Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to a heat storage module, a heat storage arrangement structure, an air conditioner outdoor unit and an air conditioner. Background Art

[0002] When an air conditioner is in continuous heating mode in winter, the outdoor heat exchanger is prone to frost, resulting in reduced comfort. Sustainable heating air conditioners can address this problem. Compared to conventional units, sustainable heating air conditioners incorporate a thermal storage module. This energy storage device is used to defrost the evaporator during heating operation. This ensures that the unit can defrost the evaporator during normal heating operation without shutting down or switching to cooling mode, thus ensuring comfortable heating.

[0003] However, since the heat storage module itself is large in size, it will occupy too much space in the heat exchanger, resulting in a significant reduction in the area of the two devices of the air conditioner, so it is rarely used in practice. Utility Model Content

[0004] In view of this, the present invention provides a heat storage module, a heat storage arrangement structure, an air conditioner outdoor unit and an air conditioner to solve the problem that the heat storage module is large in size, which will occupy too much space of the heat exchanger and cause the area of the two devices of the air conditioner to be greatly reduced.

[0005] In a first aspect, the present invention provides a heat storage module, comprising:

[0006] The heat storage body includes a refrigerant pipeline; the heat storage body is entirely encapsulated to form a strip structure; the inlet pipe and the outlet pipe of the refrigerant pipeline extend from the end of the heat storage body.

[0007] Beneficial effects: Since the heat storage body is formed into a strip structure in the form of an integral package, it is small in size and can be easily integrated into the shell of the air-conditioning outdoor unit, such as above or below the outdoor heat exchanger of the air-conditioning outdoor unit. It will not occupy the layout space of the outdoor heat exchanger, and the area of the two devices of the air conditioner will not be reduced. It can be widely used in air conditioners. Furthermore, when the indoor unit continues to work normally in winter, the unit does not need to be shut down or switch the operating mode during the defrosting period of the outdoor unit. It only needs to provide heat for defrosting through the heat storage module, so as to realize continuous heating of the air conditioner without affecting the comfort of the user.

[0008] In an optional embodiment, the heat storage body is L-shaped or U-shaped.

[0009] Beneficial effects: The heat storage body is L-shaped, which is suitable for situations where the outdoor heat exchanger area is small, occupies less space and is convenient for layout; the heat storage body is U-shaped, occupies less space, and is also convenient for layout between the outdoor heat exchanger and the outdoor unit casing. Moreover, compared with the L-shaped heat storage body, it has a larger capacity and a wider range of applications.

[0010] In an optional embodiment, the heat storage body is connected in series or in parallel with a flat plate-shaped supplementary heat storage body through a pipeline.

[0011] Beneficial effect: A supplementary heat storage body is set on the heat storage body through a pipeline to expand the capacity. The supplementary heat storage body is set in a flat shape, which is also convenient for being set in the limited space of the outdoor unit casing, such as being laid flat between the heat storage body and the top cover of the outdoor unit.

[0012] In an optional embodiment, the refrigerant pipeline has an internal thread structure.

[0013] Beneficial effect: The internal thread structure can increase the internal surface area of the refrigerant pipeline and increase the heat exchange area with the refrigerant.

[0014] In a second aspect, the present invention further provides a heat storage arrangement structure, comprising:

[0015] an outdoor heat exchanger having a first connection structure;

[0016] The thermal storage module according to any one of the above items;

[0017] The second connecting structure is arranged at the end of the heat storage body and is connected with the first connecting structure.

[0018] Beneficial effects: The heat storage body and the outdoor heat exchanger are detachably connected through the first connecting structure and the second connecting structure. The heat storage body forms a strip structure in the form of an integral package. It is small in size and convenient to be integrated into the shell of the air-conditioning outdoor unit. It is arranged above or below the outdoor heat exchanger and does not occupy the layout space of the outdoor heat exchanger. The area of the two devices of the air conditioner will not be reduced. It can be widely used in air conditioners. During the defrosting period of the outdoor unit, the unit does not need to be shut down or switch the operating mode. It only needs to provide heat through the heat storage module to achieve continuous heating, which does not affect the user's comfort and improves user satisfaction.

[0019] In an optional embodiment, the heat storage arrangement further comprises:

[0020] The limiting assembly includes a plurality of fixing clips, and two ends of the fixing clips are respectively clamped on the outdoor heat exchanger and the heat storage body.

[0021] Beneficial effects: The heat storage arrangement structure includes a limiting component, which can limit and fix the heat storage body on the outdoor heat exchanger. The multiple fixing clips are set to prevent the heat storage body from moving, ensuring that the heat storage module will not be misplaced in the up and down and front and back directions, avoiding the outdoor heat exchanger from flipping over or damaging the heat exchange tubes, causing damage to the outdoor heat exchanger.

[0022] In an optional embodiment, the fixing clip is arranged near a bend of the heat storage body.

[0023] Beneficial effect: The bend of the heat storage body is prone to dislocation, so the fixing clip is set close to the bend to effectively prevent dislocation.

[0024] In an optional embodiment, the fixing clip includes:

[0025] Mounting piece;

[0026] Baffles, extending in pairs and arranged on one side of the mounting plate close to the heat storage body;

[0027] The positioning pieces are extended in pairs on a side of the mounting piece close to the outdoor heat exchanger.

[0028] Beneficial effect: When in use, first clamp the positioning piece on the outdoor heat exchanger, and then install the heat storage body between the baffles to complete the positioning of the heat storage body. The operation is convenient, saving time and effort; the installation piece is clamped between the heat storage body and the outdoor heat exchanger. Due to the positioning effect of the baffle, the heat storage body is not easy to shift, and will not collide with the outdoor heat exchanger to damage the outdoor heat exchanger.

[0029] In an optional embodiment, the heat storage module is arranged above the outdoor heat exchanger.

[0030] Beneficial Effects: There is a certain gap between the outdoor heat exchanger and the top cover of the outdoor unit. Placing the heat storage module within this limited space does not take up additional space for the outdoor heat exchanger, nor does it affect the heat exchange area of the heat exchanger. Furthermore, the heat storage module can be integrated into the outdoor unit housing. This approach, unlike related art designs where larger heat storage modules occupy a larger space, thus occupying space in the heat exchanger and affecting the heat exchange effect, or where the volume of the outdoor unit is significantly increased by adding space for the additional heat storage module without changing the volume of the heat exchanger, ensures that the heat exchanger remains unchanged without increasing the volume of the outdoor heat exchanger. This also enables continuous heating in winter without having to shut down the unit or switch operating modes for defrosting. Furthermore, locating the heat storage module above the outdoor heat exchanger facilitates installation.

[0031] In an optional embodiment, the inlet pipe and the outlet pipe are arranged at intervals, and the inlet pipe is arranged at the lower part of the heat storage module close to the outdoor heat exchanger, and the outlet pipe is arranged at the upper part of the heat storage module away from the outdoor heat exchanger.

[0032] Beneficial effect: The bottom-in and top-out method of refrigerant is mainly determined by the physical and chemical properties of the phase change material used as filler in the heat storage module. The filler will produce stratification under the action of gravity, while the bottom-in and top-out method utilizes thermal buoyancy to offset the influence of gravity.

[0033] In an optional embodiment, the heat storage module is arranged below the outdoor heat exchanger.

[0034] Beneficial effect: The heat storage module can also be arranged below the outdoor heat exchanger according to the space layout inside the outdoor unit casing, effectively utilizing the space of the outdoor unit casing, without occupying additional layout space of the heat exchanger, and is conveniently integrated into the outdoor unit casing.

[0035] In a third aspect, the present invention further provides an air-conditioning outdoor unit, comprising:

[0036] a housing, wherein a fan chamber and a compression chamber are formed in the housing;

[0037] The heat storage arrangement structure described in any one of the above items; the heat storage module is arranged in the fan chamber.

[0038] Beneficial effect: Due to the small-volume heat storage module of the present invention, the heat storage module can be conveniently arranged in the fan chamber without occupying the space of the outdoor heat exchanger and increasing the volume of the air conditioner outdoor unit.

[0039] In an optional embodiment, the outdoor heat exchanger is disposed in the fan chamber;

[0040] The shell includes a top cover and a bottom plate; the heat storage module is arranged on the upper side of the outdoor heat exchanger and below the top cover; or, the heat storage module is arranged on the lower side of the outdoor heat exchanger and above the bottom plate.

[0041] Beneficial effects: The heat storage module is arranged on the upper side of the outdoor heat exchanger, below the top cover; or, it is arranged on the lower side of the outdoor heat exchanger, above the chassis. With this arrangement, the small-volume heat storage module can be conveniently arranged in the shell of the outdoor heat exchanger, which is suitable for promotion and application. The air conditioner can perform defrosting operations without stopping or switching modes when continuously heating in winter, thereby improving user experience.

[0042] In a fourth aspect, the present invention further provides a heat storage module, comprising:

[0043] The heat storage body includes a refrigerant pipeline; the heat storage body is entirely encapsulated to form a columnar structure; the inlet pipe and the outlet pipe of the refrigerant pipeline extend from the end of the heat storage body.

[0044] Beneficial effects: The heat storage body is integrally packaged to form a columnar structure, which is small in size and can be easily integrated into the shell of the air-conditioning outdoor unit. For example, the compressor of the air-conditioning outdoor unit is located in the compression chamber, which will not occupy the layout space of the outdoor heat exchanger, and the area of the two devices of the air conditioner will not be reduced. It can be widely used in air conditioners. Furthermore, when the indoor unit continues to work normally in winter, the unit does not need to be shut down or switch the operating mode during the defrosting period of the outdoor unit. It only needs to provide heat for defrosting through the heat storage module, so as to realize continuous heating of the air conditioner without affecting the comfort of the user.

[0045] In an optional embodiment, the heat storage body is cylindrical.

[0046] Beneficial effects: The heat storage body is cylindrical, takes up little space, and can be easily arranged vertically in the outdoor unit housing; the cylindrical structure is also less likely to be scratched by other components, making installation more convenient.

[0047] In an optional embodiment, the refrigerant pipeline has an internal thread structure.

[0048] Beneficial effect: The internal thread structure can increase the internal surface area of the refrigerant pipeline and increase the heat exchange area with the refrigerant.

[0049] In a fifth aspect, the present invention further provides an air-conditioning outdoor unit, comprising:

[0050] a housing, wherein a fan chamber and a compression chamber are formed in the housing;

[0051] a compressor, disposed in the compression chamber;

[0052] The heat storage module described in any one of the above items is arranged side by side with the compressor in the compression chamber.

[0053] Beneficial effects: Since the small-volume heat storage module of the utility model is included, it is convenient to set the heat storage module in the compression chamber. Since it does not occupy the space of the outdoor heat exchanger, it does not affect the heat exchange efficiency. Since it does not increase the volume of the air-conditioning outdoor unit, it is convenient to promote and apply.

[0054] In a sixth aspect, the present invention further provides an air conditioner, comprising the air conditioner outdoor unit described in any one of the above items.

[0055] Beneficial Effects: Due to the inclusion of the compact heat storage module of the present invention, the heat storage module can be conveniently integrated into the outdoor unit housing without occupying the layout space of the outdoor heat exchanger. This does not affect the heat exchange efficiency and does not increase the size of the air conditioner outdoor unit, facilitating widespread application. During winter, when the indoor unit of the air conditioner continues to operate normally, the outdoor unit does not need to shut down or switch operating modes during defrosting. Simply using the heat provided by the heat storage module for defrosting, the air conditioner can continue heating without affecting user comfort and improving user satisfaction.

In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0094] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0095] The following combination Figures 1 to 13 , describing the embodiments of the present utility model.

[0096] According to an embodiment of the present invention, on the one hand, a thermal storage module is provided, comprising:

[0097] The heat storage body 100 includes a refrigerant pipeline. The heat storage body 100 is encapsulated as a whole to form a strip structure. The inlet pipe 102 and the outlet pipe 101 of the refrigerant pipeline extend from the end of the heat storage body 100.

[0098] Since the heat storage body 100 is formed into a strip structure in the form of an integral package, it is small in size and can be easily integrated into the housing of the air-conditioning outdoor unit, for example, above or below the outdoor heat exchanger 200 of the air-conditioning outdoor unit, without occupying the layout space of the outdoor heat exchanger 200, and the area of the two devices of the air conditioner will not be reduced. It can be widely used in air conditioners. Furthermore, when the indoor unit continues to work normally in winter, the unit does not need to be shut down or switch the operating mode during the defrosting period of the outdoor unit. It only needs to provide heat for defrosting through the heat storage module, thereby realizing continuous heating of the air conditioner without affecting the comfort of the user.

[0099] In some embodiments, as Figure 3 As shown, the heat storage body 100 is L-shaped.

[0100] The heat storage body 100 is L-shaped, which is suitable for situations where the outdoor heat exchanger 200 has a smaller area, occupies less space, and is convenient for layout.

[0101] In some embodiments, as Figure 2 As shown, the heat storage body 100 is U-shaped.

[0102] The heat storage body 100 is U-shaped, occupies little space, and is conveniently arranged between the outdoor heat exchanger 200 and the outdoor unit casing. Moreover, compared with the L-shaped heat storage body 100, it has a larger capacity and a wider range of applications.

[0103] In some embodiments, the thermal storage body 100 is connected in series or in parallel with a flat-plate supplementary thermal storage body 400 via a pipeline.

[0104] A supplementary heat storage body 400 is provided on the heat storage body 100 through a pipeline to expand the capacity. The supplementary heat storage body 400 is provided in a flat plate shape, which is also convenient for being provided in the limited space of the outdoor unit casing, such as being laid flat between the heat storage body 100 and the top cover of the outdoor unit.

[0105] like Figure 9 As shown, a flat plate-shaped supplementary heat storage body 400 is additionally provided on the L-shaped heat storage body 100 .

[0106] In some embodiments, the refrigerant pipe has an internal thread structure.

[0107] The internal thread structure can increase the inner surface area of the refrigerant pipeline and increase the heat exchange area with the refrigerant.

[0108] like Figure 5 As shown, the heat storage body 100 includes an inner container, a heat insulation layer 106 and a peripheral structure.

[0109] According to an embodiment of the present invention, on the other hand, a heat storage arrangement structure is provided, comprising:

[0110] The outdoor heat exchanger 200 has a first connection structure;

[0111] The heat storage module, the end of the heat storage body 100 is provided with a second connection structure, and the second connection structure is connected with the first connection structure.

[0112] The heat storage body 100 and the outdoor heat exchanger 200 are detachably connected through the first connection structure and the second connection structure. The heat storage body 100 is formed into a strip structure in the form of an integral package. It is small in size and can be easily integrated into the shell of the air-conditioning outdoor unit. It is arranged above or below the outdoor heat exchanger 200 and does not occupy the arrangement space of the outdoor heat exchanger 200. The area of the two devices of the air conditioner will not be reduced. It can be widely used in air conditioners. During the defrosting period of the outdoor unit, the unit does not need to be shut down or switch the operating mode. It only needs to provide heat through the heat storage module to achieve continuous heating, which does not affect the user's comfort and improves user satisfaction.

[0113] In some embodiments, the thermal storage arrangement further comprises:

[0114] The limiting assembly includes a plurality of fixing clips 300 , and two ends of the fixing clips 300 are respectively clamped on the outdoor heat exchanger 200 and the heat storage body 100 .

[0115] The heat storage arrangement structure includes a limiting assembly, which can limit and fix the heat storage body 100 on the outdoor heat exchanger 200. The multiple fixing clips 300 are set to prevent the heat storage body 100 from moving, ensuring that the heat storage module will not be misplaced in the vertical and front-to-back directions, avoiding the outdoor heat exchanger 200 from falling over or damaging the heat exchange tubes, causing damage to the outdoor heat exchanger 200.

[0116] In some embodiments, the fixing clip 300 is disposed near the bend 103 of the thermal storage body 100 .

[0117] The bend 103 of the heat storage body 100 is prone to dislocation, so the fixing clip 300 is arranged near the bend to effectively prevent dislocation.

[0118] In some embodiments, the retaining clip 300 includes:

[0119] Mounting piece 301;

[0120] The blocking pieces 302 are extended in pairs and arranged on one side of the mounting piece 301 close to the heat storage body 100;

[0121] The positioning pieces 303 are extended in pairs on one side of the mounting piece 301 close to the outdoor heat exchanger 200 .

[0122] During use, the positioning piece 303 is first snapped onto the outdoor heat exchanger 200, and then the heat storage body 100 is snapped into place between the blocking pieces 302 to complete the positioning of the heat storage body 100. The operation is convenient and saves time and effort. The mounting piece 301 is clamped between the heat storage body 100 and the outdoor heat exchanger 200. Due to the positioning effect of the blocking piece 302, the heat storage body 100 is not easily displaced and will not collide with the outdoor heat exchanger 200 to damage the outdoor heat exchanger 200.

[0123] Specifically, if Figure 4 As shown, the fixing clamp 300 includes two pairs of baffles 302 and a pair of positioning pieces 303. The baffles 302 are positioned at the four corners of the mounting piece 301, and the positioning pieces 303 are positioned between the two baffles 302 on the corresponding side. The baffles 302 and positioning pieces 303 extend in opposite directions. Each baffle 302 has a first folded edge 3021 formed at its end, and each positioning piece 303 has a second folded edge 3031 formed at its end. This allows the entrance to the confined space formed between the baffles 302 to open outward, and the entrance to the mounting space formed between the positioning pieces 303 to open outward as well, creating a guide that facilitates assembly with the thermal storage module and outdoor heat exchanger 200.

[0124] In some embodiments, the heat storage module is disposed above the outdoor heat exchanger 200 .

[0125] There is a certain gap between the outdoor heat exchanger 200 and the top cover of the outdoor unit. Placing the heat storage module within this limited space does not take up additional space on the outdoor heat exchanger 200, nor does it affect the heat exchange area of the heat exchanger. Furthermore, the heat storage module can be integrated into the outdoor unit housing. This solution, unlike related art designs where a larger heat storage module occupies a larger space within the heat exchanger, thus affecting heat exchange efficiency, or where the additional space for the heat storage module remains unchanged, significantly increasing the size of the outdoor unit. This solution avoids excessive space usage in the heat exchanger, significantly reducing the area of both units, and also does not increase the size of the outdoor heat exchanger 200. Furthermore, it enables continuous heating in winter without having to shut down the unit or switch operating modes for defrosting. Furthermore, locating the heat storage module above the outdoor heat exchanger 200 simplifies installation and facilitates maintenance and replacement.

[0126] In some embodiments, the inlet pipe 102 and the outlet pipe 101 are arranged at intervals, and the inlet pipe 102 is arranged at the lower part of the heat storage module close to the outdoor heat exchanger 200, and the outlet pipe 101 is arranged at the upper part of the heat storage module away from the outdoor heat exchanger 200.

[0127] The bottom-in and top-out method of the refrigerant pipeline is mainly determined by the physical and chemical properties of the phase change material 104 used as the filler in the heat storage module. The filler will produce stratification under the action of gravity, and the bottom-in and top-out method utilizes thermal buoyancy to offset the influence of gravity.

[0128] In some embodiments, the heat storage module is disposed below the outdoor heat exchanger 200 .

[0129] The heat storage module can also be arranged below the outdoor heat exchanger 200 according to the space layout in the outdoor unit casing, effectively utilizing the space in the outdoor unit casing, without occupying additional layout space of the heat exchanger, and conveniently integrated into the outdoor unit casing.

[0130] According to an embodiment of the present invention, on the other hand, an air conditioner outdoor unit is provided, comprising:

[0131] a housing, wherein a fan chamber and a compression chamber are formed in the housing;

[0132] Heat storage arrangement structure, the heat storage module is arranged in the fan chamber.

[0133] Due to the small-volume heat storage module of the present invention, the heat storage module can be conveniently arranged in the fan chamber without occupying the space of the outdoor heat exchanger 200 and increasing the volume of the air conditioner outdoor unit.

[0134] In some embodiments, the outdoor heat exchanger 200 is disposed within the fan chamber;

[0135] The shell includes a top cover and a bottom plate; the heat storage module is arranged on the upper side of the outdoor heat exchanger 200 and below the top cover; or, the heat storage module is arranged on the lower side of the outdoor heat exchanger 200 and above the bottom plate.

[0136] The heat storage module is arranged on the upper side of the outdoor heat exchanger 200, below the top cover; or, it is arranged on the lower side of the outdoor heat exchanger 200, above the chassis. With this arrangement, the small-volume heat storage module can be conveniently arranged in the shell of the outdoor heat exchanger 200, which is suitable for promotion and application. The air conditioner can perform defrosting operations without stopping or switching modes during continuous heating in winter, thereby improving user experience.

[0137] The air conditioner outdoor unit includes a compressor 600, a piping system, an electrical box, an outdoor heat exchanger 200, and a fan system. The left side of the unit, separated by a central partition 500, is the fan side 10, which forms a fan chamber. The fan chamber typically houses the outdoor heat exchanger 200 and the fan system. The right side of the unit is the compression side 20, which forms a compression chamber. The compression chamber houses the compressor 600, the electrical box, and the piping system. Figure 1 and Figure 11 As shown, the heat storage module is packaged into an integral module, which is connected to the side plates of the outdoor heat exchanger 200 by screws through the sheet metal at both ends, and the middle section is set above the heat exchanger and below the top cover using multiple fixing clips 300.

[0138] Of course, the heat storage module can also be placed below the outdoor heat exchanger 200 and above the chassis. In this case, the heat storage module needs to be completely sealed to ensure that condensed water does not enter the heat storage module when the outdoor heat exchanger 200 defrosts.

[0139] The heat storage module can be processed into a U-shape or an L-shape according to the shape of the outdoor heat exchanger 200, with an inlet pipe 102 and an outlet pipe 101 left at both ends. Figure 2 and Figure 3 As shown in the figure, the U-shape is preferred, as the thermal storage module volume is larger than other shapes.

[0140] The thermal storage module packaging structure includes an inner liner, an insulation layer 106, and an outer layer. The inner liner includes a phase change material 104 and a refrigerant pipe for refrigerant, and the refrigerant pipe forms a network of pipes. The outer layer includes a bottom shell 109 and a cover plate 108. A gap 107 is reserved between the cover plate 108 on the inner liner and the phase change material 104 to meet the expansion requirements of the phase change material 104. Figure 5 The inner wall of the refrigerant pipeline is rough, and an uneven inner wall is adopted, preferably an internal thread structure, which can increase the heat exchange area with the refrigerant.

[0141] The outer layer of the heat storage module is sealed by the bottom shell 109 and the cover plate 108, and the inlet pipe 102 and outlet pipe 101 of the refrigerant are left at the right end. The position where the inlet pipe 102 and the outlet pipe 101 contact the bottom shell 109 is provided with a rubber sealing rubber ring 110, such as Figure 6 The heat storage module is equipped with a copper-aluminum heat exchange assembly 105. The copper tubes constituting the heat exchange assembly 105 are arranged in layers. The inlet tube 102 needs to be arranged at the bottom of the heat storage module, and the outlet tube 101 needs to be arranged at the top of the heat storage module. This arrangement helps the upward thermal buoyancy of the phase change material 104 overcome the downward gravity, avoiding the delamination of the phase change material 104 and affecting the heat storage effect. Figure 7 .

[0142] The fixing clip 300 can be made of sheet metal or other alloy materials, preferably hot-dip galvanized and spray-coated. The fixing clip 300 is preferably positioned near the curved arc section of the thermal storage body 100 to ensure that the thermal storage module and the outdoor heat exchanger 200 are aligned vertically and longitudinally, preventing the outdoor heat exchanger 200 from tilting or damaging the copper pipe, thereby damaging the heat exchanger.

[0143] For a small cooling unit with a large shell size, a large heat exchanger area is not required. In this case, the heat storage module can be preferably placed in an L shape above the heat exchanger, such as Figure 8 shown.

[0144] For units with larger heat exchanger areas, more heat is required for defrosting during continuous heating, thus requiring a larger heat storage module. In this case, the heat storage module is preferably designed with a large size and placed above the heat exchanger and below the top cover, such as Figure 9 shown.

[0145] The heat storage module is arranged in the fan chamber and is welded to the copper tube in the unit compression chamber through the inlet pipe 102 and the outlet pipe 101. Figure 10 shown.

[0146] According to an embodiment of the present invention, in another aspect, a heat storage module is provided, comprising:

[0147] The heat storage body 100 includes a refrigerant pipeline. The heat storage body 100 is encapsulated as a whole to form a columnar structure. The inlet pipe 102 and the outlet pipe 101 of the refrigerant pipeline extend from the end of the heat storage body 100.

[0148] The heat storage body 100 is encapsulated as a whole to form a columnar structure, which is small in size and can be easily integrated into the shell of the air-conditioning outdoor unit. For example, the compressor 600 of the air-conditioning outdoor unit is located in the compression chamber, and will not occupy the layout space of the outdoor heat exchanger 200. The area of the two devices of the air conditioner will not be reduced. It can be widely used in air conditioners. Furthermore, when the indoor unit continues to work normally in winter, the unit does not need to be shut down or switch the operating mode during the defrosting period of the outdoor unit. It only needs to provide heat for defrosting through the heat storage module, so as to achieve continuous heating of the air conditioner without affecting the comfort of the user.

[0149] In some embodiments, as Figure 12 and Figure 13 As shown, the heat storage body 100 is cylindrical.

[0150] The heat storage body 100 is cylindrical in shape, occupies little space, and can be conveniently arranged vertically in the outdoor unit housing; moreover, the cylindrical structure is not easily scratched by other components, making installation more convenient.

[0151] Specifically, the refrigerant pipeline is provided with an internal thread structure.

[0152] The internal thread structure can increase the inner surface area of the refrigerant pipeline and increase the heat exchange area with the refrigerant.

[0153] According to an embodiment of the present invention, in another aspect, an air conditioner outdoor unit is provided, comprising:

[0154] a housing, wherein a fan chamber and a compression chamber are formed in the housing;

[0155] The compressor 600 is disposed in the compression chamber;

[0156] The heat storage module and the compressor 600 are arranged side by side in the compression chamber.

[0157] Since the utility model includes a small-volume heat storage module, it is convenient to set the heat storage module in the compression chamber. Since it does not occupy the space of the outdoor heat exchanger 200, it does not affect the heat exchange efficiency. Since it does not increase the volume of the air conditioner outdoor unit, it is convenient to promote and apply.

[0158] According to an embodiment of the present invention, in another aspect, an air conditioner is provided, including an air conditioner indoor unit and an air conditioner outdoor unit.

[0159] Because the air conditioner outdoor unit includes the compact heat storage module of the present invention, it can be conveniently integrated into the outdoor unit housing without occupying the space required for the outdoor heat exchanger 200. This allows for uncompromising heat exchange efficiency and does not increase the size of the air conditioner outdoor unit, facilitating widespread application. During winter, when the indoor unit of the air conditioner continues to operate normally, the outdoor unit does not need to shut down or switch operating modes during defrosting. Instead, the heat storage module provides heat for defrosting, ensuring continuous heating without compromising user comfort and improving user satisfaction.

[0160] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
