DeCarbCH Lunch Talk: Industrial Heat Pumps presented by Cordin Arpagaus

SWEET DeCarbCH Lunch Talk given on the 9th November 2021. The video is the live recording of the talk. Industrial Heat Pumps – State-of-the-Art in Research and Market, presentation given by Cordin Arpagaus (OST) Cordin Arpagaus webpage: https://www.ost.ch/de/person/cordin-a... "Heat pumps in industry enable increased energy efficiency and drive decarbonization to ensure a reliable heating and cooling supply. Moreover, they represent an environmentally friendly and economically attractive alternative to conventional heating systems thanks to their efficiency. Therefore, large heat pumps are attractively used in district heating networks of municipalities and industrial heat pumps mainly in waste heat recovery. The first part of this lunch talk gives an overview of industrial heat pump technologies already on the market and also provides guidance to best select and plan the installation. The major barriers are discussed, and numerous realized application examples of integrated industrial heat pumps from Switzerland are presented. The second part is about the research activities in the field, in particular: steam generating heat pumps, heat pumps with synthetic HFO refrigerants, heat pumps with refrigerant mixtures for large temperature glides, transcritical heat pumps, heat pumps with inert gases, and heat pumps for both heating and cooling. The advantages and disadvantages of each technology are discussed. Finally, some related research projects at OST will also be shown."
