Chillers and Humidity

I live in the dirty south, and by dirty I mean sticky and humid. I also live in an older house, before air conditioning. This place was never made to hold anything in or keep anything out, quite the opposite is true. My house has high ceilings, lots of windows, an attic fan, and the insulation of a Styrofoam cup.

In order to keep the humidity bearable inside, that means blasting air over cooled coils. I feel like I am loosing this battle. If I want it to be not sticky in here, I've got to keep the a/c in the low 70's. Now, I'm a Texan and low 70's is a little chilly for me and being that cool in the summer time seems a little ______ to me.

Now that we've toured my knee, onto the elbow. Are my aquariums fighting against me? I know their loosing water from topping them off. I also know that some of my a/c is fighting to keep their temps from getting enough to boil fishies.

Are chillers the answer, or would that make more humidity problems worse? from an old summer job, I know that indoor pools keep the ambient temperature one degree higher than the water temperature to keep from causing condensation. I don't remember it feeling dry in any way though.

Anybody have any words of wisdom?

I guess to put it more simply-

How much humidity do you think tanks add?

Do chillers help with humidity or just temp?

All your evaporation as you know adds to the humidity. The chiller should reduce evaporation but it will also add a considerable amount of heat to the surrounding area. You could feel the heat wave when you walked into the living room when my reef was set up with a chiller.

Oh, you're asking if the tanks are adding to the humidity in the house. I'd say a little but a chiller wouldn't do much in that respect. Maybe have a hood or glass cover for the tank? The moisture can go back into the tank and not in your house.

ps.. evaporation happens more in the winter because the air is less humid.

Toss some glass tops on top of the tank

One thing you can do to avoid heat from your chiller is to place it outside, as close to your aquarium as possible. Then place a igloo style dog house to protect it from weather over the chiller. This is something we have done a number of times for large tanks with chillers. It will require longer plumbing lines. But noise and heat are all outside

if its already very humid in there the evaporaion should slow down. air can only hold on to so much water.

and yeah evaporation definately happens when its cold. water will even evaporate out of ice. there are companies that treat water damaged documents and books like that (its an expensive process so usually only very important things). its called sublimation. you can freeze the paper before it gets moldy and evaporate the moisture out of it and completely restore it

Thanks a lot. I guess it makes sense that the tanks are not really adding too much to the humidity. I did end up buying a humidifier during the winter, so I guess the tanks can't be adding that much.

I spent a few minutes looking at chillers. The fact that the heat would be removed from the tank and then put back in the room makes them a little less appealing. Putting the unit outside makes more sense, but in my case it would probably end up under the tank anyway. Plus they look expensive.

I guess I will look for other ways to cut back on the humidity.

Thanks,

air conditioners and dehumidifiers are the only way to do it. even if its not insulated great it will still keep the humidity down a little. and even if its not really making the room a lot cooler, the lower humidity will make it feel a little better.

my uncle lives in arizona. he comes up here to mass when the weather is over a hundred and he complains about that its worse here when its 80 and humid

I recently moved into an apartment and the window units are too big. As a result, the compressors don't come on often enough and it is either muggy or freezing. I think I was just witch hunting.

thanks again

I would get a dehumidifier to go with the ac unit. They really do wonders. They add some heat to the room, but would keep the air much dryer. Get one that you can run a hose to either a floor drain or outside.

Should allow you to keep it more to your liking.
