Experimental study on the impact of using a fan coil in the evaluation of contaminant removal effectiveness of common air diffusion strategies
Publication . Monteiro, Joaquim; Bathelt, Amadeusz; Castro, Olga
The aim of this study is to investigate the differences in ventilation efficiency owing to an air supply position and air exhaust locations of an air distribution system in combination with a fan coil. Ten strategies of air diffusion strategies were performed in a test chamber applying the tracer gas techniques. All experiments were performed with a presence of the fan coil. For all the ten strategies 9 rph provided by a fan coil was investigated. Three strategies were studied with other renovations rates (6, 7 and 8 rph). For 3 strategies influence of different position of CO2 probes on the final results was checked. The main conclusions of this work are as follows: if the renovation rate is over 7 rph, the contaminants and temperature vertical distributions are destroyed due to mixing of the air; if fan coil provides renovations over 7 rph, the efficiency for every strategy approaches 1; placement of temperature and contaminant probes has an influence on the result of the experiment for particular strategies.
