文献聚类视角下的中国热泵研究进展
Research progress of heat pumps in China from perspective of literature clustering
摘要：
在使用文献计量法分析了超过15 000篇文献引文信息的基础上，通过对1994—2020年中国热泵研究方向进行聚类，从宏观上描述主要领域和总体发展趋势，并详细综述了当前最为活跃的4个领域：地源热泵、空气源热泵-结除霜、空气源热泵-供热和太阳能辅助热泵。地源热泵聚焦于换热器和热不平衡现象的研究；空气源热泵是近年来最热门的研究方向，结除霜的研究经历了从结霜/除霜机理研究、除霜方法、蓄热除霜到无霜运行的转变；复叠蒸气压缩式空气源热泵与制冷剂喷射技术是提高空气源热泵在严寒、寒冷地区适用性的主要方向。指出工业热泵可能是未来热泵研究的发力点；电动车热泵及热泵热水器产业化需求旺盛。
Abstract：
Based on the analysis of more than 15 000 citation information using the bibliometric method, this paper clusters the research directions of heat pumps in China from 1994 to 2020, describes the main areas and overall development trends in a macroscopic view, and reviews the four most active areas at present: ground-source heat pump, air-source heat pump (ASHP)-frosting and defrosting, ASHP-heating and solar-assisted heat pump. Ground-source heat pumps focus on the study of heat exchangers and thermal imbalances. The ASHP is the most popular research direction in recent years. The research on frosting and defrosting has undergone a transition from frosting/defrosting mechanism, defrosting methods and heat storage defrosting to frost-free ASHP. Cascade vapor compression ASHP and refrigerant injection technology are the main efforts to improve the applicability of ASHP in cold and severe cold zones. It also points out that industrial heat pumps may be the focus of future heat pump research, and the industrialization of electric vehicle heat pumps and heat pump water heaters is in strong demand.
