Cons. While R-744 is the ‘perfect’ natural refrigerant in theory there are a lot of downsides. R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications.

While R-744 is the ‘perfect’ natural refrigerant … The term R744 refers to CO 2 when it is used as natural refrigerant in the refrigeration and air conditioning industry. R744 CO 2 has excellent thermodynamic properties and has significant advantages compared to classical and other alternative refrigerants: R744 refrigerant properties: CO 2 is non-corrosive, non-toxic and non-flammable First, to facilitate this moment of transition, ISA offers solutions with natural refrigerants at the same price as those with traditional systems.

Purity and moisture Moisture in R744 based refrigeration and air conditioning systems will create carbonic acid. This acid then causes corrosion in the steel pipe work. There is also a risk of ice formation that can block small capillary Details. Original title: R744 (CO 2 / Carbon Dioxide): Thermophysical Properties.
