基于能源、环境、经济评价标准,结合层次分析法,在以电定热运行策略下,以原动机额定容量及蓄热设备额定容量为优化变量,考虑气候条件、建筑类型等影响因素,对中国5个气候区(温和地区、夏热冬暖地区、夏热冬冷地区、寒冷地区、严寒地区)的5个代表城市(昆明、广州、长沙、北京、哈尔滨)的3类公共建筑(宾馆、办公、学校教学楼)的冷热电三联产系统进行优化及评估。结果表明:气候条件、建筑类型对楼宇级冷热电三联产系统均有显著影响,在以电定热运行模式下,楼宇级冷热电三联产的系统性能在热需求大的气候区较优于冷需求大的气候区:哈尔滨〉北京〉昆明〉长沙〉广州;系统性能在同一气候区的不同建筑类型排序为:宾馆〉学校教学楼〉办公楼。
The combined cooling, heating and power system in five representative cities(Kunming, Guangzhou, Changsha, Beijing, Harbin) of the five climate zones of three types of public buildings(hotel, office building, teaching building in school) in China were optimized and evaluated. The system followed electricity demand. Climate condition and building type were taken into consideration. The method was based on energy, environment and economy criteria and combined with analytic hierarchy process. The rated capacity of power generation unit and thermal storage tank were adopted as optimal variables. The results show that the climate condition and building type have a significant impact on system performance; the performance of combined cooling, heating and power system in climate zone where more heating demand is needed is better than in climate zone where more cooling demand is needed: Harbin Kunming Beijing Guangzhou Changsha; system performance of combined cooling, heating and power system for different building type in the same climate zone is: hotel school office.
