Abstract

Abstract

The uniformity of the inflow of the fan coil unit in the containment cooling system was studied quantitatively by numerical simulation and experimental measurement in this paper. The flow field in the fan-coil unit was analyzed by numerical calculation. The inlet velocity data of 50 points on the windward face of the fan-coil unit were obtained by experimental measurement. The data from the measurement and the calculation were processed by using the definition of “Face Velocity Uniformity” and “Relative Standard Deviation”. The processing results quantitatively evaluated the uniformity of the inflow of the fan coil unit. The results of “Face Velocity Uniformity” did not meet the requirements in GB/T 14294—2008 for not less than 80%. The results of “Relative Standard Deviation” exceeded the requirement that the value was usually less than 15%.
