In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense.

[0037] Please refer to Figure 1 , Figure 1 The refrigeration system 00 may include a liquid storage tank 01 , an air intake pipe 02 and an evaporator 03 .

[0038] The liquid reservoir 01 may have a liquid storage chamber 01a. Here, a portion of the air intake line 02 is located in the liquid storage chamber 01a, and an oil return hole 02a is provided on the outer wall of the portion of the air intake line 02 located in the liquid storage chamber 01a. Another portion of the air intake line 02 is located outside the liquid storage chamber 01a, and the end of the air intake line 02 away from the liquid reservoir 01 is connected to the evaporator 03.

[0039] During the operation of the refrigeration system 00, the liquid reservoir 01 can store the liquid components (usually including: liquid refrigerant and liquid lubricating oil) carried in the gas sprayed from the evaporator 03, and these liquids can flow back to the evaporator 03 through the oil return hole 02a and the air intake pipe 02. The evaporator 03 can convert these liquids into gases again and then re-inject these gases into the liquid reservoir 01, so that the liquid stored in the liquid storage chamber 01a can participate in the subsequent refrigeration cycle in the refrigeration system 00.

[0040] However, within a short period of time after the refrigeration system 00 stops working, there will still be some gas in the air intake pipe 02 that has not been discharged in time, and these gases will still be injected into the liquid storage chamber 01a, but these gases will not enter the subsequent circulation process. Therefore, these gases can not only be injected into the liquid storage chamber 01a through the port in the air intake pipe 02 that extends into the liquid storage chamber 01a, but also can be injected into the liquid storage chamber 01a through the oil return hole 02a. Because liquid is stored in the liquid storage chamber 01a, after gas is injected into the liquid storage chamber 01a through the oil return hole 02a, bubbles will be generated in the liquid stored in the liquid storage chamber 01a, resulting in bubbling noise in the liquid storage chamber 01a, which in turn leads to low reliability of the refrigeration system 00.

[0041] The present application provides a refrigeration system, which can be integrated into a refrigeration device. Figure 2 , Figure 2 2 is a cross-sectional view of a refrigeration system provided in the present application. The refrigeration system 000 may include: a liquid storage tank 100 , an air intake line 200 , an evaporator 300 and a one-way flow component 400 .

[0042] The liquid reservoir 100 in the refrigeration system 000 may have: a liquid storage chamber 110, and an air inlet A1 connected to the liquid storage chamber 110. Here, the liquid storage chamber 110 in the liquid reservoir 100 is mainly used to collect liquid (usually including: liquid refrigerant and liquid lubricant). For example, during the normal refrigeration process of the refrigeration system 000, the evaporator 300 will provide a gaseous refrigerant to complete the refrigeration work cycle. During the circulation process, part of the liquid refrigerant fails to be completely vaporized in the evaporator 300, resulting in liquid mixed in the gas provided by the evaporator 300. These liquids can be present in the liquid storage chamber 110 of the liquid reservoir 100 to prevent these liquids from being sucked into other components (for example, a compressor) in the refrigeration system 000, causing damage to the compressor. At the same time, during the circulation process, in order to lubricate and protect the various components in the refrigeration system 000, some gases will carry gaseous lubricants. During the circulation process, part of the gaseous lubricating oil exchanges heat with the external environment or refrigerant and will liquefy into liquid lubricating oil. These liquid lubricating oils can also be stored in the liquid storage chamber 110 of the liquid reservoir 100 to prevent these liquid lubricating oils from being sucked into the compressor in the refrigeration system 000 and causing damage to the compressor.

[0043] A portion of the air intake pipeline 200 in the refrigeration system 000 may extend into the liquid storage chamber 110 through the air intake port A1 , and another portion of the air intake pipeline 200 may be located outside the liquid storage chamber 110 .

[0044] One end of the air intake pipe 200 in the refrigeration system 000 that is away from the liquid storage 100 can be communicated with the evaporator 300. For example, the end of the air intake pipe 200 that is away from the evaporator 300 is located in the liquid storage chamber 110, and the end of the air intake pipe 200 that is away from the evaporator 300 has an end opening C that is communicated with the liquid storage chamber 110. In this way, after the evaporator 300 injects gas into the air intake pipe 200, the gas can be injected into the liquid storage chamber 110 through the end opening C of the air intake pipe 200 that is located in the liquid storage chamber 110.

[0045] One end of the one-way flow component 400 in the refrigeration system 000 can be communicated with the liquid storage chamber 110 , and the other end of the one-way flow component 400 can be communicated with a portion of the air inlet pipeline 200 located outside the liquid storage chamber 110 .

[0046] The one-way flow component 400 may be configured to unidirectionally conduct the fluid in the liquid storage chamber 110 to a portion of the intake pipe 200 located outside the liquid storage chamber 110 .

[0047] In the embodiment of the present application, by connecting one end of the one-way flow component 400 to the liquid storage chamber 110 and the other end to the portion of the intake pipe 200 located outside the liquid storage chamber 110, the liquid collected and stored in the liquid storage chamber 110 can flow to the portion of the intake pipe 200 located outside the liquid storage chamber 110 through the one-way guide 430, so that the liquid can flow back to the evaporator 300. The evaporator 300 can convert the liquid into gas again and then re-inject the gas into the liquid reservoir 100, so that the liquid stored in the liquid storage chamber 110 can participate in the subsequent refrigeration cycle in the refrigeration system 000.

[0048] It should be noted that the one-way flow component 400 can only unidirectionally conduct the fluid in the liquid storage chamber 110 to the portion of the intake pipe 200 located outside the liquid storage chamber 110, while the airflow in the intake pipe 200 and the liquid carried in the airflow cannot enter the liquid storage chamber 110 through the one-way flow component 400. In this case, please refer to Figure 3 , Figure 3 yes Figure 2 The partial enlarged view of the refrigeration system shown in the figure does not need to open the oil return hole on the outer wall of the part of the air intake pipe 200 located in the liquid storage chamber 110, so that the airflow in the air intake pipe 200 can only be injected into the liquid storage chamber 110 through the end opening C located in the liquid storage chamber 110. In this way, after the refrigeration system 000 stops working, even if there is still some gas that has not been discharged in time in the air intake pipe 200, these gases can only be injected into the liquid storage chamber 110 through the end opening C of the air intake pipe 200 located in the liquid storage chamber 110, thereby ensuring that no bubbles are generated in the liquid stored in the liquid storage chamber 110, thereby effectively eliminating the bubbling noise generated in the liquid storage chamber 110, so that the reliability of this refrigeration system 000 is higher.

[0049] It should be noted that by providing a one-way flow component 400 in the refrigeration system 000, the liquid stored in the liquid storage chamber 110 can be discharged to the evaporator 300 in a timely manner through the one-way flow component 400 during the normal operation of the refrigeration system 000 or after the refrigeration system 000 stops working, so that too much liquid will not accumulate in the liquid storage chamber 110.

[0050] In summary, the refrigeration system provided in the embodiment of the present application includes: a liquid reservoir, an air intake pipeline, an evaporator and a one-way flow component. One end of the one-way flow component is connected to the liquid storage chamber in the liquid reservoir, and the other end of the one-way flow component is connected to the portion of the air intake pipeline located outside the liquid reservoir. The one-way flow component can only unidirectionally conduct the fluid in the liquid storage chamber to the portion of the air intake pipeline located outside the liquid storage chamber, while the airflow in the air intake pipeline and the liquid carried in the airflow cannot enter the liquid storage chamber through the one-way flow component. In this case, it is not necessary to open an opening on the outer wall of the portion of the air intake pipeline located in the liquid storage chamber, so that the airflow in the air intake pipeline can only be injected into the liquid storage chamber 110 through the end opening located in the liquid storage chamber. In this way, after the refrigeration system stops working, even if there is still some gas in the air inlet pipe that has not been discharged in time, these gases can only be injected into the liquid storage chamber through the end opening of the air inlet pipe located in the liquid storage chamber, thereby ensuring that no bubbles are generated in the liquid stored in the liquid storage chamber, thereby effectively eliminating the bubbling noise generated in the liquid storage chamber, making the reliability of this refrigeration system higher.

[0051] Optionally, refer to Figure 4 , Figure 4 It is a cross-sectional view of another refrigeration system provided in an embodiment of the present application. The liquid storage device 100 also has: an outlet A2 connected to the liquid storage chamber 110 and arranged opposite to the air inlet A1. The refrigeration system 000 may also include: an outlet pipeline 500 and a compressor 600. Among them, one end of the outlet pipeline 500 is connected to the liquid storage chamber 110 at the outlet A2, and the other end of the outlet pipeline 500 can be connected to the compressor 600.

[0052] In the present application, during the operation of the refrigeration system 000, the evaporator 300 can inject gas into the liquid storage chamber 110 of the liquid reservoir 100 through the air inlet pipe 200, and the gas in the liquid storage chamber 110 can be directly sucked away by the compressor 600 through the air outlet pipe 500, thereby ensuring that the refrigeration system 000 can realize the refrigeration cycle.

[0053] Alternatively, if Figure 4 As shown, the one-way flow component 400 may include: a first pipe 410 and a second pipe 420 , and a one-way conducting member 430 located between the first pipe 410 and the second pipe 420 .

[0054] Among them, the two ends of the one-way conductive member 430 are respectively connected to the ends of the first pipe 410 and the second pipe 420, the end of the first pipe 410 facing away from the one-way conductive member 430 is connected to the liquid storage chamber 110, and the end of the second pipe 420 facing away from the one-way conductive member 430 is connected to the part of the intake pipe 200 located outside the liquid storage chamber 110.

[0055] Exemplarily, after the liquid in the liquid storage chamber 110 enters the first pipe 410 connected to the liquid storage chamber 110, the one-way flow member 430 can conduct the liquid in the first pipe 410 to the second pipe 420, and enter the intake pipe 200 connected to the second pipe 420 through the second pipe 420. After the gas in the intake pipe 200 enters the second pipe 420 connected to the intake pipe 200, since the one-way flow member 430 has the function of unidirectionally conducting the flow, the gas in the second pipe 420 cannot enter the first pipe 410 from the second pipe 420 through the one-way flow member 430. In this way, it can be ensured that the gas in the intake pipe 200 will not be injected into the liquid storage chamber 110 through the one-way flow guide member 400, and further, it can be ensured that no bubbles are generated in the liquid stored in the liquid storage chamber 110.

[0056] Optionally, the one-way conducting member 430 in the one-way flow component 400 may include at least one of a one-way valve and a back pressure valve.

[0057] In the case where the one-way conducting member 430 includes a one-way valve, the fluid inside the one-way valve can only flow in a preset direction and cannot flow in the reverse direction. Here, the fluid inlet of the one-way valve can be connected to the end of the first pipe 410 away from the liquid storage chamber 110, and the fluid outlet of the one-way valve can be connected to the end of the second pipe 420 away from the intake pipeline 200, so that the flow direction of the fluid preset by the one-way valve can be changed to the direction from the first pipe 410 to the second pipe 420.

[0058] In this case, the fluid can enter the second pipeline 420 from the first pipeline 410 through the one-way valve, but the fluid in the second pipeline 420 is blocked by the one-way valve and cannot flow in a direction opposite to the preset direction of the one-way valve, and thus cannot enter the first pipeline 410 from the second pipeline 420 through the one-way valve.

[0059] When the one-way conducting member 430 includes a back-pressure valve, the back-pressure valve will open only when the fluid pressure inside the back-pressure valve is greater than a preset pressure, and the fluid can then flow out from the back-pressure valve outlet.

[0060] Here, the fluid inlet of the back-pressure valve can be connected to the end of the first pipe 410 away from the liquid storage chamber 110, and the fluid outlet of the back-pressure valve can be connected to the end of the second pipe 420 away from the intake pipe 200, and the preset pressure of the back-pressure valve can be adjusted to the gas pressure in the second pipe 420. When the amount of liquid accumulated in the first pipe 410 is large enough to meet the liquid pressure to reach the opening pressure of the back-pressure valve, the back-pressure valve opens. At this time, the liquid in the first pipe 410 can flow into the second pipe 420, while the gas in the second pipe 420 with lower pressure cannot enter the first pipe 410.

[0061] Optionally, see Figure 5 , Figure 5 It is a cross-sectional view of another refrigeration system provided by an embodiment of the present application. The liquid reservoir 100 may have a first opening A3 connected to the liquid storage chamber 110 at a position close to the air inlet A1, and the end of the first pipe 410 facing away from the one-way conducting member 430 may be connected to the liquid reservoir 100 at the first opening A3. The portion of the air intake line 200 located outside the liquid storage chamber 110 may have a second opening B1 connected to the air intake line 200, and the end of the second pipe 420 facing away from the one-way conducting member 430 may be connected to the air intake line 200 at the second opening B1.

[0062] It should be noted that, by setting the first opening A3 at a position close to the air inlet A1 in the liquid reservoir 100, when the liquid in the liquid storage chamber 110 is separated from the gas, the liquid with higher density can accumulate at the first opening A3 in the liquid storage chamber 110 under the action of gravity; and by setting the second opening B1 in the part of the intake pipe 200 located outside the liquid storage chamber 110, the liquid is stored in the part of the intake pipe 200 located outside the liquid storage chamber 110 after entering the intake pipe 200, thereby reducing the situation in which the compressor is damaged due to the accumulation of liquid in the part of the intake pipe 200 located in the liquid storage chamber 110, and then being directly carried out by the gas in the intake pipe 200 and directly inhaled by the compressor.

[0063] Optionally, see Figure 5 The refrigeration system 000 further includes: a first sealing ring 700 located between the first opening A3 and an end of the first pipe 410 away from the one-way conductive member 430 , and a second sealing ring 800 located between the second opening B1 and an end of the second pipe 420 away from the one-way conductive member 430 .

[0064] Exemplarily, the first sealing ring 700 may be located in the gap between the first opening A3 and the first pipe 410 and the liquid storage chamber 110, and the second sealing ring 800 may be located in the gap between the second opening B1 and the second pipe 420 and the air intake pipe 200. It should be noted that, through the sealing effect of the first sealing ring 700, dust and impurities from the outside can be reduced from entering the gap between the first pipe 410 and the liquid storage chamber 110. Similarly, through the sealing effect of the second sealing ring 800, dust and impurities from the outside can be reduced from entering the gap between the second pipe 420 and the air intake pipe 200. To this end, through the joint effect of the first sealing ring 700 and the second sealing ring 800, the possibility of the refrigerant and lubricating oil in the refrigeration system 000 being contaminated by the outside and deteriorating is reduced.

[0065] Optionally, for the portion of the air intake line 200 extending into the liquid storage chamber 110 through the air intake port A1, the orientation of the end opening C of this portion of the air intake line 200 away from the evaporator 300 may be different from the orientation of the air outlet A2 of the liquid storage chamber 110. For example, the portion of the air intake line 200 extending into the liquid storage chamber 110 through the air intake port A1 may be designed to be bent to a certain extent, so that the orientation of the port of this portion of the air intake line 200 is different from the orientation of the air outlet A2. In this way, it can be ensured that the airflow flowing out through the port of the air intake line 200 will not directly face the air outlet A2, so as to ensure that the liquid carried in the airflow will not be directly sucked away by the compressor 600 through the air outlet A2, thereby ensuring that these liquids can be stored in the liquid storage chamber 110.

[0066] In the examples of this application, please refer to Figure 6 , Figure 6 It is a cross-sectional view of another refrigeration system provided in an embodiment of the present application. The refrigeration system 000 may further include: a condenser 900, an expansion valve 1000, a first connecting pipe 1100, a second connecting pipe 1200 and a third connecting pipe 1300.

[0067] Among them, the two ends of the first connecting pipe 1100 are respectively connected and communicated with the compressor 600 and the condenser 900; the two ends of the second connecting pipe 1200 are respectively connected and communicated with the condenser 900 and the expansion valve 1000; the two ends of the third connecting pipe 1300 are respectively connected and communicated with the evaporator 300 and the expansion valve 1000.

[0068] In this case, the evaporator 300 is responsible for converting the liquid refrigerant into a gaseous refrigerant through the evaporation effect of the evaporator 300 , and discharging the converted gas into the liquid storage cavity provided in the liquid storage 100 . Here, the changes of the gas in the evaporator 300 can be simply summarized as follows: after absorbing the heat of the liquid from the outside, the liquid is converted into a low-temperature and low-pressure gas; the liquid storage 100 is responsible for separating the gas and liquid discharged from the evaporator 300 into the liquid storage chamber 110, and storing the liquid carried in the low-temperature and low-pressure gas, and finally transporting the pure gas to the compressor 600 through the gas outlet pipeline 500; the compressor 600 converts the low-temperature and low-pressure gas into a high-temperature and high-pressure gas by consuming electricity to do work, and then transports it to the condenser 900 through the first connecting pipe 1100; the condenser 900 is used to exchange heat between the high-temperature and high-pressure gas and the outside, so that after the gas releases heat and liquefies, the low-temperature and high-pressure liquid is transported to the expansion valve 1000 through the second connecting pipe 1200 for pressure reduction and flow regulation; after the expansion valve 1000 completes the regulation, the low-temperature and low-pressure liquid is transported to the evaporator 300 through the third connecting pipe 1300, and the evaporator 300 then converts the liquid into gas through the evaporation action of the evaporator 300 to complete a refrigeration work cycle.

[0069] For example, the evaporator 300 can be set near the position where the refrigeration equipment needs to be cooled, and the evaporator 300 needs to absorb heat from the external environment during the process of evaporating the liquid refrigerant. The evaporator 300 can absorb heat at the position where the refrigeration equipment needs to be cooled during the refrigeration cycle, thereby cooling the refrigeration equipment.

[0070] In summary, the refrigeration system provided in the embodiment of the present application includes: a liquid reservoir, an air intake pipeline, an evaporator and a one-way flow component. One end of the one-way flow component is connected to the liquid storage chamber in the liquid reservoir, and the other end of the one-way flow component is connected to the portion of the air intake pipeline located outside the liquid reservoir. The one-way flow component can only unidirectionally conduct the fluid in the liquid storage chamber to the portion of the air intake pipeline located outside the liquid storage chamber, while the airflow in the air intake pipeline and the liquid carried in the airflow cannot enter the liquid storage chamber through the one-way flow component. In this case, it is not necessary to open an opening on the outer wall of the portion of the air intake pipeline located in the liquid storage chamber, so that the airflow in the air intake pipeline can only be injected into the liquid storage chamber 110 through the end opening located in the liquid storage chamber. In this way, after the refrigeration system stops working, even if there is still some gas in the air inlet pipe that has not been discharged in time, these gases can only be injected into the liquid storage chamber through the end opening of the air inlet pipe located in the liquid storage chamber, thereby ensuring that no bubbles are generated in the liquid stored in the liquid storage chamber, thereby effectively eliminating the bubbling noise generated in the liquid storage chamber, making the reliability of this refrigeration system higher.

[0071] The present application also provides a refrigeration device, which may be a device with refrigeration requirements such as an air conditioner or a refrigerator. The refrigeration device may include a device body and a refrigeration system 000 integrated in the device body, and the refrigeration system 000 is the above-mentioned refrigeration system 000. The refrigeration system 000 may be used to refrigerate a location in the device body that requires refrigeration.

[0072] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0073] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
