Weighing the Advantages and Disadvantages of R744 Table 1 outlines the advantages and disadvantages of R744 as a refrigerant. The list of disadvantages appears smaller than the advantages list, but these issues should not be overlooked, as they have a significant impact on the safety and reliability […] conditioning technologies. Industry sponsors include Bitzer, Austral, Danfoss, Carel, Heatcraft, GEA (Grasso), Alfa Laval, Guntner, Scantec and Minus40. As a refrigerant, CO 2 (R744) has the significant advantages of having the lowest GWP, a very low refrigerant cost and excellent heat transfer.

2015-05-14 · Solid R744 (also known as dry ice) has a surface temperature of -78.5 °C (-109.3 °F). If R744 is at a pressure higher than the triple point and the pressure is reduced to below the triple point (e.g., to atmospheric pressure), it will deposit directly to solid.
