DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] [First embodiment] Hereinafter, the outdoor unit (compressor) 2 of the air conditioner 1 according to the first embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is a front view showing the outdoor unit 2 of the air conditioner 1 according to the first embodiment of the present disclosure. Fig. 1 is a plan view showing the outdoor unit 2 of the air conditioner 1 according to the first embodiment of the present disclosure. In Fig. 1, the direction perpendicular to the installation surface Su is defined as the height direction HD. Fig. 3 is a cross-sectional view of the outdoor unit 2 shown in Fig. 1 taken along the arrow AA, showing the state in which vibration-isolating members (first vibration-isolating member 100, second vibration-isolating member 200, third vibration-isolating member 300) have been attached.

[0011] The air conditioner 1 of this embodiment is equipped with a compressor 4 that compresses the refrigerant, a four-way switching valve (not shown) that switches the circulation direction of the refrigerant, an outdoor heat exchanger 5 that exchanges heat between the refrigerant and outside air, an expansion valve (not shown) that expands the refrigerant, and an indoor heat exchanger (not shown) that exchanges heat between the refrigerant and indoor air from an indoor fan (not shown), and is equipped with a closed refrigerant cycle in which these devices are connected by refrigerant piping 9. The various devices are housed in the indoor unit (not shown) or the outdoor unit 2.

[0012] As shown in Figures 1 and 2, the outdoor unit 2 includes a housing 3, a compressor 4, an outdoor heat exchanger 5, a blower 6 that guides outside air to the outdoor heat exchanger 5, a control box 7, a support portion 8 that supports the control box 7 relative to the housing 3, refrigerant piping 9, a fixing portion (adjacent member) 10 that fixes the refrigerant piping 9, a main accumulator 11, a sub-accumulator 12, and mufflers 13 and 14.

[0013] The housing 3 is a substantially rectangular parallelepiped member that constitutes the outer shell of the outdoor unit 2 and defines a space S therein. The control box 7 is a member that houses electrical components such as an inverter that controls the compressor 4 etc. The fixing member 10 is a member that is disposed adjacent to the compressor 4 and fixes the refrigerant piping 9 to the housing 3. Each part that constitutes the outdoor unit 2 is disposed in the space S.

[0014] The housing 3 has a top panel 3a that defines the top surface of the space S, a bottom panel 3b that defines the bottom surface of the space S, a front panel 3c that defines the front surface (one end surface) of the space S, a rear panel 3d that defines the rear surface of the space S, a right panel 3e that defines the right surface of the space S, and a left panel 3f that defines the left surface of the space S. The housing 3 has a partition wall 3g that separates a heat exchanger chamber S1 in which the outdoor heat exchanger 5 and the like are arranged, from a machine chamber S2 in which the compressor 4, the control box 7, and the like are arranged.

[0015] The compressor 4 is a device housed in the machine room S2 of the space S and 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 piping. In Fig. 1, other members disposed adjacent to the compressor 4 in the machine room S2 are omitted. In Fig. 2, some devices disposed in the machine room S2 are omitted.

[0016] The front panel 3c is configured to be partially or entirely openable. The front panel 3c is formed with an exhaust opening (not shown) for discharging outside 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 outside air into the outdoor unit 2.

[0017] The partition wall 3g is a member formed in an approximately L-shape when viewed in a plane, and has a first partition wall 3ga extending from the inner surface of the front panel 3c toward the outdoor heat exchanger 5, and a second partition wall 3gb extending from the end of the first partition wall 3ga on the outdoor heat exchanger 5 side toward the left side panel 3f.

[0018] The heat exchanger chamber S1 has an internal space that is approximately L-shaped in plan view. In the heat exchanger chamber S1, an exterior heat exchanger 5 that is approximately L-shaped in plan view is placed on the bottom panel 3b so as to be aligned with the right panel 3e and the rear panel 3d. In the heat exchanger chamber S1, a blower 6 that guides outside air to the exterior heat exchanger 5 and an electric motor 6a that drives the blower 6 are arranged.

[0019] The machine room S2 is a space partitioned by the front panel 3c, the left panel 3f, and the partition wall 3g. In the machine room S2, a compressor 4 is placed on the bottom panel 3b. A support part 8 supported by the first partition wall 3ga is provided at the top of the machine room S2. A control box 7 is supported by being suspended from the support part 8.

[0020] The refrigerant piping 9 is a piping for circulating the refrigerant that circulates through the refrigerant cycle. The refrigerant piping 9 is a general term for the piping provided in the machine room S2 of the outdoor unit 2. In Fig. 1 and Fig. 2, the refrigerant piping 9 that connects the compressor 4 and the muffler 14 is shown, but other refrigerant piping is not shown.

[0021] The fixing member 10 is a member for fixing the refrigerant pipes 9 to the housing 3. As shown in Fig. 3, one end of the fixing member 10 is fixed to the housing 3 by a fastening bolt 10a. As shown in Fig. 1, 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).

[0022] The main accumulator 11 and the sub accumulator 12 are devices used to separate the refrigerant to be supplied to the compressor 4 into gas and liquid. As shown in Fig. 2 and Fig. 3, the main accumulator 11 is disposed between the compressor 4 and the first partition wall 3ga when the outdoor unit 2 is viewed from above. The sub accumulator 12 is disposed between the compressor 4 and the second partition wall 3gb when the outdoor unit 2 is viewed from above.

[0023] The mufflers 13 and 14 are devices for reducing noise caused by the refrigerant flowing through the refrigerant pipes 9. As shown in Figures 2 and 3, 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 wall 3ga when the outdoor unit 2 is viewed from above.

[0024] 2 and 3, the compressor 4, the main accumulator 11, the sub accumulator 12, and mufflers 13 and 14 are disposed in the machine room S2. These devices disposed in the machine room S2 and circulating the refrigerant are collectively referred to as refrigerant equipment 20. Each device constituting the refrigerant equipment 20 is connected via refrigerant piping 9.

[0025] The partition wall 3g is attached to the housing 3 by a fastening bolt (not shown). As shown in Fig. 2 and Fig. 3, the partition wall 3g is disposed adjacent to the main accumulator 11 constituting the refrigerant equipment 20 with a gap CL1 provided between the partition wall 3g and the main accumulator 11 constituting the refrigerant equipment 20 in the horizontal direction parallel to the installation surface Su. The partition wall 3g is also disposed adjacent to the muffler 14 constituting the refrigerant equipment 20 with a gap CL2 provided between the partition wall 3g and the muffler 14 constituting the refrigerant equipment 20 in the horizontal direction. The partition wall 3g is also disposed adjacent to the refrigerant pipe 9 constituting the refrigerant equipment 20 with a gap CL3 provided between the partition wall 3g and the refrigerant pipe 9 constituting the refrigerant equipment 20 in the horizontal direction.

[0026] The fixing member 10 is attached to the housing 3 with fastening bolts 10a. As shown in Fig. 2 and Fig. 3, the fixing member 10 is disposed adjacent to the main accumulator 11 constituting the refrigerant equipment 20 with a gap CL4 provided between the fixing member 10 and the main accumulator 11 in the horizontal direction parallel to the installation surface Su.

[0027] Moreover, the fixing member 10 is disposed adjacent to the compressor 4 constituting the refrigerant equipment 20 with a gap CL5 provided between the fixing member 10 and the compressor 4 in the horizontal direction. Muffler 13 is attached to housing 3 via refrigerant piping 9 and fixing member 10. As shown in Figures 2 and 3, muffler 13 is disposed adjacent to compressor 4 with a gap CL6 provided between muffler 13 and compressor 4 in the horizontal direction.

[0028] In this embodiment, in order to prevent the refrigerant equipment 20 arranged in the machine room S2 from being displaced due to strong vibrations and impacts during transportation, and thereby from being damaged due to stress generated in the refrigerant equipment 20 and the refrigerant piping 9 connected to the refrigerant equipment 20, a first vibration-isolating member 100 and a second vibration-isolating member 200 are attached to the refrigerant equipment 20. The first vibration-isolating member 100 is attached to the refrigerant equipment 20 so as to cover the entire circumference of the side surface of the compressor 4 along the circumferential direction CD. The second vibration-isolating member 200 is attached to the refrigerant equipment 20 so as to fill at least the gaps CL1, CL2, CL3, CL4, CL5, and CL6.

[0029] Next, the first vibration-isolating member 100, second vibration-isolating member 200, and third vibration-isolating member 300 attached to the refrigerant equipment 20 of this embodiment will be described with reference to the drawings. Fig. 4 is a cross-sectional view taken along the line AA of the outdoor unit 2 shown in Fig. 1, showing a state in which the vibration-isolating members (first vibration-isolating member 100, second vibration-isolating member 200, third vibration-isolating member 300) are not attached. Fig. 5 is a cross-sectional view taken along the line AA of the outdoor unit shown in Fig. 1, showing a state in which the first vibration-isolating member 100 is attached.

[0030] When attaching the first vibration-isolating member 100, the second vibration-isolating member 200, and the third vibration-isolating member 300 to the refrigerant equipment 20 of this embodiment, the following procedures are performed. First, the first vibration-isolating member 100 is attached to the region from the lower end to the upper end in the height direction of the refrigerant equipment 20 so as to cover the entire circumference of the compressor 4 and the main accumulator 11 in the state shown in Fig. 4 (first attachment step). This brings the first vibration-isolating member 100 into contact with at least a portion of the side surfaces of the compressor 4 and the main accumulator 11. In this step, the first vibration-isolating member 100 is attached without contacting the partition wall 3g and the fixing member 10.

[0031] Secondly, the second vibration-isolating member 200 is attached to at least a part of the region from the lower end to the upper end in the height direction HD of the refrigerant equipment 20 so as to cover the entire periphery of the first vibration-isolating member 100 in the state shown in Fig. 5 (second attachment step). This brings the second vibration-isolating member 200 into contact with at least a part of the first vibration-isolating member 100.

[0032] At this time, the second vibration-isolating member 200 is attached so as to fill the gaps CL1, CL2, and CL3 together with the first vibration-isolating member 100 while in contact with both the first vibration-isolating member 100 and the partition wall 3g. The second vibration-isolating member 200 is also attached so as to fill the gaps CL4 and CL5 together with the first vibration-isolating member 100 while in contact with both the first vibration-isolating member 100 and the fixed member 10. The second vibration-isolating member 200 is also attached so as to fill the gap CL6 together with the first vibration-isolating member 100 while in contact with both the first vibration-isolating member 100 and the muffler 13.

[0033] Thirdly, the third vibration-isolating member 300 is arranged so as to seal the upper side of the compressor 4 and main accumulator 11 covered by the first vibration-isolating member 100. By arranging the third vibration-isolating member 300, the lower side of the compressor 4 and main accumulator 11 is covered by the bottom panel 3b, the sides are covered by the first vibration-isolating member and the second vibration-isolating member 200, and the upper side is covered by the third vibration-isolating member 300. The third vibration-isolating member 300 is formed, for example, from felt formed into a sheet by compressing animal fibers or other fibers. By performing the above operations, the state shown in FIG. 3 is achieved.

[0034] The first vibration-isolating member 100, the second vibration-isolating member 200 and the third vibration-isolating member 300 of this embodiment may be attached only during transportation of the outdoor unit 2, but may also be left attached not only during transportation of the outdoor unit 2 but also during operation of the outdoor unit 2 after installation. By attaching the first vibration-isolating member 100, the second vibration-isolating member 200 and the third vibration-isolating member 300 to the refrigerant equipment 20 while the outdoor unit 2 is in operation, vibrations and noise of the refrigerant equipment 20 can be appropriately suppressed.

[0035] Next, the detailed configuration of the first vibration-proofing member 100 will be described with reference to the drawings. FIG. 6 is a plan view showing the first vibration-proofing member 100. FIG. 7 is a cross-sectional view of the first vibration-proofing member 100 in FIG. 6 taken along the line BB. As shown in FIG. 6, the first vibration-proofing member 100 is an elongated member having a length L12 in the longitudinal direction LD longer than a length L11 in the height direction HD. As shown in FIG. 7, the first vibration-proofing 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 together, for example, by an adhesive.

[0036] The first inner layer 110 is a member arranged in contact with the compressor 4 and the main accumulator 11. The first outer layer 120 is a member arranged in contact with the first inner layer 110 and the second vibration-damping member 200. As shown in FIG. 7, 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 because a first end 120a of the first outer layer 120 in the longitudinal direction LD and a second end 120b of the first outer layer 120 in the longitudinal direction LD are joined by an adhesive or the like.

[0037] The first inner layer 110 is formed, for example, from felt formed by compressing animal fibers or other fibers into a sheet shape. The first outer layer 120 is formed from a material that exhibits high soundproofing properties (for example, a rubber material). The first inner layer 110 may be formed from other members having lower rigidity than the rubber material. Also, a modified example may be adopted in which the first inner layer 110 is formed from a rubber material and the first outer layer 120 is formed from other materials having lower rigidity than the rubber material.

[0038] Fig. 8 is a cross-sectional view showing a state in which the first vibration-proof member 100 is attached to the compressor 4 and the main accumulator 11. As shown in Fig. 8, the first vibration-proof member 100 is disposed so as to cover the compressor 4 and the main accumulator 11 along the circumferential direction CD while being in contact with a side surface 4a of the compressor 4 and a portion of a side surface 11a of the main accumulator 11. The first vibration-proof member 100 maintains a state in which it covers the compressor 4 and the main accumulator 11 by bonding a first end portion 120a in the longitudinal direction LD of the first outer layer 120 and a second end portion 120b in the longitudinal direction LD of the first outer layer 120 with an adhesive or the like.

[0039] Fig. 9 is a front view showing a state in which the first vibration-proof member 100 is attached to the compressor 4 and the main accumulator 11. As shown in Fig. 9, the first vibration-proof 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.

[0040] 5, when the first vibration-proof member 100 is attached to the compressor 4 and the main accumulator 11, it is disposed so as not to contact the adjacent partition wall 3g, the fixed member 10, the refrigerant pipe 9, and the muffler 14. Since there is sufficient space in a gap CL1 between the main accumulator 11 and the partition wall 3g, a gap CL2 between the muffler 14 and the partition wall 3g, a gap CL3 between the refrigerant pipe 9 and the partition wall 3g, a gap CL4 between the main accumulator 11 and the fixed member 10, a gap CL5 between the compressor 4 and the fixed member 10, and a gap CL6 between the compressor 4 and the muffler 13, the first vibration-proof member 100 can be attached to the compressor 4 and the main accumulator 11 relatively easily.

[0041] Next, the detailed configuration of the second vibration-isolating member 200 will be described with reference to the drawings. Fig. 10 is a plan view showing the second vibration-isolating member 200. Fig. 11 is a cross-sectional view taken along the arrow CC of the second vibration-isolating member 200 in Fig. 10. As shown in Fig. 10, the second vibration-isolating member 200 is an elongated member whose length L22 in the longitudinal direction LD is longer than its length L21 in the height direction HD.

[0042] 11, the second vibration-damping member 200 is configured 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 first inner layer 110 and the intermediate layer 230, and the first outer layer 120 and the intermediate layer 230 are bonded together, for example, by an adhesive.

[0043] The second inner layer 210 is a member arranged in contact with the first vibration-proof member 100. The second outer layer 220 is a member arranged in contact with the second inner layer 210 and other adjacent members (e.g., the partition 3g and the fixing member 10). As shown in FIG. 11, 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 for joining a first end 230a of the intermediate layer 230 in the longitudinal direction LD and a second end 230b of the intermediate layer 230 in the longitudinal direction LD.

[0044] For example, a hook-and-loop fastener is attached to 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 second vibration-proof member 200 can be easily attached and detached by appropriately switching between a state in which the first end 230a and the second end 230b are joined and a state in which the first end 230a and the second end 230b are not joined.

[0045] The second inner layer 210 and the second outer layer 220 are formed, for example, from felt formed by compressing animal fibers or other fibers into a sheet shape. The middle layer 230 is formed from a material (for example, a resin material such as polyvinyl 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 from another member having lower rigidity than the middle layer 230.

[0046] 11, the second outer layer 220 of the second vibration-damping 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 disposed in the gaps CL1, CL2, CL3, CL4, CL5, CL6, the first thickness Th1 in a first circumferential region CA1 in the circumferential direction CD surrounding the side surface of the refrigerant equipment 20 is different from the second thickness Th2 in a second circumferential region CA2 different from the first circumferential region CA1.

[0047] For example, the first thickness Th1 and the second thickness Th2 of the second vibration-damping member 200 can be adjusted so that the rigidity of the second vibration-damping member 200 in the first circumferential region CA1 is higher than the rigidity of the second vibration-damping member 200 in the second circumferential region CA2 when the second vibration-damping member 200 is attached, thereby achieving a state suitable for reducing the rigidity of other adjacent members and the vibration frequency of the compressor. Note that a modified example in which the second outer layer 220 of the second vibration-damping member 200 has the same thickness over the entire region in the circumferential direction CD may be adopted.

[0048] Fig. 12 is a cross-sectional view showing a state in which the second vibration-isolating member 200 is attached to the refrigerant equipment 20 at the height at which the fixing member 10 is disposed. As shown in Fig. 12, the second vibration-isolating member 200 is disposed so as to cover the entire circumference of the first vibration-isolating member 100 along the circumferential direction CD in a state in which the second vibration-isolating member 200 is in contact with a part of the first vibration-isolating member 100. The second vibration-isolating member 200 maintains a state in which it covers the first vibration-isolating member 100 by joining a first end 230a in the longitudinal direction LD of the intermediate layer 230 and a second end 230b in the longitudinal direction LD of the intermediate layer 230.

[0049] 12, the second vibration-isolating member 200 is disposed so as 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 wall 3g. The second vibration-isolating member 200 is disposed so as 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 fixed member 10. The second vibration-isolating member 200 is disposed so as 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.

[0050] Fig. 13 is a cross-sectional view showing a state in which the second vibration-isolating member 200 is attached to the refrigerant equipment 20 at a position lower than the height at which the fixing member 10 is arranged. As shown in Fig. 13, at a position lower than the height at which 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 portion of the entire periphery of the first vibration-isolating member 100 on the front panel 3c side.

[0051] Fig. 14 is a front view showing a state in which the second vibration-proof member 200 is attached to the refrigerant equipment 20. As shown in Fig. 14, the second vibration-proof member 200 is arranged in a part of the region from the lower end to the upper end in the height direction HD of the refrigerant equipment 20. As shown in Figs. 10 and 14, the second inner layer 210 and the second outer layer 220 are arranged in a first region AR1, which is a part of the region in the height direction HD, so as to cover the entire circumference of the side surface of the refrigerant equipment 20 with the intermediate layer 230 sandwiched therebetween. The intermediate layer 230 is arranged in a second region AR2 from the lower end of the height direction HD of the refrigerant equipment 20 to the first region AR1 so as to cover only a part of the side surface of the refrigerant equipment 20.

[0052] The reason why the intermediate layer 230 of the second vibration-isolating member 200 is disposed so as to cover only a partial area on the front panel 3c side is that if the entire periphery of the first vibration-isolating member 100 is covered with the second vibration-isolating member 200, it would be difficult to attach the second vibration-isolating member 200. Also, even if the intermediate layer 230 of the second vibration-isolating member 200 does not cover the entire periphery of the first vibration-isolating member 100, the intermediate layer 230 of the second vibration-isolating member 200 can come into 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.

[0053] 10, in the second vibration-proof member 200, the position in the longitudinal direction LD of the end of the second region AR2 in the height direction HD of the intermediate layer 230 is different from the position in the longitudinal 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 because a gap between the first member 220a and the second member 220b is not disposed 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 is a stress concentration location, so by not disposing a gap at this location, deformation or damage of the intermediate layer 230 due to stress concentration can be suppressed.

[0054] The outdoor unit 2 of the present embodiment described above provides the following actions and effects. According to the outdoor unit 2 of the present embodiment, the first vibration-proof member 100 is disposed in a region from the lower end to the upper end in the height direction HD of the refrigerant equipment 20 so as to cover the entire periphery of the side surface of the refrigerant equipment 20 while being in contact with at least a part of the side surface of the refrigerant equipment 20. This makes it possible to appropriately prevent vibrations and noise during operation of the refrigerant equipment 20, including the compressor 4, from being transmitted to the outside.

[0055] Moreover, according to the outdoor unit 2 of this embodiment, the second vibration-isolating member 200 is disposed in at least a part 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 in a state of contact with at least a part of the first vibration-isolating member 100. The second vibration-isolating member 200 is disposed so as to fill the gaps CL1, CL2, CL3, CL4, CL5, CL6 between the refrigerant equipment 20 and the adjacent members together with the first vibration-isolating member 100 in a state of contact with both the first vibration-isolating member 100 and the adjacent members (partition wall 3g, fixing member 10). Since the gaps between the refrigerant equipment 20 and the adjacent members are filled by the first vibration-isolating member 100 and the second vibration-isolating member 200, it is possible to appropriately prevent damage caused by stress generated in the refrigerant equipment 20 and the piping connected to the refrigerant equipment 20 due to displacement of the refrigerant equipment 20 including the compressor 4 caused by violent vibrations and impacts during transportation.

[0056] According to the outdoor unit 2 of this embodiment, the first thickness Th1 in the first circumferential region CA1 in the circumferential direction CD of the second vibration-proof member 200 is different from the second thickness Th2 in the second circumferential region CA2. Therefore, the second vibration-proof member 200 can be made to have an appropriate thickness depending on the distance of the gap in the first circumferential region CA1 and the second circumferential region CA2 when the second vibration-proof member 200 is attached, the rigidity of adjacent members in the first circumferential region CA1 and the second circumferential region CA2, etc. For example, the thickness of the second vibration-proof member 200 can be adjusted so that the rigidity of the second vibration-proof member 200 in the first circumferential region CA1 is higher than the rigidity of the second vibration-proof member 200 in the second circumferential region CA2 in a state where the second vibration-proof member 200 is attached, and a state suitable for reducing the rigidity of adjacent members and the vibration frequency of the compressor 4 can be achieved.

[0057] 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-damping member 100 from a rubber material, it is possible to ensure sufficient vibration-damping and sound-proofing performance. Furthermore, by forming the other of the first inner layer 110 and the first outer layer 120 of the first vibration-damping member 100 from a material having a lower rigidity than a rubber material, it is possible to appropriately absorb external forces that the refrigerant equipment 20 including the compressor 4 receives due to severe vibrations and impacts.

[0058] According to the outdoor unit 2 of this embodiment, the second inner layer 210 and the second outer layer 220 of the second vibration-damping member 200 are arranged in a first region AR1, which is a partial region in the height direction HD of the refrigerant equipment 20, so as to cover the entire periphery of the side surface of the refrigerant equipment 20 with the intermediate layer 230 sandwiched between them. Because the entire periphery of the side surface of the refrigerant equipment 20 is covered with the second vibration-damping member 200, it is possible to reliably prevent the occurrence of spaces in gaps between the side surface of the refrigerant equipment 20 and adjacent members.

[0059] According to the vibration-isolating member mounting method of the present embodiment, the first vibration-isolating member is mounted in a region from the lower end to the upper end in the height direction HD of the refrigerant equipment 20 so as to cover the entire periphery of the side surface of the refrigerant equipment 20 while being in contact with at least a portion of the side surface of the refrigerant equipment 20. This makes it possible to appropriately prevent vibrations and noise generated during operation of the refrigerant equipment including the compressor from being transmitted to the outside.

[0060] According to the vibration-isolating member mounting method according to the first aspect of the present disclosure, the second vibration-isolating member 200 is mounted to at least a part of the region from the lower end to the upper end in the height direction of the refrigerant equipment so as to cover the entire circumference of the first vibration-isolating member while contacting at least a part of the first vibration-isolating member. The second vibration-isolating member 200 is mounted so as to fill the gaps CL1, CL2, CL3, CL4, CL5, and CL6 between the side surface of the refrigerant equipment 20 and the adjacent member together with the first vibration-isolating member 100 while contacting both the first vibration-isolating member 100 and the adjacent member. Since the gaps between the side surface of the refrigerant equipment 20 and the adjacent member are filled by the first vibration-isolating member 100 and the second vibration-isolating member 200, it is possible to appropriately prevent the refrigerant equipment 20 including the compressor from being displaced due to strong vibrations and impacts during transportation, which causes stress to be generated in the refrigerant equipment 20 and the piping connected to the refrigerant equipment 20 and damage to the refrigerant equipment 20.

[0061] Second Embodiment Next, an outdoor unit 2A of an air conditioner according to a second embodiment of the present disclosure will be described with reference to the drawings. Fig. 15 is a cross-sectional view of the outdoor unit 2A according to the second embodiment of the present disclosure, showing a state in which vibration-isolating members (first vibration-isolating member 100, second vibration-isolating member 200, third vibration-isolating member 300) are attached.

[0062] In the outdoor unit 2 of the first embodiment, the first vibration-isolating member 100 and the second vibration-isolating member 200 are arranged so as 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-isolating member 100 and the second vibration-isolating member 200 are arranged so as to fill the gap CL7 between the muffler 13 and the left panel 3f.

[0063] 15, in the outdoor unit 2A of the present embodiment, the first vibration-isolating member 100 and the second vibration-isolating member 200 are arranged to fill the gap CL7 between the muffler 13 and the left side panel 3f. Because the left side panel 3f is a member that constitutes part of the housing 3, vibrations of the refrigerant equipment 20 can be reliably transmitted to the left side panel 3f via the muffler 13, and the vibrations of the refrigerant equipment 20 can be absorbed.

[0064] As shown in Fig. 15, according to the outdoor unit 2A of the present embodiment, vibrations of the refrigerant equipment 20 in the left-right direction in Fig. 15 are transmitted to the left panel 3f and the partition wall 3g, so that the vibrations in the left-right direction can be reliably absorbed by the housing 3. Also, according to the outdoor unit 2A of the present embodiment, vibrations of the refrigerant equipment 20 in the front-rear direction in Fig. 15 are transmitted to the fixing member 10 and the partition wall 3g, so that the vibrations in the front-rear direction can be reliably absorbed by the housing 3.

[0065] The compression device (2) according to each of the embodiments described above can be understood, for example, as follows.

[0066] The compression device according to a first aspect of the present disclosure includes a housing (3) that defines a space (S) therein and has an openable and closable panel (3c) that defines an end face on one side of the space, refrigerant equipment (20) that is housed in the space and arranged at a position facing the panel and includes a compressor (4) that compresses a refrigerant, adjacent members (3g, 10) that are attached to the housing and arranged adjacent to the refrigerant equipment with gaps (CL1, CL2, CL3) provided between them in the horizontal direction, and a compressor (4) that covers the entire circumference of the compressor while contacting at least a portion of a side surface of the compressor. The refrigerant equipment has a first vibration-isolating member (100) arranged in a region from the lower end to the upper end in the height direction (HD) of the compressor, and a second vibration-isolating member (200) arranged in at least a portion of the region from the lower end to the upper end in the height direction of the refrigerant equipment so as to cover the entire circumference of the first vibration-isolating member while being in contact with at least a portion of the first vibration-isolating member, wherein the first vibration-isolating member is arranged without being in contact with the adjacent member, and the second vibration-isolating member is arranged to fill the gap together with the first vibration-isolating member while being in contact with both the first vibration-isolating member and the adjacent member.

[0067] According to the compressor device of the first aspect of the present disclosure, the first vibration isolating member is disposed in a region from the lower end to the upper end in the height direction of the compressor so as to cover the entire circumference of the compressor while being in contact with at least a part of the side surface of the compressor, thereby making it possible to appropriately prevent vibrations and noises generated during operation of the compressor from being transmitted to the outside.

[0068] Furthermore, according to the compression device according to the first aspect of the present disclosure, a second vibration-isolating member is disposed in at least a part of the region from the lower end to the upper end in the height direction so as to cover the entire circumference of the first vibration-isolating member while being in contact with at least a part of the first vibration-isolating member. The second vibration-isolating member is disposed so as to fill the gap between the refrigerant equipment and the adjacent member together with the first vibration-isolating member while being in contact with both the first vibration-isolating member and the adjacent member. Since the gap between the refrigerant equipment and the adjacent member is filled by the first vibration-isolating member and the second vibration-isolating member, it is possible to appropriately prevent damage caused by stress generated in the refrigerant equipment and piping connected to the refrigerant equipment due to displacement of the refrigerant equipment including the compressor caused by severe vibrations and impacts during transportation.

[0069] The compression device according to the second aspect of the present disclosure is further configured as follows in the first aspect: That is, when the second vibration-proof member is not disposed in the gap, a first thickness (Th1) in a first circumferential region (CA1) in the circumferential direction surrounding the side surface of the refrigerant equipment is different from a second thickness (Th2) in a second circumferential region (CA2) different from the first circumferential region.

[0070] According to the compression device according to the second aspect of the present disclosure, the first thickness in the first circumferential region in the circumferential direction of the second vibration-proofing member is different from the second thickness in the second circumferential region. Therefore, the second vibration-proofing member can be made to have an appropriate thickness depending on the distance of the gap in the first circumferential region and the second circumferential region when the second vibration-proofing member is attached, the rigidity of adjacent members in the first circumferential region and the second circumferential region, etc. For example, the thickness of the second vibration-proofing member can be adjusted so that the rigidity of the second vibration-proofing member in the first circumferential region is higher than the rigidity of the second vibration-proofing member in the second circumferential region when the second vibration-proofing member is attached, thereby making it possible to achieve a state suitable for reducing the rigidity of adjacent members and the vibration frequency of the compressor.

[0071] The compression device according to a third aspect of the present disclosure is the first or second aspect, further configured as follows: The first vibration-damping member is configured by laminating a first inner layer (110) arranged in contact with the refrigerant equipment and a first outer layer (120) arranged in contact with the first inner layer and the second vibration-damping member, one of the first inner layer and the first outer layer being formed from a rubber material, and the other of the first inner layer and the first outer layer being formed from a material having a lower rigidity than the rubber material.

[0072] According to the compression device of the third aspect of the present disclosure, one of the first inner layer and the first outer layer of the first vibration-proofing member is made of a rubber material, thereby ensuring sufficient vibration-proofing and soundproofing performance. Also, by making the other of the first inner layer and the first outer layer of the first vibration-proofing member of a material having a lower rigidity than the rubber material, it is possible to appropriately absorb external forces such as strong vibrations and shocks that the refrigerant equipment including the compressor receives.

[0073] A compression device according to a fourth aspect of the present disclosure is any one of the first to third aspects, further configured as follows: The second vibration-damping member is configured by laminating a second inner layer (210) arranged in contact with the first vibration-damping member, a second outer layer (220) arranged in contact with the adjacent member, and an intermediate layer (230) sandwiched between the second inner layer and the second outer layer, the second inner layer and the second outer layer are arranged in a first region (AR1) that is a partial region in the height direction of the refrigerant equipment so as to cover the entire periphery of the side surface of the refrigerant equipment with the intermediate layer sandwiched therebetween, and the intermediate layer has a higher rigidity than the second inner layer and the second outer layer, and is arranged in a second region (AR2) from the lower end of the height direction of the refrigerant equipment to the first region so as to cover only a portion of the side surface of the compressor.

[0074] According to the compression device of the fourth aspect of the present disclosure, the second inner layer and the second outer layer of the second vibration-damping member are arranged in a first region, which is a partial region in the height direction of the refrigerant equipment, so as to cover the entire periphery of the side surface of the refrigerant equipment with the intermediate layer sandwiched between them. Since the entire periphery of the side surface of the refrigerant equipment is covered with the second vibration-damping member, it is possible to reliably prevent the occurrence of a space in the gap between the side surface of the refrigerant equipment and an adjacent member.

[0075] Furthermore, according to the compression device according to the fourth aspect of the present disclosure, an intermediate layer having higher rigidity than the second inner layer and the second outer layer is disposed in a second region from the lower end in the height direction of the refrigerant equipment to the first region. Therefore, the second vibration-proof member is positioned in the height direction by the intermediate layer with respect to the bottom surface on which the compressor is installed. Also, the first vibration-proof member in contact with the second vibration-proof member is positioned in the height direction. Furthermore, since the intermediate layer is disposed so as to cover only a portion of the side surface of the refrigerant equipment, the second vibration-proof member can be easily attached around the first vibration-proof member compared to a case in which the intermediate layer is disposed so as to cover the entire circumference of the side surface of the refrigerant equipment.

[0076] A vibration-proof member mounting method according to a fifth aspect of the present disclosure is a method for mounting a vibration-proof member to a refrigerant equipment including a compressor housed in a compression device, the compression device comprising: a housing having a space formed therein and a panel that defines an end face on one side of the space and that can be opened and closed; refrigerant equipment that is housed in the space and arranged in a position facing the panel and includes the compressor for compressing a refrigerant; and an adjacent member that is attached to the housing and arranged adjacent to the refrigerant equipment with a gap provided between it and the refrigerant equipment in the horizontal direction; The method includes a first installation step of attaching a first vibration-damping member to an area from the lower end to the upper end in the height direction of the refrigerant equipment so as to cover the entire circumference of the first vibration-damping member and contact at least a portion of the side of the compressor, and a second installation step of attaching a second vibration-damping member to at least a portion of the area from the lower end to the upper end in the height direction of the refrigerant equipment so as to cover the entire circumference of the first vibration-damping member and contact at least a portion of the first vibration-damping member, wherein the first installation step attaches the first vibration-damping member without contacting the adjacent member, and the second installation step attaches the second vibration-damping member so as to fill the gap together with the first vibration-damping member while contacting both the first vibration-damping member and the adjacent member.

[0077] According to the vibration-isolating member mounting method according to the fifth aspect of the present disclosure, the first vibration-isolating member is mounted in a region from the lower end to the upper end in the height direction HD of the compressor so as to cover the entire circumference of the compressor while contacting at least a part of the side surface of the compressor, thereby making it possible to appropriately prevent vibrations and noises generated during operation of the compressor from being transmitted to the outside.

[0078] According to the vibration-isolating member mounting method according to the first aspect of the present disclosure, a second vibration-isolating member is mounted to at least a part of a region from the lower end to the upper end in the height direction of the refrigerant equipment so as to cover the entire circumference of the first vibration-isolating member while contacting at least a part of the first vibration-isolating member. The second vibration-isolating member is mounted so as to fill a gap between a side surface of the refrigerant equipment and an adjacent member together with the first vibration-isolating member while contacting both the first vibration-isolating member and the adjacent member. Since the gap between the side surface of the refrigerant equipment and the adjacent member is filled by the first vibration-isolating member and the second vibration-isolating member, it is possible to appropriately prevent damage caused by stress generated in the refrigerant equipment and piping connected to the refrigerant equipment due to displacement of the refrigerant equipment including the compressor caused by severe vibrations and impacts during transportation.
