Using isothermal full-scale experiments and 3-dimensional CFD simulations it is investigated how normal office furniture influences the air movements in a mixing ventilated room. Two different types of inlets are used in the experiments and a set-up with normal office furniture is made. The set-up is simulated with one of the inlets where a volume resistance represents the furniture. The jet under the ceiling is investigated and it is found that the normal office furniture does not influence the air movements in the upper part of the room. In the lower part of the room the maximum velocity in the occupied zone is studied. This velocity is reduced in the furnished room compared to the empty room and the reduction increases as the total length of the furniture volume in the main flow direction increases.
