Why Dehumidifiers Are Needed in Indoor Pool Environments


Dehumidification systems are key to implementing integrated designs for indoor swimming pools, aquatic centers and natatoriums. In addition to working in harmony with systems that control water temperature, water quality and air quality, Desert Aire safeguards the health of building users; protects the structural integrity of building systems; and conserves energy, water and water treatment resources.


The heating, cooling, and moisture loads of a natatorium are a product of seasonal variations in outdoor air temperature and humidity, solar gains and losses, as well as the presence of spectators and bleacher areas. As the equipment centerpiece of natatorium HVAC systems, the dehumidifier controls humidity in pool enclosures to counter what is created by evaporation, regardless of outdoor conditions. Humidity control also protects building structural elements, furnishings, and support systems such as lighting.


The ASHRAE recommended relative humidity in a natatorium is to stay between 50% and 60%. Lower relative humidity increases operation costs due to increased evaporation and can lead to swimmer discomfort due to evaporative cooling from their bodies when exiting the pool. Higher relative humidity increases the risk to the building structure.


The overarching goal in managing heating, cooling and moisture loads is sustainability: ensuring the natatorium can continue to fulfill the purposes for which it was built in a safe and cost-effective manner. We offer a multitude of dehumidifier systems that meet this goal and excel in various sizes and environments.
