CFD validation by measurement of specialized ventilation equipments on duct tract

This article describes measurement of HVAC distribution box on air duct track in Laboratory of Environmental Engineering (LEE). Firstly, the paper describes the LEE and then measurement apparatus with description of calculation methods. Then follows specification of sample with introduction to newly developed equipment for positioning of the anemometer. The evaluation of results of measurements with CFD comparison follows. The article is concluded with discussion over measured data with an outline for further research
