Which one is the non ozone-depleting refrigerant?

The most common alternative to R-22 is R-410A, a non-ozone-depleting HFC refrigerant blend. R-410A is manufactured and sold under various trade names, including GENTRON AZ-20®, SUVA® 410A, and PURON®.

Which gases does not deplete ozone layer?

F-gases include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These gases do not deplete the ozone layer, but they are greenhouse gases. This means that these new gases also contribute to climate change.

Which are the ozone-depleting substances?

This page provides information on compounds recognized as ozone-depleting substances ( ODS. ODS include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform.

What is HCFC used for?

HCFCs were used in a wide variety of applications, including refrigeration, air conditioning, foam blowing, solvents, aerosols, and fire suppression. Although 34 HCFCs are subject to the phaseout, only a few were commonly used.

What is HFC refrigerant?

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.

What are CFC and HCFC refrigerants?

The key difference between CFC and HCFC is that the CFC contains only carbon, fluorine and chlorine atoms whereas HCFC contains hydrogen, carbon, fluorine and chlorine atoms. More importantly, CFC causes serious ozone depletion but HCFC, comparatively, has a much lesser impact on the ozone layer.

Does co2 deplete ozone layer?

Carbon dioxide causes depletion of ozone layer thereby allowing more UV-radiations to reach the earth.

Which of the following compounds is not involved in the depletion of stratospheric ozone?

So, CH4 does not contain a halogen therefore it is not responsible for the depletion of ozone layer.

What is one example of ozone depletion?

One example of ozone depletion is the annual ozone “hole” over AntarcticaExit Exit EPA website that has occurred during the Antarctic spring since the early 1980s. This is not really a hole through the ozone layer, but rather a large area of the stratosphere with extremely low amounts of ozone.

Which are the following gases is responsible for depletion of ozone layer?

Detailed Solution. The correct answer is CFCs. Chlorofluorocarbons (CFCs) are mainly responsible for ozone layer depletion.

What is the difference between HCFC and HFC?

HCFC refers to hydrochlorofluorocarbon, while HFC refers to hydrofluorocarbon. The key difference between HCFC and HFC is that HCFC contains chlorine and can cause harm to the ozone layer, whereas HFC is free of chlorine and does not harm the ozone layer.

What is the difference between CFC and HCFC?
