DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air intake and exhaust system for an individual air conditioner.

BACKGROUND ART Conventionally, the air intake and exhaust air during cooling and heating operation of an individual air conditioner installed in a perimeter zone of a building or the like has been configured as shown in FIG. A main body 2 of the individual air conditioner installed on a waist wall below a window 1 consists of an indoor unit part 3, a total heat exchange unit part 4, and an outdoor unit part 5. In the outdoor unit section 5, outside air flows in as shown by arrows A and B by the operation of an outdoor blower 6, and the outdoor heat exchanger 8 provided above the motor fixing plate 7 flows in the direction shown by arrow C.
A part of the outdoor air that has passed through the main passage as shown in the figure and is exhausted outdoors as shown by arrow D, and a part of the outdoor air that has gone around above the motor fixing plate 7 is connected to the first opening of the partition plate 9 as shown by arrow E. 10, fresh air is blown into the room as indicated by the arrow F of the air outlet 13 while being induced by the operation of the indoor heat exchanger 15 of the indoor unit part 3 via the total heat exchanger 11 of the total heat exchange unit part 4. On the other hand, in the indoor unit section 3, the indoor air sucked in from the bottom as shown by arrow G passes through the air filter 14.
The flow path passes through the indoor blower 12, the indoor heat exchanger 15, and is blown into the room from the outlet 13, and the total heat flows upward as shown by arrow H, flowing from the bottom surface of the total heat exchange unit 4. It passes through the exchanger 11, goes further downward, is attracted by the outdoor blower 6 through the second opening 16 of the partition plate 9, passes through the outdoor heat exchanger 8, and is exhausted outdoors as shown by arrow D. however,
The air flowing into the outdoor unit part 5 side from the second opening 16 flows to the outdoor heat exchanger 8 by the outdoor blower 6, but when it actually goes around above the motor fixing plate 7, it flows in the direction of arrow E. It also has air that mixes with the air and flows into the room along with the outside air.

In this way, conventionally, as shown by arrow H, indoor air is exhausted to the outdoors through the total heat exchanger 11 and the second opening 16 via the outdoor fan 6 and the outdoor heat exchanger 8, while the intake of outdoor air is Air flows in as shown by arrows A and B, flows from above the motor fixing plate 7 as shown in arrow E from the first opening 10, passes through the total heat exchanger 11, and enters the indoor unit section 3, and is sucked into the room through the air outlet 13. It was hot.

Problems to be Solved by the Invention In such a conventional configuration, in terms of the balance between the intake amount and the exhaust amount, the first
The opening 10 and the second opening 11 are connected to the outdoor unit 5.
Since it is open toward the inside, the amount of intake air and the amount of exhaust air are unbalanced. In other words, as shown by arrow E, outside air is sucked in by the outdoor blower 6, and a portion of the sucked air is taken in through the first opening 10, even though it is desired to increase the amount of intake air compared to the exhaust amount. , it is not possible to secure a sufficient amount of intake air by inducing the indoor fan 12, and depending on the indoor floor plan of the building, even though it is desired to maintain a balance between intake and exhaust air pressure so that the indoor air pressure is high, the exhaust There was a problem in that the amount of gas increased and the atmospheric pressure in the room became low.

The present invention solves these problems,
The purpose is to increase the amount of intake air compared to the amount of exhaust air to make the indoor air pressure higher, to prevent a drop in indoor air pressure due to an imbalance in intake and exhaust air, and to avoid inducing drafts. .

Means for Solving the Problem In order to solve this problem, the present invention provides a main body of an individual air conditioner consisting of an outdoor unit part, a total heat exchange unit part, and an outdoor unit part, A partition plate on the outdoor unit side that partitions the replacement unit part, and a duct connected to the opening of the partition plate and drawn by the indoor blower and extended to the outdoor blower side of the outdoor unit section, It has an opening on the end face and an opening on the lower end face.

Function With this configuration, the outside air sucked in by the outdoor blower is drawn into a large amount of outside air by the indoor blower through the duct having a side end face opening and a bottom end face opening, and the total heat exchange unit is used for total heat exchange. Air is taken into the room from the indoor unit through the device.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The main body 21 of the individual air conditioner installed on the waist wall below the window 20 of the building includes an outdoor unit section 22, a total heat exchange unit section 23,
It consists of an indoor unit section 24. The outdoor unit section 22 is provided with an outdoor blower 26 that is integrated with a motor fixing plate 25, and an outdoor heat exchanger 27 that is provided at an angle. Above the discharge port 28 of the outdoor blower 26 is connected to the opening 30 of the partition plate 29 of the total heat exchange unit 23 and the outdoor unit 22 is connected to the opening 30 of the partition plate 29 of the total heat exchange unit 23.
A duct 31 extending inside is provided. This duct 31 has a side end opening 31a and a lower end opening 31c, and a part of the air discharged from the outlet 28 of the outdoor blower 26 is guided to the total heat exchanger 32 side through the duct 31. flows. The indoor unit section 24 includes an air filter 33 on the suction side and an indoor heat exchanger 35 provided at an angle above the indoor blower 34.
It has an air outlet 36 on the top side. A compressor 37 is provided in the compressor room on one side. Further, the partition plate 29 is provided with a second opening 38, which serves as an exhaust flow path for indoor air. Note that the flange 39 provided on the duct 31
is for fixing to the partition plate 29.

In the above configuration, when the individual air conditioner is operated, outside air is sucked into the outdoor blower 26 through the sleeve as shown by arrow A, passes through the outdoor heat exchanger 27 as shown by arrow B from the discharge ports 28 of both casings, and
A main flow path is formed as indicated by arrow C to exhaust the air to the outside. Then, from the discharge port 28, the outdoor heat exchanger 27
A part of the air flowing into the duct 31 flows from both the side end surface opening 31a and the bottom end surface opening 31b in the directions shown by the arrows D and E.
A large amount of outside air passes through the opening 30, passes through the total heat exchanger 32, reaches the indoor unit section 24, passes through the indoor heat exchanger 35, and is blown into the room from the outlet 36. Air flowing from the duct 31 through the total heat exchanger 32 into the indoor unit section 24 is induced by the operation of the indoor blower 34.

In the indoor unit section 24, indoor air is sucked in from below as shown by arrow F, passes through an air filter 33, reaches an indoor blower 34, passes through an indoor heat exchanger 35, and is blown into the room from an outlet 36 as shown by arrow G. Ru. On the other hand, in the total heat exchange unit section 23, the indoor air is sucked in from below as shown by arrow H, flows upward, passes through the total heat exchanger 32, once goes around downward, and enters the outdoor unit section through the second opening 38 of the partition plate 29. 2
2, and here, by the outdoor blower 26,
The outdoor heat exchanger 2 passes through the discharge port 28 as shown by arrow B.
7 and exhaust outdoors as shown by arrow C. Note that the exhaust air discharged from the discharge port 28 may mix with the fresh air flowing in from the outdoors to some extent, but the outdoor blower 26 has a larger capacity than the indoor blower 34, and the duct 3
1 is located on the front side of the outdoor unit part 22, and the side end surface opening 31b and the bottom end surface opening 31b are configured narrow and thin in the depth direction of the main body 21, so that they can be almost ignored and the displacement is small. However, even if it returns again, the amount of intake air and exhaust air will still be slightly larger. The point is that the duct 31 acts like a hood to draw in more air.

The duct 31 is fixed to the partition plate 29 using the screw hole 40 of the flange 39, but if a large amount of intake air is not required due to the room division of the building, etc.
This duct 31 is designed to be removable.

Effects of the Invention As described above, the present invention has a duct that is opened in the partition plate on the outdoor unit side that partitions the total heat exchange unit and is drawn by the indoor blower, and that the duct that is extended to the outdoor blower side of the outdoor unit is installed on the side. Since the end face opening and the lower end face opening are opened so that the outside air sucked in by the outdoor blower is intensively drawn into the duct by the indoor blower, the intake air volume can be increased compared to the exhaust volume. This also prevents the indoor air pressure from being lower than the outdoor air pressure. Therefore, a balance can be achieved in which the indoor air pressure is slightly higher to make the room more comfortable, and the duct can also be removed if a large amount of intake air is not required due to the building's zoning structure. It has the following effects.
