Critical temperature in degrees Celsius; Absolute critical pressure in kilopascals; Since over 100,000 refrigerant blends are possible, [2] this list should only have notable refrigerants and refrigerant blends.
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.
Promoted as climate-friendly substitute for R-134a and R-410A, but still with high climate impact. Has excellent heat transfer and pressure drop performance, both in condensation and vaporisation. [61] It has an atmospheric lifetime of nearly 5 years. [62] Currently used in residential and commercial air-conditioners and heat pumps. R-134a HFC ...
1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
As a result of CFCs contributing to ozone depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol, and they are being replaced with other products such as hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs) [1] including R-410A,R-134a and R-1234yf.
A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
'Freon' is the brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company, and so is not used to label all refrigerants of this type. They emit a strong smell similar to acetone. [2] Freon has been found to cause damage to human health when inhaled in large amounts.
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.
