 |  "AC too cold"
, posted Fri 23 Jun 20:59  
In my office we have a 10 ton unit AC which makes the air way too cold. The tech guy gave me a long-winded explanation of why he can't fix it, but somehow it seems to me it must be possible to do something.
The unit was installed in 1983. The thermostat on the wall doesn't do anything. The unit itself has an old BC thermostat which he had set at 34 degrees. I don't know if I should touch it (he's gone for the weekend).
Thanks for any advice.

is this a constance volume unit or VAV? Is this unit for just your office or others too?

What’s controlling the unit? It sure sounds like that thermostat isn’t.

I'm not sure; I wish I knew more about this stuff.
He told me the problem has something to do with humidity; because it's a big unit it cools off the entire area right away but it doesn't take the humidity out. So he said he has to turn the boiler up a little to add some heat to dry out the air. This seems very inefficient to me.

I concure...
P.S If Humidity is a problem he sould look at installing a bypass damper to bypass some air when the return humidity is above 60%. With 60% return, load shouldn't be a problem when the air is reduced accross the coil.
