Indoor Pool Ventilation Requirements

In indoor aquatic facilities optimize outdoor air to create healthy and durable pool spaces by gary lochner unison comfort technologies.

Indoor pool ventilation requirements.

Mechanical ventilation systems in swimming pools. The ventilation module is a first step towards improving air quality at indoor aquatic facilit ies and reducing associated health effects. Abstract the subject of this thesis is a good indoor climate in swimming pools. Calculation of ventilation requirements for indoor pools based on moisture evaporation.

1 increased make up air required in addition to that required in the ashrae 62 standard for indoor pools. Any dehumidification system should be carefully designed to make. The difference between the vapour pressure of the pool water the vapour pressure of the saturated air in the pool hall. Imagine yourself at your favorite swimming pool.

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. A pool facility must have the proper ventilation to vent this air outside rather than into dressing rooms bathrooms etc. 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. These conditions rarely exist and pool heat is literally being thrown out the window hence waste ventilation gets its name.

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. Ventilation is also used to prevent temperature. Cibse guidance currently states 10 l s per m total floor area based on a public pool 25 x 13m. Take a deep breath.

Requirements for the volume of outdoor air level of comfort and the size of the budget. Indoor aquatic facilities design guide ventilation and air distribution. If you are outside that s a breath of fresh air. The ventilation module contains requirements for new or modified construction that include.

Proper ventilation is another important part of this indoor pool maintenance guide. 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. If an indoor facility uses chlorine chloramines can be released into the air. 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.

In medium large pools private pools or hotels the choice will be between a condense dehumidifier and a ventilation dehumidifier depending on several factors.
