Today, the handball team of Skjern has optimum conditions at their new home ground, Skjern Bank Arena. A brand new multipurpose arena with a large and enthusiastic crowd and a good air distribution. Together with a KE-DireJet® fabric ductwork system, the CO2-controlled ventilation ensures that the temperature is kept at 22°C even during a hectic semi final between Skjern and FCK (Copenhagen).
In co-operation with Bravida Esbjerg, KE Fibertec AS has supplied the fabric ductwork system to Skjern Bank Arena which opened in 2005. The initial operational experiences were very positive, and the manager of Skjern Cultural Centre has stated that: The solution with fabric ductwork works very well and has proven to be an effective solution. We have experienced a good indoor air quality in the arena, and there are no draughts and no problems with the air temperature.
The supplied solution is a KE-DireJet® fabric ductwork system with nozzles in a non-permeable material that combines irectional injection through nozzles with a long penetration (the ability to inject hot air from the ceiling and to the floor). The total air volume is 40,000 m3/h which can be VAV-adjusted to reach the basic ventilation of 13,640 m3/h. The air volume is adjusted by means of a CO2-device with a maximum value of 1500 ppm. With many spectators in the arena, the CO2-value will increase and the air volume will gradually go from basic ventilation to maximum ventilation by adding more KE-DireJet® fabric ductwork system.
It is an energyfriendly control that ensures a constant optimum indoor climate and since the fabric ductwork system is also very effective there will be no heat accumulation below the ceiling.
In co-operation with the technical staff at Skjern Cultural Centre, KE Fibertec carried out temperature measurements during a semi-final match in the men's handball league between Skjern and FCK.
The first measurements were carried out approx. ½ hour before the match started at 4 o'clock p.m., and the temperature was measured 2 metres above the floor and right below the ceiling and in the duct to determine if the temperature efficiency is optimum even at full capacity. Measurements show that there is no considerable temperature gradient (max. 1,4°C) between floor and ceiling, and at no time did the temperature in the occupied zone exceed 21°C. We may conclude that if anyone is at the boiling point during a home match with Skjern Handball team, it can not be blamed on the indoor climate!
