Dehumidifiers

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.

In order to remain functional, comfortable, and safe, swimming pool areas must be equipped with high-quality, reliable dehumidification systems. As with any complex system, pool room dehumidification equipment requires regular maintenance and, periodically, replacement.

Determining whether replacement is the appropriate action, however, can be daunting or confusing, as diagnosing problems is often a complex process in itself. And once system issues have been identified, an operator must determine which course of action will best rectify them: repair, retrofit, or complete replacement.

Vertical farming is an agricultural method in which crops such as leafy greens and herbs are farmed indoors within climate-controlled environments. As the process becomes more efficient and economically viable, these urban farms are becoming more prevalent across the United States.

By controlling important environmental factors indoors, growers are able to cultivate better-quality crops at higher yields and in shorter periods of time. This also reduces the human footprint on the environment, as water and nutrients are conserved and less pollution and emissions are generated.

Whether using dehumidification for industrial, commercial, residential, or swimming pool applications, customers must determine, if applicable, which of the two typical cooling system options will be the best fit for their application — air cooled or water cooled. 

Air cooled dehumidifiers, for indoor pool room dehumidification and other projects, are the most common type and deliver warm dry air back to the space when operating. When room cooling is needed they are coupled with an optional outdoor remote condenser. This allows them to deliver warm dry air or cool dry air depending on what the controls call for.

Humidity is a major concern for all indoor swimming pool owners. Air-to-air heat exchangers and ventilation systems were commonly used to control pool room humidity.

These methods are expensive to operate and wasteful, in that they constantly exhaust previously heated or cooled air outdoors. They also often fail to prevent structural damage caused by excess moisture, as the formation of mold and mildew in cold walls can cause irreparable damage.

The most effective way to control pool room humidity is to use a full dehumidification system that serves to remove destructive moisture and add room heating as a by-product of the dehumidification cycle.

Hotel, motel, and residential indoor pool rooms are just a few scenarios where you can find dehumidification systems controlling the relative humidity. An unexpected failure of a dehumidification system in these facilities can have some considerable negative impacts.

A malfunctioning dehumidification system can cause mold and mildew build up quickly. This can lead to musty smells and poor air quality, not to mention structural issues.

Malfunctioning dehumidification systems can also lead to unhappy customers and bad reviews, which could hurt a business. In an industrial setting, a manufacturer can lose a large amount of money in downtime, missed deadlines, or ruined product when relative humidity is out of control.
