Any implementation described as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, for purposes of explanation, specific details are set forth. It is apparent to those skilled in the art that the present application can be practiced without using these specific details.

Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.
[0039] In conjunction with Figure 1 and Figure 2 As shown in the drawings, the present application proposes a refrigeration system applied to a refrigerator 100, comprising:
[0040] A distributor 10 for distributing refrigerant;
[0041] A first throttling element 20 is connected to the distributor 10; the first throttling element 20 has a first pipe interface 21, and the refrigerant in the distributor 10 enters the first throttling element 20 through the first pipe interface 21;
[0042] A second throttling element 30 is connected to the distributor 10; the second throttling element 30 has a second pipe interface 31, and the refrigerant in the distributor 10 enters the second throttling element 30 through the second pipe interface 31; the second pipe interface 31 is higher than the first pipe interface 21;
[0043] A refrigeration evaporator 40 is connected to the first throttling element 20;
[0044] A freezing evaporator 50 is connected to the second throttling element 30.
[0045] In the technical scheme of the embodiment, the distributor 10 distributes the refrigerant into the first throttling element 20 and the second throttling element 30 for temperature reduction and pressure reduction, and then the refrigerant flows into the refrigeration evaporator 40 and the freezing evaporator 50 respectively to provide refrigeration. Since the first pipe interface 21 of the first throttling element 20 connected to the distributor 10 is lower than the second pipe interface 31 of the second throttling element 30 connected to the distributor 10, the amount of refrigerant distributed to the refrigeration evaporator 40 is greater than the amount of refrigerant distributed to the freezing evaporator 50, so that the refrigeration evaporator 40 can distribute more refrigerant, thereby improving the refrigeration effect of the refrigeration system at high ambient temperature.
[0046] When the liquid level of the refrigerant in the distributor is low, the refrigerant can only enter the first capillary tube through the first pipe interface 21, and then enter the refrigeration evaporator 40 after passing through the first capillary tube, and evaporate in the refrigeration evaporator 40 to provide refrigeration effect for the refrigeration liner 130. When the liquid level of the refrigerant in the distributor is high, the refrigerant can enter the first capillary tube through the first pipe interface 21 or enter the second capillary tube through the second pipe interface 31, and since the first pipe interface 21 is lower than the second pipe interface 31, the pressure of the first pipe interface 21 is greater, so that the refrigeration evaporator 40 can distribute more refrigerant; the refrigerant passing through the first capillary tube enters the refrigeration evaporator 40, evaporates in the refrigeration evaporator 40 to provide refrigeration effect for the refrigeration liner 130; and the refrigerant passing through the second capillary tube enters the freezing evaporator 50, evaporates in the freezing evaporator 50 to provide refrigeration effect for the freezing liner 140.
[0047] In the embodiment, the distributor has a cavity 12 for containing the refrigerant. The shape of the distributor is not limited, which can be cylindrical, oval, square or funnel-shaped, etc. The size of the distributor is not limited, which is mainly set according to the actual refrigeration demand of the refrigeration system.
[0048] In the above embodiment, the specific structure of the refrigeration evaporator 40 and the freezing evaporator 50 is selected according to the refrigeration demand, which can be a plate heat exchanger or a tube heat exchanger.
[0049] In the above embodiment, the first throttling element 20 and the second throttling element 30 can be one of a capillary tube or an expansion valve. For example, the first throttling element 20 and the second throttling element 30 are capillary tubes; that is, the first throttling element 20 is a first capillary tube, and the second throttling element 30 is a second capillary tube. For another example, the first throttling element 20 and the second throttling element 30 are expansion valves. For yet another example, one of the first throttling element 20 and the second throttling element 30 is a capillary tube, and the other is an expansion valve.
[0050] As shown in Figure 2 , the first pipe joint 21 and the second pipe joint 31 are both arranged on the wall 13 of the distributor 10, and the first pipe joint 21 is arranged lower than the second pipe joint 31. For example, the distributor is vertically placed, and the height of the second pipe joint 31 can be 5-20 mm higher than the height of the first pipe joint 21. The height difference between the two is also set according to the actual refrigeration demand of the refrigeration system, and thus is not limited.
[0051] As shown in Figure 3 , as an optional implementation of the above embodiment, the first pipe joint 21 and the second pipe joint 31 both extend to the inside of the cavity 12 of the distributor 10. In this embodiment, the first pipe joint 21 is arranged closer to the bottom of the cavity 12, and the second pipe joint 31 is arranged farther away from the bottom of the cavity 12; the height difference between the two is also set according to the actual refrigeration demand of the refrigeration system, and thus is not limited.
[0052] As an optional implementation of the above embodiments, a movable sleeve 90 is fitted around the outside of at least one of the first pipe interface 21 and the second pipe interface 31. The movable sleeve 90 is configured to slide along the extending direction of at least one of the first pipe interface 21 and the second pipe interface 31, and one of the first pipe interface 21 and the second pipe interface 31 is connected to the interior of the cavity 12 through the movable sleeve 90. In this embodiment, by setting the movable sleeve 90, the height difference between the first pipe interface 21 or the second pipe interface 31 and the refrigerant liquid level can be adjusted, thereby adjusting the refrigerant distribution so that the refrigeration system can adapt to more refrigeration needs. For example, the movable sleeve 90 is fitted at the second pipe interface 31. When the movable sleeve 90 moves, the inlet of the movable sleeve 90 serves as the inlet for refrigerant to enter the second pipe interface 31, and there is a height difference with the refrigerant liquid level, which can adjust the refrigerant distribution so that the refrigeration system can adapt to more refrigeration needs; when more refrigerant needs to be distributed to the evaporator 50, the height difference between the second pipe interface 31 and the refrigerant liquid level can be lowered.
[0053] Correspondingly, the movable sleeve 90 can also be fitted onto the first pipe interface 21, or both the first pipe interface 21 and the second pipe interface 31 can be fitted with the movable sleeve 90. The movement of the movable sleeve 90 is provided by a motor, for example, the motor drives the movable sleeve 90 to move through a linear transmission mechanism.
[0054] As an optional implementation of the above embodiments, such as Figure 4 and Figure 5 As shown, one of the first tube interface 21 and the second tube interface 31 extends into the cavity 12 of the dispenser 10, and the other connects to the wall 13 of the dispenser 10 and communicates with the cavity 12 of the dispenser 10. For example, as Figure 5 As shown, the first tube interface 21 is located on the wall 13 of the dispenser 10; the second tube interface 31 extends into the cavity 12 of the dispenser 10. For example, the first tube interface 21 extends into the cavity 12 of the dispenser 10, and the second tube interface 31 is located on the wall 13 of the dispenser 10.
[0055] As an optional implementation of the above embodiments, such as Figure 5 As shown, the second tube interface 31 extends into the cavity 12 of the dispenser 10, and a movable sleeve 90 is fitted around the outside of the second tube interface 31. The movable sleeve 90 is configured to slide along the extending direction of the second tube interface 31, and the second tube interface 31 communicates with the interior of the cavity 12 through the movable sleeve 90. For example, as... Figure 5As shown, the movable sleeve 90 is fitted at the second pipe interface 31. When the movable sleeve 90 moves, the inlet of the movable sleeve 90 serves as the inlet for refrigerant to enter the second pipe interface 31, and there is a height difference between the movable sleeve 90 and the refrigerant liquid level, which can adjust the distribution of refrigerant so that the refrigeration system can adapt to more refrigeration needs. When more refrigerant needs to be distributed to the freezer evaporator 50, the height difference between the second pipe interface 31 and the refrigerant liquid level can be lowered.
[0056] As an optional implementation of the above embodiments, such as Figure 4 As shown, a valve plate 22 is provided on the first pipe interface 21. The valve plate 22 has a first state and a second state. In the first state, the valve plate 22 connects the first throttling element 20 to the distributor 10. In the second state, the valve plate 22 disconnects the first throttling element 20 from the distributor 10. In some cases, the refrigeration system needs to allocate more refrigerant to the evaporator 50. For example, when rapid freezing or deep freezing is required, the valve plate 22 is in the closed state, and the refrigerant flows directly into the evaporator 50 to meet the refrigeration requirements of rapid freezing or deep freezing. During normal operation, the valve plate 22 is in the open state.
[0057] The valve plate 22 can be connected to the first pipe interface 21 via a hinge, allowing the valve plate 22 to rotate around the hinge, thereby switching between the first and second states. Alternatively, the valve plate 22 can be configured to slide and connect to the first pipe interface 21, allowing the valve plate 22 to slide and switch between the first and second states.
[0058] As an optional implementation of the above embodiments, such as Figure 1 As shown, the outlet of the refrigerated evaporator 40 is connected to the inlet of the refrigerated evaporator 50, and the outlet of the refrigerated evaporator 50 is connected to the first refrigerant line 561. In this embodiment, the refrigerant from the outlet of the refrigerated evaporator 40 can enter the refrigerated evaporator 50 and then be discharged from the refrigerated evaporator 50 into the first refrigerant line 561.
[0059] like Figure 6 As shown, the outlet of the refrigerated evaporator 40 is connected to the outlet of the refrigerated evaporator 50 via a second refrigerant line 562. The refrigerant that has undergone heat exchange in the refrigerated evaporator 40 and the refrigerant that has undergone heat exchange in the refrigerated evaporator 50 are discharged together into the second refrigerant line 562.
[0060] like Figure 1 and Figure 6 As shown, the first refrigerant line 561 or the second refrigerant line 562 is connected to the compressor 60 so that the refrigerant after cooling can re-enter the compressor 60 to participate in the next cycle.
[0061] In either of the above two structural forms, the implementers can configure the system according to the actual cooling requirements.
[0062] As an optional implementation of the above embodiments, such as Figure 1 and Figure 6 As shown, the refrigeration system also includes a compressor 60, which is connected to the distributor 10. The outlet of the compressor 60 is connected to the inlet of the condenser 70, the outlet of the condenser 70 is connected to the inlet of the dryer filter 80, and the outlet of the dryer filter 80 is connected to the refrigerant inlet 11 of the distributor.
[0063] The first refrigerant line 561 is connected to the compressor 60, and the first refrigerant line 561 is configured to exchange heat with the first throttling element 20 and / or the second throttling element 30; or the second refrigerant line 562 is connected to the compressor 60, and the second refrigerant line 562 is configured to exchange heat with the first throttling element 20 and / or the second throttling element 30.
[0064] In this embodiment, the refrigerant in the first refrigerant line 561 or the second refrigerant line 562 can absorb heat from the first throttling element 20 and / or the second throttling element 30, resulting in a lower temperature of the refrigerant passing through the first throttling element 20 and / or the second throttling element 30. Meanwhile, the refrigerant in the first refrigerant line 561 or the second refrigerant line 562 has a higher temperature and more gaseous components, reducing the risk of liquid slugging in the compressor 60.
[0065] In this embodiment, the refrigerant in the first refrigerant line 561 or the second refrigerant line 562 can be disposed close to the first throttling element 20 and / or the second throttling element 30 respectively, so as to exchange heat by thermal radiation; the refrigerant in the first refrigerant line 561 or the second refrigerant line 562 can be disposed in contact with the first throttling element 20 and / or the second throttling element 30 respectively, so as to exchange heat by heat transfer.
[0066] In other embodiments, such as Figure 7 In the structural configuration shown, the refrigerant flowing out of the refrigeration evaporator 40 and the freezing evaporator 50 may flow directly into the compressor 60 without exchanging heat with the first throttling element 20 and / or the second throttling element 30.
[0067] The refrigeration principle of the refrigeration system provided in this embodiment is as follows: the compressor 60 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant enters the condenser 70 through a pipeline. In the condenser 70, the high-temperature, high-pressure gaseous refrigerant condenses and then enters the distributor (or it can enter the dryer filter 80 and then the distributor). When the refrigerant liquid level in the distributor is low, the refrigerant can only enter the first capillary tube through the first pipe interface 21. After passing through the first capillary tube, it enters the refrigeration evaporator 40, where it absorbs heat and evaporates, providing a cooling effect for the refrigeration inner liner 130. When the refrigerant level in the distributor is high, the refrigerant can enter the first capillary tube through the first pipe interface 21 or the second capillary tube through the second pipe interface 31. Since the first pipe interface 21 is lower than the second pipe interface 31, the pressure at the first pipe interface 21 is higher, resulting in more refrigerant being distributed to the refrigeration evaporator 40. The refrigerant after passing through the first capillary tube enters the refrigeration evaporator 40, where it absorbs heat and evaporates, providing cooling for the refrigerator liner 130. The refrigerant after passing through the second capillary tube enters the freezing evaporator 50, where it absorbs heat and evaporates, providing cooling for the freezing liner 140. The gaseous refrigerant evaporated in the refrigeration evaporator 40 and freezing evaporator 50 returns to the compressor 60 through the refrigerant branch, completing one refrigeration cycle.
[0068] In this embodiment, the compressor 60 can be a rotary compressor 60 or a reciprocating compressor 60.
[0069] This application also proposes a refrigerator 100, including a cabinet and a refrigeration system. The refrigeration system adopts some or all of the technical solutions in the foregoing embodiments to possess some or all of the technical advantages of the foregoing embodiments. The cabinet is provided with a refrigerator liner 130 and a freezer liner 140. The refrigerator evaporator 40 is configured to provide cooling capacity to the refrigerator liner 130; the freezer evaporator 50 is configured to provide cooling capacity to the freezer liner 140.
[0070] Figure 8An example of a frost-free refrigerator 100 is provided, which includes a refrigeration fan 110 and a freezing fan 120. The installation structure of the refrigeration fan 110 and the freezing fan 120, as well as their corresponding air duct structures, are not the focus of this application and can therefore be based on existing technologies. In this embodiment, the refrigeration fan 110 is configured to supply the cooling capacity of the refrigeration evaporator 40 to the refrigeration liner 130, i.e., to drive the air in the refrigeration liner 130 to exchange heat with the refrigeration evaporator 40, thereby lowering the temperature in the refrigeration liner 130. The freezing fan 120 is configured to supply the cooling capacity of the freezing evaporator 50 to the freezing liner 140, i.e., to drive the air in the freezing liner 140 to exchange heat with the freezing evaporator 50, thereby lowering the temperature in the freezing liner 140.
[0071] In some other embodiments, the refrigerator 100 may also be a direct-cooling refrigerator 100, that is, the refrigeration evaporator 40 and the freezing evaporator 50 are respectively fixed on the walls of the refrigeration inner liner 130 and the freezing inner liner 140 to cool the refrigeration inner liner 130 and the freezing inner liner 140 respectively.
[0072] In some other embodiments, the refrigerator 100 may include only a refrigeration fan 110, while the freezer liner 140 is directly cooled. That is, the refrigeration fan 110 is configured to provide the cooling capacity of the refrigeration evaporator 40 to the refrigeration liner 130, i.e., to drive the air in the refrigeration liner 130 to exchange heat with the refrigeration evaporator 40, thereby lowering the temperature in the refrigeration liner 130; while the freezer evaporator 50 is fixed to the wall of the freezer liner 140 to cool the freezer liner 140.
[0073] In some other embodiments, the refrigerator 100 may include only the refrigeration fan 120, while the refrigerator liner 130 is directly cooled. That is, the refrigeration fan 120 is configured to supply the cooling capacity of the evaporator 50 to the refrigerator liner 140, driving the air in the refrigerator liner 140 to exchange heat with the evaporator 50, thereby lowering the temperature in the refrigerator liner 140. The refrigerator evaporator 40 is fixed to the wall of the refrigerator liner 130 to cool the refrigerator liner 130.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
