候车厅冬季分层空调CFD模拟研究与实验验证

摘要

本文以某高铁站候车厅为研究对象，通过现场测试候车厅物理尺寸及相关空调参数，结合Airpak3．0专业模拟软件对候车厅冬季分层空调气流组织进行模拟，并将模拟结果与实测值进行对比分析，验证CFD模型的可靠性，最后采用PMV—PPD指标对室内舒适性进行评价，旨在为高大空间空调系统设计提供参考依据。%This article based on a high-speed railway station waiting room as an illusion, the waiting room physical size and related air-conditioning parameter get by local testing, combined with Airpak3.0 simulation software to simulate stratified air-conditioning air distribution in winter of the waiting room, and analysis the simulated result and testing result by compare, verify the CFD model is feasible, Finally adopts PMV-PPD index to evaluate the indoor comfortableness, aimed to provide a reference for air-conditioning system design of the large space.
