Abstract

This paper analyzes the regenerative elevator operation and energy savings of the faculty elevator. The study is based on measurements taken during a week of high travel demand. The results are compared to previous weekly measurements taken with the same elevator during lower travel demand. The effects of travel demand on regenerative potential and energy efficiency are analyzed. Energy savings are calculated using two different approaches and the impact of standby energy is highlighted. In addition, the energy efficiency, total annual energy consumption and annual energy savings are calculated according to the energy efficiency classification standards VDI 4707 and ISO 25745 and compared with the results of measurements performed at low and high travel demand. The regenerative cycles are studied in detail to determine the requirements for a future energy storage system. The results have shown that increased travel demand increases the energy efficiency of the elevator system. This effect is not obvious when considering only the results obtained according to the elevator energy efficiency classification standards. Moreover, the overall energy efficiency of the elevator system can be further improved by reducing the energy consumption in standby mode.

蓄热式电梯蓄热循环与能效分析

对学院电梯的再生运行及节能进行了分析。这项研究是基于一周高出行需求期间的测量结果。结果与之前在较低出行需求期间使用同一部电梯进行的每周测量结果进行了比较。分析了出行需求对再生潜力和能源效率的影响。使用两种不同的方法计算节能，并强调待机能源的影响。此外，根据能源效率分类标准VDI 4707和ISO 25745计算了能源效率、年度总能耗和年度节能，并与低和高旅行需求下的测量结果进行了比较。详细研究了再生循环，以确定未来储能系统的要求。结果表明，出行需求的增加提高了电梯系统的能源效率。如果只考虑按照电梯能效分类标准得出的结果，这种影响并不明显。此外，通过降低待机状态下的能耗，可以进一步提高电梯系统的整体能效。
