Modeling the microclimate of sports facilities
Unique buildings with very special atmospheres
Sports facilities generally belong to the class of unique buildings. Without the involvement of airflow modeling methods in the analysis and evaluation of design solutions for heating and cooling systems, there is no guarantee that comfort and technological requirements will be met throughout the building volume.
Various phenomena influence the climatic parameters of these areas
In large-volume rooms, free convection flows begin to exert a noticeable effect on the propagation of diffusion air veins.
In large rooms, temperature stratification can be very important.
Sports facilities are complicated by complex phenomena such as evaporation from the water surface in swimming pools, sublimation on ice in ice rinks, and scenic effects in the most prestigious events.
Sports facilities are characterized by the presence of significant heat emission from spectators, lighting equipment, etc.
For sports facilities, there are different zones with different values for microclimate parameters: spectator zone and sports zone.
CFD modeling for swimming pools and aquatic centers
Study of trichloramine diffusion
When designing pools, various design parameters need to be considered, such as air temperature, relative humidity, water temperature and water surface, as well as air velocity, all of which affect the evaporation rate of pool water.
On the other hand, chlorine is widely used in swimming pools for its disinfecting qualities. However, it can present certain dangers when it comes into contact with organic materials. Chloramines are made by combining a chlorinated disinfectant with sweat, cosmetics and swimmers’ urine. This chemical reaction causes the development of chloramines in the air, chemical compounds that can cause respiratory, skin and eye irritation. People who work near pools, such as lifeguards, are more likely to have problems with their respiratory tra ct than ordinary people.
The quality of the calculation results depends on the input data and in particular on the quality of the physicochemical emission laws. In reality, the emission law is dynamic and can depend on the temperature and the ambient hygrometry. Different levels of modeling complexity are thus possible, the first level being to use constant laws to integrate the pollutant diffusion. It is then possible to compare different ventilation systems and to identify the areas impacted by the over concentration of pollutants.
CFD modeling for sports facilities
A design, verification and sizing tool.
The modeling of air flows is carried out using three-dimensional mathematical modeling methods (CFD approach). CFD allows the analysis and evaluation of air distribution design solutions. The conformity of the parameters of the microclimate maintained in the premises of the installation is verified according to the calculated values of temperature, velocity, humidity.
Identification, where applicable, of a zone with deviating average and local values for temperature, concentration of harmful substances, humidity, speed in the plant premises.
If we identify areas with microclimate parameters different from those defined by the design teams in charge of the project, we are able to propose adjustments and original design solutions to resolve these issues.
