[0059] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0060] Thermal management systems are often installed in automobiles to achieve thermal management of the automobile.

[0061] In the related art, the thermal management system is relatively simple, mainly including a compressor, an outdoor heat exchanger, a throttle and an indoor heat exchanger connected in sequence. Through the coordination between the compressor, the outdoor heat exchanger, the throttle and the indoor heat exchanger, the refrigerant circulates and the temperature inside the vehicle is regulated. When the set temperature is higher than the ambient temperature, the thermal management system increases the temperature inside the vehicle, and when the set temperature is lower than the ambient temperature, the thermal management system lowers the temperature inside the vehicle.

[0062] However, the above temperature control method is relatively simple and is not suitable for complex actual situations.

[0063] In order to solve the above technical problems, the present disclosure provides a control method for a thermal management system. Figure 1 For a flow chart of the control method, see Figure 1 , the control method comprises:

[0064] Step 101: Determine environmental parameters and setting parameters, where the environmental parameters include the ambient temperature and the setting parameters include the setting temperature.

[0065] Step 102: Determine the temperature difference according to the ambient temperature and the set temperature.

[0066] Step 103: Determine a temperature adjustment mode according to the ambient temperature and the temperature difference, where the temperature adjustment mode is one of a rapid cooling mode, a conventional cooling mode, a rapid heating mode and a conventional heating mode.

[0067] When controlling the thermal management system by the control method provided by the embodiment of the present disclosure, the ambient temperature of the environmental parameter and the set temperature of the set parameter are first determined, then the temperature difference is determined according to the ambient temperature and the set temperature, and finally the temperature adjustment mode is determined according to the ambient temperature and the temperature difference. Since the temperature adjustment mode is one of the rapid cooling mode, the conventional cooling mode, the rapid heating mode and the conventional heating mode, the temperature adjustment mode of the thermal management system is enriched and can be applied to complex actual situations.

[0068] Figure 2 A flow chart of another control method of a thermal management system provided in an embodiment of the present disclosure, combined with Figure 2 In this embodiment, the control method includes:

[0069] Step 201: Determine environmental parameters and setting parameters, where the environmental parameters include the ambient temperature and the setting parameters include the setting temperature.

[0070] In the above implementation, the ambient temperature is obtained through an ambient temperature sensor, and the set temperature is a manually set value.

[0071] Step 202: Determine the temperature difference according to the ambient temperature and the set temperature.

[0072] In this embodiment, the temperature difference satisfies the following relationship:

[0073] T0=|Ta-Ts| (1)

[0074] In equation (1), T0 is the temperature difference, Ta is the ambient temperature, and Ts is the set temperature.

[0075] Step 203: Determine a temperature adjustment mode according to the ambient temperature and the temperature difference, where the temperature adjustment mode is one of a rapid cooling mode, a conventional cooling mode, a rapid heating mode and a conventional heating mode.

[0076] In this embodiment, step 203 is implemented in the following manner.

[0077] First, determine the range set of the ambient temperature. If the ambient temperature is in the first temperature range set, the temperature adjustment mode is the rapid cooling mode or the conventional cooling mode. If the ambient temperature is in the second temperature range set, the temperature adjustment mode is the rapid heating mode or the conventional heating mode.

[0078] In this embodiment, the first temperature interval set includes three intervals: Ta>40°C, 30°C<Ta<40°C, and 22°C<Ta<30°C. When the ambient temperature is in the above three intervals, the temperature adjustment mode is the fast cooling mode or the normal cooling mode, indicating that the temperature inside the vehicle needs to be lowered.

[0079] The second temperature interval set includes three intervals: 0℃<Ta<22℃, -10℃<Ta<0℃, and -30℃<Ta<-10℃. When the ambient temperature is in the above three intervals, the temperature adjustment mode is the fast heating mode or the normal heating mode, indicating that the temperature inside the vehicle needs to be increased.

[0080] Then, determine the interval set where the temperature insert is located. If the ambient temperature is in the first temperature interval set and the temperature difference is in the first difference interval set, the temperature adjustment mode is the rapid cooling mode. If the ambient temperature is in the first temperature interval set and the temperature difference is in the second difference interval set, the temperature adjustment mode is the conventional cooling mode. If the ambient temperature is in the second temperature interval set and the temperature difference is in the third difference interval set, the temperature adjustment mode is the rapid heating mode. If the ambient temperature is in the second temperature interval set and the temperature difference is in the fourth difference interval set, the temperature adjustment mode is the conventional heating mode.

[0081] In this embodiment, when Ta>40℃, T0>15℃, the temperature control mode is the rapid cooling mode, at which time the compressor and blower work at maximum power; when Ta>40℃, T0<15℃, the temperature control mode is the conventional cooling mode, at which time the compressor and blower work at 70% of their maximum power.

[0082] When 30℃<Ta<40℃, T0>15℃, the temperature control mode is the rapid cooling mode, at which time the compressor and blower work at maximum power. When 30℃<Ta<40℃, T0<15℃, the temperature control mode is the conventional cooling mode, at which time the compressor and blower work at 70% of their maximum power.

[0083] When 22℃<Ta<30℃, T0<4℃, the temperature control mode is the rapid cooling mode, at which time the compressor and blower work at 50% of the maximum power. When 22℃<Ta<30℃, T0>4℃, the temperature control mode is the conventional cooling mode, at which time the compressor and blower work at 30% of the maximum power.

[0084] When 0℃<Ta<22℃, T0>10℃, the temperature control mode is the rapid heating mode, at which time the heater and blower work at 70% of the maximum power. When 0℃<Ta<22℃, T0<10℃, the temperature control mode is the normal heating mode, at which time the heater and blower work at 50% of the maximum power.

[0085] When -10℃<Ta<0℃, T0>27℃, the temperature control mode is the rapid heating mode, at which time the heater and blower work at 90% of the maximum power. When -10℃<Ta<0℃, T0 is less than 27℃, the temperature control mode is the conventional heating mode, at which time the heater and blower work at 70% of the maximum power.

[0086] When -30℃<Ta<-10℃, T0>32℃, the temperature control mode is the rapid heating mode, at which time the heater and blower work at maximum power. When -30℃<Ta<-10℃, T0 is less than 32℃, the temperature control mode is the normal heating mode, at which time the heater and blower work at maximum power.

[0087] Step 204: Determine the air vent opening and closing mode.

[0088] In this embodiment, the air vent opening and closing mode is achieved in the following manner.

[0089] First, determine the seats where the occupants will be seated.

[0090] Then, the air vent opening and closing mode is determined according to the seat occupied by the occupant.

[0091] In this embodiment, when there is an occupant in the left seat of the front row, the air vent opening and closing mode is that the left air vent in the front row and the left middle air vent in the front row are opened. When there is an occupant in the right seat of the front row, the air vent opening and closing mode is that the right air vent in the front row and the right middle air vent in the front row are opened. When there is an occupant in the left seat of the back row, the air vent opening and closing mode is that the left air vent in the back row and the left middle air vent in the front row are opened. When there is an occupant in the right seat of the back row, the air vent opening and closing mode is that the right air vent in the back row and the right middle air vent in the front row are opened.

[0092] In the above implementation, when there is an occupant in a certain seat, the corresponding air outlet will be opened, and correspondingly, the other air outlets will be closed. In this way, the temperature-controlled gas can be delivered to the seat where the occupant is present, achieving precise air supply.

[0093] For example, if there are passengers in the front left seat and the front right seat, the front left air vents, the front center left air vents, the front right air vents and the front center right air vents are opened, and the rear left air vents and the rear right air vents are closed. If there are passengers in the front left seat and the rear right seat, the front left air vents, the front center left air vents, the rear right air vents and the front center right air vents are opened, and the front right air vents and the rear left air vents are closed.

[0094] Figure 3 A schematic diagram of a control system of a thermal management system provided by an embodiment of the present disclosure, combined with Figure 3 In this embodiment, the control system includes a parameter determination module 100 , a difference determination module 200 and a temperature adjustment module 300 .

[0095] The parameter determination module 100 is used to determine environmental parameters and setting parameters, the environmental parameters include the environmental temperature, and the setting parameters include the setting temperature;

[0096] The difference determination module 200 is used to determine the temperature difference according to the ambient temperature and the set temperature;

[0097] The temperature adjustment module 300 is used to determine a temperature adjustment mode according to the ambient temperature and the temperature difference. The temperature adjustment mode is one of a rapid cooling mode, a conventional cooling mode, a rapid heating mode and a conventional heating mode.

[0098] The above control system has the same beneficial effects as the above control method, which will not be described in detail here.

[0099] Figure 4 is a schematic diagram of a computer device provided by an embodiment of the present disclosure, combined with Figure 4 , the computer device 400 may include one or more of the following components: a processor 401 , a memory 402 , a communication interface 403 , and a bus 404 .

[0100] The processor 401 includes one or more processing cores, and the processor 401 executes various functional applications and information processing by running software programs and modules. The memory 402 and the communication interface 403 are connected to the processor 401 through the bus 404. The memory 402 can be used to store at least one instruction, and the processor 401 is used to execute the at least one instruction to implement each step in the above method.

[0101] In addition, the memory 402 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, and the volatile or non-volatile storage device includes but is not limited to: a magnetic disk or an optical disk, an electrically erasable programmable read-only memory (EEPROM), an erasable programmable read-only memory (EPROM), a static random access memory (SRAM), a read-only memory (ROM), a magnetic memory, a flash memory, and a programmable read-only memory (PROM).

[0102] The embodiments of the present disclosure also provide a non-temporary computer-readable storage medium. When the instructions in the storage medium are executed by a processor of a computer device, the computer device can execute the above control method of the thermal management system provided by the embodiments of the present disclosure.

[0103] A computer program product containing instructions, when running on a computer, enables the computer to execute the above control method of the thermal management system provided in the embodiment of the present application.

[0104] Figure 5 A schematic diagram of a thermal management system provided by an embodiment of the present disclosure is shown in FIG. Figure 5 The thermal management system is applicable to the control method of the thermal management system described above. In the present embodiment, the thermal management system includes a compressor 1, an indoor heat exchange component 2, an outdoor heat exchange component 3, a first throttle 4 and a second throttle 5.

[0105] The first port and the second port of the first throttle 4 are respectively connected to the first port of the indoor heat exchange component 2 and the first port of the outdoor heat exchange component 3. The first port of the second throttle 5 is respectively connected to the first port of the indoor heat exchange component 2 and the second port of the outdoor heat exchange component 3, and the second port of the second throttle 5 is connected to the second port of the indoor heat exchange component 2. The first port and the second port of the compressor 1 are respectively connected to the third port and the fourth port of the indoor heat exchange component 2. When the thermal management system is in the rapid heating mode, the first port of the indoor heat exchange component 2 is connected to the first throttle 4, and when the thermal management system is in the normal heating mode, the first port of the indoor heat exchange component 2 is connected to the second throttle 5.

[0106] When the thermal management system is working, it includes a rapid heating mode and a normal heating mode.

[0107] When the thermal management system is in the normal heating mode, the first port of the indoor heat exchange component 2 is connected to the second throttle 5, and the refrigerant flows through the first port and the second port of the compressor 1, the fourth port and the first port of the indoor heat exchange component 2, the first port and the second port of the second throttle 5, the second port and the third port of the indoor heat exchange component 2, and finally returns to the first port of the compressor 1. In this state, the refrigerant is throttled only through the second throttle 5.

[0108] When the thermal management system is in the rapid heating mode, the first port of the indoor heat exchange component 2 is connected to the first throttle 4, and the refrigerant flows through the first port and the second port of the compressor 1, the fourth port and the first port of the indoor heat exchange component 2, the first port and the second port of the first throttle 4, the first port and the second port of the outdoor heat exchange component 3, the first port and the second port of the second throttle 5, the second port and the third port of the indoor heat exchange component 2, and finally returns to the first port of the compressor 1. In this state, the refrigerant is throttled not only through the second throttle, but also through the first throttle 4.

[0109] That is to say, the thermal management system has two working modes, wherein, in the conventional heating mode, the refrigerant does not pass through the outdoor heat exchange component 3 and the first throttle 4, but only circulates between the compressor 1, the indoor heat exchange component 2, and the second throttle 5. It is possible to achieve heating and dehumidification of the indoor environment (passenger compartment). In the rapid heating mode, the refrigerant circulates between the compressor 1, the indoor heat exchange component 2, the outdoor heat exchange component 3, the first throttle 4, and the second throttle 5, so that the refrigerant can be throttled more fully. While achieving heating and dehumidification of the indoor environment, it also effectively reduces the load of the compressor 1 and improves the energy efficiency ratio of the thermal management system.

[0110] In the above implementation, the indoor heat exchange assembly 2 is used to realize heat exchange between the refrigerant and the indoor environment, and the outdoor heat exchange assembly 3 is used to realize heat exchange between the refrigerant and the outdoor environment (outside the passenger compartment). The indoor heat exchange assembly 2 and the outdoor heat exchange assembly 3 are introduced below.

[0111] In this embodiment, the indoor heat exchange component 2 includes an indoor evaporator 21 and an indoor condenser 22, the indoor evaporator 21 is respectively connected to the second port and the third port of the indoor heat exchange component 2, and the indoor condenser 22 is respectively connected to the first port and the fourth port of the indoor heat exchange component 2. The outdoor heat exchange component 3 includes an outdoor heat exchanger 31, and the outdoor heat exchanger 31 is respectively connected to the first port and the second port of the outdoor heat exchange component 3.

[0112] In the above implementation, the refrigerant flows through the indoor evaporator 21 through the second port and the third port of the indoor heat exchange component 2, the refrigerant flows through the indoor condenser 22 through the first port and the fourth port of the indoor heat exchange component 2, and the refrigerant flows through the outdoor heat exchanger 31 through the first port and the second port of the outdoor heat exchange component 3.

[0113] The thermal management system provided in the embodiment of the present disclosure has multiple other working modes in addition to the first working mode (conventional heating mode) and the second working mode (rapid heating mode) mentioned above, which are introduced below one by one.

[0114] For the third working mode, in this embodiment, the second port of the compressor 1 is connected to the first port of the outdoor heat exchange component 3 .

[0115] When the thermal management system is working, the refrigerant flows sequentially through the first port and the second port of the compressor 1, the first port and the second port of the outdoor heat exchange component 3, the first port and the second port of the second throttle 5, the second port and the third port of the indoor heat exchanger 23, and finally returns to the first port of the compressor 1. In this way, a loop is formed, which can realize cooling and dehumidification of the indoor environment.

[0116] For electric vehicles, the thermal management system not only regulates the temperature of the passenger compartment, but also involves regulating the temperature of the battery and motor. The following is an introduction to the application of thermal management systems in electric vehicles.

[0117] In this embodiment, the thermal management system further includes a third throttle 6 and a battery cooler 7, wherein the first port of the third throttle 6 is connected to the first port of the indoor heat exchange component 2 and the second port of the outdoor heat exchange component 3, respectively, the second port of the third throttle 6 is connected to the first port of the battery cooler 7, and the second port of the battery cooler 7 is connected to the first port of the compressor 1. The first port of the indoor heat exchange component 2 can be selectively connected to the first throttle 4 or the third throttle 6.

[0118] In the above implementation, since the first port of the indoor heat exchange component 2 can be selectively connected to the first throttle 4 or the third throttle 6, it can have a primary throttling mode and a secondary throttling mode.

[0119] When the thermal management system is in the first-level throttling mode, corresponding to the fourth working mode of the thermal management system, the first port of the indoor heat exchange component 2 is connected to the third throttle 6. At this time, the refrigerant flows through the first port and the second port of the compressor 1, the fourth port and the first port of the indoor heat exchange component 2, the first port and the second port of the third throttle 6, the first port and the second port of the battery cooler 7, and finally returns to the first port of the compressor 1. In this state, the refrigerant is throttled only through the third throttle 6.

[0120] When the thermal management system is in the secondary throttling mode, corresponding to the fifth working mode of the thermal management system, the first port of the indoor heat exchange component 2 is connected to the first throttle 4, and the refrigerant flows through the first port and the second port of the compressor 1, the fourth port and the first port of the indoor heat exchange component 2, the first port and the second port of the first throttle 4, the first port and the second port of the outdoor heat exchange component 3, the first port and the second port of the third throttle 6, the first port and the second port of the battery cooler 7, and finally returns to the first port of the compressor 1. In this state, the refrigerant is throttled not only through the three throttles, but also through the first throttle 4.

[0121] That is to say, in the first-level throttling mode, the refrigerant does not pass through the outdoor heat exchange component 3 and the first throttle 4, but only circulates between the compressor 1, the indoor heat exchange component 2, the battery cooler 7 and the third throttle 6. In this case, the waste heat of the battery cooler 7 can be effectively recovered, which can not only effectively cool the battery, but also better heat and dehumidify the passenger compartment. In the second-level throttling mode, the refrigerant circulates between the compressor 1, the indoor heat exchange component 2, the outdoor heat exchange component 3, the battery cooler 7, the first throttle 4 and the third throttle 6, so that the refrigerant can be throttled more fully. While achieving heating and dehumidification of the indoor environment, it also effectively reduces the load of the compressor 1 and improves the energy efficiency ratio of the thermal management system.

[0122] For the sixth working mode, in this embodiment, the second port of the compressor 1 is connected to the first port of the outdoor heat exchanger 31 .

[0123] When the thermal management system is working, the refrigerant flows sequentially through the first port and the second port of the compressor 1, the first port and the second port of the outdoor heat exchange component 3, the first port and the second port of the third throttle 6, the first port and the second port of the battery cooler 7, and finally returns to the first port of the compressor 1. In this way, a loop is formed to cool the battery.

[0124] The various working modes described above all involve the operation of the compressor 1 . The working modes not involving the compressor 1 will be introduced below.

[0125] For the seventh working mode, in this embodiment, the thermal management system also includes a motor package 8 and a multi-way valve 9, the first port and the second port of the motor package 8 are respectively connected to the first port of the multi-way valve 9 and the third port of the outdoor heat exchange component 3, and the second port of the multi-way valve 9 is connected to the fourth port of the outdoor heat exchange component 3.

[0126] When the thermal management system is working, the coolant flows sequentially through the first port and the second port of the motor package 8, the third port and the fourth port of the outdoor heat exchange component 3, the second port and the first port of the multi-way valve 9, and finally returns to the first port of the motor package 8. In this way, a loop is formed to achieve cooling of the motor.
