[0001] The present application relates to the technical field of equipment operation status control, and in particular to a partition assembly, a shell assembly, an outdoor unit and an air-conditioning system. Background Art

[0002] In various mechanical devices or electrical equipment, partitions are often used to separate two or more component installation chambers (or installation spaces) inside the housing of the device to achieve partitioned installation of multiple components to avoid mutual interference between components in different component installation chambers during operation.

[0003] Taking air-conditioning equipment as an example, in the existing technology, partitions are often set in the outdoor unit casing to form a compressor cavity and a fan cavity inside the outdoor unit. The setting of the partition can prevent air from flowing between the compressor cavity and the fan cavity, affecting the air inlet and outlet effects of the outdoor unit.

[0004] However, when the compressor is working, the strong vibration frequency of the compressor will often cause the partition to resonate, resulting in loud noise in the entire shell and equipment. In severe cases, it may even affect the user's normal rest and physical and mental health, resulting in a poor user experience. Utility Model Content

[0044] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0046] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0047] In order to solve the technical problem in the prior art that when a partition is set inside the shell of a device, noise is easily generated due to the resonance of the partition, the present application provides a partition assembly 2, a shell assembly, an outdoor unit and an air-conditioning system. The partition assembly 2 includes a liquid inlet pipe 21, a liquid storage chamber 22 and a liquid outlet pipe 23 connected in sequence. The liquid mass in the liquid storage chamber 22 can be adjusted by the liquid inlet pipe 21 and / or the liquid outlet pipe 23, thereby achieving the mass adjustment of the partition assembly 2, and then changing the natural frequency of the partition assembly 2 to avoid resonance of the partition assembly 2, which can reduce or avoid the generation of noise.

[0048] See also Figures 1 to 9 In a first aspect, an embodiment of the present application provides a partition assembly 2, which includes a liquid inlet pipe 21, a liquid storage chamber 22 and a liquid outlet pipe 23 connected in sequence. The amount of liquid stored in the liquid storage chamber 22 is adjusted by the liquid inlet pipe 21 and / or the liquid outlet pipe 23 to achieve mass adjustment of the partition assembly 2, thereby changing the natural frequency of the partition assembly 2 and avoiding resonance and noise.

[0049] Specifically, when the mass of the partition assembly 2 needs to be increased, the liquid outlet pipe 23 can be closed, and a predetermined mass of liquid can be introduced into the liquid storage chamber 22 through the liquid inlet pipe 21 to increase the mass of the partition assembly 2. When the mass of the partition assembly 2 needs to be reduced, the liquid inlet pipe 21 can be closed, and the liquid in the liquid storage chamber 22 can be discharged through the liquid outlet pipe 23 to reduce the mass of the partition assembly 2. As the mass of the partition assembly 2 changes, its corresponding natural frequency also changes, thereby preventing resonance and noise.

[0050] In some embodiments of the present application, a first valve component is provided on the liquid inlet pipe 21, and a second valve component 28 is provided on the liquid outlet pipe 23, which can be used to realize on-off control of the liquid inlet pipe 21 and the liquid outlet pipe 23, so as to facilitate the flow of liquid into or out of the liquid storage chamber 22, thereby realizing the mass and natural frequency adjustment of the partition assembly 2.

[0051] In some embodiments of this application, please refer to Figure 1 、 Figure 2 and Figure 3 The partition assembly 2 includes a first partition 24 and a second partition 25. The first partition 24 and the second partition 25 are arranged opposite each other, and a liquid storage chamber 22 is formed between the first partition 24 and the second partition 25. The first partition 24 and the second partition 25 can seal both sides of the liquid storage chamber 22. A liquid outlet pipe 23 is provided at the bottom of the first partition 24 or the bottom of the second partition 25, which facilitates the discharge of liquid from the liquid storage chamber 22 and reduces liquid residue within the liquid storage chamber 22, thereby expanding the mass adjustment range of the partition assembly 2.

[0052] See also Figures 1 to 9 The second aspect of the embodiment of the present application provides a housing assembly, including a housing component 1 and a partition component 2, such as Figure 1 As shown, the housing assembly 1 has a cavity inside, which can be used to install various components and protect the various components installed therein. The partition assembly 2 is disposed inside the housing assembly 1, dividing the cavity into two or more component installation chambers, which is used to realize the partitioned installation of multiple components and prevent various components from adversely affecting other components during operation.

[0053] It should be noted that the partition assembly 2 is fixedly disposed inside the housing assembly 1 and can be fixedly or detachably connected to the inner wall of the housing assembly 1. The shape of the partition assembly 2 can be designed according to the layout requirements of the component installation chamber and is not limited here.

[0054] It should be noted that the liquid storage chamber 22 can be formed by connecting the plates of the partition assembly 2 itself, such as Figure 3 As shown, the first partition plate 24, the second partition plate 25, the top plate 27, the bottom plate 26 and the side plate (not shown) are connected to form a closed liquid storage chamber 22. The liquid storage chamber 22 can also be formed by sealingly connecting the first partition plate 24, the second partition plate 25, the side plate and the inner wall of the shell, as shown in FIG. Figure 1 As shown, the purpose of this application can be achieved.

[0055] In some embodiments of this application, please refer to Figure 1 and Figure 4The partition assembly 2 and / or the outer shell assembly 1 are provided with a vibration detection member 3, which can be used to directly or indirectly detect the resonance of the partition assembly 2, so as to facilitate timely quality adjustment of the partition assembly 2. When the vibration detection member 3 is provided on the partition assembly 2, the resonance of the partition assembly 2 can be directly detected; when the vibration detection member 3 is provided on the outer shell assembly 1, since the partition assembly 2 is connected to the outer shell assembly 1, its vibration will be transmitted to the outer shell assembly 1, and the resonance of the partition assembly 2 can be indirectly detected through the vibration detection of the outer shell assembly 1, and the purpose of resonance detection can be achieved in both cases.

[0056] In some embodiments of the present application, the vibration detection member 3 may be a component such as a strain gauge, a vibration sensor, or a noise sensor. Since the vibration sensor may be interfered with by environmental factors such as noise, instability of the vibration source, etc. when detecting resonance phenomena, these interference factors may increase the error of the detection result or make it impossible to accurately judge the resonance phenomenon. The noise sensor is also easily interfered with by the operating noise of other components or external noise, resulting in a certain error in the detection situation. Therefore, in some preferred embodiments of the present application, the vibration detection member 3 includes a strain gauge attached to the partition assembly 2 or the housing assembly 1. The strain gauge has a strong anti-interference ability. The vibration of the partition assembly 2 is monitored in real time according to the change in the strain value detected by the strain gauge to confirm whether the partition assembly 2 resonates.

[0057] As a specific embodiment of the present application, the strain gauge is directly attached to the outer surface of the diaphragm assembly 2, such as Figure 1 and Figure 4 As shown, the vibration and stress state of the structure are reflected by the change in the strain value on the outer surface of the partition assembly 2. This direct measurement method enables the strain gauge to accurately capture the tiny changes in the partition assembly 2 during resonance, providing reliable data support for resonance analysis.

[0058] It should be noted that the housing assembly of the present application can be applied to any mechanical device or electrical equipment, forming a plurality of mutually separated component installation chambers inside the housing component 1 while avoiding resonance and noise generation by the partition component 2.

[0059] See also Figures 1 to 9 In a third aspect of an embodiment of the present application, an outdoor unit is provided, comprising the shell assembly of the above embodiment, wherein the component installation chamber comprises a first chamber 11 and a second chamber 12, wherein the first chamber 11 is a compressor chamber, and the second chamber 12 is a fan chamber. The compressor chamber and the fan chamber are separated by a partition assembly 2, thereby avoiding cross-flow of airflow inside the outdoor unit, which is beneficial to ensuring the air inlet and outlet effects of the outdoor unit, and thereby ensuring the heat exchange efficiency of the outdoor unit.

[0060] In some embodiments of this application, please refer to Figure 4The partition assembly 2 extends vertically, with the first chamber 11 and the second chamber 12 located on either side of the partition assembly 2, allowing the compressor chamber and the fan chamber to be arranged horizontally in sequence. Compressor 4 is located at the bottom of the first chamber 11, which reduces the installation height and improves the installation stability of compressor 4, thereby reducing vibration of the entire machine and reducing the possibility of resonance of the partition assembly 2.

[0061] Since the outdoor unit is placed outdoors, when the external ambient temperature is low, even reaching -25°C in extremely cold regions, the user will adjust the air conditioning system to heating mode. A heat exchange fin assembly 8 is provided in the fan chamber, and a refrigerant pipeline is provided in the heat exchange fin assembly 8. Since the refrigerant temperature in the heat exchange fins is much lower than the ambient temperature, moisture in the air will condense when it contacts the fins. Since the ambient temperature in the air is below zero, the condensation will quickly turn into frost and cover the fins. At this time, the air conditioning system will periodically reverse the direction of the four-way valve to heat the fins, melting the frost on the fins. The melted water will drip into the water collection pan 6 at the bottom of the fan chamber. Although drainage holes are provided on the water collecting pan 6, when the outdoor temperature is too low, the water in the water collecting pan 6 will quickly freeze into ice, thereby blocking the drainage holes in the water collecting pan 6, causing ice to continuously accumulate on the water collecting pan 6. When the ice accumulates to the height of the bottom of the fins, the continuous expansion of the ice will continuously squeeze and deform the fins, causing the refrigerant pipeline inside the fins to rupture, refrigerant leakage and damage to the unit.

[0062] To solve the above problems, in some embodiments of this application, please refer to Figure 4 The first chamber 11 is provided with a heat absorbing component 5, which is sleeved on the outer periphery of the compressor 4. The interior of the heat absorbing component 5 is provided with a liquid heat conducting medium, which can absorb the heat generated by the compressor 4 and realize the recovery of the waste heat of the compressor 4. The outlet of the heat absorbing component 5 is connected to the liquid inlet pipe 21, and the liquid heat conducting medium after absorbing the heat can be input into the liquid storage chamber 22. The second chamber 12 is provided with a water collecting bottom plate 6, which is provided with a drainage hole; the liquid outlet pipe 23 is connected to the water collecting bottom plate 6. When ice forms inside the water collecting bottom plate 6, the liquid heat conducting medium in the liquid storage chamber 22 can be discharged into the water collecting bottom plate 6. The liquid heat conducting medium that has absorbed the waste heat of the compressor 4 melts the solidified ice in the water collecting bottom plate 6, and realizes the dredging of the drainage hole, thereby preventing the ice in the water collecting bottom plate 6 from further expanding and squeezing the heat exchange fin assembly 8.

[0063] It should be noted that the present application connects the heat absorption component 5, the liquid storage chamber 22 and the water collecting chassis 6 in sequence, and can adjust the mass of the partition component 2 by inputting liquid heat conducting medium into the liquid storage chamber 22, and can melt the solidified ice in the water collecting chassis 6 by discharging liquid heat conducting medium that has absorbed the waste heat of the compressor 4 into the water collecting chassis 6, thereby realizing the noise reduction and ice melting functions of the outdoor unit simultaneously or separately.

[0064] Specifically, when the inlet pipe 21 is open and the outlet pipe 23 is closed, the noise reduction function can be achieved independently. When both the inlet pipe 21 and the outlet pipe 23 are open and their flow rates are the same, the mass of the partition assembly 2 does not change, and the ice-melting function can be achieved independently. Opening the inlet pipe 21 for a period of time and then opening the outlet pipe 23 can achieve both noise reduction and ice-melting functions in sequence. When both the inlet pipe 21 and the outlet pipe 23 are opened simultaneously, but the flow rate of the inlet pipe 21 is greater than that of the outlet pipe 23, the bulkhead assembly 2 can simultaneously increase in weight and melt ice, achieving both noise reduction and ice-melting functions.

[0065] In some embodiments of the present application, the liquid heat exchange medium is preferably water. When the liquid heat exchange medium and the melted water in the water collecting bottom plate 6 are mixed, they are discharged from the outdoor unit through the drainage hole together, which can avoid adverse effects on the environment.

[0066] In some embodiments of the present application, the liquid inlet pipe 21 and the liquid outlet pipe 23 are respectively provided on both sides of the partition assembly 2, and can be connected to the heat absorption assembly 5 in the first chamber 11 and the water collecting bottom plate 6 in the second chamber 12. Specifically, the liquid inlet pipe 21 is provided on the first partition 24, and the liquid outlet pipe 23 is provided at the bottom of the second partition 25. Figure 4 shown.

[0067] In some embodiments of this application, please refer to Figure 5 、 Figure 6 and Figure 7 The heat absorption assembly 5 includes a flexible bag 51 that surrounds the outer periphery of the compressor 4. The flexible bag 51 deforms to conform to the outer surface of the compressor 4, increasing the heat exchange area between the heat absorption assembly 5 and the compressor 4 and improving heat exchange efficiency. The flexible bag 51 has a chamber inside for holding a liquid heat-conducting medium.

[0068] In some embodiments of the present application, the flexible bag body 51 is a one-piece structure, and the flexible bag body 51 is clamped on the outside of the compressor 4 through the connecting portion 52, such as Figure 6 As shown, the flexible bag body 51 can be fixedly arranged to prevent the flexible bag body 51 from being shaken off due to the vibration of the compressor 4.

[0069] In some embodiments of the present application, the heat absorption component 5 also includes a water inlet pipe 53 and a water outlet pipe 54 connected to the flexible bag body 51, wherein the water inlet pipe 53 is connected to the water source, and the water outlet pipe 54 is connected to the liquid inlet pipe 21 of the partition assembly 2, for continuously providing high-temperature liquid after heat absorption to the heat absorption component 5, the partition assembly 2 and the water collection bottom plate 6.

[0070] In some embodiments of the present application, the heat absorption component 5 is made of a heat-conducting material with a high melting temperature, such as silicone, which has good thermal conductivity and can prevent the flexible bag 51 from being damaged due to long-term exposure to the surface temperature of the compressor 4.

[0071] In other embodiments of the present application, heat absorption assembly 5 includes a coil wrapped around the periphery of compressor 4. Liquid heat exchange medium flows within the coil to absorb waste heat from compressor 4. The outlet of the coil is connected to a liquid inlet pipe 21, which sequentially delivers the high-temperature liquid after heat exchange to baffle assembly 2 and water collection pan 6.

[0072] In some embodiments of this application, please refer to Figure 4 A pump assembly 7 is also provided in the first chamber 11. This pump assembly 7 is connected to the inlet of the heat absorbing assembly 5 and is used to supply liquid heat exchange medium to the heat absorbing assembly 5. It also provides power for the liquid heat exchange medium to circulate between the heat absorbing assembly 5, the baffle assembly 2, and the water collection pan 6. The pump assembly 7 includes a third valve 72 disposed at the inlet of the heat absorbing assembly 5 to control liquid delivery.

[0073] It should be noted that when a third valve component 72 is provided at the inlet of the heat absorption component 5, the liquid inlet pipe 21 of the partition component 2 does not need to be provided with a first valve component, and the liquid inlet control of the heat absorption component 5 and the partition component 2 can be achieved through the third valve component 72.

[0074] In some embodiments of the present application, the pump assembly 7 also includes a water pump 71, an input pipeline 73 and an output pipeline 74, wherein the input pipeline 73 is used to connect the water pump 71 and the water source, and the output pipeline 74 is connected to the third valve component 72. When there is no need to input liquid heat exchange medium into the heat absorption component 5, the liquid heat exchange medium can be input into other areas or components requiring liquid water through the third valve component 72. According to the number of output pipelines 74, the third valve component 72 can be set to a two-way valve, a three-way valve, etc. At this time, the third valve component 72 is preferably a solenoid valve to facilitate the connection control of the third valve component 72.

[0075] In some embodiments of this application, please refer to Figure 4The water collecting pan 6 is located below the heat exchange fin assembly 8 and is used to collect water dripping from the heat exchange fin assembly 8. A liquid level detection component 9 is provided in the water collecting pan 6 to detect the liquid level in the water collecting pan 6. When the drainage hole in the water collecting pan 6 is blocked by solidified ice, the water level inside the water collecting pan 6 will rise rapidly, so that it can be confirmed whether there is ice formation in the water collecting pan 6 by the change in water level.

[0076] In some embodiments of this application, please refer to Figure 8 The outdoor unit also includes a control unit, and the vibration detection element 3, the liquid level detection element 9, the water pump 71 and multiple valve components are all connected to the control unit signal. Figure 8 The arrow in the middle indicates the direction of signal flow. The control unit uses the monitoring signals from the vibration detector 3 and the liquid level detector 9 to determine whether the outdoor unit is in a resonant or frozen state. It then controls the water pump 71 and valves to automatically achieve the outdoor unit's noise reduction and ice-melting functions.

[0077] See also Figures 1 to 9 A fourth aspect of the present application provides an air conditioning system, including the outdoor unit of the aforementioned embodiment. During operation, the air conditioning system can prevent resonance in the outdoor unit by changing the mass of the partition assembly, recover waste heat from the compressor 4 through the heat absorption assembly 5, and utilize the waste heat from the compressor 4 to achieve noise reduction and ice-melting functions in the outdoor unit.

[0078] See also Figures 1 to 9 , an embodiment of the present application provides a control method, which is applied to the outdoor unit in the above embodiment, comprising the following steps:

[0079] After the outdoor unit is powered on, the vibration state of the housing assembly is monitored to obtain the current vibration parameter L1; the freezing state of the water collecting bottom plate 6 is monitored to obtain the current freezing parameter X1.

[0080] In some embodiments of the present application, the current vibration parameter is one or more of the noise parameter, strain parameter or amplitude parameter of the shell assembly; since the present application preferably sets the strain gauge as the vibration detection component 3 on the partition assembly 2, the current vibration parameter L1 of the present application is the measured value of the strain gauge.

[0081] In some embodiments of the present application, the current freezing parameter X1 is a liquid level parameter of the water collecting pan 6 or a flow parameter of the drain hole. Since the liquid level detection element 9 is preferably provided in the water collecting pan 6 in the present application, the current freezing parameter X1 is the liquid level height of the water collecting pan 6.

[0082] The current vibration parameters are compared with the preset vibration thresholds, and the current freezing parameters are compared with the preset freezing thresholds. Based on the comparison results, it is determined whether the outdoor unit is in a resonance state, freezing state, or resonance freezing state, and the noise reduction mode, ice-melting mode, or ice-melting noise reduction mode is triggered.

[0083] In some embodiments of this application, please refer to Figure 8 and Figure 9 , the preset vibration threshold is L, the preset freezing threshold is X, if the current vibration parameter L1> the preset vibration threshold L, and the current freezing parameter X1≤ the preset freezing threshold X, it means that the strain of the partition assembly 2 exceeds the standard due to resonance, the outdoor unit is in a resonant state, and the noise reduction mode needs to be triggered by the control unit.

[0084] When noise reduction mode is activated, the second valve 28 on the liquid outlet pipe 23 is closed, the third valve 72 is opened (if a first valve is provided, the first valve is also opened simultaneously), the liquid inlet pipe 21 is connected to the heat absorption assembly 5 and the pump element, and liquid water is delivered to the liquid storage chamber 22, increasing the mass of the partition assembly 2 until the current vibration parameter L1 is less than or equal to the preset vibration threshold L, the resonance phenomenon disappears, and the noise is reduced. The third valve 72 is closed (if a first valve is provided, the first valve is also closed simultaneously), and the liquid inlet pipe 21 is closed.

[0085] If the current vibration parameter L1 ≤ the preset vibration threshold L, and the current freezing parameter X1 > the preset freezing threshold X, it means that there is ice on the water collection chassis 6, the drainage hole is blocked, and the outdoor unit is in a frozen state. The defrosting mode needs to be triggered by the control unit.

[0086] When the defrosting mode is activated, the second valve 28 and the third valve 72 are opened (if the first valve is provided, the first valve is also opened simultaneously), connecting the liquid inlet pipe 21 and the liquid outlet pipe 23. The liquid outlet pipe 23 is connected to the water collection pan 6. The flow rates of the liquid inlet pipe 21 and the liquid outlet pipe 23 are kept the same to prevent changes in the mass of the baffle assembly 2. Only the high-temperature water after heat exchange passes through the liquid storage chamber 22 before being discharged into the water collection pan 6, melting the ice in the water collection pan 6 and clearing the drain hole. The water in the water collection pan 6 can flow out of the drain hole, and the liquid level in the water collection pan 6 is continuously reduced. This state is maintained until the current freezing parameter X1 is less than or equal to the preset freezing threshold X. At this time, the second valve 28 and the third valve 72 are closed (if the first valve is provided, the first valve is also closed simultaneously), closing the liquid inlet pipe 21 and the liquid outlet pipe 23.

[0087] If the current vibration parameter L1 is greater than the preset vibration threshold L, and the current freezing parameter X1 is greater than the preset freezing threshold X, it means that the strain of the partition assembly 2 exceeds the standard and the water collection base 6 is frozen. The outdoor unit is in a resonant freezing state and the deicing and noise reduction mode needs to be triggered by the control unit.

[0088] When de-icing and noise reduction mode is activated, in some embodiments of the present application, second valve 28 is first closed, closing liquid outlet pipe 23. Third valve 72 is then opened (if provided, the first valve is also opened simultaneously), connecting liquid inlet pipe 21. The heat-exchanged liquid is then pumped to liquid storage chamber 22 within baffle assembly 2 via pump assembly 7 and heat absorption assembly 5, increasing the mass of baffle assembly 2 until the current vibration parameter L1 is less than or equal to the preset vibration threshold L. Then open the second valve member 28, open the liquid outlet pipe 23, connect the liquid outlet pipe 23 with the water collecting bottom plate 6, keep the flow rate of the liquid inlet pipe 21 and the liquid outlet pipe 23 the same, avoid changes in the mass of the partition assembly 2, and affect the natural frequency of the partition assembly 2. Keep the liquid inlet pipe 21 and the liquid outlet pipe 23 open and with the same flow rate until the current freezing parameter X1 ≤ the preset freezing threshold X; finally, close the second valve member 28 and the third valve member 72 (if the first valve member is provided, the first valve member is also closed synchronously), close the liquid inlet pipe 21 and the liquid outlet pipe 23, and realize the noise reduction and ice-melting functions of the outdoor unit in turn.

[0089] In other embodiments of the present application, when the de-icing and noise reduction mode is activated, the second valve 28 and the third valve 72 are simultaneously opened (if the first valve is provided, the first valve is also opened simultaneously), connecting the liquid inlet pipe 21 and the liquid outlet pipe 23. The liquid outlet pipe 23 is connected to the water collection pan 6, but the flow rate of the liquid inlet pipe 21 is greater than the flow rate of the liquid outlet pipe 23. This increases the mass of the partition assembly 2 while simultaneously feeding the heat-exchanged liquid into the water collection pan 6, thereby simultaneously achieving the noise reduction and de-icing functions of the outdoor unit. After operating in this mode for a period of time, if the current freezing parameter X1 ≤ the preset freezing threshold X, and the current vibration parameter L1 > the preset vibration threshold L, the second valve 28 is first closed, closing the liquid outlet pipe 23 until the current vibration parameter L1 ≤ the preset vibration threshold L. Then, the third valve 72 is closed (if the first valve is provided, the first valve is also closed simultaneously), closing the liquid inlet pipe 21. If the current vibration parameter L1 ≤ the preset vibration threshold L, and the current freezing parameter X1 > the preset freezing threshold X, the opening of the third valve component 72 is adjusted to reduce the flow rate of the liquid inlet pipe 21 to the same as the flow rate of the liquid outlet pipe 23. This state is maintained until the current freezing parameter X1 ≤ the preset freezing threshold X, and then the second valve component 28 and the third valve component 72 are synchronously closed (if a first valve component is provided, the first valve component is also closed synchronously).

[0090] Through the above control method, the noise reduction function or ice-melting function of the outdoor unit can be realized separately, or the noise reduction and ice-melting functions can be realized in sequence or simultaneously; when ice-melting, the waste heat of the compressor 4 can be recovered and utilized through the heat absorption component 5, which is beneficial to reducing the energy consumption of the air-conditioning system caused by ice-melting.
