<p>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 connected with ducts are provided in the divided two sections, 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 port 5 and th open air enters the room through a vent port 3, a duct 9, a heat insulating duct 7, a duct 16 and a vent port 14. On the other hand, a negative pressure generates at the leeward vent port 6 so that the open air introduced into the room is discharged outside the room through a vent port 13, a duct 17, a heat exchange duct 8, a duct 10, a vent port 4 and the vent port 6. Accordingly, the same quantity of the open air is sucked into, and discharged outside, the room due to the action of the wind and in this case, a heat exchange operation is performed by the heat exchange duct 8 so that the resultant heat is transferred to the room. Further, when the heat exchange operation is on, the room is dehumidified to a suitable degree at the same time.</p> |
