Sizing of all dehumidification systems is based on the basic following information. It is important to understand the geographics and demographics for your design  temperatures/conditions. Warmer climates will have a greater cooling load, especially if bringing in large amount of Outside Air. Colder climates will have a higher heating load. It is also important to understand the building materials required for maximum protection and prevention of condensation.

The following information is needed to properly engineer your system:

• Type of facility (commercial, residential, school, medical facility)
• Size of room in square feet
• Size of pool(s) and size of spa in square feet
• Design conditions: Air, pool and/or spa temperature to be maintained
• Type of construction: 2x4, 2x6, concrete block, steel framed, manufactured enclosure, etc.
• The amount of glass (windows, skylights, door walls) within the structure
• Sensible calculations (heat loss/heat gain)
• Will a pool cover be used?

Veri-Dry will cover many of these pertinent building areas with each customer:

1. Insulation- R/Value of the building materials and insulation
2. Sensible Calculations
3. Acceptable Materials used for interior finishes
4. Vapor Barriers and why they are required
5. Skylights
6. Recessed Top Hat/Can Lighting
7. Negative Pressure
8. Outside Air Requirements if applicable
9. Windows & Skylights must be addressed
10. Air delivery system-Duct work
11. Air turnovers required
12. Temperature settings (water and air) and how they affect your operation and costs
13. Humidity settings
14. Pool Covers (best way to cut costs)
15. Chlorine & pH balance, problems with automated chemical feeders
16. Mechanical Space Required

If this is an existing facility or retrofit please call us for more information, please call us for our Retrofit Questionnaire.

Pool Room environments should be designed and maintained as a separate environment from the rest of the commercial or residential structure. Because pool rooms operate at a much high integrity level than non-pool related environments, certain precautions should be taken at the planning and designing stages. Humidity and chlorine can cause serious problems for areas (i.e. commercial -- work-out/fitness areas with equipment, residential – living areas) that are not related to pool room and are not protected by dehumidification, vapor barriers, etc.

Indoor pools are treated much the same way you would treat your home. Pool rooms require year round conditioning to prevent condensation, mold, mildew, rot, warping and an overall deterioration of the structure. With new construction, the type of building materials used, the amount and type of glass, insulation, heat gain/heat loss, windows, pool covers, will be taken into consideration when designing the system. The air delivery system will also play a critical role in the overall protection, operation and energy costs associated with indoor pools. The complete environmental control package is a SEPARATE system from office or home systems.

The Design Guidelines are in PDF format, are printable and can be shared with all involved in your project. This information has been gathered over the years from a variety of resources, building professionals, pool contractors, architects-engineers, mechanical contractors, ASHRAE, ACCA, and is not expressly the opinion of Veri-Dry. Providing of these guidelines does not negate your own research into building materials and preventive measures for your indoor pools; they are provided as an additional resource to ongoing research.
