Thanks for the suggestion. Would the evaporator coil on the inside have a signiture similar to the condenser coil. I always thought the evap coils were perpendicular to the condenser coils. Not being an HVAC guy I don't know about all these details. As usual, the devil is in them.
We've got one at work for high temperature thermal imaging. I have been improving on my insulation of the house when I thought, this might work with the brewing project. and sure enough, the condenser coils are plane as day. As Catt22 states, I've got to look into these other coils that I wasn't even thinking about. I just wanted to draw off the extra supply from the freezer to keep lager temps in the 50F range for this coming summer. A lot of folks like my American Lager but i have been limited to doing them during the warmer seasons with out compromising my serving brew.
Thanks again Catt22 for your input.
