【摘要】：CO_2跨临界热泵循环,其制冷剂工质为CO_2,不可燃,无毒,无刺激性气味,零臭氧层破坏能力(ODP=0)以及微乎其微的温室效应(GWP=1)而对环境无害,可从工业生产中回收,逐渐成为被广泛应用的热泵技术。本文从国内外CO_2热泵技术的研究现状及应用现状出发,总结概述了目前典型的CO_2热泵循环系统应用案例,如单级压缩供给加用热水系统、双级压缩带中间补气供给家用热水系统、家用供暖及供给热水于一体的双热泵单元家电辅热系统、大型公用建筑用CO_2热泵系统,并从系统层面对影响CO_2热泵循环系统效率的相关热力学参数进行循环分析,如水箱进出水温度、气冷器水流量、系统的制冷剂充注量等参数的控制。以期为未来CO_2热泵技术在中国的发展、进一步研究和应用设计提供一些参考和依据。
[Abstract]:CO_2 transcritical heat pump cycle, the refrigerant CO2, non-flammable, non-toxic, non-irritant odor, zero ozone layer damage capacity of ODP0) and very little Greenhouse Effect GWP1) and environmentally sound, can be recovered from industrial production, It has gradually become a widely used heat pump technology. Based on the research and application status of CO_2 heat pump technology at home and abroad, this paper summarizes the typical application cases of CO_2 heat pump circulatory system, such as single-stage compression supply and hot water system. Two-stage compression with intermediate air supply for domestic hot water system, home heating and hot water supply in one of the dual-heat pump unit home appliances auxiliary heating system, large-scale public buildings used in CO_2 heat pump system, The thermodynamic parameters affecting the efficiency of CO_2 heat pump cycle system are analyzed from the system level, such as the water temperature in and out of the water tank, the water flow rate of the air cooler, the refrigerant charge of the system, and so on. In order to provide some reference and basis for the future development of CO_2 heat pump technology in China, further research and application design.
