Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a refrigeration system that is integrally configured with refrigeration cycle equipment, and particularly relates to an improvement of a control panel for controlling the operation of the refrigeration cycle equipment.

[Conventional technology]

As this type of refrigeration system, one having a configuration as schematically shown in FIG. 5 has been proposed. To explain this simply, the reference numeral 1 in the figure is the main body of the water cooling device, and this main body 1 is composed of a machine room part 2 located at the lower part and a heat exchanger part 3 located at the upper part. . The machine room section 2 is constructed by arranging a compressor 25 and a non-use side condenser 10 in parallel in a space formed by columns 13 erected from the four corners of the underframe 4, and further includes A usage-side water cooler 17 serving as the heat exchanger portion 3 is placed and fixed on the upper end side of the heat exchanger portion 13 . The main body 1 in which these refrigeration cycle devices are installed is surrounded by left and right side panels 11, 11, and a front panel 2.
3, 24, a rear panel (not shown), a top panel 22, and other exterior panels, and the entire structure is configured as a sealed structure.

By the way, in the case of the above-mentioned refrigeration system, there are various control parts for controlling the operation of various refrigeration cycle devices arranged in the main body 1, switches for remote control, indicator lights, etc. There is a need for a centralized arrangement of electrical components as a control section. Conventionally, among these types of electrical components, control components 191a (first electrical component group) that are not frequently manually operated, such as power terminal blocks, relays, etc., are used as the control panel 19 in the main body 1.
It is installed inside the upper front part of the machine room, and
Switches 191b (second electrical parts group), such as operation switches, temperature controllers, and indicator lights, which require manual operation from the outside and are frequently operated, are as follows:
Generally, the operation box 192 is fixedly provided on the outer wall of the right panel 11, and these are connected by electrical wiring or the like. In other words, among the electrical components that make up the control unit as described above, frequently used switches for controlling the operation of the refrigeration equipment are exposed on the panel surface so that they can be easily operated from the outside. However, the wiring and the like inside the refrigeration apparatus such as the compressor are not used frequently and are preferably provided by being incorporated into the main body 1.

[Problem that the invention attempts to solve]

However, according to the conventional configuration as described above, the control panel 19 to which the control parts 191a are attached and the operation box 192 to which the switches 191b are attached are separated, and the electrical wiring for connecting them is After the assembly of the machine room section 2 and the heat exchanger section 3 constituting the main body 1 is completed, the right side panel 11 must be assembled to the support column 13 side, and the complexity cannot be avoided. This was a major problem in terms of ease of assembly. In particular, with such a configuration, it is necessary to perform the electrical wiring inside and outside the main body 1 separately and separately, and then to perform the troublesome and complicated work of connecting these wires. It was hot. In addition, in such a configuration, since the switches 191b are attached to the outer wall of the right panel 11, an electric box (operation box 19) is installed to prevent electric shock for electrical safety.
2) It had to be stored inside, which led to problems such as increased costs. Furthermore, since the operation box 192 is provided protruding from the side of the main body 1, the volume when packing this type of device main body 1 becomes too large.
There are also problems such as the need to be careful during transportation, and it is desired to take some measures that can eliminate these problems.

[Means for solving problems]

The refrigeration system according to the present invention is equipped with a control panel that accommodates and arranges electrical components for controlling the operation of refrigeration cycle equipment, and a device mounting plate constituting the control panel is bent to form recesses and protrusions. Electrical components that are tall and require less manual operation are installed in the recesses, and electrical components that are shorter and require more manual operations are installed in the convex locations, and openings are provided in the panel corresponding to the convex locations. It is designed to provide a.

According to the present invention, electrical components such as control parts for controlling the operation of various refrigeration cycle equipment required for refrigeration equipment, switches for remote control, indicator lights, etc. are installed in the main body. It can be appropriately and reliably housed and disposed within a panel, electrical wiring for connecting these electrical components can be easily performed, and there is no problem in terms of operability.

As is well known, in a refrigeration system having such a configuration, the high-temperature, high-pressure gas refrigerant discharged from the compressor 25 enters the refrigerant pipe of the non-use side condenser 10, exchanges heat with the cooling water, and then returns to the high-pressure state. becomes a liquid refrigerant,
Further, by passing through a throttling device (not shown), the refrigerant becomes a low-pressure liquid/gas mixture and enters the user-side water cooler 17. After exchanging heat with water, it becomes a gas refrigerant and returns to the compressor 25. A refrigeration cycle is formed, and this operation is repeated thereafter, but the noise generated from the compressor 25 is removed from the non-use side condenser 1.
0. Since the usage-side water cooler 17 is formed as a part of the sound insulation wall, the sound is attenuated together with the sound insulation of the front panels 23 and 24, and low external noise can be provided.

[Effect of idea]

As explained above, according to the present invention, the equipment mounting plate for mounting electrical components that control the operation of refrigeration cycle equipment, etc. is bent to form recesses and protrusions. The control panel is constructed by attaching electrical components that are operated less frequently, and electrical components that are shorter and more frequently operated manually in convex locations, so electrical components of different heights can be placed neatly, easily, and reliably within the main body. It is excellent in terms of ease of assembly. Further, since openings are provided in the panel corresponding to the convex portions, electrical components that are frequently manually operated are brought close to the openings and can be easily operated.
