Challenge

St Neots Table Tennis Club wanted to install a new ventilation and heating system in the playing area to improve air circulation and maintain comfortable temperatures throughout the colder seasons.

The Club asked Prihoda UK to design fabric diffusers that would connect to fan units supplied by Stax Associates and distribute the air through the playing hall.

The 25m-long hall is a large open space containing a range of table tennis tables and related equipment.

The pitched roof with exposed rafters meant there was a risk that the heated air would rise and pool at the highest point. This risk needed to be considered at the design stage.

Additionally, keeping draughts away from the playing area was very important, as air currents can interfere with table tennis games.

Solution

Prihoda’s solution is a tailor-made round fabric duct installed centrally across the length of the table tennis hall.

The duct is attached to the exposed rafters, avoiding the lighting supports located directly below.

Two rows of 30mm fabric nozzles, sonic-welded onto the duct, deliver the conditioned air into the hall. The nozzles are set up at an angle to spread the air out and cover the entire hall without creating air currents in the middle of the hall.

Why nozzles and not laser-cut perforations?

Because they give plenty of throw to the supply air, ensuring it reaches the occupied zone even when it’s warm and buoyant. And with the duct mounted at the highest point, the hotter air can’t pool just below roof level, creating a much more efficient air distribution.

Result

With the new fabric duct in place, St Neots Tennis Club can offer a much more comfortable environment for members, staff and visitors.

It’s easier to control air temperatures thanks to the efficient air distribution created with the fabric nozzles.

The conditioned air reaches the occupied zone without interfering with the table tennis games or causing noticeable air currents and draught.

The fabric duct looks sporty and aesthetic in this modern dark grey non-permeable textile material with tensioners to keep the duct nice and taut all the way through.

Players can now enjoy a more pleasant environment where they can hone their skills and have fun.
