Description

Technical Field

[0001] It relates to a compressor and a refrigeration cycle apparatus including the same.

Background Art

[0002] Conventionally, there has been a compressor including a first container having a compression section therein and a second container for storing refrigerant before it enters the first container. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2015-68323) discloses a rotary compressor in which pipes for sending refrigerant to each of two compression sections extend upward from the lower part of the second container.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In a compressor as described above, the pipes extending vertically in the internal space of the second container may vibrate. In particular, when a plurality of pipes are arranged in the second container, the amplitude and vibration noise may increase due to resonance. To avoid resonance, it is conceivable to lower the upper end position of one of the pipes, but in such a case, there is a demerit that the refrigerant storage amount in the second container decreases.

Means for Solving the Problems

[0004] The compressor according to the first aspect includes a first container, a second container, a first pipe, and a second pipe. The first container has a first compression section and a second compression section. The second container stores refrigerant before it enters the first container. The first pipe allows the refrigerant flowing from the upper space of the second container to the first compression section to pass therethrough. The second pipe allows the refrigerant flowing from the upper space of the second container to the second compression section to pass therethrough. The first pipe and the second pipe extend upward from the lower part of the second container to the upper space of the second container. The upper end of the first pipe and the upper end of the second pipe are at substantially the same height position. In the second container, a first position is higher than a second position. The first position is the height position of the upper end of the first fixing portion. The first fixing portion is a portion of the second container where the first pipe is fixed. The second position is the height position of the upper end of the second fixing portion. The second fixing portion is a portion of the second container where the second pipe is fixed.

[0005] In this compressor, the upper ends of the first and second pipes, which extend upward from the lower part of the second container to the upper space of the second container, are aligned at the same height to ensure the amount of refrigerant that can be stored in the second container. Furthermore, in this compressor, the height of the upper end of the first fixing part to which the first pipe is fixed (first position) is set higher than the height of the upper end of the second fixing part to which the second pipe is fixed (second position). This shifts the natural frequencies of the first pipe and the second pipe, thereby avoiding resonance between the first and second pipes and suppressing vibration of the compressor. Therefore, according to the compressor in the first view, it is possible to suppress vibration of the first and second pipes while ensuring the amount of refrigerant that can be stored in the second container.

[0006] The compressor in the second perspective is the compressor in the first perspective, and the difference is 9% or more of the second distance. The second distance is the distance from the top of the second fixed part to the top of the second pipe. The difference is the value obtained by subtracting the first distance from the second distance. The first distance is the distance from the top of the first fixed part to the top of the first pipe.

[0007] Here, the second distance, which is the length of the second pipe extending from the second fixed part, is 9% or more greater than the first distance, which is the length of the first pipe extending from the first fixed part, making it possible to more reliably shift the natural frequencies of the first pipe and the second pipe.

[0008] The compressor in the third perspective is the compressor in the second perspective, and the difference is 55% or less of the second distance.

[0009] Here, the ratio of the second distance, which is the length of the second pipe extending from the second fixed part, to the first distance, which is the length of the first pipe extending from the first fixed part, is kept within a predetermined range. This suppresses the problem of the first natural frequency of the first pipe and the second and higher natural frequencies of the second pipe becoming too close together.

[0010] A compressor according to the fourth aspect is a compressor according to the first or second aspect, further comprising a fixing member fixed to the second container. The first fixing part is formed on the fixing member. The second fixing part is formed on the bottom of the second container.

[0011] Here, a configuration is adopted in which a fixing member is prepared and fixed to the second container. This eliminates the need to mold the casing of the second container into a complex shape, and also makes it easy to separate the first and second positions.

[0012] The compressor in the fifth perspective is the compressor in the fourth perspective, wherein a first through-hole is formed in the fixing member. The first through-hole is located above the bottom of the second container, and the first pipe passes through it. The first pipe is fixed to the fixing member while passing through the first through-hole.

[0013] In this configuration, the first pipe, which has passed through the first through-hole, is fixed to the fixing member. This allows the fixing member to be positioned high up, far from the bottom of the second container.

[0014] The compressor in the sixth view is the compressor in the fifth view, and the fixing member further has a second through-hole formed therein. The second through-hole is located above the bottom of the second container, and the second pipe passes through it. The second pipe has a gap between it and the fixing member as it passes through the second through-hole.

[0015] Here, since a second through-hole is made in the fixing member, the second pipe can be extended upward from the bottom of the second container without having to avoid the fixing member.

[0016] The refrigeration cycle device of the seventh aspect comprises a compressor of any of the first to sixth aspects. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0018] (1) Configuration of the Refrigeration Cycle Device The configuration of the refrigeration cycle device 1 including the compressor 6 is shown in FIG. 1. FIG. 1 is also a refrigerant circuit diagram of the refrigeration cycle device 1. The refrigeration cycle device 1 of the present embodiment is, as its application, an air conditioner for performing air conditioning in a building, a water heater, a device for generating cold and warm water, etc., and modifications of the configuration suitable for each application are made. Here, the refrigeration cycle device 1 as an air conditioner for performing air conditioning will be described.

[0019] The refrigeration cycle device 1 includes a heat source unit 2 and a utilization unit 3. The heat source unit 2 includes a compressor 6, a four-way switching valve 8, a heat source side heat exchanger 4, and an expansion valve 7. The utilization unit 3 includes a utilization side heat exchanger 5. In the utilization side heat exchanger 5, the refrigerant exchanges heat with the air in the building. When the refrigerant exchanges heat with another medium such as water in the utilization side heat exchanger, the utilization side heat exchanger may be arranged outside the building.

[0020] The refrigerant circuit of the refrigeration cycle device 1 mainly has a compressor 6, a four-way switching valve 8, a heat source side heat exchanger 4, an expansion valve 7, and a utilization side heat exchanger 5, and each device is connected by refrigerant pipes.

[0021] The compressor 6 compresses the refrigerant. The four-way switching valve 8 switches the flow of the refrigerant between the broken line (heating) and the solid line (cooling) in FIG. 1.

[0022] During the heating operation, the refrigerant discharged from the compressor 6 is sucked into the compressor 6 again via the utilization side heat exchanger 5, the expansion valve 7, and the heat source side heat exchanger 4. In other words, during heating, the utilization side heat exchanger 5 functions as a radiator, and the heat source side heat exchanger 4 functions as an evaporator.

[0023] During the cooling operation, the refrigerant discharged from the compressor 6 passes through the heat source side heat exchanger 4, the expansion valve 7, and the utilization side heat exchanger 5, and is inhaled into the compressor 6 again. In other words, during cooling, the heat source side heat exchanger 4 functions as a radiator, and the utilization side heat exchanger 5 functions as an evaporator.

[0024] (2) Structure of the compressor The longitudinal sectional view of the compressor 6 is shown in FIG. 2. The compressor 6 mainly includes a first container 10 that is a main body having a compression function, a second container 20 that stores the refrigerant before it enters the first container 10, and a first pipe 50 and a second pipe 60 that guide the refrigerant from the second container 20 to the first container 10.

[0025] (2-1) The first container The first container 10 is a compressor in the narrow sense. It compresses the refrigerant inhaled from the second container 20 and discharges the refrigerant toward the four-way switching valve 8 through the discharge pipe 18. Inside the first container 10, there are a first compression part 11, a second compression part 12, a crankshaft 十六, a motor 17, etc. The first container 10 is a so-called two-cylinder type rotary compressor that compresses the refrigerant in two cylinders. Here, the lower cylinder is referred to as the first compression part 11, and the upper cylinder is referred to as the second compression part 12. The first compression part 11 and the second compression part 12 each have a cylinder chamber and a piston, and the crankshaft 16 rotates the piston to compress the refrigerant. The crankshaft 16 is rotated by the motor 17.

[0026] (2-2) The second container The second container 20 is a refrigerant reservoir also called an accumulator. The second container 20 has an upper casing 21 and a lower casing 22. The upper surface of the upper casing 21 is the upper surface 21a of the second container 20. The bottom surface of the lower casing 22 is the bottom surface 22a of the second container 20. The lower part of the cylindrical part of the upper casing 21 and the upper part of the cylindrical part of the lower casing 22 are welded together all around.

[0027] The second container 20 is fixed to the first container 10 by a support member 80 shown in Figure 2. The support member 80 has, for example, a support base and fastening band as described in Japanese Patent Application Publication No. 2021-88947, and supports the second container 20 to the first container 10 via a cushioning member made of a material such as rubber.

[0028] Refrigerant flows into the internal space of the second container 20 from an inlet pipe 40 that penetrates the upper surface 21a of the second container 20. Below the inlet pipe 40, a baffle plate 28, as shown in Figure 3, is positioned, and if the incoming refrigerant is a gas-liquid two-phase system, the refrigerant is separated into a gaseous component and a liquid component. Below the baffle plate 28, the vertical portions 51 of the first pipe 50 and 61 of the second pipe 60 are positioned extending in the vertical direction.

[0029] The second container 20 further includes a fixing member 25. The vertical portions 51 of the first pipe 50 and the second pipe 60 pass through the fixing member 25. The fixing member 25 is positioned between the bottom surface 22a of the second container 20 and the baffle plate 28 in the vertical direction. As shown in Figures 3 and 4, the fixing member 25 is a component in which a disc portion 25a and a cylindrical portion 25b are integrated, and is formed by press molding. The cylindrical portion 25b rises from the outer circumference of the disc portion 25a. The cylindrical portion 25b is welded to the inner circumferential surface of the cylindrical portion of the lower casing 22 of the second container 20. As shown in Figure 4, the disc portion 25a has a first hole 25c, a second hole 25d, and third to eighth holes. The third to eighth holes, located radially outside the first hole 25c and the second hole 25d, are circular holes through which the refrigerant passes. The first hole 25c is a circular hole through which the vertical portion 51 of the first pipe 50 passes, and its diameter is approximately the same as the outer diameter of the vertical portion 51 of the first pipe 50. The second hole 25d is a circular hole through which the vertical portion 61 of the second pipe 60 passes, and its diameter is larger than the outer diameter of the vertical portion 61 of the second pipe 60. Therefore, as shown in Figure 3, when the vertical portion 61 of the second pipe 60 passes through the second hole 25d of the disc portion 25a, an annular gap G1 exists between the vertical portion 61 of the second pipe 60 and the inner surface of the second hole 25d. Note that the outer diameter of the vertical portion 51 of the first pipe 50 and the outer diameter of the vertical portion 61 of the second pipe 60 are equal, and the diameter of the first hole 25c is smaller than the diameter of the second hole 25d.

[0030] (2-3) First pipe and second pipe As shown in Figures 2 and 3, the first pipe 50 is a pipe connecting the internal space of the second container 20 to the first compression section 11 of the first container 10, and the second pipe 60 is a pipe connecting the internal space of the second container 20 to the second compression section 12 of the first container 10. In other words, the first pipe 50 is a pipe through which the refrigerant flows from the upper space S1 of the second container 20 to the first compression section 11, and the second pipe 60 is a pipe through which the refrigerant flows from the upper space S1 of the second container 20 to the second compression section 12. The first pipe 50 and the second pipe 60 have the same diameter, with an outer diameter of 6 mm to 10 mm.

[0031] The first pipe 50 consists of a vertical section 51 extending vertically within the internal space of the second container 20, a horizontal section 53 penetrating the inside and outside of the first container 10, and an intermediate section 52 connecting the vertical section 51 and the horizontal section 53. The second pipe 60 consists of a vertical section 61 extending vertically within the internal space of the second container 20, a horizontal section 63 penetrating the inside and outside of the first container 10, and an intermediate section 62 connecting the vertical section 61 and the horizontal section 63.

[0032] As shown in Figure 3, the vertical portion 51 of the first pipe 50 and the vertical portion 61 of the second pipe 60 extend upward from the bottom surface 22a of the second container 20 toward the upper space S1 of the second container 20. The bottom surface 22a of the second container 20 has two holes and burring portions formed around these holes. Here, the two burring portions formed on the bottom surface 22a of the second container 20 are referred to as the second fixing portion F2 and the third fixing portion F3, respectively. The first pipe 50 passes through the inner hole of the third fixing portion F3, and the second pipe 60 passes through the inner hole of the second fixing portion F2. The connection portion between the intermediate portion 52 and the vertical portion 51 of the first pipe 50 is fixed to the third fixing portion F3, and the connection portion between the intermediate portion 62 and the vertical portion 61 of the second pipe 60 is fixed to the second fixing portion F2.

[0033] Furthermore, the upper end of the first pipe 50 (upper end 51a of the vertical section 51) and the upper end of the second pipe 60 (upper end 61a of the vertical section 61) are at substantially the same height position H0 (see Figure 3). Being at substantially the same height position means that the difference in height between the two 51a and 61a is less than or equal to 5% of the length of the first pipe 50 and the second pipe 60 inside the second container 20 (the length corresponding to the second distance L2 in Figure 4).

[0034] As described above, the vertical portion 61 of the second pipe 60 penetrates the second hole 25d of the disc portion 25a with a gap G1 between them. Therefore, the second pipe 60 is fixed and supported only by the second fixing portion F2 of the bottom surface 22a of the second container 20. On the other hand, the vertical portion 51 of the first pipe 50 penetrates the first hole 25c of the disc portion 25a, and the penetrating portion is fixed to the disc portion 25a. Here, the portion around the first hole 25c of the disc portion 25a that fixes the vertical portion 51 of the first pipe 50 is referred to as the first fixing portion F1 of the disc portion 25a. The first pipe 50 is fixed and supported by the third fixing portion F3 of the bottom surface 22a of the second container 20, as well as by the first fixing portion F1 of the disc portion 25a. As is evident from the fact that the first hole 25c inside the first fixing part F1 is formed in the fixing member 25 and the fixing member 25 is located above the bottom surface 22a of the second container 20, the first hole 25c and the first fixing part F1 around it are located above the second fixing part F2 on the bottom surface 22a.

[0035] In the second container 20, the first height position H1 shown in Figure 3 is higher than the second height position H2 shown in Figure 3. The first height position H1 is the height of the upper end of the first fixing part F1. The second height position H2 is the height of the upper end of the second fixing part F2.

[0036] The dimension L3 shown in Figure 3 is the value obtained by subtracting the first distance L1 from the second distance L2 shown in Figure 3. The second distance L2 is the distance from the height position of the upper end of the second fixing part F2 (second height position H2) to the upper end 61a of the vertical part 61 of the second pipe 60. The first distance L1 is the distance from the height position of the upper end of the first fixing part F1 (first height position H1) to the upper end 51a of the vertical part 51 of the first pipe 50. The difference between these second distance L2 and first distance L1 is the dimension L3 shown in Figure 3. This difference dimension L3 is 9% or more of the second distance L2. Also, the difference dimension L3 is 55% or less of the second distance L2.

[0037] (2-4) Preferred range of difference dimension L3 As described above, the dimension L3, which is the difference between the second distance L2 and the first distance L1 shown in Figure 3, is preferably 9% or more of the second distance L2 and 55% or less of the second distance L2. This range is a numerical range that the inventor arrived at from the viewpoint of suppressing resonance in the vertical portion 51 of the first pipe 50 and the vertical portion 61 of the second pipe 60.

[0038] In the compressor 6 according to this embodiment shown in Figure 3, the vertical portions 51 of the first pipe 50 and the second pipe 60 within the second container 20 are fixed at different height positions. Specifically, the vertical portion 51 of the first pipe 50 is fixed at two locations, the first fixing part F1 and the third fixing part F3 (height positions H1, H2), while the vertical portion 61 of the second pipe 60 is fixed only at the second fixing part F2 (height position H2). In the second container 20, the portion of the vertical portion 51 of the first pipe 50 above the first fixing part F1 (height position H1) stands as a cantilever beam, and the portion of the vertical portion 61 of the second pipe 60 above the second fixing part F2 (height position H2) stands as a cantilever beam. In other words, a cantilever beam of the first pipe 50 above the first fixed part F1 (with a length of the first distance L1) and a cantilever beam of the second pipe 60 above the second fixed part F2 (with a length of the second distance L2) exist within the second container 20. In order to suppress the resonance of these cantilever beams of the first pipe 50 and the second pipe 60 as much as possible, the inventor determined the range of the difference dimension L3 by the following calculation.

[0039] First, to avoid resonance between the primary eigenvalue of the cantilever beam of the longer second pipe 60 and the primary eigenvalue of the cantilever beam of the shorter first pipe 50, a 20% margin is provided in the eigenvalue ratio, and the values ​​are limited so that the eigenvalue ratio is 1.2 or greater. As shown in Figure 5, the ratio of the dimension L3 to the second distance L2 for which the eigenvalue ratio is 1.2 or greater is 0.09 or greater. As a result, the difference dimension L3 is set to 9% or greater of the second distance L2, as described above.

[0040] Next, resonance occurs between the second eigenvalue of the cantilever beam of the longer second pipe 60 and the first eigenvalue of the cantilever beam of the shorter first pipe 50 when the ratio of these two values ​​(eigenvalue ratio) is around 6.27. Furthermore, as the length of the cantilever beam of the shorter first pipe 50 decreases, and the ratio of the first distance L1 to the second distance L2 decreases, the eigenvalue ratio increases, raising concerns about resonance with the third and fourth eigenvalues. For this reason, a 20% margin is set at the eigenvalue ratio of 6.27, and the difference dimension L3 is determined so that the eigenvalue ratio is 5 or less. Specifically, as described above, the difference dimension L3 is set to be 55% or less of the second distance L2.

[0041] The first and second eigenvalues ​​(natural frequencies) were obtained by numerically analyzing the solution to the equation for the natural frequencies of a cantilever beam using the Newton-Raphson method.

[0042] (3) Features (3-1) In the compressor 6 according to this embodiment, the upper end positions of the first pipe 50 and the second pipe 60, which extend upward from the lower part of the second container 20 to the upper space S1 of the second container 20, are aligned to the same height position H0 to ensure the amount of refrigerant that can be stored in the second container 20. If the upper end of either the first pipe 50 or the second pipe 60 is at a lower position, the amount of refrigerant that can be stored in the second container 20 will decrease.

[0043] Furthermore, in the compressor 6, the height position of the upper end of the first fixing part F1 to which the first pipe 50 is fixed (first height position H1) is higher than the height position of the upper end of the second fixing part F2 to which the second pipe 60 is fixed (second height position H2) (see Figure 3). This shifts the natural frequency of the first pipe 50 extending upward from the first fixing part F1 and the natural frequency of the second pipe 60 extending upward from the second fixing part F2, thereby avoiding resonance between the first pipe 50 and the second pipe 60 and suppressing vibration of the entire compressor 6. Therefore, with this compressor 6, it is possible to suppress vibration of the first pipe 50 and the second pipe 60 while ensuring the amount of refrigerant stored in the second container 20.

[0044] (3-2) In the compressor 6 according to this embodiment, the second distance L2, which is the length of the second pipe 60 extending upward from the second fixed part F2, is 9% or more greater than the first distance L1, which is the length of the first pipe 50 extending upward from the first fixed part F1, thereby ensuring that the natural frequencies of the first pipe 50 and the second pipe 60 are reliably shifted.

[0045] (3-3) In the compressor 6 according to this embodiment, the ratio of the first distance L1, which is the length of the first pipe 50 extending upward from the first fixed part F1, to the second distance L2, which is the length of the second pipe 60 extending upward from the second fixed part F2, is kept within a predetermined range (0.91 to 0.45) (see the description above and Figure 5). In other words, the difference dimension L3 is set to 55% or less of the second distance L2. This suppresses the problem of the primary eigenvalue (natural frequency) of the first pipe 50 and the secondary or higher eigenvalues ​​of the second pipe 60 becoming too close together.

[0046] (3-4) In the compressor 6 according to this embodiment, a fixing member 25, as shown in Figure 4, is provided and fixed to the lower casing 22 of the second container 20. This eliminates the need to mold the lower casing 22 of the second container 20 into a complex shape, and also allows for a distance between the height position of the upper end of the first fixing part F1 (first height position H1) and the height position of the upper end of the second fixing part F2 (second height position H2).

[0047] (3-5) In the compressor 6 according to this embodiment, a configuration is adopted in which the first pipe, which has passed through the first hole, is fixed to a fixing member. Therefore, the fixing member can be positioned at a high location, far away from the bottom of the second container.

[0048] (3-6) In the compressor 6 according to this embodiment, a first hole 25c and a second hole 25d are formed in the disc portion 25a of the fixing member 25. The second hole 25d is located above the bottom surface 22a of the second container 20, and the second pipe 60 passes through it. With the second pipe 60 passing through the second hole 25d, an annular gap G1 exists between the second pipe 60 and the inner circumferential surface of the second hole 25d. In this way, in the second container 20 of the compressor 6, since the fixing member 25 has a second hole 25d, the vertical portion 61 of the second pipe 60 can be extended upward from the second fixing portion F2 on the bottom surface 22a of the second container 20 without having to avoid the fixing member 25.

[0049] (4) Variations (4-1) In the compressor 6 described above, a two-cylinder rotary compressor is used as the first container 10. However, the technology disclosed above can also be applied to compressors that have three or more cylinders and that transport refrigerant from the second container to the first container through three or more pipes.

[0050] (4-2) In the compressor 6 described above, the fixing member 25 shown in Figure 4 is fixed to the lower casing 22 of the second container 20. However, the fixing member and the casing of the second container may be integrated, or a fixing member extending upward from the lower casing of the second container may be used.

[0051] (4-3) While embodiments of this disclosure have been described above, it should be understood that various modifications to the form and details are possible without departing from the spirit and scope of this disclosure as described in the claims. [Explanation of Symbols]
