基于用户需求的分布式供能系统方案设计与分析

摘要

Considering the yearly change of cooling,heating and power loads and the influence of energy storage equipment and lithium-bromide absorption-type chillers with different heat sources in a hospital,designs four distributed energy system (DES) schemes,and analyses the thermal economic indexes of different schemes.Indicates that the basic load,afterburning flue gas,energy storage equipment and evaluating indicators should be considered in designing DES based on requirement of the users.%针对某医院全年冷热电负荷的变化,考虑蓄能装置及不同热源的溴化锂吸收式制冷机的影响,设计了4种分布式供能系统方案,并对各种方案进行了热经济性指标分析.提出基于用户需求设计分布式供能系统时需要考虑基本负荷、烟气补燃、蓄能设备、评价指标.
