摘　　要：文章对安装了地板新风+地板辐射供暖系统的住宅样板房主卧室的空气温度和CO_(2)浓度进行实测,分析了房间的室内热环境及污染物浓度分布特征。结果表明,辐射供暖系统开启后房间温度在190 min左右升至最高,此后逐渐趋于稳定,且温度值略低于设定温度。室内温度呈下高上低分布,坐姿头足温差和站姿头足温差随系统运行逐渐增大,稳定时分别趋于0.3℃和0.6℃。辐射地板温度和室外温度是影响室内温度的主要因素。室内高度方向的CO_(2)浓度分布主要受室内人员位置和新风口位置的影响,辐射供暖房间内地板新风系统的排污效率与ASHRAE 62.1标准规定的推荐值相符。Air temperature and CO_(2) concentration in the bedroom of a residential model room with floor fresh air system and floor radiant heating system are tested.The thermal environment and pollutant concentration distribution characteristics of the room are then analyzed.The experimental results show that the indoor temperature of the bedroom during radiant heating reaches the highest value at about 190 min,and then gradually becomes stable.The steady temperature is slightly lower than the set temperature.Air temperature in high area is higher than that in low area,and the temperature difference between the head and the foot of sitting or standing people tends to be 0.3℃ and 0.6℃ respectively.The indoor temperature is mainly influenced by the floor temperature and outdoor temperature.The vertical distribution of indoor CO_(2) concentration is mainly affected by the positions of indoor people and the fresh air outlet.The discharge efficiency of the floor fresh air system is about 1.1~1.2,which is in line with the recommended value specified in ASHRAE 62.1 standard.
