Report For Signalisten by David Villarroel November 15, 2007 Laboratory Test Results of the Ventilation ducts Introduction Signalisten, a social housing corporation in northern Stockholm, approached Tetex Konsulter AB and KTH for a ventilation retrofit project concerning air quality within their apartments. Signalisten’s apartments will need to meet future government regulations in indoor radon emission levels together with low energy use. To accomplish this task, a new ventilation duct system was proposed to increase air flow into the apartments. The apartments would be fitted with a new duct system for supplied air to each of the rooms. Purpose As suggested by the introduction, the new duct system is to be tested before any installation occurs in the apartments. Signalisten would like the duct design to meet appropriate pressure drops and air flow requirements, therefore an experiment conducted over a configuration of ducts was proposed. The experiment is located in KTH’s Energi Tillämpad Termodynamik (ETT) laboratories. Further tests will be conducted in a test apartment, where a prototype of the duct system will be installed. In cooperation with Tetex Konsulter AB, pressure drops and air flows were measured to evaluate the performance of the different duct configurations. These results will confirm the sizing of the air supply fans to meet required indoor air quality. As with every air duct installation, the sound the air makes in the ducts must be observed. High sound levels in the ducts would cause tenants unnecessary nuisance and therefore must be eliminated. The experiments conducted will also cover sound tests in the laboratory and at the test apartment. Equipment: The following is the equipment and instruments used in the experiments.
