【摘要】 以某宾馆建筑为例,对该宾馆楼宇分布式供能系统在我国4种不同气候条件下采用以电定热、以热定电两种运行模式的性能差异进行了节能性、经济性分析。以热定电运行模式比以电定热运行模式节能,但受电、燃气价格的影响,经济性并不是总比以电定热模式优。由于不同地区电、燃气价存在差异,在不同气候条件下应用楼宇分布式供能系统的经济性差别较大。更多还原

【Abstract】 Taking a hotel building for example,the performance difference of building distributed energy supply system operated at the electricity tracking mode and the heat tracking mode under four different climate conditions in China is analyzed from aspects of energy saving and economic efficiency.The energy saving of the heat tracking mode is more than that of the electricity tracking mode,but influenced by electricity and gas prices,its economic efficiency is not always better than that of the electricity tracking mode.Due to the difference in electricity and gas prices among different regions,the difference in economic efficiency of using building distributed energy supply system under different climate conditions is greater.更多还原
