Are all refrigerants harmful to the ozone layer?
Answer:
Typical refrigerants include CFC's, HCFC's' and HFC's.
Those are listed in order if destructiveness to the ozone layer.
If a CFC is 1, an HCFC is 0.05 and an HFC is 0.0.
Not all are identical as regards destructiveness and there are literally dozens of refrigerants and blends to contend with but my statement is roughly correct for the most common varieties.
No
No, all the ones produced today are non destructive. The Harmful CFC's were outlawed ages ago.
not all... now they have invented the Environmental Friendly one
Only Chlro-fluro-carbons (CFC's) are dangerous to the enviroment, according to todays scientists but the long term effects fo very few things is truly known. Science doesn't do a very good job of considering all the risks involved.
No, originally refrigerants were typically chloroflorocarbons that were harmful to the ozone or Ammonia that were highly toxic. Now they are variants that no longer contain the chlorine and are much less toxic and harmul to the Ozone.
