Indoor Pool Ventilation Requirements

Mechanical ventilation systems in swimming pools.

Indoor pool ventilation requirements.

Imagine yourself at your favorite swimming pool. Ventilation requirements for indoor pools healthy and durable indoor pool environments require a well designed ventila tion system with effective air distribution and sufficient outdoor and exhaust air to remove toxic and corrosive chloramines from the space. If an indoor facility uses chlorine chloramines can be released into the air. The air changing rate should be between 4 6 per hour according to the air distribution principle.

It s very important to achieve good indoor climate in swimming pool in order to swimmers and spectators don t have bad effect on their health. The difference between the vapour pressure of the pool water the vapour pressure of the saturated air in the pool hall. Indoor aquatic facilities design guide ventilation and air distribution. Abstract the subject of this thesis is a good indoor climate in swimming pools.

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. Cibse guidance currently states 10 l s per m total floor area based on a public pool 25 x 13m. Any dehumidification system should be carefully designed to make. Calculation of ventilation requirements for indoor pools based on moisture evaporation.

In indoor aquatic facilities optimize outdoor air to create healthy and durable pool spaces by gary lochner unison comfort technologies. In general it may be said that a mechanical ventilation rate of 1 ach one air change per hour of the pool enclosure will be sufficient to maintain reasonable relative humidity levels when a pool cover is used regularly. In medium large pools private pools or hotels the choice will be between a condense dehumidifier and a ventilation dehumidifier depending on several factors. A key question for system designers becomes how much outdoor air is required.

A pool facility must have the proper ventilation to vent this air outside rather than into dressing rooms bathrooms etc. 1 increased make up air required in addition to that required in the ashrae 62 standard for indoor pools. The ventilation module is a first step towards improving air quality at indoor aquatic facilit ies and reducing associated health effects. 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.

The ventilation module contains requirements for new or modified construction that include. Proper ventilation is another important part of this indoor pool maintenance guide. Ventilation is also used to prevent temperature. If you are outside that s a breath of fresh air.

The air quality of indoor pool environments has come under heavy scrutiny in recent years.
