Thermal environment and air flow condition in small assembly room at typical summer weather was studied by numerical simulation and experiment. Numerical simulation was based on the indoor zero-equation turbulence model using momentum method and N-point model as boundary condition of air supply opening respectively. It was found that the N-point model at N=3 as inlet boundary condition to simulate louver supply opening with certain angles gives a good simulation result. A method of simulating heat-gain by solar radiation was proposed. It gives considerable comparable temperature gradient above 0.2 m height. Ultimately, the thermal comfort evaluation was given as separated air-conditioning unit supply low temperature air to the room.
