辐射采暖住宅建筑能耗与室内作用温度

Energy Consumption and Operating Temperature of Residential Building by Using Radiant Heating

对南京地区冬季采用地板辐射采暖的住宅进行了房间空气温度、围护结构表面温度、热源设备能耗的实测 ,在此基础上计算了室内平均辐射温度 (MRT)和作用温度 (OperationTemperature) ,并对外墙比例不同的房间的作用温度进行了对比 .研究结果证明 ,由于现有 2 40砖墙的住宅建筑围护结构保温性能较差 ,两面外墙较之一面外墙的房间 ,作用温度可相差 1℃以上 .对于所介绍的采暖系统形式 ,采暖期 (以 90d计 )每m2 建筑面积电耗 ,根据运行模式和室内设计温度的不同 ,为7.3kWh至 5 2kWh .

The air temperature, inner surface temperature and heating equipment energy consumption in winter season were measured for an apartment equipped with radiant heating system. Based on the measured results, the average radiant temperature and operating temperature of different rooms with different outside walls were calculated and compared. The results show that the operating temperature of rooms with two sides of outside walls is more than 1℃ higher than that with one side of outside wall. The range of the energy consumptions of the heating system varies from 7.3?kWh/m 2 to 52?kWh/m 2 for a heating season, depending on the equipment operating models and room design temperatures.
