摘要
被动房依靠新风系统实现热回收及调节室内空气质量,合理的新风管道设计尤为重要。本文主要研究了被动房新风系统管道的保温方案及新风管道的新风送风口与回风口位置。通过公式计算对管道保温提出合理方案,并通过管道长度对沿程阻力的影响,利用Airpak软件对被动房办公室新风进行数值模拟所得到室内气流组织的温度场及速度场对新风管道及出口进行设计,望对被动房室内新风设计提供一定的借鉴作用。
Passive Housing rely on fresh air system to achieve heat recovery and adjust indoor air quality.Reasonable design of fresh air pipeline is particularly important.The thermal insulation scheme of fresh air system pipes in passive buildings and the positions of fresh air pipes,fresh air supply outlets and return air outlets are mainly studied.Through formula calculation,a reasonable scheme for pipeline insulation is put forward,and through the influence of pipeline length on resistance along the way,the temperature field and velocity field of indoor air distribution are designed by using Airpak software to simulate fresh air in passive office.This paper could provide some reference for the design of indoor fresh air in passive housing.
