I would build a mini-freezer into a cool room wall at the start. The temperature controller would work.
Option two would be pump glycol on a copper tube coiled on the ceiling. Again a mini freezer could cool a glycol solution.
What temperature? 20C wouldn’t be too hard to get. I have put a carboy in a square ice chest with two liter ice jugs. Yes it sticks out but I wrapped a winter coat over the top.
