New HVAC Pool Design Solves Respiratory Issues

Oklahoma High School pool’s IAQ has been graded the highest of nearly any pool in the United States at a recent Speedo Championship meet, thanks to a combination of its HVAC system and a Paddock Evacuator System that eliminates chloramines that cause Lifeguard Lung and other respiratory problems, claims Seresco. We bring you the case study.


Even in perfect environments of proper ventilation, temperature and relative humidity, chlorine molecules attach to ammonia and other organics introduced by swimmers, resulting in a heavy, noxious gas that congregates at the pool’s water surface, causing respiratory irritations. Natatorium (a building housing a swimming pool) ventilation design strategies typically direct supply air towards the perimeter and down to breathing zones at the deck surface, but very little on the pool surface.

Seresco Technologies, which specialises in indoor pool and IAQ dehumidification, used a new combination of HVAC and exhausting chloramines from the pool surface, which now promises to be the future solution for Lifeguard Lung – a respiratory disease endemic among lifeguards – and other respiratory ailments, which plague swimmers at many of the nation’s indoor pool facilities. The new $19 million Oklahoma High School natatorium has earned appreciation for its Indoor Air Quality (IAQ) with its innovative HVAC design.
