Annex 58 High-Temperature Heat Pumps Task 1 – Technologies, Task Report
High-temperature heat pumps are advanced thermal systems that provide heat at temperatures exceeding 100 °C, aking them suitable for a wide range of applications in industry. These heat pumps operate on the same principles as conventional heat pumps but employ modified components and potentially new working fluids that enable them to achieve high efficiency and performance at elevated temperatures. This chapter will provide an overview of high-temperature heat pumps, including a glossary of key terms and important definitions. Working principles, important technologies, working fluids, components, and promising applications are presented to understand their haracteristics and advantages. Further, it will be outlined how these systems can help to reduce energy consumption, lower greenhouse gas emissions, and enhance the sustainability of various sectors.
