Humidity Control is Essential for Indoor Pools

Swimming Pool Humidity | Humidity in Swimming Pool | Uncomfortable Environment Around the Pool

Humidity Control is essential for Indoor Swimming Pools for a variety of factors including health, hygiene, safety, etc. Indoor swimming pools can be a great source of entertainment and is quite common in countries of the middle east. It provides a climatic relief. However, major problems arise because the humidity from these pools causes mold and mildew growth, fogginess, frequent accidents, condensation on vents, glass panels, AC grills, rotting away of wood, windows which lead to increase maintenance cost and uncomfortable humidity level for people inside.

Effects of Uncontrolled Humidity

  • The uncomfortable environment around the pool
  • The strong and persistent smell of chlorine
  • Condensation on vents/ glass panels/ AC grills
  • Corrosion of interior due to chloride-induced corrosion
  • Deterioration of windows / rotting away of wood
  • Peeling paint, deteriorating motor joints, bricks, etc.
  • Mold and mildew growth
  • Fogginess
  • Frequent accidents (slipping/ falling) caused by wet floors
  • Increased maintenance costs

While indoor pools may have some advantages over outdoor pools, there are several issues that should be addressed in order to maintain a safe environment. Most buildings are fabricated with airtight construction, which means air is not easily exchanged from the inside to the outside. This can cause humid air to get trapped in the pool area. Problems that occur due to high humidity can be lessened with the use of a high-quality dehumidifier.

Uncontrolled Humidity around Indoor Pools can Cause Irreparable Damage

Rust that forms from humidity can be damaging and very expensive to repair. Water vapor can also seep into electrical equipment and cause it to break. Indoor pools produce water vapor that is loaded with chlorine. Chlorine can cause corrosion to metal and cause structural damage within the building and pool. Swimming pool dehumidification is an effective way to remove the chlorine vapor from the air. Another problem that occurs with improper moisture control in swimming pool areas is wood rot. Dry wood will not decay without the help of moisture, so humidity control in swimming pool areas can keep the wood intact.

Humidity Control for Indoor Pools can be costly to maintain and operate. One of the main expenses is heating the pool. Since much of the heat loss from indoor pools are caused by moisture vaporizing from the pool surface, a dehumidifying system can help pool owners cut energy costs. Many pool dehumidifiers are built to follow conservation guidelines.

It is necessary to ensure that pool water temperature is cooler than air, an ideal temperature would be 80°C water temperature. Expensive air-conditioning and ventilation are not enough to mitigate these problems mentioned above.

High Indoor Pool Humidity Leads to Hygiene Issues

Swimming Pool Humidity | Humidity in Swimming Pool | Indoor Swimming PoolMoisture-rich air can also cause health problems for swimmers because humid air breeds fungus and bacteria easily. Common hazards that occur from too much humidity are mold and mildew. Mold can be carried to any surface of the pool area. Individuals may develop allergic reactions like rashes, severe coughs, and respiratory problems. Proper moisture control can greatly reduce the number of bacteria and fungi that form.

Humidity control in swimming pool areas can save a pool owner time and money. Using a high efficiency, a low-cost dehumidifier will prevent or reduce problems associated with moisture-filled air. Controlling moisture around indoor pools is an effective way to maintain the integrity of the surrounding building and safeguard swimmers from potential health hazards.

General Recommendations

The relative humidity in Indoor Swimming Pools should be maintained at 50-55 % at about 26°C during winters and 23°C during summers.
