HVAC Dehumidification Indoor Pools
Controlling Humidity in Natatoriums/Indoor Pools
How to get the PERFECT BALANCE of Water and Air from Building to Dehumidification
Much information has been distributed over the years regarding indoor pools, for “how” and “why” to properly control the humidity in an indoor pool. Questions arise as to what works and at what cost – from exhaust fans, exchanging outside air for indoor air (waste ventilation), opening windows, plug in basement style dehumidifiers, 100% Outside Air systems, to mechanical refrigeration based dehumidification systems. A pool room is like a pot of boiling water on a stove… the moist warm air coming off the pool in the form of evaporation rises and stratifies in the ceiling areas and walls of the pool room. Left uncontrolled, this 100% humidity eventually destroys all building materials and equipment, ceilings cave in, mold, rot, mildew occur.
Today’s heat recovery refrigeration based dehumidification systems reduce this humidity to the recommended ASHRAE Guidelines of 50-60%, maintains temperatures, provides heating and cooling, and adds resource of free “reheat” to room and pool while in operation. In many cases, dehumidification is an afterthought or after moisture problems become apparent. In some cases equipment not appropriate to these types of structures is installed and in ashort time becomes apparent that it does not work to control the environment. Costs of preventing deterioration problems with pool rooms can be prevented in the design stage and are much less than the costs of repairs down the road. What we see today is a …
