A Review from the Perspectives of Corrosion, Maintenance, and Efficiency
Chemicals used in indoor swimming pools—especially chlorine-based disinfectants—not only affect water quality but also the indoor air and the lifespan of HVAC systems. Therefore, chemical load must be considered when designing pool HVAC systems.
Process of Chemicals Evaporating into the Air
Volatile chemicals such as chlorine and bromine evaporate from the water surface into the air in indoor pool environments. Insufficient ventilation or improper system selection can lead to the accumulation of these chemicals in the air, causing damage to system components.
Corrosion Risk and Material Selection
Chemical vapors cause corrosion, particularly on metal surfaces. Components such as heat exchangers, fans, duct interiors, and electrostatic filters are directly affected. Therefore, it is recommended to use stainless steel or epoxy-coated materials in pool HVAC units.
Filtration and Fresh Air Rate
To control chemical concentration, high-efficiency filtration (HEPA, activated carbon filters) and adequate fresh air supply are necessary. Additionally, proper pressure balance is critical for both user health and system efficiency.
Energy Consumption and Maintenance Needs
Chemicals like chlorine can reduce filter lifespan and increase energy consumption. Regular maintenance and filter replacement in pool HVAC systems extend system life and improve energy efficiency.
Conclusion and Recommendations
The effects of pool chemicals on HVAC systems cannot be ignored. From project design onwards, selecting the right system, using appropriate materials, and planning regular maintenance ensure user comfort and system durability.
