摘要(Abstract):

对辐射供冷系统空调末端与室内热湿环境之间的能量交换过程进行分析,分析了辐射供冷空调室内热环境参数特点。基于热舒适理论,分析了辐射供冷环境低平均辐射温度对人体热感觉的影响,根据辐射供冷空调的特点,从实际应用的角度出发,分析选择适合辐射供冷空调的室内热环境控制变量。通过分析提出辐射供冷室内热环境控制变量应综合考虑平均辐射温度和空气温度两个指标,可将操作温度作为室内热环境控制的反馈变量。
The energy exchange between air-conditioning terminal devices of radiant cooling system and indoor thermal and humid environment was presented,and the characteristics of indoor thermal environment parameters in radiant cooling environment were analyzed.Based on the thermal comfort theory,the effect of low mean radiant temperature on thermal sensation of people was analyzed.From the perspective of practical application,the appropriate thermal environment control variables for radiant cooled room were analyzed and selected.By analyzing,the paper concluded that indoor thermal environment control variables in radiant cooled room should consider two indicators including mean radiant temperature and indoor air temperature,and the operating temperature can be used as a feedback variable for indoor thermal environment control.
