The dehumidification of indoor or covered pools is an absolute technical necessity that goes far beyond the simple comfort of swimmers. Owning a swimming pool at home or in a professional establishment is a luxury that comes with a major climatic challenge: the constant evaporation of water. Without a robust control system, this water vapor turns into aggressive condensation, capable of destroying frameworks, promoting mold, and peeling off coatings in record time. At Climatik, we design specific air treatment solutions to transform your pool hall into a healthy, durable, and pleasant environment.

Why is pool dehumidification vital?

When a body of water is heated (generally between 26°C and 30°C), it naturally evaporates into the ambient air. In an enclosed space, the air quickly reaches its saturation point. If this humidity is not mechanically extracted, it tries to escape through the coldest surfaces (windows, walls, ceilings), creating the phenomenon of condensation.

The consequences of poor management:

• Structural degradation: Humidity combined with chlorine fumes attacks concrete, rusts metal reinforcements, and rots woodwork.

• Health problems: Excessively humid air promotes the proliferation of dust mites and fungi, which can cause respiratory problems for occupants.

• Thermal discomfort: The sensation of dampness and the persistent smell of chlorine make the swimming experience unpleasant, even stifling.

1. How does a pool dehumidifier work?

To ensure effective pool dehumidification, refrigeration cycle devices (dedicated heat pumps) are generally used.

The operating principle

The device draws humid air from the pool hall. This air passes over a cold evaporator where water vapor condenses and is then discharged into the wastewater. The now dry air then passes over a hot condenser where it is reheated before being reinjected into the room.

• The energy bonus: The heat recovered during water condensation is used to reheat the blown air. Some high-end models at Climatik even allow this heat to be reinjected directly into the pool water to save on heating costs.

2. Different pool dehumidification solutions

The choice of equipment depends on your pool's configuration and the desired aesthetic.

Ambient consoles

This is the simplest solution for existing pools or controlled budgets. The device is placed on the floor or fixed to the wall directly in the pool hall.

• Advantages: Quick installation, attractive price.

• Usage: Small to medium-sized pools.

Recessed dehumidifiers (through-the-wall)

Only the intake and discharge grilles are visible in the hall. The machine is installed in an adjacent technical room.

• Advantages: Space-saving, sleek aesthetics, and reduced noise level.

• Usage: High-end renovation or new construction.

Ducted systems (Air Handling Units)

This is the ultimate solution for invisible and ultra-efficient pool dehumidification. The unit is placed in a technical room and the air is distributed via a network of ducts, with diffusers strategically positioned along the glass walls.

• Advantages: Total acoustic comfort, optimal protection of windows against fogging.

• Usage: Large indoor pools, professional spas, and aquatic centers.

Calculating the evaporation rate

To properly size your Climatik installation, our experts rely on calculating the mass of water evaporated per hour. The reference formula takes into account the pool surface area (S), the vapor pressure difference between water and air, and the activity in the pool.

A simplified formula used in the industry is:

W = S x C x (Pw - Pa)

Where:

• W is the amount of evaporated water (kg/h).

• C is the activity coefficient (higher if you have water features or active swimmers).

• Pw and Pa are the saturated vapor pressures of water and air.

The Climatik objective: Maintain relative humidity between 55% and 65%. Below this, evaporation accelerates (costly); above this, condensation appears.

3. The keys to a successful installation

Successful pool dehumidification requires adhering to a few golden rules:

1. The 2°C rule: To limit evaporation, the air temperature must always be 2°C higher than the water temperature (e.g., water at 26°C, air at 28°C).

2. Window sweeping: Dry air must be directed towards cold surfaces (bay windows) to "break" the condensation layer.

3. Using a cover: When the pool is not in use, a cover or roller shutter reduces evaporation by 80%, thus relieving the dehumidifier and reducing your energy bill.

4. Anti-corrosion treatment: The chlorinated environment is destructive. All machines offered by Climatik feature coils treated with specific coatings (epoxy or cataphoresis) to resist oxidation.

Why choose Climatik for your pool project?

The air in a swimming pool is a complex fluid. At Climatik, we don't just sell you a device; we offer comprehensive expertise in air treatment.

• Technical expertise: We perform precise thermal assessments to avoid oversizing (costly) or undersizing (ineffective).

• Acoustic comfort: We select the quietest compressor technologies on the market to preserve the tranquility of your relaxation area.

• Energy savings: Our high-efficiency heat recovery dehumidification units can halve operating costs compared to simple air extraction.

Conclusion

Pool dehumidification is the most important investment after the construction of the pool itself. It guarantees that your real estate investment does not degrade over the years and that every swim remains a moment of pure pleasure, without fog or unpleasant odors.
