条缝型送风空调室内热舒适性分析

Analysis of Indoor Thermal Comfort of Slit Air Supply Air Conditioner

基于Airpak模拟软件,对一采用条缝型风口送风的办公室进行数值模拟,主要包括室内温度、湿度、工作区风速、空气龄、PMV-PPD等,选取室内人员主要活动区域及截面进行室内空气品质及热舒适性分析,得出在垂直高度方向存在明显温度梯度,工作区风速<0.3 m/s,-0.25≤PMV≤0.25,3.75%≤PPD≤7.5%,人体舒适度好,空气品质较好。为优化空调送风形式,改善室内热舒适性提供了新的思路。

Based on Airpak simulation software,numerical simulation is performed on an office that uses slit-type air supply,mainly including indoor temperature,humidity,wind speed in the work area,air age,PMV-PPD etc.The main activity areas and sections of indoor personnel were selected for indoor air quality and thermal comfort analysis.The results show that there are obvious temperature gradients in the vertical height direction,the wind speed in the working area is less than 0.3 m/s,-0.25≤PMV≤0.25,3.75%≤PPD≤7.5%,the human comfort is good,and the air quality is good.lt provides a new idea for optimizing the air supply mode and improving the indoor thermal comfort.
