Indoor Swimming Pool De-humidification / Environmental Control or Air Handling as it is sometimes called is required on all Indoor pools to prevent condensation and mold forming in the environment. Due to the laws of physics enclosed air with a water source nearby has a high relative humidity. Many pool builders believe incorrectly that you can just open a few windows or doors to ventilate the room, in practice all you are doing is letting out heat to prevent evaporation and wasting the energy in cooling the pool hall down.
Principles of Environmental Control & Air Handing
The underlying principal of air handling it to maintain a water temperature within 1 degree of the air temperature and thus prevent the water evaporating. We also apply hot air to cold surface such as glass to prevent condensation forming. In nature we call this a due point, as you get on a sunny morning with a cold ground temperature.
Environmental control in Practice
As you can see form the diagram above there is a constantly circulating system of air that is constantly being dried before being re-introduced across cold surface such as large areas of glass. On most air handing systems there is a secondary system that passes the pool water through to equalize the temperature as seen in the diagram. This systems remove excess moisture from the atmosphere in the pool hall, recapture lost heat from the pool water itself, and then recycle the heat in a warm dry condition to keep the pool room comfortable for everyone in there.
Wall Mount Dehumidifiers
This system will add either one or two small wall mounted units on the wall of the pool hall floor either low down or high up. They are also available with supplementary air heating coils to allow it to be connected up to your central heating system and heat the pool room. This system is ideal for small swimming pools and hot tubs.
Single Discharge – De-humidification with Pool & Air Heating
This system is ideal for small indoor domestic swimming pools. This system provides de-humidification, air and pool water heating and can be concealed in an adjoining room, utilising a special flexible duct and grill kit for simple installation.
Ducted Environmental Control System
Ideal for all indoor swimming pool environments. This packaged unit providing a effective heat recovery and complete heating of air and pool water to prevent condensation throughout the pools . Air distribution is normally done via ducting either infloor / overhead or in the walls. environmental control for pool quote (download)
We have been designing and installing air handing systems for many years and have built up a host of partner suppliers to design a system for your pool room. Every system is custom designed to fit the needs of the customer, the pool and the architect. Please contact us for more information or download our specifiers form and email off to us.
