摘要
辐射供冷系统中辐射板的布置位置对人体舒适性有较大的影响。本文以辐射板-置换通风空调房间为例,采用计算流体力学(CFD)软件,运用两方程湍流模型进行模拟,比较6种组合方式下的室内热湿环境。研究结果表明,辐射板布置在顶板或者墙面与置换通风组合的供冷方式均能满足人体舒适度要求,地板辐射供冷与置换通风结合供冷方式舒适性较差,单独顶面辐射+置换通风这一组合方式是6种组合方式中最舒适的方式。
Radiant panel layout position have a greater impact on human comfort radiant cooling system. In this pa-per, Examples to the use of radiant panel and displacement ventilation systems, air - conditioned room, using computational fluid dynamics （ CFD） software, and two-equation turbulence model to simulate, Comparison of six kinds of combinations of indoor thermal environment. The results show, Radiant panels arranged in a roof or wall displacement ventilation and cooling mode combinations can meet the requirements for human comfort. Radiant floor cooling combined with displacement ventilation is poor comfort cooling mode. Roof radiation and displacement venti-lation system in this combination are six combinations of the most comfortable way.
