How much 'gain' would we get if we sunk a 55 gallon barrel into the

running?

Any evaporated water would be made up with condensate.

Hi,

Would be safer and need less pressure/power to just trickle it over
the condenser.

You won't get much evaporative cooling if the ambient humidity is very
high though.

Worth keeping a close eye on the ali fins for any galvanic corrosion
reaction with the copper pipes.

If the compressor gets really hot it might help to have a fan blowing
on it.

cheers,
Pete.
