Based on the actual residential kitchen and cooking process,a physical model was established and CFD simu-lation of the kitchen environment was carried out,and the simulation results were in good agreement with the measured results.A kitchen environment optimization strategy based on dedicated air conditioning equipment,double-vent hoods and air curtains was proposed,and numerical simulations were conducted to compare and analyze the environment before and after optimization.The results show that after optimization,the average temperature of the preparation stage in summer decreased by 15.7％,the average temperature of the cooking stage decreased by 20％,the average concentration of CO2 a-round the human body is close to 380 ppm,and the average concentration of grease smoke in the human body's respiratory area was close to 0 ppm.After optimization,the average temperature of the preparation stage in winter increased by 65.4％,the average temperature of the cooking stage increased by 136％,and the average temperature of human respiratory area is close to 0 ppm,increased by 136％,the average concentration of CO2 in the human breathing zone was less than 500 ppm,and the average concentration of oil smoke in the human breathing zone is close to 0 ppm.
