PURPOSE:To provide an indoor ventilation method of which installing expenditure and maintenance expenditure are less expensive and a silent ventilation of an entire room can always be carried out and further it may be operated even under no air condition by a method wherein more than two ventilation ports having a heating source are attached to a slant or vertical aeration circuit. CONSTITUTION:Ventilation ports A with a heating source are constructed such that a heating source 2 such as heater and the like is set at a slant aeration circuit 1. So, when surrounding cold air enters a room 4 through ventilation ports having a heating source, the air is heated and thus an interior temperature is not decreased. An aeration circuit 1 at the ventilation port A having a heating source at the lower part of the room 4 ascends from outside toward an interior of the room. Due to this arrangement, surrounding atmosphere is taken into the indoor area through heat of the heating source 2 and then ascending air flow is generated. In turn, the aeration circuit 11 for the ventilation port A having a heating source attached to the upper part of the room 4 ascends from an interior side to the outside part. Due to this fact, indoor air is discharged due to heat of the heating source 2 and then the ascending air flow discharged out of the room is generated. Thus, in case of no air, an air flow indicated by an arrow is generated and ventilation of the interior area is carried out. |
