Thank you Sir for your reply.
I've explained myself poorly. The two fans available for this problem are both 12 volt. I had an empty 7.5 amp breaker on the panel so will run a wire over to the galley
for this fan (either the 2.1W--4" fan or the .30A--3" fan) ... I'll put a switch upstream of the fan to use only when I am running the reefer.
For the past year I have run the refer between 10 and 20% of the time. I'm hoping that if I can keep the coils cooler the energy costs for the refrigerator
will decrease and I'll feel comfortable using it more. The 12 volt muffin fans I have -- I can place either (which would you use?) at the hose (exits outside the boat 8" away / no sharp bends) and angle the fan to blow (or suck) directly (12") at the motor
This makes sense to me but to you?????????
Which direction for the air flow?
I know the ideal now (via Grainger) but would prefer to use what I have available and the direction of air flow has my stumped. The hose that goes from outside the boat (vent) to the reefer cabinet is 2.5" in diameter and that hole (in cabinet) is approximately 3" from the bottom -- at the level of the motor/coils.
Thank you for your attention thus far.
Aside: Basically, the only time I turn on my inverter
is to power the refrigerator. Essentially the boat is entirely powered via 12 volts. I've looked at your site (wow!!!) and eventually would like to upgrade to a 12 volt refrigeration
system however the budget
won't allow that as of yet. Maybe in a couple years.................!
