Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a housing structure for an air conditioner.

Generally, as a means to purify the air in offices, hospitals, etc. and adjust the temperature and humidity, cold water sent out from a refrigerator or hot water from a boiler is used to cool or warm the air sucked in through a heat exchanger.
Furthermore, an air conditioner is used that adjusts the humidity and sends out the air as necessary. An example is shown in FIG.

The air conditioner 1 includes a ventilation chamber 2 that houses a ventilation fan 3 and a housing 4 that forms a heat exchange chamber 5, and the ventilation chamber 2 is surrounded by a heat insulating member that has heat insulation and sound absorption effects. The heat exchange chamber 5 houses a heat exchanger 6, a humidifier 7, an eliminator 8, and the like. In the figure, 9 is an air intake port, 10 is an exhaust port, 11
12 is a cold/hot water supply pipe, 12 is its discharge pipe, and 13 is a steam or water supply pipe to the humidifier 7.

The housing 4 consists of a framed skeleton 14 and a wall 15 attached to the skeleton 14.
5 is removably fixed to the outside of the frame 14 for inspection and taking out/taking out the heat exchanger etc. housed therein.
FIG. 2 shows how to attach the wall 15 to the corner frame 14a.

The corner frame 14a is made of angle material,
The wall body 15 has a heat insulating member 17 attached to the inside of a side plate 16 made of a steel plate or the like, and the four circumferences of the side plate 16 are bent inward to surround the heat insulating member 17. This wall body 15 is attached to each side of the frame 14 with bolts 19 via rubber gaskets 18 to maintain airtightness.

In this case, when the heat exchange chamber 5 is cooled, there is a risk that dew condensation may form on the surface of the skeleton 14a whose inner surface is in contact with the heat exchange chamber 5 when there is a large temperature difference between the inside and outside. Therefore, it is conceivable to attach the heat insulating material 20 to the inner surface of the skeleton 14a, but this would be extremely difficult.

The present invention has been made in view of these points, and provides a novel casing structure that prevents dew condensation from forming on the skeleton even when there is a temperature difference inside and outside the casing, and that simplifies the structure of the wall. The purpose is to provide.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIGS. 3 to 6 relate to embodiments of the present invention, in which an air conditioner 30 is equipped with a ventilation chamber 31 and a casing 32 forming a heat exchange chamber 33, as in the previous example.
The wall body 35 is detachably attached to a frame 34. The framework 34 includes an upper skeleton 36 and a lower skeleton 37.
and a corner frame 38, each of which is formed by bending an angle member or a band steel plate into an L shape, and an appropriate number of band-shaped reinforcing plates 39 are attached between the upper and lower frames 36, 37 as necessary.

The wall body 35 has a flat side plate 40 as shown in FIG.
A heat insulating member 41 is attached to the inside of the housing, and during assembly, a notch 42 is formed by cutting out the heat insulating member 41 on one side located at the corner of the housing. This notch 42
The width a is approximately equal to the thickness of the heat insulating member 41, or is cut out to be slightly shorter.

Next, the procedure for assembling the casing 32 will be explained.
First, the upper skeleton 36, the lower skeleton 37,
A frame 34 is formed by the corner skeleton 38 and the reinforcing plate 39. Next, the wall body 35 is pressed against each skeleton from the inside, with the heat insulating member 41 facing inside. At this time, the notches 42 are abutted against the corner frame 38 as shown in FIG. 5, and are fixed with bolts 43 located inside the corner frame 38. Adjacent wall bodies 35 are tightly attached to the skeletons 36, 37 and the reinforcing plate 39 other than the corners to prevent the skeleton and the reinforcing plate from being exposed inward. As a result, the air conditioner 3 shown in FIG.
0 is formed. In the drawings, parts that are the same as those in the conventional example are designated by the same reference numerals, and explanations thereof will be omitted.

As described above, in the present invention, the wall made of a flat side plate lined with a heat insulating member is attached to the inside of the skeleton, so the skeleton is not exposed to the internal heat exchange chamber. There is no risk of condensation forming on the skeleton even when there is a large temperature difference inside and outside the casing.
In addition, since the side plates are shaped like flat plates, they have the advantage of being easy to process and can be provided at low cost.
