Abstract

The utility model discloses a refrigeration system and refrigeration equipment, and belongs to the field of compression refrigeration. The refrigerating system provided by the embodiment of the utility model comprises a liquid storage device, an air inlet pipeline, a flow divider and an evaporator. The side wall of the part, located in the liquid storage device, of the air inlet pipeline is provided with an open hole, and the flow dividing piece is fixedly connected with the air inlet pipeline at the open hole.

[0034] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. 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] 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 .

[0036] 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.

[0037] 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.

[0038] 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.

[0039] The present application provides a refrigeration system, which can be integrated into a refrigeration device. Figure 2 , Figure 2 1 is a cross-sectional view of a refrigeration system provided in an embodiment of the present application. The refrigeration system 000 may include: a liquid storage tank 100, an air intake pipeline 200, a flow divider 300 and an evaporator 400.

[0040] The liquid reservoir 100 in the refrigeration system 000 may have: a liquid storage chamber 110, and an air inlet 1 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 400 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 400, resulting in liquid mixed in the gaseous refrigerant provided by the evaporator 400. These liquids can be stored 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.

[0041] A portion of the air intake pipe 200 in the refrigeration system 000 may extend into the liquid storage chamber 110 through the air intake port A1, another portion of the air intake pipe 200 may be located outside the liquid storage chamber 110, and the side wall of the portion of the air intake pipe 200 located in the liquid storage chamber 110 may have an opening B1.

[0042] One end of the air intake pipe 200 in the refrigeration system 000 that is away from the accumulator 100 is in communication with the evaporator 400 .

[0043] The flow divider 300 in the refrigeration system 000 is fixedly connected to the air inlet pipeline 200 at the opening B1 , and the flow divider 300 has a plurality of through holes C1 , each of which is used to connect the liquid storage chamber 110 and the air inlet pipeline 200 .

[0044] In the embodiment of the present application, since the separator 300 can be fixedly connected to the intake pipe 200 at the opening B1 of the intake pipe 200, and a plurality of through holes C1 are provided on the separator 300, the portion of the intake pipe 200 extending into the liquid storage chamber 110 can be connected to the liquid storage chamber 110 through the through holes C1.

[0045] In this case, when the evaporator 400 stops working and there is still some residual gas in the intake pipe 200 that has not been discharged, since the liquid storage chamber 110 and the intake pipe 200 can be connected through multiple through holes C1, the airflow in the intake pipe 200 will be divided into multiple airflows with smaller force by the multiple through holes C1 and then injected into the liquid storage chamber 110. In this way, the probability of each airflow with smaller force injected into the liquid storage chamber 110 generating bubbles in the liquid stored therein is small, thereby effectively reducing the bubbling noise generated in the liquid storage chamber 110, so that the reliability of the refrigeration system 000 is higher.

[0046] In summary, the refrigeration system provided in the embodiment of the present application includes: a liquid reservoir, an air intake pipeline, a diverter and an evaporator. The side wall of the portion of the air intake pipeline located in the liquid reservoir is provided with an opening, and the diverter is fixedly connected to the air intake pipeline at the opening. Since the liquid storage chamber and the air intake pipeline can be connected through a plurality of through holes provided on the diverter, the airflow in the air intake pipeline will be diverted into a plurality of smaller airflows by the plurality of through holes and then injected into the liquid storage chamber. In this way, the probability of each smaller airflow injected into the liquid storage chamber generating bubbles in the liquid stored therein is small, thereby effectively reducing the bubbling noise generated in the liquid storage chamber, making the reliability of the refrigeration system higher.

[0047] In the embodiment of the present application, the liquid collected and stored in the liquid storage chamber 110 can flow to the air intake pipe 200 through the various through holes C1 set on the diverter 300, so that the liquid can also flow back to the evaporator 300 through the air intake pipe 200. The evaporator 300 can convert the liquid into gas again and re-inject the gas into the liquid storage chamber 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] In the present application, the number of through holes C1 provided on the diverter 300 can be appropriately increased so that the sum of the opening surface areas of the through holes C1 provided on the diverter 300 is greater than or equal to the opening surface area of ​​the reference opening. Here, the reference opening can be the oil return hole in the aforementioned related art. In this case, it can be ensured that the flow rate of the oil return is high during the process of the liquid stored in the liquid storage chamber 110 returning the oil through the through holes C1 provided on the diverter 300 and the air intake line 200, thereby ensuring that the bubbling noise generated in the liquid storage chamber 110 is reduced while the flow rate of the liquid stored in the liquid storage chamber 110 returning the oil is basically unchanged relative to the related art.

[0049] Optionally, the inner diameter of each through hole C1 ranges from 0.3 mm to 1 mm.

[0050] Exemplarily, when the inner diameter of the through hole C1 is greater than 1 mm, the airflow force passing through each through hole C1 is still relatively large, so that after the airflow is injected into the liquid storage cavity, bubbles are still generated in the liquid stored in the liquid storage cavity. When the inner diameter of the through hole C1 is less than 0.3 mm, the presence of impurities in the liquid stored in the liquid storage cavity 110 may easily clog the through hole C1, making it difficult for the liquid stored in the liquid storage cavity 110 to flow back into the air intake pipe 200 through the through hole C1, resulting in poor reflux of the liquid in the liquid storage cavity 110. For this reason, when the inner diameter of the through hole C1 is between 0.3 mm and 1 mm, it can be ensured that the through hole C1 can ensure that the airflow force passing through each through hole C1 is relatively small, and can also improve the smoothness of the liquid stored in the liquid storage cavity 110 flowing back into the air intake pipe 200.

[0051] Optionally, refer to Figure 3 , Figure 3 It is a schematic diagram of the three-dimensional structure of an air intake pipeline provided in an embodiment of the present application. Each through hole C1 can be a circular opening or a regular polygonal opening. Here, when the circular and regular polygonal openings are produced and manufactured in the diverter 300, when the through holes C1 are opened, since the through holes C1 are all holes of the same shape, only one opening mold is needed in the production process to open circular holes or regular polygonal holes of the same shape on the diverter 300, making the opening step of the diverter 300 simpler. In addition, when each through hole C1 is a circular hole, the circular hole has less material removal and is more beautiful after molding; when each through hole C1 is a regular polygonal hole, each through hole C1 of the regular polygon can be arranged closer to each other, thereby increasing the total area of ​​the multiple through holes C1, which is more helpful to increase the reflux effect of the through holes C1 on the liquid stored in the liquid storage chamber 110.

[0052] Optionally, refer to Figure 3 , multiple through holes C1 are evenly distributed on the diverter 300. Here, there are multiple possible implementations for the distribution of the oil return holes on the diverter 300. For example, here, the through holes C1 can be circular holes, and multiple circular through holes C1 can be generally distributed in a circular shape at equal intervals on the diverter 300. Here, when the liquid in the liquid storage chamber 110 flows back to the air intake pipe 200 through the through holes C1, the fluids in each through hole C1 will not interfere with each other when flowing, which reduces the noise caused by the impact between liquids in different flow directions when the liquid in the liquid storage chamber 110 flows back to the air intake pipe 200 through the through holes C1, thereby improving the reliability of the refrigeration system 000.

[0053] Optionally, refer to Figure 3 and Figure 4 , Figure 4: is a cross-sectional schematic diagram of a flow divider provided in an embodiment of the present application. The flow divider 300 may include: a flow divider body 320, and an annular protrusion 310 fixedly connected to the periphery of the flow divider body 320. The flow divider body 320 has a plurality of through holes C1, and the outer wall of the flow divider body 320 is fixedly connected to the inner wall of the opening B1, and the annular protrusion 310 is distributed outside the opening B1 and abuts against the side wall of the intake pipe 200.

[0054] For example, the inner ring of the annular protrusion 310 can be fixedly connected to the outer side wall of the diverter body 320, and the portion of the diverter body 320 that is not connected to the annular protrusion 310 can extend into the opening B1 and can be fixedly connected to the intake pipe 200 in the opening B1, while the annular protrusion 310 will not extend into the opening B1. In this case, through the limiting effect of the annular protrusion 310, it can be ensured that during the assembly process of the diverter 300 and the intake pipe 200, the diverter 300 will not be completely inserted into the intake pipe 200 from the opening B1 of the intake pipe 200, thereby ensuring that the diverter 300 can be accurately fixed in the opening B1.

[0055] In the present application, the annular protrusion 310 can be fixedly connected with the opening B1 in the opening B1 by interference fit, or a snap-fit ​​structure can be provided between the outer wall of the annular protrusion 310 and the inner wall of the opening B1 so that the two can be connected by the snap-fit ​​structure.

[0056] Optionally, the splitter body 320 and the annular protrusion 310 in the splitter 300 may be an integral structure, that is, the splitter body 320 and the annular protrusion 310 may be formed simultaneously by the same processing technology.

[0057] In the examples of this application, please refer to Figure 5 , Figure 5 yes Figure 3 The refrigeration system 000 further includes a sealing ring 700 located between the outer side wall of the annular protrusion 310 and the inner side wall of the opening.

[0058] Exemplarily, the sealing ring 700 may be located at the gap between the outer wall of the annular protrusion 310 and the inner wall of the opening B1. It should be noted that, through the sealing effect of the sealing ring 700, it is also possible to reduce the gas in the air intake line 200 from entering the air intake line 200 through the gap between the outer wall of the annular protrusion 310 and the inner wall of the opening B1, thereby reducing the generation of bubble noise in the liquid stored in the liquid storage chamber 110.

[0059] Optionally, refer to Figure 6 , Figure 6It is a cross-sectional view of another refrigeration system provided by an embodiment of the present application, and the liquid storage device 100 further has: an air outlet A2 which is connected to the liquid storage chamber 110 and arranged opposite to the air inlet A1. For the portion of the air inlet pipeline 200 extending into the liquid storage chamber 110 through the air inlet A1, the direction of the end port of this portion of the air inlet pipeline 200 away from the evaporator 400 may be different from the direction of the air outlet A2 of the liquid storage chamber 110.

[0060] For example, the portion of the air inlet pipe 200 extending into the liquid storage chamber 110 through the air inlet A1 can be designed to be bent to a certain extent, so that the port orientation of this portion of the air inlet pipe 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 inlet pipe 200 will not directly face the air outlet A2, so as to ensure that the liquid carried in the airflow will not directly pass through the air outlet A2, thereby ensuring that the liquid can be stored in the liquid storage chamber 110.

[0061] Optionally, refer to Figure 6 The refrigeration system 000 may further include: an air outlet pipeline 500 and a compressor 600. One end of the air outlet pipeline 500 is connected to the liquid storage chamber 110 at the air outlet A2, and the other end of the air outlet pipeline 500 may be connected to the compressor 600.

[0062] In the present application, during the operation of the refrigeration system 000, the evaporator 400 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.

[0063] In the examples of this application, please refer to Figure 7 , Figure 7 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 800 , an expansion valve 900 , a first connecting pipe 1000 , a second connecting pipe 1100 and a third connecting pipe 1200 .

[0064] Among them, the two ends of the first connecting pipe 1000 are respectively connected and communicated with the compressor 600 and the condenser 800; the two ends of the second connecting pipe 1100 are respectively connected and communicated with the condenser 800 and the expansion valve 900; the two ends of the third connecting pipe 1200 are respectively connected and communicated with the evaporator 400 and the expansion valve 900.

[0065] In this case, the evaporator 400 is responsible for converting the liquid refrigerant into a gaseous refrigerant through the evaporation effect of the evaporator 400 , and discharging the converted gas into the liquid storage chamber 110 provided in the liquid storage 100 . Here, the changes of the gas in the evaporator 400 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 400 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 800 through the first connecting pipe 1000; the condenser 800 is used to exchange heat between the high-temperature and high-pressure gas and the outside, so that the gas releases heat and liquefies, and then transports the low-temperature and high-pressure liquid to the expansion valve 900 through the second connecting pipe 1100 for pressure reduction and flow regulation; after the expansion valve 900 completes the regulation, it transports the low-temperature and low-pressure liquid to the evaporator 400 through the third connecting pipe 1200, and the evaporator 400 then converts the liquid into gas through the evaporation action of the evaporator 400 to complete a refrigeration work cycle.

[0066] For example, the evaporator 400 can be set near the position where the refrigeration equipment needs to be cooled, and the evaporator 400 needs to absorb heat from the external environment during the process of evaporating the liquid refrigerant. The evaporator 400 can absorb heat at the position where the refrigeration equipment needs to be cooled during the refrigeration cycle, thereby cooling the refrigeration equipment.

[0067] In summary, the refrigeration system provided in the embodiment of the present application includes: a liquid reservoir, an air intake pipeline, a diverter and an evaporator. The side wall of the portion of the air intake pipeline located in the liquid reservoir is provided with an opening, and the diverter is fixedly connected to the air intake pipeline at the opening. Since the liquid storage chamber and the air intake pipeline can be connected through a plurality of through holes provided on the diverter, the airflow in the air intake pipeline will be diverted into a plurality of smaller airflows by the plurality of through holes and then injected into the liquid storage chamber. In this way, the probability of each smaller airflow injected into the liquid storage chamber generating bubbles in the liquid stored therein is small, thereby effectively reducing the bubbling noise generated in the liquid storage chamber, making the reliability of the refrigeration system higher.

[0068] 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.

[0069] 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.
