The Air-conditioned Room Air Parameters Numerical Simulation Of The Impact Of Indoor Air Flow

In this paper, a buoyancy-revised high Reynolds number k-ε turbulence model, wall function, and inlet model are used to establish a three-dimensional turbulence mathematical model of an air-conditioned room, and one air-conditioned room is taken as a research object. The air supply and return the same side, and the air supply side and return opposite side are aimed at, and FLUENT is used to simulate influence of air inlet parameters (air inlet velocity, air inlet direction, and the difference in temperature) in summer or in winter on indoor air velocity field and air temperature field. Moreover, laws of the air velocity and air temperature distribution inside the air-conditioned room with various air inlet parameters are studied. Consequently, instructional conclusions are provided for practical operation of an air-conditioned room.
