A numerical investigation has been carried out of cooling air distribution inside an office room with one person and other objects. Under steady conditions the three -dimensional equations of conservation of mass, momentum, energy, turbulent kinetic energy and its dissipation rate were solved under defined boundary conditions using computational fluid dynamics (CFD). Results were presented in the form of velocity vectors and temperature contours. Air movement was investigated by changing inlet and outlet locations. Comfort conditions of the person and effects due to the person and the other objects were examined.
