Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to an air conditioner using an air conditioner such as an air handling unit or a package type air conditioner.

[0002]

2. Description of the Related Art Referring to FIG. 21, conventionally, each air conditioner 3 for air-conditioning each floor 2 of a building 1 is installed in a machine room 4 provided on one floor of each floor 2. The outside air is taken into each of the air conditioners 3 through each of the outside air ports 6 provided on the wall surface 5 of the building 1, and the exhaust air is discharged through the wall surface 5
It was discharged to the outside through each exhaust port 7 provided in the.

[0003]

Conventionally, the outside air outlet 6 and the exhaust outlet 7 of each air conditioner 3 are the same wall surface 5 of the building 1.
21. Therefore, as shown by the broken line arrow in FIG. 21, for example, heat exchanged and dirty exhaust air discharged from the exhaust port 7 in the air conditioner 3 provided on the lower floor is provided on the upper floor. It was taken into the air conditioner,
There is a problem that the performance of the air conditioner on the upper floor is degraded and the indoor environment is deteriorated.

Further, if the machine room 4 is provided in one screen of each floor 2 and each air conditioner 3 is installed, there is a problem that the floor area of each floor 2 is narrowed. Therefore, a main object of the present invention is to provide an air conditioner capable of maintaining the performance of the air conditioner, preventing the deterioration of the indoor environment, and effectively utilizing the floor area of the building.

[0005]

According to the present invention, there are provided a plurality of air conditioners each including a casing and an exhaust port and an outside air port formed in the casing and sequentially arranged in a vertical direction, and a plurality of air conditioners. An air conditioner having an exhaust duct communicating with each of the exhaust ports of the machine and having the air conditioner and the exhaust duct installed outside the building.

[0006]

A plurality of air conditioners are sequentially arranged outside the building in the vertical direction, and the exhaust port of each air conditioner is connected to a common exhaust duct provided outside the building. Then, the exhaust air from each air conditioner is discharged to the outside through the exhaust duct. Furthermore, the inside of the exhaust duct will be used as a space for maintenance and inspection of the air conditioner and a space for piping and wiring.

[0007]

According to the present invention, since the exhaust gas can be discharged outdoors by passing through the exhaust duct at a position sufficiently distant from the outside air outlet of each air conditioner, the exhaust gas is taken into the air conditioner again. The air conditioner performance can be maintained and the indoor environment can be prevented from deteriorating. Moreover, since the air conditioner and the exhaust duct are installed outside the building, it is possible to effectively utilize the floor area.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

To be done. A damper 60 is provided at the outside air port 58. An air filter 62 is provided at the boundary between the chamber 32 and the chamber 34 such that its main surface extends in the horizontal direction, and inside the chamber 34, the heat exchange coil ( Cold / hot water 64 (FIG. 5) and humidifier 66 are arranged parallel to each other. A fan 68 and a motor 70 for driving the fan 68 are arranged above the chamber 34, and a discharge port 72 of the fan 68 is connected to an opening 74 formed in the partition wall 24.

On the front surface of the chamber 36, that is, on the upper left side of the front surface of the casing 14, an air supply port 76 (2 in FIG. 4) is provided.
(Shown by a dotted chain line) is formed, and further, on the front surface of the casing 14, an inspection door (not shown) for performing inspection and replacement of each air conditioner arranged inside the casing 14 is provided. Therefore, the inside of the air conditioner 12 is not shown in FIG.
An air passage is formed as shown in FIG.

Returning to FIGS. 1 to 3, each of the air conditioners 12 thus constructed is separated from the outer wall 82 of the building 78 by a predetermined distance so as to correspond to each floor 80 of the building 78. Are installed continuously in the vertical direction. And
Side plates 84 and 86 (FIG. 2) that define a space between the outer wall 82 of the building 78 and each air conditioner 12 are continuously formed in the vertical direction, whereby the outer wall 82 and each air conditioner 12 are formed. A vertically continuous exhaust duct 88 is formed therebetween.

A substantially "J" -shaped hood 90 is installed at the upper end of the exhaust duct 88, and each air conditioner 12 is
The return air port 38 and the air supply port 76 are connected to the return air duct 92 and the air supply duct 94 arranged on each floor 80 via connecting ducts 96 and 98, respectively, as shown in FIG. In addition, the wall surface of each floor 80, that is, the building 7
A door (not shown) is formed on the wall surface of the exhaust duct 8
A deck 100 corresponding to the door is formed inside 8 to serve as a scaffold for maintenance and inspection. As the deck 100, a suitable one that allows exhaust gas to pass therethrough can be used, but in this embodiment, expanded metal (FIG. 2) is used.

Further, in the exhaust duct 88, a pipe 101 is provided.
And wiring are laid (Fig. 2). In each of the air conditioners 12 constituting the air conditioner 10, when the fans 40 and 68 are driven by the motors 42 and 70, air flows as indicated by arrows in FIGS. 1, 2 and 4 to 7. That is, the return port 38 through the connecting duct 96.
The air taken into the casing 14 (chamber 26) from the inside is sent out into the chamber 28 by the fan 40, and the damper 5
2 and 54 to chambers 30 and 32 respectively. The air distributed to the chamber 32 is mixed with the outside air flowing in from the outside air port 58, passes through the air filter 62, and the chamber 3
Be led into 4. Then, it is heated or cooled by the heat exchange coil 64 and humidified by the humidifier 66 as needed. Note that cold water is passed through the heat exchange coil 64 during cooling, and hot water is passed during heating. The air that has been air-conditioned such as dust removal, heat exchange and humidification in this way
The air is taken into the fan 68, discharged from the opening 74 into the chamber 36, and discharged from the air supply port 76 through the connecting duct 98 and the air supply duct 94 into the room to be conditioned.

On the other hand, the air distributed to the chamber 30 by the damper 52 is discharged from the exhaust port 56 into the exhaust duct 88, and is discharged outdoors through the hood 90 provided at the upper end of the exhaust duct 88. According to this embodiment, since the exhaust gas discharged from the exhaust port 56 into the exhaust duct 88 is discharged outside from the hood 90 provided further above the uppermost air conditioner, the exhaust gas is air-conditioned. It can be prevented from being taken into the machine 12 again, and the deterioration of the indoor environment as a whole can be prevented.

Since each air conditioner 12 is installed outside the building 78, the effective space in the building is not narrowed. The air conditioners 12 are not limited to those of the above-described embodiment, and for example, the air conditioner 102 shown in FIGS. 8 to 10 and the air conditioner 1 shown in FIGS. 12 to 14.
