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.
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

A refrigerant needs to have: a boiling point that is somewhat below the target temperature (although boiling point can be adjusted by adjusting the pressure appropriately), a high heat of vaporization, a moderate density in liquid form, a relatively high density in gaseous form (which can also be adjusted by setting pressure appropriately), and ...
The dry air produced by heating systems can irritate your nasal passages and throat, which can in turn cause discomfort, Lizarzaburu adds. Dry air can also make it harder to fight off colds.
The common refrigerant R-410A is a zeotropic, 50/50-mass-percent mixture of difluoromethane and pentafluoroethane . Pentafluoroethane is a common replacement for various chlorofluorocarbons (i.e Freon ) in new refrigerant systems, especially for air-conditioning.
Use an air purifier, or an air conditioner that pulls in inside air and has an up-to-date, effective air filter. If your air purifier is small, run it in a smaller room and say in there as much as ...
