Indoor swimming pools are a nice addition to any home, hotel or apartment complex. However, as relaxing as it may be to have access to a heated indoor pool, they require a delicate balance in order to prevent moisture build up from developing and damaging the surrounding area.
The high humidity which is usually present in an indoor pool environment can result in more than water running down interior windows. That moisture can destroy the building structure with rot, create health problems with mold and mildew and create an uncomfortable environment.
The aspects that affect the moisture levels inside the average indoor pool include:
1. The Building Envelope
The ‘structure’ or ‘room’ that contains the pool is a key component. The way in which it is constructed will have a huge impact on the environment of the pool.
Construction materials, the use of a vapor barrier, windows and foundation can all play a part in the lifespan of the indoor pool.
2. The Ventilation
As indoor pools create high humidity levels, being able to move the moist air out and away from the pool area is important. Air supply ducting and venting should operate in such a way that windows do not collect condensation. The air quality also impacts the pool users.
There are automatic humidity control solutions available that can activate air ventilation and extraction systems depending on the amount of humidity in the air. For more information on automatic humidity control systems, click here.
3. The Dehumidification
For effective control of humidity in the air inside the indoor pool room a dehumidifier is often required. A properly functioning dehumidifier unit would be able to keep the relative humidity at a level between 50 and 60 percent. Heating and cooling of the air can also assist with this process.
The Problem With Evaporation
Think of the indoor pool and the room it is in as a large sealed box. Water that gets splashed out of the pool from swimming, horseplay and even through wave action created by swimmers can end up on the tile surface outside of the pool. In addition to this, the heat in the room causes it to evaporate.
A surprisingly large amount of water can evaporate from a large indoor swimming pool during the course of an average day. This water vapor has to go somewhere and without the proper elements in place it adds to the humidity in the sealed box. This humidity can become dangerous.
High humidity creates problems in any setting but when it is in an indoor swimming pool, the dangers are greater. Mold, rot and corrosion develop over time. These things will eat away at the pool structure, the building structure and create air quality issues that are bad for human health.
When chlorine is added to the mix, the resulting damage can take place even faster as chlorine is an aggressive chemical. When chlorine condensates it can eat away at any kind of building material ranging from walls and ceilings to the tile decks and even the pool itself.
With dehumidification measures in place, and functioning properly, the moisture content in the air is kept at a safe level. With correct humidity levels in an indoor pool building, it creates a safe environment for the structure and good air quality for those enjoying the pool facility.
Keep Your Indoor Pool Safe From Damage
Because indoor pools are costly to maintain and operate, it is important to keep them functioning properly. The best way to do this is to ensure that the building that houses the pool is built correctly. And you need to keep the building neat and clean, using these house cleaning tips. The building materials should be able to withstand the higher humidity levels.
Vapor barriers must be present to protect the building structure beyond the walls. Ventilation should be in place to provide a correct and ongoing exchange of warm and cool air. The warm humid air should be removed with cooler outdoor air filtering back into the pool building.
A dehumidification system should also be included in any indoor swimming pool setting. This will control the amount of moisture present in the air reducing the risk of condensation.
Controlling the moisture levels in an indoor pool area can be tricky, but needs to be addressed to protect your property from expensive damage. By staying on top of excessive moisture in your indoor pool area, you will be able to enjoy it year-round.
