Which type of refrigerant is the most harmful to stratospheric ozone quizlet?

Which type of refrigerant is the most harmful to stratospheric ozone quizlet?

Which type of refrigerant is the most harmful to stratospheric ozone? Refrigerants containing Bromine. Non-Azeotropic refrigerants leak from a system: In uneven amounts due to different vapor pressure.

Which type of refrigerant is the most harmful to stratospheric ozone a CFCs B HCFCs C HFCs D HFOs?

CFCs have the highest ozone depletion potential of all the types of refrigerants because of the three chlorine atoms it contained. HFCs and HFOs are non ozone depleting since they do not have chlorine atoms. They both have an ODP of 0. But CFCs and HCFCs, contain chlorine atoms.

Which refrigerant is known to destroy ozone?

Chlorofluorocarbons (CFCs) are a class of chemical refrigerants that destroy the ozone layer and warm our planet. They are both ozone depleting substances (ODS) and potent greenhouse gases (GHGs).

Which refrigerants have the highest ozone depleting potential?

Ozone-depletion potential (ODP) is a measurement of a refrigerant’s ability to destroy ozone. Stated simply, refrigerants with chlorine have an ODP, while those without chlorine don’t. CFCs have the highest ODP, followed by HCFCs.

Which refrigerant has the lowest global warming potential r134a r407c r410a r600a?

The refrigerant with the lowest GWP (Global Warming Potential) is R-717.

What is ODP HVAC?

Ozone Depletion Potential (ODP) is the ratio of ability of a substance to degrade ozone, to that of chlorofluorocarbon-11 (CFC-11).

How is good stratospheric ozone formed?

Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.

Is stratospheric ozone harmful?

Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. Ground-level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma.

Which refrigerant is known to destroy ozone Brainly?

Molina discovered that chlorofluorocarbons (CFCs) could deplete Earth’s atmospheric ozone layer, which blocks the sun’s damaging ultraviolet rays. When the scientists reported their findings in 1974, CFCs were widely used as refrigerant gases and as propellants in aerosol sprays.

Which refrigerant has lowest ozone depletion?

R-717 goes by the trade name Ammonia, which has been around since the 1930s. Experts today recognize it as the most efficient refrigerant in the world. In addition to its 0 GWP, R-717 has a 0 Ozone Depletion Potential as well.

Which refrigerant has the highest global warming potential?

The most common refrigerant today, R-22, has a 100-year GWP of 1,810, almost 2,000 times the potency of carbon dioxide, so just one pound of R-22 is nearly as potent as a ton of carbon dioxide.

What are HFC refrigerants?

HFC Refrigerant: HFC refers to the chemical composition of the refrigerant. Hydrofluorocarbon indicates that the refrigerant is comprised of Hydrogen, Fluorine, and Carbon. Common HFC refrigerants are R-32, R- 125, R134a, R-143a, and R-152a. A blend that contains different HFCs is considered an HFC refrigerant.
