The wind deflector is one of the indigenous elements that is widely used in hot, hot, dry and hot humid climates, especially in the Middle East countries. A system consisting of a wind deflector and a solar chimney has been designed. The purpose of this simulation with CFD is to compare the performance of the wind deflector in the presence of a solar chimney. The simulation is carried out in the range of 0° for a uniform wind velocity of (0.6 m/s -1.5 m/s ) the entrance boundary condition is inlet velocity and the exit boundary condition is outlet pressure. The dimensions of the room connected to the system are 1.5 * 1.25 * 1m (length, width and Height). This room is a closed room with no opening. The lower part of the chimney (back to the wind) is blocked. The absorber plate is a dark aluminum plate with a light absorption coefficient of 90%. The rest of the walls of the system are isolated and the system is adiabatic. Due to the effect of the buoyancy force in the natural movement of air in the wind-solar chimney, it has a greater effect in reducing the room temperature. Also, the decrease in humidity occurred at low air speeds in a tangible way, and the buoyancy force caused by the solar chimney is more obvious.
