Refrigerator cooling fans

[Gregory OConnor]

I dont think the advantage is cool air over the coil as much as it
is removing hot air from the compartment. heat is a necessary part
of Einstines amonia evaporation process and it is important to
maintain a gradual cooling. I put a fan ducted to blow in the
compartmet but others (I think Ryan or Scott) have a fan at the
exhaust which would also remove the chance that blowing in will
pressurizing the compartment and push un burned lpg into the bus.
