桂林地区干栏式木构建筑夏季夜间通风降温试验研究OA

Based on the construction of the stilted buildings,a scaled model design comparison test is conducted to evaluate the effectiveness of night ventilation for cooling,the impact of optimizing the ventilation method on the cooling efficiency,and the cooling effect under the coupling of multiple technologies.The results show that in conditions 1 and conditions 2,night ventilation can effectively reduce the indoor temperature and thermal discomfort of the stilted wooden structure buildings.The indoor temperature decreased by 1.82℃,and the number of uncomfortable periods decreased by 21.44.In conditions 3 and conditions 4,the night ventilation cooling effect is improved by optimizing the ventilation path and increasing the opening area.In conditions 5 and conditions 6,the cooling effect of night ventilation is significantly enhanced,with the maximum temperature reduction being 4.35℃.On sunny days,the outdoor temperature is higher,and the outdoor temperature drops below the indoor temperature at night.Night ventilation has a good cooling effect.On cloudy days,the outdoor temperature is lower throughout the day,making it suitable for full-day ventilation.
