R-410A is a refrigerant used in air conditioning and heat pump applications. It is a zeotropic but near-azeotropic mixture of difluoromethane (CH 2 F 2, called R-32) and pentafluoroethane (CHF 2 CF 3, called R-125). R-410A is sold under the trademarked names AZ-20, EcoFluor R410, Forane 410A, Genetron R410A, Puron, and Suva 410A.
Normal boiling points for pure substances, bubble and dew points for zeotropic blends, or normal boiling point and azeotropic temperature for the azeotropic blends, at 101,325 Pa (1 atmosphere) and in degrees Celsius; Critical temperature in degrees Celsius; Absolute critical pressure in kilopascals
Pentafluoroethane in a near azeotropic mixture with difluoromethane is known as R-410A, a common replacement for various chlorofluorocarbons (commonly known as Freon) in new refrigerant systems. Fire suppression systems

If the temperature and pressure are both increased from STP to be at or above the critical point for carbon dioxide, it can adopt properties midway between a gas and a liquid. More specifically, it behaves as a supercritical fluid above its critical temperature (304.128 K, 30.9780 °C, 87.7604 °F) [1] and critical pressure (7.3773 MPa, 72.808 ...
Methane, the second most important greenhouse gas after carbon dioxide is 28, or 28 times worse. The common refrigerant known as R-410A, has a global warming potential of 2,088.
In other words, the mixture has a temperature glide, as the phase change occurs in a temperature range of about four to seven degrees Celsius, rather than at a constant temperature. [3] On temperature-composition graphs, this temperature glide can be seen as the temperature difference between the bubble point and dew point . [ 4 ]
