摘要
为了确定空气源热泵无水地板采暖系统在华北地区的适用性,以一栋高层住宅楼为例,利用建筑能耗分析软件Dest对其进行逐时能耗模拟。通过经济性分析,并与燃煤锅炉集中供热采暖方式进行比较,得出无水地板采暖系统能源利用效率较高,其经济性随着煤价的提高而增加,采用峰谷电价可以更好地体现其经济性;并且确定了无水地板采暖系统在华北地区的节能经济区域。
In order to confirm the applicability of the air-source heat pump radiant floor heating system in north China, using building energy consumption analysis software Dest, the energy consumption simulation is hourly carry out on a high-rise residential building. Through economic feasibility analysis, comparing with the centralized heat- ing coal-fired boiler, it is concluded that energy efficiency of direct floor heating system is higher and its efficiency increases with the increase of coal prices, the peak valley price can better reflect its economy. The economic area of the direct radiant floor system in north China is confirmed.
