Abstract
A system and method for ventilating a room in which the system has at least one air supply unit and one air exhaust unit. The air inlet unit has a guiding slot diffuser for guiding an airstream in a certain direction, such that a patient, lying down in a bed on his back, receives the airstream frontally. The exhaust unit is arranged near the floor and near a head end of the bed such that air is arranged to leave the room after having ventilated the patient. The air supply unit is also provided with a booster fan arranged in air communication with the guiding slot diffuser such that fresh air can be forced through the diffuser by the aid of the booster fan forming a first an airstream. The first airstream leaves the diffuser bringing with it a larger mass of fresh air leaving the air supply unit via perforated sheets, forming the airstream devised to cool the patient.
