Due to an automotive incident that tapped into my project savings, I had to put plans on standby for this month, but hope to get rolling in March. So far this is my basic floor plan:
I am trying to work out a way to run this off of one AC unit since its a smallish area that will have the tar insulated out of it. The AC will be in the "fridge" area. What I am trying to figure out is how to cool without opening up a ton of air circulation that will make temps fluctuate wildly. The options I have considered are:
Bathroom fan: Something with a lowish cfm rating between the "fridge" and "fermentation room" pros- cheap and easy, wire through a relay to a household thermostat to kick on and off. cons - air flow circulation between the two rooms. To get air movement for effective cooling I will an input and a return fan and that means air leakage and a bigger AC unit to maintain steady temps. This will probably be fine for a smallish area like I am designing, but expert advice from those more familiar with HVAC applications is needed.
Liquid coolant: I know some have done this in smaller cabinets; place a tub of propylene glycol on the cold side with a submersible pump, run the lines through the wall to a radiator/fan setup for cooling. Pros: maintain an airtight cool side Cons: more moving parts, possible expense, may not achieve high enough heat transfer to maintain steady temps.
If anyone has advice or has solved this problem already, please let me know!
