So your argument is that CFCs such as R-12 don't interact with the
ozone layer and hasten its demise? I would say that there's a lot of
well established science that would argue with you.



America has gotten rid of R-12 for many many years. The ozone hole is
bigger.

I'm not saying that R-12 isn't a terrible chemical capable of
destroying ozone in the laboratory, where, of course at great expense,
all these facts fester. What I'm OBSERVING is that the effect of
dragging America, at 10 to 15 times the price, into R-134a has
been....well......ZERO, just like most other programs designed to
separate the American consumer from his wealth by the corporate
government bureaucrats.

Why don't you convert you R-12 system to R-134A? Many systems have been
converted? The fact that you're aware of the price of R-12 indicates that
your system leaks. R-134A is as cheap, or cheaper, than R-12.

You may chose to run systems (such as autos) that utilize out-moded
technology, but you do so at a price, as when you go to repair those
systems, you can't obtain replacment parts (such as R-12) at a reasonable
price. This is simply part of your cost "savings" associated with using old
technology.

Yea, NOW at todays Prices for R12..... But it is many more times as
expensive than R12 was, when the "Greenies" forced it off the Market.....

All this babble regarding the best refrigerant is Wilburly. The only
true and best refrigerant is ammonia. Any one use anything else on a
yacht under 65' is ignorant.

With a small engine like mine and modest electric loads otherwise, wouldn't
it me more efficient to put the largest compressor that a toothed belt pully
and engine PTO limitations would permit on the front end of the engine?
Then have a large cold plate in the box and draw it down as quickly as
possible keeping the engine under maximum load. It wouldn't give you the
fine temperature control of a constantly running 12 V. fridge system but
would be as good as ice. Drawing down the cold plate would be like buying
ice (and probably nearly as expensive at next year's fuel costs).

The conversion from fuel to electricity to charging and back to motive force
has got to use up more fuel than just running the compressor directly.

You might find it easier and adequately efficient to put in an
Isotherm cold plate with their smart controller that detects when the
engine is running and runs the compressor faster to suck up those amps
and freeze the plate. I put one in 3 years ago and have been very
happy with it. A big maintenance advantage is that your engine
vibration is not work hardening the copper elements of your
refrigeration.
