Why should I use a dehumidifier instead of an air-to-heat exchanger or a ventilation system to control my indoor pool room humidity?
The purchase price of a dehumidification system may be higher than heat recovery ventilators, but they have similar operating costs and do a better job of controlling the pool room environment. Air-to-air heat recovery ventilation requires the incoming air to be heated in the winter and cooled in the summer. Ventilation and air-to-air heat exchangers can provide some control of indoor humidity levels during those periods of the year when outdoor air is drier or less humid than indoor air (typically during the winter months). The indoor humidity is not really “controlled,” but rather floats to a level determined by the actual outdoor conditions at the time. This can be a reasonable design for an “indoor/outdoor” pool in a mild climate, where the doors and windows of the pool area are opened to the outdoors during the warmer months as needed during good weather or as conditions require. However, in most homes or hotels or anywhere where the pool will be enclosed year round, the ventilati
