JPS6433449A - Indoor ventilator - Google Patents

Abstract

PURPOSE:To provide an indoor ventilator which can be easily installed by making the outside air sucked from a heat exchanger for heat recovery and blast fan pass through the inner space of a downward tilting ceiling and recovering the air from a living room through the corridor section to a sanitary section and sending the recovered air to the heat exchanger for heat recovery through a discharge air duct. CONSTITUTION:Supply air from a blast fan 2 is made to flow through the space of a downward tilting ceiling 3 which becomes a passage for the supply air, and the supply air is led into a living room 4 through an introduction hole 8 that is provided in the side wall of the downward tilting ceiling 3. Conversely the air in the living room 4 is discharged from a discharge port 9 provided in a door or partition which separates the living room 4 from a corridor section 5 toward the corridor section 5. The air discharged to the corridor section 5 is led to a sanitary section 6 through a hole, slit or the like provided in the door or partition of the sanitary section 6 or by a discharge fan or by natural flow, and in the sanitary section the air is concentrated and discharged by a discharge air duct 7. It is, therefore, possible to give indoor ventilation of central air conditioning system which is efficient and easy to install.
