Efficient and Quality Service Gas & Related Equipment Know How Transcritical CO2 (R744) Refrigeration Cycle. This example models a vapor-compression refrigeration cycle in which the high pressure portion of the cycle operates in the supercritical fluid region. The refrigerant is carbon dioxide (CO2), also called R744 in this application.
R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications. With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant. R744 (Koldioxid) R744 är miljövänlig och har varken ozonnedbrytande potential (ODP) eller global uppvärmningspotential (GWP). Det har även utmärkta termodynamiska egenskaper och låg energianvändning gör den lämplig för en rad olika tillämpningar såsom industriell värmeåtervinning, kyld lagring, fraktfartyg, kommersiell kylning och mobil luftkonditionering.
