At indoor swimming pools, water evaporates because of ambient conditions, pool surface area and pool activities. As a result, bacteria that form in the environment threaten human health and the structure is damaged due to high humidity. Therefore, humidity control at indoor swimming pools where intensive humidity occurs is highly important for facility users in terms of necessary hygienic conditions, human health and lifetime of building.

Why Humidity Occurs in Indoor Swimming Pool Areas?

If partial pressure of water vapor of ambient air is below saturation temperature then evaporation occurs on surface of pool water. Ambient air temperature and relative humidity, pool water temperature, ambient air movements and pool usage type affects evaporation.
