Pool Natatorium Dehumidification

“In the last 10 to 15 years research has shown that poor air quality in indoor swimming pools has a negative impact on the health of swimmers, coaches and pool workers. Poor indoor pool air quality, caused by compounds off-gassing from pool water, has been linked to eye, nose and throat irritation, exacerbation of asthma symptoms, as well as to a predisposition to develop bronchial hyperactivity and asthma. These health concerns are in addition to the well-known damaging effects of the indoor pool atmosphere on pool buildings and equipment.” - Designing for IAQ In Natatoriums - by Randy Baxter - ASHRAE Journal, April 2012

Indoor aquatic facilities are also energy-intensive spaces. Pool water and surrounding air temperatures must be comfortable for swimmers. The high humidity of these spaces requires continuous dehumidification; and the presence of toxic chloramines, which are pool water disinfectant byproducts, necessitates thorough air replenishment.

The XeteX design approach is to manage the natatorium’s ventilation requirement and humidity control by delivering high levels of fresh Outside Air which results in a healthier, more comfortable pool environment. The hot, humid and gas-filled air is exhausted and cooler, generally less humid air is brought in to meet the fresh air requirements of the space. XeteX uses a flat-plate heat exchanger to pre-condition the incoming fresh air, and when needed further apply heating or cooling to meet the Supply Air requirements. By taking this approach, the natatorium will have overall better IAQ and lower operational costs than a standard mechanical dehumidification pool system.
