    Coolbot cooler vents into tap room - too noisy!

    Well this definitely belongs in the “Stupid Stuff” category...

    Built our serving cooler with the Coolbot-operated AC venting into the taproom. Got everything finished and hooked up and turned on the AC only to discover that IT’S REALLY FREAKING LOUD!!! Like WAY more noisy than I want our cozy little chill taproom to have to endure (yeah I know - what did you expect dumba$$?)

    Does anybody have any ideas on how to attenuate the noise? There is enough space that I could probably build a small room around it but I’d love to find a less involved / obtrusive solution if possible. Has anybody else dealt with this sort of problem?

    Just curious what AC unit you had used?

    airconditionercanada had ComfortAire models which we've used successfully. smaller units for fermenter temp rooms and the biggest 115V unit we could get for an 8 by 10 3C cold room. We've even managed to keep a 6 by 10 trailer cold at festivals using the smaller units but they will freeze up. Yes, they will all be noisy.

    As for the original poster, why not switch to a mini-split type ac unit and get the condenser placed in a better location (like outside).

    It’s an LG 15K BTU window unit.

    can you or anyone with one of these venting indoors tell me how much heat and humidity they produce? our local inspector wont give us the green light now that we built it even though he was previously ok with it because he thinks the ac unit on the cooler in our basement will create too much heat and humidity? I believe they turn humidity into the form of condensation but dont create it myself... the basement area is about 700 sq ft and the cooler is 9x10x6h and we have the lg 24,500btu unit.

    Condensation occurs at the evaporator--the cold side. The condensate is removed from the air, so it actually dehumidifies the cooled space. You should have a catchtray and drain for the condensate so it isn't a problem. On the hot side, there is no condensate and no way it can contribute to humidity. It will throw a lot of heat, and will be noisy.

    Yes thats was my understanding on how an ac unit works as well. Do you know of any "code" we would be breaking? As far as I understand its just like running a large glycol chiller or fridge indoors?

    Part of the issue is our local inspectors basically told me they just skeptical that a 24,000btu air conditioner is powerful enough to bring the temps down in that small cooler. I have explained many other breweries in nearby cities are using them and brought in coolbot documentation and am waiting on them at this point. Its extremely frustrating as now that its built they have changed their minds.

    With that size cooler with 5" foam insulation sealed with greatstuff and caulk on all the walls at 38 degrees will the ac unit be running enough to make the basement very hot? its freezing down there 3/4 of the year due to a crawlspace behind the poorly sealed back wall which we could add some sort of vent system to try to cool it through but otherwise there will be no easy way to vent the ac unit directly.
