   Författare :Maria Lööf; [2019]
   Nyckelord :;

   Sammanfattning : Supermarket refrigeration systems are large emitters of high GWP refrigerants, and due to the Montreal protocol and F-gas regulation, which aim to phase out high GWP refrigerants, refrigeration systems with alternative refrigerants must be implemented in order to secure climate friendly and efficient refrigeration. One increasingly more popular alternative is transcritical refrigeration systems using only CO2 as a refrigerant. LÄS MER
