In a commercial kitchen, a large ventilation rate is needed and energy consumption can be large because a large amount of effluence of heat and moisture need to be removed. To improve kitchen environment and to save the energy, low radiative cooking equipment with concentrated exhaust chimney was developed. Although a ventilation rate may be decreased by using this equipment, the effluence needs to be captured well. To predict indoor air and thermal environment of commercial kitchen using this equipment, CFD analysis is useful. In the previous study, the capture efficiency of the hood was measured when this new equipment is used. In this paper, CFD simulation was carried out in order to analyze capture efficiency of the equipment with reproducing the measurement. CFD results of various conditions were compared with measured ones. CFD results were agreed well with measured ones for many cases.
