The case for sports hall ventilation
Sports hall ventilation often combines the worst circumstances for trying to make a project work. Ducts are usually mounted at a high level, often over 10m, and supply air temperatures tend to be quite a bit warmer than the ambient room temperature, leading to wide ∆t and fairly buoyant air, which needs to travel long distances due to the mounting height. Added to these issues is the lack of air volume for the size of the room. This is typically one (1) air change or less and often requires velocity control – especially if badminton is played in the courts area. We can address all these issues with our bespoke fabric ducting.
Benefits of using Prihoda Fabric ducts for Sports Hall Ventilation
Why fabric ducting not traditional ducting?
At Prihoda, we’ve done many sports hall applications, so we know what works and what doesn’t. Our fabric ducts are a lot lighter than traditional rigid ducts and much easier to install at high level – much safer for the installation team too, with it being lighter. It also requires less secondary steelwork. Fabric ducting doesn’t dent either; important for sports halls where footballs and the like often find themselves up amongst the ducting!
Bespoke systems for your desired air pattern
Looking at the supply air ∆t, the distance of travel, and the system external static pressure, we can accurately model the travel distance and velocity of the air pattern designed. We can then adjust, as necessary, the size and regularity of nozzles and/or the system pressure or air temperature difference required to achieve air movement within the occupied zone. It’s the graphic velocity and distance modelling that allows us to make bespoke systems with the knowledge that they’ll perform exactly as designed, and to pass that information and confidence on to our customers.
Introduce airflow at gentle velocities
In terms of design and getting the air down, we employ a mixture of diffuser types to achieve the most appropriate air pattern. We use large fabric nozzles to create induction across the middle of a sports hall. The nozzles move lots of air and induce air at a high level into the air pattern, encouraging movement from below. Along the side of the sports hall, we throw the air into the occupied zones at the sides of the courts along the walls – introducing air at gentle velocities where people are usually standing or resting. We never blow the air directly into the court if badminton is played in the court areas.
