Description

Technical Field

[0001] This invention relates to the field of air conditioning system technology, and in particular to a compressor assembly and an air conditioning system. Background Technology

[0002] To address issues such as liquid slugging caused by liquid in the intake air of air conditioning systems, a common approach is to connect one or more liquid receivers to the intake port of the compressor cylinder. These receivers separate the liquid refrigerant from the gaseous refrigerant and introduce the gaseous refrigerant into the compressor through the intake structure. The length of the intake pipe in the intake structure has a significant impact on the compressor's intake volume. However, in existing technologies, the length of the intake structure is often fixed. When the compressor speed changes, the length of the intake pipe may become mismatched, resulting in a reduction in the compressor's intake volume and insufficient cooling capacity. Summary of the Invention

[0003] The main objective of this invention is to provide a compressor assembly and an air conditioning system that take into account the operating performance of the compressor assembly at different speeds.

[0004] To achieve the above objectives, the compressor assembly proposed in this invention includes:

[0009] In one embodiment, the suction pipe structure includes a first suction pipe and a plurality of second suction pipes. One end of the first suction pipe is connected to the air inlet, and the other end can be selectively connected to one of the second suction pipes. All of the plurality of second suction pipes are connected to the gas-liquid separator, and at least two of the plurality of second suction pipes have different lengths.

[0010] In one embodiment, the first suction tube is connected to a plurality of second suction tubes via a multi-port valve.

[0011] In one embodiment, the suction pipe structure includes a first suction pipe and a plurality of second suction pipes. One end of the first suction pipe is connected to the air inlet, and the other end is connected to the plurality of second suction pipes. The plurality of second suction pipes are all connected to the gas-liquid separator, and at least two of the plurality of second suction pipes have different lengths.

[0012] In one embodiment, the first suction pipe is connected to a plurality of second suction pipes via a multi-port pipe, and the multi-port pipe is located inside the gas-liquid separator; or, the multi-port pipe is located outside the gas-liquid separator.

[0013] In one embodiment, a plurality of second suction tubes extend into the gas-liquid separator from the bottom of the gas-liquid separator.

[0014] In one embodiment, the length of the intake tube structure is greater than 100 mm and less than 600 mm.

[0030] The present invention proposes a compressor assembly 1.

[0031] Please see Figures 1 to 3 In one embodiment of the present invention, the compressor assembly 1 includes:

[0032] Gas-liquid separator 2;

[0033] The compressor body 11 has an air inlet; and

[0034] The suction pipe structure 12 has one end connected to the air inlet and the other end connected to the gas-liquid separator 2, and the suction pipe structure 12 has at least two effective suction lengths of different lengths.

[0035] Specifically, the compressor body 11 contains a cylinder, and the air inlet is connected to the cylinder so that the gas-liquid separator 2 can introduce gaseous refrigerant into the cylinder through the air inlet via the suction pipe structure 12, allowing the cylinder to compress the gaseous refrigerant. One end of the suction pipe structure 12 is connected to the air inlet of the compressor body 11, and the other end is connected to the gas-liquid separator 2, thereby introducing gaseous refrigerant into the compressor body 11. This combined structure of the compressor body 11 and the gas-liquid separator 2 not only helps to solve the risk of liquid slugging caused by liquid carrying in the compressor body 11 during suction, but also helps to solve the oil return problem of the entire air conditioning system, especially the liquid slugging problem when rapid oil return is required during startup. Therefore, the gas-liquid separator 2 has an oil return hole at its bottom, which can be connected to the interior of the compressor body 11 through a specific oil return pipe, thereby realizing oil circulation and lubricating the compressor components; and the oil return hole can also control the oil return flow rate. Furthermore, to facilitate lubricating oil filtration, a filter structure is typically provided at the oil return hole. To facilitate installation and reduce the possibility of the oil return pipe becoming clogged due to filter clogging, in one embodiment, a filter structure is fitted to the outside of the oil return hole. The filter structure contains a filter chamber communicating with the oil return hole, and the chamber wall has filter holes, thereby effectively increasing the filtration area and reducing the possibility of the oil return hole becoming clogged. Of course, in other embodiments, a filter screen can also be directly installed inside the oil return hole.

[0036] In this embodiment, the connection between the suction pipe structure 12 and the gas-liquid separator 2 is achieved by inserting one end of the suction pipe structure 12 into the gas-liquid separator 2. That is, the suction pipe structure 12 is not directly connected to the outlet of the compressor body 11; rather, a portion of the suction pipe structure 12 serves as part of the outlet pipe of the gas-liquid separator 2. This helps reduce the length of the suction pipe structure 12 between the gas-liquid separator 2 and the compressor body 11, and also facilitates the fixing of the suction pipe structure 12 without requiring additional fixing brackets on the side of the compressor body 11. Furthermore, it helps reduce the pressure loss of the suction pipe structure 12, improving the suction capacity of the compressor body 11 and the system energy efficiency. The suction pipe structure 12 can be directly connected to the inlet via a quick-connect fitting. One end of the quick-connect fitting can be directly fixed to the compressor body, while the other end allows for quick insertion of the suction pipe structure 12, thus facilitating installation and ensuring installation stability.

[0037] Furthermore, the suction pipe structure 12 has at least two effective suction lengths of different lengths. Assuming the suction pipe structure 12 has two effective suction lengths of different lengths, designated as the first effective suction length and the second effective suction length, and that the first effective suction length and the second effective suction length are not equal. When the compressor body 11 is at a first speed, the suction pipe structure 12 can adopt the first effective suction length adapted to it; when the compressor body 11 is at a second speed, the suction pipe structure 12 can adopt the second effective suction length adapted to it. That is, the suction pipe structure 12 has at least a variety of different effective suction lengths to adapt to the speed of the motor inside the compressor body 11, thereby improving the compatibility between the suction pipe structure 12 and the compressor body 11, ensuring the suction volume of the compressor body 11 at different speeds, thus ensuring the cooling effect of the compressor, and taking into account the working performance of the compressor assembly 1 at different speeds. The length of the air intake pipe structure 13 can be varied. In other embodiments, the air intake pipe structure 12 can also have three or more effective air intake lengths. Designers can design accordingly based on the actual needs of the air conditioning system.

[0038] It should be noted that the effective suction length of the suction pipe structure 12 can be equal to or different from the length of the suction pipe structure 12 itself. Furthermore, at the first rotational speed, the suction pipe structure 12 can employ a first effective suction length that is compatible with it. This does not mean that the suction pipe of the suction pipe structure 12 only has one effective suction length for transporting gaseous refrigerant. It may only have a suction pipe with this first effective suction length for transporting gaseous refrigerant; or it may have a suction pipe with multiple effective suction lengths (such as a suction pipe with both first and second effective lengths) for transporting gaseous refrigerant. As long as one of the multiple effective suction lengths of the suction pipe is compatible with the compressor body 11, the purpose of adapting the suction pipe structure 12 to the compressor body 11 can be achieved.

[0039] That is, the suction pipe structure 12 can have at least two different effective suction lengths, so that as the speed of the compressor body 11 changes, different lengths of suction pipes can be selected for conduction or the length of the suction pipe can be changed to adapt to the compressor; or the suction pipe structure itself can have multiple suction pipes of different lengths, and multiple suction pipes of different lengths work together, so that no matter what speed the compressor body 11 uses, there is a suction pipe of matching length to participate in the suction work.

[0040] In one embodiment, the gas-liquid separator 2 is installed on one axial side of the compressor body 11, thereby facilitating the overall assembly of the compressor assembly 1 and controlling the overall length of the suction pipe structure 12. To facilitate the installation of the gas-liquid separator 2, in one embodiment, a fixing bracket can be provided on one side of the compressor body 11 to fix the gas-liquid separator 2, thereby ensuring the stability of the gas-liquid separator installation. The fixing bracket can be welded to the compressor body 11, and can be clamped to the periphery of the gas-liquid separator in the form of clamps to improve installation stability and facilitate the installation of the gas-liquid separator.

[0041] In other embodiments, the compressor body 11 and the gas-liquid separator 2 can also be set independently. This structure helps to reduce the radial dimension of the compressor body 11, making the deviation between the center of gravity of the compressor body 11 and the axis of its internal motor very small, thereby reducing noise caused by unbalanced vibration of the compressor body 11. However, this structure often requires a connecting bracket to be set on the side of the compressor body 11 to fix the suction pipe structure 12.

[0042] Please see Figure 1In one embodiment of the present invention, the length of the inhalation tube structure 12 is variably configured so that the inhalation tube structure 12 has at least two effective inhalation lengths. Specifically, the effective inhalation length of the inhalation tube structure 12 is changed by altering its own length.

[0043] In one embodiment, the suction pipe structure 12 is configured as a telescopic suction pipe, thereby achieving different effective suction lengths through its own expansion and contraction. In this case, the suction pipe structure 12 can precisely adjust its size according to the rotational speed of the compressor body 11. For example, the telescopic suction pipe includes two slidably fitted pipe segments. The length of the suction pipe structure is adjusted by the mutual sliding between the two pipe segments, thereby changing the effective suction length of the suction pipe structure. In other embodiments, the telescopic suction pipe can also be configured as a corrugated pipe, thereby enabling the suction pipe structure 12 to contract.

[0044] In another embodiment, see again Figure 1 The suction pipe structure 12 includes a first suction pipe 121 and a plurality of second suction pipes 122. One end of the first suction pipe 121 is connected to the air inlet, and the other end can be selectively connected to one of the second suction pipes 122. The plurality of second suction pipes 122 are all connected to the gas-liquid separator 2, and at least two of the plurality of second suction pipes 122 have different lengths. Specifically, one end of the first suction pipe 121 is connected to the air inlet, that is, the first suction pipe 121 is a pipe section close to the compressor body 11, which is directly connected to the air inlet of the compressor body 11. Multiple second suction pipes 122 can all be connected to the gas-liquid separator 2, and at least two of the multiple second suction pipes 122 have different lengths, so that the suction pipe structure 12 has at least two different lengths. The first suction pipe 121 can be selectively connected to the second suction pipe 122, so that the suction pipe structure 12 has different effective suction lengths by connecting different second suction pipes 122 through the first suction pipe 121, thereby facilitating the switching of suction pipe structures 12 with different effective suction lengths.

[0045] The second suction pipe 122 can be directly connected to the outlet end of the gas-liquid separator 2, or it can be directly introduced into the gas-liquid separator 2, that is, it serves as part of the outlet pipe of the gas-liquid separator 2. The structure of the gas-liquid separator 2 can be as follows: the gas-liquid separator 2 includes a gas-liquid separation chamber, an inlet pipe located at the upper part of the gas-liquid separation chamber, and multiple second suction pipes 122 extending from the lower part of the gas-liquid separation chamber. Each of the multiple second suction pipes 122 is offset from one end of the inlet pipe in the gas-liquid separation chamber along the axial direction of the gas-liquid separator. Refrigerant is injected into the gas-liquid separator from the inlet pipe, where the liquid refrigerant sinks to the bottom of the gas-liquid separation chamber, and the gaseous refrigerant floats. The floating gaseous refrigerant can flow into the gas-liquid separator from the opening of the second suction pipe 122 within the gas-liquid separation chamber, and then flow from the second suction pipe 122 to the first suction pipe 121 and then to the inlet of the compressor body 11. Of course, the structure of the gas-liquid separator 2 is not limited to this. For example, the second suction pipe can also extend into the gas-liquid separation chamber through the top of the gas-liquid separator 2. As long as the gas-liquid separation effect can be achieved through the gas-liquid separator 2, it is within the protection scope of this solution.

[0046] The second suction pipe 122 can be connected to the first suction pipe 121 via a quick-connect fitting. Therefore, valves can be installed on each of the multiple second suction pipes 122. When the corresponding second suction pipe 122 is not needed, the corresponding valve can be closed to block it. Alternatively, the second suction pipe 122 can be directly separated from the first suction pipe 121, and the corresponding second suction pipe 122 can be blocked. In other embodiments, the first suction pipe 121 can also be integrally formed with the multiple second suction pipes 122.

[0047] In other embodiments, the first inhalation tube 121 and the plurality of second inhalation tubes 122 can also be connected by a switching assembly. The switching assembly switches the connection between the first inhalation tube 121 and one of the plurality of second inhalation tubes 122, thus eliminating the need to repeatedly disassemble the first inhalation tube 121 and the second inhalation tubes 122. This facilitates the connection between the first inhalation tube 121 and the second inhalation tubes 122 and simplifies the overall structure of the inhalation tube structure 12. For example, the first inhalation tube 121 is connected to the plurality of second inhalation tubes 122 via a multi-way valve 123.

[0048] The number of second air intake tubes 122 is at least two, but can also be three, four, five, six, etc. Understandably, the more second air intake tubes 122 there are, the more types of lengths that can be configured for the air intake structure 12. However, too many second air intake tubes 122 can also cause the air intake section of the air intake structure 12 to be too dispersed. Therefore, an appropriate number of second air intake tubes can be selected according to actual needs. Furthermore, the lengths of the multiple second air intake tubes 122 can all be unequal, or only partially unequal.

[0049] In another embodiment of the present invention, the suction pipe structure 12 includes a first suction pipe 121 and a plurality of second suction pipes 122. One end of the first suction pipe 121 is connected to the air inlet, and the other end is connected to the plurality of second suction pipes 122. The plurality of second suction pipes 122 are all connected to the gas-liquid separator 2, and at least two of the plurality of second suction pipes 122 have different lengths. Specifically, one end of the first suction pipe 121 is connected to the air inlet, that is, the first suction pipe 121 is a pipe segment close to the compressor body 11, which is directly connected to the air inlet of the compressor body 11. The plurality of second suction pipes 122 can all be connected to the air outlet of the gas-liquid separator 2, and at least two of the plurality of second suction pipes 122 have different lengths. The first suction pipe 121 can simultaneously connect to the plurality of second suction pipes 122, thereby allowing the suction pipe structure 12 to be divided into multiple branches, so that the suction pipe structure 12 can be divided into multiple branches. 2. It simultaneously features multiple effective suction lengths of varying lengths. When the refrigerant enters the gas-liquid separator 2, it can simultaneously enter the first suction pipe 121 from the second suction pipe 122 of different lengths, and then enter the cylinder of the compressor body 11. This eliminates the need for additional control or switching structures to control the connection between the first and second suction pipes 121 and 122. It also ensures increased suction volume at different operating speeds of the compressor body 11, preventing a complete deterioration of suction volume at certain speeds, which could lead to insufficient cooling capacity of the compressor body 11. The second suction pipe 122 can be directly connected to the outlet end of the gas-liquid separator 2, or it can be directly connected to the gas-liquid separator 2, serving as part of the outlet pipe of the gas-liquid separator 2.

[0050] The first inhalation tube 121 is connected to multiple second inhalation tubes 122 via a multi-port tube, thereby facilitating the connection between the first inhalation tube 121 and the second inhalation tubes 122. In one embodiment, see... Figure 2 The multi-port pipe is located inside the gas-liquid separator 2; in another embodiment, see Figure 3 The multi-port pipe is located outside the gas-liquid separator 2. That is, the insertion depth of the suction pipe structure 12 into the gas-liquid separator 2 can be adjusted according to actual needs. This solution does not limit this.

[0051] Please see Figures 1 to 3 In an embodiment of the present invention, a plurality of second suction pipes 122 extend into the gas-liquid separator 2 from the bottom of the gas-liquid separator 2. That is, the second suction pipe 122 is connected to the end of the gas-liquid separator 2 near the air inlet, thereby facilitating the close connection between the suction pipe structure 12 and the gas-liquid separator 2. Moreover, this connection method often does not require additional fixing of the suction pipe structure 12, thereby facilitating the overall assembly of the compressor assembly 1.

[0052] Please refer to the table below. According to simulation software tests, the length of the inhalation tube structure 12 and its resonant frequency are approximately related as follows: the longer the inhalation tube structure 12, the lower its resonant frequency tends to be. Designers can also find the resonant frequencies of inhalation tube structures 12 of different lengths in the table below (the resonant frequencies of inhalation tube structures 12 of different lengths are usually obtained through simulation software testing). Please refer to... Figure 4 , Figure 4 Line graphs showing the effect of suction pipe structure 12 on the cooling capacity under different compressor body 11 rotation frequencies are used. By presetting the length of suction pipe structure 12, simulation tests are conducted to obtain the corresponding cooling capacity data under different compressor body 11 rotation frequencies, and the corresponding line graphs are plotted. Figure 4 The document presents two inhalation tube structures of varying lengths: a first inhalation tube structure and a second inhalation tube structure. The first inhalation tube structure has a length of 510 mm, which, based on the table below, can be deduced to be slightly less than 90 Hz. The second inhalation tube structure has a length of 350 mm, which, based on the table below, can be deduced to be approximately equal to 130 Hz. (Combined with...) Figure 4 It was found that when the first suction pipe structure was at approximately 90Hz, its cooling capacity increased significantly; when the second suction pipe structure was at 130Hz, the cooling capacity also increased significantly. Therefore, it can be inferred that when the length of the suction pipe structure 122 is near the resonant frequency, the corresponding cooling capacity of the compressor body 11 increases significantly. Therefore, to increase the cooling capacity of the compressor body 11, it is preferable to have a suction pipe structure 12 of a corresponding length that can resonate with the compressor body 11.

[0053] Generally, the rotational frequency of a variable frequency compressor is typically between 30Hz and 120Hz. According to the table below, when the length of the suction pipe structure 12 is between 375mm and 1500mm, the suction pipe structure 12 easily resonates with the rotational frequency of the compressor body 11, resulting in a larger cooling capacity and better compressor performance. However, in practical applications, the length of the suction pipe structure 12 is often less than the length calculated in the simulation. Considering the trend towards higher compressor speeds, installation deviations of the compressor body 11, and differences in sound velocity of different refrigerants, in the embodiments of this invention, the length of the suction pipe structure 12 is greater than 100mm and less than 600mm. This helps to achieve a larger suction volume for the compressor body 11 within the operating frequency range of 30Hz to 160Hz, thereby improving the cooling capacity of the air conditioning system and further reducing the pressure loss caused by the suction pipe structure 12, thus improving the suction volume of the compressor body 11 and the energy efficiency of the air conditioning system.

[0055] Table of the relationship between the length of the inhalation tube structure and its resonant frequency

[0056] The length of the suction pipe structure 12 can be 101mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, and 599mm, etc. Of course, the length of the suction pipe structure 12 can also be greater than or equal to 600mm, which helps to improve the performance of the compressor assembly 1 over a wider speed range.

[0057] In one embodiment, the compressor assembly 1 has two suction pipe structures 12, and the two suction pipe structures 12 are of equal length. That is, the compressor body 11 has two air inlets, meaning the compressor body 11 is configured in a dual-suction mode. The equal length of the two suction pipe structures 12 allows the pressure pulsations at the air inlets to cancel each other out due to their opposite phases, thereby achieving optimal suction pressure pulsation. To ensure the cancellation effect, the material, thickness, and diameter of the two suction pipe structures 12 should be identical, and their extension directions should also be identical. The structures of the two suction pipe structures 12 are also identical, thus… Of course, in other embodiments, the lengths of the two suction pipe structures 12 may be unequal, and the structures of the two suction pipe structures 12 may also be different. For example, both suction pipe structures 12 may include a first suction pipe 121 and a plurality of second suction pipes 122, all of which are connected to the gas-liquid separator 2, and at least two of the plurality of second suction pipes 122 may have different lengths. One end of each of the two first suction pipes 121 may be connected to the air inlet, and the other end of one of the two first suction pipes 121 may be connected to the plurality of second suction pipes 122. The other end of the other of the two first suction pipes 121 may be selectively connected to a second suction pipe 122. Alternatively, one of the two suction pipe structures 12 may be configured as a structure in which the first suction pipe 121 is connected to the plurality of second suction pipes 122, and the other may be configured as a retractable suction pipe.

[0058] In other embodiments, the compressor body 11 may also have two or more air inlets. For example, the compressor body 11 has three air inlets, and the number of corresponding suction pipe structures 12 is also 3; or, the compressor body 11 has only one air inlet, and the number of corresponding suction pipe structures 12 is 1.

[0059] The present invention also proposes an air conditioning system, which includes a compressor assembly 1. The specific structure of the compressor assembly 1 is as described in the above embodiments. Since this air conditioning system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The compressor body 11 is fixedly installed within the air conditioning system. Therefore, mounting feet can be provided on the compressor body 11 to achieve stable fixed installation.

[0060] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the protection scope of the present invention.
