When we consider climatizing swimming pools, spas, or wellness centers, our starting and ending points must be energy efficiency, environmental sustainability, and architectural and industrial integration. All while ensuring compliance with regulatory and user requirements.
To achieve this, we must select the most suitable equipment for the project, focusing on energy savings and reducing CO2 emissions. To meet this challenge, we should ask ourselves: What is the real demand? What solutions are available? Which equipment or solution is best suited for my project?
Borealis offers a wide range of solutions to meet these goals.
Climatizing swimming pools: What is the real demand?
On our website, we offer an online tool for calculating dehumidification and heating needs for indoor pools according to current regulations. This tool quantifies the needs of a facility to achieve the desired thermohygrometric conditions by inputting data such as pool dimensions, room geometry, operation settings, occupancy, and climate variables. This will help us select the right equipment from the solutions Borealis offers.
Climatizing swimming pools: What solutions are available?
Borealis offers several lines for pool climatization. During design and manufacturing, our commitment to technological advancement and innovation focuses on energy efficiency and sustainability. Solutions for dehumidification and climatization of these facilities include:
1. Units with refrigeration systems
- Standard dehumidifiers with a 100% refrigeration unit with optional free cooling and static recovery (LINES HV / HS / HH).
- High-efficiency units that dehumidify using refrigeration, recovery, and outdoor air with static and refrigeration recovery (LINE HRR / HRU).
2. Units without refrigeration systems
- Dehumidifiers without refrigeration using an external cold water coil with free cooling and static recovery (LINE HRS).
3. Autonomous multifunctional units
- Autonomous multifunctional units that dehumidify with a refrigeration unit, heat air and water with a heat pump, and feature static recovery (LINE HC).
Climatizing swimming pools: What equipment or solution is best for my facility?
We should choose a solution focused on energy recovery and sustainability that can include various active and passive dehumidification systems to provide greater drying capacity with minimal energy consumption. Additionally, it should offer options for static, refrigeration, or combined recovery to minimize reliance on external heating systems, reducing both primary energy consumption and CO2 emissions.
The system selection and its suitability for the facility depend on several factors that need to be evaluated together: architectural considerations, external climate, investment and return, integration with production systems, distribution systems, and usage profile of the facility.
CLIMATIZING POOLS IN WINTER, HUMID AREAS, OR SUMMER SEASONS
In winter, when outdoor absolute humidity is low, simply introducing the outdoor air required by regulations may be sufficient to dehumidify and maintain desired humidity conditions within the facility, gradually increasing as outdoor humidity rises, until it’s no longer cost-effective.
In particularly humid areas or during summer, when outdoor absolute humidity is high, using either external or direct expansion cooling coils is necessary. This allows for relative humidity control in the pool area, especially during daytime.
The use of outdoor air as the sole dehumidifying agent is most beneficial when, after a positive cost evaluation (based on geographic conditions), the hot water production that feeds the coil is particularly efficient. Even with effective recovery, outdoor air introduction can lead to negative thermal energy most of the year.
For summer cooling, choosing units with cooling mode, cycle inversion, remote condensers, or external cold water coils is necessary. At a minimum, opt for solutions with 100% free cooling and recovery features for transitional seasons. This maximizes external conditions’ efficiency while minimizing consumption to maintain the pool area’s thermohygrometric conditions.
BOREALIS: COMPLETE SOLUTIONS FOR INDOOR POOL CLIMATIZATION
Borealis provides solutions with multifunctional units, standalone heat pumps for ventilation, dehumidification, air heating, and water heating, without requiring an additional energy source. These are ideal, for example, for telescopic covers in gardens or new spa zones in hotels where primary systems may be difficult to access.
The Borealis Technical Department, working closely with the project engineer or installer, will gather all the necessary information to assess each project’s specific factors, ensuring the selection of the appropriate system for each installation.
