Cooling and Heat Recovery at the Max IV Research Facility

Explore how the energy needs of the MAX-lab research facility led to innovative cooling and heat recovery strategies. The demand for heating, cooling, and air conditioning was efficiently met by utilizing excess heat for internal heating and cooling processes. Energy mapping, heat pumps, and district heating were key components in maximizing heat recovery potential. The collaboration with an efficient energy partner ensured cost-effective and sustainable energy solutions.

  1. Cooling and Heat Recovery at the Max IV Research Facility

  2. Background • The starting point was the need of energy for MAX-lab research facility. • It was clear that MAX-lab was going to use a lot of electricity to run its equipment… • … but what about heating, cooling and air condition?

  3. Background Max-labneedsbothheatingand cooling. The demandswheredividedintothreegroups: Heating Process cooling Comfort cooling 24 C 34 C 7 C 15 C

  4. Background Can’t we just use some of our excess heat to internal heating? Heating Process cooling Comfort cooling 24 C 34 C 7 C 15 C
