Ventilation of the pool hall
Ventilation systems in swimming pool rooms are slightly different from those used in living spaces, as they have three functions: they provide air exchange, reduce humidity and remove unpleasant odours. This makes it possible to create a comfortable environment for people relaxing in the pool and also prevents the formation of condensation, which affects the condition of walls, equipment, etc.
Although, according to standards, the permissible humidity in swimming pool rooms is 65%, but Kliwenta specialists recommend maintaining optimal parameters – 45-50%. This will avoid the formation of condensation and the microclimate will be more comfortable.
Kliwenta engineers pay attention to all the nuances when designing a ventilation system, for example, at what speed moisture will evaporate. In other words, it is necessary to clearly know the temperature of the water, because the warmer it is, the greater the evaporation will be and, accordingly, a more efficient ventilation system should be chosen.
Excessive humidity not only affects people’s well-being – they find it difficult to breathe and move around. Moisture adversely affects the materials of the room, corrodes metal and damages finishes. When humidity levels reach 80 per cent, condensation runs down the walls, unpleasant odours develop and mould and mildew begin to grow. It is therefore very important to think properly about the ventilation system in the pool hall.
Kliwenta specialists recommend observing the following parameters:
- Optimum water temperature – 25°C;
- Air temperature – 27°C;
- Indoor pressure is 5% lower than outdoor pressure.
It is important to consider that the ventilation system of the pool hall must be separate. In other words, it must not be dependent on the ventilation system of the whole building.
Good ventilation makes it possible to provide the necessary air exchange, to dry windows and walls and to prevent condensation. In such rooms, heated air with low humidity is blown along the windows from bottom to top. However, this method is not always suitable, due to the individual characteristics of the rooms. For this reason, it is advisable to seek professional advice to select a suitable ventilation system.
How to organise ventilation in a pool hall
What is the best way to organise a ventilation system in a pool hall? There are various systems that help to exchange air in this type of room. Do not rely solely on natural ventilation. The best option is a mechanical supply and extract system. This can be a single unit or consist of a separate supply and extract system. Depending on how the air entering the room is heated, systems can be electric, water or heat recovery.
In most contemporary detached houses and bungalows, the heating appliance used is a gas boiler. In this case, it would be advisable to connect the air handling unit to it. The water supply is regulated by an automatic feed unit directly from the boiler to the water heater. This makes it possible to maintain the set temperature parameters in the building at the outlet of the ventilation grilles directly into the room. Such water systems are currently quite popular.
It takes a lot of energy and finances to install a ventilation system for a pool room. In addition, the process is quite lengthy.
To save money, you can install a supply and extract unit with heat recovery. Such ventilation systems are quite popular in flats, private houses and holiday homes. The principle of the system is quite simple: air coming in from the street is heated directly by the air that is removed from the room.
If there is a need to reduce the running costs of the ventilation equipment, it is possible to install a supply and extract unit with a plate heat recuperator.
Each pool room requires an individual approach to the design of the ventilation system. Kliwenta’s specialists are ready to carry out any project, regardless of its complexity. Our many years of experience allow us to solve all problems related to the installation, design and maintenance of air conditioning equipment.
Dehumidifiers
You can recognise the principle of a dehumidifier even from its name. But as well as significantly reducing the humidity in a room, it also offers the possibility of reducing energy consumption. Therefore, it automatically reduces the efficiency of the ventilation system. Kliwenta specialists recommend that customers only install high-quality units. This makes it possible not to spend extra money on installing a powerful radiator as well as ventilation. In this case, it will be possible to comply with operating parameters such as 1 m³/h of air per 1 m² of water surface.
Practice shows that some of the most popular dehumidifiers are Danvex or Dantherm. The principle of their operation is as follows: the air is condensed inside the dehumidifier housing, then discharged through a drainage system into the sewer system or, after thorough cleaning, returned to the pool. These dehumidifiers can also filter the air. However, this does not mean that you can do without a ventilation system, as any appliance, including a dehumidifier, generates heat.
Kliwenta specialists advise on combining a supply and exhaust ventilation system with a dehumidifier. In order for engineers to start designing the ventilation system, they need the following data:
- Structure and thickness of the pool walls;
- Room size;
- Data on the size of swimming pool mirrors;
- Information on air heating capacity;
- Individual customer preferences for air and water temperature;
- Room plan showing where the customer would like the equipment installed.
When you contact Kliwenta, they will help you choose the best equipment to ventilate your pool hall and dehumidify the air in it.
