in Bijie, Guiyang and Zunyi are reduced by 47.1%, 69.8%, and 49.7%, respectively. In addition, the ventilation strategy applied in office buildings in Guizhou achieves the goal of reducing annual electricity consumption by 21-31.5 k Wh/m2.All the evidence suggests that ventilation cooling strategy is suitable for office buildings in Guizhou Province.
