Abstract: To address the critical challenge of maintaining kitchen thermal comfort while mitigating the interference of conditioned air on cooking-fume capture, this study employs an air-conditioned integrated stove as a representative case. Based on orthogonal experimental design, numerical simulations were conducted to evaluate the effects of various supply-air parameters on fume-capture efficiency under active ventilation. Spatial contaminant concentration was adopted as the primary performance indicator, revealing that exhaust flow rate, supply-air outlet width, supply-air temperature differential, baffle angle, baffle width, and supply-air velocity constitute the key influencing factors. Subsequent single-factor analyses systematically elucidated the quantitative relationships between each parameter and fume-capture effectiveness, enabling the identification of an optimal supply-air configuration characterized by markedly reduced spatial contaminant levels. Validation via Predicted Mean Vote (PMV) assessments across occupant body regions confirmed that the proposed parameter set simultaneously satisfies human thermal-comfort criteria in kitchen environments. The findings provide scientifically grounded design guidelines for key parameters in air-conditioned integrated stoves and offer a replicable methodological framework for reconciling the inherent conflict between thermal-comfort enhancement and fume-capture integrity in residential kitchens.
