摘　　要：以夏热冬冷地区某户式辐射空调系统作为研究对象,针对不同时间段墙体内部传热量大小和方向的不同,提出了夏季白天和夜间设定不同室内温度运行策略,通过调整室内设定温度,使得房间负荷与墙体蓄放热性能相配合,达到辐射空调系统节能和节约运行费用的目的。通过夏季夜间不同设定温度下,辐射末端表面温度、外墙内表面温度、热流密度及系统能耗变化的实验研究,结果表明:相对于夜间室内设定温度为24℃,当温度设定为22℃时,夏季全天耗电量可节约2.21%左右,用电费用节约3.75%左右。研究结果十分有利于平衡社会白天和夜间的用电量,提高电网的输送效率和发电厂的总体发电效率,节约能源,降低碳排放量。By taking a household radiation air conditioning system in hot summer and cold winter area as the research object,this paper proposed the operation strategy of setting different indoor temperature during summer and at night according to the different heat transfer quantity and direction of the wall in different time periods.By adjusting indoor temperature,room load and wall storage and discharge performance can save energy and operation cost.The experimental results show that when the temperature is set at 24℃,when the temperature is set at 22℃,the whole day power consumption can be saved about 2.21%in summer and about 3.75%in electricity consumption.The results of this paper are also very helpful to balance the power consumption of society during the day and at night,to improve the transmission efficiency of the power grid and the overall power generation efficiency of the power plant,to save energy and to reduce carbon emissions.
