Indoor pools create one of the most demanding HVAC environments in a building. Water constantly evaporates into the air, while Southern Ontario winters create a large temperature difference between warm pool rooms and cold exterior surfaces. Without proper humidity control, the result can be condensation, corrosion, uncomfortable air and damage to the building.
What humidity should an indoor pool maintain?
The correct setpoint depends on pool-water temperature, room-air temperature, building construction and equipment design. Rather than chasing a single number, operators should maintain the conditions specified for their natatorium and dehumidification system and investigate persistent condensation or discomfort.
Warning signs to watch for
- Condensation on windows, doors or exterior walls
- Rust or corrosion on metal surfaces
- Musty odours or visible moisture damage
- A room that feels excessively humid
- A dehumidifier that runs continuously or struggles to maintain setpoint
Why Ontario winters matter
Cold outdoor temperatures make interior surface temperatures especially important. Warm, moisture-laden pool air can reach its dew point on cold glazing, frames and wall assemblies. A properly operating dehumidification and air-distribution system helps manage moisture while supplying conditioned air where it is needed.
Maintenance is part of humidity control
Filters, coils, drains, sensors, fans, refrigeration components and controls all influence system performance. Commercial facilities and residential pool owners should have equipment inspected on a preventative schedule and address changes in humidity performance early.
King Air specializes in indoor-pool dehumidification systems for commercial and residential facilities throughout Southern Ontario. If your pool room has condensation, humidity or equipment-performance concerns, professional diagnosis can identify the cause before moisture creates a larger building problem.
