建筑自然通风是一种自然而又必然的趋势是指利用自然的手段(风压、热压)来促使空气的流动,将室外的清新空气引入室内不断地更替,从而维持室内空气的舒适性满足人体健康的生理需求。建筑通风目前主要有三种方式:自然通风、机械通风、机械辅助自然通风。自然通风是指充分利用自然环境条件,节能、环保,并且更容易被人的生理感知接受,但是单一的自然通风有一定的缺陷,气流不够稳定,组织和控制有一定的难度,机械通风能够提供较稳定的 Natural ventilation is a natural and necessary trend refers to the use of natural means (air pressure, hot pressing) to promote the flow of air, the outdoor fresh air into the room continue to replace, so as to maintain the comfort of indoor air to meet Physiological needs of human health. There are currently three main types of building ventilation: natural ventilation, mechanical ventilation and mechanical ventilation. Natural ventilation refers to making full use of natural environmental conditions, saving energy, protecting the environment, and being more easily accepted by human physiology. However, a single natural ventilation has certain defects, the airflow is not stable enough, the organization and control have some difficulties, and mechanical ventilation can provide More stable
