基于Airpak的夏季夜间通风风速对室内热环境和热舒适性影响模拟研究

运用数值模拟分析方法,研究了夏季夜间通风风速对房间热环境的影响。首先利用模拟软件Airpak建立了一间房间分析模型,随后模拟、分析不同风速对室内热环境及舒适度的影响。结果表明:夏季夜间通风对室内热环境及舒适度都有较好的改善作用,并且有利于空调节能;风速越大室内的热环境越满足人体的舒适度需求。

This paper discussed the effects of night ventilation and wind speed on the thermal environment of the room by numerical simulation.First,an room analysis model based on actual situation was established with the simulation software Airpak,and then the effects of the indoor thermal environment and comfort performance in different wind speeds were simulated.The results show that night ventilation in summer can improve indoor thermal environment and comfort performance,and it is beneficial to energy saving of air conditioning.The greater the wind speed,the greater the indoor thermal environment to meet the human body's comfort requirements.
