Embodiment Construction

[0025] A preferred embodiment is shown in Figures 1a and 1b. The room 101 with the walls 103 , the suspended ceiling 105 and the floor 107 is provided with an air-conditioning system including at least one air supply unit 120 and at least one low-speed exhaust unit 130 . The air supply unit 120 is located in the ceiling 105 above the hospital bed 140 and is used to supply conditioned air to the patient 150 on the hospital bed 140 .

[0026] Figures 2a and 2b show the blower unit 120 of the present invention in more detail. The air blowing unit 120 is provided with an inlet 121 , a guide slit diffuser 122 , a booster fan 124 and an air filter 125 , an opening for placing a filter 126 , some orifices and a lighting unit 128 .

[0027] Air is supplied from the control system to the blower unit 120 . Air enters through inlet 121 and passes through filter 125 where particulates are removed. The air is then diffused inside the blower unit 120 . A portion of the air enters the su...

Abstract

The invention provides a system and method for ventilating a room having walls , a floor and a ceiling, and being capable of housing a patient's bed, comprising at least one air supply unit and one air exhaust unit, where said air inlet unit comprises a guiding slot diffuser for guiding an airstream in a certain direction, such that a patient, lying down in said bed on his back, receives said airstream frontally, and that said exhaust unit is arranged near the floor and near a head end of the bed such that air is arranged to enter the portable air conditioning unit after having ventilated the patient. The air supply unit is also provided with means such that fresh air can be forced through the diffuser forming a first airstream and that said first airstream leaves the diffuser bringing with it a larger mass of fresh air leaving the portable air supply unit via perforated sheets, forming the airstream devised to cool the patient.

Description

[0001] The present invention is a divisional application whose Chinese invention patent application number is 03823919.1, the title of the invention is ventilation system, device and method, and the international filing date is September 4, 2003. technical field [0002] The present invention relates to an air conditioning system, especially a device and method for providing ventilation and air conditioning in hospitals or other places with high requirements for clean air. Background technique [0003] As the airflow in the air conditioning system increases, the risk of disturbances increases and the risk of entraining infectious agents that infect patients in eg a hospital ward increases. Such risks are more pronounced in tropical countries where larger cold airflows are generally required to cool patients for comfort. [0004] A method and apparatus for supplying clean air to an operating room is disclosed in WO 86 / 06460 to Nilsson. The apparatus comprises: a central supp...
