摘要
楼宇冷热电联供系统能够将冷、热、电三种负荷有机地结合到一起,充分利用低品位的热能实现能源的梯级利用,具有较高的能源利用效率.综合考虑经济、环保、节能、可靠性等指标,对楼宇冷热电联供系统进行方案选择.根据灰色系统关联分析法和层次分析法原理,建立了楼宇冷热电联供方案评价分析数学模型,以某图书馆为例进行了冷热电联供方案分析,找到了综合最优方案.通过客观地选择评价指标和权重系数,提高了冷热电联供方案选择的全面性和科学性.
Building Cooling, Heating and Power（BCHP） system that combine cooling, heating and power load in one unit to realized cascade utilization of energy by using low grade heat, it can use energy resources more efficiently. In this paper, according to theories of Grey Relation Analysis （GRA） and Analytical Hierarchy Process （AHP）, mathematical model of synthesizes evaluation is established and used to select BCHP system with considering indexes of economy, environment protection, energy saving and reliability as main factors. The optimal project to a library with BCHP is selected according to GRA and AHP theories. Both evaluate indexes and weight coefficients are chosen with objectivity in order to improve comprehensive and scientific performance of selection on BCHP schemes.
