| With the deepening of economic reforms.people in the living standard have growth.enjoy good health and zing more require for the quality of life. Good health did not just confined to withed sickness puzzle.Far and wide contained receive threaten for our health.the air quality indoor contact both with those so it get wide range with pay close attention to. The cooking house to our person is very important and essential.But when we are cooking there are a lot of pollutant emerge and some waste heat those serious influence the indoor environment.Exclusive use the smoke lampblack machine to making air exhaust result in air current organization unreasonable.Making the indoor environment pollutanted even had twice pollutantion.When the smoke lampblack machine is working.The indoor production a big negative pressure.And with the effect of differential pressure.Needing to supply the air for the cooking house.Natural heritage is impose restrictions. With the Windows and doors closed.Supply the air from the Windows and doors gap.Lead to the cooking house air current organization unreasonable.Pollutanted air from cooking receive quantity of heat and air current effect run wild:Serious effect the air quality in the cooking house.Adhere to wall cabinet.Wall and some cook implement. Not only effect the beautiful of the house and making the air twice pollutantion.burning effect and work efficiency by the smoke lampblack machine also had dircect effect. Natural ventilation will be limited only by the kitchen mechanical exhaust ventilation way already cannot satisfy the requirements of the people to fresh air.In recent years.More people had a great quantity research for Prevention and cure this pollutantion.This article choose the CFD simulation technology of software fluent to civil residence indoor airflow organization with the different working condition of the simulation. According to indoor air flow of turbulent flow, The hybrid grid partition method,the structural style and the unstructural style, the pollutant air defined air and oxycarbide group.control the finite volume method will be the calculation area in discrete, with simple algorithm away.In building up the additional wind duct, do not take up too much of the construction area of the premise, the kitchen add complement tuyere, not only the smoke lampblack machine effect can be improved, and public flue header from the original design of the area is0.24mΔ, reduced to0.215m2. Fill the wind duct area is0.129m2. In building up only0.104m2for wind duct. the result is greatly different.The simulation research found that adding air from around the top of a kitchen range,it can offer air when the smoke lampblack machine is working, for indoor added some fresh outdoor air, reduce the added air from the windows and door gap,reduce exhaust energy.anywhere added some fresh outdoor air, added the fresh air in the burning of fossil fuels provides oxygen,form vertical upward air balance form pot, Reached on indoor pollutant control of the effect,enhance the smoke lampblack machine is working effect. It is an theoretical basis for the research of prevention and cure cooking house air pollutantion. |
