基于Airpak的空调送风方式对室内热环境影响分析

Study on Influence of Air Supply Mode of Air-Conditioner on Indoor Thermal Environment based on Airpak

空调房间内气流组织的好坏决定着室内空气的质量,因此营造合理气流组织是空调设计的重要组成部分。改善室内空气品质(IAQ,Indoor Air Quality)依赖于有效的通风换气和合理的气流组织。本文利用Airpak对某办公室三种空调送风方式的温度场、PMV-PPD(Predicted Mean Vote-Predicted Percent Dissatisfied)值进行模拟分析,研究结果说明位于中间顶部顶送侧回的空调系统的气流组织效果最佳,从而为改善空调房间的热环境设计提供了方法和理论依据。

In air conditioning room,the form of airflow organization decides the indoor air quality,so the construction of reasonable air distribution is an important part of the air conditioning design.Improving indoor air quality depends on effective ventilation and reasonable air distribution.Through the simulation analysis of the air conditioning temperature field,PMV-PPD(Predicted Mean Vote-Predicted Percent Dissatisfied)values on different placement and air supply mode by Airpak in the office,the results show the effect of the up-inlet and side-outlet air conditioning system is the best,thus it can provides methods and theories to the design of improve thermal environment in air conditioned room.
