    CFC's & HCFC's



    .

    Hello all.
    At what point do you think we will not need to teach about CFC’s and HCFC’s?
    All CFC’s have been banned throughout the EU and HCFC’s are controlled so
    effectively banned also. HCFC’s will not legally be used after 2014 so when
    will people not need to know about CFC’s and HCFC’s?

    Are we wasting time teaching about the dangers of Ozone depleting substances?

    Cheers

    Hi Taz24 and All,

    In 2025, you can still run a system with R22, today you can find some installations with R12. It is good to know the harm these gases can suppose to the ozone layer. Avoiding leakages is important then.

    Regards,

    Hi Taz,

    In my opinion, knowledge is never wasted. Engineers may come across an old system charged with CFCs etc. They would need to know about the hazards and also why we now have various blends. (When the engineer is complaining about too many refrigerants!)

    I just wish someone had warned me about the 'joys' of sulphur dioxide, when I encounted an old refrigeration system when I was an apprentice.

    Cheers

    Hey Taz, If it wasn't for history, we could not learn from mistakes, whether or not changes now are for better or worse. In the past, doctors drilled holes in patient's head in the belief it would cure various problems, BUt that was proved basically false. Same goes for our refrigerant history, how it evolved and how it has developed to where it is today. As i said.. for better or for worse.. mike.

    Ok I'll put it another way.

    I'm old enough to remember working with CFC's and I remember
    how little respect we showed to them.

    So...................

    So if twenty years ago we all agreed to make sure CFC's were in gas tight
    systems, just like we do now with HFC's, would we be in the same situation
    now?

    If we had done a Fgas type course twenty years ago and made sure all systems
    were as sound as possible, would the use of CFC's be acceptable?

    All the best

    Hi Taz,

    The fgas regulations aim to minimize the leakages, but these ones exist. the problem of CFCs is that their harm to the environment is much higher, as they attack the ozone layer. CFCs were not only used in RAC as refrigerant gases, but there were many more applications in which these substances were emitted to the ambient.

    Don't know if this answers, at least partially, your doubt.

    Regards,

    Nando.

    Taz, most likely not, that is, as said by Fri3Oil above, many uses of cfc's were used by other companies. Even now, we can't make systems "water tight" as shaft seals, vibration, wear and tear, and these poorly made domestic fridges and freezers will sooner or later drop their gas. I'm sure most of have sniffed conspiracy in the air when it comes down to cfc's being the cause of ozone depletion, however, i'm sure that in 10 years time, the powers to be will find todays gasses are dangerous to fish migration or something along thoes lines. Someone is going to make a stack of money when new changes are enforced.. Mike.
