The Benefits of Indoor Pool Room Dehumidification

Residential swimming pool dehumidifersAn indoor pool, whether it’s at home or a hotel, spa, or gym, can be one of life’s greatest pleasures or your worst nightmare depending on how well you control the room’s humidity. Children and adults alike love to splash in the water and enjoy the security, comfort, and convenience of an indoor setting any time of the year. However, an indoor pool also comes with its share of challenges and responsibilities for the owner or operator, and one of those is ensuring proper pool water chemistry while maintaining a clean and inviting atmosphere.

How to Extend the Life of Your Pool Room Dehumidifier

The pool room dehumidifier is the most crucial piece of HVAC equipment for protecting the integrity of the pool room structure from mold, mildew and corrosion.  It controls the relative humidity, room heating and cooling, and can also maintain the correct pool water temperature when equipped. Assuming that the correct capacity dehumidification system was selected initially, many long years of service can be expected as long as the owner adheres to a proper maintenance schedule.

Why You Shouldn’t Adjust a Pool Room Thermostat

Monitoring and managing indoor humidity levels can be challenging in any type of space, but indoor pool rooms present unique difficulties. Without careful attention and management, imbalanced room air temperature and pool water temperature relationships in these rooms can cause corrosion, condensation, mold, mildew and poor air quality affecting swimmers comfort and building integrity.

In commercial indoor pool rooms, trained employees are typically on hand to manage dehumidification processes, temperature monitoring, and pool water chemistry. However, residential pool rooms usually can’t rely on employees for upkeep, nor can most semi-commercial spaces in hotels and condos; service technicians are available, but their vists are usually infrequent. 

Partnering with knowledgeable HVAC professionals — ones that can provide useful feedback, recommend reliable technology, and suggest customized management plans for monitoring and controlling humidity levels — can allow for significant time and cost savings.

Pool Room Dehumidification Basics

To properly manage an ideal indoor pool space, structured dehumidification standards are essential to follow. One of the most important standards is to maintain pool room air temperature 2 to 4 degrees warmer than that of the pool water temperature.  This relationship allows minimal pool water evaporation into the air of the pool room. Having the pool room air temperature cooler than the water temperature encourages pool water evaporation into the air causing dehumidification systems to run longer than needed.

It may seem practical to alter a system’s dehumidifier set points during daily pool use, but this can be highly disruptive and not recommended.  Normally pool water temperature set points are constant and by extension the room air temperature will be constant as well.   Below are three common situations illustrating this.

  • In an attempt to save on energy and operating costs, some pool managers will cover a pool and then lower the room temperature during the time the pool is closed. This practice is not recommended but can be done if needed. Before the pool cover is retracted the room air temperature must be brought up to 2 – 4 degrees warmer than the pool water temperature or an instant fog will be released, covering the windows of the room with condensation.
  • When large groups of people gather in the pool room for a party or an event, the room temperature rises naturally and the guests may find the room air temperature uncomfortable. If the dehumidifier set point is dropped to accommodate the guests, the dehumidification system may not be able to keep up with the rising room air temperature and moisture output from the imbalance.
  • Pool managers looking for a way to accommodate a diverse swimming audience may want to quickly heat up or cool down the pool water by adjusting the temperature of the thermostat or the water heating source. However, this can quickly double the room’s moisture load, making it impossible for even an oversized dehumidifier to keep up.
