固体蓄热式电锅炉在青岛某办公建筑空调系统中的应用

Application of solid thermal-storage type electric boiler in the air conditioning system for an office building in Qingdao

介绍了固体蓄热式电锅炉,结合山东(青岛)国际航运中心项目,对固体蓄热式电锅炉和高效燃气真空热水锅炉2种空调系统的热源方案从经济性和节能性方面作了对比分析。结果表明,固体蓄热式电锅炉的运行费用远低于高效燃气真空热水锅炉,在整个寿命周期内,固体蓄热式电锅炉节省了大量运行费用,经济性优势明显。同时,由于固体蓄热式电锅炉使用低谷电能,对电网有削峰填谷的作用,提高了电网运行效率和稳定性,能有效降低电网的损耗,达到节能减排的目的。

Presents the solid thermal-storage type electric boiler, and combined with the Shandong （Qingdao） International Shipping Center Project, analyses the economy and energy efficiency for the air conditioning system compared with the efficient gas vacuum hot water boiler. The results show that the solid thermal-storage type electric boiler features low annual operating cost and significant economic benefit in the whole life cycle. Furthermore, as the solid thermal-storage type electric boiler uses the off-peak electricity, it improves the efficiency and stability of local power grid while reduces the loss of the grid, and achieves the goal of energy-saving and emission-reduction.
