暖通空调(heating,ventilation,and air conditioning,HVAC)系统是目前营造健康、舒适封闭/半封闭空间环境的重要手段,但现有HVAC系统不仅能耗高,而且容易引起人体健康问题,比如病态建筑综合征、建筑相关疾病、传染性疾病交叉感染等.上...暖通空调(heating,ventilation,and air conditioning,HVAC)系统是目前营造健康、舒适封闭/半封闭空间环境的重要手段,但现有HVAC系统不仅能耗高,而且容易引起人体健康问题,比如病态建筑综合征、建筑相关疾病、传染性疾病交叉感染等.上述现象进一步说明由HVAC系统末端形成的室内气流组织(基于传统方法)仍不够完美,存在一定的盲区与不足.为了解决传统HVAC系统末端在设计与使用过程中存在的问题,逆向设计方法应运而生.与传统方法区别最大的是,逆向设计方法可以在每个设计循环确定最优的方向向量,而传统设计方法只能不断试错.为进一步阐明两类方法的差异并促使逆向设计方法不断改进,本文首先阐述了室内环境营造所面临/需要解决的科学问题;其次,对气流组织设计方法的分类及其基本原理进行了详细介绍;然后,通过真实的案例结果展示了两类方法的设计效果.虽然逆向设计方法在室内环境营造领域已取得了较大的进展,但目前的逆向设计方法仍需要理论推演、程序开发和数值求解等过程,在一定程度上阻碍了其推广应用.最后,本文讨论了室内环境营造领域未来可能的发展方向.比如,随着人因工程学、逆向设计方法、数字化设计方法、智能控制等领域的快速发展,室内环境设计与营造将趋向于多样化、智能化、智慧化.展开更多
