Future Optimized Reversible CO2 Chiller and Heat Pump

Heating and cooling is responsible for approximately 50 % of the EU final energy demand which means that it is crucial to address this challenge in order to accomplish climate neutrality in 2050 on both a national level in Denmark and on an European level. By combining of increased energy efficiency, reuse of waste heat and electrification, this project addresses the important challenge of delivering clean and energy efficient heating and cooling for industrial processes and large buildings by combining by a chiller (water chilling packages) and a heating system (heat pump) in a single unit. The main goal of the project is to develop a novel industrial factory-built reversible chiller and heat pump unit based on CO2 as the environmentally friendly and safe natural refrigerant. The target market is both the air conditioning and industrial process market, areas with a huge potential for energy savings and areas playing a potential key role in the green transition. The phase out of fossil fuels in the area of industrial heating is acknowledged by the European Commission to be a main challenge in the transition of our energy system, and this project is considered to be part of the solution.
