摘要
根据水上世界的建筑特点和外部轮廓的特点,分析其夏季和冬季的热压通风模型,计算其进风口和出风口的面积和面积比。当F1/F2在0.56情况下,进风口和排风口全部为环形区域的情况下,气流温度梯度变化比较均匀,顶部气流温度保持在38℃左右,而在人的活动区域(1.5m-2.0m)高度上,气流温度保持在31℃左右,考虑到冲浪嬉水的水温一般在28℃,该温度不会令上岸人有寒冷的感觉,有利于保持舒适性。由于该建筑顶部区域半径随高度增加减少,因此,过分增大排风口的面积会带来施工上的困难,由于排风口同样需要保持较大的余压,F1/F2的合理取值范围在0.56～1.0之间。对室内气流组织的模拟分析,给出室内的速度、温度及湿度的分布,并对室内的热舒适度及通风效率进行评价,得到最优的自然通风方案。
According to the aquatic world＇s construction characteristics and the exterior outline＇s characteristics, analyzes the model of thermo-compression ventilates of summer and the winter to calculate its tuyere and the air outlet area and the area ratio. When F1/F2 in 0.56 situation, the tuyere and the exhaust outlet which are inside the circular regions, the stream temperature gradient＇s changing is quite uniformity, the crown stream temperature should maintain at about 38℃, but inside the human beings area （1.5m-2.0m） which the stream temperature should maintain at about 31℃, the water temperature is generally at 28℃, this makes people who come out from the water will not feel cold in order to feel comfortable. Because this building crown region radius along with increases the reduction highly, therefore, if increase the exhaust outlet＇s area will bring more difficulties, because the exhaust outlet needs to maintain the big excess pressure similarly, F1/F2 reasonable value scope should between 0.56-1.0. According to the current indoor air simulation＇s analysis, the indoor speed, the temperature and the humidity distribution, and the evaluation of indoor hot comfor level and drafting efficiency to obtain the best nature ventilation plan.
