基于VR技术的建筑设计可视化应用研究

针对传统的建筑室内方案展示存在的问题,提出构建一个直观、高效的效果展示的必要性。首先对VR技术的特性分析,提出VR技术在室内方案设计应用的优势。其次,对室内方案制作的几个关键软件、制作流程进行分析,为室内方案展示设计制作做基础。最后以某居室为例,从三维建模、可视化设计、交互设计、三维虚拟漫游进行综合设计与制作,最终实现VR技术下的效果展示。调查研究表明,采用VR技术进行室内方案展示效果更形象、更直观,受到年轻人的青睐。

Design of Control Scheme for Variable Air Volume Air- conditioning System

The air quantity of variable air volume system for the rooms and the total air quantity of the system changes with the change of room load. Combined with the system composition in the laboratory, the paper determines the control scheme of the variable air volume system, that is, indoor temperature-control, indoor positive pressure control, air distribution static pressure control, air-supply temperature control and new air volume control. The dotted lines with arrows mean the output signals from the control unit to actuator, and the solid lines with arrows represent the input signals from the actuator to the control unit.
