Typical applications include YMCAs, municipalities, athletic, recreational and fitness centers. Large natatorium pools like those used for swimming competition can have a surface area of 10,000 square feet and larger. Waterparks are a newer pool category and are distinguished by their even larger spaces and high water activity.
The evaporation rate is generally high due to the large pool surface area, elevated water temperature and bather activity. Air and water temperatures along with humidity are especially difficult to balance, and improper control usually results in an uncomfortable environment compounded by structural damage due to the corrosive chloramine-laden environment.
Natatoriums require a large, high capacity dehumidification to control condensate formation from pool water evaporation. They require ventilation to meet safe building requirements, and the addition of colder outside air can increase heating costs during winter months or increase cooling/dehumidification costs during hot summer months.
Dehumidification systems for natatoriums need to be cost effective in heating both the pool water and air space. Operational costs are important due to the high cost of energy to heat and cool the facility, and performance and reliability are equally important to maximize return on investment and user satisfaction.
PoolPak® offers dehumidification equipment using both mechanical refrigeration and outside air. Mechanical refrigeration recycles the heat captured during dehumidification to heat the air or water while the outside air system effectively captures heat from the exhaust air stream.
