Experimental investigation of the velocity field and airflow pattern generated by cooling ceiling beams.
Author(s) : FREDRIKSSON J., SANDBERG M., et al.
Type of article: Article
Summary
The paper describes experiments conducted in a mock-up of an office to determine the airflow pattern generated by chilled beams; qualitative information was obtained by visualization. Instantaneous velocity profiles of airflow generated by the chilled beam were registered. The temperature field below the chilled beam was measured with a whole-field measuring technique. Results showed that the airflow from the chilled beam has behaviour similar to that of a two-dimensional plume but exhibits strong oscillation both sideways and along the chilled beam. These oscillations (intermittence) might cause a sensation of draught and further investigations need to be undertaken to clarify this. Air flow generated by heat sources in the room may reverse the flow generated by the chilled beam.
