The portion of ozone killing molecules produced by man is only an extremely
small fraction of what 'mother nature' produces. You must think a lot of
mankind's abilities if you think we have the power to destroy the earth...

For which an impertinent question might be: How is it that all of the
CFC manages to make it to the ozone layer, but none of the far larger
output of ozone from pollution manages to make it there to resolve the
issue?

R-152 is flammable but has fluid properties similar to R-12 which is
why some were promoting it as a replacement for service. OEMs have
rejected this because of the hazard of explosion in the cabin of a
closed car if a leak occurs in an evaporator and the R-152
acccumulates.
R-744 is also known as Carbon Dioxide, it is only poisonous in higher
concentrations. It is not considered a greenhouse gas even though it
has a greenhouse potential... because it is a naturally occurring
substance. The operating pressures are much (10x and more) higher
than R-134a which will drive a complete investent cycle in the
production and service sectors (compressors, heat exchangers,
connecting lines, controls, service equipment etc.). So far the COP
of these systems is slightly better than R-134a leading to reduced
fuel consumption.
As far as following service procedures... come on, be responsible - or
do you still dump drain oil in the back yard to kill the weeds.

R-152 is flammable but has fluid properties similar to R-12 which is
why some were promoting it as a replacement for service. OEMs have
rejected this because of the hazard of explosion in the cabin of a
closed car if a leak occurs in an evaporator and the R-152
acccumulates.
R-744 is also known as Carbon Dioxide, it is only poisonous in higher
concentrations. It is not considered a greenhouse gas even though it
has a greenhouse potential... because it is a naturally occurring
substance. The operating pressures are much (10x and more) higher
than R-134a which will drive a complete investent cycle in the
production and service sectors (compressors, heat exchangers,
connecting lines, controls, service equipment etc.). So far the COP
of these systems is slightly better than R-134a leading to reduced
fuel consumption.
As far as following service procedures... come on, be responsible - or
do you still dump drain oil in the back yard to kill the weeds.
