Indoor Swimming Pool Ventilation

Indoor pool ventilation the air quality of indoor pool environments has come under heavy scrutiny in recent years.

Indoor swimming pool ventilation.

A minimum of two air changes per hour shall be provided for indoor pool areas. When humidity goes to high and a building has cold surfaces or air leaks to outside it causes numerous problems. A pool facility must have the proper ventilation to vent this air outside rather than into dressing rooms bathrooms etc. This can rot a building from the inside out and can also affect indoor air quality.

Basically an indoor swimming pool can be dehumidified in two ways. An indoor swimming pool continuously produces large quantities of chlorine or salt laden water vapour through the process of pool water evaporation. Bathhouses mechanical equipment rooms storage areas and indoor swimming pool enclosures shall be ventilated either by natural or mechanical means. Ventilation is also used to prevent temperature stratification in facilities with high ceilings.

A ventilation system can only provide effective humidity control for an indoor pool when the outdoor air is reasonably dryer or the same as the indoor air with a lower relative humidity 365 days per year. Indoor aquatic facilities design guide for a pool environment to be healthy and durable chloramines must be removed by a well designed ventilation system that has proper air distribution and enough circulating outdoor air to exhaust chloramines from the space. A typical indoor pool space has. Wellness areas saunas hot tubs dressing rooms rest rooms restaurants etc.

In these cases a condense dehumidifier is often chosen because it is simple to use and the investment is small. These conditions rarely exist and pool heat is literally being thrown out the window hence waste ventilation gets its name. Are all part of the swimming pool air conditioning and should not escape our minds. In small pools and spas there is rarely a need for large volumes of outdoor air.

Room ventilation shall prevent direct drafts on swimmers and shall minimize condensation. Ideally the humidity level should be maintained at 50 to 60 percent either by exchanging humid air for fresh drier air or by installing a dehumidification system. If an indoor facility uses chlorine chloramines can be released into the air. Without ventilation an indoor swimming pool will be constantly dripping in condensation which leads to very poor indoor air quality and essentially an unoccupiable room.

Our expertise and passion for ventilation has now lead us winning many projects involving indoor swimming pool ventilation and dehumidification which is a very refined product which needs to be designed and installed correctly to avoid damage to buildings and assets by way of consequential damage from condensation and high humidity.
