4. Freon - Wikipedia

   en.wikipedia.org/wiki/Freon

   '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 ]

5. File:Temperature-relative humidity chart - PMV method.pdf

   en.wikipedia.org/wiki/File:Temperature-relative...

   The representation is made on a temperature-relative humidity, instead of a standard psychrometric chart. The comfort zone in blue represents the 90% of acceptability, which means the conditions between -0.5 and +0.5 PMV, or PPD < 10%.

6. R-469A - Wikipedia

   en.wikipedia.org/wiki/R-469A

   Thanks to the low GWP value, it fulfils the requirements of EU regulation 517/2014 on refrigerants for new systems even without the certificate of exemption otherwise necessary. Systems using the refrigerant R-469A up to 3.6 kg filling quantity are exempt from the Leak test in accordance with EU regulation 517/2014.

7. R-410A - Wikipedia

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

   R-410A was invented and patented by Allied Signal (later 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 ...

8. 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 ( R-125 ).

9. Working fluid selection - Wikipedia

   en.wikipedia.org/wiki/Working_fluid_selection

   The choice of working fluids is known to have a significant impact on the thermodynamic as well as economic performance of the cycle. A suitable fluid must exhibit favorable physical, chemical, environmental, safety and economic properties such as low specific volume (high density), viscosity, toxicity, flammability, ozone depletion potential (ODP), global warming potential (GWP) and cost, as ...
