17, an air supply blade 18 for blowing air to the air supply passage 16, and a ventilation motor 19 for rotating them, and an exhaust passage
A heat exchanger 20 is provided at the intersection of 13 and the air supply passage 16.

Reference numeral 21 is a chamber unit whose interior is divided into an exhaust chamber 22 and an air supply chamber 23, and a ventilation exhaust port 24 of the air conditioning unit 1
And the exhaust port 11 of the ventilation unit 10 are connected by the exhaust chamber 22, and the ventilation air supply port 5 of the air conditioning unit 1 and the ventilation unit
An air supply chamber 23 communicates with the ten air supply ports 15.

The indoor air inlet 2 of the air conditioning unit 1 and the air inlet 26 provided in each room are communicated with each other by a return air duct 25, and the air conditioning unit 1
The indoor discharge port 3 and the discharge port 28 provided in each room are connected by an air supply duct 27. An exhaust duct 29 connects the exhaust chamber 22 and an exhaust inlet 30 provided in a toilet or washroom. The ventilation exhaust port 24 of the air conditioning unit 1 is provided with a wind pressure damper 31 to prevent air from flowing from the exhaust suction port 30 to the ventilation exhaust port 24.

When the motor 8 and the ventilation motor 19 are operated in the above configuration, the indoor air in each room is sucked into the air conditioning unit 1 through the suction port 26 and the return air duct 25 as shown by arrow A →, and a part of the air is exhausted from the ventilation port 24. , Through the exhaust chamber 22, the exhaust port 11 of the ventilation unit 10 and through the heat exchanger 20 by the exhaust vanes 17 to the outside from the outdoor outlet 12 as shown by arrow B →, and most of them are blower vanes. 7 and heat exchange coil 9
After being heated or cooled by the air intake blade 14 of the ventilation unit 10 by the air supply blade 18 as shown by an arrow C ... →
After being heat-exchanged with the air that has been sucked in and exhausted by the heat exchanger 20, the air that has been heated or cooled by the heat exchange coil 9 through the air supply port 15, the air supply chamber 23, and the ventilation port 5 of the air conditioning unit 1 Combines with air, indoor discharge port 3, air supply duct
It is discharged to each room through the discharge port 28 from the discharge port 28 as shown by arrow D →. Further, the air in the toilet or washroom is sucked in through the exhaust suction port 30 as shown by arrow E →, passes through the exhaust duct 29, and joins with the air from the ventilation exhaust port 24 of the air conditioning unit 1 in the exhaust chamber 22 to form the ventilation unit. The air is exhausted to the outside of the room as indicated by arrow B → through the heat exchanger 20 by the exhaust blades 17 through the exhaust port 11 of 10.

As described above, according to the present embodiment, the air from each room is sucked into the air conditioning unit 1, a part of the air is exhausted to the outside by the ventilation unit 10, and most of the air is supplied together with the outdoor air supplied by the ventilation unit 10. The air from the toilet or washroom is heated or cooled by the heat exchange coil 9 and discharged into each room.
Since it is sucked into and exhausted to the outside of the room, it is possible to ventilate and heat or cool each room without the odor of the toilet and the humidity of the toilet moving to and diffusing into each room. Further, when the suction port 26 of each room is clogged, the air in the toilet or washroom may flow back from the ventilation / exhaust port 24 of the air conditioning unit 1 to the circulation passage 4 of the air conditioning unit 1, but in this embodiment, ventilation / exhaustion is performed. Since the wind pressure damper 31 for preventing backflow is provided at the mouth 24, the wind pressure damper 31 closes the ventilation exhaust port 24 of the air conditioning unit 1 as shown in FIG. 2 to prevent the odor of the toilet and the humidity of the washroom. It is possible to prevent diffusion to each room via the air conditioning unit 1.

EFFECTS OF THE INVENTION As is apparent from the description of the above embodiments, the present invention provides a passage for exhausting air in a toilet or a washroom separately from the circulation passage, and exhausts all air in the toilet or washroom to the outside. This prevents odors from the toilet and humidity in the washroom from diffusing into each room, improving comfort and preventing dew condensation in each room, as well as ventilation and heating in each room. Alternatively, there is an effect that cooling can be performed.
