  2. 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.

    Refrigerant concentration limit / immediately dangerous to life or health in parts per million (volume per volume) and grams per cubic meter Molecular mass in atomic mass units 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 ...

  4. Difluoromethane - Wikipedia

    en.wikipedia.org/wiki/Difluoromethane

    Difluoromethane is thus a relatively low-risk choice among HFC refrigerants, most of which have higher GWP and longer persistence when leaks occur. The common refrigerant R-410A is a zeotropic, 50/50-mass-percent mixture of difluoromethane and pentafluoroethane .

  6. Zeotropic mixture - Wikipedia

    en.wikipedia.org/wiki/Zeotropic_mixture

    In mixtures of substances, the bubble point is the saturated liquid temperature, whereas the saturated vapor temperature is called the dew point. Because the bubble and dew lines of a zeotropic mixture's temperature-composition diagram do not intersect, a zeotropic mixture in its liquid phase has a different fraction of a component than the gas ...

  7. Pentafluoroethane - Wikipedia

    en.wikipedia.org/wiki/Pentafluoroethane

    Pentafluoroethane is a fluorocarbon with the formula CF 3 CHF 2. Pentafluoroethane is currently used as a refrigerant (known as R-125) and also used as a fire suppression agent in fire suppression systems. Pentafluoroethane does not deplete ozone so it has replaced earlier fluorinated chemicals that did.

  8. Frigorific mixture - Wikipedia

    en.wikipedia.org/wiki/Frigorific_mixture

    Liquid water and ice, for example, form a frigorific mixture at 0 °C or 32 °F. This mixture was once used to define 0 °C. That temperature is now defined as the triple point of Water with well-defined isotope ratios. A mixture of ammonium chloride, water, and ice form a frigorific mixture at about −17.8 °C or 0 °F.

  9. Heat pump and refrigeration cycle - Wikipedia

    en.wikipedia.org/wiki/Heat_pump_and...

    Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
