Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a casing structure of an outdoor air conditioner.

[0002]

[Prior art]

 Large-scale air conditioners and outdoor units of direct expansion type air conditioners that are separated into indoor and outdoor units are housed and installed in casings to protect their components from wind and rain. The casing is provided with a maintenance lid or the outer panel itself can be removed. This allows maintenance and electrical wiring of the internal air conditioner to be performed in the installed state.

[0003]

[Problems to be solved by the invention]

 However, when installing an air conditioner housed in a casing as described above, it is necessary to open the maintenance lid or remove the outer plate to provide space for work. In many cases, there is not always enough working space. Most of the maintenance targets are control equipment and switchboards made of strictly prohibited electrical and electronic components such as rain and dew.However, when the maintenance cover is opened or the outer plate is removed, the control equipment is It is difficult to work in wind and rainy weather. Therefore, there is a problem that maintenance and inspection work cannot be performed immediately when necessary.

[0004] Furthermore, since the work is performed outdoors, it is necessary to separately install lighting equipment and the like at night, which requires a lot of man-hours. Therefore, in view of the above problems, the present invention provides a casing structure for an air conditioner that ensures a secure working space and enables safe and easy maintenance and electrical wiring work without being affected by the weather. With the goal.

[0005]

[Means for Solving the Problems]

 For this reason, the present invention provides a casing structure of an air conditioner that houses an air conditioner and is installed outdoors, and includes a first room in which the air conditioner is arranged, and a first room and a partition wall. It consisted of a second room sandwiched between them, in which the maintenance target devices such as air conditioner control equipment were installed, and an opening / closing panel that could be accessed from the outside was provided in the second room. . As a result, the second room is secured as a work space, and since the control devices and the like are not exposed to the outside, maintenance work can be performed without being affected by the weather.

[0006] By providing the open / close panel on a plurality of surfaces of the second room, even when the adjacent open / close panel is in contact with another adjacent equipment depending on the installation condition, the other open / close panel is opened to enter the maintenance room. And easily access switchboards and control equipment. Furthermore, by providing a lighting device in the second room, it is not necessary to prepare and install a lighting device each time the work is performed, and the work can be easily performed at any time regardless of night and day.

[0007]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to examples. FIG. 1 is an external front view showing a configuration of an embodiment in which an outdoor unit is housed inside, FIG. 2 is a top view thereof, and FIG. 3 is a sectional view showing an internal arrangement. The casing 10 includes, for example, a heat source room 11 and a maintenance room 12 in which a box having a height of about 2 m is partitioned by a partition wall 13. A refrigerator compressor 21, a heat exchanger 22, a fan 23, and the like, which constitute an outdoor unit, are installed in the heat source unit room 11, and a grill 16 is provided at an air inlet / outlet of an upper wall 14 of the heat source unit room 11. I have. The partition wall 13 does not need to be a strictly closed wall, and may be any wall that can secure a maintenance room as a space necessary for maintenance work and the like.

The maintenance room 12 is provided with opening and closing panels 17, 18, and 19 of a size that allows an operator to easily enter and leave the three surfaces, and an illuminator 30 is provided on the upper wall 15 of the ceiling. I have. FIG. 1 shows a state in which each open / close panel is closed, and FIG. 2 shows a state in which the open / close panel is slightly opened. Further, on the inner wall of each of the maintenance rooms 12 near the respective open / close panels, lighting switches 31, 32, 33 for the lighting device 30 are provided.

In the maintenance room 12, the partition wall 13 includes a control device 25 and a switchboard 26 electrically connected to a temperature sensor, a humidity sensor, a pressure sensor, and the like (not shown) of the heat source unit room 11, a control valve for a refrigerant pipe, and the like. Is installed.

The embodiment is configured as described above. Since the switchboard 26 and the control device 25 are disposed in the maintenance room 12 and are not exposed to the outside, maintenance work for the switchboard and the control device can be easily performed even in bad weather such as wind and rain. Can be performed. Moreover, since the illuminator 30 is installed in the maintenance room 12, it is not necessary to prepare and install the illuminator every time the work is performed, and the work can be easily performed at any time regardless of the time zone.

Further, since a space required for maintenance work and the like is formed integrally with the heat source unit room 11 as the maintenance room 12, there is no inconvenience that a work space cannot be taken after installation.

Further, the open / close panels 17, 18 and 19 are provided on three surfaces of the maintenance room 12, and the user can enter the maintenance room 12 by opening any of the open / close panels. Even when the surface is in contact with another adjacent equipment, it is possible to easily access the switchboard 26, the control device 25, and the like. At this time, since the lighting switches 31, 32, and 33 are provided near the open / close panels 17, 18, and 19, it is not necessary to search for the lighting switch after entering the maintenance room 12.

In the embodiment, an example in which the outdoor unit is housed in the casing has been described. However, the present invention is not limited to this, and the entire air conditioner in which the indoor unit and the outdoor unit are integrated may be housed. In addition, the lighting switch is provided near each opening / closing panel, but may be provided, for example, on the inner wall of the opening / closing panel.

[0014]

[Effect of the invention]

 As described above, according to the present invention, the casing of the air conditioner installed outdoors has the first room in which the air conditioner is arranged, and the second room formed by sandwiching the partition wall with the first room. In addition to installing maintenance equipment such as air conditioner control equipment in the second room and providing an open / close panel that allows access from the outside, the second room is secured as a work space. In addition, since control devices and the like are not exposed to the outside, there is an effect that maintenance work can be performed without being affected by the weather.

[0015] In addition, by providing the open / close panel on a plurality of surfaces of the second room, the maintenance room can be entered from any of the open / close panels even when adjacent to other equipment, so that the control device and the switchboard can be easily provided. Can be accessed. Furthermore, by providing a lighting device in the second room, there is no need to prepare and install a lighting device each time work is performed, and work can be easily performed at any time regardless of night and day.
