Choosing a Replacement Indoor Pool Dehumidifier: Key Factors and Features

by
Indoor pool dehumidification

Every indoor pool facility is different, requiring its own specialized system to meet the needs of its guests. But even the best dehumidification system will eventually go beyond its useful life and require replacement.

Maybe you have a system that works and you want to maintain that while making modern upgrades. Maybe you’re unhappy with your indoor pool dehumidification system and you’re looking to find something better.

Whatever led you to pursuing a replacement dehumidifier, we’re here to help you find the perfect solution for you. When purchasing a replacement indoor pool dehumidifier, there are several factors and features to keep in mind so you get the right option for your needs.

Key Considerations when Choosing a Replacement Indoor Pool Dehumidifier

Pool Size and Humidity Load

Calculate the volume of the pool room, including the height of the ceiling, to determine the overall air volume that needs dehumidifying. You’ll also need to account for the evaporation rate of the water in the pool. This helps determine how powerful the dehumidification system needs to be. The larger the pool surface, the higher the evaporation rate, leading to increased humidity.

Higher water and air temperatures increase evaporation rates. Frequent pool use also raises humidity levels.

Dehumidification Capacity

Measured in pints per day (ppd), this indicates how much moisture the unit can remove from the air. A dehumidifier should be capable of handling the maximum expected humidity load. Calculate this by considering the evaporation rate from the pool and any additional sources of moisture. For larger indoor pools, commercial-grade units with higher ppd ratings may be necessary.

Airflow rate, measured in cubic feet per minute (CFM), represents the amount of air passing through a single point in one minute. CFM is another important measurement when considering ventilation needs. A higher airflow rate ensures faster moisture removal and more efficient air circulation.

Installation Requirements

Make sure the dehumidifier unit you’re looking at fits in the available space. Some systems are designed specifically for indoor or outdoor use, for example. Before you buy, triple-check that your system will fit in the space you have available.

Proper ventilation is also key for the dehumidifier to function efficiently. Will additional vents and ductwork be required for your desired unit? If so, then that work should be factored into the unit’s cost – which may make it the wrong choice for your needs.

Maintenance and Durability

Choose a dehumidifier with easy access for maintenance and parts that are easy to replace. Units with features like washable air filters and accessible drainage systems simplify upkeep. The primary way to prevent ongoing service costs is to ensure the unit is constructed from corrosion-resistant materials, given the high humidity and potential exposure to pool chemicals. Units with stainless steel or coated aluminum components resist corrosion better in humid, chlorinated environments.

Control Systems and Features

Better controls, whether through precise humidistats or other mechanisms, mean more comfortable pool environments. They also make it simpler to lower energy costs, giving you control over when the dehumidification unit runs.

A few modern indoor pool dehumidifiers also offer remote monitoring systems through apps and other tools. Seresco units feature remote control and monitoring via WebSentry, making it easier to manage pool conditions.

Operating Cost

Replacing an indoor pool dehumidifier can be costly up-front. While it’s tempting to go with the most affordable option, that may not be the best choice in the long run.  Poorly constructed units may be cheaper, but they can result in countless service visits and may need to be quickly replaced themselves. Lower capacity units tend to be more affordable, but they may not have the output needed to keep moisture from gathering in your building. That can lead to massive construction and repair costs.

Energy efficiency, durable materials, and simple installation processes can all make a dehumidification unit more expensive at the on-set. Each of these features can save you substantial money in the long term, whether by keeping the unit in good working order as it ages or simply cutting your energy costs. When it comes to replacement indoor pool dehumidifiers, an early investment in a high-quality system always pays off.

Accurately sizing your dehumidification system based on the dimensions of your indoor pool area and the rate of evaporation are critical to creating a comfortable pool environment. Factors such as pool size, water temperature, and room temperature will impact the system’s capacity requirements.

Consulting with a professional engineer can ensure that the system is appropriately sized for your specific needs – but you can get started yourself by calculating evaporation rate and measuring dimensions of the pool space. This is essential information to determine the necessary output and power of your indoor pool dehumidifier system.

Ventilation and Airflow

Air refrigeration is only one part of the dehumidification process. Proper ventilation and air exchange is essential to maintaining air quality and preventing the buildup of moisture. Good air circulation helps distribute conditioned air evenly and prevents stagnant areas where humidity can accumulate. Without adequate air circulation, your dehumidification system will struggle to clear moisture and your facility or pool room will become uncomfortable – or even unsafe.

Ensure that your pool area is designed with ventilation in mind. Your refrigeration unit and air exchange solution need to work together to keep humidity at comfortable levels.

Maintain Control over Humidity Settings

Invest in a dehumidification system that allows for precise control over humidity levels. Maintaining an optimal humidity range not only enhances comfort but also prevents issues such as condensation, mold growth, and structural damage.

Programmable controllers can be used to set and maintain specific humidity levels throughout the day. Advanced control software can make this process much easier for indoor pool operators, as well. Seresco’s WebSentry technology allows for even more precise control and support from anywhere with an internet connection.

Buy Energy-efficient Systems

Designing an energy-efficient dehumidification system will save you money and keep your pool facility eco-friendly. Even if the upfront costs are greater, consider the long-term cost-savings when purchasing a dehumidification unit. In many cases, the energy savings will outweigh those initial costs before long.

Look for systems with advanced technologies such as variable-speed compressors, heat recovery options, and fluid cooled units or dry coolers. These features can significantly improve energy efficiency without compromising performance.

Use Pool Covers and Enclosures

Pool covers and other enclosures can reduce evaporation and limit the introduction of external moisture. These measures can work in tandem with your dehumidification system, helping to maintain consistent humidity levels and lower energy consumption. This simple solution can result in less strain on your dehumidifier, saving money in energy consumption and wear.

Make a Plan for Regular Maintenance

A well-maintained dehumidification system operates more effectively and has a longer lifespan. Implement a regular maintenance schedule, including filter replacements, coil cleaning, and inspections. Timely maintenance not only ensures optimal performance but also prevents potential issues before they escalate.

Ongoing maintenance is important to consider during the initial purchasing and design process, as some systems will be easier and less costly to maintain than others. Seresco indoor pool dehumidification systems are built with maintenance in mind, with parts that are easy and affordable to replace and service.

Consider the Surrounding Spaces

Indoor pools are often part of larger facilities, such as fitness centers or hotels. Ensure that your dehumidification system accounts for the surrounding spaces, providing comfort and humidity control in adjacent areas. This holistic approach contributes to a positive overall experience for facility users.

A Guide to Choosing the Right Size Dehumidifier for Your Indoor Pool

by

Indoor pools provide a year-round oasis, but they also come with challenges, such as excess humidity. To maintain a comfortable and safe environment, investing in a dehumidifier is essential. However, selecting the right size is crucial for efficient performance. In this guide, we’ll explore the factors to consider and steps to take to ensure you choose the best size dehumidifier for your indoor pool.

What to Consider When Sizing Your Indoor Pool Dehumidifier

Calculate Pool Area

The size of the indoor pool directly influences the capacity needed for a dehumidifier. Measure the length and width of the pool room and multiply these dimensions to determine the square footage. This basic calculation serves as a starting point for choosing the appropriate dehumidifier capacity.

Consider Pool Activity

Different pool activities generate varying levels of humidity. For example, a lap pool used primarily for swimming may require a smaller dehumidifier than a pool used for water aerobics or a hot tub. Consider the frequency and intensity of pool usage to better estimate the dehumidification needs.

Account for Surrounding Spaces

Indoor pool areas are often accompanied by adjacent spaces, such as changing rooms, showers, and storage areas. These spaces contribute to the overall humidity load. Measure and calculate the square footage of these areas to ensure the dehumidifier can handle the combined moisture output.

Calculate Evaporation Rate

To measure how quickly water evaporates into your pool room’s air, measure the distance between the pool deck and the surface of the water. Then, let some days pass to allow water to evaporate as normal. Take the same measurement again in the same spot as before.

Divide the difference between the measurements by the number of days that have passed to get an approximation for inches/centimeters of water evaporated per day. Convert that to square feet or meters per day and multiply that value by the surface area of your pool. Then multiply that number by 7.48 to arrive at gallons of water evaporated each day. This measurement is essential to accurately sizing any indoor pool dehumidifier.

Factor in Pool Temperature

The temperature of the pool water affects the humidity level in the air. Warmer water temperatures result in higher humidity. Be sure to consider the desired pool temperature when selecting a dehumidifier, as it influences the unit’s capacity to effectively remove moisture.

Determine Desired Humidity Level

Understanding the ideal humidity level for an indoor pool is crucial. Most indoor pools aim for a humidity level between 50% and 60%. Choose a dehumidifier with the capacity to maintain this range to prevent issues such as condensation, mold growth, and discomfort for pool users. Other facilities may have to comply with building codes or other regulations, as well.

Consult Dehumidifier Sizing Charts

Dehumidifier manufacturers often provide sizing charts that correlate pool size, temperature, and humidity levels to the appropriate unit capacity. Consult these charts to narrow down your options and ensure a proper match between your indoor pool’s characteristics and the dehumidifier’s capabilities.

Seek Professional Advice

When in doubt, seek advice from professionals specializing in indoor pool dehumidification. They can assess your specific circumstances, recommend suitable units, and provide valuable insights into installation and maintenance requirements.
