Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to an air conditioner. Background Technology

[0002] The function of an air conditioner is to regulate temperature and humidity, providing a comfortable temperature and humidity experience. Traditional air conditioners regulate humidity by controlling the temperature of the evaporator. After the indoor air exchanges heat with the evaporator, its temperature drops below the dew point temperature, causing the moisture in the air to condense and precipitate, thus reducing the humidity content of the air and achieving the purpose of dehumidification.

[0003] However, in some application scenarios, the indoor temperature is relatively low, requiring dehumidification while avoiding excessive temperature adjustment to prevent a drastic temperature drop during dehumidification, which could result in a damp and cold feeling. In such cases, simultaneous temperature and humidity regulation is necessary, necessitating both increased dehumidification capacity and control of the air conditioner's outlet temperature. Current solutions sometimes increase the outlet temperature by adding electric heating during dehumidification, while others regulate it by diverting outdoor heat into the room. However, from an energy consumption perspective, all these solutions represent significant energy waste and reduce the air conditioner's energy efficiency.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To address at least one of the aforementioned problems in the prior art, namely, the high energy consumption of existing air conditioners without cooling and dehumidification processes, this application provides an air conditioner comprising a compressor, a condenser, a throttling element, and an evaporator. The air conditioner also includes a flow distribution device comprising a housing and a mixing inlet pipe, a gas outlet pipe, and a liquid outlet pipe disposed on the housing. The evaporator comprises an internal exhaust heat exchange pipe and an external exhaust heat exchange pipe. The compressor's exhaust port is connected to the condenser's inlet, the condenser's outlet is connected to the throttling element's inlet, the mixing inlet pipe is connected to the throttling element's outlet, the gas outlet pipe is connected to one of the internal exhaust heat exchange pipe's inlet and the external exhaust heat exchange pipe's inlet, the liquid outlet pipe is connected to the other of the internal exhaust heat exchange pipe's inlet and the external exhaust heat exchange pipe's inlet, and the outlets of both the internal and external exhaust heat exchange pipes are simultaneously connected to the compressor's suction port.

[0006] In the preferred embodiment of the above-mentioned air conditioner, the gas outlet pipe is connected to the inlet of the internal exhaust heat exchange pipe, and the liquid outlet pipe is connected to the inlet of the external exhaust heat exchange pipe.

[0007] In the preferred embodiment of the above-mentioned air conditioner, the mixing inlet pipe is disposed on the bottom surface of the outer casing, the gas outlet pipe and the liquid outlet pipe are both disposed on the top surface of the outer casing, a separation pipe is disposed inside the outer casing, the two ends of the separation pipe are respectively connected to the mixing inlet pipe and the liquid outlet pipe, the separation pipe is provided with micropores, the separation pipe is connected to the gas outlet pipe through the micropores, and the flow divider is configured to allow a portion of the gaseous refrigerant in the gas-liquid mixed refrigerant entering through the mixing inlet pipe to pass through the micropores and flow out through the gas outlet pipe, while the remaining gas-liquid mixed refrigerant flows out through the liquid outlet pipe.

[0008] In the preferred embodiment of the above-mentioned air conditioner, the mixing inlet pipe is located in the middle of the bottom surface, and the liquid outlet pipe is located in the middle of the top surface.

[0009] In the preferred embodiment of the above-mentioned air conditioner, the diameters of the mixing inlet pipe and the liquid outlet pipe are both larger than the diameter of the separating pipe.

[0010] In the preferred embodiment of the above-mentioned air conditioner, the micropores are disposed in the middle of the separation tube along its length.

[0011] In the preferred embodiment of the above-mentioned air conditioner, two micropores are provided, and the two micropores are arranged opposite each other along the radial direction of the separator tube; and / or

[0012] The diameter of the micropores is 0.3-0.5 mm.

[0013] In the preferred embodiment of the above-mentioned air conditioner, the outer casing is truncated cone-shaped.

[0014] In the preferred embodiment of the above-mentioned air conditioner, multiple gas outlet pipes are provided, and the multiple gas outlet pipes are evenly distributed circumferentially along a concentric circle with the outer circle of the top surface of the outer casing.

[0015] In the preferred embodiment of the above-described air conditioner, the radius of the outer circle of the top surface of the outer casing is larger than the radius of the outer circle of the bottom surface of the outer casing; and / or

[0016] The ratio of the radius of the concentric circles to the radius of the outer circle of the top surface of the outer shell is 0.5-0.75.

[0017] It should be noted that, in the preferred technical solution of this application, the air conditioner includes a compressor, a condenser, a throttling element, and an evaporator. The air conditioner also includes a flow distribution device, which includes a housing and a mixing inlet pipe, a gas outlet pipe, and a liquid outlet pipe disposed on the housing. The evaporator includes an internal exhaust heat exchange pipe and an external exhaust heat exchange pipe. The exhaust port of the compressor is connected to the inlet of the condenser, the outlet of the condenser is connected to the inlet of the throttling element, the mixing inlet pipe is connected to the outlet of the throttling element, the gas outlet pipe is connected to one of the inlets of the internal exhaust heat exchange pipe and the external exhaust heat exchange pipe, the liquid outlet pipe is connected to the other of the inlets of the internal exhaust heat exchange pipe and the external exhaust heat exchange pipe, and the outlets of the internal exhaust heat exchange pipe and the external exhaust heat exchange pipe are simultaneously connected to the suction port of the compressor.

[0018] The air conditioner disclosed in this application achieves dehumidification without cooling by installing a flow-dividing device upstream of the evaporator and connecting the gas outlet and liquid outlet of the flow-dividing device to one of the internal and external exhaust heat exchange tubes, respectively. This reduces the energy consumption of the air conditioner. Specifically, during the cooling process, the refrigerant, after passing through the throttling element, becomes a gas-liquid mixture. After entering the flow-dividing device, the gaseous and liquid refrigerants are discharged from the gas outlet and liquid outlet, respectively, and enter the internal and external exhaust heat exchange tubes, respectively. The heat exchange tube containing the gaseous refrigerant has a higher evaporation temperature, which, although lower than the dew point temperature, has a smaller temperature difference with the air dew point, resulting in lower dehumidification capacity and higher outlet air temperature. The heat exchange tube containing the liquid refrigerant has a lower temperature, lower than the dew point temperature, and a larger temperature difference with the air dew point, resulting in stronger dehumidification capacity. It can reduce the outlet air temperature while simultaneously dehumidifying. The air outlets from the two heat exchange tubes mix, achieving not only dual control of temperature and humidity but also ensuring that the final exhaust air temperature is cool but not cold. Furthermore, this method of dehumidification without cooling does not introduce any other heating devices, thus avoiding energy waste.

[0019] Furthermore, by connecting the gas outlet pipe to the inlet of the internal heat exchange pipe and the liquid outlet pipe to the inlet of the external heat exchange pipe, the air conditioner of this application achieves the liquid refrigerant on the outside and the gaseous refrigerant on the inside during cooling. During the external dehumidification process, the condensed water droplets are blocked by the internal evaporator, which can avoid the phenomenon of water blowing from the indoor unit.

[0020] Furthermore, the flow divider is configured such that a portion of the gaseous refrigerant in the gas-liquid mixture entering through the mixing inlet pipe passes through micropores and flows out through the gas outlet pipe, while the remaining gas-liquid mixture flows out through the liquid outlet pipe. This allows some of the refrigerant to flash back into gaseous form due to pressure drop and friction after entering the mixing inlet pipe at high speed. The flashed gaseous refrigerant, resisted by the liquid refrigerant ahead, passes through the micropores and flows out through the gas outlet pipe, while most of the liquid refrigerant continues to flow forward under the centrifugal force of the high-speed liquid flow, thus achieving effective separation of the gas-liquid mixture. Secondly, compared to the limitations of existing gas-liquid separators with multiple internal tubes that hinder miniaturization, this application features only one separation tube within the cavity, with both ends connected to the mixing inlet pipe and the liquid outlet pipe, making product miniaturization easier. Moreover, the miniaturized flow divider can be directly integrated with the evaporator, for example, by being installed directly within the indoor unit casing, without requiring a separate device.

[0021] Furthermore, the mixing inlet pipe is located in the middle of the bottom surface, and the liquid outlet pipe is located in the middle of the top surface. This simplifies the product manufacturing process, allows the separator pipe to be a straight pipe, and minimizes pressure loss along the flow path.

[0022] Furthermore, by setting the diameters of both the mixing inlet pipe and the liquid outlet pipe to be larger than the diameter of the separator pipe, the flow velocity of the gas-liquid mixed refrigerant in the separator pipe can be increased, the pressure drop of the refrigerant can be reduced, and the gas-liquid separation effect can be guaranteed.

[0023] Furthermore, by placing the micropores in the middle of the separation tube along its length, a better gas-liquid separation effect can be obtained.

[0024] Furthermore, by setting up multiple gas outlet pipes, the separation amount of gaseous refrigerant can be guaranteed.

[0025] Furthermore, by making the outer shell truncated cone-shaped with the radius of the outer circle of the top surface being larger than the radius of the outer circle of the bottom surface, the installation space of the diversion device can be saved, making the installation method more flexible, and reducing pressure drop and refrigerant flow noise.

[0034] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although this embodiment is described in conjunction with a wall-mounted air conditioner, this is not intended to limit the scope of protection of this application. Those skilled in the art can apply this application to other application scenarios without departing from the principles of this application. For example, this application can also be applied to cabinet air conditioners, recessed air conditioners, etc.

[0035] It should be noted that in the description of this application, terms such as "upper," "lower," "vertical," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] First refer to Figure 1 and Figure 2 This paper describes the air conditioner described in this application. Among other things, Figure 1 This is a system diagram of the air conditioner of this application; Figure 2 This is a cross-sectional view of the diversion device of this application.

[0038] like Figure 1 and Figure 2 As shown, to address the high energy consumption problem of existing air conditioners that do not have a cooling and dehumidification process, the wall-mounted air conditioner of this application includes a compressor 1, a condenser 2, a throttling element 3, an evaporator 4, and a flow distribution device 6. The flow distribution device 6 includes a housing 61 and a mixing inlet pipe 62, a gas outlet pipe 63, and a liquid outlet pipe 64 disposed on the housing 61. The evaporator 4 includes an internal exhaust heat exchange pipe 41 and an external exhaust heat exchange pipe 42. In the connected state, the exhaust port of the compressor 1 is connected to the inlet of the condenser 2, the outlet of the condenser 2 is connected to the inlet of the throttling element 3, the mixing inlet pipe 62 is connected to the outlet of the throttling element 3, the gas outlet pipe 63 is connected to one of the inlets of the internal exhaust heat exchange pipe 41 and the external exhaust heat exchange pipe 42, the liquid outlet pipe 64 is connected to the other of the inlets of the internal exhaust heat exchange pipe 41 and the external exhaust heat exchange pipe 42, and the outlets of the internal exhaust heat exchange pipe 41 and the external exhaust heat exchange pipe 42 are simultaneously connected to the suction port of the compressor 1.

[0039] Under the above configuration, when the air conditioner operates in cooling mode, the high-temperature, high-pressure gaseous refrigerant discharged from compressor 1 enters condenser 2 for heat exchange and liquefaction, becoming medium-temperature, high-pressure liquid refrigerant. Subsequently, the liquid refrigerant enters throttling element 3 for throttling, becoming low-temperature, low-pressure gas-liquid two-phase refrigerant. This low-temperature, low-pressure gas-liquid two-phase refrigerant then enters separation pipe 65 from mixing inlet pipe 62. In separation pipe 65, the liquid refrigerant, under centrifugal force, flows directly through liquid outlet pipe 64 to one of the inner exhaust heat exchange pipe 41 and outer exhaust heat exchange pipe 42. A portion of the gaseous refrigerant flashes out and passes through micropore 66, then flows out through gas outlet pipe 63 to the other of the inner exhaust heat exchange pipe 41 and outer exhaust heat exchange pipe 42. Simultaneously, the refrigerant in both inner exhaust heat exchange pipe 41 and outer exhaust heat exchange pipe 42 undergoes heat exchange with indoor air, achieving evaporation and becoming gaseous refrigerant. The gaseous refrigerant returns to compressor 1 from the suction port.

[0040] By setting a diversion device 6 upstream of the evaporator 4, and connecting the gas outlet pipe 63 and liquid outlet pipe 64 of the diversion device 6 to one of the internal exhaust heat exchange pipe 41 and the external exhaust heat exchange pipe 42 respectively, dehumidification without cooling can be achieved, thus reducing the energy consumption of the air conditioner. Specifically, during the refrigeration process, the refrigerant passing through the throttling element 3 becomes a gas-liquid mixture. This mixture then enters the distribution device 6, where the gaseous and liquid refrigerants are discharged through the gas outlet pipe 63 and liquid outlet pipe 64, respectively, and enter the inner exhaust heat exchange pipe 41 and the outer exhaust heat exchange pipe 42. The heat exchange pipe containing the gaseous refrigerant has a higher evaporation temperature, which, although lower than the dew point temperature, has a smaller temperature difference with the air dew point, resulting in lower dehumidification capacity and a higher outlet air temperature. Conversely, the heat exchange pipe containing the liquid refrigerant has a lower temperature, lower than the dew point temperature, and a larger temperature difference with the air dew point, resulting in stronger dehumidification capacity. This allows for both lowering the outlet air temperature and dehumidification. The mixing of the outlet air from the two heat exchange pipes not only achieves dual temperature and humidity control but also ensures that the final exhaust air temperature is cool without being cold. Furthermore, this dehumidification method without cooling does not introduce any other heating devices, thus avoiding energy waste.

[0041] The following reference Figures 1 to 4 A preferred embodiment of the air conditioner of this application will be described. Figure 3 This is a diagram showing the refrigerant flow path of the diversion device in this application; Figure 4 This is a top view of the diversion device of this application.

[0042] like Figure 1 As shown, in a preferred embodiment, the air conditioner is a wall-mounted air conditioner, which includes an indoor unit and an outdoor unit. The outdoor unit is equipped with a compressor 1, a condenser 2, an outdoor fan, a throttling element 3, etc., and the indoor unit is equipped with an evaporator 4, an indoor fan, and a distribution device 6, etc.

[0043] The evaporator 4 is located outside the internal fan and includes two rows of heat exchange tubes: an inner heat exchange tube 41 and an outer heat exchange tube 42. The inlet of the inner heat exchange tube 41 and the inlet of the outer heat exchange tube 42 are connected to one of the gas outlet pipe 63 and the liquid outlet pipe 64, respectively. The outlets of the inner heat exchange tube 41 and the outer heat exchange tube 42 converge at a manifold and then connect to the suction port of the compressor 1. Both the inner heat exchange tube 41 and the outer heat exchange tube 42 include two flow paths. Taking the outer heat exchange tube 42 as an example, its inlet is located in the middle of the outer heat exchange tube 42. After the refrigerant enters through the inlet, it flows along the upper and lower flow paths and then converges at the manifold. The inner heat exchange tube 41 is arranged similarly and will not be described further. In this application, "internal exhaust" and "external exhaust" are defined relative to the position of the internal fan. The pipeline closer to the internal fan is the internal exhaust heat exchange pipe 41, and the pipeline farther away from the internal fan is the external exhaust heat exchange pipe 42.

[0044] See Figures 2 to 4In a preferred embodiment, the diversion device 6 includes a housing 61, which is an inverted frustum shape, meaning the radius of the outer circle of the top surface of the housing 61 is larger than the radius of the outer circle of the bottom surface. A cavity is formed inside the housing 61. A mixing inlet pipe 62 is provided on the bottom surface of the housing 61, and the mixing inlet pipe 62 is connected to the outlet of the throttling element 3. A gas outlet pipe 63 and a liquid outlet pipe 64 are provided on the top surface of the housing 61. The gas outlet pipe 63 is connected to the inlet of the internal exhaust heat exchange pipe 41, and the liquid outlet pipe 64 is connected to the inlet of the external exhaust heat exchange pipe 42. A separation pipe 65 is provided inside the cavity. The two ends of the separation pipe 65 are connected to the mixing inlet pipe 62 and the liquid outlet pipe 64, respectively, and the separation pipe 65 has micropores 66.

[0045] Preferably, see Figure 2 The mixing inlet pipe 62 is located in the middle of the bottom surface, and the liquid outlet pipe 64 is located in the middle of the top surface. The separation pipe 65 is a straight pipe, and its two ends are directly connected to the mixing inlet pipe 62 and the liquid outlet pipe 64, respectively. Regarding the pipe diameter, the diameter of the mixing inlet pipe 62 (i.e.,...) Figure 2 a) and the diameter of the liquid outlet pipe 64 (i.e. Figure 2 In section b), all diameters are greater than those of the separator 65 (i.e., ...). Figure 2 (c) In one specific embodiment, the length of the separation tube 65 can be any value between 35-38 mm, the diameter of the mixing inlet tube 62 can be any value between 6.35-8.5 mm, the diameter of the liquid outlet tube 64 can be any value between 4.5-6.35 mm, and the diameter of the separation tube 65 can be any value between 4.0-4.5 mm.

[0046] See Figure 2 and Figure 4 Multiple gas outlet pipes 63 are provided. In this application, two gas outlet pipes 63 are provided. The two gas outlet pipes 63 are evenly distributed circumferentially along concentric circles with the outer circle of the top surface of the outer shell 61, so that the center of the cross-section of the two gas outlet pipes 63 and the center of the cross-section of the liquid outlet pipe 64 are connected by a straight line. The diameter of the two gas outlet pipes 63 (i.e., Figure 2 The values ​​of 'd' in the diagram are equal, and both are equal to the diameter of the liquid outlet pipe 64. The radii of the concentric circles (i.e.,...) Figure 5 The radius of the outer circle of the top surface of the outer shell 61 (i.e., r) is the radius of the outer circle of the top surface of the outer shell 61. Figure 5 The ratio of R to R is 0.5-0.75. In one specific embodiment, the radius of the outer circle of the top surface of the outer shell 61 can be any value between 12-15 mm, and the radius of the concentric circles can be any value between 6-9 mm.

[0047] See back Figure 2Two micro-holes 66 are provided, arranged radially opposite to each other along the connecting tube, and located at the middle of the separation tube 65 along its length. In this application, the diameter of the micro-holes 66 is 0.3-0.5 mm, and the line connecting the axes of the two micro-holes 66 is parallel to the line connecting the centers of the cross-sections of the two gas outlet tubes 63 and lies in the same vertical plane. In other words, the opening direction of the two micro-holes 66 is exactly towards the axial direction of the two gas outlet tubes 63.

[0048] See Figure 3 In the above configuration, when the gas-liquid mixed refrigerant enters the separation pipe 65 through the mixing inlet pipe 62, most of the liquid refrigerant continues to flow forward under the centrifugal force of the high-speed liquid flow and eventually flows out through the liquid outlet pipe 64. Meanwhile, some refrigerant flashes into gaseous refrigerant due to pressure drop and friction. This gaseous refrigerant, resisted by the liquid refrigerant ahead, passes through the micropores 66 and flows out through the gas outlet pipe 63, thus achieving effective separation of the gas-liquid mixed refrigerant.

[0049] The air conditioner of this application connects the gas outlet pipe 63 to the inlet of the internal exhaust heat exchange pipe 41 and the liquid outlet pipe 64 to the inlet of the external exhaust heat exchange pipe 42. This allows the air conditioner to achieve liquid refrigerant on the outside and gaseous refrigerant on the inside during cooling. During the dehumidification process on the outside, the water droplets condensed are blocked by the internal evaporator 4, which can prevent the indoor unit from blowing water.

[0050] The diversion device 6 is configured such that a portion of the gaseous refrigerant in the gas-liquid mixture entering through the mixing inlet pipe 62 passes through the micropores 66 and flows out through the gas outlet pipe 63, while the remaining gas-liquid mixture flows out through the liquid outlet pipe 64. This allows the gas-liquid mixture to flash back into gaseous form after entering the mixing inlet pipe 62 at high speed due to pressure drop and friction. The flashed gaseous refrigerant, resisted by the liquid refrigerant ahead, passes through the micropores 66 and flows out through the gas outlet pipe 63, while most of the liquid refrigerant continues to flow forward under the centrifugal force of the high-speed liquid flow, thus achieving effective separation of the gas-liquid mixture. Furthermore, based on the aforementioned dimensional parameters, compared to the shortcomings of existing gas-liquid separators with multiple internal tubes that hinder miniaturization, this application's cavity contains only one separation tube 65, with both ends connected to the mixing inlet pipe 62 and the liquid outlet pipe 64, making product miniaturization easier to achieve. Furthermore, the miniaturized flow divider 6 can be directly integrated with the evaporator 4, for example, by being installed directly inside the indoor unit casing, without requiring a separate device. The mixing inlet pipe 62 is located in the middle of the bottom surface, and the liquid outlet pipe 64 is located in the middle of the top surface, simplifying the manufacturing process and allowing the separator pipe 65 to be a straight pipe, minimizing pressure loss along the pipe. By setting the diameters of both the mixing inlet pipe 62 and the liquid outlet pipe 64 to be larger than the diameter of the separator pipe 65, the flow velocity of the gas-liquid mixed refrigerant within the separator pipe 65 can be increased, reducing the refrigerant pressure drop and ensuring effective gas-liquid separation. By placing the micropores 66 in the middle of the length of the separator pipe 65, a better gas-liquid separation effect can be achieved. The multiple gas outlet pipes 63 ensure the separation volume of gaseous refrigerant. The frustum-shaped outer casing 61, with the radius of the top outer circle larger than the radius of the bottom outer circle, saves space for the flow divider 6, allowing for more flexible installation and reducing pressure drop and refrigerant flow noise.

[0051] It should be noted that the above preferred embodiments are merely illustrative of the principles of this application and are not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can adjust the above settings to make this application applicable to more specific application scenarios.

[0052] For example, in an alternative embodiment, although the air conditioner of this application is described in conjunction with a single-cooling type air conditioner, it is clear that the diversion device 6 of this application can also be applied to an air conditioner with cooling and heating functions.

[0053] For example, although the gas outlet pipe 63 is connected to the inlet of the internal heat exchange pipe 41 and the liquid outlet pipe 64 is connected to the inlet of the external heat exchange pipe 42 in this application, this arrangement is not fixed. Those skilled in the art can change it, and the same effect of dehumidification without cooling can be achieved.

[0054] For example, in another alternative embodiment, although in the diversion device 6 of this application, the mixing inlet pipe 62 is located in the middle of the bottom surface and there is only one of it, and the liquid outlet pipe 64 is located in the middle of the top surface and there is also only one of it, and the separation pipe 65 is a straight pipe with the diameters of both the mixing inlet pipe 62 and the liquid outlet pipe 64 being larger than the diameter of the separation pipe 65, this is not intended to limit the scope of protection of this application. In other embodiments, those skilled in the art can change the above-mentioned arrangement according to the specific application scenario. For example, the positions of the mixing inlet pipe 62 and the liquid outlet pipe 64 can be adjusted, and their number can also be adjusted. The separation pipe 65 can be set as a non-straight pipe, and its diameter can be greater than or equal to the diameters of the mixing inlet pipe 62 and the liquid outlet pipe 64, etc.

[0055] For example, in another alternative embodiment, the number of gas outlet pipes 63 is not fixed, and those skilled in the art can adjust their number based on design requirements. For example, with Figure 5 As shown in the example, the gas outlet pipe 63 can also be set to three, with the three gas outlet pipes 63 evenly distributed on the concentric circles of the outer circle of the top surface. Of course, the gas outlet pipe 63 can also be set to one, four or more.

[0056] For example, in another alternative embodiment, the arrangement of two micropores 66 located in the middle of the separation tube 65 along its length is not the only option; those skilled in the art can adjust it as needed. For instance, the number of micropores 66 can be adjusted based on the number of gas outlet tubes 63, and their placement can also be moved up or down.

[0057] For example, in another alternative embodiment, although the housing 61 is described as an inverted frustum shape, this is not the only embodiment. The shape of the housing 61 can also be cylindrical, rectangular, etc.

[0058] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.

[0059] Finally, combining Figure 1 The working process of the air conditioner described in this application is introduced.

[0060] See Figure 1When the air conditioner operates in cooling mode, the high-temperature, high-pressure gaseous refrigerant discharged from compressor 1 enters condenser 2 for heat exchange and liquefaction, becoming medium-temperature, high-pressure liquid refrigerant. Subsequently, the liquid refrigerant enters throttling element 3 for throttling, causing some of the liquid refrigerant to flash into a gaseous state, thus flowing out of the outlet of throttling element 3 as a low-temperature, low-pressure two-phase gas-liquid refrigerant. The low-temperature, low-pressure two-phase gas-liquid refrigerant enters separation pipe 65 from mixing inlet pipe 62. Within separation pipe 65, the liquid refrigerant, under the influence of centrifugal force, flows directly through liquid outlet pipe 64 to external heat exchange pipe 42, while the gaseous refrigerant flashes out again, passes through micropores 66, and flows out through gas outlet pipe 63 to internal heat exchange pipe 41. The refrigerant in the internal exhaust heat exchanger 41 and the external exhaust heat exchanger 42 simultaneously exchanges heat with the indoor air. The internal exhaust heat exchanger 41, containing gaseous refrigerant, has a higher evaporation temperature. Although lower than the dew point temperature, the temperature difference with the air dew point is small, resulting in lower dehumidification capacity and higher outlet air temperature. The external exhaust heat exchanger 42, containing liquid refrigerant, has a lower temperature, lower than the dew point temperature, and a larger temperature difference with the air dew point, resulting in stronger dehumidification capacity. It can lower the outlet air temperature while simultaneously dehumidifying. The outlet air from both heat exchangers mixes, achieving dual control of temperature and humidity. The gaseous refrigerant from the internal exhaust heat exchanger 41 and the external exhaust heat exchanger 42 merges at the manifold and returns to the compressor 1 from the compressor 1's suction port, thus completing one cycle.
