Q. Which types of refrigerants will not damage stratospheric ozone?
R-134a. HCFC refrigerants: Are less harmful to stratospheric ozone than CFCs.
Q. What refrigerant damage does stratospheric ozone do?
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun.
Q. Which refrigerant depletes the ozone layer?
HCFCs
Q. Does Freon affect the ozone layer?
Freon is the general name, and chemical name is Fluoric-carbon (chemical materials bonding Fluoride and carbon), among which CFC (Chloro-fluoric Carbon: designated Freon) and HCFC (Hydro Chloro-fluoric carbon: designated Freon) destroy Ozone layer in space.
Q. Do air conditioners deplete the ozone layer?
Did you know that the refrigerants contained in air-conditioners and refrigerators can be extremely harmful to the environment? Many refrigerants, such as chlorofluorocarbons (CFCs) damage the ozone layer, while others are extremely potent greenhouse gases.
Q. How do they destroy the ozone layer?
Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.
Q. Is there a ozone layer?
The ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth’s atmosphere as a whole is about 0.3 parts per million.
Q. What is the function of stratospheric ozone?
Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. This is typically regarded as ‘good’ ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth’s surface.
