The refrigerant is carbon dioxide (CO2), also called R744 in this application. The compressor drives the flow of CO2 through the cycle and raises the pressure above the critical pressure. The gas cooler rejects heat from the high pressure CO2 to the environment.

R744 (Carbon dioxyde) R744, or carbon dioxide, is making its re-entry into the industrial refrigeration scene. Once thought to be a wasteful chemical requiring too much high pressure to be feasible as a coolant, environmentalists now hail R744 as an answer to growing concerns.

Huvudkontor 08-598 908 00. Göteborg 031-49 … R744 is the refrigerant name for carbon dioxide, which will first appear in high-end cars from the big German brands. CO2 requires operating pressures up to ten times higher than R134a. Copeland Stream Semi-Hermetic CO₂ Compressors. Ideal for R744 medium temperature cascade and booster systems, Stream CO2 compressors have a design pressure of 135 bar.

The gas cooler rejects heat from the high pressure CO2 to the environment. r744_safety_data_sheet_darment-1Refrigerant R744, i.e. carbon dioxide (CO2), is an environmentally friendly refrigerant.Its ODP is zero and its GWP is as low as 1, which means that it has even less global warming potential than hydrocarbons. R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications. R744 (CO2) is becoming increasingly popular due to its excellent properties. R744(CO2) Evaporator and gas cooler design Rev.0.0 09.06.2011 2 / 24 systems due to their flammable and explosive nature. The R717 (NH 3, Ammonia) gas on the other hand have such disadvantages as their effects on copper alloys, and the risk of toxicity in large scale systems.

However, sound power spectrum data (Lw) is in accordance to ISO 9614-2. Product Information.

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.
