Technology Intelligence: Heat Pump Water Heaters

Summary

Heat pump water heaters (HPWHs) have become an important concept in renewable energy and energy efficiency and other disciplines. Science and technology departments around the world are working on ways to reduce the cost of energy and optimize the energy efficiency. In this chapter, a multiple perspective metrics analysis method is studied for characterizing and interpreting the structure and dynamics of bibliometrics and patent analysis in the field of HPWHs from the years 2010 to 2020. Keyword analysis research has been less studied for HPWHs, even though keywords are important for achieving better understanding of the energy efficiency of heat pumps. We aimed to use four resources to discover the most cited papers, top authors, and technologies in the field of HPWHs from Scopus, Web of Science, Sumobrain, and Derwent innovation index. The overall results proved that the USA and China are the most collaborating countries, with the most top authors and the top patents related to the HPWHs technologies.
