Alternative kølemidler til køleanlæg

  • Alternative kølemidler til kølekompressorer og kondenseringsaggregater
  • I food retail og kommercielle køleapplikationer, hvor R404A og R134a i dag er de primære kølemidler, som har højt globalt opvarmningspotentiale (GWP), vil R404A blive forbudt i nyt udstyr samt til udskiftning i Europa og USA. Ved at bruge andre teknologier til køling indeholder Danfoss' evalueringsplan for kompressorer alternativer til:

      

    • Danfoss mindre kommercielle køleanlæg: Mange Danfoss-kompressorer er allerede tilgængelige med A3-kølemiddel R290 og A2L-kølemiddel R1234yf. Begge forbedrer kapaciteten og kompressoreffektiviteten sammenlignet med R404A og R134A. For at imødekomme fyldningsgrænsen på 150g for A3-kølemidler, undergår begge A1-blandinger R449A og R452A dog for tiden kvalifikationstests.
    • Danfoss Maneurop reciprocatings: Danfoss Maneurop stempelkompressorer HBP/MBP er allerede kvalificeret til midtvejsopløsningen i R-407A og R-407F men vil nu blive udvidet til også at omfatte R-452A. Dette ekstraordinære erstatningskølemiddel bevarer kompressorernes eksisterende egenskaber og tekniske ydeevne i applikationer ved medium/høje og lave temperaturer og reducerer samtidig GWP med ca. 45%. 
    • Danfoss scroll-kompressorer: Danfoss scroll-kompressorer MLZ and LLZ vil blive kvalificeret til både R448A og R449A. Desuden vil Danfoss MLZ og LLZ platformene blive fuldt ud kvalificeret til R452A blandingen, for at kunne tilbyde en udvidet række af løsninger til R404A udskiftninger.
    • Optyma™ kondenseringsaggregater: Kondenseringsaggregaterne vil være til rådighed til at fungere med de samme kølemidler, som kompressorerne.
