Chlorofluorocarbons (CFCs) are no longer used in air conditioning systems due to their harmful effects on the ozone layer. The Montreal Protocol, established in 1987, phased out the production and use of CFCs and other ozone-depleting substances. Modern air conditioning systems now primarily use alternatives like hydrofluorocarbons (HFCs) or natural refrigerants, which are less harmful to the environment.
What else can I help you with?
Where is CFC in ac?
CFC, or chlorofluorocarbons, are typically found in air conditioning units as refrigerants. These compounds have been widely used in the past, but are being phased out due to their harmful impact on the ozone layer. Modern air conditioning systems now use alternative refrigerants that are more environmentally friendly.
What are the sources of cfc's in the atmosphere?
the source of cfc is mainly from refrigerators n ac's...increase in the emission of cfc may lead to a hole in the ozone layer,the result of which is harmful rays such as ultra violet rays reaching out to people which causes skin cancer
What is an example of CFC refrigerant?
The example of CFC is R-12. It is being used as a refrigerant.
What is earths ozone layer is being damaged by?
CFC's chlorofluorocarbons
How many CFC's are used each year?
CFC amount has been growing over the years. They do destroy ozone very much.
How many cfc molecules are being liberated on an average in one hour from an ac?
An Air Conditioner releases CFC's. A CFC can destroy large number of ozone molecules.
How many cfc molecules are liberated by an ac?
CFC's are liberated from AC's. They are one of the main source. CFC's damage the ozone significantly.

Which compound is causing ozone depletion in Antarctica?
Chlorine is the element and CFC is the compound. They are built as refrigerating compounds. These compounds are used in AC's, Deodorants etc.The compound causing ozone depletion is CFC. They are chemicals of Fluorine. They form oxides with ozone.CFCs (chlorofluorocarbons).
What was a key design change for HFC-134a AC systems versus CFC-12 AC systems?
A key design change for HFC-134a AC systems compared to CFC-12 systems was the need for different materials and components to accommodate the properties of HFC-134a. HFC-134a operates at higher pressures than CFC-12, necessitating stronger hoses, seals, and components to prevent leaks and ensure reliability. Additionally, the lubricant used in HFC-134a systems had to be changed from mineral oil, typically used with CFC-12, to synthetic oils that are compatible with the new refrigerant.
How are they CFC used?
CFC are used as coolants. They react with ozone and deplete it.
What was a key design change for HFC-134A ac system versus CFC-1 AC SYSTEM?
electric compressors
What are the sources of cfc's in the atmosphere?
the source of cfc is mainly from refrigerators n ac's...increase in the emission of cfc may lead to a hole in the ozone layer,the result of which is harmful rays such as ultra violet rays reaching out to people which causes skin cancer
How many AC companies are making CFC free ACs?
As I think now mostly all companies are making CFC free ACs but most promptly the companies like Daikin & BlueStar are making CFC free ones..
What is an example of CFC refrigerant?
The example of CFC is R-12. It is being used as a refrigerant.
What produces substances that pollutes the ozone layer?
AC's etc produce that substance. The substance is CFC's.
What is the alternative solution for destroying ozone molecules by using AC?
There is an alternate solution for CFC's. These are HCFC's.
