led to the revival of R744 in parts of the European refrigeration market. Regionally, this trend is reinforced by legislation and taxation schemes which favor the usage of refrigerant R744. In comparison with HFC refrigerants, the specific properties of R744 require changes in the design of the refrigeration system.

Kylmedel: R744. KYLNINGSKAPACITET (kW): MT: upp till 480, LT: upp till 94. Beskrivning: Kompressorrack + högeffektssläde, multikompressor, CO₂, MT & LT

It covers all refrigeration and heating and cooling applications. R744 CASCADE SYSTEM SCHEMATIC - LOW PRESSURE SIDE The SER and SERI valves shown in the scheme can be driven with a PSD4 (Superheat Controller) or, as the CDS valves, through the IB-G Board. NOTE This is only a theoretical scheme so some components could not be shown. All components must be properly pressure rated and protected for safe In the second part of this report, a theoretical comparison of R744 and R410A is made.
