  • KTH researchers supporting hydrocarbons as refrigerants in heat pumps

    KTH researchers take the lead on Position Paper supporting hydrocarbons as refrigerants in heat pumps

  • Tank to Grave Management of new Low-GWP Refrigerants (Hantering av nya låg-GWP köldmedier från installation till destruktion)

    The project “Tank to Grave Management of new Low-GWP Refrigerants” is a project funded within the Termo program (heating and cooling for future energy systems), the 5th funding call (contributing to a Sustainable Energy System through Heating and Cooling) by the Swedish Energy Agency.

  • EcoPack 3

    Synthetic refrigerants with high GWP are being substituted in refrigeration and heat pump systems for highly flammable hydrocarbons. To maintain safety with these fluids it is essential that the charge of refrigerant is low. EcoPack3 is the third in a series of projects where we develop heat pump components and systems with low charge. We have demonstrated the design of a heat pump with 12 kW capacity using only 120g of isobutane as refrigerant. This has been achieved by using very compact heat exchangers and the type of compressors used in electric cars.
