What I was getting at is that I think that there is a rhyme/reason
to avoid cooling the combustion chamber. An ammonia fridge
is a thermodynamic engine - a heat pump - driven by heat
input which boils the ammonia to start the condensation/
evaporation cycle which moves heat from the source (fridge
evap coils) to the sink (condensation coils).
If you reduce the heat input, you will boil less ammonia and
thus reduce efficiency. I think you want to cool the condenser
coils and allow the combustion chamber to get as hot as it was
designed to be in order to have maximum efficiency.
And yes, I don't know the order of the effect, but every little
bit helps when the ambient temperature is in the 100's.
Just ordered my 4 fan bank from allelectronics. We'll see if that
helps in the 100+ temp here. Plan to put them at the top of
the vent. Perhaps that design will suck big time!
