摘　　要：介绍了一类新型的热泵型天然气热电冷联供系统,系统利用吸收式制冷机在冬季兼作热泵运行,提高了系统的能源利用效率,降低了运行成本,除了增加一个回收冷凝热的换热器外,不会过多增加系统的额外初投资。通过对该系统的理论和实践研究表明,这类系统能充分利用天然气这种高品质能源,提高系统的综合利用效率。Presents a novel type of heat pump type CCHP system using the absorption chiller as heat pump in winter, thereby energy efficiency of the system can be improved and the operation cost reduced, while the initial cost would not be increased excessively except for a condensation heat exchanger. Through theoretical and practical research concludes that this kind of system can use the high quality natural gas energy adequately and improve the system comprehensive efficiency.
