Each of the above-mentioned opening / closing lids 80a, 83, 71a-
78a may be like a single door. 1 and 4, the opening / closing lid is not shown.

How each unit is connected will be described with reference to FIGS. 1 and 4. As shown in FIG. 1, at the predetermined positions on one end side of the casings Vc, Cc, Dc, Hc of the units VU, CU, DU, HU, the upper edge side attachment member 30 and the lower edge side attachment, respectively, are provided as upper edge side attachment portions. A lower edge side mounting member 40 as a part and a side edge side mounting member 50 as a side edge side mounting part are fixed, and a casing C of each unit CU, DU, HU, FU
At a predetermined position on the other end side of c, Dc, Hc, Fc, a mounting hole 31 as a mounting portion corresponding to the upper edge mounting member 30 and a mounting portion as a mounting portion corresponding to the side edge mounting member 50 are mounted. A hole 51 is provided. By screwing the nut into the mounting screw 60 that penetrates the through hole of the upper edge side mounting member 30 and the mounted hole 31,
The upper surfaces of both casings are screwed together. Further, the nuts are screwed into the mounting screws 60 penetrating the through holes of the side edge side mounting member 50 and the mounted holes 51, so that the side surfaces of both casings are screwed together. The lower edge side attachment member 40 hooks the hook portion at the tip thereof to the lower edge portion of the casing, so that the other attachment member 3
The casings are attached to each other in cooperation with 0 and 50.

FIG. 6 to FIG. 8 show the process of connecting the casings to each other in the casing Vc of the heat exchange unit VU1.
And the casing Cc of the electrostatic precipitator unit CU are connected to each other as an example. First, as shown in FIG. 6, both casings Vc and Cc are placed on the ceiling surface or the like, and as shown in FIG. 7, the right casing Cc is lifted and brought close to the left casing Vc. In this state, the height of the right casing Cc allows the upper edge side mounting member 30 of the left side casing Vc to enter, and the lower edge side mounting member 4 of the right casing Cc.
It is at a height that allows 0 to enter the left casing Vc. Then, by lowering the left casing Cc until it comes into contact with the ceiling surface while bringing the right casing Cc close to the left casing Vc, the through hole of the upper edge side mounting member 30 of the left casing Vc becomes smaller than that of the right casing Cc. It is aligned with the mounting hole 31. Further, the lower edge side mounting member 40 of the casing Cc on the right side
Is engaged with the lower edge of the left casing Vc. Further, the through hole of the side edge side attachment member 50 of the left casing Vc is aligned with the attached hole 51 of the right casing Cc, and is screwed.

Referring to FIG. 9, the upper edge side mounting member 30 and the mounting hole 31 regulate the order in which the units are combined, and eliminate unfavorable combinations from the free combinations of the units. The positions are offset from each other so that The distance between the pair of upper edge side mounting members 30 is set to the pitch b or c, and the pair of mounting holes 3
As the distance between 0s, two types are provided: one that is compatible only with the pitch b and one that is compatible with both the pitch b and the pitch c. In the former case, each of the pair of attached holes 30 is formed by a circular hole, and in the latter case, one of the pair of attached holes 30 is (b-
It has a long hole longer than c).

In FIG. 9, the matching relationship of the combination order of each unit is shown by a solid line arrow, and the non-matching relationship is shown by a broken line arrow. As shown in FIG. 9, while the distance between the upper edge side attachment members 30 of the humidifier unit HU is the pitch c, the distance between the pair of attachment holes 31 of the electrostatic precipitator unit CU and the deodorizer unit DU is small. The distance is set only to the pitch b, so that the humidifier unit HU can be used as the electrostatic precipitator unit CU or the deodorizer unit DU.
It is prevented from being arranged on the upstream side in the air blowing direction. This is because if the humidifier unit HU is arranged on the upstream side, humidified and moist air will flow in the electrostatic precipitator unit CU and the deodorizer unit DU, resulting in loss of electrical insulation. This is to prevent the occurrence of a failure such as a breakage, which is a concern. On the other hand, the humidifier unit HU and the blower unit FU have one attached hole 31 as a long hole so that they can be arranged on the downstream side in the blowing direction of any other unit. Further, the deodorizer unit DU is regulated so as not to be arranged on the upstream side of the electrostatic precipitator unit CU.

According to this embodiment, it is possible to realize an air conditioner in which only desired units are freely combined with the basic unit VU, and the adaptability to the installation conditions can be improved. Moreover, since the casings of the units are connected by the mounting members 30, 40, 50 instead of connecting the units by ducts as in the conventional case, the entire air conditioner can be downsized. .

Further, since the upper edge side mounting member 30 and the mounting hole 31 are displaced from each other, the order in which the units are combined can be regulated, and it is not preferable in terms of function from the free combination of the units. Combinations can be eliminated. Further, since the indoor air circulation air passage 17 is provided in the air conditioner body A independently of the air supply side air passage 15 and the exhaust air side air passage 16, the balance between the air supply amount and the exhaust amount is set to a predetermined value. It is easy to hold, and it is also possible to connect the air supply side air passage 15 directly to the air conditioner for cooling and heating via a duct.

Moreover, since the indoor air circulation air passage 17 is provided in the portion where the passage width of the air supply side air passage 15 is narrowed, the entire air conditioner can be downsized. In addition, the suction port 10a of the indoor air circulation air passage 17 is connected to the intake air passage 15
Since it faces the diaphragm partition plate 70 for squeezing
The indoor air introduced from the suction port 10a into the indoor air circulation air passage 17 along a direction orthogonal to the air supply ventilation direction is guided by the diaphragm partition plate 70 in a direction parallel to the air supply ventilation direction. To be done. Therefore, the diaphragm partitioning plate 70 for narrowing the air supply side air passage 15 can also have a function of smoothly changing the direction of the flow in the indoor air circulation air passage 17, thus simplifying the structure. Can be planned.

It is displayed as an alternative, and the desired ventilation mode can be set.

Further, in the mode display portion R2, the dust collection R1b
Corresponding to the function, the mode of ON R2c for executing the dust collecting function and OFF R2d for stopping the dust collecting function are displayed.
Then, by pressing the mode setting switch S2 in a state where the dust collecting R1b function is selected by the function selection switch S1, the underline symbol T is alternately displayed at the position along the lower end of the display of the on R2c or the off R2d. As a result, it is possible to set the mode in which the dust collecting function is activated or not. Further, in the mode display portion R2, the input R2f and R2f are similarly provided corresponding to the functions of the humidifying R1c and the deodorizing R1d.

Since it can be set with, operability is good. Further, each of the functions R1a to R1d is selectively selected by the function selection switch S1 including a feed switch, and the selected function R
Since the modes R2a to R2i of 1a to R1d are set by the mode setting switch S2 including a feed switch, the setting can be performed with a small number of switch operations, resulting in better operability. Furthermore, since the mode of executing or stopping the function is excluded from the modes R2a to R2c of the ventilation function R1a, the ventilation function R1a does not stop even if the switches S1 and S2 are operated by mistake. . Therefore, the carbon monoxide concentration in the room does not rise due to an erroneous operation.
