The Study Of Thermal Comfort In Elevator Compartment

The main function of the compartment of the lift is to transport passengers, Running speed and security performance are two important performance indexes of the lift, But with the improvement of people's living standard, the thermal comfortable sense of compartment will become an important performance index of the lift too. If you want to make the lift more comfortable you must make the airflow and the temperature field in the more reasonable. Nobody has systemically researched the problem of the lift in china and foreign country now.In this paper, the lift's temperature field and velocity field is researched through numerical simulation and experiment for the first time. The mathematics model,physics model and geometrical model for numerical simulation about lift temperature field is built based on the lift's thermal translating and substance translating theory. The method for building geometrical model and boundary condition is put forward. The numerical simulation for the lift is accomplished with the computational fluid dynamics (CFD) software of Airpark.Consulting the Norm of the lift,the standard of Ventilate and any other experiment technique on carriage, the lift's temperature field experiment technique is systemically established in the condition of no uniform criterion o the lift's temperature field and velocity field experiment at present.The numerical simulation technique and boundary condition putting forward in this paper is very reasonable by compare the numerical simulation result with the experiment result. The variation law of the temperature field and velocity field in the lift is concluded by many times of numerical simulation. The ventilate system of the lift is optimized, and the optimized project is very usable to improve it's ventilate system.It is proved that numerical simulation is a efficiency method for researching the lift's temperature field by compare the numerical simulation result with the experiment result. Numerical simulation technique has extensive purpose in the engineering.
