Description

Refrigeration cycle equipment

[0001] The present disclosure relates to a refrigeration cycle device.

[0002] A refrigeration cycle apparatus such as an air conditioner includes a heat exchanger and a housing that houses the heat exchanger. Patent Document 1 discloses, as an example of a refrigeration cycle apparatus, an air conditioner that includes a housing and a heat exchanger housed in the housing. In a conventional refrigeration cycle apparatus, the heat exchanger is fixed to the housing as follows: The conventional refrigeration cycle apparatus includes a fixing plate fixed to the housing. A female screw is formed in the fixing plate. The conventional refrigeration cycle apparatus also includes a mounting plate provided at an end of the heat exchanger. A through hole is formed in the mounting plate. In the conventional refrigeration cycle apparatus, a male screw inserted into the through hole in the mounting plate is screwed into the female screw in the mounting plate, thereby fixing the heat exchanger to the housing.

[0003] Japanese Patent Application Laid-Open No. 2020-20574

[0004] In some cases, a heat exchanger is bent at least at one location to form a generally L-shaped or U-shaped configuration and then housed in a housing. In such cases, processing errors during the bending process can cause misalignment of the through-holes in the mounting plate relative to the female threads of the fixing plate. This makes it difficult for conventional refrigeration cycle devices to thread the male screws inserted into the through-holes in the mounting plate into the female threads of the fixing plate, making it difficult to secure the heat exchanger to the housing.

[0005] The present disclosure is made to solve the above-mentioned problems, and has an object to provide a refrigeration cycle device in which the work of fixing a heat exchanger to a housing is easier than before.

[0006] A refrigeration cycle apparatus according to the present disclosure includes a housing, a heat exchanger accommodated in the housing, a first fixing plate fixed to the housing, a second fixing plate fixed to the first fixing plate, a mounting plate provided on the heat exchanger and fixed to the second fixing plate, a first male screw that fixes the first fixing plate to the second fixing plate, and a second male screw that fixes the second fixing plate to the mounting plate, wherein one of the first fixing plate and the second fixing plate is formed with a first elongated hole that extends in a direction in which a contact portion of the second fixing plate with the mounting plate and a contact portion of the mounting plate with the second fixing plate face each other, and The other of the two fixing plates has a first female screw formed in a position facing the first long hole, one of the second fixing plate and the mounting plate has a second long hole formed in the penetrating direction of the first long hole, and the other of the second fixing plate and the mounting plate has a second female screw formed in a position facing the second long hole, and the first fixing plate and the second fixing plate are fixed together by the first male screw inserted into the first long hole being screwed into the first female screw, and the second fixing plate and the mounting plate are fixed together by the second male screw inserted into the second long hole being screwed into the second female screw.

[0007] In the refrigeration cycle apparatus according to the present disclosure, processing errors in bending the heat exchanger can be absorbed in two directions, that is, the longitudinal direction of the first oblong hole and the longitudinal direction of the second oblong hole, making it easier than ever to fix the heat exchanger to the housing.

[0009] In the following embodiments, an example of a refrigeration cycle device according to the present disclosure will be described. Note that in the following embodiments, the example of the refrigeration cycle device according to the present disclosure will be described while observing the example of the refrigeration cycle device according to the present disclosure in an installed state. Furthermore, in the following embodiments, for convenience of explanation, the surface of the housing on which the air outlet is formed will be described as the front surface of the housing.

[0010] Embodiment 1. Fig. 1 is a view of the interior of the outdoor unit of a refrigeration cycle apparatus according to Embodiment 1, observed from above. Fig. 2 is a view of the interior of the outdoor unit of a refrigeration cycle apparatus according to Embodiment 1, observed from the front. Fig. 3 is a perspective view showing a heat exchanger of the outdoor unit of the refrigeration cycle apparatus according to Embodiment 1. In other words, Fig. 1 is a view of the outdoor unit 1 of a refrigeration cycle apparatus 100, from which a top surface 15 (described later) of a housing 10 has been removed, observed from above. Fig. 2 is a view of the outdoor unit 1 of a refrigeration cycle apparatus 100, from which a front surface 11 (described later) of a housing 10 has been removed, observed from the front.

[0011] The refrigeration cycle apparatus 100 is an apparatus equipped with a refrigeration cycle circuit, such as an air conditioner, a refrigeration apparatus, a water heater, etc. The refrigeration cycle apparatus 100 includes an outdoor unit 1. The outdoor unit 1 includes a housing 10 and a heat exchanger 20.

[0012] The housing 10 according to the first embodiment has a substantially rectangular parallelepiped shape and includes a front surface 11, a rear surface 12, a left side surface 13, a right side surface 14, a top surface 15, and a base plate 16. The base plate 16 forms the bottom surface of the housing 10. Air inlets 10a are formed in the left side surface 13 and the rear surface 12. An air outlet 10b is formed in the front surface 11. The housing 10 also includes a partition plate 17 that separates the interior of the housing 10 into a blower chamber 18 and a machine chamber 19.

[0013] The heat exchanger 20 is housed in the housing 10. Specifically, the heat exchanger 20 is housed in the fan chamber 18 of the housing 10 so as to face the air inlet 10a. As described above, the air inlet 10a is formed in the left side surface portion 13 and the rear surface portion 12. Therefore, in the first embodiment, the heat exchanger 20 is bent at one location to form a substantially L-shape. The fan chamber 18 also houses the fan 2. Therefore, when the fan 2 is driven, air outside the housing 10 is drawn into the housing 10 through the air inlet 10a. The air drawn into the housing 10 passes through the heat exchanger 20 and is then blown out of the housing 10 through the air outlet 10b. The machine chamber 19 also houses the compressor 3 and other components.

[0014] The heat exchanger 20 includes a heat exchange section 21, a header 22, a gas pipe 23, and a liquid pipe 24. The heat exchange section 21 is a location where heat exchange occurs between the refrigerant flowing through the heat exchanger 20 and a heat exchange target such as air. In the first embodiment, the heat exchange section 21 includes a plurality of flat tubes and a plurality of fins connected to the flat tubes. Each of the flat tubes has a plurality of refrigerant flow paths. That is, the heat exchanger 20 according to the first embodiment is a parallel-flow heat exchanger. The header 22 distributes the refrigerant flowing into the header 22 to the flat tubes of the heat exchange section 21. The header 22 is a location where the refrigerant flowing out of the flat tubes of the heat exchange section 21 converge. The gas pipe 23 is a pipe through which the gas refrigerant flowing into the heat exchanger 20 and the gas refrigerant flowing out of the heat exchanger 20 flows. The liquid pipe 24 is a pipe through which the gas-liquid two-phase refrigerant flowing into the heat exchanger 20 and the liquid refrigerant flowing out from the heat exchanger 20 flow.

[0015] The above-described configuration of the heat exchanger 20 is merely an example. For example, the heat exchange section 21 of the heat exchanger 20 may include a plurality of circular pipes through which the refrigerant flows. Furthermore, for example, the heat exchanger 20 may have a shape different from the above-described shape.

[0016] Fig. 4 is a perspective view showing another example of the heat exchanger of the refrigeration cycle apparatus according to Embodiment 1. The heat exchanger 20 may have a shape that is bent at multiple locations. Fig. 4 shows an example of the heat exchanger 20 that is bent at two locations and formed into a substantially U-shape. When the outdoor unit 1 is equipped with the heat exchanger 20 shown in Fig. 4, the suction ports 10a are formed on three side surfaces of the housing 10.

[0017] The refrigeration cycle apparatus 100 includes a mounting plate 50 provided on the heat exchanger 20. The mounting plate 50 is fixed to, for example, the header 22. The heat exchanger 20 is fixed to the housing 10 using the mounting plate 50.

[0018] In conventional refrigeration cycle devices, the heat exchanger is fixed to the housing using a mounting plate provided on the heat exchanger. However, the position of the mounting plate may deviate from the desired position due to processing errors during bending. Taking the heat exchanger 20 according to the first embodiment as an example, the bent heat exchanger 20 has processing errors in dimensions A shown in FIG. 3 , B shown in FIG. 3 , C shown in FIG. 4 , D shown in FIG. 4 , and E shown in FIG. 4 . As a result, the mounting plate 50 may deviate from the desired position in the front-rear and left-right directions.

[0019] Due to the above-described processing error in the bending process, in the conventional refrigeration cycle apparatus, the work of fixing the heat exchanger to the housing may be difficult as described below.

[0020] 5 is a perspective view showing the periphery of a fixing structure between a heat exchanger and a housing in a conventional refrigeration cycle apparatus. The conventional refrigeration cycle apparatus includes a fixing plate 230 fixed to the housing. The fixing plate 230 has a female screw 231 formed therein. The conventional refrigeration cycle apparatus also includes a mounting plate 250 provided at an end of the heat exchanger 220. The mounting plate 250 has a through hole 251 formed therein. In the conventional refrigeration cycle apparatus, a male screw inserted into the through hole 251 in the mounting plate 250 is screwed into the female screw 231 in the mounting plate 230, thereby fixing the heat exchanger to the housing. In this case, due to processing errors in the bending process as described above, the position of the through hole 251 in the mounting plate 250 may be misaligned in the front-to-rear and left-to-right directions with respect to the female screw 231 in the mounting plate 230. For this reason, in conventional refrigeration cycle devices, it is difficult to screw the male screw inserted into the through hole 251 of the mounting plate 250 into the female screw 231 of the fixing plate 230, making it difficult to fix the heat exchanger 220 to the housing.

[0021] Therefore, in the refrigeration cycle apparatus 100 according to the first embodiment, the heat exchanger 20 is fixed to the housing 10 as follows.

[0022] Figures 6 and 7 are perspective views of the periphery of a fixing structure between a heat exchanger and a housing in the refrigeration cycle apparatus according to Embodiment 1, observed from the front. Note that Figure 6 shows the fixing structure that fixes the upper part of the heat exchanger 20 to the housing 10. Also, Figure 7 shows the fixing structure that fixes the lower part of the heat exchanger 20 to the housing 10. Also, the header 22 of the heat exchanger 20 shown in Figures 6 and 7 is the header 22 shown on the left side of the paper in Figure 4.

[0023] The refrigeration cycle apparatus 100 includes a first fixing plate 30, a second fixing plate 40, a first male screw 61, and a second male screw 62. As described above, the refrigeration cycle apparatus 100 also includes an attachment plate 50 provided on the heat exchanger 20. The first fixing plate 30 is fixed to the housing 10 by welding, screwing, or the like. In the first embodiment, the first fixing plate 30 is fixed to the left side surface 13 of the housing 10. The second fixing plate 40 is fixed to the first fixing plate 30. The attachment plate 50 is fixed to the second fixing plate 40. The first male screw 61 is a male screw that fixes the first fixing plate 30 and the second fixing plate 40 together. The second male screw 62 is a male screw that fixes the second fixing plate 40 and the attachment plate 50 together. Here, in the refrigeration cycle apparatus 100 according to the first embodiment, the first fixing plate 30 and the second fixing plate 40 are fixed as follows. In the refrigeration cycle apparatus 100 according to the first embodiment, the second fixing plate 40 and the mounting plate 50 are fixed to each other as follows.

[0024] A first oblong hole 41 is formed in the second fixing plate 40. The first oblong hole 41 extends in a direction in which a contact point of the second fixing plate 40 with the mounting plate 50 and a contact point of the mounting plate 50 with the second fixing plate 40 face each other. In the first embodiment, the first oblong hole 41 extends in the left-right direction. Meanwhile, a first female screw 31 is formed in the first fixing plate 30 at a position facing the first oblong hole 41. The first fixing plate 30 and the second fixing plate 40 are fixed together by a first male screw 61 inserted into the first oblong hole 41 and threaded into the first female screw 31. The first oblong hole 41 may be formed in the first fixing plate 30. In this case, the first female screw 31 is formed in the second fixing plate 40. That is, the first oblong hole 41 is formed in one of the first fixing plate 30 and the second fixing plate 40. Furthermore, a first female screw 31 is formed on the other of the first fixing plate 30 and the second fixing plate 40 .

[0025] The mounting plate 50 has a second oblong hole 51 formed therein, extending in the penetration direction of the first oblong hole 41. In the first embodiment, the second oblong hole 51 extends in the front-rear direction. Meanwhile, the second mounting plate 40 has a second female screw 42 formed therein at a position facing the second oblong hole 51. The second mounting plate 40 and the mounting plate 50 are fixed together by a second male screw 62 inserted into the second oblong hole 51 and threaded into the second female screw 42. The second oblong hole 51 may also be formed in the second mounting plate 40. In this case, the second female screw 42 is formed in the mounting plate 50. That is, the second oblong hole 51 is formed in one of the second mounting plate 40 and the mounting plate 50. The second female screw 42 is formed in the other of the second mounting plate 40 and the mounting plate 50.

[0026] By fixing the first fixing plate 30 and the second fixing plate 40 and fixing the second fixing plate 40 and the mounting plate 50 in this manner, the heat exchanger 20 is fixed to the housing 10. At this time, in the refrigeration cycle apparatus 100 according to the first embodiment, processing errors in the bending of the heat exchanger 20 can be absorbed in two directions, that is, in the longitudinal direction of the first oblong holes 41 and the longitudinal direction of the second oblong holes 51. Specifically, in the first embodiment, the first oblong holes 41 can absorb left-right deviations of the mounting plate 50 due to processing errors in the bending of the heat exchanger 20. Furthermore, the second oblong holes 51 can absorb front-rear deviations of the mounting plate 50 due to processing errors in the bending of the heat exchanger 20. Therefore, in the refrigeration cycle apparatus 100 according to the first embodiment, the task of fixing the heat exchanger 20 to the housing 10 is easier than in the conventional case.

[0027] Furthermore, in the refrigeration cycle apparatus 100 according to the first embodiment, the second fixing plate 40 is formed with a through-hole 32 that penetrates in the longitudinal direction of the second oblong hole 51 and into which the mounting plate 50 is inserted. Therefore, the refrigeration cycle apparatus 100 according to the first embodiment can suppress interference between the mounting plate 50 and the second fixing plate 40. Therefore, the refrigeration cycle apparatus 100 according to the first embodiment can better absorb processing errors in the longitudinal direction of the second oblong hole 51 that occur during bending of the heat exchanger 20. Therefore, the refrigeration cycle apparatus 100 according to the first embodiment makes it easier to fix the heat exchanger 20 to the housing 10.

[0028] Furthermore, in the refrigeration cycle apparatus 100 according to the first embodiment, the contact points of the first fixing plate 30 with the second fixing plate 40 and the contact points of the second fixing plate 40 with the first fixing plate 30 are surfaces that extend in the vertical direction. For example, the contact points of the first fixing plate 30 with the second fixing plate 40 and the contact points of the second fixing plate 40 with the first fixing plate 30 are flat. Note that the contact points of the first fixing plate 30 with the second fixing plate 40 and the contact points of the second fixing plate 40 with the first fixing plate 30 may be surfaces other than flat surfaces as long as they extend in the vertical direction. Furthermore, the vertical direction in the first embodiment does not necessarily refer to a direction that is strictly parallel to the vertical direction, but may also be inclined with respect to the vertical direction.

[0029] The first fixing plate 30 and the second fixing plate 40 may be formed from different metals. In such a case, if water accumulates at the contact points between the first fixing plate 30 and the second fixing plate 40, galvanic corrosion may occur. However, by configuring the contact points between the first fixing plate 30 and the second fixing plate 40 and the contact points between the second fixing plate 40 and the first fixing plate 30 as described above, it is possible to prevent water from accumulating at the contact points between the first fixing plate 30 and the second fixing plate 40. As a result, it is possible to prevent galvanic corrosion from occurring.

[0030] Furthermore, in the refrigeration cycle apparatus 100 according to the first embodiment, the contact points of the second fixing plate 40 with the mounting plate 50 and the contact points of the mounting plate 50 with the second fixing plate 40 are surfaces that extend in the vertical direction. For example, the contact points of the second fixing plate 40 with the mounting plate 50 and the contact points of the mounting plate 50 with the second fixing plate 40 are flat. Note that the contact points of the second fixing plate 40 with the mounting plate 50 and the contact points of the mounting plate 50 with the second fixing plate 40 may be surfaces other than flat surfaces as long as they extend in the vertical direction.

[0031] It is also conceivable that the second fixing plate 40 and the mounting plate 50 are formed of different metals. In such a case, if water accumulates at the contact points between the second fixing plate 40 and the mounting plate 50, galvanic corrosion may occur. However, by configuring the contact points of the second fixing plate 40 with the mounting plate 50 and the contact points of the mounting plate 50 with the second fixing plate 40 as described above, it is possible to prevent water from accumulating at the contact points between the second fixing plate 40 and the mounting plate 50. As a result, it is possible to prevent galvanic corrosion from occurring.

[0032] Furthermore, the refrigeration cycle apparatus 100 according to the first embodiment is configured such that the second male screw 62 is threaded into the second female screw 42 in a direction from the outside of the housing 10 toward the inside of the housing 10. Because structures such as piping are arranged inside the housing 10, it may be difficult to connect a tool for turning the second male screw 62 to the second male screw 62. However, by configuring the second male screw 62 to be threaded into the second female screw 42 in a direction from the outside of the housing 10 toward the inside of the housing 10, it becomes easier to connect a tool to the second male screw 62, and the task of fixing the heat exchanger 20 to the housing 10 becomes easier.

[0033] 8 is a perspective view of the periphery of a fixing structure between a heat exchanger and a housing in another example of the refrigeration cycle apparatus according to the first embodiment, as viewed from the front. When the second male screw 62 is configured to be threaded into the second female screw 42 in a direction from the outside of the housing 10 toward the inside of the housing 10, depending on the shape of the first fixing plate 30, the first fixing plate 30 may be positioned opposite the head of the second male screw 62, making it difficult to thread the second male screw 62 into the second female screw 42. In such a case, as shown in FIG. 8 , a through hole 33 may be formed in the first fixing plate 30 at a position opposite the head of the second male screw 62. This allows the second male screw 62 to be threaded into the second female screw 42 in a direction from the outside of the housing 10 toward the inside of the housing 10. The same applies to the case where the second fixing plate 40 is positioned opposite the head of the second male screw 62.

[0034] As described above, the refrigeration cycle apparatus 100 according to the first embodiment includes the housing 10, the heat exchanger 20 housed in the housing 10, the first fixing plate 30 fixed to the housing 10, the second fixing plate 40 fixed to the first fixing plate 30, the mounting plate 50 provided on the heat exchanger 20 and fixed to the second fixing plate 40, a first male screw 61 that fixes the first fixing plate 30 to the second fixing plate 40, and a second male screw 62 that fixes the second fixing plate 40 to the mounting plate 50. One of the first fixing plate 30 and the second fixing plate 40 has a first elongated hole 41 formed therein, the first elongated hole 41 extending in a direction in which a contact point of the second fixing plate 40 with the mounting plate 50 and a contact point of the mounting plate 50 with the second fixing plate 40 face each other. The other of the first fixing plate 30 and the second fixing plate 40 has a first female screw 31 formed therein at a position facing the first elongated hole 41. One of the second fixing plate 40 and the mounting plate 50 has a second oblong hole 51 formed therein, extending in the penetration direction of the first oblong hole 41. The other of the second fixing plate 40 and the mounting plate 50 has a second female screw 42 formed therein at a position facing the second oblong hole 51. The first fixing plate 30 and the second fixing plate 40 are fixed together by a first male screw 61 inserted into the first oblong hole 41 and screwed into the first female screw 31. The second fixing plate 40 and the mounting plate 50 are also fixed together by a second male screw 62 inserted into the second oblong hole 51 and screwed into the second female screw 42.

[0035] In the refrigeration cycle apparatus 100 configured in this manner, as described above, processing errors in the bending of the heat exchanger 20 can be absorbed in two directions, that is, the longitudinal direction of the first oblong hole 41 and the longitudinal direction of the second oblong hole 51. Therefore, as described above, the refrigeration cycle apparatus 100 configured in this manner makes the work of fixing the heat exchanger 20 to the housing 10 easier than in the conventional case.

[0036] In the first embodiment, the fixing structure between the housing and the heat exchanger using the first fixing plate 30, the second fixing plate 40, the mounting plate 50, the first male screw 61, and the second male screw 62 is used to fix the heat exchanger 20 to the housing 10 of the outdoor unit 1. However, the fixing structure between the housing and the heat exchanger using the first fixing plate 30, the second fixing plate 40, the mounting plate 50, the first male screw 61, and the second male screw 62 may be employed in a refrigeration cycle apparatus 100 unit other than the outdoor unit 1. An example of a refrigeration cycle apparatus 100 unit other than the outdoor unit 1 is an indoor unit when the refrigeration cycle apparatus 100 is an air conditioning apparatus.

[0037] Embodiment 2 By adding a closing plate shown in Embodiment 2 to the refrigeration cycle apparatus 100 shown in Embodiment 1, the performance of the refrigeration cycle apparatus 100 is improved. Note that matters not specifically mentioned in Embodiment 2 are the same as in Embodiment 1. Also, in Embodiment 2, components that perform the same functions as the components shown in Embodiment 1 are assigned the same reference numerals as in Embodiment 1.

[0038] FIG. 9 is a perspective view of the periphery of a fixing structure between a heat exchanger and a housing in a refrigeration cycle apparatus according to the second embodiment, observed from the front. FIG. 9 shows a fixing structure that fixes the upper part of the heat exchanger 20 to the housing 10. The dashed arrows in FIG. 9 indicate the flow of air that has flowed into the housing 10. The refrigeration cycle apparatus 100 according to the second embodiment includes a closing plate 70 that closes the gap between the second fixing plate 40 and the heat exchanger 20. The refrigeration cycle apparatus 100 according to the second embodiment also includes a closing plate 71 that closes the gap between the first fixing plate 30 and the second fixing plate 40. The closing plate 70 may be manufactured by any method. For example, the closing plate 70 may be formed integrally with the first fixing plate 30. Alternatively, the closing plate 70 may be formed integrally with the second fixing plate 40. Alternatively, the closing plate 70 may be formed separately from the first fixing plate 30 and the second fixing plate 40. The closing plate 71 may also be manufactured by any method. For example, the closing plate 71 may be formed integrally with the first fixed plate 30. Also, for example, the closing plate 71 may be formed integrally with the second fixed plate 40. Also, for example, the closing plate 71 may be formed separately from the first fixed plate 30 and the second fixed plate 40.

[0039] When air flows into the housing 10 through an opening such as the air inlet 10a, the performance of the refrigeration cycle apparatus 100 is improved if as much air as possible passes through the heat exchanger 20. Here, in the refrigeration cycle apparatus 100 according to the second embodiment, the closing plate 70 can prevent the air that has flowed into the housing 10 from passing between the second fixing plate 40 and the heat exchanger 20. Furthermore, in the refrigeration cycle apparatus 100 according to the second embodiment, the closing plate 71 can prevent the air that has flowed into the housing 10 from passing between the first fixing plate 30 and the second fixing plate 40. Therefore, the refrigeration cycle apparatus 100 according to the second embodiment can reduce the amount of air that passes through the housing 10 without passing through the heat exchanger 20. Therefore, in addition to the effects shown in the first embodiment, the refrigeration cycle apparatus 100 according to the second embodiment also achieves the effect of improving the performance of the refrigeration cycle apparatus 100.
