Why are suspended ceilings not recommended?
They create an unconditioned space that is prone to condensation and corrosion problems. Pools with suspended ceilings are notorious for corroded hardware (‘T’ bars and hangers) and condensation soaked tiles falling into the pool.
Why are skylights not recommended?
They are prone to condensation problems in colder weather. The quantity of supply air (3-5 CFM per ft2 or 15-25 l/s per m2 of glass) required for condensation control must be sufficient to blanket the entire skylight. Visible ductwork is required to supply this air to the skylight and can cause concerns about aesthetics with the owner.
How important is duct layout?
It is absolutely vital. The total quantity of supply air must be sufficient to provide four to eight air changes per hour (as recommended by ASHRAE) to prevent stagnation and air stratification. Care must be taken to ensure the entire space receives the required amount of air flow and to prevent supply air from short-circuiting to the return inlet.
Can a DRY-O-TRON® be used to heat a whirlpool?
The economics of this option make it a good investment, but only for larger whirlpools. A suitable whirlpool is one that represents more than 25 percent of the total evaporation from all pools.
What special design concerns must be addressed?
A pool that will host swim meets has essentially two modes of operation: normal and swim meets. A swim meet generally has a very large spectator load while the pool swimmer density is less than during normal operations. The Activity Factor for a swim meet should be 0.65 whereas in normal operation it would be 0.8-1.0, (as per the “Activity Factor” table on page 17). The designer should review computer models of each mode to ensure that the size of the selected unit is appropriate for both.
