[0033] The frame 3 is a substantially rectangular parallelepiped component that constitutes the outer shell of the outdoor unit 2 and forms a space S inside. The control box 7 is a component that accommodates electrical components such as an inverter that controls the compressor 4, etc. The fixing component 10 is a component that is arranged adjacent to the compressor 4 and fixes the refrigerant piping 9 to the frame 3. The various components that constitute the outdoor unit 2 are arranged in the space S.

[0034] The frame 3 includes an upper panel 3a defining the upper side of the space S, a bottom panel 3b defining the lower side of the space S, a front panel 3c defining the front side (end face in one direction) of the space S, a rear panel 3d defining the rear side of the space S, a right side panel 3e defining the right side of the space S, and a left side panel 3f defining the left side of the space S. The frame 3 includes a partition 3g that separates a heat exchanger chamber S1 in which an outdoor heat exchanger 5 and the like are arranged and a machine chamber S2 in which a compressor 4, a control box 7 and the like are arranged.

[0035] The compressor 4 is a device that is housed in the machine room S2 of the space S and is disposed at a position facing the front panel 3c. The compressor 4 compresses the refrigerant circulating in the refrigerant cycle and discharges it to the refrigerant pipe. Figure 1 In FIG. 1 , other components arranged adjacent to the compressor 4 in the machine chamber S2 are omitted. Figure 2 In the figure, some devices arranged in the machine room S2 are omitted.

[0036] A part or the whole of the front panel 3c is configured to be openable and closable. The front panel 3c is formed with an exhaust opening (not shown) for exhausting the external air introduced into the outdoor unit 2 by the blower 6. The rear panel 3d is formed with an intake opening (not shown) for introducing the external air into the outdoor unit 2.

[0037] The partition 3g is a component formed in a substantially L-shape when viewed from above, and includes a first partition 3ga extending from the inner surface of the front panel 3c toward the outdoor heat exchanger 5 and a second partition 3gb extending from the end of the first partition 3ga on the outdoor heat exchanger 5 side toward the left side panel 3f.

[0038] The heat exchanger chamber S1 has a space that is substantially L-shaped when viewed from above. In the heat exchanger chamber S1, the outdoor heat exchanger 5 that is substantially L-shaped when viewed from above is placed on the bottom panel 3b along the right side panel 3e and the rear panel 3d. A blower 6 that guides external air to the outdoor heat exchanger 5 and a motor 6a that drives the blower 6 are arranged in the heat exchanger chamber S1.

[0039] The machine room S2 is a space divided by the front panel 3c, the left side panel 3f and the partition 3g. In the machine room S2, the compressor 4 is placed on the bottom panel 3b. A support portion 8 supported by the first partition 3ga is provided at the upper part of the machine room S2. The control box 7 is supported by the support portion 8 by being suspended.

[0040] The refrigerant pipe 9 is a pipe for circulating the refrigerant circulating in the refrigerant cycle. The refrigerant pipe 9 is a general term for the pipes provided in the machine room S2 of the outdoor unit 2. Figure 1 and Figure 2 The refrigerant pipe 9 connecting the compressor 4 and the muffler 14 is shown, but illustration of other refrigerant pipes is omitted.

[0041] The fixing member 10 is a member for fixing the refrigerant pipe 9 to the frame 3. Figure 3 As shown, one end of the fixing member 10 is fixed to the frame 3 by a fastening bolt 10a. Figure 1 As shown, the other end of the fixing member 10 extends to the bottom panel 3b along the height direction HD, and is fixed to the bottom panel 3b by a fastening bolt (not shown).

[0042] The main accumulator 11 and the sub-accumulator 12 are devices for separating the refrigerant supplied to the compressor 4 into gas and liquid. Figure 2 and Figure 3 As shown, the main accumulator 11 is disposed between the compressor 4 and the first partition plate 3ga when the outdoor unit 2 is viewed from above. The sub-accumulator 12 is disposed between the compressor 4 and the second partition plate 3gb when the outdoor unit 2 is viewed from above.

[0043] The silencers 13 and 14 are devices for reducing the noise caused by the refrigerant flowing through the refrigerant pipe 9. Figure 2 and Figure 3 As shown in FIG. 1 , the muffler 13 is disposed between the compressor 4 and the left side panel 3f when the outdoor unit 2 is viewed from above. The muffler 13 is disposed between the compressor 4 and the first partition plate 3ga when the outdoor unit 2 is viewed from above.

[0044] like Figure 2 and Figure 3 As shown, the machine room S2 is provided with a compressor 4, a main accumulator 11, a sub-accumulator 12, and mufflers 13 and 14. These devices arranged in the machine room S2 and through which the refrigerant flows are collectively referred to as a refrigeration device 20. The devices constituting the refrigeration device 20 are connected via a refrigerant pipe 9.

[0045] The partition plate 3g is mounted on the frame 3 by fastening bolts (not shown). Figure 2 and Figure 3As shown, the partition plate 3g is provided with a gap CL1 between the partition plate 3g and the main accumulator 11 constituting the refrigeration device 20 in the horizontal direction parallel to the installation surface Su and is arranged adjacent to the main accumulator 11. Furthermore, the partition plate 3g is provided with a gap CL2 between the partition plate 3g and the muffler 14 constituting the refrigeration device 20 in the horizontal direction and is arranged adjacent to the muffler 14. Furthermore, the partition plate 3g is provided with a gap CL3 between the partition plate 3g and the refrigerant pipe 9 constituting the refrigeration device 20 in the horizontal direction and is arranged adjacent to the refrigerant pipe 9.

[0046] The fixing member 10 is mounted on the frame 3 by means of a fastening bolt 10a. Figure 2 and Figure 3 As shown, the fixing member 10 is disposed adjacent to the main accumulator 11 with a gap CL4 provided between the fixing member 10 and the main accumulator 11 constituting the refrigeration device 20 in a horizontal direction parallel to the installation surface Su.

[0047] Furthermore, the fixing member 10 is disposed adjacent to the compressor 4 with a gap CL5 provided between the fixing member 10 and the compressor 4 constituting the refrigeration device 20 in the horizontal direction.

[0048] The muffler 13 is mounted on the frame 3 via the refrigerant pipe 9 and the fixing member 10. Figure 2 and Figure 3 As shown, the silencer 13 is arranged adjacent to the compressor 4 with a gap CL6 provided between the silencer 13 and the compressor 4 in the horizontal direction.

[0049] In this embodiment, in order to prevent the refrigeration equipment 20 disposed in the machine room S2 from being displaced due to severe vibration or impact during transportation, thereby causing stress in the refrigeration equipment 20 or the refrigerant piping 9 connected to the refrigeration equipment 20 and causing damage, the first vibration-proof component 100 and the second vibration-proof component 200 are installed in the refrigeration equipment 20. The first vibration-proof component 100 is installed in the refrigeration equipment 20 in a manner covering the entire circumference of the side surface of the compressor 4 along the circumferential direction CD. The second vibration-proof component 200 is installed in the refrigeration equipment 20 to fill at least the gaps CL1, CL2, CL3, CL4, CL5, and CL6.

[0050] Next, the first vibration isolating member 100 , the second vibration isolating member 200 , and the third vibration isolating member 300 attached to the refrigeration device 20 of the present embodiment will be described with reference to the drawings. Figure 4 is along Figure 1 The cross-sectional view of the outdoor unit 2 taken along the arrow direction AA shows a state where the vibration-isolating members (the first vibration-isolating member 100 , the second vibration-isolating member 200 , and the third vibration-isolating member 300 ) are not mounted. Figure 5 is along Figure 1 The cross-sectional view of the outdoor unit taken along the AA arrow direction shows a state where the first vibration isolating member 100 is mounted.

[0051] When installing the first vibration-proof component 100, the second vibration-proof component 200, and the third vibration-proof component 300 in the refrigeration equipment 20 of this embodiment, the following steps are performed. Figure 4 The first vibration-isolating member 100 is installed in the region from the lower end to the upper end in the height direction of the refrigeration equipment 20 in a manner that covers the entire circumference of the compressor 4 and the main accumulator 11 in the state shown (first installation step). As a result, the first vibration-isolating member 100 is in contact with at least a portion of the side surface of the compressor 4 and the main accumulator 11. In this step, the first vibration-isolating member 100 is installed in a state where it does not contact the partition plate 3g and the fixing member 10.

[0052] Second, to cover Figure 5 The second vibration isolating member 200 is mounted on at least a portion of the region from the lower end to the upper end in the height direction HD of the refrigeration equipment 20 in a manner that covers the entire circumference of the first vibration isolating member 100 in the state shown (second mounting step). As a result, the second vibration isolating member 200 is brought into contact with at least a portion of the first vibration isolating member 100.

[0053] At this time, the second vibration isolating member 200 is installed in a state of contacting both the first vibration isolating member 100 and the partition plate 3g so as to fill the gaps CL1, CL2, and CL3 together with the first vibration isolating member 100. Furthermore, the second vibration isolating member 200 is installed in a state of contacting both the first vibration isolating member 100 and the fixing member 10 so as to fill the gaps CL4 and CL5 together with the first vibration isolating member 100. Furthermore, the second vibration isolating member 200 is installed in a state of contacting both the first vibration isolating member 100 and the muffler 13 so as to fill the gap CL6 together with the first vibration isolating member 100.

[0054] Third, the third vibration-proof component 300 is arranged in a manner to seal the upper part of the compressor 4 and the main accumulator 11 covered by the first vibration-proof component 100. By arranging the third vibration-proof component 300, the compressor 4 and the main accumulator 11 are covered by the bottom panel 3b at the bottom, by the first vibration-proof component and the second vibration-proof component 200 at the side, and by the third vibration-proof component 300 at the top. The third vibration-proof component 300 is formed, for example, of felt formed into a sheet by compressing animal fibers or other fibers. By performing the above work, Figure 3 Status shown.

[0055] The first vibration-isolating member 100, the second vibration-isolating member 200, and the third vibration-isolating member 300 of the present embodiment may be installed only during the transportation of the outdoor unit 2, but may be installed not only during the transportation of the outdoor unit 2 but also during the operation after the outdoor unit 2 is installed. By installing the first vibration-isolating member 100, the second vibration-isolating member 200, and the third vibration-isolating member 300 on the refrigeration device 20 during the operation of the outdoor unit 2, the vibration or noise of the refrigeration device 20 can be appropriately suppressed.

[0056] Next, the detailed structure of the first vibration isolating member 100 will be described with reference to the drawings. Figure 6 1 is a plan view showing the first vibration isolating member 100 . Figure 7 is along Figure 6 A cross-sectional view of the first vibration-proof component 100 cut along the BB arrow direction. Figure 6 As shown in FIG. 1 , the first vibration-isolating member 100 is a strip-shaped member whose length L12 in the longitudinal direction LD is longer than the length L11 in the height direction HD. Figure 7 As shown, the first vibration isolating member 100 is formed by laminating a first inner layer 110 and a first outer layer 120. The first inner layer 110 and the first outer layer 120 are bonded to each other by, for example, an adhesive.

[0057] The first inner layer 110 is a member disposed in contact with the compressor 4 and the main accumulator 11. The first outer layer 120 is a member disposed in contact with the first inner layer 110 and the second vibration-proof member 200. Figure 7 As shown, the length of the first inner layer 110 in the longitudinal direction LD is shorter than the length of the first outer layer 120 in the longitudinal direction LD. This is to bond the first end 120a of the first outer layer 120 in the longitudinal direction LD and the second end 120b of the first outer layer 120 in the longitudinal direction LD with an adhesive or the like.

[0058] The first inner layer 110 is formed of, for example, felt formed into a sheet by compressing animal fibers or other fibers. The first outer layer 120 is formed of a material (for example, a rubber material) that exhibits high sound insulation. The first inner layer 110 may be formed of other components having lower rigidity than the rubber material. In addition, a modified example may be adopted in which the first inner layer 110 is formed of a rubber material, and the first outer layer 120 is formed of other materials having lower rigidity than the rubber material.

[0059] Figure 8 4 is a cross-sectional view showing a state where the first vibration-proof member 100 is mounted on the compressor 4 and the main accumulator 11. Figure 8 As shown, the first vibration-isolating member 100 is arranged so as to cover the compressor 4 and the main accumulator 11 along the circumferential direction CD in a state of being in contact with a part of the side surface 4a of the compressor 4 and the side surface 11a of the main accumulator 11. The first vibration-isolating member 100 is maintained in a state of covering the compressor 4 and the main accumulator 11 by bonding a first end portion 120a of the first outer layer 120 in the longitudinal direction LD and a second end portion 120b of the first outer layer 120 in the longitudinal direction LD with an adhesive or the like.

[0060] Fig. 9 1 is a front view showing a state where the first vibration-proof member 100 is mounted on the compressor 4 and the main accumulator 11. Fig. 9 As shown, the first vibration-isolating member 100 is disposed in a region from the lower end to the upper end of the compressor 4 and the main accumulator 11 in the height direction HD.

[0061] like Figure 5 As shown, the first vibration-isolating member 100 is arranged in a state where it does not contact the partition plate 3g, the fixing member 10, the refrigerant pipe 9, and the muffler 14 arranged adjacently when it is attached to the compressor 4 and the main accumulator 11. Since there is sufficient space in the gap CL1 between the main accumulator 11 and the partition plate 3g, the gap CL2 between the muffler 14 and the partition plate 3g, the gap CL3 between the refrigerant pipe 9 and the partition plate 3g, the gap CL4 between the main accumulator 11 and the fixing member 10, the gap CL5 between the compressor 4 and the fixing member 10, and the gap CL6 between the compressor 4 and the muffler 13, the first vibration-isolating member 100 can be attached to the compressor 4 and the main accumulator 11 relatively easily.

[0062] Next, the detailed structure of the second vibration isolating member 200 will be described with reference to the drawings. Fig.10 1 is a plan view showing the second vibration isolating member 200 . Fig.11 is along Fig.10 A cross-sectional view of the second vibration-proof component 200 cut along the CC arrow direction. Fig.10 As shown, the second vibration isolating member 200 is a strip-shaped member whose length L22 in the longitudinal direction LD is longer than the length L21 in the height direction HD.

[0063] like Fig.11 As shown, the second vibration isolating member 200 is formed by laminating a second inner layer 210, a second outer layer 220, and an intermediate layer 230 sandwiched between the second inner layer 210 and the second outer layer 220. The second inner layer 210 and the intermediate layer 230 and the second outer layer 220 and the intermediate layer 230 are bonded, for example, by an adhesive.

[0064] The second inner layer 210 is a member disposed in contact with the first vibration-proof member 100. The second outer layer 220 is a member disposed in contact with the second inner layer 210 and other adjacent members (for example, the partition plate 3g and the fixing member 10). Fig.11 As shown, the length of the second inner layer 210 in the longitudinal direction LD is shorter than the length L22 of the intermediate layer 230 in the longitudinal direction LD. This is to join the first end 230a of the intermediate layer 230 in the longitudinal direction LD and the second end 230b of the intermediate layer 230 in the longitudinal direction LD.

[0065] For example, a hook and loop fastener is installed at the first end 230a and the second end 230b. By joining the first end 230a and the second end 230b with the hook and loop fastener, the state where the first end 230a and the second end 230b are joined and the state where the first end 230a and the second end 230b are not joined can be appropriately switched, so that the second vibration-proof component 200 can be easily attached and detached.

[0066] The second inner layer 210 and the second outer layer 220 are formed of, for example, felt formed into a sheet by compressing animal fibers or other fibers. The middle layer 230 is formed of a material (for example, a resin material such as vinyl chloride) having higher rigidity than the second inner layer 210 and the second outer layer 220. The second inner layer 210 and the second outer layer 220 may be formed of other components having lower rigidity than the middle layer 230.

[0067] like Fig.11 As shown, the second outer layer 220 of the second vibration-isolating member 200 is composed of a first member 220a having a first thickness Th1 and a second member 220b having a second thickness Th2 thinner than the first thickness Th1. When the second outer layer 220 is not arranged in the gaps CL1, CL2, CL3, CL4, CL5, CL6, the first thickness Th1 in the first circumferential region CA1 in the circumferential direction CD surrounding the side surface of the refrigeration device 20 is different from the second thickness Th2 in the second circumferential region CA2 different from the first circumferential region CA1.

[0068] For example, the first thickness Th1 and the second thickness Th2 of the second vibration-isolating component 200 can be adjusted in a state where the second vibration-isolating component 200 is installed, so that the rigidity of the second vibration-isolating component 200 in the first circumferential area CA1 is higher than that of the second vibration-isolating component 200 in the second circumferential area CA2, and the second vibration-isolating component 200 is in a state suitable for reducing the rigidity of other adjacent components or the vibration frequency of the compressor. In addition, as the second outer layer 220 of the second vibration-isolating component 200, a modified example in which the thickness is set to be the same throughout the entire area in the circumferential direction CD can be adopted.

[0069] Fig.12 2 is a cross-sectional view showing a state where the second vibration-proofing member 200 is mounted on the refrigeration device 20 at a height where the fixing member 10 is arranged. Fig.12 As shown, the second vibration isolating member 200 is arranged to cover the entire circumference of the first vibration isolating member 100 along the circumferential direction CD while being in contact with a portion of the first vibration isolating member 100. The second vibration isolating member 200 is maintained in a state of covering the first vibration isolating member 100 by bonding the 11th end 230a of the intermediate layer 230 in the longitudinal direction LD to the 2nd end 230b of the intermediate layer 230 in the longitudinal direction LD.

[0070] like Fig.12 As shown, the second vibration isolating member 200 is arranged to fill the gaps CL1, CL2, and CL3 together with the first vibration isolating member 100 in a state of contact with both the first vibration isolating member 100 and the partition plate 3g. Furthermore, the second vibration isolating member 200 is arranged to fill the gaps CL4 and CL5 together with the first vibration isolating member 100 in a state of contact with both the first vibration isolating member 100 and the fixing member 10. Furthermore, the second vibration isolating member 200 is arranged to fill the gap CL6 together with the first vibration isolating member 100 in a state of contact with both the first vibration isolating member 100 and the muffler 13.

[0071] Fig.13 2 is a cross-sectional view showing a state where the second vibration isolating member 200 is mounted on the refrigeration device 20 at a position lower than the height at which the fixing member 10 is arranged. Fig.13 As shown, at a lower height position where the fixing member 10 is arranged, the intermediate layer 230 of the second vibration isolating member 200 is arranged so as to cover only a partial area on the front panel 3 c side of the entire circumference of the first vibration isolating member 100 .

[0072] Fig.14 2 is a front view showing a state where the second vibration-proof component 200 is installed on the refrigeration device 20. Fig.14 As shown, the second vibration-isolating member 200 is disposed in a portion of the region from the lower end to the upper end in the height direction HD of the refrigeration device 20. Fig.10 and Fig.14 As shown, the second inner layer 210 and the second outer layer 220 are arranged in the first area AR1 which is a partial area in the height direction HD so as to cover the entire circumference of the side surface of the refrigeration device 20 while sandwiching the middle layer 230. The middle layer 230 is arranged in the second area AR2 from the lower end in the height direction HD of the refrigeration device 20 to the first area AR1 so as to cover only a part of the side surface of the refrigeration device 20.

[0073] The reason why the intermediate layer 230 of the second vibration isolating member 200 is arranged to cover only a part of the area on the front panel 3c side is that if the second vibration isolating member 200 covers the entire circumference of the first vibration isolating member 100, it becomes difficult to install the second vibration isolating member 200. In addition, even if the intermediate layer 230 of the second vibration isolating member 200 does not cover the entire circumference of the first vibration isolating member 100, the intermediate layer 230 of the second vibration isolating member 200 can be in contact with the bottom panel 3b, and the position of the second vibration isolating member 200 in the height direction HD can be reliably fixed.

[0074] like Fig.10As shown in FIG. 1 , the second vibration isolating member 200 makes the position in the length direction LD of the end of the second region AR2 in the height direction HD of the intermediate layer 230 different from the position in the length direction LD of the end of the first region AR1 in the height direction HD of the first member 220a of the second outer layer 220. This is to prevent the breakage portion of the first member 220a and the second member 220b from being arranged at the same position as the end of the second region AR2 in the height direction HD of the intermediate layer 230. The end of the second region AR2 in the height direction HD of the intermediate layer 230 becomes a stress concentration portion, and therefore, by not arranging the breakage portion at this portion, deformation or damage of the intermediate layer 230 caused by stress concentration can be suppressed.

[0075] The outdoor unit 2 of the present embodiment described above exhibits the following operations and effects.

[0076] According to the outdoor unit 2 of this embodiment, the first vibration-proof member 100 is arranged in a region from the lower end to the upper end in the height direction HD of the refrigeration device 20 in a state of contacting at least a portion of the side surface of the refrigeration device 20 so as to cover the entire circumference of the side surface of the refrigeration device 20. Therefore, it is possible to appropriately prevent the vibration and noise during the operation of the refrigeration device 20 including the compressor 4 from being transmitted to the outside.

[0077] Furthermore, according to the outdoor unit 2 of the present embodiment, the second vibration-isolating member 200 is arranged in at least a portion of the region from the lower end to the upper end in the height direction HD so as to cover the entire circumference of the first vibration-isolating member 100 while in contact with at least a portion of the first vibration-isolating member 100. The second vibration-isolating member 200 is arranged in contact with both the first vibration-isolating member 100 and the adjacent components (the partition plate 3g, the fixing member 10) so as to fill the gaps CL1, CL2, CL3, CL4, CL5, and CL6 between the refrigeration device 20 and the adjacent components together with the first vibration-isolating member 100. Since the gaps between the refrigeration device 20 and the adjacent components are filled by the first vibration-isolating member 100 and the second vibration-isolating member 200, it is possible to appropriately prevent the displacement of the refrigeration device 20 including the compressor 4 due to severe vibration or shock during transportation, thereby preventing stress from being generated in the refrigeration device 20 or the piping connected to the refrigeration device 20 and causing damage.

[0078] According to the outdoor unit 2 of the present embodiment, the first thickness Th1 in the first circumferential region CA1 and the second thickness Th2 in the second circumferential region CA2 of the circumferential CD of the second vibration-isolating member 200 are different. Therefore, the second vibration-isolating member 200 can have an appropriate thickness according to the distance of the gap in the first circumferential region CA1 and the second circumferential region CA2 when the second vibration-isolating member 200 is installed, the rigidity of the adjacent components in the first circumferential region CA1 and the second circumferential region CA2, etc. For example, the thickness of the second vibration-isolating member 200 can be adjusted in a state where the second vibration-isolating member 200 is installed so that the rigidity of the second vibration-isolating member 200 in the first circumferential region CA1 is higher than the rigidity of the second vibration-isolating member 200 in the second circumferential region CA2, and the second vibration-isolating member 200 is in a state suitable for reducing the rigidity of the adjacent components or the vibration frequency of the compressor 4.

[0079] According to the outdoor unit 2 of this embodiment, by forming one of the first inner layer 110 and the first outer layer 120 of the first vibration-proof member 100 from a rubber material, the vibration-proof performance and the sound-proof performance can be fully ensured. In addition, by forming the other of the first inner layer 110 and the first outer layer 120 of the first vibration-proof member 100 from a member having lower rigidity than the rubber material, the external force to which the refrigeration equipment 20 including the compressor 4 is subjected under severe vibration or impact can be appropriately absorbed.

[0080] According to the outdoor unit 2 of the present embodiment, the second inner layer 210 and the second outer layer 220 of the second vibration-proof member 200 are arranged in the first area AR1, which is a partial area in the height direction HD of the refrigeration device 20, in a manner that covers the entire circumference of the side surface of the refrigeration device 20 while sandwiching the intermediate layer 230. Since the second vibration-proof member 200 covers the entire circumference of the side surface of the refrigeration device 20, it is possible to reliably prevent a space from being generated in the gap between the side surface of the refrigeration device 20 and an adjacent component.

[0081] According to the vibration-proof component mounting method of the present embodiment, the first vibration-proof component is arranged in the region from the lower end to the upper end in the height direction HD of the refrigeration device 20 in a manner covering the entire circumference of the side surface of the refrigeration device 20 while being in contact with at least a portion of the side surface of the refrigeration device 20. Therefore, it is possible to appropriately prevent the vibration and noise during the operation of the refrigeration device including the compressor from being transmitted to the outside.

[0082] Furthermore, according to the vibration-proof component mounting method of the present embodiment, the second vibration-proof component 200 is mounted on at least a portion of the region from the lower end to the upper end in the height direction of the refrigeration device in a manner that covers the entire circumference of the first vibration-proof component while in contact with at least a portion of the first vibration-proof component. The second vibration-proof component 200 is mounted in a manner that fills the gaps CL1, CL2, CL3, CL4, CL5, and CL6 between the side surface of the refrigeration device 20 and the adjacent components together with the first vibration-proof component 100 while in contact with both the first vibration-proof component 100 and the adjacent components. Since the gaps between the side surface of the refrigeration device 20 and the adjacent components are filled by the first vibration-proof component 100 and the second vibration-proof component 200, it is possible to appropriately prevent the displacement of the refrigeration device 20 including the compressor due to severe vibration or impact during transportation, thereby causing stress in the refrigeration device 20 or the piping connected to the refrigeration device 20 and causing damage.

[0085] In the outdoor unit 2 of the first embodiment, the first vibration-proofing member 100 and the second vibration-proofing member 200 are arranged to fill the gap CL6 between the compressor 4 and the muffler 13. In contrast, in the outdoor unit 2A of the present embodiment, the first vibration-proofing member 100 and the second vibration-proofing member 200 are arranged to fill the gap CL7 between the muffler 13 and the left side panel 3f.

[0086] like Fig.15 As shown, in the outdoor unit 2A of the present embodiment, the first vibration-proof member 100 and the second vibration-proof member 200 are arranged to fill the gap CL7 between the muffler 13 and the left side panel 3f. The left side panel 3f is a member constituting a part of the frame 3, so the vibration of the refrigeration device 20 can be reliably transmitted to the left side panel 3f via the muffler 13, thereby absorbing the vibration of the refrigeration device 20.

[0087] like Fig.15 As shown, according to the outdoor unit 2A of this embodiment, the refrigeration device 20 is Fig.15The vibration in the left-right direction in FIG. 15 is transmitted to the left side panel 3f and the partition 3g, so the vibration in the left-right direction can be reliably absorbed by the frame 3. In addition, according to the outdoor unit 2A of this embodiment, the vibration of the refrigeration device 20 in the front-back direction in FIG. 15 is transmitted to the fixing member 10 and the partition 3g, so the vibration in the front-back direction can be reliably absorbed by the frame 3.

Furthermore, the first vibration-proof component in contact with the second vibration-proof component can also be positioned in the height direction. Furthermore, since the intermediate layer is arranged to cover only a part of the side surface of the refrigeration equipment, the second vibration-proof component can be easily installed around the first vibration-proof component compared to the case where the intermediate layer is arranged to cover the entire circumference of the side surface of the refrigeration equipment.
