Hey guys, I was looking for some advice. The original plan was to buy a nice new glycol chiller. But unfortunately, that portion of the budget just got swallowed up by a bathroom remodel as well as a new fire exit door. So, we are looking into building our own.
Some information. We have a used 37k btu compressor unit that came with the brewery. It was used to directly cool 4 ancient fementers which are more or less being retired. The walk in cooler we bought already has it's compressor, so we don't really have a use for this 37K compressor. Our idea is to put it outside, pipe in the freon inside to a reservoir, and have that run through an AC evaporator. Then pump glycol through that. Essentially, like any other glycol chiller you see out there, just a bit spread out. So, some questions.
Does anyone have a recommendations for the reservoir. I'm trying to keep it as small as possible while still allowing room for the evaporator to fit inside. I'm also planning on wrapping it up as much as possible with insulation.
Does anyone have a recommendation for an evaporator. I've seen a bunch of them available on Ebay for a reasonable price, but I wanted to make sure submerging them in glycol isn't going to be a problem with them.
I'm also looking for the pump to circulate through the system. I was looking at 4320K46 Extended-Life Type 316 Stainless Steel Centrifugal Pump from McMaster-Carr. Link Is this a good option, or is there a cheaper alternative out there.
And lastly, I have to ask it. Am I crazy to try to put this together?
Thanks guys. I wish I have the 9k+ to toss into a chiller, but it's not possible right now. And I want to get use out of this compressor we already have.
