I have a 400L all-fridge upright fridge that I use for fermenting.
It has enough room for two fermenters one above the other.
I also have a heat source (100W light bulb at the bottom) and the cooling coils are at the top. Both are thermostat controlled.
I can get the top half of the fridge to +-1 C of any temperature from 1 - 28C or so. Nice
The problem is that the top of the fridge is a different temperature to the bottom of the fridge, and I would like a relatively uniform temperature.
The situation has gotten worse since I replaced the wiremesh shelf in the middle with a plywood reinforced shelf so I could do 60L brews
So, I'm thinking of putting 1 or 2 cpu fans in the fridge to circulate the air
Has anyone got any experience doing this? Or can suggest where to put the fan or fans?
I'm thinking of making two holes on the back left/right of the middle solid shelf to circulate the air. Possibly putting one 3" or so fan blowing up, and another blowing down. I figure this will create a circular air movement, hopefully moving the cold/hot air around to make the fridge more uniform.
The thermostat sensors are currently in the top half of the fridge.
I guess I would use a phone charger of some sort to power the fans?
I know there is plenty of advice for chest freezer + collar conversion for keg fridges, but what about uniform temperatures in an upright fermentation fridge?
Any thoughts appreciated
Thanks.
