The effect of make-up air system on the performance of oil fume collection in commercial kitchen
Abstract
Make-up air and exhaust system dominates the airflow pattern in the commercial kitchen. In this paper, the numerical simulations were performed to analyze and compare the effect of different make-up air modes on the flow field characteristics, the temperature and concentration of C19H30 distribution and the collection efficiency of fume particles. It was shown that air curtain supply can prevent oil fume from spreading out more effectively than ceiling supply (CS) mode. It improves primary collection efficiency when the exhaust airflow rate is less than 4500m3/h in upward air curtain supply (UACS) and 4000 m3/h in downward air curtain supply (DACS) mode, respectively.
