Can the ozone depleting freon gas, used frequently in car ACs be substituted?

Question

The FREON gas called Dichloro difluoro methane CCl2F2, is one of the main gases causing ozone depletion. though there is so much danger we are still seeing it used in all the carAC's and refrigerators.but just for the hope of any recovery in future is there any effective harmless substitution for this indispensable gas ?

Answer 1

r-12 was replaced with r 134 back in 1990, and no it wasnt cc12f2 that was the alleged main culprit, it was cfc's ( chlorofluorocarbon) that was used as a propellant in making things like aerosol cans among others.also freon only works inside a closed system, meaning if the freon leaked out,you called the a/c repair people. the number of units that would have to leak freon to cause the same amount of damage as cfc's  would equate to approximately 400 million units, a/c condensers usually only run a cpl pounds of refrigerant freon, and many of the refrigerators now used an ammonia based refrigerant,that merely evaporates and smells bad if leaked. these units have been in use for at least 40 years already in large commercial grade freezers

Answer 2

The CFC are not affecting the ozone layer. It is so high that most gases can not get there. Now look at the weight of of the CFC's. It is much too heavy. The ozone layer is at the very edge of space . What makes the ozone layer is where the solar winds and the earth's magnetic field collide. It is much more complicated than that but it is not the CFCs.

Answer 3

it already is. with HFCs but another alternative could be ammonia.

Answer 4

They took CFC's out several years ago and the replacement isn't at effective.  CFC's were never proven to cause damage to the ozone.  Just another hoax.
