[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0056] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0057] Figure 1 The present invention is a structural block diagram of a refrigeration device according to an exemplary embodiment. The refrigeration device is used to achieve refrigeration. The refrigeration device can be configured in refrigeration equipment such as a refrigerator, an air conditioner, an ice cream machine, and a freezer.

[0058] As for the compressor 1, the compressor 1 is used to increase the pressure of the refrigerant, so that the volume of the refrigerant is reduced, and the refrigerant is compressed. For example, a driving piston is arranged inside the compressor 1, and the driving piston is driven by a motor to generate reciprocating motion in the cylinder. During the reciprocating motion of the driving piston, the suction end of the compressor 1 can inhale the refrigerant in the low-temperature and low-pressure state, and then compress the refrigerant in the low-temperature and low-pressure state into the refrigerant in the high-temperature and high-pressure state, and finally output the refrigerant in the high-temperature and high-pressure state from the exhaust end of the compressor 1.

[0059] The suction end of the compressor 1 is connected to the output end of the gas leakage pipeline 9, and the exhaust end of the compressor 1 is connected to the first end of the conduction module 2. In this way, the suction end of the compressor 1 can inhale refrigerant from the output end of the gas leakage pipeline 9, and the refrigerant discharged from the exhaust end of the compressor 1 can be transmitted to the first end of the conduction module 2.

[0060] For the conduction module 2, the conduction module 2 has a first end, a second end and a third end. The first end of the conduction module 2 is connected to the exhaust end of the compressor 1, the second end of the conduction module 2 is connected to the input end of the air leakage pipeline 9, and the third end of the conduction module 2 is connected to the condensation pipeline 3.

[0061] The conducting module 2 is used to conduct at least two of the compressor 1, the air leakage pipeline 9 and the condensation pipeline 3. For example, the conducting module 2 has the following three functions.

[0062] First, the conducting module 2 can conduct the exhaust end of the compressor 1 with the gas leakage pipeline 9. For example, when the first end and the second end of the conducting module 2 are conducted, the exhaust end of the compressor 1 can be conducted with the input end of the gas leakage pipeline 9. When the exhaust end of the compressor 1 is conducted with the gas leakage pipeline 9, the refrigerant discharged from the exhaust end of the compressor 1 will enter the gas leakage pipeline 9.

[0063] Secondly, the conducting module 2 can conduct the compressor 1, the air leakage pipeline 9 and the condensing pipeline 3. For example, when the first end, the second end and the third end of the conducting module 2 are interconnected, the exhaust end of the compressor 1, the input end of the air leakage pipeline 9 and the condensing pipeline 3 can be conducted. When the exhaust end of the compressor 1, the air leakage pipeline 9 and the condensing pipeline 3 are interconnected, a part of the refrigerant discharged from the exhaust end of the compressor 1 will enter the air leakage pipeline 9, and the other part will enter the condensing pipeline 3.

[0064] Thirdly, the conducting module 2 can conduct the exhaust end of the compressor 1 with the condensing pipeline 3. For example, when the first end and the third end of the conducting module 2 are conducted, the exhaust end of the compressor 1 and the condensing pipeline 3 can be conducted. When the exhaust end of the compressor 1 and the condensing pipeline 3 are conducted, the refrigerant discharged from the exhaust end of the compressor 1 will enter the condensing pipeline 3.

[0065] For the leak line 9, the input end of the leak line 9 is connected to the second end of the conduction module 2, and the output end of the leak line 9 is connected to the suction end of the compressor 1, for example, the output end of the leak line 9 is connected to the suction end of the compressor 1 and the evaporation line 8. The leak line 9 serves as a refrigerant transmission channel between the exhaust end of the compressor 1 and the suction end of the compressor 1, and can discharge the refrigerant at the exhaust end of the compressor 1 to the suction end of the compressor 1, so that the pressure at the exhaust end of the compressor 1 tends to be consistent with the pressure at the suction end of the compressor 1.

[0066] See also Figure 2As shown, the current refrigeration device includes a compressor 1, a condensing line 3, a condenser 4, a drying filter 5, a capillary tube 6, an evaporator 7 and an evaporating line 8, the exhaust end of the compressor 1 is connected to the condensing line 3, the condensing line 3 is connected to the condenser 4, the condenser 4 is connected to the drying filter 5, the drying filter 5 is connected to the capillary tube 6, the capillary tube 6 is connected to the evaporator 7, and the evaporator 7 is connected to the evaporating line 8.

[0067] The high-temperature and high-pressure gas refrigerant output from the exhaust end of the compressor 1 enters the condenser 4 through the condensation pipeline 3, and is thereby converted into a high-temperature and high-pressure liquid refrigerant; the high-temperature and high-pressure liquid refrigerant is then filtered through the drying filter 5; the opening at the input end of the capillary tube 6 is relatively large, and the opening at the output end of the capillary tube 6 is relatively small, so after the high-temperature and high-pressure liquid refrigerant enters the capillary tube 6, the low-temperature and low-pressure liquid refrigerant will be discharged from the capillary tube 6; the low-temperature and low-pressure liquid refrigerant enters the evaporator 7 and is evaporated, thereby being converted into a low-temperature and low-pressure gas refrigerant; after the low-temperature and low-pressure gas refrigerant enters the compressor 1 through the evaporation pipeline 8, it is compressed by the compressor 1 into a high-temperature and high-pressure gas refrigerant.

[0068] However, in this refrigeration device, the gas refrigerant discharged from the exhaust end of the compressor 1 is in a state of high temperature and high pressure, and the gas refrigerant sucked into the suction end of the compressor 1 is in a state of low temperature and low pressure, so the pressure at the exhaust end of the compressor 1 itself will be greater than the pressure at the suction end of the compressor 1, and under certain operating conditions, the pressure at the exhaust end of the compressor 1 will also be much greater than the pressure at the suction end of the compressor 1.

[0069] For example, during the continuous operation of the compressor 1, since the opening at the input end of the capillary tube 6 is larger and the outlet at the output end of the capillary tube 6 is smaller, the refrigerant in the condensation line 3 connected to the input end of the capillary tube 6 will accumulate, which will cause the pressure at the exhaust end of the compressor 1 to be higher, and the pressure at the exhaust end will also be greater than the pressure at the suction end of the compressor 1.

[0070] For another example, since the higher the temperature, the greater the gas pressure, when the compressor 1 is in a high temperature environment, the pressure of the gas refrigerant on the exhaust end side of the compressor 1 will become greater due to the temperature, and the pressure at the exhaust end will also be greater than the pressure at the suction end of the compressor 1.

[0071] During the operation of the compressor 1, the compressor 1 does not work continuously, but stops working for a certain period of time. For example, during the operation of the compressor 1 of the refrigerator, after the compressor 1 cools the internal temperature of the refrigerator to a specified temperature, the compressor 1 will stop working. When the internal temperature of the refrigerator is higher than the specified temperature, the compressor 1 will be controlled to restart to cool the internal temperature of the refrigerator to the specified temperature. It can be seen that during the operation of the compressor 1, the restart process of the compressor 1 will be involved.

[0072] During the restarting process of compressor 1, if the pressure at the exhaust end of compressor 1 is much greater than the pressure at the suction end of compressor 1, compressor 1 may fail to start. The reason is that a driving piston is provided inside compressor 1. When the driving piston moves from the suction end of compressor 1 to the exhaust end of compressor 1, the high-temperature and high-pressure gas refrigerant in compressor 1 will be discharged from the exhaust end of compressor 1. When the pressure at the suction end of compressor 1 is relatively low, and the pressure at the exhaust end of compressor 1 is relatively high, the driving piston is subjected to relatively low thrust from the suction end of compressor 1 and relatively high resistance from the exhaust end of compressor 1, and it is difficult to discharge the gas inside compressor 1 from the exhaust end of compressor 1, resulting in failure to start compressor 1.

[0073] Based on this, the interval between two consecutive starts of compressor 1 can be increased, and the pressure at the exhaust end of compressor 1 can be slowly released during the interval, thereby reducing the pressure difference between the exhaust end of compressor 1 and the suction end of compressor 1, so that compressor 1 can be started smoothly. However, this solution requires a long time to start compressor 1. For example, it takes 5 to 10 minutes for compressor 1 to release the pressure at the exhaust end, which means that compressor 1 needs to wait 5 to 10 minutes to restart, and it is impossible to achieve a quick response of compressor 1. In the field of refrigerators, if compressor 1 does not work for a long time, the temperature inside the refrigerator may rise, and the refrigerator cannot achieve a good cooling effect.

[0074] The starting current applied to the compressor 1 can also be increased, and a starting current larger than the normal starting current of the compressor 1 can be applied to the compressor 1, so that the compressor 1 based on the larger starting current can drive the piston to discharge the high-temperature and high-pressure gas from the exhaust end of the compressor 1 with a larger torque. However, when the starting current applied to the compressor 1 is large, on the one hand, the compressor 1 may not be able to withstand the large starting current and an overcurrent fault may occur; on the other hand, in order to reduce the overcurrent fault, the current tolerance of the compressor 1 needs to be increased, which leads to an increase in the hardware cost of the compressor 1; on the third hand, applying a larger starting current will also consume more electric energy; on the fourth hand, the compressor 1 is provided with a motor for driving the piston, and the motor is not rigidly connected to the housing of the compressor 1, that is, there is no direct connection point between the motor and the housing of the compressor 1. When the motor receives a larger starting current and the motor cannot start, the motor will shake, and will hit the housing of the compressor 1 during the shaking process, which may cause damage to the motor and / or the housing of the compressor 1.

[0075] In this disclosure, please refer to Figure 1As shown, a conducting module 2 and a bleed pipe 9 can be additionally added to the current refrigeration device. When the conducting module 2 conducts the exhaust end of the compressor 1 and the bleed pipe 9, the refrigerant discharged from the exhaust end of the compressor 1 is discharged to the suction end of the compressor 1 through the bleed pipe 9. In this process, since the pressure at the exhaust end of the compressor 1 is greater than the pressure at the suction end of the compressor 1, based on the large pressure difference on both sides of the compressor, the refrigerant discharged from the exhaust end of the compressor 1 will be more quickly discharged to the suction end of the compressor 1, so that the pressure at the exhaust end of the compressor 1 and the pressure at the suction end of the compressor 1 tend to be consistent. After the pressures on both sides of the compressor 1 tend to be consistent, the thrust of the suction end on the driving piston inside the compressor 1 will increase, and the resistance on the exhaust end will decrease, so that the driving piston can quickly discharge the gas inside the compressor 1 from the exhaust end of the compressor 1, thereby achieving the successful start-up of the compressor 1.

[0076] Firstly, compared with the scheme of increasing the interval time between two adjacent starts of the compressor 1, the scheme of additionally adding the conduction module 2 and the air leakage pipeline 9 utilizes the uneven pressure on both sides of the suction end and the exhaust end of the compressor 1. At the moment when the suction end and the exhaust end of the compressor 1 are connected, the refrigerant discharged from the exhaust end on the high-pressure side of the compressor 1 will be quickly discharged to the suction end of the compressor 1 on the low-pressure side, thereby realizing rapid equalization of the pressure on both sides of the compressor 1. There is no need to wait for the compressor 1 to slowly release the pressure on the exhaust end of the compressor 1, thereby realizing rapid start-up of the compressor 1.

[0077] Secondly, there is no need to increase the starting current applied to the compressor 1, thereby reducing the probability of overcurrent failure, increased hardware cost, power waste, compressor 1 damage, etc.

[0078] Figure 3 and Figure 4 The functional schematic diagram of the conduction module 2 is shown, and the conduction module 2 is used to conduct the exhaust end of the compressor 1 and the air leakage pipeline 9 before the compressor 1 is started, and is used to conduct the exhaust end of the compressor 1 and the condensation pipeline 3 after the compressor 1 is started.

[0079] When the compressor 1 is started, if the pressure difference between the exhaust end and the intake end of the compressor 1 is too large, the compressor 1 may not be started successfully. Therefore, the conduction module 2 needs to conduct the exhaust end of the compressor 1 and the air leakage pipe 9 before the compressor 1 is started, so that the high-temperature and high-pressure refrigerant at the exhaust end of the compressor 1 is discharged to the intake end of the compressor 1 through the air leakage pipe 9, so that the pressure difference between the exhaust end and the intake end of the compressor 1 approaches 0. Only after the pressure difference between the exhaust end and the intake end of the compressor 1 becomes smaller, the compressor 1 can be successfully started.

[0080] After the compressor 1 is started, since the compressor 1 needs to transmit the discharged high-temperature and high-pressure refrigerant to the entire refrigeration circuit, the conduction module 2 needs to connect the exhaust end of the compressor 1 with the condenser. Only then will the refrigerant discharged from the compressor 1 enter the condensation line 3, and pass through the condensation line 3, the condenser 4, the drying filter 5, the capillary tube 6, the evaporator 7, and the evaporation line 8 in sequence and be returned to the suction end of the compressor 1 to complete the refrigeration circuit.

[0081] Optionally, after the compressor 1 is started, the conducting module 2 may further conduct the exhaust end of the compressor 1 with the air leakage pipeline 9 , and conduct the exhaust end of the compressor 1 with the condensation pipeline 3 .

[0082] After the compressor 1 is started, since the input end opening of the capillary tube 6 is larger and the output end opening is smaller, the refrigerant flow rate at the input end of the capillary tube 6 is much larger than the refrigerant flow rate at the output end of the capillary tube 6, which causes the refrigerant in the condensation line 3 on the input end side of the capillary tube 6 to gradually accumulate, so that the pressure at the exhaust end of the compressor 1 will also gradually increase. Based on this, after the compressor 1 is started, the conduction module 2 can conduct the exhaust end of the compressor 1 with the bleed line 9, and the exhaust end of the compressor 1 with the condensation line 3, then part of the refrigerant discharged from the exhaust end of the compressor 1 will be discharged to the suction end of the compressor 1 through the bleed line 9, thereby reducing the pressure at the exhaust end of the compressor 1; the other part will be transmitted back to the entire refrigeration circuit through the condensation line 3 to achieve refrigeration.

[0083] For the conduction module 2, when the conduction module 2 operates with different operating parameters, the air leakage pipeline 9, the compressor 1 and the condensation pipeline 3 in the refrigeration device will be in different conduction states, and the operating parameters include a first operating parameter, a second operating parameter and a third operating parameter, and the first operating parameter, the second operating parameter and the third operating parameter are different. The type of the operating parameter can be the angle reached by the conduction module 2 after rotation, or the voltage applied to the conduction module 2, etc.

[0084] (1) When the conducting module 2 executes the first operating parameter, the exhaust end of the compressor 1 and the air leakage pipeline 9 are connected.

[0085] (2) When the conducting module 2 executes the second operating parameter, the exhaust end of the compressor 1 is conducted with the exhaust pipe 9 , and the exhaust end of the compressor 1 is conducted with the condensation pipe 3 .

[0086] (3) When the conducting module 2 executes the third operating parameter, the exhaust end of the compressor 1 and the condensation pipeline 3 are conducting.

[0087] The conduction module 2 may be a two-position three-way solenoid valve or an electric three-way valve.

[0088] See also Figure 3As shown, taking the conduction module 2 as a two-position three-way solenoid valve, the first operating parameter is the first voltage applied to the two-position three-way solenoid valve, the second operating parameter is the second voltage applied to the two-position three-way solenoid valve, and the third operating parameter is the third voltage applied to the two-position three-way solenoid valve as an example, the two-position three-way solenoid valve includes a solenoid valve and an electromagnet. When the first voltage is applied to the electromagnet, the left path of the solenoid valve is connected, and at this time, the exhaust end of the compressor 1 is connected to the exhaust pipe 9; when the second voltage is applied to the electromagnet, the left and right paths of the solenoid valve are both connected, and at this time, the exhaust end of the compressor 1 is connected to the exhaust pipe 9, and the exhaust end of the compressor 1 is connected to the condensation pipe 3; when the third voltage is applied to the electromagnet, the right path of the solenoid valve is connected, and at this time, the exhaust end of the compressor 1 is connected to the condensation pipe 3.

[0089] Among them, the first voltage, the second voltage and the third voltage are different voltages. The first voltage can be the rated voltage, the second voltage can be half of the rated voltage, and the third voltage can be 0V. Of course, the present disclosure does not limit the specific values ​​of the first voltage, the second voltage and the third voltage. The first voltage, the second voltage and the third voltage can also be three other different voltages.

[0090] See also Figure 4 As shown, taking the conduction module 2 as an electric three-way valve, the first operating parameter is the first angle of the electric valve, the second operating parameter is the second angle of the electric valve, and the third operating parameter is the third angle of the electric valve as an example, the electric three-way valve includes an electric valve and a motor. When the motor drives the electric valve to rotate to the first angle, the left path of the electric valve is connected, and at this time, the exhaust end of the compressor 1 is connected to the exhaust pipe 9; when the motor drives the electric valve to rotate to the second angle, the left and right paths of the electric valve are both connected, and at this time, the exhaust end of the compressor 1 is connected to the exhaust pipe 9, and the exhaust end of the compressor 1 is connected to the condensation pipe 3; when the motor drives the electric valve to rotate to the third angle, the right path of the electric valve is connected, and at this time, the exhaust end of the compressor 1 is connected to the condensation pipe 3.

[0091] Among them, the first angle, the second angle and the third angle can be different angles, the first angle can be 0°, the second angle can be 90°, and the third angle can be 180°. Of course, the present disclosure does not limit the specific values ​​of the first angle, the second angle and the third angle, and the first angle, the second angle and the third angle can also be three other different voltages.

[0092] Through the above technical scheme, different operating parameters are operated by the conduction module 2, so that the leak line 9, the compressor 1 and the condensation line 3 in the refrigeration device are in different conduction states, for example, in a first state where the exhaust end of the compressor 1 is connected to the leak line 9, in a second state where the exhaust end of the compressor 1, the leak line 9 and the condensation line 3 are all connected, and in a third state where the exhaust end of the compressor 1 is connected to the condensation line 3, etc., thereby controlling the gas refrigerant discharged from the exhaust end of the compressor 1 to flow into the leak line and / or the condensation line 3, thereby releasing the pressure on the exhaust end of the compressor 1 and ensuring the normal operation of the refrigeration of the entire refrigeration device.

[0093] Figure 5 : is a flowchart of a control method for a refrigeration device proposed in the present disclosure. The control method for a refrigeration device is applied to the above-mentioned refrigeration device, and comprises the following steps:

[0094] In step S10, before the compressor is started, the conducting module is controlled to conduct the exhaust end of the compressor with the exhaust pipe.

[0095] Optionally, at a first time point before the compressor is started, the conducting module may be controlled to conduct the exhaust end of the compressor with the air leakage pipeline.

[0096] There is a first preset time length between the first time point and the second time point when the compressor is started.

[0097] See also Figure 6 As shown, Figure 6 The horizontal axis is time, and the vertical axis is the first flow rate ratio of the air leakage pipeline. Taking the first time point as t1, the second time point as t2, and the first preset time length as T1 as an example, the conduction module can be controlled to conduct the exhaust end of the compressor and the air leakage pipeline at the first time point t1 before the second time point t2 when the compressor is started, which is the first preset time length T1.

[0098] For example, if the conduction module is a two-position three-way solenoid valve, a first voltage may be applied to the two-position three-way solenoid valve at a first time point t1 to conduct the exhaust end of the compressor and the exhaust pipe. For another example, if the conduction module is an electric three-way valve, the electric three-way valve is controlled to rotate to a first angle at the first time point t1 to conduct the exhaust end of the compressor and the exhaust pipe. The first preset time length may be 2S to 3S.

[0099] It is understandable that the bleed pipe has a first flow ratio, which refers to the ratio of the flow of the refrigerant in the bleed pipe to the total flow output of the exhaust end of the compressor. In the process of connecting the exhaust end of the compressor to the bleed pipe, the first flow ratio in the bleed pipe does not reach 100% immediately, but will gradually increase to 100% as the valve opening of the conduction module to the bleed pipe gradually increases. Therefore, Figure 6 In the figure, starting from the first time point t1 when the conduction module conducts the exhaust end of the compressor and the bleed pipe, the first flow rate ratio in the bleed pipe will gradually increase until 100%. When the first flow rate ratio reaches 100%, it means that the refrigerant discharged from the exhaust end of the compressor will all enter the bleed pipe.

[0100] When designing the conduction time point of the exhaust end of the compressor and the air leakage pipeline, the conduction time point can be set after the compressor stops working. However, setting the conduction time point after the compressor stops working will cause the refrigeration effect of the freezer to deteriorate. The reason is that there is an air cooling principle in the field of refrigerators. The air cooling principle is to input the cold air in the evaporation chamber into the freezer. If the temperature of the evaporation chamber is high, the temperature of the cold air input to the freezer will be high, resulting in the freezer being difficult to refrigerate. If the exhaust end of the compressor and the air leakage pipeline are immediately connected after the compressor stops working, the high-temperature and high-pressure gas output from the exhaust end of the compressor will be immediately released to the suction end of the compressor through the air leakage pipeline. The suction end of the compressor is connected to the evaporation chamber, so the high-temperature and high-pressure gas will also be immediately released to the evaporation chamber, resulting in a higher temperature in the evaporation chamber. After the temperature of the evaporation chamber increases, the temperature of the evaporation chamber delivered to the freezer will also be high, resulting in the freezer being difficult to refrigerate.

[0101] Through the above technical scheme, the exhaust end of the compressor and the air leakage pipe are connected at a first time point at an interval of a first preset time before the compressor is started. For example, the exhaust end of the compressor and the air leakage pipe are connected at a first time point 2S to 3S before the compressor is started. In this way, even if the high-temperature and high-pressure gas output from the exhaust end of the compressor is discharged to the suction end of the compressor through the air leakage pipe, and then discharged to the freezer compartment, the compressor will start immediately after 2 to 3S to provide refrigeration for the freezer compartment. When the temperature of the freezer compartment has not yet risen, the compressor has started to restart the refrigeration, which will not affect the temperature of the freezer compartment, thereby ensuring the refrigeration effect of the freezer compartment.

[0102] Figure 7 is an exemplary embodiment of the present disclosure, which is used to explain that after the first flow ratio of the leak line reaches a preset threshold, the state is maintained for a second preset time to make the compressor easier to start, and includes the following steps:

[0103] In step S20, when the air leakage line reaches the first state, the first state is controlled to be maintained for a second preset time period.

[0104] The first state includes that a first flow rate ratio of the air leakage pipeline reaches a preset threshold value, and a third time point when the air leakage pipeline reaches the first state is between the first time point and the second time point.

[0105] The third time point is the time point when the first flow rate proportion of the leak pipeline reaches a preset threshold value, which may be 100%, or may refer to the time point when all the gas refrigerant discharged from the exhaust end of the compressor is transmitted to the leak pipeline.

[0106] See also Figure 6 As shown, taking the second preset time length T2 as an example, after the first flow ratio of the air leakage pipeline reaches the first state of the preset threshold at the third time point t3, the air leakage pipeline can be controlled to maintain the first state for the second preset time length T2.

[0107] In step S30, when the first state is maintained for the second preset time period, the compressor is controlled to start.

[0108] After the first state is maintained for a second preset time, the compressor can be controlled to start. At this time, the time point when the compressor starts is Figure 6 The second time point t2 in the third time point. There is a second preset time length between the third time point and the second time point, and the second preset time length is smaller than the first preset time length between the first time point and the second time point.

[0109] Due to the limitation of the valve opening ratio of the conduction module, in the process of the valve opening of the conduction module opening from 0% to 100%, the first flow ratio of the bleed pipe will increase from 0% to the preset threshold value of 100%. In this process, the high-temperature and high-pressure gas refrigerant in the compressor may not be completely discharged into the bleed pipe, and some high-temperature and high-pressure gas refrigerant may remain.

[0110] Through the above technical solution, after the first flow rate of the leak line reaches the first state of 100% of the preset threshold value, the leak line will be controlled to maintain the first state for a second preset time, for example, 2S, so that when the valve opening of the conduction module reaches 100%, the compressor continues to discharge the high-temperature and high-pressure gas refrigerant to the leak line for the second preset time, so as to ensure that the high-temperature and high-pressure gas refrigerant on the exhaust end side of the compressor can be discharged to the intake end as much as possible before the compressor starts, so as to further reduce the pressure difference between the exhaust end and the intake end of the compressor, thereby further improving the possibility of successful startup of the compressor.

[0111] Figure 8 An exemplary embodiment of the present disclosure is shown, which is used to explain the flow chart of steps in the compressor startup process, including the following steps:

[0112] In step S40, after the compressor is started, the first state is controlled to be maintained for a third preset time period.

[0113] Optionally, after the second time point when the compressor is started, the first flow rate ratio of the air leakage pipeline can be controlled to continue to be maintained at the first state of 100% for a third preset time. The third preset time can be Figure 6 The second time point may also be the time point when the compressor is ready to start.

[0114] Through the above technical solution, after the second time point when the compressor is started, the first flow ratio of the air leakage pipeline can continue to be controlled to maintain the third preset time length in the first state to continuously discharge the pressure at the exhaust end of the compressor, so as to make the starting process of the compressor after the second time point easier and reduce the starting failure rate of the compressor.

[0115] Fig. 9 An exemplary embodiment of the present disclosure is shown, which is used to explain the flow chart of steps after the compressor is successfully started, including the following steps:

[0116] In step S50, when the first state is maintained for the third preset time, the conduction module is controlled to conduct the exhaust end of the compressor and the air leakage pipeline, and the conduction module is controlled to conduct the exhaust pipe of the compressor and the condensation pipeline.

[0117] After the second time point when the compressor is started and after the third preset time has passed, it indicates that the compressor has been successfully started. At this time, the conduction module can be controlled to conduct the exhaust end of the compressor and the air leakage pipeline while also conducting the exhaust pipe and the condensation pipeline of the compressor.

[0118] For example, if the conduction module is a two-position three-way solenoid valve, when the leak pipeline maintains the first state for a third preset time, a second voltage can be applied to the two-position three-way solenoid valve to conduct the exhaust end of the compressor with the leak pipeline, and at the same time conduct the exhaust end of the compressor with the condensation pipeline. For another example, if the conduction module is an electric three-way valve, when the leak pipeline maintains the first state for a third preset time, the electric three-way valve can be controlled to rotate to a second angle to conduct the exhaust end of the compressor with the leak pipeline, and at the same time conduct the exhaust end of the compressor with the condensation pipeline.

[0119] It is understandable that after the compressor is successfully started, the compressor needs to provide high-temperature and high-pressure gas refrigerant to the entire refrigeration device. Therefore, the exhaust end of the compressor needs to be connected to the condensation pipeline to transmit the high-temperature and high-pressure gas refrigerant generated at the exhaust end of the compressor to the condensation pipeline.

[0120] Optionally, in the process of controlling the conduction module to conduct the exhaust end of the compressor and the bleed pipe, and controlling the conduction module to conduct the exhaust pipe of the compressor and the condensation pipe, the valve opening of the conduction module can be controlled to control the first flow ratio of the bleed pipe to decrease, and the second flow ratio of the condensation pipe to increase. The second flow ratio indicates the ratio of the flow in the condensation pipe to the total flow output from the exhaust end of the compressor.

[0121] See also Figure 1 As shown, part of the gas refrigerant discharged from the exhaust end of the compressor will enter the leak line, and the other part will enter the condensation line. Therefore, the total flow rate at the exhaust end of the compressor is equal to the sum of the coolant flow rate of the leak line and the coolant flow rate of the condensation line. The corresponding sum of the first flow rate proportion of the leak line and the second flow rate proportion of the condensation line is 1.

[0122] It is understandable that during the operation of the compressor after startup, the compressor does not provide refrigeration with a constant refrigerant flow rate, but rather varies according to the type of the compressor.

[0123] For example, for a first compressor whose cooling speed is slow at first and then fast, the flow rate of the gas refrigerant discharged from the exhaust end of the first compressor is slow at first and then fast. The first compressor is a compressor whose Coefficient of Performance (COP) is less than a first preset value (e.g., 1.6).

[0124] For example, for a second compressor whose cooling speed increases slowly at first and then increases slowly after reaching a point, the flow rate of the gas refrigerant discharged from the exhaust end of the second compressor is fast at first and then slow. The second compressor has a refrigeration coefficient greater than a first preset value (for example, 1.6) and less than a second preset value (for example, 2.0).

[0125] For example, for the third compressor whose refrigeration speed gradually slows down, the flow rate of the gas refrigerant discharged from the exhaust end of the third compressor will gradually slow down. The third compressor is a compressor with a refrigeration coefficient greater than a second preset value (for example, 2.0).

[0126] Then, in order to adapt to the flow curves output by different types of compressors, the valve opening of the conduction module can be controlled so that the falling curve of the first flow ratio in the leaking pipeline matches the operating curve of the compressor, for example, the falling speed trend of the first flow ratio in the leaking pipeline matches the running speed trend of the compressor. In the process of the valve opening of the conduction module changing from small to large, the first flow ratio of the leaking pipeline gradually increases, and the second flow ratio of the condensing pipeline gradually decreases; in the process of the valve opening of the conduction module changing from large to small, the first flow ratio of the leaking pipeline gradually decreases, and the second flow ratio of the condensing pipeline gradually increases.

[0127] For example, see Fig.10 As shown, for the first compressor whose cooling speed is slow at first and then fast, the valve opening can be controlled to decrease slowly at first and then quickly in the process that the valve opening of the conduction module decreases from 100% to 0%. Then, in the process that the first flow proportion in the corresponding exhaust pipe decreases from 100% to 0%, it also decreases according to the trend of first slowly decreasing and then quickly decreasing. In this way, the refrigerant flow transmitted by the first compressor to the condensing pipe also increases slowly at first and then quickly increases, so that the flow rate of the gas refrigerant transmitted by the first compressor to the refrigeration circuit is transmitted with a trend of first slow cooling and then quickly cooling, thereby achieving a refrigeration effect of first slow cooling and then fast cooling.

[0128] For example, see Fig.11 As shown, for the second compressor whose cooling speed is fast at first and then slow, the valve opening speed can be controlled to be fast at first and then slow in the process of the valve opening of the conduction module decreasing from 100% to 0%. Then, in the process of the first flow proportion in the corresponding exhaust pipe decreasing from 100% to 0%, it also decreases according to the trend of first fast and then slow. In this way, the refrigerant flow transmitted by the first compressor to the condensing pipe also increases rapidly at first and then slowly, so that the flow of the gas refrigerant transmitted by the second compressor to the refrigeration circuit is transmitted with a trend of first fast and then slow, achieving the refrigeration effect of first fast cooling and then decreasing the refrigeration speed.

[0129] For example, see Fig.12 As shown, for the third compressor whose refrigeration speed is continuously slowing down, the speed of controlling the valve opening to be gradually slowed down can be used in the process that the valve opening of the conduction module is reduced from 100% to 0%. Then, in the process that the first flow proportion in the corresponding air leakage pipeline decreases from 100% to 0%, it also decreases in a gradually slowing trend. In this way, the refrigerant flow rate transmitted by the first compressor to the condensing pipeline is also gradually slowed down, so that the flow rate of the gas refrigerant transmitted by the third compressor to the refrigeration circuit is transmitted in a gradually slowing trend, thereby achieving a refrigeration effect with a gradually decreasing refrigeration speed.

[0130] Of course, the cooling effects of the above three compressors are just some examples. When controlling the valve opening of the conduction module, the first flow ratio of the bleed pipe and the second flow ratio of the condensing pipe, it is also possible to execute according to curves that match the operating curves of other compressors to achieve the cooling effects that other compressors want to achieve.

[0131] Through the above technical solution, by controlling the valve opening of the conduction module, the first flow ratio of the vent pipe can be reduced with different downward trends, and the second flow ratio of the condensation pipe can be increased with different upward trends, thereby achieving the refrigeration effect required by different compressors.
