Indoor Pool Room HVAC Design

Project Description

We designed an HVAC system for an indoor pool room or natatorium (from the Latin natare, ‘to swim,’ and torium, ‘a place for’) featuring a DXair DVA outdoor condensing unit connected to an indoor dehumidifier and downstream inline electric reheat to control humidity and maintain optimal comfort.

A 300 CFM continuous exhaust maintains negative pressure for effective moisture management, while a 1,000 CFM supply air system with a linear ceiling slot diffuser creates an air barrier along the interior of the glass walls and the Vitrocsa glass pivot door to minimize condensation. Inactive sections were integrated into the diffuser to achieve the total area required for maintaining proper air velocity and throw. This design allows the diffuser to maintain a continuous, seamless appearance by blanking off sections as needed.
