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.
The energy efficiency and system capacity of systems designed for R-22 is slightly greater using R-22 than the available substitutes. [11] R-407A is for use in low- and medium-temp refrigeration. Uses a polyolester (POE) oil. R-407C is for use in air conditioning. Uses a minimum of 20 percent POE oil.
If there is more than one carbon atom but no multiple bonds, there are three digits, and the number of carbon atoms minus one is the first digit. If there is only one carbon atom, then there are only two digits. The last two digits are always the number of hydrogen atoms plus one (H+1), followed by the number of fluorine atoms.
I have repaired the formula for HFC-125 there. Also it is not clear what th global warming potential of R-410A is at all, since it is a 50% mixture of HFC-32 and HFC-125 [1]. Accordingly the claim that "R410A has a high global warming potential (GWP) of 2088, higher than that of R-22 (GWP=1760), and an atmospheric lifetime spanning decades.
'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 ]
An easy example is that of CFC-12, which gives: 90+12=102 -> 1 carbon, 0 hydrogens, 2 fluorine atoms, and hence 2 chlorine atoms resulting in CCl 2 F 2. The main advantage of this method of deducing the molecular composition in comparison with the method described in the paragraph above is that it gives the number of carbon atoms of the molecule.
High Efficiency: Provides effective cooling with good energy efficiency. Environmentally Friendly: Does not deplete the ozone layer, making it a more sustainable option than its predecessors. Equipment Compatibility: Generally compatible with R22 system components, though some adjustments may be necessary for optimal performance.
Because of its reduced global warming potential (GWP), R-454B is intended to be an alternative to refrigerant R-410A in new equipment. [2] [3] [4] R-454B has a GWP of 466, which is 78 percent lower than R-410A's GWP of 2088. [2] R-454B is non-toxic and mildly flammable, with an ASHRAE safety classification of A2L. In the United States, it is ...
