European heat pump market data – Evolution of the state of the art heat pump over time and its possible knowledge gain.

Author(s) : OLTERSDORF T., FUGMANN H., SCHNABEL L.

Summary

Market data for several thousand heat pumps are available in different databases in Europe. Information therein of different versions over time allow the analysis of the evolution of the state of the art of heat pumps. Contrary to typical investigations of single systems by research groups as kind of “bottom-up approaches” to develop new systems or to argue why a specific refrigerant might be applicable due to reached efficiency etc., we try to gain insights into the state-of-the-art of the European heat pump market with a “top-down approach”. The study begins with a comparison of such available databases and their specific differences. The gained product data are aggregated with additional information usually not part of such databases like the age of equipment, dimensions, etc. Thereby a very comprehensive new database arises. Based on this database we show the course over time of important parameters, such as used refrigerants and efficiency, but also sound emissions and refrigerant charge. Where possible the analysis comprises sensitivity analysis of different parameters linked to the used refrigerants and impacts of the applied refrigerant’s thermodynamics.
