What are chlorofluorocarbons (CFCs) primarily used for?

Chlorofluorocarbons (CFCs) are primarily used as refrigerants and coolants in a variety of applications, particularly in refrigeration and air conditioning systems. Their chemical properties make them effective at transferring heat, which is essential for cooling processes. CFCs are known for their stability and non-flammability, which contributed to their widespread use in domestic and commercial refrigeration systems, as well as in aerosol propellants in the past.

While other uses of CFCs exist, such as in foam-blowing agents and solvents, their predominant application has historically been in refrigeration and air conditioning. Understanding the role of CFCs in these systems is crucial, especially considering the environmental impact associated with their release into the atmosphere, which has led to significant regulatory changes and the phase-out of many CFCs due to their contribution to ozone layer depletion.
