Die Bedeutung von CO 2 für Kälteanwendungen hat in den letzten Jahren zugenommen und der Markt fokussiert sich zunehmend auf das Kältemittel R744. CO 2 ist ein natürliches Kältemittel und im Vergleich zu den fluorierten Kältemitteln umweltfreundlich und kostengünstig. Es ist nicht brennbar, nicht toxisch und farblos.

It is ever more likely that CO2 (carbon dioxide) will be the refrigerant used by many manufacturer’s in the near future. Daimler (owner of the Mercedes brand) and the VAG group are already using CO2 in some of their models and it is thought it could become the way forward for many others. Why CO2 (R744) in air R744 (CO2) Freezer.

Concerns regarding traditional and widely used chemical refrigerants R744 is the refrigerant name of CO2, (Carbon Dioxide), and is a natural gas which is all around us. In fact, we even cannot live without it! But as with anything, adding too much to our environment while the demand of the natural use from nature, is rapidly decreasing by cutting down forests, ( also for the use of fire wood and fuel pellets! r744_safety_data_sheet_darment-1Refrigerant R744, i.e. carbon dioxide (CO2), is an environmentally friendly refrigerant.

This provides contractors and end users a robust construction with compact dimensions. Utilising 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. Danfoss shut-off ball valves, type GBC for CO2 are manually operated shut-off valves only for single-flow direction.
