2. R-410A - Wikipedia

   en.wikipedia.org/wiki/R_410a

   R-410A was invented and patented by Allied Signal (now Honeywell) in 1991. [5] Other producers around the world have been licensed to manufacture and sell R-410A. [6] R-410A was successfully commercialized in the air conditioning segment by a combined effort of Carrier Corporation, Emerson Climate Technologies, Inc., Copeland Scroll Compressors (a division of Emerson Electric Company), and ...

3. Pentafluoroethane - Wikipedia

   en.wikipedia.org/wiki/Pentafluoroethane

   Shipping container for the gas, shown in Japan 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.

4. List of refrigerants - Wikipedia

   en.wikipedia.org/wiki/List_of_refrigerants

   For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This ...

5. Freon - Wikipedia

   en.wikipedia.org/wiki/Freon

   Chlorodifluoromethane (R-22 or HCFC-22), a type of Freon. [9] [10] Dichlorodifluoromethane (R-12 or CFC-12), the most commonly used Freon brand refrigerant prior to its ban in many countries in 1996 and total ban in 2010. 1,1,1,2-Tetrafluoroethane (R-134a or HFC-134a), one of the main replacements for the formerly widespread R-12.

6. Difluoromethane - Wikipedia

   en.wikipedia.org/wiki/Difluoromethane

   The zeotropic mix of difluoromethane with pentafluoroethane and tetrafluoroethane is known as R-407A through R-407F depending on the composition. Likewise, R-504 is the azeotropic (48.2/51.8 mass%) mixture of difluoromethane and chlorotrifluoromethane (R13). In 2011 17,949,893 metric tons of difluoromethane were emitted into the atmosphere in ...

7. Polyolester - Wikipedia

   en.wikipedia.org/wiki/Polyolester

   Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12. [1] POE oils are used as a lubricant in systems using the refrigerant HFC-134a when replacing CFC-12 , as these systems traditionally use mineral oil , [ 2 ] which HFC-134a does not ...

8. R-454B - Wikipedia

   en.wikipedia.org/wiki/R-454B

   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 ...

9. California Balloon Law - Wikipedia

   en.wikipedia.org/wiki/California_Balloon_Law

   The balloon law prohibits the sale or distribution of a balloon that is constructed of electrically conductive material (metallized Mylar or foil) and filled with a gas lighter than air (helium), without affixing an object of sufficient weight to the balloon to counter the lift capability, affixing a specified warning statement on the balloon ...
