This paper deals with the performance evaluation of three types of low-level ventilation systems: the wall displacement ventilation, the floor displacement ventilation and the impinging jet ventilation systems. The comparison between the performances of these three systems is based on air movement, comfort assessment, mean age of air and ventilation efficiency for contaminant removal. Data from measurements and CFD simulations are used for comparisons. The paper is part of an ongoing research to develop an alternative method of air distribution that has the advantages of displacement ventilation without its disadvantages.
