为研究毛细管-金属板吊顶的采暖特性和节能潜力,构建了毛细管-金属板辐射吊顶采暖系统,实验分析了系统的实际采暖性能和热舒适性,从地源热泵的COP和末端设备的效率探讨了系统的节能潜力.结果表明,该采暖系统具有良好的热稳定性和热舒适性.当系统达到稳定状态时,辐射传热占总传热量的62.7%,并且总传热量可以满足大多数建筑的采暖需求.与地板辐射供暖系统相比,毛细管-金属板辐射吊顶采暖系统具有预热时间短、供水温度低和采暖能力强的优势.当供水温度为28~33℃时,地源热泵的COP显著提高.当基准温度为5℃时,毛细管金属板辐射吊顶的效率是辐射地板的1.6倍.该新型辐射采暖系统显示出较大的节能潜力.
In order to study the heating characteristics and energy-saving potential of capillary-sheet metal ceiling, a capillary-metal panel ceiling heating system was constructed, and the actual heating performance and thermal comfort of the system were experimentally analyzed. From the COP of the ground-source heat pump and the efficiency of the end equipment The results show that the heating system has good thermal stability and thermal comfort.When the system reaches a steady state, the radiation heat transfer accounted for 62.7% of the total heat transfer, and the total heat transfer can meet most of the building Of the heating demand.Compared with the floor radiant heating system, capillary - metal plate radiation ceiling heating system has the advantages of short warm-up time, low water temperature and strong heating capacity.When the water supply temperature is 28 ~ 33 ℃, the ground source heat pump COP significantly increased.When the baseline temperature is 5 ℃, the capillary ceiling metal radiation ceiling efficiency 1.6 times that of the radiant floor.The new radiant heating system shows a greater energy saving potential.
