摘要
本文以某典型的层式通风供暖办公室为研究对象,通过正交设计的极差分析法,得出不同送风参数和壁面温度对该房间舒适性指标PMV,空气龄,吹风感及垂直温差的影响顺序。基于正交设计的综合平衡法,得到该房间优化的送风参数方案:当壁面温度14℃时,送风角度20°、送风温度27℃、送风速度1.8 m/s。经模拟验证,优化后的房间舒适性达到ISO 7730 A级。
In this paper, a room heated by stratum ventilation was taken as the research object. By using the extremum difference analysis of orthogonal test method, the incidence of different air supply parameters and exterior wall temperature on the indoor thermal comfort index(PMV, LMAA, draft and vertical temperature difference) is obtained.Based on the comprehensive equilibrium method of orthogonal design, the optimization scheme of the air supply parameter scheme of the room is obtained(exterior wall temperature is 14 ℃, air supply angle is 20°, air supply temperature is 27 ℃ and air supply speed is 1.8 m/s). The results show that the optimization scheme makes room thermal comfort reaches ISO 7730 A level.
