Description

Technical Field

[0002] In the related art, when an independent micro-compressor is used to refrigerate an in-vehicle refrigerator, the refrigeration power is small and the refrigeration speed is slow. When a traditional air-conditioning system is used to refrigerate an in-vehicle refrigerator, since the refrigeration core component is a mechanical compressor, the power system output of the whole vehicle will be consumed when the refrigerator is rapidly refrigerated, affecting the user driving experience; in addition, if the whole vehicle air-conditioning system is not turned on and the air-conditioning system is only turned on due to the refrigeration of the in-vehicle refrigerator, it will cause waste of the energy consumption of the whole vehicle and generate high noise.

[0069] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. Below, reference is made to Figures 1-14 Describe the thermal management system 100 according to the first aspect embodiment of the embodiments of the present invention, including an air-conditioning module 10 and a refrigerator module 20.

[0070] Specifically, as Figures 1-12 shown, the air-conditioning module 10 includes an outside-vehicle heat exchanger 12 and a compressor 13. The first end of the outside-vehicle heat exchanger 12 is selectively connected to the inlet and outlet of the compressor 13; the refrigerator module 20 includes a refrigerator heat exchanger 21. The first end of the refrigerator heat exchanger 21 is selectively connected to the second end of the outside-vehicle heat exchanger 12, and the second end of the refrigerator heat exchanger 21 is selectively connected to the outlet of the compressor 13.

[0071] In this embodiment, the refrigerator module 20 is connected to the thermal management system 100 of the vehicle air conditioner. That is, on the basis that the refrigerator module 20 and the air-conditioning module 10 share the compressor 13, the refrigerator module 20 can independently achieve heating and cooling, and the refrigerator module 20 can also use the thermal management system 100 to achieve heating and cooling inside the refrigerator module 20. For example, when the refrigerator is heating alone, the refrigerant in the thermal management system flows from the outlet of the compressor 13 to the refrigerator heat exchanger 21 and flows through the outside-vehicle heat exchanger 12 to the inlet of the compressor 13 to achieve heating of the refrigerator. When the refrigerator is cooling alone, the refrigerant in the thermal management system flows from the outlet of the compressor 13 to the outside-vehicle heat exchanger 12, flows through the refrigerator heat exchanger 21 to the inlet of the compressor 13 to achieve cooling of the refrigerator.

[0072] According to the thermal management system 100 of the embodiments of the present invention, by connecting the refrigerator module 20 to the air-conditioning module 10, it is convenient to use the heating capacity and cooling capacity of the air-conditioning module 10 to achieve heating and cooling of the refrigerator module 20. At the same time, since the refrigerator heat exchanger 21 and the compressor 13 can be directly connected, the refrigerator module 20 can independently achieve heating and cooling, improving the user experience and effectively reducing energy consumption. And since the compressor of the refrigerator module 20 is cancelled, the structure of the entire thermal management system 100 is optimized, reducing the occupation of the vehicle interior space by the thermal management system 100 and improving the efficiency of the thermal management system 100.

[0073] In some embodiments, the refrigerator module 20 further includes: a throttle valve, the first end of the throttle valve is selectively connected to the second end of the external heat exchanger 12 of the vehicle, and the second end of the throttle valve is connected to the first end of the refrigerator heat exchanger 21. For example, in the heating mode of the refrigerator, the throttle valve can throttle the refrigerant flowing out of the refrigerator heat exchanger 21, or in the refrigeration mode of the refrigerator, the throttle valve can throttle the refrigerant flowing into the refrigerator heat exchanger 21. The throttle valve can adjust the amount of refrigerant flowing in and out of the refrigerator heat exchanger 21, so as to adjust the refrigerant flow rate in the thermal management system 100 to adapt to different working conditions.

[0074] In some embodiments, such as Figures 1-6 As shown, the air-conditioning module 10 includes: an in-vehicle heat exchanger 11, and the in-vehicle heat exchanger 11 includes: an in-vehicle evaporator 111 and an in-vehicle condenser 112. The first end of the in-vehicle evaporator 111 is selectively connected to the second end of the external heat exchanger 12 of the vehicle and the first end of the refrigerator heat exchanger 21. The second end of the in-vehicle evaporator 111 is selectively connected to the inlet of the compressor 13. That is, the first end of the in-vehicle evaporator 111 can be selectively connected to the second end of the external heat exchanger 12 of the vehicle or the first end of the refrigerator heat exchanger 21 according to requirements, so as to ensure the normal flow of the refrigerant in the thermal management system 100 under different working conditions.

[0075] The first end of the in-vehicle condenser 112 is connected to the outlet of the compressor 13. The second end of the in-vehicle condenser 112 is selectively connected to the first end of the external heat exchanger 12 of the vehicle and the second end of the in-vehicle evaporator 111. The first end of the external heat exchanger 12 of the vehicle is selectively connected to the second end of the in-vehicle condenser 112 and the inlet of the compressor 13. The second end of the external heat exchanger 12 of the vehicle is selectively connected to the first end of the refrigerator heat exchanger 21 and the second end of the in-vehicle evaporator 111. The second end of the refrigerator heat exchanger 21 is connected to the inlet of the compressor 13. That is, the second end of the in-vehicle condenser 112 is connected to the first end of the external heat exchanger 12 of the vehicle or the second end of the in-vehicle evaporator 111. The first end of the external heat exchanger 12 of the vehicle can be connected to the second end of the in-vehicle condenser 112 or the inlet of the compressor 13. The second end of the external heat exchanger 12 of the vehicle can be connected to the first end of the refrigerator heat exchanger 21 or the second end of the in-vehicle evaporator 111.

[0076] In some embodiments, such as Figure 1As shown, the air conditioning module 10 further includes: a liquid receiver 14. The first end of the liquid receiver 14 is selectively connected to the second end of the external heat exchanger 12 and the second end of the internal evaporator 111. The second end of the liquid receiver 14 is selectively connected to the first end of the refrigerator heat exchanger 21, the first end of the internal evaporator 111, and the second end of the external heat exchanger 12. That is, the refrigerant flowing through the liquid receiver 14 from the external heat exchanger 12 can flow to at least one of the refrigerator heat exchanger 21, the internal evaporator 111, and the external heat exchanger 12. The liquid receiver 14 can be used to store a certain amount of refrigerant to ensure the amount of refrigerant required for the refrigerant cycle in the thermal management system 100 and ensure the refrigeration and heating capabilities of the thermal management system 100.

[0077] Further, referring to Figures 1-6 , the air conditioning module 10 further includes: a first four-way valve 30. The first four-way valve 30 includes a first interface 31, a second interface 32, a third interface 33, and a fourth interface 34. The first interface 31, the second interface 32, the third interface 33, and the fourth interface 34 are arranged at intervals along the circumferential direction of the first four-way valve 30, and each interface is in communication with at least two adjacent interfaces.

[0078] Wherein, the first end of the first interface 31 is connected to the second end of the internal condenser 112, and the second end of the first interface 31 is selectively connected to the second end of the second interface 32 and the second end of the fourth interface 34;

[0079] The first end of the second interface 32 is connected to the first end of the external heat exchanger 12, and the second end of the second interface 32 is selectively connected to the second end of the first interface 31 and the second end of the third interface 33;

[0080] The first end of the third interface 33 is selectively connected to the second end of the refrigerator heat exchanger 21 and the inlet of the compressor 13, and the second end of the third interface 33 is selectively connected to the second end of the second interface 32 and the second end of the fourth interface 34;

[0081] The first end of the fourth interface 34 is connected to the second end of the internal evaporator 111, and the second end of the fourth interface 34 is selectively connected to the second end of the first interface 31 and the second end of the third interface 33.

[0082] In some embodiments, such as Figures 1-6As shown in the figure, the air conditioning module 10 further includes: a first throttle valve 51, a second throttle valve 52, and a third throttle valve 54. The first end of the first throttle valve 51 is connected to the second end of the in-vehicle condenser 112, and the second end of the first throttle valve 51 is connected to the first interface 31 of the first four-way valve 30; the first end of the second throttle valve 52 is selectively connected to the first end of the refrigerator heat exchanger 21, the second end of the out-of-vehicle heat exchanger 12, and the first end of the in-vehicle evaporator 111, and the second end of the second throttle valve 52 is selectively connected to the second end of the out-of-vehicle heat exchanger 12 and the first end of the in-vehicle condenser 112; the first end of the third throttle valve 54 is connected to the outlet of the compressor 13, and the second end of the third throttle valve 54 is connected to the second end of the refrigerator heat exchanger 21. The refrigerator module 20 further includes a fourth throttle valve 53. The first end of the fourth throttle valve 53 is selectively connected to the second end of the out-of-vehicle heat exchanger 12 and the first end of the second throttle valve 52, and the second end of the fourth throttle valve 53 is connected to the first end of the refrigerator heat exchanger 21.

[0083] Optionally, the first throttle valve 51, the fourth throttle valve 53, and the third throttle valve 54 respectively have a first working state and a second working state, and the flow rate in the second working state of the first throttle valve 51, the fourth throttle valve 53, and the third throttle valve 54 is greater than the flow rate in the first working state.

[0084] That is, when the refrigerator module 20 or the air conditioning module 10 is normally heating or cooling, the first throttle valve 51, the fourth throttle valve 53, and the third throttle valve 54 are in the first working state. When, for example, the refrigerating capacity inside the refrigerator fails to reach the preset value and the compressor 13 is not in the operating state, the opening degree of the first throttle valve 51 can be adjusted. At this time, the first throttle valve 51 is in the second working state, and the flow rate of the first throttle valve 51 in the second working state is greater than the flow rate of the first throttle valve 51 in the first working state, that is, the amount of refrigerant flowing through the first throttle valve 51 at this time is increased to further reduce the temperature of the refrigerator module 20.

[0085] Among them, the throttle valves used in this embodiment all have a first working state and a second working state. The first working state is the throttling state, and the second working state is the fully open state. That is, in the second working state, the throttle valve does not have a throttling effect, and at this time, the throttle valve acts as a passage.

[0086] In some embodiments, such as Figure 1As shown, the air conditioning module 10 further includes: a first on-off valve 55, a first check valve 56, and a second check valve 57. The first end of the first on-off valve 55 is connected to the second end of the refrigerator heat exchanger 21, and the second end of the first on-off valve 55 is connected to the inlet of the compressor 13. The first end of the first check valve 56 is connected to the second end of the outside vehicle heat exchanger 12, and the second end of the first check valve 56 is selectively connected to the first end of the refrigerator heat exchanger 21 and the first end of the in-vehicle evaporator 111. The first check valve 56 is used to flow the refrigerant from the outside vehicle heat exchanger 12 through the accumulator 14 to the refrigerator heat exchanger 21 or the in-vehicle evaporator 111. The first end of the second check valve 57 is connected to the second end of the second throttle valve 52, and the second end of the second check valve 57 is connected to the second end of the outside vehicle heat exchanger 12. The second check valve 57 is used to flow the refrigerant from the second throttle valve 52 to the outside vehicle heat exchanger 12.

[0087] In some embodiments, as Figure 1 shown, the thermal management system 100 has a first separate refrigeration state for the refrigerator. When the thermal management system 100 is in the first separate refrigeration state for the refrigerator, the first throttle valve 51, the first check valve 56, the fourth throttle valve 53, and the first on-off valve 55 are opened, and the second throttle valve 52, the third throttle valve 54, and the second check valve 57 are closed. Among them, the first throttle valve 51 is in the first working state.

[0088] When the thermal management system 100 is in the first separate refrigeration state for the refrigerator, the compressor 13 sucks in the low-temperature and low-pressure refrigerant gas, which is compressed by the compressor 13 to form a high-temperature and high-pressure refrigerant gas and flows to the in-vehicle condenser 112. Then it sequentially passes through the first throttle valve 51 and the first interface 31 of the first four-way valve 30 and flows out of the first four-way valve 30 from the second interface 32, and then flows to the outside vehicle heat exchanger 12 and the accumulator 14 and then flows to the fourth throttle valve 53 for throttling. After evaporating and absorbing heat in the refrigerator heat exchanger 21, it returns to the compressor 13 through the first on-off valve 55 to form a cycle.

[0089] In some embodiments, as Figure 1 and Figure 14As shown, the thermal management system 100 has the first refrigerator cooling independently and the compressor 13 is not in the operating state. When the thermal management system 100 is in the state of the first refrigerator cooling independently and the compressor 13 is not in the operating state, the first throttle valve 51 is in the second working state. For example, when the temperature of the refrigerator module 20 does not reach the preset value, the first throttle valve 51 is in the second working state, and after the fourth throttle valve 53 is in the first working state and requests the compressor 13, at this time, the compressor 13 operates at the lowest speed as the starting control stage, and calculates the target suction pressure value corresponding to the set temperature T0 of the refrigerator and the required target evaporation temperature. The speed of the compressor 13 is adjusted by the difference between the suction pressure and the target suction pressure. Among them, the fourth throttle valve 53 maintains a fixed opening in the starting control stage, and in the operating control stage, the superheat at the outlet of the target refrigerator is controlled at 3-5°C through PID control (proportional-integral-derivative control), so as to realize the single-refrigerator cooling requirement of the refrigerator module 20.

[0090] In some embodiments, such as Figure 2 As shown, the thermal management system 100 has the state of the first refrigerator heating independently. When the thermal management system 100 is in the state of the first refrigerator heating independently, the third throttle valve 54, the fourth throttle valve 53 and the second throttle valve 52 are opened, the first on-off valve 55 is closed, and the second interface 32 and the third interface 33 of the first four-way valve 30 are connected. Among them, the third throttle valve 54 is in the first working state.

[0091] When the thermal management system 100 is in the state of the first refrigerator heating independently, the compressor 13 sucks in the refrigerant gas at low temperature and low pressure, compresses it to form the refrigerant gas at high temperature and high pressure, flows through the third throttle valve 54 to condense and release heat in the refrigerator heat exchanger 21, is throttled once by the fourth throttle valve 53, then flows through the second throttle valve 52 and then evaporates and absorbs heat in the vehicle exterior heat exchanger 12, and then enters the first four-way valve 30 through the second interface 32 of the first four-way valve 30 and returns to the compressor 13 from the third interface 33 to complete a cycle.

[0092] In some embodiments, such as Figure 2 and Figure 13 As shown, the thermal management system 100 has the first refrigerator heating independently and the compressor 13 is not in the operating state. When the thermal management system 100 is in the state of the first refrigerator heating independently and the compressor 13 is not in the operating state, the third throttle valve 54 is in the second working state.

[0093] For example, when the refrigerator module 20 requests heating, that is, when the heating capacity inside the refrigerator module 20 cannot meet the set requirements and the compressor 13 is not in the operating state, at this time, the first throttle valve 51 and the first on-off valve 55 are turned off, the third throttle valve 54 is in the second working state. After requesting the compressor 13 to start at the initial speed and running for N4 seconds, by comparing the set temperature T0, calculating the corresponding target condensing pressure, and then controlling the fourth throttle valve 53 through the pressure difference and the pressure difference change rate, different target values of the condensing pressure can be achieved. For the second throttle valve 52, it mainly serves as the evaporation side, and superheat control can be adopted.

[0094] In some embodiments, as Figures 1-6 shown, the air-conditioning module 10 includes: a third check valve 58 and a fourth check valve 59. The first end of the third check valve 58 is connected to the second end of the second throttle valve 52, the second end of the third check valve 58 is connected to the first end of the in-vehicle evaporator 111, and the third check valve 58 is used to flow the refrigerant from the second throttle valve 52 to the in-vehicle evaporator 111; the first end of the fourth check valve 59 is connected to the first end of the in-vehicle evaporator 111, the second end of the fourth check valve 59 is connected to the first end of the second throttle valve 52, and the fourth check valve 59 is used to flow the refrigerant from the in-vehicle evaporator 111 to the fourth check valve 59.

[0095] In some embodiments, as Figure 3 shown, the thermal management system 100 has a first synchronous refrigeration state of the refrigerator and the air conditioner. When the thermal management system 100 is in the first synchronous refrigeration state of the refrigerator and the air conditioner, the first check valve 56, the fourth throttle valve 53, the first on-off valve 55, and the second throttle valve 52 are opened, the second check valve 57 and the third throttle valve 54 are closed, the first interface 31 and the second interface 32 are communicated, and the third interface 33 and the fourth interface 34 are communicated.

[0096] In this embodiment, when the thermal management system 100 is in the first synchronous refrigeration state of the refrigerator and the air conditioner, the compressor 13 sucks in the refrigerant gas at low temperature and low pressure, compresses it to form the refrigerant gas at high temperature and high pressure. The refrigerant gas at high temperature and high pressure flows through the in-vehicle condenser 112, the first throttle valve 51, the first interface 31 of the first four-way valve 30, and flows out from the second interface 32 to the out-of-vehicle heat exchanger 12 for condensation and heat release. Then, the high-pressure liquid refrigerant flows through the first check valve 56 and the accumulator 14 to the fourth throttle valve 53 for throttling and then evaporates and absorbs heat in the refrigerator heat exchanger 21, and then returns to the compressor 13 after passing through the first on-off valve 55, completing the refrigerator-side cycle.

[0097] Among them, after the refrigerant flows out of the liquid receiver 14, another path is throttled by the second throttle valve 52, then passes through the third check valve 58 and evaporates and absorbs heat in the in-vehicle evaporator 111 to complete the air-conditioning side cycle. During the refrigeration process of the air-conditioning module 10, the refrigerator module 20 only needs to open the corresponding valve to request cooling. At this time, the fourth throttle valve 53 is opened to the initial opening and lasts for a period of time, and then the opening of the fourth throttle valve 53 is adjusted according to PID, such as adjusting to the second working state, and the superheat at the refrigerator outlet is adjusted to 3-5°C.

[0098] In some embodiments, as Figure 4 shown, the thermal management system 100 has the state of the first refrigerator heating and the air conditioner cooling; when the thermal management system 100 is in the state of the first refrigerator heating and the air conditioner cooling, the third throttle valve 54, the fourth throttle valve 53, the second throttle valve 52, the first throttle valve 51, the first check valve 56, and the third check valve 58 are opened, the first on-off valve 55, the second check valve 57, and the fourth check valve 59 are closed, the first interface 31 and the second interface 32 are connected, and the third interface 33 and the fourth interface 34 are connected.

[0099] In this embodiment, the thermal management system 100 is in the state of the first refrigerator heating and the air conditioner cooling. The compressor 13 sucks in the refrigerant gas at low temperature and low pressure, compresses it to form the refrigerant gas at high temperature and high pressure, and the refrigerant gas at high temperature and high pressure forms two branches after leaving the compressor 13. One path flows through the third throttle valve 54 and condenses and releases heat in the refrigerator heat exchanger 21, and then passes through the fourth throttle valve 53 and converges with another path of refrigerant before reaching the second throttle valve 52. At this time, the fourth throttle valve 53 is in the second working state. The other path flows through the in-vehicle condenser 112, the first throttle valve 51, the first four-way valve 30 to the out-of-vehicle heat exchanger 12 to condense and release heat, and then the high-pressure liquid refrigerant passes through the first check valve 56, the liquid receiver 14 and converges with the path flowing through the refrigerator heat exchanger 21 before reaching the throttle valve. After the two paths of refrigerant are throttled and depressurized by the second throttle valve 52, the two-phase refrigerant passes through the third check valve 58 and then evaporates and absorbs heat in the in-vehicle evaporator 111, enters the first four-way valve 30 through the fourth interface 34 of the first four-way valve 30, and returns to the compressor 13 from the third interface 33 to complete a cycle.

[0100] When the refrigerator requests heating, the first on-off valve 55 is closed, and the fourth throttle valve 53 is in the second working state. At this time, the thermal management system 100 adjusts the refrigerator condensation pressure through the third throttle valve 54, thereby achieving the effect of different heating temperatures of the refrigerator.

[0101] In some embodiments, as Figure 5As shown, the thermal management system 100 has a state where the first refrigerator and the air conditioner are heating synchronously. When the thermal management system 100 is in the state where the first refrigerator and the air conditioner are heating synchronously, the first throttle valve 51, the fourth check valve 59, the second throttle valve 52, the second check valve 57, the third throttle valve 54, and the fourth throttle valve 53 are opened, and the first on-off valve 55, the third check valve 58, and the first check valve 56 are shut off. The first interface 31 and the fourth interface 34 are communicated, and the second interface 32 and the third interface 33 are communicated.

[0102] In this embodiment, the compressor 13 sucks in the refrigerant gas at low temperature and low pressure. After compression, the high-temperature and high-pressure refrigerant gas is discharged from the compressor 13 and is divided into two paths. One path flows through the in-vehicle condenser 112 to condense and release heat, and is throttled once by the first throttle valve 51. The refrigerant at the intermediate pressure after the first throttling flows into the first four-way valve 30 from the first interface 31, and goes to the in-vehicle evaporator 111 from the fourth interface 34 for secondary condensation and heat release. Then, the medium-pressure liquid refrigerant passes through the fourth check valve 59 and the accumulator 14 and converges with the other refrigerant path in front of the second throttle valve 52. The other path flows through the third throttle valve 54 to the refrigerator heat exchanger 21 to condense and release heat, and then passes through the fourth throttle valve 53 which is fully opened, that is, the fourth throttle valve 53 is in the second working state at this time, and converges with the refrigerant path passing through the accumulator 14 in front of the second throttle valve 52. After the converged refrigerant is throttled and depressurized by the second throttle valve 52, the two-phase refrigerant passes through the second check valve 57 and then evaporates and absorbs heat in the out-of-vehicle heat exchanger 12, and then enters the first four-way valve 30 from the second interface of the first four-way valve 30 and returns to the compressor 13 from the third interface 33 to complete a cycle.

[0103] When the refrigerator requests heating, the first on-off valve 55 is shut off, and the fourth throttle valve 53 is in the second working state. At this time, the thermal management system 100 adjusts the refrigerator condensation pressure through the third throttle valve 54, thereby achieving the effect of different heating temperatures of the refrigerator.

[0104] In some embodiments, as Figure 6 shown, the thermal management system 100 has a state where the first refrigerator is refrigerating and the air conditioner is heating. When the thermal management system 100 is in the state where the first refrigerator is refrigerating and the air conditioner is heating, the first throttle valve 51, the fourth check valve 59, the fourth throttle valve 53, the second throttle valve 52, and the second check valve 57 are opened, and the third check valve 58, the first check valve 56, and the third throttle valve 54 are shut off. The first interface 31 and the fourth interface 34 are communicated, and the second interface 32 and the third interface 33 are communicated.

[0105] In this embodiment, the compressor 13 sucks in the refrigerant gas at low temperature and low pressure, compresses it to form a refrigerant gas at high temperature and high pressure, flows through the in-vehicle condenser 112 to release heat by condensation, undergoes a primary throttling through the first throttle valve 51, and the refrigerant at intermediate pressure after the primary throttling flows into the first four-way valve 30 and then to the in-vehicle evaporator 111 for secondary condensation and heat release. Then, the medium-pressure liquid refrigerant passes through the fourth check valve 59 and the accumulator 14. The refrigerant at the second end of the accumulator 14 is divided into two paths. One path flows to the fourth throttle valve 53 for throttling and then evaporates and absorbs heat in the refrigerator heat exchanger 21, and then returns to the compressor 13 after passing through the first on-off valve 55, completing the refrigerator-side cycle. The other path passes through the second throttle valve 52 for throttling, and the two-phase refrigerant passes through the second check valve 57 to the out-of-vehicle heat exchanger 12 to evaporate and absorb heat, and then enters the first four-way valve 30 through the second interface 32 of the first four-way valve 30 and returns to the compressor 13 from the third interface 33, completing the air-conditioning-side cycle.

[0106] During the heating process of the air-conditioning module 10, for the refrigerator module 20 to request cooling, only the corresponding valve needs to be opened. The first on-off valve 55 is opened, and the third throttle valve 54 is closed. At this time, the fourth throttle valve 53 is opened to the initial opening and lasts for a period of time, and then the opening of the fourth throttle valve 53 is adjusted according to PID to adjust the superheat at the refrigerator outlet to 3 - 5°C.

[0107] Specifically, combined with Figures 13-14 , the preset temperature of the refrigerator is T0, and the actual temperature of the refrigerator is T1. When the preset temperature T0 of the refrigerator is greater than the actual temperature T1 of the refrigerator and the temperature of the refrigerator module 20 has not reached the preset value, the refrigerator requests heating. If the heat pipe system is in the heating state at this time, the fourth throttle valve 53 is in the second working state, that is, fully open, the first on-off valve 55 is closed, and the third throttle valve 54 is opened to the initial opening, that is, the first working state. Calculate the target condensation pressure through T0, calculate the pressure difference of the refrigerator module 20. If it is less than 0.1 bar, the third throttle valve 54 maintains the current opening, that is, maintains the first working state, and cycles after a delay of N2 seconds. If the calculated pressure difference of the current refrigerator is greater than or equal to 0.1 bar, query the pressure difference value of the refrigerator in the previous cycle. At this time, judge whether the third throttle valve 54 is in the first working state. If so, maintain the current opening of the third throttle valve 54. If not, adjust the opening of the third throttle valve 54 according to the change value of the refrigerator pressure difference, and control the third throttle valve 54 to adjust between the first working state and the second working state.

[0108] When the heat management system 100 is in the refrigeration state when the refrigerator requests heating, the fourth throttle valve 53 is fully opened. The first on-off valve 55 is closed, the third throttle valve 54 is opened to the initial opening degree, and the target condensing pressure is calculated through T0. If the calculated pressure difference of the current refrigerator is less than 0.1 bar at this time, the third throttle valve 54 maintains the current opening degree. That is, in this process, the fourth throttle valve 53 is in the second working state, and the third throttle valve 54 is in the first working state. If the calculated pressure difference of the current refrigerator is greater than or equal to 0.1 bar, the system queries the pressure difference in the previous cycle, calculates the pressure difference change rate, and combines the opening degree of the third throttle valve 54. If the third throttle valve 54 is at the minimum opening degree, the current state is maintained. If it is not at the minimum opening degree, the third throttle valve 54 outputs the adjusted opening degree according to the change value of the pressure difference.

[0109] When the refrigerator requests heating and the compressor 13 starts, when the circulating time of the system is greater than 3 minutes, the system alarms to alert the staff to troubleshoot in time. If the circulating time is less than or equal to 3 minutes, it returns to the request for the refrigerator to heat.

[0110] When the refrigerator requests heating and the compressor 13 has not started, the first throttle valve 51 and the first on-off valve 55 are shut off, the third throttle valve 54 is fully opened and in the second working state, the second throttle valve 52 and the fourth throttle valve 53 are opened to the initial opening degree, that is, in the first working state, and the compressor 13 is requested to start. After a delay of N4 seconds, the second throttle valve 52 can be controlled by PID to adjust the suction superheat degree of the compressor 13 to 3 - 5 °C. And the target condensing pressure is calculated through T0. When the calculated pressure difference of the current refrigerator is less than 0.1 bar, the fourth throttle valve 53 maintains the current opening degree. If the calculated current pressure difference is greater than or equal to 0.1 bar, the system queries the pressure difference of the refrigerator in the previous cycle, obtains the pressure difference of the previous cycle, and then calculates the pressure difference change rate. If the opening degree of the fourth throttle valve 53 is the smallest at this time, the opening degree of the fourth throttle valve 53 is maintained. If it is not the smallest opening degree, the opening degree of the fourth throttle valve 53 is controlled by PID to output according to the change value of the pressure difference of the refrigerator. After the fourth throttle valve 53 maintains the current opening degree and works for N5 seconds, then judge the current pressure difference of the refrigerator for a new cycle.

[0111] If the preset temperature T0 of the refrigerator is less than or equal to the actual temperature of the refrigerator, the system requests the refrigerator to refrigerate. Subsequently, it is judged whether the system is in the heating state or the refrigeration state. Then the third throttle valve 54 is shut off, the first on-off valve 55 is opened, and the fourth throttle valve 53 is opened to the initial opening degree, that is, in the first working state and lasts for N3 seconds. Subsequently, the fourth throttle valve 53 is controlled by PID, and the superheat degree at the refrigerator outlet is adjusted to 3 - 5 °C.

[0112] If the refrigerator is requested to refrigerate and the thermal management system 100 is neither in the heating state nor in the cooling state, if the compressor 13 starts, it circulates for a certain period of time. For example, when the circulation time is greater than 3 minutes, it is considered a fault alarm. If the compressor 13 does not start, the second throttle valve 52 and the third throttle valve 54 are turned off, the first on-off valve 55 is opened, the first throttle valve 51 is fully opened, and the fourth throttle valve 53 is opened to the initial opening to request the start of the compressor 13. The fourth throttle valve 53 is controlled by PID to adjust the superheat at the refrigerator outlet to 3-5°C, calculate the target suction pressure of the refrigerator, and control the speed of the compressor 13 by PID to adjust the difference in the target suction pressure to be less than 0.5 bar.

[0113] In addition, the refrigerator also has a high-temperature one-key disinfection function.

[0114] In some embodiments, as Figures 7-12 shown, the air-conditioning module 10 further includes: a gas-liquid separator 15. The first end of the gas-liquid separator 15 is selectively connected to the second end of the refrigerator heat exchanger 21, the second end of the in-vehicle evaporator 111, and the second end of the out-of-vehicle heat exchanger 12. The second end of the gas-liquid separator 15 is connected to the inlet of the compressor 13. That is, the gas-liquid separator 15 is provided at the inlet of the compressor 13. After the refrigerant flows out of the outlet of the compressor 13, it passes through the gas-liquid separation of the gas-liquid separator 15, and the low-temperature and low-pressure gas enters the compressor 13, and the liquid can remain in the gas-liquid separator 15.

[0115] In some embodiments, in combination with Figures 7-12 , the air-conditioning module 10 includes: a second four-way valve 40. The second four-way valve 40 includes a fifth interface 41, a sixth interface 42, a seventh interface 43, and an eighth interface 44.

[0116] The first end of the fifth interface 41 is connected to the in-vehicle condenser 112, and the second end of the fifth interface 41 is selectively connected to the second end of the sixth interface 42 and the second end of the eighth interface 44;

[0117] The first end of the sixth interface 42 is connected to the second end of the out-of-vehicle heat exchanger 12, and the second end of the sixth interface 42 is selectively connected to the second end of the fifth interface 41 and the second end of the seventh interface 43;

[0118] The first end of the seventh interface 43 is connected to the inlet of the compressor 13, and the second end of the seventh interface 43 is selectively connected to the second end of the sixth interface 42 and the second end of the eighth interface 44;

[0119] The first end of the eighth interface 44 is connected to the second end of the in-vehicle evaporator 111, and the second end of the eighth interface 44 is selectively connected to the second end of the fifth interface 41 and the second end of the seventh interface 43.

[0120] In some embodiments, as Figure 7As shown, the air-conditioning module 10 includes: a fifth throttle valve 61, a second on-off valve 65, and a sixth throttle valve 63. The first end of the fifth throttle valve 61 is connected to the second end of the in-vehicle condenser 112, and the second end of the fifth throttle valve 61 is connected to the first end of the fifth interface 41. The first end of the second on-off valve is connected to the second end of the refrigerator heat exchanger 21, and the second end of the second on-off valve 65 is connected to the inlet of the compressor 13. The first end of the sixth throttle valve 63 is connected to the outlet of the compressor 13, and the second end of the sixth throttle valve 63 is connected to the second end of the refrigerator heat exchanger 21. The refrigerator module 20 includes a seventh throttle valve 62. The first end of the seventh throttle valve 62 is connected to the second end of the out-of-vehicle heat exchanger 12 and the first end of the in-vehicle evaporator 111, and the second end of the seventh throttle valve 62 is connected to the first end of the refrigerator heat exchanger 21.

[0121] In some embodiments, as Figure 7 shown, the thermal management system 100 has a second refrigerator independent refrigeration state. When the thermal management system 100 is in the second refrigerator independent refrigeration state, the fifth throttle valve 61, the seventh throttle valve 62, and the second on-off valve 65 are opened, the sixth throttle valve 63 is closed, and the fifth interface 41 and the sixth interface 42 are communicated.

[0122] In this embodiment, in the second refrigerator independent refrigeration state, the compressor 13 sucks in low-temperature and low-pressure refrigerant gas, compresses it to form high-temperature and high-pressure refrigerant gas, which flows through the in-vehicle condenser 112, the fifth throttle valve 61, the second four-way valve 40 to the out-of-vehicle heat exchanger 12 for condensation and heat release. Then, the high-pressure liquid refrigerant is throttled by the seventh throttle valve 62 and evaporates and absorbs heat in the refrigerator heat exchanger 21, and then enters the gas-liquid separator 15 through the second on-off valve 65 and returns to the compressor 13 to form a cycle.

[0123] In some embodiments, as Figure 8 shown, the thermal management system 100 has a second refrigerator independent heating state. When the thermal management system 100 is in the second refrigerator independent heating state, the sixth throttle valve 63 and the seventh throttle valve 62 are opened, the fifth throttle valve 61 and the second on-off valve 65 are closed, and the sixth interface 42 and the seventh interface 43 are communicated.

[0124] In this embodiment, in the second refrigerator independent heating state, the compressor 13 sucks in low-temperature and low-pressure refrigerant gas, compresses it to form high-temperature and high-pressure refrigerant gas, which flows through the sixth throttle valve 63 to the refrigerator heat exchanger 21 for condensation and heat release, and then is throttled by the seventh throttle valve 62 to the out-of-vehicle heat exchanger 12 for evaporation and heat absorption. Then, it enters the second four-way valve 40 through the sixth interface 42 and flows from the seventh interface 43 to the gas-liquid separator 15, and then returns to the compressor 13 to complete a cycle.

[0125] In some embodiments, as Figure 9As shown, the air-conditioning module 10 further includes: an eighth throttle valve 64. The first end of the eighth throttle valve 64 is selectively connected to the second end of the external heat exchanger 12 and the first end of the seventh throttle valve 62, and the second end of the eighth throttle valve 64 is connected to the first end of the internal evaporator 111.

[0126] In some embodiments, as Figure 9 shown, the thermal management system 100 has a state of synchronous refrigeration of the second refrigerator and the air conditioner; when the thermal management system 100 is in the state of synchronous refrigeration of the second refrigerator and the air conditioner, the fifth throttle valve 61, the seventh throttle valve 62, the second on-off valve 65, and the eighth throttle valve 64 are opened, the sixth throttle valve 63 is closed, the fifth interface 41 and the sixth interface 42 are communicated, and the seventh interface 43 and the eighth interface 44 are communicated.

[0127] In this embodiment, the compressor 13 sucks in the refrigerant gas at low temperature and low pressure, compresses it to form a refrigerant gas at high temperature and high pressure, flows through the internal condenser 112, the fifth throttle valve 61, the second four-way valve 40 to the external heat exchanger 12 for condensation and heat release. Then, the high-pressure liquid refrigerant flows to the seventh throttle valve 62 for throttling and evaporates and absorbs heat in the refrigerator heat exchanger 21, then enters the gas-liquid separator 15 after passing through the second on-off valve 65, and then returns to the compressor 13 to complete the refrigerator-side cycle. The other path flowing out of the external heat exchanger 12 is throttled by the eighth throttle valve 64, then evaporates and absorbs heat in the internal evaporator 111, enters the second four-way valve 40 from the eighth interface 44, and flows to the gas-liquid separator 15 from the seventh interface 43 to complete the air-conditioning side cycle. While the air-conditioning module 10 is refrigerating, the refrigerator module 20 is refrigerating. At this time, the refrigeration of the refrigerator module 20 is realized by using the refrigeration of the air-conditioning module 10.

[0128] In some embodiments, as Figure 10 shown, the thermal management system 100 has a state of second air-conditioning refrigeration and refrigerator heating; when the thermal management system 100 is in the state of second air-conditioning refrigeration and refrigerator heating, the fifth throttle valve 61, the eighth throttle valve 64, the sixth throttle valve 63, and the seventh throttle valve 62 are opened, the second on-off valve 65 is closed, the fifth interface 41 and the sixth interface 42 are communicated, and the seventh interface 43 and the eighth interface 44 are communicated.

[0129] In this embodiment, the compressor 13 sucks in refrigerant gas at low temperature and low pressure, and after compression, forms refrigerant gas at high temperature and high pressure. One path flows through the sixth throttle valve 63 to the refrigerator heat exchanger 21 for condensation and heat release, and then passes through the seventh throttle valve 62 which is fully open, that is, the seventh throttle valve 62 is in the second working state, and flows to before the eighth throttle valve 64. Another path flows through the vehicle condenser 112, the fifth throttle valve 61, the second four-way valve 40 to the vehicle exterior heat exchanger 12 for condensation and heat release. Then the high-pressure liquid refrigerant converges with the one path flowing through the refrigerator heat exchanger 21. After the converged refrigerant is throttled and depressurized by the eighth throttle valve 64, the two-phase refrigerant evaporates and absorbs heat in the vehicle interior evaporator 111, enters the second on-off valve 65 through the eighth interface 44, then enters the gas-liquid separator 15 from the seventh interface 43, and returns to the compressor 13 to complete a cycle.

[0130] In some embodiments, as Figure 11 shown, the thermal management system 100 has a state of synchronous heating of the second air conditioner and the refrigerator; when the thermal management system 100 is in the state of synchronous heating of the second air conditioner and the refrigerator, the fifth throttle valve 61, the eighth throttle valve 64, the sixth throttle valve 63, and the seventh throttle valve 62 are opened, the second on-off valve 65 is closed, the fifth interface 41 and the eighth interface 44 are connected, and the sixth interface 42 and the seventh interface 43 are connected.

[0131] In this embodiment, the compressor 13 sucks in refrigerant gas at low temperature and low pressure, and after compression, forms refrigerant gas at high temperature and high pressure. One path flows through the sixth throttle valve 63 to the refrigerator heat exchanger 21 for condensation and heat release, and then is throttled by the seventh throttle valve 62 and converges with another refrigerant path before flowing to the vehicle exterior heat exchanger 12. Another path flows through the vehicle condenser 112 for primary condensation and heat release, the fifth throttle valve 61, the first four-way valve 30 to the vehicle interior evaporator 111 for secondary condensation and heat release. Then the high-pressure liquid refrigerant is throttled by the eighth throttle valve 64 and converges with the one path flowing through the refrigerator heat exchanger 21 before flowing to the vehicle exterior heat exchanger 12. After the converged refrigerant evaporates and absorbs heat in the vehicle exterior heat exchanger 12, it enters the second four-way valve 40 through the sixth interface 42 and returns to the compressor 13 from the seventh interface 43 to complete a cycle.

[0132] In some embodiments, as Figure 12 shown, the thermal management system 100 has a state of the second air conditioner heating and the refrigerator cooling; when the thermal management system 100 is in the state of the second air conditioner heating and the refrigerator cooling, the fifth throttle valve 61, the eighth throttle valve 64, the seventh throttle valve 62, and the second on-off valve 65 are opened, the sixth throttle valve 63 is closed, the fifth interface 41 and the eighth interface 44 are connected, and the sixth interface 42 and the seventh interface 43 are connected.

[0133] In this embodiment, the compressor 13 sucks in the refrigerant gas at low temperature and low pressure, compresses it to form a refrigerant gas at high temperature and high pressure, flows through the in-vehicle condenser 112 to release heat by condensation, the fifth throttle valve 61 performs a primary throttling, and the refrigerant at the intermediate pressure after the primary throttling flows into the second four-way valve 40 through the fifth interface 41, and flows to the in-vehicle evaporator 111 through the eighth interface 44 for secondary condensation and heat release. Then, the medium-pressure liquid refrigerant is throttled by the eighth throttle valve 64 and divided into two paths. One path flows to the seventh throttle valve 62 for throttling and then evaporates and absorbs heat in the refrigerator heat exchanger 21, and then returns to the compressor 13 after passing through the second on-off valve 65, completing the refrigerator-side cycle. The other path evaporates and absorbs heat in the out-of-vehicle heat exchanger 12, then enters the second four-way valve 40 through the sixth interface 42 and returns to the compressor 13 through the seventh interface 43, completing the air-conditioning-side cycle.
