How to Control Moisture and Humidity for Indoor Pools

Routine maintenance for indoor pools is a task that should not be overlooked. Indoor pools require special monitoring due to the constant need for humidity control.

Quality inspections for humidity are required to prevent potentially damaging problems from arising for these pools. Here are the essential items to keep in mind to help you maintain moisture and humidity for indoor pools.

Why Humidity Control Is Important for Indoor Pools

Humidity control is essential for the following reasons:

It ensures the stability of the pool and building

Rust that forms from humidity can damage structural elements of natatoriums and be very expensive to repair. Water vapor can also seep into electrical equipment and cause malfunctions to occur. Identifying areas of high humidity can prevent damages from developing.

It can keep the wood intact

The increased amount of humid air may also contribute to the growth of wood rot and mold. Humidity control is essential in keeping the wooden components of natatoriums intact.

It reduce the overall costs of your indoor pool

By controlling room humidity and air temperature, dehumidifier stabilizes the surroundings of the indoor pool. This results in the decreased use of outside air and the energy used to heat or cool the air.

Be Cautious with Chlorine

Indoor pools produce water vapor that is packed with chlorine. Chlorine itself is an aggressive substance. When chlorine is added to the water of an indoor pool, it not only targets bacteria and other minerals, but also severely attacks building materials when present in condensation, causing corrosion to metal and other structural damages within the building and pool. Swimming pool dehumidification is an effective way to remove the chlorine vapor from the air, and protect the building interior from causing a bad indoor environment that may result in bad experiences at the pool.

Proper Humidity Control

To better understand the processes  behind dehumidification, you need to think of the air as a mixture of water vapor and dry air – a mixture known as “humid air”. When air is warmed, it expands and holds more water vapor, while for the opposite occurrence, air contracts and holds less water vapor.  Most modern dehumidifiers run similarly to full HVAC machines, capable of heating and cooling the air and using compressor heat recovery to heat the water.

A good rule to follow to get the most from modern dehumidifiers is to maintain a two-degree difference between air (higher) and water (lower) temperatures and maintain a 50- to 60 percent relative humidity (RH). For example, a common indoor pool setup is 84°F  in air temperature, 82°F water temperature and a 60 percent RH. If the air temperature is decreased by even two degrees, overall humidity increased by roughly 35 percent, which could exceed the dehumidifier capacity.

Dehumidifier compressors run at least 10 minutes at a time, while the air blowers within dehumidifiers generally run 24/7 to offset pool evaporation. You’ll need to do monthly or bi-monthly air-filter replacements to keep your dehumidifier up and running. If you notice any unusual sounds or issues coming from your dehumidifier, notify your service contractor immediately.

Conclusion

Humidity control in swimming pool areas can save a pool owner both  time and money. Controlling moisture around indoor pools can help protect the pool environment from potential health hazards.
