[0003] Patent document 1: Unexamined Japanese patent application, first publication no. 2010 - 71 531 Brief description of the invention Problem to be solved by the invention

[0004] In an outdoor unit, such as the one mentioned above, there are cases where a section of refrigerant lines, through which a refrigerant flows, is located below a manifold, as shown in patent document 1. In such a case, however, the outdoor unit tends to become larger in the vertical direction. With regard to the above, routing the section of refrigerant lines between the manifold and a side panel of a housing (an opposite wall) can be considered to prevent the outdoor unit from becoming larger in the vertical direction.However, since the space between the collector and the side of the baffle tends to become narrow, there are concerns that routing the section of refrigerant lines between the collector and the side baffle could generate noise in a case where the refrigerant lines vibrate or the like and touch the collector and / or the side baffle.

[0005] The present disclosure is made with consideration of the above problem, and one of its objectives is to provide an outdoor unit capable of suppressing noise generation caused by the passage of a refrigerant line between a receptacle and an opposite wall of a casing and a receptacle, and to provide a refrigeration circuit device incorporating such an outdoor unit.

[0012] Fig. Figure 1 is a schematic representation showing an overview configuration of a refrigeration circuit unit 100 in a first embodiment. The refrigeration circuit unit 100 is a device with a refrigeration circuit that circulates a refrigerant R. In the present embodiment, the refrigeration circuit unit 100 is an air conditioner. As shown in Figure 1, the refrigeration circuit unit 100 is a refrigeration circuit unit. Fig. As shown in Figure 1, the refrigeration unit 100 comprises an outdoor unit 10, an indoor unit 20 and a circulation path 18.

[0013] The outdoor unit 10 is located outdoors. The indoor unit 20 is located indoors. The outdoor unit 10 and the indoor unit 20 are connected by the circulation path 18, which circulates the refrigerant R. The outdoor unit 10 and the indoor unit 20 are heat exchanger units that perform heat exchange with air. The refrigeration unit 100 is able to regulate the temperature of the air in an indoor space by performing heat exchange between the refrigerant R, which flows in the circulation path 18, and the indoor space in which the indoor unit 20 is located.

[0014] Examples of refrigerant R flowing through circulation path 18 include a fluorine-based refrigerant with a low global warming potential (GWP), a hydrocarbon-based refrigerant, or the like. Refrigerant R can also include, for example, a single refrigerant such as R1234yf, R1234ze, R32, and R290; a blend containing two or more of the aforementioned refrigerants; or a blend containing an additional refrigerant mixed with the aforementioned. For example, refrigerant R can be a blend containing R1132(E) or a blend containing R1123. For example, a refrigerant R could be a combination of R516A, R445A, R444A, R454C, R444B, R454A, R455A, R457A, R459B, R452B, R454B, R447B, R447A, R446A and R459A.The density of the refrigerant R in a gaseous state is greater than the density of air.

[0015] The outdoor unit 10 comprises a housing 11, a compressor 12, a heat exchanger 13, an expansion valve 14, a fan 15, a four-way valve 16, a controller 17, and a receiver 30. The compressor 12, the heat exchanger 13, the expansion valve 14, the fan 15, the four-way valve 16, the controller 17, and the receiver 30 are housed within the housing 11. The controller 17 controls various parts of the outdoor unit 10. For example, the controller 17 is a system controller that manages the operation of the entire refrigeration circuit unit 100.

[0016] The compressor 12, the heat exchanger 13, the flow expansion valve 14, the four-way valve 16, and the inlet 30 are connected to the circulation path 18 by a section located inside the housing 11.

[0017] The four-way valve 16 is provided in a section of the circulation path 18 that is connected to a discharge side of the compressor 12. By replacing a section of the circulation path 18, the four-way valve 16 can reverse the flow direction of the refrigerant R in the circulation path 18. If the path connected by the four-way valve 16 is the path of the four-way valve 16 that is in Fig. As shown by solid lines 1, the refrigerant R flows in circulation path 18 in the direction indicated in Fig. 1 is shown by the arrow in a solid line. Otherwise, if the path connected by the four-way valve 16 is the path of the four-way valve 16 that is in Fig. As shown by the dashed lines in 1, the refrigerant R flows in circulation path 18 in the direction indicated in Fig. 1 is shown by the arrow in a dashed line.

[0018] The indoor unit 20 comprises a housing 21, a heat exchanger 22, and a fan 23. The heat exchanger 22 and the fan 23 are housed within the interior of the housing 21. The indoor unit 20 can operate in cooling mode, cooling the indoor air in which the indoor unit 20 is located, and in heating mode, heating the indoor air in which the indoor unit 20 is located.

[0019] When the indoor unit 20 is operated in cooling mode, the refrigerant R, which flows in the circulation path 18, flows in the direction indicated in Fig. 1 is shown by solid lines. In other words, when the indoor unit 20 is operating in cooling mode, the refrigerant R, which flows in the circulation path 18, circulates so that it returns to the compressor 12 after passing 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 intake 30 in that order. During cooling operation, the heat exchanger 13 inside the outdoor unit 10 acts as a condenser, and the heat exchanger 22 inside the indoor unit 20 acts as an evaporator.

[0020] Otherwise, if the indoor unit 20 is operated in heating mode, the refrigerant R flowing in circulation path 18 flows in the direction indicated in Fig. 1 is shown by dashed lines. In other words, when the indoor unit 20 is operating in heating mode, the refrigerant R, which flows in the circulation path 18, circulates so that it returns to the compressor 12 after passing 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 intake 30 in that order. During heating operation, the heat exchanger 13 inside the outdoor unit 10 acts as the evaporator, and the heat exchanger 22 inside the indoor unit 20 acts as the condenser.

[0021] Next, the outdoor unit 10 of the first embodiment will be explained in detail. Fig. Figure 2 is a perspective view showing the outdoor unit 10. Fig. Figure 3 is a perspective view showing part of outdoor unit 10. Fig. 3 is part of the housing 11 omitted. As in Fig. As shown in Figure 2, the housing 11 is a quasi-rectangular (semi-square) container, which has surfaces that are each facing the front-back direction X, the left-right direction Y and the vertical direction Z.

[0022] As in Fig. As shown in Figure 3, the housing 11 comprises a blower compartment 11a and a mechanical compartment 11b, which are separated from each other by a partition 11c. The blower compartment 11a and the mechanical compartment 11b are oriented such that they are adjacent to each other in the left-right direction Y, which intersects the vertical direction Z. The heat exchanger 13 and the blower 15 are arranged in an interior of the blower compartment 11a. The compressor 12, the control unit 17, and the intake 30 are arranged in an interior of the mechanical compartment 11b. The mechanical compartment 11b is located to the right (+Y-side) of the blower compartment 11a. One dimension of the mechanics chamber 11b in the left-right direction Y is smaller than one dimension of the blower chamber 11a in the left-right direction Y. In the first embodiment, the blower chamber 11a corresponds to a "first chamber" and the mechanics chamber 11b to a "second chamber".

[0023] A wall located to the right (+Y-side) of the walls forming the housing 11 is an opposing wall 11d. The opposing wall 11d is part of the wall that forms the mechanics compartment 11b. The opposing wall 11d is the wall positioned so that it faces the receptacle 30 in the left-right direction Y. The opposing wall 11d is located to the right of the compressor 12 and the receptacle 30. In the first embodiment, the opposing wall 11d is a side-face panel having a plate surface facing the left-right direction Y and extending in the vertical direction Z.

[0024] The blower 15 is located inside the blower compartment 11a at the front (+X-side) of the heat exchanger 13. The blower 15 generates an airflow that passes through the heat exchanger 13, and after heat exchange with the refrigerant R, the air is discharged from the outdoor unit 10. The blower 15 draws outside air from the rear (-X-side) of the blower compartment 11a into the interior of the housing 11. Air drawn into the interior of the housing 11 undergoes heat exchange with the refrigerant R as it passes through the heat exchanger 13. Air that has passed through the heat exchanger 13 is discharged from the front of the blower compartment 11a. Thus, the blower 15 generates the airflow that passes through the heat exchanger 13.

[0025] The compressor 12 is mounted inside the mechanical compartment 11b on the upper surface of a base 11g of the housing 11. The compressor 12 is a semi-cylinder extending in the vertical direction Z. Within the mechanical compartment 11b, the compressor 12 is located in a lower section at the front (+X-side) and on the left (-Y-side). The compressor 12 compresses the refrigerant R flowing within the circulation path 18. The control unit 17 is located in an upper section within the mechanical compartment 11b. At least part of the control unit 17 is located further to the left (-Y-side) than the receiver 30.

[0026] The mounting 30 is attached to the upper surface of the base 11g inside the mechanics chamber 11b via a support element 11e. The mounting 30 is positioned at a distance above the upper surface of the base 11g. The mounting 30 is located in a section that extends to the right (+Y-side) and rear (-X-side) inside the mechanics chamber 11b.

[0027] A lower end of the inlet 30 is located further down than an upper end of the compressor 12 and is located further up than a lower end of the compressor 12. An upper end of the inlet 30 is located further up than the upper end of the compressor 12. The inlet 30 is located further back (-X-side) than the compressor 12. A right (+Y-side) end of the inlet 30 is located further to the right than a right end of the compressor 12. A distance between the inlet 30 and the opposite wall 11d in the left-right direction Y is less than a distance between the compressor 12 and the opposite wall 11d in the left-right direction Y. The distance between the inlet 30 and the opposite wall 11d in the left-right direction Y is less than a distance between the inlet 30 and the partition 11c in the left-right direction Y.

[0028] The intake 30 is capable of storing excess refrigerant R inside it. The refrigerant R is stored in a liquid state inside the intake 30. In the first embodiment, the intake 30 is a collector located on the low-pressure side of the circulation path 18, where the refrigerant R flowing therein has a relatively low pressure. As in Fig. As shown in Figure 1, the inlet 30 is connected to an intake side of the compressor 12.

[0029] As long as the receptacle 30 is a container capable of storing the refrigerant R inside, the receptacle 30 can be any type of container. For example, the receptacle 30 can be located on a high-pressure side of the circulation path 18, where the refrigerant R flowing therein has a relatively high pressure. If two expansion valves 14 are provided, the receptacle 30 can, for example, be located between the two expansion valves 14 of the circulation path 18 and in an intermediate pressure region, where the pressure of the refrigerant R lies between a high-pressure region and a low-pressure region.

[0030] As in Fig. As shown in Figure 3, the receptacle 30 comprises a cylindrical vessel body 31 extending in the vertical direction Z. The vessel body 31 forms an outer shell of the receptacle 30 and is a part in which the refrigerant R is stored. The vessel body 31 is a pressure vessel. The vessel body 31 is, for example, made of a metal. The interior of the vessel body 31 is the interior of the receptacle 30. The vessel body 31 comprises a cylindrical element 31a, an upper cover element 31b, and a lower cover element 31c.

[0031] The cylindrical element 31a is a cylinder extending in the vertical direction Z and open at both ends in the vertical direction Z. The upper cover element 31b is a cover element attached to an upper end of the cylindrical element 31a. The upper cover element 31b is a semicircular shell element that opens towards the bottom. An inner surface of the lower end of the upper cover element 31b is attached to an upper end of the cylindrical element 31a. The upper cover element 31b closes the opening at the top of the cylindrical element 31a. The lower cover element 31c is a cover element attached to the lower end of the cylindrical element 31a. The lower cover element 31c is a semicircular shell element that opens upwards. The lower end of the cylindrical element 31a is located inside an upper end of the lower cover element 31c.The lower cover element 31c closes the lower opening of the cylindrical element 31a. In the following explanations, there are cases in which a radial direction with a center which is the central axis of the cylindrical element 31a is referred to as a "radial direction".

[0032] The outdoor unit 10 comprises at least one refrigerant line 19 through which the refrigerant R flows. In the first embodiment, several refrigerant lines 19 are provided. The refrigerant line 19 is arranged such that it forms a section of the circulation path 18. Several refrigerant lines 19 are arranged inside the mechanical compartment 11b. Some of the multiple refrigerant lines 19 are located further to the left (-Y side) than the mounting 30.

[0033] The multiple refrigerant lines 19 comprise a bracket 40, which will be mentioned later, and the supported line 19a, which is held by the bracket 40. As in Fig. As shown in Figure 1, the supported line 19a in the first embodiment is connected to lines extending from the indoor unit 20 and to lines connected to the expansion valve 14 inside the housing 11 of the outdoor unit 10. The supported line 19a is a liquid line, and the refrigerant R flows in it in a liquid state. The supported line 19a can be any one of the refrigerant lines 19 that make up the multiple refrigerant lines 19.

[0034] As in Fig. As shown in Figure 3, the supported conduit 19a is arranged such that it passes between the opposite wall 11d and the receptacle 30 in the left-right direction Y. The supported conduit 19a includes a section extending in the front-back direction X. In the first embodiment, the section 19b extends horizontally in the front-back direction X. The section 19b is supported by the bracket 40, which will be mentioned later, and is held by the bracket 40 on the receptacle 30. As long as a section of the supported conduit 19a held by the bracket 40 is arranged such that it passes between the opposite wall 11d and the receptacle 30 in the left-right direction Y, the section 19b can extend in any shape or form.

[0035] The outdoor unit 10 includes the bracket 40, which is attached to the receptacle 30. The bracket 40 is an element for holding the cable 19a. The bracket 40 is located inside the mechanical compartment 11b. Fig. Figure 4 is a perspective view showing part of the recording 30, part of the held line 19a and the bracket 40.

[0036] As in Fig. 4 to Fig. As shown in Figure 9, the bracket 40 comprises a first bracket part 50, which is attached to the receptacle 30, and a second bracket part 60, which, together with the first bracket part 50, encloses the supported line 19a in the left-right direction Y between them. In the first embodiment, both the first bracket part 50 and the second bracket part 60 are sheet metal elements. The first bracket part 50 and the second bracket part 60 are attached to one another. The first bracket part 50 and the second bracket part 60 are attached to one another using a first threaded member 81 and a second threaded member 82.

[0038] The first principal body 51 is a plate having a surface facing the left-right direction Y. In the first embodiment, the first principal body 51 is a semi-rectangle when viewed from the left-right direction Y. As in Fig. As shown in Figure 7, the first main body 51 is a part which, together with the second mounting part 60, encloses the held line 19a in the left-right direction Y between them. As shown in Fig. As shown in Figure 8, in the first embodiment, a rear (X-side) end of the first main body 51 is located approximately at the same position in the front-back direction X as the top 31d of the cylindrical element 31a. The top 31d is the upper end / summit of the portion of the cylindrical element 31a that projects outwards and, viewed in the vertical direction Z, forms an arc projecting towards the opposite wall 11d. The top 31d is a right (+Y-side) end of the cylindrical element 31a. In the first embodiment, the top 31d is located at the point on the cylindrical element 31a closest to the opposite wall 11d in the left-right direction Y.In the first embodiment, the arc projecting from the cylindrical element 31a towards the opposite wall 11d, when viewed from the vertical direction Z, is a right-hand portion of the cylindrical element 31a and extends as a semicircular arc projecting to the right (+Y-side). Parts of the first main body 51, except for the second fixing element 54 and a boundary region 58, are arranged separately from the right (+Y-side) side of the cylindrical element 31a.

[0039] As in Fig. As shown in Figure 10, a first screw hole 57a is formed on the first main body 51. In the first embodiment, the first screw hole 57a is located on the front (+X-side) and top of the first main body 51. As shown in Fig. As shown in Figure 7, the first screw element 81 is attached to the first screw hole 57a. The first screw hole 57a consists of a hole that penetrates the first main body 51 in the left-right direction Y and a cylindrical ridge 57c that projects from the left (-Y-side) side of a circumferential edge of the hole. The ridge 57c projects to the left from a right face of the first main body 51. The first screw element 81 penetrates the ridge 57c in the left-right direction Y and projects further to the left than the ridge 57c. In the first embodiment, threads are formed on an inner surface of the first screw hole 57a when the first screw element 81, which is a self-tapping screw, is attached to it.

In the first embodiment, the leg 52 is a plate having a surface facing the front-back direction X. The leg 52 is a quasi-rectangle that is longer in the vertical direction Z when viewed from the front-back direction X. In the first embodiment, a dimension of the leg 52 in the vertical direction Z is approximately the same as a dimension of the first main body 51 in the vertical direction Z. As shown in Figure 10, the leg 52 is a plate with a surface facing the front-back direction X. Fig. As shown in Figure 11, in the first embodiment the leg 52 curves from the front end of the first main body 51 at a right angle to the left.

[0041] The first fixing element 53 is connected to a left (-Y-side) end of the leg 52. In the first embodiment, the first fixing element 53 extends from the left end of the leg 52 to the left and forward (+X-side) when viewed from the vertical direction Z.

As in Fig. As shown in Figure 9, the first fixing element 53 is a plate that is longer in the vertical direction Z and has a surface that curves along the outer circumferential surface of the cylindrical element 31a. In the first embodiment, a dimension of the first fixing element 53 in the vertical direction Z is the same as a dimension of the leg 52 in the vertical direction Z. A radially inner surface of the first fixing element 53 contacts the outer circumferential surface of the cylindrical element 31a. In the first embodiment, the first fixing element 53 is attached to the cylindrical element 31a by welding. However, the manner in which the first fixing element 53 is attached to the cylindrical element 31a is not particularly restricted.

[0042] The second fixing element 54 is connected to a rear (X-side) end of the first main body 51. The second fixing element 54 projects rearward from the rear end of the first main body 51. Viewed from the vertical direction Z, the second fixing element 54 extends as an arc along the outer circumferential surface of the cylindrical element 31a. The second fixing element 54 is a plate that is longer in the vertical direction Z and has a surface that curves along the outer circumferential surface of the cylindrical element 31a. In the first embodiment, the second fixing element 54 curves more to the left (Y-side) the further it extends rearward.

[0043] A dimension of the second fixing element 54 in the vertical direction Z is approximately the same as a dimension of the first main body 51 in the vertical direction Z. A radially inner surface of the second fixing element 54 contacts the cylindrical element 31a. In the present embodiment, the second fixing element 54 is attached to the cylindrical element 31a by welding. However, the manner in which the second fixing element 54 is attached to the cylindrical element 31a is not limited.

[0044] As in Fig. As shown in Figure 8, a front (+X-side) end of the second fixing element 54 contacts an outer circumferential surface of the top 31d. In the first embodiment, the boundary region 58 of the first main body 51 and the second fixing element 54 overlaps the top 31d when viewed from the left-right direction Y. In other words, the boundary region 58 is located at the same position in the front-back direction X as the top 31d. The boundary region 58 contacts the outer circumferential surface of the top 31d. Except for a portion at one of its front ends, the remaining portions of the second fixing element 54 are located further back (-X-side) than the top 31d.

[0050] As in Fig. As shown in Figure 8, the second mounting part 60 is located on the right side (+Y-side) of the first mounting part 50. The second mounting part 60 is located further forward (+X-side) than the top 31d of the cylindrical element 31a. Fig. Figure 12 is a perspective exploded view showing the second support part 60, which will be mentioned later, a second elastic part 72, which will be mentioned later, a fourth elastic part 74, and a fifth elastic part 75.

As shown in Figure 4, the upper wall 62 is located above the extension 19b. Fig. As shown in Figure 7, the upper wall 62 is located at a distance above the lower wall 55. The lower wall 55 and the upper wall 62 are arranged such that they enclose the extension 19b of the supported conduit 19a in the vertical direction Z between them. The distance between the lower wall 55 and the upper wall 62 in the vertical direction Z is greater than the outer diameter of the supported conduit 19a.

[0055] The first fastening element 63 projects upwards from a left (Y-side) end of the upper wall 62. In the first embodiment, the first fastening element 63 is a plate having a surface facing the left-right direction Y. As in Fig. As shown in Figure 4, the first fastening element 63 is a quasi-rectangle that is longer in the front-back direction X when viewed from the left-right direction Y.

A left face of the first fastening element 63 touches a front (+X-side) section of a right (+Y-side) face of the first main body 51.

[0056] As in Fig. As shown in Figure 9, a first through-hole 67a is formed in the first fastening part 63, which penetrates the first fastening part 63 in the left-right direction Y. In the first embodiment, the first through-hole 67a is a circular hole. The first through-hole 67a is formed at a front (+X-side) end of the first fastening part 63. The first screw element 81 is inserted through the first through-hole 67a from the left (+Y-side) side. The first screw element 81, inserted through the first through-hole 67a, is fastened to the first screw hole 57a formed in the first main body 51. Accordingly, the first fastening part 63 is fastened to the first main body 51 using the first screw element 81.

[0058] The second fastening element 65 projects downwards from the left (-Y-side) end of the bend 64. In the first embodiment, the second fastening element 65 is a plate having a surface facing the left-right direction Y. The second fastening element 65 is a quasi-rectangle that is longer in the front-back direction X when viewed from the left-right direction Y. One dimension of the second fastening element 65 in the front-back direction X is the same as the dimension of the bend 64 in the front-back direction X. The second fastening element 65 is located further down than the first fastening element 63. The second fastening element 65 is located further to the right (+Y-side) than the first fastening element 63. As in Fig. As shown in Figure 9, a dimension of the second fastening part 65 in the front-back direction X is larger than a dimension of the projection 56 in the front-back direction X. A section of a left surface of the second fastening part 65 touches a right surface of the projection 56.

[0059] A second through-hole 67b, which penetrates the second fastening part 65 in the left-right direction Y, is formed in the second fastening part 65. In the first embodiment, the second through-hole 67b is a circular hole. The second through-hole 67b is formed in the front-back direction X in the center of the second fastening part 65. The second through-hole 67b is located below the first through-hole 67a. The second through-hole 67b is located further back (-X-side) and further to the right (+Y-side) than the first through-hole 67a.

[0060] The second screw element 82 is inserted from the right (+Y-side) through the second through-hole 67b. The second through-hole 67b, through which the second screw element 82 was inserted from the right side, is attached to the second screw hole 57b formed on the projection 56. Accordingly, the second fastening part 65 is attached to the projection 56 using the second screw element 82. Thus, in the first embodiment, the second mounting part 60 is attached to the first mounting part 50 by attaching the first mounting part 63 to the first main body 51 using the first screw element 81 and by attaching the second mounting part 65 to the projection 56 using the second screw element 82.

[0061] In the first embodiment, the first screw element 81 is located further forward (+X-side) than the second screw element 82, as shown in Fig. 6 shown. As in Fig. As shown in Figure 7, a screw head of the first screw element 81 is located above the upper wall 62. The screw head of the first screw element 81 is located further to the left (-Y-side) than the second main body 61. A screw head of the second screw element 82 is located below the bend 64. A right (+Y-side) end face of the screw head of the second screw element 82 is located at the same position as a right face of the second main body 61 in the left-right direction Y.

[0062] As in Fig. As shown in Figure 12, a hook 66 is formed at an upper end of the first fastening part 63. The hook 66 projects to the left (-Y side) and downwards from the upper end of the first fastening part 63. The hook 66 extends in the front-back direction X. A dimension of the hook 66 in the front-back direction X is smaller than a dimension of the first fastening part 63 in the front-back direction X. A center point of the hook 66 in the front-back direction X is located at the same position as a center point of the first fastening part 63 in the front-back direction X. As shown in Fig. 5 and Fig. As shown in Figure 7, the hook 66 is engaged in the vertical direction Z from above on the first mounting part 50. In the first embodiment, the hook 66 is engaged in the recess 51a from above. The dimension of the hook 66 in the front-right direction X is smaller than a dimension of the recess 51a in the front-back direction X.

[0063] As in Fig. As shown in Figure 7, the support 40 comprises the first elastic part 71, the second elastic part 72, the third elastic part 73, the fourth elastic part 74, and the fifth elastic part 75. In the first embodiment, the first elastic part 71, the second elastic part 72, the third elastic part 73, the fourth elastic part 74, and the fifth elastic part 75 are sponge elements. The first elastic element 71, the second elastic element 72, the third elastic element 73, the fourth elastic element 74, and the fifth elastic element 75 are each formed as sheets. In the first embodiment, the first elastic part 71 and the third elastic part 73 are integrally formed. Both the first elastic part 71 and the third elastic part 73 are formed by bending an elastic sheet 70a, which is a single sponge-shaped sheet.In the first embodiment, the second elastic part 72 and the fourth elastic part 74 are integrally formed. Both the second elastic part 72 and the fourth elastic part 74 are formed by bending an elastic sheet structure 70b, which is a single sponge-shaped sheet structure.

[0064] As long as the first elastic part 71, the second elastic part 72, the third elastic part 73, the fourth elastic part 74, and the fifth elastic part 75 are elastic bodies, the aforementioned elastic parts can be made of any material. For example, the first elastic part 71, the second elastic part 72, the third elastic part 73, the fourth elastic part 74, and the fifth elastic part 75 can be made of rubber.

[0065] The first elastic part 71 and the third elastic part 73 are attached to the first support part 50. For example, the first elastic part 71 and the third elastic part 73 are attached to the first support part 50 using an adhesive applied to a surface of the elastic sheet structure 70a. The method by which the first elastic part 71 and the third elastic part 73 are attached to the first support part 50 is not particularly restricted.

[0066] The first elastic part 71 is a planar structure extending within a region (within the XZ region) that is orthogonal to the left-right direction Y. The first elastic part 71 is attached to a right (+Y-side) face of the first main body 51. An upper end of the first elastic part 71 is located further below the first screw hole 57a and the upper wall 62. A lower end of the first elastic part 71 touches a top surface of the lower wall 55. A section at the lower part of the first elastic part 71 is located between the first main body 51 and the extension 19b in the left-right direction Y and is compressed by extension 19b such that it compressively deforms towards the right (-Y-side).Accordingly, a section of the first elastic part 71 between the first main body 51 and the supported line 19a is arranged in a state in which it is elastically deformed in the left-right direction Y.

[0067] As in Fig. As shown in Figure 9, the first elastic part 71 is a quasi-rectangle that is longer in the front-back direction X when viewed from the left-right direction Y. A dimension of the first elastic part 71 in the front-back direction X is approximately the same as a dimension of the first principal body 51 in the front-back direction X. As shown in Fig. As shown in Figure 5, a rear (-X-side) end of the first elastic part 71 is located slightly further forward (+X-side) than the first main body 51, the second fixing element 54, and the boundary area 58. The first elastic part 71 projects further rearward (-X-side) than the second mounting part 60.

[0068] The third elastic part 73 is a planar structure that extends within a region (within the XY region) that is orthogonal to the vertical direction Z. As in Fig. As shown in Figure 10, the third elastic part 73 is a quasi-rectangle that is longer in the front-back direction X when viewed from the vertical direction Z. One dimension of the third elastic part 73 in the front-back direction X is the same as the dimension of the first elastic part 71 in the front-back direction X.

[0069] As in Fig. As shown in Figure 7, the third elastic part 73 is attached to a top surface of the lower wall 55. A left (-Y-side) end of the third elastic part 73 is connected to a lower end of the first elastic part 71. A right (+Y-side) end of the third elastic part 73 is located in the left-right direction Y approximately at the same position as a right end of the lower wall 55.

[0070] The third elastic part 73 is located below the extension 19b of the refrigerant lines 19. At least a portion of the third elastic part 73 is located in the vertical direction Z between the lower wall 55 and the supported line 19a. In the first embodiment, almost the entirety of the third elastic part 73 is located between the lower wall 55 and the extension 19b. A lower end of the extension 19b is in contact with a top surface of the third elastic part 73. The third elastic part 73 is pressed downwards by the extension 19b to compress and deform. The third elastic part 73 does not necessarily have to touch the extension 19b.

[0071] The second elastic part 72, the fourth elastic part 74, and the fifth elastic part 75 are attached to the second support part 60. For example, the second elastic part 72 and the fourth elastic part 74 are attached to the second support part 60 using an adhesive applied to a surface of the elastic sheet structure 70b. For example, the fifth elastic part 75 is attached to the second support part 60 using an adhesive applied to a surface of an elastic sheet structure that forms the fifth elastic part 75. However, the manner in which the second elastic part 72, the fourth elastic part 74, and the fifth elastic part 75 are attached to the second support part 60 is not limited.

[0072] The second elastic part 72 is a planar structure that extends within a region (within the XZ region) that is orthogonal to the left-right direction Y. The second elastic part 72 is attached to a left (-Y-side) surface of the second main body 61. A lower end of the second elastic part 72 is located further below the lower wall 55. The lower end of the second elastic part 72 is located spaced above the bend 64. A left surface of the second elastic part 72 touches the right (+Y-side) surface of the third elastic part 73. An upper end of the second elastic part 72 touches a lower surface of the upper wall 62. The second elastic part 72 is positioned such that it faces the right (+Y-side) surface of the first elastic part 71 with a space between them. As in Fig. As shown in Figure 5, the second elastic part 72 is arranged in particular such that it faces the right side of the front (+X-sided) part of the first elastic part 71.

[0073] As in Fig. As shown in Figure 7, a portion of the second elastic part 72 is located in the left-right direction Y between the second main body 61 and the extension 19b and is compressed to the right by the extension 19b, causing it to deform compressively. Accordingly, a portion of the second elastic part 72 between the second main body 61 and the supported conduit 19a is in a state where it is elastically deformed in the left-right direction Y.

[0074] In the first embodiment, the distance between the first main body 51 and the second main body 61 in the left-right direction Y is less than the sum of a dimension in the left-right direction Y of a part enclosed between the first main body 51 and the second main body 61 in the left-right direction Y of the held conduit 19a, in other words less than the sum of an outer diameter of the extension 19b, a dimension of the first elastic part 71 in the left-right direction Y in a state in which it is not elastically deformed, and a dimension of the second elastic part 72 in the left-right direction Y in a state in which it is not elastically deformed.By clamping the held conductor 19a in the left-right direction Y using the first main body 51, to which the first elastic part 71 is attached, and using the second main body 61, to which the second elastic part 72 is attached, the first elastic part 71 and the second elastic part 72 are pressed in by the held conductor 19a such that they deform elastically. A gap between the first main body 51 and the second main body 61 in the left-right direction Y is a gap between a right (+Y-side) surface of the first main body 51 and a left (-Y-side) surface of the second main body 61 in the left-right direction Y.

[0075] As in Fig. As shown in Figure 12, the second elastic part 72 is a rectangle when viewed from the left-right direction Y. A dimension of the second elastic part 72 in the front-back direction X is approximately the same as a dimension of the second main body 61 in the front-back direction X.

[0076] The fourth elastic part 74 is a planar structure that extends within a region (within the XY region) that is orthogonal to the vertical direction Z. The fourth elastic part 74 is a rectangle that is longer in the front-to-back direction X when viewed from the vertical direction Z. A dimension of the fourth elastic part 74 in the front-to-back direction X is the same as a dimension of the second elastic element 72 in the front-to-back direction X.

[0077] As in Fig. As shown in Figure 7, the fourth elastic part 74 is attached to the lower surface of the upper wall 62. A right (+Y-side) end of the elastic part 74 is connected to the upper end of the second elastic part 72. A left (-Y-side) end of the fourth elastic part 74 touches the right surface of the first main body 51. The left end of the fourth elastic part 74 is positioned so that it faces the upper end of the first elastic part 71 with a gap between them.

[0078] The fourth elastic part 74 is located above the extension 19b of the refrigerant lines 19. At least a portion of the fourth elastic part 74 is located in the vertical direction Z between the upper wall 62 and the supported line 19a. In the first embodiment, almost the entirety of the fourth elastic part 74, except for its left end, is located in the vertical direction Z between the upper wall 62 and the extension 19b. The fourth elastic part 74 is arranged separately from and above the extension 19b. The fourth elastic part 74 can contact the extension 19b. The fourth elastic part 74 can be pressed down by the extension 19b from above to compress and deform.

[0079] The fifth elastic part 75 is a planar structure that extends within a region (within the XY region) that is orthogonal to the left-right direction Y. As in Fig. As shown in Figure 12, the fifth elastic part 75 is a rectangle when viewed from the left-right direction Y. A dimension of the fifth elastic part 75 in the front-back direction X is the same as a dimension of the second elastic part 72 in the front-back direction X and a dimension of the fourth elastic part 74 in the front-back direction X. ... Fig. As shown in Figure 7, the fifth elastic part 75 is attached to a right (+Y-side) surface of the second main body 61. The fifth elastic part 75 is arranged such that, together with the second elastic part 72, it encloses the second main body 61 in the left-right direction Y. The fifth elastic part 75 is located in the left-right direction Y between the second main body 61 and the opposite wall 11d. Fig. A space is provided between the fifth elastic part 75 and the opposite wall 11d, such that the fifth elastic part 75 and the opposite wall 11d are not in contact with each other. The fifth elastic part 75 and the opposite wall 11d may touch each other.

[0080] According to the first embodiment, the outdoor unit 10 of the refrigeration unit 100 includes the bracket 40, which is attached to the receptacle 30. The supported line 19a is arranged such that it passes in the left-right direction Y between the opposite wall 11d and the receptacle 30. The bracket 40 comprises the first main body 51, the first support part 50 attached to the receptacle 30, and the second main body 61, which, together with the first main body 51, encloses the supported line 19a in the left-right direction Y between them.The support 40 also includes the second support part 60, which is attached to the first support part 50, the first elastic part 71, at least part of which is elastically deformed in the left-right direction Y between the first main body 51 and the supported conduit 19a, and the second elastic part 72, at least part of which is elastically deformed in the left-right direction Y between the second main body 61 and the supported conduit 19a. Therefore, it is possible to support the supported conduit 19a by sandwiching it between the elastic elements of the first main body 51 and the second main body 61 in the left-right direction Y.Accordingly, even if the supported cable 19a vibrates, it is possible to prevent it from colliding with the opposite wall 11d and the receptacle 30, thus suppressing noise generation. Therefore, it is possible to insert the supported cable 19a between the receptacle 30 and the opposite wall 11d, thereby suppressing noise generation. Since it is possible to prevent the supported cable 19a from colliding with the opposite wall 11d and the receptacle 30, damage to the supported cable 19a can be prevented.

[0081] Since the supported line 19a, which is part of the refrigerant line 19 of the several refrigerant lines 19, is inserted between the intake 30, which narrows relatively slightly, and the opposite wall 11d in the left-right direction Y, it is possible to make good use of the space inside the mechanics room 11b. Accordingly, it is possible to avoid enlarging the mechanics room 11b, and it is possible to avoid enlarging the outdoor unit 10. Since it is also possible to dampen vibrations of the supported lines 19a using the first elastic part 71 and the second elastic part 72, it is possible to reduce vibrations of the supported line 19a.

[0082] According to the first embodiment, the receptacle 30 comprises the cylindrical element 31a, which is a cylinder extending in the vertical direction Z. The first support part 50 is attached to the cylindrical element 31a. A portion of the supported conduit 19a, located in the left-right direction Y between the first main body 51 and the second main body 61, is positioned such that it is offset from a portion of the arc of the cylindrical element 31a, projecting from the vertical direction Z towards the opposite wall 11d, relative to the top 31d in the direction of the front (+X-side) of the front-back direction X, which intersects the vertical direction Z and the left-right direction Y.The first retaining part 50 comprises the leg 52, which extends from a front end of the first main body 51 in the left-right direction Y to the left (-Y-side), the first fixing element 53, which is connected to a left end of the leg 52 and which is attached to the cylindrical element 31a, and the second fixing element 54, which is connected to the rear (-X-side) end of the first main body 51 in the front-back direction X and which is attached to the cylindrical element 31a. As such, by means of a construction in which a part of the held line 19a, which is offset in the front-back direction X with respect to the top 31d, is held by the holder 40, it is possible to simply attach the second fixing element 54 to the cylindrical element 31a without having to provide a separate leg between the first main body 51 and the second fixing element 54.Accordingly, it is easy to simplify the shape of the first bracket part 50, and it is easy to reduce the size of the first bracket part 50.

[0083] According to the first embodiment, the second mounting element 60 is located further forward (+X-side) than the top 31d in the front-back direction X. The second fixing element 54 includes a portion located further backward (-X-side) than the top 31d in the front-back direction X. This prevents the second mounting element 60 from being positioned between the top 31d and the opposite wall 11d, which would otherwise be the narrowest part of the space between the cylindrical element 31a and the opposite wall 11d. Consequently, contact between the second mounting element 60 and the opposite wall 11d is prevented. Therefore, even if the second mounting element 60 vibrates due to vibrations of the supported conduit 19a transmitted to the second mounting element 60, noise generation is suppressed.The first support element 50 is positioned between the cylindrical element 31a and the opposite wall 11d such that it spans the top of the 31d in the front-to-back direction X. As such, even at the top of the 31d, where the space between the cylindrical element 31a and the opposite wall 11d becomes slightly narrower, it is possible to securely hold the supported conduit 19a. Accordingly, it is possible to prevent the supported conduit 19a from colliding with the cylindrical element 31a and / or the opposite wall 11d, and to prevent the generation of noise.

[0084] According to the first embodiment, the boundary region 58 of the first main body 51 and the second fixing element 54 overlaps with the top 31d, viewed from the left-right direction Y. As such, the first main body 51 extends along the top 31d in a tangential direction (front-back direction X) when viewed from the vertical direction Z. By bending and extending the second fixing element 54 along the outer circumferential surface of the cylindrical element 31a rearward from the top 31d, it is possible to attach the second fixing element 54 appropriately to the cylindrical element 31a without providing a separate leg between the first main body 51 and the second fixing element 54. As such, it is possible to simplify the shape of the first mounting part 50 and to attach the first mounting part 50 appropriately to the receptacle 30.Apart from the boundary area 58 with the second fixing element 54, it is possible to arrange the first main body 51 separately from the cylindrical element 31a. Accordingly, even in a case where the first main body 51 vibrates, it is possible to prevent the first main body 51 from colliding with the cylindrical element 31a, and it is possible to suppress the generation of noise.

[0085] According to the first embodiment, the first elastic part 71 projects further rearward (-X-side) in the front-back direction X than the second support part 60. As such, a portion of the supported line 19a that projects further rearward than the second support part 60 is prevented from directly colliding with the first support part 50 by means of the first elastic part 71. Accordingly, it is possible to prevent the supported line 19a from directly colliding with the first support part 50 and generating noise.

[0086] According to the first embodiment, the first support part 50 comprises the lower wall 55, which is located in the vertical direction Z below the supported conduit 19a. The support 40 comprises the third elastic part 73, at least a portion of which is located in the vertical direction Z between the lower wall 55 and the supported conduit 19a. This makes it possible to support the supported conduit 19a from below using the lower wall 55 and the third elastic part 73. Accordingly, when attaching the second support part 60 to the first support part 50, it is possible to support the supported conduit 19a from below through the first support part 50 using the lower wall 55. Therefore, it is possible to perform work to attach the second support part 60 to the first support part 50 and to easily enclose the supported conduit 19a between them.Using the lower wall 55, it is also possible to prevent the supported conduit 19a from emerging between the first main body 51 and the second main body 61 at the bottom. Since the third elastic part 73 is provided, it is possible to prevent the supported conduit 19a from colliding directly with the lower wall 55 and to prevent noise from occurring.

[0087] According to the first embodiment, the second support part 60 comprises the upper wall 62, which is located in the vertical direction Z above the supported conduit 19a. The support 40 comprises the fourth elastic part 74, at least a portion of which is located in the vertical direction Z between the upper wall 62 and the supported conduit 19a. Thus, in a case where the supported conduit 19a is located in the Fig. As the position shown in Figure 7 is moved upwards, etc., it is possible to hold the supported conduit 19a from above using the upper wall 62 over the fourth elastic part 74. Accordingly, it is possible to prevent the supported conduit 19a from emerging between the first main body 51 and the second main body 61 at the top. Since the fourth elastic part 74 is provided, it is possible to prevent the supported conduit 19a from colliding directly with the upper wall 62 and to prevent noise from being generated.

[0088] According to the first embodiment, the second mounting part 60 comprises the first fastening part 63, which is attached to the first main body 51 using the first screw element 81, and the second fastening part 65, which is located further down than the first fastening part 63 and is attached to the projection 56 using the second screw element 82. The second fastening part 65 is located further to the right (+Y-side) than the first fastening part 63. The first screw element 81 is located further forward (+X-side) in the front-back direction X than the second screw element 82. Thus, it is possible to position the first screw hole 57a, in which the first screw element 81 is fastened, at a distance from where the top 31d is located. Accordingly, it is possible to provide the first screw hole 57a within a relatively large distance in the left-right direction Y between the first main body 51 and the cylindrical element 31a.Therefore, even if the first fastening part 63 is attached to the first main body 51 using the first screw element 81, it is possible to prevent the first screw element 81 from colliding with the cylindrical element 31a. On the other hand, by positioning the second fastening part 65 further to the right than the first fastening part 63, it is possible to position the portion of the first mounting part 50 to which the second fastening part 65 is attached—in other words, the projection 56—further away from the cylindrical element 31a in the left-right direction Y than from the first main body 51. Accordingly, even if the projection 56 is attached to the center of the second fastening part 65 in the front-back direction X using the second screw element 82, it is possible to prevent the second screw element 82 from colliding with the cylindrical element 31a.

[0089] According to the first embodiment, the second mounting part 60 comprises the bend 64, which curves to the left (-Y side) from a lower end of the second main body 61 in the left-right direction Y. The second fastening part 65 projects downwards from a left end of the bend 64. Thus, it is possible to position the second fastening part 65 further to the left than the second main body 61. Accordingly, it is possible to position the screw head of the second screw element 82, which fastens the second fastening part 65, below the bend 64, as shown in Fig. Figure 7 shows that it is possible to prevent the screw head of the second screw element 82 from projecting further to the right (+Y-side) than the second main body 61. Thus, it is possible to prevent the screw head of the second screw element 82 from touching the opposite wall 11d.

[0090] According to the first embodiment, the bracket 40 comprises the fifth elastic part 75, which is attached to a right (+Y-side) surface of the second main body 61. The fifth elastic part 75 is located in the left-right direction Y between the second main body 61 and the opposite wall 11d. Thus, even if the bracket 40 vibrates, etc., the fifth elastic part 75 prevents the second bracket part 60 from directly contacting the opposite wall 11d. Accordingly, noise generation is suppressed. Since it is possible to dampen vibrations using the fifth elastic part 75, it is possible to prevent vibrations from being transmitted to the opposite wall 11d, even if the second bracket part 60 is in contact with the opposite wall 11d.

[0091] According to the first embodiment, the second mounting part 60 comprises the hook 66, which is hooked onto the first mounting part 50 from above in the vertical direction Z. By hooking the hook 66 onto the first mounting part 50 from above, the second mounting part 60 can be held relative to the first mounting part 50 when it is being attached to the first mounting part 50, which is attached to the receptacle 30. Accordingly, it is not necessary to hold the second mounting part 60 with one hand when attaching it to the first mounting part 50, and the work can be carried out easily.In the first embodiment, it is possible to carry out fastening operations of the second mounting part 60 to the first mounting part 50 using the first screw element 81 and the second screw element 82 in a state in which the hook 66 is hooked from above onto the first main body 51 and the second mounting part 60 is held by the first mounting part 50.

[0092] According to the first embodiment, the downwardly recessed recess 51a is formed at an upper end of the first mounting part 50 in the vertical direction Z. The hook 66 is engaged from above in the recess 51a. By engaging the hook 66 in the portion of the first mounting part 50 where the recess 51a is formed, it is possible to hold the second mounting part 60 in a position relative to the first mounting part 50 to a certain extent. To prevent the hook 66 from moving in the front-back direction X along both edges of the recess 51a in the front-back direction X, it is possible to prevent the second mounting part 60 from being displaced relative to the first mounting part 50 when fastening operations are performed on the second mounting part 60 to the first mounting part 50. Second embodiment

[0093] Fig. Figure 13 is a perspective view showing part of an outdoor unit 210 in a second embodiment. In the following explanations, identical configurations have the same reference numerals or the like assigned to them, without their explanations.

[0094] As in Fig. As shown in Figure 13, in the second embodiment, the bracket 40 holds two of the held conduits 19a. The two held conduits 19a are arranged in the vertical direction Z with a space between them. Thus, in a case where the two held conduits 19a are held by the bracket 40, it is easy to use the lower wall 55 via the third elastic part 73 to hold the lower held conduit 19a from below, and it is easy to use the upper wall 62 via the fourth elastic part 74 to hold the upper held conduit 19a from above. Therefore, it is easy to suitably hold the two held conduits 19a in the vertical direction Z. Other configurations of the outdoor unit 210 are the same as the other configurations of the outdoor unit 10 of the first embodiment. Third embodiment

The three held conduits 19a are arranged such that they are aligned in the vertical direction Z with a distance between them. Thus, when the three held conduits 19a are held by the bracket 340, it is easy to hold the bottommost held conduit 19a from below using the lower wall 55 over the third elastic part 73, and it is easy to hold the topmost held conduit 19a from above using the upper wall 62 over the fourth elastic part 74. Compared to the bracket 40 in the first embodiment, one dimension of the bracket 340 in the vertical direction Z is large.
