Dehumidification in swimming pools

A high degree of water evaporation in indoor pools, especially in combination with the high ambient temperatures, leads to enormous humidities and an unpleasant feeling of being oppressively hot. For those using the swimming pool, these climatic conditions not only impair personal well-being, but also pose a serious risk to the health of visitors and swimming pool staff in the form of circulation problems. The damp air provides germs and bacteria with the perfect breeding ground. Given the bathing guests’ light clothing, these can very quickly get into contact with human skin and, in the worst case, cause infections or diseases.

Alongside the potential health hazards, warm humid air also has an impact on the fabric of the building. In so-called “cold spots” in particular, such as glass surfaces, metallic components, or external walls, the evaporated water condenses and can lead to the formation of mold and corrosion over longer periods. The resulting damage leads to shorter maintenance and repair cycles of the building’s infrastructure, entailing unplanned interruptions of operation and therefore, and above all, higher costs. Operators of swimming pools should therefore insist on a contemporary dehumidification system being installed.

Energy-efficient technology from Condair

One traditional method of dehumidification that is still commonplace today is a simple ventilation and circulation system, whereby the damp air is sucked in via a ventilator and drier air streams in from outside.

This external air must then be reheated, which takes a huge amount of energy. This method is therefore incredibly wasteful. Considerably more energy-efficient is the humidity control offered by air dehumidification systems specially for use in swimming pools.

These are based on a closed coolant circuit, which makes the operation up to 60 percent more economic than conventional systems that work with input and output air. To recover energy, all Condair swimming pool air dehumidifiers work using the heat pump principle. This results in significant savings in operating costs, as the heat recovered in the heat pump circuit is fed back into the room’s heating.
