Dichlorodifluoromethane (R-12) is a colorless gas popularly known by the genericized brand name Freon (as Freon-12). It is a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant .
This refrigerant is intended as a replacement for R-22. R-22 production will be phased out by 2020 as per the Montreal Protocol. [2] Key Characteristics: Colourless and Odourless: R407C is visually clear and does not emit a noticeable smell. Non-Flammable: Safe to use under normal operating conditions due to its non-flammable nature. [3]
Dichlorofluoromethane or Freon 21 or R 21 is a halomethane or hydrochlorofluorocarbon with the formula CHCl 2 F. It is a colorless and odorless gas. It is a colorless and odorless gas. It is produced by fluorination of chloroform using a catalyst such as antimony trifluoride : [ 4 ]
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
One of the worst home smells is a putrid-smelling refrigerator. While it most of the time comes from left behind spoiled foods, there are other reasons why your smell might smelly funky. Bacteria ...
Freon tanks awaiting CFC reclamation and container recycling in 2012 While new production of these refrigerants has been banned, large volumes still exist in older systems and have been said to pose an immediate threat to our environment. [ 56 ]
Barring any other external factors, freezer burnt food should be safe to eat. The scientific process that creates the ice crystals, known as sublimation , draws out the moisture from your food and ...
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 ...
