本文采用计算流体力学（CFD）方法，对一个6 m × 4 m × 3 m的模型房间，在采用辐射板供暖和供冷的情况下的热舒适特性进行了研究。综合考虑了ISO 7730和ASHRAE 55标准中描述的一般热舒适参数PMV（平均投票百分比）、PPD（预测不满意百分比）和局部热舒适参数（辐射温度不对称性、通风、垂直空气温差、冷暖地板）。辐射板已被放置在外墙上用于加热系统，并且它们已被放置在外墙和天花板上用于冷却系统。根据TS 2164标准，确定了土耳其供暖和制冷季节室外气候条件的不同区域，并对每个区域进行了供暖/制冷分析。从辐射板的热通量和相应的房间平均温度值所需的，以满足由标准ISO 7730所描述的热舒适的条件已确定为这些地区和加热/冷却系统配置。针对这些地区和供热/供冷模式，对辐射系统的节能潜力进行了评估。
In this study characteristics of a model room with dimensions 6 m × 4 m × 3 m has been investigated using Computational Fluid Dynamics method with regard to thermal comfort, in case of that the room is heated and cooled by the means of radiant panels. Both general thermal comfort parameters [PMV (percentage mean vote), PPD (predicted percentage of dissatisfied)] and local thermal comfort parameters (radiant temperature asymmetry, draught, vertical air temperature difference, warm and cool floors) which are described by the standards ISO 7730 and ASHRAE 55 have been taken into consideration. Radiant panels have been placed to exterior walls for heating system, and they have been put on both exte\rior walls and ceiling for cooling system. According to the TS 2164 standards, different regions are identified with regard to outdoor climate conditions for heating and cooling seasons in Turkey, and analysis of heating/cooling is done for each region. Heat fluxes from radiant panels and corresponding values of room mean temperature required in order for the conditions of thermal comfort described by the standards ISO 7730 to be met have been determined for these regions and heating/cooling system configurations. Energy saving potential of radiant system has been evaluated for these regions and heating/cooling mode.
