摘要
被动房仅依靠新风换气机实现通风和热回收,能大幅度降低建筑能耗,且办公室作为工作人员长时间停留场所,增强室内通风效果具有重要意义。本文主要研究了地送风出风口与排风口的不同数量及不同位置对被动房办公室气流组织的影响。利用Airpak软件对被动房办公室地送风进行数值模拟,得到室内气流组织的温度场及速度场,并采用PMV-PPD对室内人员热舒适性及空气品质进行了评价。在通风效果方面,对被动房办公室的地送风设计进行了优化。
Passive Housing only rely on fresh air ventilators to achieve ventilation and heat recovery,which can significantly reduce building energy consumption.As office is a place where staff stay for a long time,it is of great significance to enhance the indoor ventilation effect.This paper mainly studies the influence of different number and location of ground air supply outlet and exhaust outlet on air distribution in passive office.Airpak software is used to simulate the air supply in passive offices.The temperature and velocity fields of indoor air distribution are obtained by numerical simulation of ground air supply in passive office with Airpak software,as well as the thermal comfort and air quality of indoor personnel are evaluated by PMVPPD.In terms of ventilation effect,the design of ground air supply in Passive Housing is optimized.
