PURPOSE:To ventilate rooms by a method wherein a ventilating means is provided in a dual duct with branch ducts to ventilate spaces through a main air supply duct and a main exhaust duct. CONSTITUTION:There are a living room 12a, a bath room 12b, a kitchen 12c and others which respectively form a living room space 31, a bath room space 32, a kitchen space 33 and others, and a dual duct 16 consisting of a main air supply duct 17 and a main exhaust duct 18 is furnished. Air supply branch ducts 21, 24 and 26 which respectively connect the main air supply duct 17 and the spaces 31, 32 and 33, and exhaust branch ducts 23, 25, and 27 which respectively connect the main exhaust duct 18 and the spaces 31, 32 and 33 are furnished between the dual duct 16 and the rooms 12a, 12b and 12c. A ventilation fan 20 is installed in the dual duct 16 to ventilate the spaces 31, 32 and 33 through the main air supply duct 17 and the main exhaust duct 18. Thereby, the rooms 12a, 12b and 12c can be ventilated by the single ventilation fan 20.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner suitable for an air supply / exhaust system having a small air supply / exhaust amount such as an air supply / exhaust system in an individual house of an apartment house.

[0002]

2. Description of the Related Art Conventionally, a small air supply / exhaust system such as an air supply / exhaust system in an individual house of an apartment house uses a forced exhaust device such as a ventilation fan only in a key place such as a kitchen or a toilet, and a living room or the like. It was common for other rooms to rely on windows and registers.

[0003]

However, in consideration of comfort of living space, there is also a demand for ventilation of rooms other than kitchens and toilets such as living rooms. Therefore, like an air supply / exhaust system of a building, etc., an air supply fan and an exhaust fan are provided outside the house, and an air supply duct and an exhaust duct connected to each fan are provided in the house and branched from the duct. It is conceivable to introduce a branch duct into each room such as a living room, kitchen, and toilet. However, when such a large air supply / exhaust system is applied to the small air supply / exhaust system, the installation space of the air supply / exhaust system is large, which causes a problem that the living space is reduced. In view of the above circumstances, an object of the present invention is to provide an air conditioner capable of adjusting air in a room other than the kitchen or the toilet, such as a living room, without reducing the living space. I am trying.

There is provided a controller 12c4 capable of controlling the 2

Since the air conditioner 1 has the above-described structure, first, as shown in FIG.
The drive start signal S1 is output to the air supply / exhaust fan 20 by turning on the main power supply 12a5 of 2a4, the main power supply 12b5 of the bathroom controller 12b4, or the main power supply 12c5 of the kitchen room controller 12c4. Then, the air supply / exhaust fan 20 causes the drive start signal S1.
Based on the above, the driving is started, and the inside air IA in the exhaust passage 18 of the composite duct 16 is forcibly discharged to the outside. Here, the exhaust path 18 communicates with the living room 12a through the branch exhaust path 23a and the exhaust port 12a3, communicates with the bathroom 12b through the branch exhaust path 25a and the exhaust port 12b3, and branches exhaust path 27a and the exhaust port. It communicates with the kitchen 12c through 12c3. Therefore, by discharging the inside air IA in the exhaust passage 18 to the outside, the inside air IA of the living room 12a, the inside air IA of the bathroom 12b, and the kitchen 12 are provided in the exhaust passage 18.
The inside air IA of c flows in, and the inside air IA is supplied to the air supply / exhaust fan 20.
Is discharged outdoors. Thus, in the living room 12a, the bathroom 12b, and the kitchen 12c, the smell of pets, the smell of grilled fish, and the air contaminated by a heating device can be discharged to the outside. In addition, due to this, the living room 12
The pressure in a, the bathroom 12b, and the kitchen 12c decreases. Here, the living room 12a, the bathroom 12b, and the kitchen 12c are provided with air supply ports 12a2, 12b2, 1 respectively.
2c2 is provided, and the air supply ports 12a2, 12b2,
12c2 are branch air supply passages 21a, 24a, 2 respectively.
It is connected to the air supply passage 17 of the composite duct 16 via 6a, and the air supply passage 17 is open to the outside via the opening / closing valve 19a of the variable air volume damper unit 19. Therefore, due to the pressure difference between the outside and each room, the living room 12a and the bathroom 12
b, fresh outside air OA from the outside flows into the kitchen 12c and the kitchen 12c, respectively. Therefore, the air in the living room 12a, the bathroom 12b, and the kitchen 12c can be always kept fresh. In addition, each room 12a, 12b, 12c
Controller 12a4, 12b4, 12c provided in
When the adjusting switches 12a7, 12b7, 12c7 of No. 4 are adjusted, the total air supply amount change command S2 is output to the variable air volume damper unit 19 provided at the north end of the air supply passage 17,
The variable air volume damper unit 19 changes the opening ratio of the air supply passage 17 by the valve 9a based on the signal S2, so that the air supply amount from the outside to the air supply passage 17 can be adjusted. Further, for example, when it is desired to adjust the air supply / exhaust volume for each room 12a, 12b, 12c, such as ventilation because the fish is grilled in the kitchen 12c, the room 12c (1
2a, 12b) controller 12c4 (1
2a4, 12b4) adjustment switch 12c6 (12a
6, 12b6). Then, the room 12c (1
2a, 12b) air supply port 12c2 (12a2, 12b)
2) and the small variable air volume damper unit 22 provided at the exhaust port 12c3 (12a3, 12b3), the supply / exhaust amount change command S3 is output. Then, the small variable air volume damper unit 22 to which the supply / exhaust volume change command S3 is input is
By adjusting the opening ratio of the valve 22a based on the supply / exhaust amount change command S3, the supply / exhaust amount in the room 12c (12a, 12b) is adjusted. Therefore, each room 12a, 1
The supply / exhaust flow rate can be appropriately adjusted for each of 2b and 12c. When it is desired to stop the air supply / exhaust fan 20 and switch to passive, that is, non-forced ventilation, as shown in FIG. 2, the main power source 12a of the living room controller 12a4 is switched.
5, or the main power supply 1 of the bathroom controller 12b4
2b5 or the main power supply 12c5 of the kitchen room controller 12c4 is turned "OFF", the air supply / exhaust fan 2
When the drive stop signal S11 is output to 0, the air supply / exhaust fan 20 stops its drive based on the drive stop signal S11. As shown in FIG. 1, since the composite duct 16 is provided with the air supply passage 17 and the exhaust passage 18 in one composite duct 16, by installing it in the corners between the ceiling space 14 and the boundary wall 6d, It can be installed in a small installation space. In addition, each room 12a, 1
Since the ventilation of 2b and 12c can be performed at the same time,
Only one air supply / exhaust fan 20 may be installed on the balcony 9 or the like. Therefore, a large installation space is not required.
Therefore, the air conditioning apparatus 1 of the present invention can be installed in a small installation space and does not reduce the utilization space.

In the air conditioner 1 of the above embodiment, as shown in FIG.
2a is provided with a branch duct 30 and a cooling / heating apparatus main body 29 is connected to the duct 30.
As shown in FIG. 3, 9a is guided to the outside through the inside of the branch duct 30 and the composite duct 16 and is connected to the outdoor unit 29b provided on the veranda 9 as shown in FIG. Instead, it is possible to adjust the room temperature, and always maintain a comfortable room temperature.
