Description
Summary:When the oil fumes escape, it causes the temperature in the kitchen to rise, and the higher the temperature rises, the more the oil fumes escape. [...]when the oil fumes are not discharged smoothly, the temperature in the kitchen rises to a maximum of 315 K. The influence of heat conduction on the increase of ambient temperature is also related to the air flow in the kitchen. According to the aerodynamic characteristic curve (P-Q) of the cooker hood, to achieve a certain flow rate, the flow velocity will naturally increase. [...]the flow velocity of the exhaust port of the cooker hood has obviously increased; this also shows that the simulation results are consistent with the actual characteristics of the hood. 5. From the test results, it can be seen that the peak value of the maximum concentration on the right side is 0.26 mg/m3 , and the maximum value of the concentration of smoke on the front side is 0.30 mg/m3 . Because the simulation analysis uses the steady state calculation method, the concentration of oil fumes obtained is equivalent to the maximum of the actual concentration test of oil fumes. The error of concentration of oil fumes (2) is slightly larger, which is mainly due to the interference of air flow on the front side of the hood in the actual test environment.
