Which refrigerant group effects the ozone layer?

Which refrigerant group effects the ozone layer?

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. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.

Which refrigerants causes ozone depletion?

The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS).

How can a refrigerant cause the breakup or depletion of the ozone layer?

Refrigerants containing chlorine or bromine contribute to the breakdown of the ozone layer (see Figure 5.1). The reaction is as follows: However, the CIO molecule is unstable. It breaks down and reacts with ozone molecules (in accordance with the equation above) repeatedly until a more stable compound is created.

How do refrigerants harm the environment?

Refrigerants cause damage to the ozone layer and contribute to global warming, and while there have been some efforts to reduce the impact, a climate-friendly refrigerant is yet to be discovered. …

Why do refrigerants cause global warming?

These refrigerants break down ozone molecules far less, but are extremely potent greenhouse gases. This is because HFCs and HCFCs – along with CFCs – also absorb infrared radiation, trapping heat inside the atmosphere rather than allowing it to escape back into space, creating a greenhouse effect that warms the planet.

What is conclusion of global warming?

The ‘Conclusion’ confirms that global warming is the major challenge for our global society. There is very little doubt that global warming will change our climate in the next century. If implemented now, a lot of the costs and damage that could be caused by changing climate can be mitigated.
