某高层建筑空调室外机布置改造方案的CFD辅助设计

In this paper, the background focus on a high-rise comprehensive office building in Chongqing that owns a small machine room, and the layout of the air inlet and exhaust is limited. This leads to the problem that the VRV air-conditional system cannot be run normally in summer. Considering the technical requirements for the operation of VRV air-conditional system, the acceptable conditions for investors and the site situation, several outdoor machine layout schemes are proposed. Therefore, this paper uses CFD numerical simulation software to simulate and analyze the inlet and outlet area thermal environment, and propose a suitable renovation program. The numerical simulation software can intuitively predict the outdoor thermal environment of different programs, which contributes to reduce costs, and avoid blind construction.
