深埋地下维护结构空调房间气流组织CFD模拟研究

CFD Simulation of the Air Diffusion of Air-condition Room in Deep Underground Enclosure Structure

以南京某深埋维护结构空调房间的夏季工况为例,对现有送回风方式的气流组织进行研究,并提出几种改进方案。研究表明,应适当减小送风速度和提高送风温度。但两种改进方案都存在左右分层的现象,在同样的设计温度下,方案二可以提高送风温度,进而可以减少空调冷负荷,降低能耗。

In this paper, summer conditions in a deep underground enclosure structure air-conditioned room in Nanjing was taken as an example to study the existing air distribution of the air flow, and two improvements were proposed. It showed that the two improved schemes that reducing speed and raise temperature of the air supply both existed the phenomenon of stratification. In the same designed temperature, the second program can raise the supply air temperature, and then, reduce air conditioning＇s cooling load and energy consumption.
