So we are pulling 2500 gallons a day and cooling half the time at say 150 tons with 500kW?
Something like that. I can't say exactly how much water you will be pulling down because all our fan coil units are hooked up to a drain, so I never measure it. As for how much you are cooling with the lights off, I can't say I can give you a concrete number on that either. The thermostats turn the chillers and the fan coils on and off when need be.

All I do it size it for worse case scenario and then add redundancy to cover any failures.

Ligjts go off, heat load drops and cooling isn't required. Maybe need heat. How do you get dehu without cooling?

the heat strips on the air handlers. and at this point they are acting just like dehumidifiers. They will put a bit of heat off maybe but no more than a standard portable if sized correctly.

correct mr. blah?

A portable dehu will put off 25% more heat. We size the heaters to the size of the fan coils so it do not raise or lower the temperature of the room when the dehumidification is occuring.

lol. You didn't make my life miserable. Retarded installers that don't read the directions make my life miserable.
