该文总结了离心式热泵的一些基本技术特点和适用范围。在三联供系统中应用离心式热泵机组,应考虑项目的热源情况、系统需求、运行模式(冷热兼用还是仅供热)等,进行技术经济分析后作出最优化的选择。结合上海某商务区能源中心的设计案例分析后发现,与采用市电和燃气锅炉的常规能源系统相比,全年用电量可减少19.7%,用气量减少41.1%,碳排放量减少达26.5%。 This paper summarizes some of the basic technical features and application of centrifugal heat pump. In the triple system for centrifugal heat pump units, should consider the project’s heat source, system requirements, operating mode (both hot and cold or heat), technical and economic analysis to make the optimal choice. Combined with the design case study of a CBD in Shanghai, it was found that annual electricity consumption was reduced by 19.7%, gas consumption by 41.1% and carbon emission by 26.5% compared with conventional energy systems with utility and gas boilers %.
