    en.wikipedia.org/wiki/1,1,1,2-Tetrafluoroethane

    1,1,1,2-Tetrafluoroethane is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more environmentally harmful R-12. Retrofit kits are available to convert units that were ...

R-134a HFC-134a CH 2 FCF 3: 1,1,1,2-Tetrafluoroethane: 3790 1550 Widely used Most used in 2020 for hydronic heat pumps in Europe and the United States in spite of high GWP. [58] Commonly used in automotive air conditioners prior to phase out which began in 2012. R-410A

  6. R-410A - Wikipedia

    en.wikipedia.org/wiki/R-410A

    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.

  7. Cooling capacity - Wikipedia

    en.wikipedia.org/wiki/Cooling_capacity

    Cooling capacity is the measure of a cooling system's ability to remove heat. [1] It is equivalent to the heat supplied to the evaporator/boiler part of the refrigeration cycle and may be called the "rate of refrigeration" or "refrigeration capacity".

  8. Air conditioning - Wikipedia

    en.wikipedia.org/wiki/Air_conditioning

    Air conditioning can be achieved using a mechanical 'air conditioner' or by other methods, including passive cooling and ventilative cooling. [ 2 ] [ 3 ] Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC) . [ 4 ]

  9. R-407C - Wikipedia

    en.wikipedia.org/wiki/R-407C

    R-407C is a mixture of hydrofluorocarbons used as a refrigerant. It is a zeotropic blend of difluoromethane (R-32), pentafluoroethane (R-125), and 1,1,1,2-tetrafluoroethane (R-134a). Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. [1] R-407C cylinders are colored ...
