Indoor Pool Design, Consultant and Construction - Aquatic Designs, International: Air Quality

Air Quality Indoor Pools

Many factors are involved when designing indoor pools, the most important being the air quality, humidity and controlling the transmission of water vapor into other parts of the structure.

Air Quality

Our consulting mechanical engineer has 4 decades of international experience designing indoor pools and aquatic facilities.  He will perform complicated calculations to determine the proper levels of the following items:
 
Air turns - the turn over rate of the volume of air within the enclosure.
Dehumidification -  extracting moisture from the air to control condensation.
Water Temperature - proper water temperature to minimize evaporation
Air Temperature - proper air temperature to minimize condensation
Vapor Barrier - a lining to prevent moisture transmission through walls and surfaces
Positive Air Pressure - air pressure designed to prevent vapor from exiting the enclosure or transmitting into adjacent areas
Heat Recovery - heat that would be vented to the outdoors is recovered and placed back into the pool water, saving energy

Controlling condensation is not merely a matter of matching the pool temperature to the air temperature.  It is a complex set of many variables.  The slightest change in one, affects the others.

Dehumidifiers are mandatory.  Do not think that you are going to come up with a creative method of avoiding the costly installation of a dehumidifier.  What ever hair brained idea you have, has been tried before - and FAILED!

Vapor Transmission

Failing to control the humidity in the enclosure will result in condensation on the walls, glass and inside the walls.  Vapor within the walls will result in black mold, wet drywall, corroded electrical wiring and components, rusting light fixtures, dry rot, bacteria growth and a myriad of other related biologicals.

Proper placement of air registers and returns is also paramount.  Our engineer's computer model will simulate the air flow within the enclosure and allows for the precise placement of these components.
