dc.titleLarge-scale heat pumps: market potential and barriers, classification and estimation of efficiencyeng
dcterms.abstractHeat pumps powered by renewable electricity have a significant potential to become a critical technology to disruptively decarbonize an economy. An essential step towards this goal is the development of an accurate understanding and model of how heat pumps in large-scale implementations perform in terms of economics, energy, and the environment. In this study, the influence of system design and operating conditions on the Coefficient of Performance (COP) of large-scale (> 50 kWth) electric driven mechanical compression heat pumps is reviewed, leading to a methodology to estimate a heat pump’s performance depending on the operating conditions. An overview of the potential scale, market size and barriers for large-scale heat pumps with a focus on applications in industry, commerce and district heating systems is given. The review underscores the knowledge gap in the area of large-scale heat pumps including their lack of performance testing standards given the large window of operating conditions as well as meaningful application possibilities. Transferring a significant and reliable dataset to practitioners (e.g. energy-managers and consultants) can close this knowledge gap. Therefore, this study assembles a comprehensive dataset for the system configuration and performance of 33 large-scale heat pumps from 11 different manufacturers and addresses three main objectives: (1) Classifying and evaluating the capabilities of market available heat pumps. (2) Modelling the correlation between the COP and the operating conditions. (3) Developing an economic and ecological evaluation method for a heat pump project. Applying the developed models to accurately assess real-world performance and build a sound business case for large-scale heat pumps has the potential to accelerate the uptake of renewable energy and help improve overall environmental sustainability.eng
