PURPOSE:To make it possible to ventilate a house constantly by making use of a natural wind by a method wherein a ventilating box is divided into two sections by a partition wall at the middle and vent ports each provided with a strong wind preventive valve are attached to the vent ports, respectively. CONSTITUTION:When the wind blows in the direction from the vent port 5 to the vent port 6, the pressure of the wind is applied on the windward vent port 5 attached with the strong wind prevntive valve and the open air enters the space under the roof of the house through a vent port 3, a duct 9, a heat exchange duct 8 and a vent port 13. On the other hand, a negative pressure generates at the leeward vent port 6 attached with the strong wind preventive vale and the open air introduced into the house is discharged outside from the vent port 6 through the space 15 under the floor, a vent port 14, a duct 17, a heat insulating duct 7, a duct 10 and a vent port 4. With the above structure, a heat exchange operation is performed in the heat exchange duct 8 due to the entry and discharge of the open air in and outside the house so that heat does not escape outside the house. Further, a dehumidifying operation is also performed by the system. |
