New green cooling technology

CARA Cooling is currently testing a new, innovative cooling technology at DTU Risø. The project demonstrates how surplus heat, for example from district heating, can be used to produce cooling without any use of electricity. Instead of traditional refrigerants, the system uses water that evaporates at low pressure and drives a turbine that creates cooling power.

“This solution can reduce CO₂ emissions by up to 80% and significantly lower operating costs compared to traditional cooling systems. The technology is safe, requires minimal maintenance and can be implemented in industry, data centres and buildings,” says Henrik Schiøtt Sørensen, Chief Scientific Officer and co-founder of CARA Cooling.

By utilising surplus heat that would otherwise be wasted, the solution by CARA Cooling relieves the electricity grid and creates a more sustainable energy future.

“Thanks to the support from the Vissing Foundation, we will carry out a project at DTU Risø to test a cooling unit and develop a new turbo compressor that will make the system even more efficient. The goal is to prove the potential of the technology and pave the way for future, green cooling solutions,” says Jan Laisen, CEO and co-founder of CARA Cooling.
