某办公建筑热舒适及能耗的正交法优化

Optimization of Thermal Comfort and Energy Consumption in an Office Building in Orthogonal Method

以重庆某采用地板送风加辐射供冷空调系统办公房间为研究对象,考虑送风速度、送风温度、辐射顶板温度、辐射顶板安装高度等影响因素,以房间热舒适度和能量利用系数的综合评分为优化目标,运用正交法建立4因素3水平正交方案,通过数值计算和极差、方差分析得到各因素对综合评分影响次序,从而得到最优方案,并为此类型空调系统设计提供了参考.

The paper is centering on hybrid air conditioning system with UFAD and radiant cooling panel of an office in Chongqing.Taking into consideration the relevant factors such as airflow velocity,airflow temperature,radiant cooling panel temperature,radiant cooling panel height.To optimize the integrated score from thermal comfort of the room and energy utilizing coefficient,orthogonal tests which include 3 factors and 4 levels have been established.On the basis of CFD numerical calculation,the range analysis and variance analysis,the affecting order has been analyzed.Then,an optimal plan is made,and references for the design of such air-conditioning system are provided.
