摘要
针对某些工程中未考虑自然通风对通风设备选择的影响而造成初投资偏大、运行费用偏高的问题,通过建立建筑分析模型引入了一种计算风压的方法。从理论上推导出热压、风压以及二者共同作用下的自然通风计算方法。结合具体工程,通过分析计算得出了考虑自然通风对通风设备选择的影响可以减小通风设备容量,从而节约能源。
Aiming at the existed problems of higher investment and running costs in some projects resulting from not considering the influence of natural ventilation on selection of ventilation equipments, introduces a new method of wind pressure calculation by developing an analytic building model. Deduces theoretically the natural ventilation calculation under the action of thermal pressure and wind pressure individually and simultaneously. With an actual project, concludes that the ventilation equipment can be smaller in capability when considering the effect of natural ventilation, consequently energy consumed being less.
