Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement in a panel device for a refrigeration system, and particularly to an improvement in the mounting structure of an upper front panel that closes the front upper part.

[Conventional technology]

Figures 6 and 7 are diagrams showing the mounting structure of the front panel in a conventional refrigeration system. A screw hole is fixed to the lower flange portion 30a through a through hole in the lower front panel 31 (see 22 in FIG. A through hole 32a is provided. 3
1 is the lower front panel made of relatively thin steel plate,
The upper end flange portion 31a is provided with a through hole opposite to the screw hole 32a of the frame 32 described above. Further, at the lower end of the lower front panel 31, a through hole is provided for insertion into a protrusion provided on an unillustrated underframe (see 4 in FIG. 2). Note that 32b is a nut serving as a female thread.

In the above configuration, the conventional front panel mounting structure of the refrigeration equipment involves first inserting the upper front panel 30 into a groove on the top panel side, and attaching the upper front panel 30 to the upper front panel 30 through the through hole provided in the top panel. Temporarily fix it with screws. Next, after placing the lower front panel 31 on the underframe, it is placed in contact with the frame 32 together with the upper front panel 30, which is fixed in advance opposite to the screw holes provided in the frame 32, through the through hole. Install and fix. At this time, the upper front panel 30 and the lower front panel 31 are attached and fixed with the horizontal and vertical degrees aligned. After the lower front panel 31 has been attached and fixed, the upper front panel 30, which has been temporarily fixed in advance, is fixed by further tightening the screws.

[Problem that the invention attempts to solve]

In the conventional panel device as described above, it is necessary to temporarily fix the upper front panel 30 to the top panel side in advance, and the positioning with the lower front panel 31 is not done, so adjustment to maintain horizontal and verticality is required. In practice, this was a major problem in assemblability, such as the need for time-consuming adjustments.
Further, after the lower front panel 31 is fixed, the upper front panel 30 needs to be retightened, resulting in higher costs.

[Means for solving problems]

In order to solve such problems, the panel device for the refrigeration equipment according to this invention is provided with a cut-and-raised piece that protrudes toward the rear side at the lower end of the upper front panel, and a reinforcing member is provided opposite to this cut-and-raised piece. A notch is formed at the upper end for positioning and locking during temporary fixing,
Further, a female threaded portion for screwing is provided on the reinforcing member side opposite to the notch formed on the upper front panel side by the cut-and-raised piece.

[Effect]

According to the present invention, the upper end of the upper front panel is inserted into the gap on the top panel side, and the cut and raised piece at the lower end is engaged with the notch on the reinforcing member side to hold and temporarily fix the upper front panel in position. The upper front panel can be attached and fixed to the reinforcing member by screwing the lower end to the female threaded portion using the notch formed by the cut and raised piece.

Furthermore, in the above-mentioned refrigeration system, the compressor 25
As is clear from FIG. 5, the high-temperature, high-pressure gas refrigerant discharged from the refrigerant enters the refrigerant pipe of the non-use side condenser 10, exchanges heat with the cooling water, and then becomes a high-pressure liquid refrigerant. By passing through the expansion device 27, the refrigerant becomes a low-pressure liquid/gas mixture, enters the user-side water cooler 17, exchanges heat with the cold water, and then becomes a gas refrigerant and returns to the compressor 25, thereby starting the refrigeration cycle. is formed, and this operation is repeated thereafter. In this case, the noise generated from the compressor 25 is absorbed by the front panel 2, since the non-use side condenser 10 and the use side water cooler 17 are formed as part of the sound insulation wall.
Together with the sound insulation of 3 and 24, it is attenuated and can provide low noise to the outside.

In the above embodiment, the water-cooled condenser 10 is provided on the non-use side and the water cooler 17 is provided on the use side, but the arrangement may be reversed depending on the purpose of use. Place the container 17 on the underframe 4,
The water-cooled condenser 10 may be installed at the top of the main body.

[Effect of idea]

As described above, in this invention, when attaching the upper and lower front panels, the upper end of the upper front panel is inserted into the gap between the flanges of the side panels and the top panel, while the lower end is attached to the cut-out piece of the support column. Since the reinforcing member is latched to the notch at the upper end, the upper front panel can be positioned and held in the latched state and temporarily fixed.This allows the lower front panel to be applied to the underframe and the reinforcing member. In some cases, the worker does not have to hold the upper front panel in that position and can work alone, and it is also possible to do the screwing work of the upper and lower panels at the same time, improving work efficiency. The notch formed by the cut-and-raised piece can be used as a hole for inserting the mounting screw for fixing the upper front panel, which eliminates the need for a separate hole, and has various practical effects such as simplifying the manufacture of the upper front panel. be.
