Abstract

PURPOSE:To make it possible to discharge the air in a living room efficiently to the corridor by providing an indoor ventilator which forms an air circulation channel for sending air to a heat exchanger for heat recovery through an air discharge duct with a guide hole which leads the air in the living room to the corridor. CONSTITUTION:Supply air is led to the space of a downward tilting ceiling 3 which becomes a supply air channel and the supply air is led to the inside of a living room 4 through an air introduction port 8 provided in the side wall of the downward tilting ceiling 3. On the contrary the air in the living room 4 is discharged to a corridor section 5 through guide holes 11 and 12 which are provided in a door 9 or partition 10 or others which partition the living room 4 and corridor section 5. The air that is discharged to the corridor section 5 is led to a sanitary section 6 through a hole or slit which is provided in the door or partition or the like provided in the sanitary section 6 or by an air discharge fan installation or by natural flow, and the air concentrates in the sanitary section and is discharged from an air discharge duct 7. With this arrangement it becomes possible to prevent the leakages of the sound and light from the living room by providing the guide hole and discharge the air in the living room efficiently which is a large factor for the realization of a ventilator in the living room.
