swimming pool ventilation for dehumidification without Air Conditioniong or desiccants.
swimming pool ventilation for dehumidification without Air Conditioniong or desiccants.
(OP)
I am trying to quantify an air change rate to provide heat and humidity relief in a pool area. See photo. It is strictly used in the late spring - summer - early fall when ambient is reasonable. Chicago area. There is no air conditioning at all. Gets very hot and humid. Windows are operable and there are some wind turbine ventilators in the roof. There is also a small exhaust fan on the far wall.
I am thinking of installing intake louvers on the far wall and exhaust on the near wall (not in the photo) to sweep the whole room. I am trying to quantify what would be appropriate. This is a low-budget project. 7,500 CFM gives me 4 air changes per hour. Was going to put the fan on a VFD for operator control.
Any ideas?

If you can figure out how to control humidity by simply ventilating the area, please contact me. We will go into business together and put those bums at Carrier, Trane and Lennox out of business.

Chicago has pretty high wb in all seasons but winter.

What temperature is"reasonable" ambient. What is RH or WB and DB temp
What is "very hot and humid"?
What temp is swimming pool water?
Is there any low cost source of cold water? that is at least 5C lower than ambient air temp?
Only then can you start to work out if your scheme helps. At the least I would put three or four blowers along the roof and louvres along the wall to generate an air flow. 4 acph seems low for such an environment. If you want to alter
humidity then you'll need a source of cold fluid. Normally this is via a chiller. Evaporative coolers don't work well at high WB temps or high humidity levels.Good luck

Also: If you get a response it's polite to respond to it.

Maybe look at some kind of desiccant wheel without cooling? Space seems to be at a premium, so I don't know where you would put this. With enough airflow, the room would have any added water from the pool removed, and maybe the wheel would reduce the amount of humidity from the outside air. I've never done or looked into this, so no idea if this will even work, but it may be an option.
