When will be illegal to vent substitutes for CFC and HCFC refrigerants?
Since November 15, 1995
Which refrigerant will not damage ozone?
HCFC's are being used nowadays. These are the refrigerants that do not damage ozone.
Appliances containing cfc refrigerant can be evacuated to atmopheric pressures when?
Small appliances containing HCFC refrigerants can be evacuated to atmospheric pressure when leaks make evacuation to the prescribed level unreachable. HCFC stands for hydrochlorofluorocarbons.
Which substance is used as a coolant in ice-cream factories?
Factories us giant industrial compressor freezers using HCFC refrigerants.
How do you pronounce chlorofluorocarbons?
Pronounced "KLOR-oh-FLOR-oh-kar-bunz" (mostly fluoromethane refrigerants such as Freon, abbreviated CFC's; along with hydrochlorofluorocarbons, HCFC's, they are implicated in upper atmospheric ozone destruction)
Are there any fluorocarbon refrigerant that cause no harm to stratospheric ozone?
No fluorocarbon refrigerants pose harm to the ozone layer. Only molecules with chlorine or bromine pose a hazard.
How does hcfc destroy ozone layer?
HCFC do not destroy ozone. They are an alternative to CFC's.
What is inorganic refrigerants?
Inorganic refrigerants are refrigerants that are not organic
What are the characteristics of CFC and HCFC refrigerants and how do these refrigerants contribute to ozone depletion?
They were made and used because they are extremely stable, they had useful gas-to-liquid transition temperatures, and they were cheap (fluorine production is dirty, dangerous, and hence expensive). They contribute to ozone depletion because they are so stable they can only be brokne down in the intense radiation of the ozone layer, and their chlorine payload is released to do its dirty deed over and over.
Cfc and hcfc refrigerants cause suffocation because?
Because it is more dense than the air we breathe so it sits in your lungs and doesn't allow atmospheric air in. If you were to turn upside down, this should allow the CFC to escape your lungs allowing you to breathe again.
What does HCFC stands for?
HydroChloroFluoroCarbon
Why is an HCFC refrigerant considered less harmfull to the ozone than a CFC refrigerant?
An HCFC refrigerant can be attacked biologically, keeping the "CFC" portion of the HCFC from reaching the region of the atmosphere where UV will make it a depleter
