Specific benefits of dehumidifiers for new swimming pools

        In new indoor swimming pool projects, dehumidifiers are not only optional equipment, but also a core facility to ensure the safety, comfort and long-term stability of the pool environment. Below are six specific benefits of dehumidifiers for new swimming pools, covering a wide range of dimensions including environmental control, health protection and cost savings:

‌1. Precise control of indoor humidity, avoiding structural corrosion and mold‌

• ‌Humidity standard: Indoor pool air humidity needs to be controlled at 50%-60% (per ASHRAE standards) or water vapor evaporation will cause long-term moisture damage to walls, ceilings, metal components, etc.
• ‌Protection of building materials: High humidity environments are prone to carbonization of concrete, rusting of steel, and warping of wood. Dehumidifiers maintain humidity within safe limits through condensation dehumidification or rotor dehumidification technology, extending the life of the building.
• ‌Prevents condensation: When indoor air dew point temperatures are higher than building surface temperatures, condensation can adhere to glass and walls, creating a slip risk and mold growth. Dehumidifiers eliminate this potential hazard.
• 

‌2. Improving air quality and swimming comfort‌

• ‌Suppression of harmful substances: Pool sanitizers (e.g. chlorine) react with organic materials to produce irritating gases such as trichloramine, the volatilization of which is exacerbated by a high humidity environment. Dehumidifiers reduce the concentration of harmful gases by lowering humidity to avoid eye and respiratory discomfort for swimmers.
• ‌Equilibrium body temperature: When the humidity drops below 60%, the body's heat dissipation through sweat evaporation becomes more efficient, and swimmers can still feel comfortable even if the water temperature is low (e.g., 26°C in a competition pool).

‌3. Reducing energy consumption and operating costs‌

• ‌Heat recovery function: Modern pool dehumidifiers (brands such as Dantherm, Calorex, etc.) have a built-in heat pump system that recovers the latent heat of evaporated water vapor during the dehumidification process and uses it for pool water or air heating, resulting in energy savings of up to 701 TP3T.
• ‌Reduction of air-conditioning load: High humidity will increase the burden of air conditioning refrigeration, dehumidifiers can reduce the operating frequency of air conditioning systems by independently controlling humidity, and the comprehensive energy saving effect is remarkable.

‌4. Extension of equipment life‌

• ‌Protection of electrical equipment: High humidity levels can easily lead to short circuiting or corrosion of pool lighting systems, automation control cabinets and other electrical equipment. Dehumidifiers maintain a dry environment and reduce equipment failure rates.
• ‌Maintenance of ventilation systems: When humidity levels are too high, ventilation ducts are prone to condensation buildup, which breeds biofilm and corrodes ducts. Dehumidifiers reduce such problems through humidity control.

‌5. Compliance with health and safety regulations‌

• ‌International normative requirementsFor example, the United Kingdom's Pool Water Treatment and Air Quality Guidelines (PWTAG) and the United States' Public Swimming Pool Health Code specify that indoor swimming pools need to be equipped with dehumidification systems to prevent airborne diseases.
• ‌Anti-slip safety: Reducing humidity reduces the risk of slippery floors and complies with occupational safety standards (e.g., OSHA).

‌6. Enhancing user experience and business value‌

• ‌Customer Satisfaction: A dry and comfortable environment extends the length of stay of visitors and enhances the competitiveness of high-end pools (e.g., hotels, clubhouses).
• ‌Reduced maintenance frequency: Moisture control reduces maintenance such as wall cleaning and mold removal, reducing long-term operating costs.

‌Selection and Installation Recommendations‌

• ‌calculated load: Based on parameters such as pool surface area, water temperature, ventilation, etc., through the formula Q=A×(Pw-Pa)×FQ=A×(Pw​-Pa​)×F($Q$is the dehumidifying capacity.$A$is the surface area of the water.PwPw​together withPaPa​being the partial pressure of water vapor at the water surface and in the air.$F$(for the evaporation coefficient) for accurate selection.
• ‌system integration: Dehumidifiers need to be linked with fresh air systems and air conditioners to avoid heat loss due to over-ventilation.
• ‌mounting position: Prefer concealed installations (e.g. in plant rooms or suspended ceilings) to minimize noise disturbances and to ensure that the return airflow covers the water surface area of the pool.

concluding remarks‌

         For new swimming pools, dehumidifiers are not only "comfort equipment", but also a core investment to ensure building safety, reduce operation and maintenance costs, and increase business value. Through scientific selection and system integration, its effectiveness can be maximized, laying the foundation for the long-term success of swimming pool projects.
