2. Description of the Related Art As an apparatus provided with a refrigerator, a refrigeration circuit component has a main configuration of the apparatus, such as various air conditioners and various cooling apparatuses, and for example, supplies dry compressed air to an air apparatus. Such as a compressed air supply device for air conditioning, the components such as an air compressor and air tank are integrated with a compressed air dehumidifier that cools and dehumidifies compressed air with a refrigerator, and a refrigerator unit is installed in part of the device. There are types that are. In both types of devices,
When assembling a refrigerator, it is a general method to assemble the refrigerator while fixing it with a screw or the like on a mounting board made of a steel plate.

For example, taking a compressed air dehumidifier as an example,
As shown in the assembly system diagram in FIG. 5, the compressed air dehumidifier 120 includes a refrigerant compressor 121, a refrigerant condenser 122, a refrigerant decompressor 124, a refrigeration circuit component such as the condenser fan 123, and a refrigerant of the refrigeration circuit. A heat exchanger 125 for compressed air cooling and dehumidification incorporating an evaporator is provided. Along with a large number of connecting parts for connecting and integrating the heat exchangers 125, the heat exchanger 125 is fixed to a mounting board 127 provided at the bottom of the case, so that compressed air dehumidification is achieved. The device is assembled.

[0004] This assembling work involves assembling the support frame 131 of the fan 123 and the condenser 122, attaching the support legs 132 of the heat exchanger 125, and the like, as in the case of the compressor 121. 127 includes a work of screwing via a rubber washer or the like for vibration isolation as necessary. Further, after connecting and fixing the parts to each other by piping or wiring, suction of the heat exchanger 125 or the refrigeration circuit is performed. Parts that need to be covered with a heat insulating material in order to increase the thermal efficiency, such as side piping, which may cause dew condensation, have a heat insulating covering member 12 previously prepared according to its shape.

Embodiment 2 FIGS. 2 to 4 show another embodiment in which the mounting structure of the refrigerator component of the present invention is adapted to a compressed air dehumidifier as in the first embodiment. The package block 20 is made of a plastic foam that can be used as a structural material, such as an impact-resistant polystyrene foam or a polypropylene foam. The package block body 20 forms a flat rectangular parallelepiped in the horizontal direction (the horizontal direction in FIG. 2), and can be divided in the horizontal direction into a pair of substantially symmetric left and right block bodies 20a and 20b.

Each of the block members 20a and 20b includes a heat exchanger 125 for cooling and dehumidifying compressed air as a component which may be subjected to dew condensation and needs heat insulation coating processing among components constituting the compressed air dehumidifier. And an accumulator 126 interposed between the refrigerant evaporator and the compressor 121 housed in the heat exchanger, and a housing recess 21 for housing a pipe connecting them and the like. . The storage recesses 21 respectively provided at the corresponding positions of the left and right block bodies are overlapped by the dowel 29a and the dowel hole 29b used for overlapping the left and right block bodies 20a and 20b. When assembling, the parts 125 and 124 and the piping thereof form a storage space to be wrapped and stored in the package block body.

Reference numeral 22a denotes a recess into which the one end 122a of the condenser 122 is to be fitted. The recess 22a is slightly recessed in the thickness direction of the left block body 20a and does not penetrate. On the other hand, the recess 2
An opening 23 provided below 2a is an intake port. The right block body 20b is also provided with a similar intake port at a position corresponding to the intake port 23 to form the intake port 23 as shown in FIG. 3, but faces the concave portion 22a at the upper portion thereof. The portion is a through opening 22b (FIG. 3),
The condenser 122 forms a support recess 25 into which the condenser 122 is fitted.

Using such a package block body 20, a component requiring heat insulation coating is housed and fixed in the package block body. Further, the package block body is made of the same material and the same size plate as the package block body. Support recess 25
Similarly, a panel frame 27 having a support concave portion (not shown) is erected at both ends of the mounting substrate 30 at positions facing the surface, and both ends of the condenser 122 are supported by being sandwiched by the support concave portions 25. Then, the intake fan 32 is fixed on the substrate, and its exhaust duct is opened to the exhaust port 23. The method of standing the package block and the panel frame 27 on the substrate 30 can be performed in the same manner as in the first embodiment. When the assembled product is stored in a cabinet, the assembly is completed. For fixing the condenser 122, the fan 1
The condenser 23 and the condenser 122 may be formed as a single unit. In this case, a leg may be suspended from the condenser 122 and a fan 123 may be attached to the leg and supported.

According to the present invention, the component can be supported and fixed only by placing or inserting the component in the storage recess, so that the assembling time can be reduced. The package block, which can be divided vertically or horizontally, can be assembled with a simple fixing tool such as a fixing band or adhesive tape, if necessary, by aligning the positioning part consisting of a dowel or a dowel hole and a part for preventing displacement. Fixation is completed. At the same time, these parts
Since it is wrapped or supported by the plastic foam, it can sufficiently withstand impact and shaking, and can be easily transported.

Furthermore, the package block body absorbs vibration, exhibits a heat insulating effect (condensation prevention effect) and a soundproof effect, and improves energy efficiency by improving heat insulation. or,
The number of parts fixing members is also small, and the parts requiring heat insulation coating and anti-vibration treatment are stored in a package block in advance to make a unit, which greatly improves the efficiency of assembly work and reduces product costs. Is achieved. Also, since the package block body directly performs vibration prevention processing on parts that generate noise and vibration, it is much more effective than the vibration-proof coating processing applied to the refrigerator case having many openings, Also, the amount of sound absorbing material used can be reduced, and the soundproofing and anti-vibration functions are improved, so that the driving sound becomes quieter.
