AI Technical Summary
The existing outdoor units of refrigeration cycle devices face challenges in preventing abnormal noise due to refrigerant piping vibrations when routed between the accumulator and the side panel, leading to potential contact and increased size in the vertical direction.
The outdoor unit design includes a refrigerant piping arrangement supported by elastic components between the liquid receiver and the opposing wall, using a support system with elastic parts to absorb vibrations and prevent noise, while maintaining a compact vertical profile.
This solution effectively suppresses abnormal noise and prevents damage from piping vibrations, allowing for efficient use of space and reducing the overall size of the outdoor unit.

Description
Outdoor unit and refrigeration cycle device
[0001] The present disclosure relates to an outdoor unit and a refrigeration cycle device.
[0002] For example, as described in Patent Document 1, an outdoor unit of a refrigeration cycle device equipped with an accumulator (receiver) is known.
[0003] JP 2010-71531 A
[0004] In the outdoor unit described above, as in Patent Document 1, a portion of the refrigerant piping through which the refrigerant flows may be located below the accumulator. However, in this case, the outdoor unit is likely to become larger in the vertical direction. To address this issue, it is possible to prevent the outdoor unit from becoming larger in the vertical direction by passing a portion of the refrigerant piping between the accumulator and a side panel (facing wall portion) of the housing. However, because the space between the accumulator and the side panel is likely to be narrow, passing a portion of the refrigerant piping between the accumulator and the side panel may cause the refrigerant piping to come into contact with the accumulator and the side panel when the refrigerant piping vibrates, resulting in abnormal noise.
[0005] In view of the above circumstances, one of the objects of the present disclosure is to provide an outdoor unit that can suppress the generation of abnormal noise while passing refrigerant piping between a receiver and an opposing wall portion of a housing that faces the receiver, and a refrigeration cycle apparatus that is equipped with such an outdoor unit.

[0007] One aspect of the refrigeration cycle apparatus according to the present disclosure includes the outdoor unit described above.
[0008] According to the present disclosure, in an outdoor unit of a refrigeration cycle device, it is possible to suppress the generation of abnormal noise while passing a refrigerant pipe between a receiver and an opposing wall portion of a housing that faces the receiver.

[0013] Embodiment 1. Fig. 1 is a schematic diagram showing a general configuration of a refrigeration cycle apparatus 100 in embodiment 1. The refrigeration cycle apparatus 100 is an apparatus that utilizes a refrigeration cycle in which a refrigerant R circulates. In embodiment 1, the refrigeration cycle apparatus 100 is an air conditioner. As shown in Fig. 1, the refrigeration cycle apparatus 100 includes an outdoor unit 10, an indoor unit 20, and a circulation path portion 18.
[0014] The outdoor unit 10 is disposed outdoors. The indoor unit 20 is disposed indoors. The outdoor unit 10 and the indoor unit 20 are connected to each other by a circulation path 18 through which a refrigerant R circulates. The outdoor unit 10 and the indoor unit 20 are heat exchange units that exchange heat with the air. The refrigeration cycle apparatus 100 can adjust the temperature of the air in the room where the indoor unit 20 is disposed by exchanging heat between the refrigerant R flowing in the circulation path 18 and the air in the room.
[0015] Examples of the refrigerant R flowing through the circulation path 18 include fluorine-based refrigerants or hydrocarbon-based refrigerants with low global warming potential (GWP). Examples of the refrigerant R include a single refrigerant selected from R1234yf, R1234ze, R32, and R290, a mixture of two or more of these, or a mixture of any of these with another refrigerant. Examples of the refrigerant R include a mixture of R1132(E) and R1123. Examples of refrigerant R include mixed refrigerants of R516A, R445A, R444A, R454C, R444B, R454A, R455A, R457A, R459B, R452B, R454B, R447B, R447A, R446A, and R459A.
[0016] The outdoor unit 10 includes a housing 11, a compressor 12, a heat exchanger 13, an expansion valve 14, a blower 15, a four-way valve 16, a control unit 17, and a liquid receiver 30. The housing 11 accommodates the compressor 12, the heat exchanger 13, the expansion valve 14, the blower 15, the four-way valve 16, the control unit 17, and the liquid receiver 30. The control unit 17 controls each part of the outdoor unit 10. The control unit 17 is, for example, a system control unit that oversees the overall control of the refrigeration cycle apparatus 100.
[0017] The compressor 12, the heat exchanger 13, the expansion valve 14, the four-way valve 16, and the receiver 30 are provided in a portion of the circulation path 18 that is located inside the housing 11. The compressor 12, the heat exchanger 13, the expansion valve 14, the four-way valve 16, and the receiver 30 are connected by a portion of the circulation path 18 that is located inside the housing 11.
[0018] The four-way valve 16 is provided in a portion of the circulation path portion 18 that is connected to the discharge side of the compressor 12. The four-way valve 16 can reverse the direction of the refrigerant R flowing through the circulation path portion 18 by switching a portion of the path of the circulation path portion 18. When the path connected by the four-way valve 16 is the path shown by the solid line on the four-way valve 16 in Fig. 1, the refrigerant R flows through the circulation path portion 18 in the direction shown by the solid arrow in Fig. 1. On the other hand, when the path connected by the four-way valve 16 is the path shown by the dashed line on the four-way valve 16 in Fig. 1, the refrigerant R flows through the circulation path portion 18 in the direction shown by the dashed arrow in Fig. 1.
[0019] The indoor unit 20 has a housing 21, a heat exchanger 22, and a blower 23. The heat exchanger 22 and the blower 23 are housed inside the housing 21. The indoor unit 20 is capable of cooling operation to cool the air in the room where the indoor unit 20 is located, and heating operation to warm the air in the room where the indoor unit 20 is located.
[0020] When the indoor unit 20 is in cooling operation, the refrigerant R flowing through the circulation path portion 18 flows in the direction shown by the solid arrow in Fig. 1. In other words, when the indoor unit 20 is in cooling operation, the refrigerant R flowing through the circulation path portion 18 circulates through the compressor 12, the heat exchanger 13 of the outdoor unit 10, the expansion valve 14, the heat exchanger 22 of the indoor unit 20, and the receiver 30 in that order, before returning to the compressor 12. During cooling operation, the heat exchanger 13 in the outdoor unit 10 functions as a condenser, and the heat exchanger 22 in the indoor unit 20 functions as an evaporator.
[0021] On the other hand, when the indoor unit 20 is in heating operation, the refrigerant R flowing in the circulation path portion 18 flows in the direction shown by the dashed line in Fig. 1. In other words, when the indoor unit 20 is in heating operation, the refrigerant R flowing in the circulation path portion 18 circulates through the compressor 12, the heat exchanger 22 of the indoor unit 20, the expansion valve 14, the heat exchanger 13 of the outdoor unit 10, and the receiver 30 in that order, before returning to the compressor 12. During heating operation, the heat exchanger 13 in the outdoor unit 10 functions as an evaporator, and the heat exchanger 22 in the indoor unit 20 functions as a condenser.
[0022] Next, the outdoor unit 10 of the first embodiment will be described in further detail. Fig. 2 is a perspective view showing the outdoor unit 10. Fig. 3 is a perspective view showing a part of the outdoor unit 10. In Fig. 3, a part of the housing 11 is not shown. As shown in Fig. 2, the housing 11 is in the shape of a substantially rectangular parallelepiped box having surfaces facing in the front-rear direction X, the left-right direction Y, and the vertical direction Z.
[0023] As shown in FIG. 3 , the housing 11 has a blower chamber 11a and a machine chamber 11b separated from each other by a partition wall 11c. The blower chamber 11a and the machine chamber 11b are aligned in the left-right direction Y, which intersects with the vertical direction Z. A heat exchanger 13 and a blower 15 are disposed inside the blower chamber 11a. A compressor 12, a control unit 17, and a liquid receiver 30 are disposed inside the machine chamber 11b. The machine chamber 11b is located to the right (+Y side) of the blower chamber 11a. The dimension of the machine chamber 11b in the left-right direction Y is smaller than the dimension of the blower chamber 11a in the left-right direction Y. In the first embodiment, the blower chamber 11a corresponds to the "first chamber" and the machine chamber 11b corresponds to the "second chamber."
[0024] Of the walls constituting the housing 11, the wall located on the right side (+Y side) is the opposing wall 11d. The opposing wall 11d is part of the wall constituting the machine room 11b. The opposing wall 11d is a wall arranged opposite the receiver 30 in the left-right direction Y. The opposing wall 11d is located to the right of the compressor 12 and the receiver 30. In the first embodiment, the opposing wall 11d is a side panel whose plate surface faces in the left-right direction Y and extends in the vertical direction Z.
[0025] Within the blower chamber 11a, the blower 15 is located in front of the heat exchanger 13 (+X side). The blower 15 generates an air flow that passes through the heat exchanger 13, and sends the air that has exchanged heat with the refrigerant R to the outside of the outdoor unit 10. The blower 15 draws outdoor air into the housing 11 from the rear side (-X side) of the blower chamber 11a. The air drawn into the housing 11 passes through the heat exchanger 13, exchanging heat with the refrigerant R during this process. The air that has passed through the heat exchanger 13 is blown out to the front side of the blower chamber 11a. In this way, the blower 15 generates an air flow that passes through the heat exchanger 13.
[0026] Within the machine chamber 11b, the compressor 12 is fixed to the upper surface of the bottom 11g of the housing 11. The compressor 12 has a generally cylindrical shape extending in the vertical direction Z. The compressor 12 is located in a lower portion of the front (+X side) and left (-Y side) portion of the interior of the machine chamber 11b. The compressor 12 compresses the refrigerant R flowing through the circulation path 18. The control unit 17 is located in an upper portion of the interior of the machine chamber 11b. At least a portion of the control unit 17 is located to the left (-Y side) of the receiver 30.
[0027] The receiver 30 is fixed to the upper surface of the bottom 11g in the machine room 11b via a support member 11e. The receiver 30 is located above and spaced apart from the upper surface of the bottom 11g. The receiver 30 is located on the right side (+Y side) and rear side (-X side) inside the machine room 11b.
[0028] The lower end of the receiver 30 is located below the upper end of the compressor 12 and above the lower end of the compressor 12. The upper end of the receiver 30 is located above the upper end of the compressor 12. The receiver 30 is located rearward (toward the -X side) of the compressor 12. The right end (+Y side) of the receiver 30 is located to the right of the right end of the compressor 12. The distance in the left-right direction Y between the receiver 30 and the opposing wall 11d is smaller than the distance in the left-right direction Y between the compressor 12 and the opposing wall 11d. The distance in the left-right direction Y between the receiver 30 and the opposing wall 11d is smaller than the distance in the left-right direction Y between the receiver 30 and the partition wall 11c.
[0029] The receiver 30 is capable of storing excess refrigerant R therein. Liquid refrigerant R is stored in the receiver 30. In the first embodiment, the receiver 30 is an accumulator arranged on the low-pressure side of the circulation path 18 where the pressure of the refrigerant R flowing therethrough is relatively low. As shown in FIG. 1 , the receiver 30 is connected to the suction side of the compressor 12.
[0030] The receiver 30 may be any container capable of storing the refrigerant R. The receiver 30 may be, for example, a receiver arranged on the high-pressure side of the circulation path 18 where the pressure of the refrigerant R flowing therethrough is relatively high. Furthermore, when two expansion valves 14 are provided, the receiver 30 may be, for example, a receiver arranged between the two expansion valves 14 in the circulation path 18 and in an intermediate-pressure region where the pressure of the refrigerant R is between a high-pressure region and a low-pressure region.
[0031] As shown in Figure 3, the receiver 30 has a cylindrical container body 31 extending in the vertical direction Z. The container body 31 forms the outer shell of the receiver 30 and is the part where the refrigerant R is stored. The container body 31 is a pressure vessel. The container body 31 is made of, for example, metal. The interior of the container body 31 is the interior of the receiver 30. The container body 31 has a cylindrical member 31a, an upper cover member 31b, and a lower cover member 31c.
[0032] The tubular member 31a is cylindrical and extends in the vertical direction Z, opening on both sides in the vertical direction Z. The upper cover member 31b is a cover member attached to the upper end of the tubular member 31a. The upper cover member 31b is a substantially hemispherical shell-shaped member that opens downward. The upper end of the tubular member 31a is fitted into the lower end of the upper cover member 31b. The upper cover member 31b closes the upper opening of the tubular member 31a. The lower cover member 31c is a cover member attached to the lower end of the tubular member 31a. The lower cover member 31c is a substantially hemispherical shell-shaped member that opens upward. The lower end of the tubular member 31a is fitted into the upper end of the lower cover member 31c. The lower cover member 31c closes the lower opening of the tubular member 31a. In the following description, the radial direction about the central axis of the cylindrical tubular member 31a may be simply referred to as the "radial direction."
[0033] The outdoor unit 10 includes at least one refrigerant pipe 19 through which the refrigerant R flows. In the first embodiment, a plurality of refrigerant pipes 19 are provided. The refrigerant pipes 19 are pipes that form part of the circulation path 18. The plurality of refrigerant pipes 19 are arranged inside the machine chamber 11b. Some of the plurality of refrigerant pipes 19 are located to the left (-Y side) of the receiver 30.
[0034] The plurality of refrigerant pipes 19 include supported pipes 19a supported by supports 40 described below. As shown in Fig. 1 , in the first embodiment, supported pipes 19a are pipes that are connected to pipes extending from indoor unit 20 and that connect to expansion valves 14 in housing 11 of outdoor unit 10. Supported pipes 19a are liquid pipes through which liquid refrigerant R flows. Note that supported pipes 19a may be any of the plurality of refrigerant pipes 19.
[0035] As shown in Figure 3, the supported pipe 19a is arranged to pass between the opposing wall portion 11d and the receiver 30 in the left-right direction Y. The supported pipe 19a has an extension portion 19b that extends in the front-rear direction X. In the first embodiment, the extension portion 19b extends parallel to the front-rear direction X. The extension portion 19b is supported by a support 40 described later, and is held to the receiver 30 via the support 40. Note that the portion of the supported pipe 19a supported by the support 40 described later may extend in any direction as long as it is a portion that is arranged to pass between the opposing wall portion 11d and the receiver 30 in the left-right direction Y.
[0036] The outdoor unit 10 includes a support 40 fixed to the receiver 30. The support 40 is a member for supporting the supported pipe 19a. The support 40 is disposed inside the machine chamber 11b.

As shown in FIG. 8 , in the first embodiment, the rear (−X side) end of the first main body portion 51 is located at approximately the same position in the front-rear direction X as the apex 31d of the tubular member 31a. The apex 31d is the apex of an arc-shaped portion of the tubular member 31a that is convex toward the opposing wall portion 11d when viewed in the vertical direction Z. The apex 31d is the end on the right side (+Y side) of the tubular member 31a. In the first embodiment, the apex 31d is the portion of the tubular member 31a that is located closest to the opposing wall portion 11d in the left-right direction Y. In the first embodiment, the arc-shaped portion of the cylindrical member 31a that is convex toward the opposing wall portion 11d as viewed in the vertical direction Z is the right portion of the cylindrical member 31a, and extends in a semicircular arc shape that is convex toward the right (+Y side) as viewed in the vertical direction Z. The portion of the first main body portion 51 excluding a boundary portion 58 with the second fixing portion 54 is disposed away from the cylindrical member 31a to the right (+Y side).

The first elastic portion 71 and the third elastic portion 73 are attached to the first support component 50 by, for example, an adhesive provided on the surface of the elastic sheet 70a. Note that the method for fixing the first elastic portion 71 and the third elastic portion 73 to the first support component 50 is not particularly limited.
[0067] The first elastic portion 71 is sheet-shaped and extends in a plane (X-Z plane) perpendicular to the left-right direction Y.

A portion of the lower part of the first elastic portion 71 is located between the first main body portion 51 and the extension portion 19b in the left-right direction Y and is compressed and elastically deformed by being pressed to the left (-Y side) by the extension portion 19b. In this way, a portion of the first elastic portion 71 is disposed between the first main body portion 51 and the supported pipe 19a in a state where it is elastically deformed in the left-right direction Y.
[0068] As shown in Fig. 9, the first elastic portion 71 has a generally rectangular shape that is long in the front-rear direction X when viewed in the left-right direction Y. The dimension of the first elastic portion 71 in the front-rear direction X is substantially the same as the dimension of the first main body portion 51 in the front-rear direction X. As shown in Fig. 5, the rear (-X side) end of the first elastic portion 71 is located slightly forward (+X side) of the boundary portion 58 between the first main body portion 51 and the second fixing portion 54. The first elastic portion 71 protrudes rearward (-X side) from the second support component 60.
[0069] The third elastic portion 73 is in the form of a sheet that extends in a plane (X-Y plane) perpendicular to the vertical direction Z. As shown in Fig. 10, the third elastic portion 73 has a generally rectangular shape that is long in the front-rear direction X when viewed in the vertical direction Z. The dimension of the third elastic portion 73 in the front-rear direction X is the same as the dimension of the first elastic portion 71 in the front-rear direction X.
[0070] 7, the third elastic portion 73 is fixed to the upper surface of the bottom wall portion 55. The left end (-Y side) of the third elastic portion 73 is connected to the lower end of the first elastic portion 71. The right end (+Y side) of the third elastic portion 73 is located at approximately the same position as the right end of the bottom wall portion 55 in the left-right direction Y.
[0071] The third elastic portion 73 is located below the extension portion 19b of the supported pipe 19a. At least a portion of the third elastic portion 73 is located between the lower wall portion 55 and the supported pipe 19a in the vertical direction Z. In the first embodiment, almost the entire third elastic portion 73 is located between the lower wall portion 55 and the extension portion 19b in the vertical direction Z. The lower end portion of the extension portion 19b is in contact with the upper surface of the third elastic portion 73. The third elastic portion 73 may be compressed elastically deformed by being pressed downward by the extension portion 19b. The third elastic portion 73 may not be in contact with the extension portion 19b.
[0072] The second elastic portion 72, the fourth elastic portion 74, and the fifth elastic portion 75 are fixed to the second support component 60. The second elastic portion 72 and the fourth elastic portion 74 are attached to the second support component 60 by, for example, an adhesive provided on the surface of the elastic sheet 70b. The fifth elastic portion 75 is attached to the second support component 60 by, for example, an adhesive provided on the surface of the elastic sheet that constitutes the fifth elastic portion 75. Note that the method for fixing the second elastic portion 72, the fourth elastic portion 74, and the fifth elastic portion 75 to the second support component 60 is not particularly limited.
[0073] The second elastic portion 72 is sheet-shaped and extends in a plane (X-Z plane) perpendicular to the left-right direction Y. The second elastic portion 72 is fixed to the left (-Y side) surface of the second main body portion 61. The lower end of the second elastic portion 72 is located below the bottom wall portion 55. The lower end of the second elastic portion 72 is located above and spaced apart from the bent portion 64. The right (+Y side) end of the third elastic portion 73 contacts the left side surface of the second elastic portion 72. The upper end of the second elastic portion 72 contacts the lower surface of the top wall portion 62. The second elastic portion 72 is disposed on the right (+Y side) side of the first elastic portion 71, facing and spaced apart. As shown in FIG. 5 , the second elastic portion 72 is disposed on the right side of the front (+X side) portion of the first elastic portion 71, facing and spaced apart.
[0074] 7, a portion of the lower part of the second elastic member 72 is located between the second main body 61 and the extension 19b in the left-right direction Y, and is compressed and elastically deformed by being pressed to the right by the extension 19b. In this way, the portion of the second elastic member 72 is disposed between the second main body 61 and the supported pipe 19a in a state where it is elastically deformed in the left-right direction Y.
[0075] In the first embodiment, the distance in the left-right direction Y between the first body portion 51 and the second body portion 61 is smaller than the dimension in the left-right direction Y of the portion of the supported pipe 19a sandwiched in the left-right direction Y between the first body portion 51 and the second body portion 61, i.e., the sum of the outer diameter of the extension portion 19b, the dimension in the left-right direction Y of the first elastic portion 71 in an unelastically deformed state, and the dimension in the left-right direction Y of the second elastic portion 72 in an unelastically deformed state. Therefore, by sandwiching the supported pipe 19a in the left-right direction Y between the first body portion 51 to which the first elastic portion 71 is fixed and the second body portion 61 to which the second elastic portion 72 is fixed, the first elastic portion 71 and the second elastic portion 72 are pushed by the supported pipe 19a and elastically deformed. The distance in the left-right direction Y between the first main body portion 51 and the second main body portion 61 is the distance in the left-right direction Y between the right side (+Y side) surface of the first main body portion 51 and the left side (-Y side) surface of the second main body portion 61.
[0076] 12 , the second elastic portion 72 has a rectangular shape when viewed in the left-right direction Y. The dimension of the second elastic portion 72 in the front-rear direction X is substantially the same as the dimension of the second main body portion 61 in the front-rear direction X.
[0077] The fourth elastic portion 74 is in the form of a sheet that extends in a plane (X-Y plane) perpendicular to the vertical direction Z. When viewed in the vertical direction Z, the fourth elastic portion 74 has a rectangular shape that is long in the front-rear direction X. The dimension of the fourth elastic portion 74 in the front-rear direction X is the same as the dimension of the second elastic portion 72 in the front-rear direction X.
[0078] 7, the fourth elastic portion 74 is fixed to the lower surface of the upper wall portion 62. The right end (+Y side) of the fourth elastic portion 74 is connected to the upper end of the second elastic portion 72. The left end (-Y side) of the fourth elastic portion 74 is in contact with the right surface of the first main body portion 51. The left end of the fourth elastic portion 74 is disposed above the first elastic portion 71, facing and spaced apart.
[0079] The fourth elastic portion 74 is located above the extension portion 19b of the supported pipe 19a. At least a portion of the fourth elastic portion 74 is located between the upper wall portion 62 and the supported pipe 19a in the vertical direction Z. In the first embodiment, almost the entire fourth elastic portion 74, excluding the left end portion, is located between the upper wall portion 62 and the extension portion 19b in the vertical direction Z. The fourth elastic portion 74 is located above and spaced apart from the extension portion 19b. The fourth elastic portion 74 may be in contact with the extension portion 19b. The fourth elastic portion 74 may also be pressed upward by the extension portion 19b, thereby undergoing compressive elastic deformation.
[0080] The fifth elastic portion 75 is sheet-shaped and extends in a plane perpendicular to the left-right direction Y (in the X-Y plane). As shown in FIG. 12 , the fifth elastic portion 75 is rectangular when viewed in the left-right direction Y. The dimension of the fifth elastic portion 75 in the front-rear direction X is the same as the dimension of the second elastic portion 72 and the dimension of the fourth elastic portion 74 in the front-rear direction X. As shown in FIG. 7 , the fifth elastic portion 75 is fixed to the right (+Y side) surface of the second main body portion 61. The fifth elastic portion 75 is disposed between the second elastic portion 72 and the second main body portion 61 in the left-right direction Y. The fifth elastic portion 75 is located between the second main body portion 61 and the opposing wall portion 11d in the left-right direction Y. In FIG. 7 , a gap is provided between the fifth elastic portion 75 and the opposing wall portion 11d, and the fifth elastic portion 75 does not contact the opposing wall portion 11d. Note that the fifth elastic portion 75 may contact the opposing wall portion 11d.
[0081] According to the first embodiment, the outdoor unit 10 of the refrigeration cycle apparatus 100 includes a support 40 fixed to the receiver 30. The supported pipe 19a is disposed between the opposing wall 11d and the receiver 30 in the left-right direction Y. The support 40 has a first main body portion 51, a first support component 50 fixed to the receiver 30, and a second main body portion 61 disposed between the first main body portion 51 and the supported pipe 19a in the left-right direction Y. The support 40 also has a second support component 60 fixed to the first support component 50, a first elastic portion 71 at least a portion of which is disposed between the first main body portion 51 and the supported pipe 19a in a state where it is elastically deformed in the left-right direction Y, and a second elastic portion 72 at least a portion of which is disposed between the second main body portion 61 and the supported pipe 19a in a state where it is elastically deformed in the left-right direction Y. Therefore, the first main body portion 51 and the second main body portion 61 can sandwich and hold the supported pipe 19a in the left-right direction Y via each elastic portion. As a result, even if the supported pipe 19a vibrates, the supported pipe 19a can be prevented from hitting the opposing wall portion 11d and the receiver 30, thereby preventing abnormal noise. Therefore, the supported pipe 19a can be passed between the receiver 30 and the opposing wall portion 11d while preventing abnormal noise. Furthermore, because the supported pipe 19a can be prevented from hitting the opposing wall portion 11d and the receiver 30, damage to the supported pipe 19a can be prevented.
[0082] Furthermore, the supported pipes 19a, which are some of the refrigerant pipes 19 among the plurality of refrigerant pipes 19, can be passed between the receiver 30 and the opposing wall 11d in the left-right direction Y, which tends to be relatively narrow, and the space within the machine chamber 11b can be effectively utilized. This prevents the machine chamber 11b from becoming larger, and prevents the outdoor unit 10 from becoming larger. Furthermore, the first elastic portion 71 and the second elastic portion 72 can damp vibrations of the supported pipes 19a, thereby reducing vibrations of the supported pipes 19a.
[0083] According to the first embodiment, the receiver 30 includes a cylindrical tubular member 31a extending in the vertical direction Z. The first support component 50 is fixed to the tubular member 31a. A portion of the supported pipe 19a sandwiched in the left-right direction Y between the first main body portion 51 and the second main body portion 61 is shifted forward (toward the +X side) in the front-rear direction X, which intersects with the vertical direction Z and is perpendicular to the left-right direction Y, with respect to a peak 31d of an arc-shaped portion of the tubular member 31a that is convex toward the opposing wall portion 11d as viewed in the vertical direction Z. The first support component 50 includes a leg portion 52 extending from a front end of the first main body portion 51 to the left (−Y side) in the left-right direction Y, a first fixing portion 53 connected to the left end of the leg portion 52 and fixed to the tubular member 31a, and a second fixing portion 54 connected to a rear end (−X side) of the first main body portion 51 in the front-rear direction X and fixed to the tubular member 31a. In this manner, by using the support 40 to support the portion of the supported pipe 19a that is offset in the front-rear direction X from the top 31d, it is possible to easily fix the second fixing portion 54 to the tubular member 31a without providing another leg between the first main body portion 51 and the second fixing portion 54. This makes it easy to simplify the shape of the first supporting component 50 and to make the first supporting component 50 smaller.
[0084] Furthermore, according to the first embodiment, the second support component 60 is located forward (+X side) of the apex 31d in the front-rear direction X. The second fixing portion 54 has a portion located rearward (-X side) of the apex 31d in the front-rear direction X. Therefore, the second support component 60 can be positioned avoiding the gap between the apex 31d and the opposing wall 11d, which is the narrowest area between the tubular member 31a and the opposing wall 11d. This prevents the second support component 60 from contacting the opposing wall 11d. Therefore, even if the second support component 60 vibrates due to, for example, vibration of the supported pipe 19a being transmitted to the second support component 60, noise generation can be suppressed. Furthermore, the first support component 50 can be positioned between the tubular member 31a and the opposing wall 11d, with the apex 31d straddling the front-rear direction X. Therefore, the supported pipe 19a can be easily held in an appropriate manner even at the apex 31d, which is the narrowest area between the tubular member 31a and the opposing wall 11d. This makes it possible to further prevent the supported pipe 19a from hitting the cylindrical member 31a and the opposing wall portion 11d, and to further prevent abnormal noise from being generated.
[0085] Furthermore, according to the first embodiment, the boundary 58 between the first main body portion 51 and the second fixing portion 54 overlaps the top 31d as viewed in the left-right direction Y. Therefore, as viewed in the vertical direction Z, the first main body portion 51 extends in a tangential direction at the top 31d (the front-rear direction X), and the second fixing portion 54 extends in a curved manner from the top 31d rearward along the outer circumferential surface of the tubular member 31a. This allows the second fixing portion 54 to be suitably fixed to the tubular member 31a without providing any legs between the first main body portion 51 and the second fixing portion 54. This simplifies the shape of the first support component 50 and allows the first support component 50 to be suitably fixed to the receiver 30. Furthermore, the first main body portion 51 can be easily positioned away from the tubular member 31a, except for the boundary 58 with the second fixing portion 54. Therefore, even when the first main body portion 51 vibrates, the first main body portion 51 is prevented from hitting the tubular member 31a, thereby suppressing the generation of abnormal noise.
[0086] Furthermore, according to the first embodiment, the first elastic portion 71 protrudes rearward (toward the −X side) in the front-rear direction X beyond the second support component 60. Therefore, the first elastic portion 71 can prevent the portion of the supported pipe 19a that protrudes rearward beyond the second support component 60 from directly hitting the first support component 50. This further prevents the supported pipe 19a from directly hitting the first support component 50 and generating abnormal noise.
[0087] Furthermore, according to the first embodiment, the first support component 50 has a lower wall portion 55 located below the supported pipe 19a in the vertical direction Z. The support 40 has a third elastic portion 73, at least a portion of which is located between the lower wall portion 55 and the supported pipe 19a in the vertical direction Z. Therefore, the lower wall portion 55 can support the supported pipe 19a from below via the third elastic portion 73. As a result, when the second support component 60 is fixed to the first support component 50, the supported pipe 19a can be supported from below by the lower wall portion 55 and held in place by the first support component 50. This facilitates the task of fixing the second support component 60 to the first support component 50 and clamping the supported pipe 19a. Furthermore, the lower wall portion 55 can prevent the supported pipe 19a from slipping out downward from between the first main body portion 51 and the second main body portion 61. Furthermore, since the third elastic portion 73 is provided, the supported pipe 19a can be prevented from directly hitting the lower wall portion 55, and the generation of abnormal noise can be prevented.
[0088] Furthermore, according to the first embodiment, the second support component 60 has an upper wall portion 62 located above the supported pipe 19a in the vertical direction Z. The support 40 has a fourth elastic portion 74, at least a portion of which is located between the upper wall portion 62 and the supported pipe 19a in the vertical direction Z. Therefore, when the supported pipe 19a moves upward from the position shown in FIG. 7 , the upper wall portion 62 can support the supported pipe 19a from above via the fourth elastic portion 74. This prevents the supported pipe 19a from slipping out upward from between the first main body portion 51 and the second main body portion 61. Furthermore, the provision of the fourth elastic portion 74 prevents the supported pipe 19a from directly hitting the upper wall portion 62, thereby suppressing the generation of abnormal noise.
[0089] Furthermore, according to the first embodiment, the second support component 60 includes a first fixed portion 63 fixed to the first main body portion 51 by a first screw member 81, and a second fixed portion 65 located below the first fixed portion 63 and fixed to the protrusion 56 by a second screw member 82. The second fixed portion 65 is located to the right (+Y side) of the first fixed portion 63. The first screw member 81 is located forward (+X side) of the second screw member 82 in the front-rear direction X. Therefore, the first screw hole 57a into which the first screw member 81 is fastened can be positioned farther away from the top 31d. This allows the first screw hole 57a to be provided in a portion of the first main body portion 51 where the distance between the first screw member 81 and the tubular member 31a in the left-right direction Y is relatively large. Therefore, even when the first fixed portion 63 is fixed to the first main body portion 51 by the first screw member 81, the first screw member 81 can be prevented from hitting the tubular member 31a. On the other hand, by arranging the second fixed portion 65 to the right of the first fixed portion 63, the portion of the first support component 50 to which the second fixed portion 65 is fixed, i.e., the protrusion 56, can be arranged farther away from the tubular member 31a in the left-right direction Y than the first main body portion 51. This prevents the second screw member 82 from hitting the tubular member 31a even when the center of the second fixed portion 65 in the front-rear direction X is fixed to the protrusion 56 by the second screw member 82.
[0090] Furthermore, according to the first embodiment, the second support component 60 has a bent portion 64 that bends from the lower end of the second main body portion 61 to the left (-Y side) in the left-right direction Y. The second fixed portion 65 protrudes downward from the left end of the bent portion 64. Therefore, the second fixed portion 65 can be disposed to the left of the second main body portion 61. As a result, as shown in FIG. 7 , the screw head of the second screw member 82 that fixes the second fixed portion 65 can be disposed below the bent portion 64. Therefore, the screw head of the second screw member 82 can be prevented from protruding to the right (+Y side) of the second main body portion 61. Therefore, the screw head of the second screw member 82 can be prevented from contacting the opposing wall portion 11d.
[0091] Furthermore, according to the first embodiment, the support 40 has a fifth elastic portion 75 fixed to the right (+Y side) surface of the second main body portion 61. The fifth elastic portion 75 is located between the second main body portion 61 and the opposing wall portion 11d in the left-right direction Y. Therefore, even if the support 40 vibrates, the fifth elastic portion 75 can prevent the second support component 60 from directly contacting the opposing wall portion 11d. This further reduces the generation of abnormal noise. Furthermore, because the fifth elastic portion 75 can attenuate vibrations, even if the second support component 60 contacts the opposing wall portion 11d via the fifth elastic portion 75, transmission of vibrations to the opposing wall portion 11d can be prevented.
[0092] Furthermore, according to the first embodiment, the second support component 60 has a hook portion 66 that hooks onto the first support component 50 from above in the vertical direction Z. Therefore, when fixing the second support component 60 to the first support component 50 fixed to the receiver tank 30, the hook portion 66 can be hooked onto the first support component 50 from above, thereby holding the second support component 60 to the first support component 50. This eliminates the need to hold the second support component 60 with one hand, and the work of fixing the second support component 60 to the first support component 50 can be easily performed. In the first embodiment, with the hook portion 66 hooked onto the upper edge of the first main body 51 from above to hold the second support component 60 to the first support component 50, the work of fixing the second support component 60 to the first support component 50 with the first screw member 81 and the second screw member 82 can be easily performed.
[0093] Furthermore, according to the first embodiment, a recess 51a recessed downward is formed at the upper end of the first support component 50 in the vertical direction Z. The hook portion 66 is hooked from above into the recess 51a. Therefore, by hooking the hook portion 66 into the portion of the first support component 50 where the recess 51a is formed, the second support component 60 can be held relative to the first support component 50 in a state where it is positioned to a certain extent. Furthermore, because the hook portion 66 is prevented from moving in the front-rear direction X by both edges of the recess 51a in the front-rear direction X, it is possible to prevent the second support component 60 from shifting relative to the first support component 50 when fixing the second support component 60 to the first support component 50.

In the following description, the same components as those in the above-described embodiment will be denoted by the same reference numerals as appropriate and the description thereof may be omitted.
[0095] As shown in FIG. 13 , in the second embodiment, the support 40 supports two supported pipes 19a. The two supported pipes 19a are arranged with a gap in the vertical direction Z. When the two supported pipes 19a are held by the support 40 in this manner, the lower supported pipe 19a is easily supported from below by the lower wall portion 55 via the third elastic portion 73, and the upper supported pipe 19a is easily supported from above by the upper wall portion 62 via the fourth elastic portion 74. Therefore, each of the two supported pipes 19a can be easily and suitably supported in the vertical direction Z. The other configurations of the outdoor unit 210 are the same as those of the outdoor unit 10 in the first embodiment.

[0097] As shown in FIG. 14 , in the third embodiment, the support 340 supports three supported pipes 19a. The three supported pipes 19a are arranged side by side at intervals in the vertical direction Z. When the three supported pipes 19a are held by the support 340 in this manner, the lowest supported pipe 19a is easily supported from below by the lower wall portion 55 via the third elastic portion 73, and the highest supported pipe 19a is easily supported from above by the upper wall portion 62 via the fourth elastic portion 74. The support 340 has a larger dimension in the vertical direction Z than the support 40 in the first embodiment. The other configurations of the support 340 are similar to those of the support 40 in the first embodiment. The other configurations of the outdoor unit 310 are similar to those of the outdoor unit 10 in the first embodiment.
