[0035] In this embodiment, the method for controlling the circulation system is applied to an electronic device. The electronic device is the vehicle infotainment system in a new energy vehicle. The circulation system includes an air conditioning system and a liquid cooling system. The liquid cooling system is used to dissipate heat from heat sources generated by the new energy vehicle. These heat sources include electrical components such as batteries and motors. The air conditioning system is used to controllably exchange heat with the liquid cooling system to absorb the heat generated by the liquid cooling system. The air conditioning system is also used to controllably cool or heat the passenger compartment of the new energy vehicle. Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of a cyclic system. Figure 2 This is a schematic diagram of another circulating system. The circulating system includes a liquid cooling system and an air conditioning system. The air conditioning system includes a compressor 1, a four-way valve 2, an internal heat exchanger 3, a first throttling device 4, an external heat exchanger 5, a second throttling device 6, and a first coil 7 of the heat exchanger. The liquid cooling system includes a pump 9, a heat source 10, a three-way valve, an external cooler 12, and a second coil 8 of the heat exchanger. The three-way valve includes a first three-way valve 11 and a second three-way valve 13. The internal heat exchanger 3 is connected to the cockpit space and exchanges heat with the air inside the cockpit. The external heat exchanger 5 is connected to the ambient air outside the cockpit and exchanges heat with the ambient air. The heat exchanger includes a first coil and a second coil. The heat exchanger is used for heat transfer, enabling heat exchange between the two refrigerants in the first and second coils. The first three-way valve 11 and the second three-way valve 13 are configured to allow the refrigerant from the liquid cooling system to enter the external cooler and exchange heat with the ambient air when laterally open. The first three-way valve 11 and the second three-way valve 13 are configured to short-circuit the external cooler 12 when longitudinally open.

[0036] Figure 1The structural schematic diagram of the circulation system shown is a structural schematic diagram in the case where the four-way valve executes the second action. The four-way valve is configured to conduct the compressor and the outer heat exchanger in the case of executing the second action, and conduct the inner heat exchanger and the first coil pipe of the heat exchanger. In some embodiments, in the case where the running state of the air conditioning system is the refrigeration running state, the electronic device controls the four-way valve to execute the first action, at which time the compressor and the outer heat exchanger are conducted, and the inner heat exchanger and the first coil pipe of the heat exchanger are conducted. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor enters the outer heat exchanger through the four-way valve to be condensed, and then flows through the first throttling device to form low-temperature and low-pressure gas-liquid mixed state refrigerant, at which time the first throttling device is in a throttling state. The low-temperature and low-pressure gas-liquid mixed state refrigerant enters the inner heat exchanger to be evaporated, so as to realize refrigeration in the cockpit. The low-temperature and low-pressure gas-liquid mixed state refrigerant enters the inner heat exchanger to be evaporated to form low-temperature and low-pressure gaseous refrigerant, which enters the first coil pipe of the heat exchanger to be evaporated and absorb heat. Since the heat exchanger includes the first coil pipe and the second coil pipe, the high-temperature refrigerant in the liquid cooling system enters the second coil pipe of the heat exchanger, so that heat exchange between the air conditioning system and the liquid cooling system can be realized through the heat exchanger, so as to absorb the heat generated by the liquid cooling system.

[0037] Figure 2 The structural schematic diagram of the circulation system shown is a structural schematic diagram in the case where the four-way valve executes the second action. The four-way valve is configured to conduct the compressor and the outer heat exchanger in the case of executing the second action, and conduct the inner heat exchanger and the first coil pipe of the heat exchanger. In some embodiments, in the case where the running state of the air conditioning system is the refrigeration running state, the electronic device controls the four-way valve to execute the first action, at which time the compressor and the outer heat exchanger are conducted, and the inner heat exchanger and the first coil pipe of the heat exchanger are conducted. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor enters the outer heat exchanger through the four-way valve to be condensed, and then flows through the first throttling device to form low-temperature and low-pressure gas-liquid mixed state refrigerant, at which time the first throttling device is in a throttling state. The low-temperature and low-pressure gas-liquid mixed state refrigerant enters the inner heat exchanger to be evaporated, so as to realize refrigeration in the cockpit. The low-temperature and low-pressure gas-liquid mixed state refrigerant enters the inner heat exchanger to be evaporated to form low-temperature and low-pressure gaseous refrigerant, which enters the first coil pipe of the heat exchanger to be evaporated and absorb heat. Since the heat exchanger includes the first coil pipe and the second coil pipe, the high-temperature refrigerant in the liquid cooling system enters the second coil pipe of the heat exchanger, so that heat exchange between the air conditioning system and the liquid cooling system can be realized through the heat exchanger, so as to absorb the heat generated by the liquid cooling system.

[0038] In some embodiments, in the case where the running state of the air conditioning system is the heating running state, the electronic device controls the four-way valve to execute the first action, at which time the compressor and the outer heat exchanger are conducted, and the inner heat exchanger and the first coil pipe of the heat exchanger are conducted. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor enters the inner heat exchanger through the four-way valve to be condensed, so as to realize heating in the cockpit. The high-temperature and high-pressure gaseous refrigerant after condensation becomes low-temperature and low-pressure gas-liquid mixed state refrigerant through the first throttling device, at which time the first throttling device is in a throttling state. The low-temperature and low-pressure gas-liquid mixed state refrigerant enters the outer heat exchanger to be evaporated. At this time, the second throttling device is in a full opening state or a throttling state, and the low-temperature and low-pressure gas-liquid mixed state refrigerant after evaporation passes through the four-way valve and then the second throttling device to enter the first coil pipe of the heat exchanger to be evaporated and absorb heat. Since the heat exchanger includes the first coil pipe and the second coil pipe, the high-temperature refrigerant in the liquid cooling system enters the second coil pipe of the heat exchanger, so that heat exchange between the air conditioning system and the liquid cooling system can be realized through the heat exchanger, so as to absorb the heat generated by the liquid cooling system.

[0039] In combination Figure 3 shown, Figure 3 is another structural schematic diagram of a circulation system. Figure 3The middle circulation system comprises a liquid cooling system 14 and an air conditioning system 15. The liquid cooling system 14 is used to cool the heat source to generate heat. The air conditioning system 15 is used to exchange heat with the liquid cooling system 14 to absorb the heat generated by the liquid cooling system.

[0040] Optionally, one side of the inner heat exchanger is provided with a first fan, and the first fan is controlled to exchange heat between the inner heat exchanger and the air in the cockpit. In the case that the operating state of the air conditioning system is a refrigeration operating state, the first fan is controlled to start, so that the cold energy generated by the evaporation of the inner heat exchanger can be exchanged with the air in the cockpit. In the case that the operating state of the air conditioning system is a heating operating state, the first fan is controlled to start, so that the heat generated by the condensation of the inner heat exchanger can be exchanged with the air in the cockpit.

[0041] Optionally, one side of the outer heat exchanger is provided with a second fan, and the second fan is controlled to exchange heat between the outer heat exchanger and the air in the external environment, and to exchange heat between the outer cooler and the air in the external environment. In some embodiments, the second fan is controlled to start according to the operating state of the liquid cooling system and the operating state of the air conditioning system.

[0042] Optionally, the second fan is controlled to start according to the operating state of the liquid cooling system and the operating state of the air conditioning system, comprising: in the case that the operating state of the liquid cooling system is a working state, and the operating state of the air conditioning system is a stop working state, the second fan is controlled to start. In this way, in the case that the liquid cooling system is in a working state, the high-temperature refrigerant in the liquid cooling system enters the outer cooler to be cooled down, and by starting the second fan, the heat exchange between the outer cooler and the air in the external environment can be enhanced, thereby improving the cooling effect.

[0043] Optionally, the second fan is controlled to start according to the operating state of the liquid cooling system and the operating state of the air conditioning system, comprising: in the case that the operating state of the liquid cooling system is a working state, and the operating state of the air conditioning system is a heating operating state, the second fan is controlled to start. In this way, since the liquid cooling system is in a working state, and the air conditioning system is also in a heating operating state, by starting the second fan, the heat exchange between the outer cooler and the air in the external environment can be enhanced, and the heat exchange between the outer heat exchanger and the air in the external environment can also be enhanced.

[0044] Further, the control of the second fan to start comprises: acquiring the temperature of the outer cooler and the temperature of the outer heat exchanger. In the case that the temperature of the outer cooler is higher than the temperature of the outer heat exchanger, the second fan is controlled to rotate forward, so that the air flows through the outer heat exchanger first and then flows through the outer cooler. Or, in the case that the temperature of the outer cooler is lower than the temperature of the outer heat exchanger, the second fan is controlled to reverse, so that the air flows through the outer cooler first and then flows through the outer heat exchanger.

[0045] In combination Figure 4As shown, the embodiment of the present disclosure provides a method for controlling a circulating system, the circulating system comprising an air conditioning system and a liquid cooling system, the air conditioning system being used to control heat exchange with the liquid cooling system to absorb heat generated by the liquid cooling system; the method comprising:

[0046] In step S401, the electronic device acquires the operating state of the liquid cooling system and the operating state of the air conditioning system.

[0047] In step S402, the electronic device controls heat exchange of the circulating system according to the operating state of the liquid cooling system and the operating state of the air conditioning system.

[0048] The method for controlling the circulating system provided by the embodiment of the present disclosure acquires the operating state of the liquid cooling system and the operating state of the air conditioning system. The heat exchange of the circulating system is controlled according to the operating state of the liquid cooling system and the operating state of the air conditioning system. In this way, the operating state of the liquid cooling system and the operating state of the air conditioning system are acquired respectively. In the case of different operating states of the liquid cooling system and different operating states of the air conditioning system, different heat exchange control is performed on the circulating system, which can timely absorb the heat generated by the liquid cooling system. The liquid cooling system is effectively cooled, so that the air conditioning system will not be shut down due to insufficient cooling of the liquid cooling system, thereby achieving the effect of continuous refrigeration and heating in different scenarios.

[0049] Optionally, one side of the external heat exchanger is provided with a second fan, and the other side of the external heat exchanger is provided with an external cooler. The second fan is used to control heat exchange between the external heat exchanger and the external environment air and heat exchange between the external cooler and the external environment air. The electronic device controls heat exchange of the circulating system according to the operating state of the liquid cooling system and the operating state of the air conditioning system, which comprises: the electronic device controls the second fan to start in the case that the operating state of the liquid cooling system is a working state and the operating state of the air conditioning system is a stop working state. In this way, since the operating state of the liquid cooling system is a working state and the operating state of the air conditioning system is a stop working state, it is considered that the heat source needs to be cooled and the cockpit has no refrigeration demand at this time. The second fan is controlled to start, which can enhance the heat exchange between the external heat exchanger and the external cooler and the external environment air, thereby improving the cooling effect.

[0050] Further, the liquid cooling system generates heat when cooling the heat source in the working state. The air conditioning system includes a compressor, a four-way valve, an outer heat exchanger, an inner heat exchanger, and a first coil of the heat exchanger, and a first throttling device is arranged between the outer heat exchanger and the inner heat exchanger. A second throttling device is arranged between the four-way valve and the first coil of the heat exchanger. The four-way valve is configured to conduct the compressor and the inner heat exchanger when performing a first action, and to conduct the outer heat exchanger and the first coil of the heat exchanger. When the four-way valve performs the first action, and the first throttling device is in a fully open state and the second throttling device is in a throttling state, the outer heat exchanger and the inner heat exchanger are used to condense the refrigerant. The electronic device controls the heat exchange of the circulation system according to the operating state of the liquid cooling system and the operating state of the air conditioning system, including: the electronic device monitors the temperature of the heat source when the operating state of the liquid cooling system is the working state and the operating state of the air conditioning system is the stop working state, and obtains a first temperature monitoring value. When the first temperature monitoring value is greater than a preset value, the air conditioning system is started, and the four-way valve is controlled to perform the first action, and the first throttling device is controlled to be in a fully open state and the second throttling device is controlled to be in a throttling state.

[0051] In this way, even when the air conditioning system does not perform refrigeration or heating, heat exchange with the liquid cooling system can be achieved to absorb the heat generated by the liquid cooling system. By obtaining the first temperature monitoring value of the heat source, it can be determined whether the external cooler can completely cool the heat source. When the first temperature monitoring value is greater than a preset value, it is considered that the liquid cooling system cannot completely cool the heat source at this time, and the air conditioning system is started by control, and the four-way valve is controlled to perform the first action, and the first throttling device is controlled to be in a fully open state and the second throttling device is controlled to be in a throttling state. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor enters the outer heat exchanger and the inner heat exchanger to condense, and the condensed refrigerant becomes low-temperature and low-pressure gas-liquid mixed state refrigerant after passing through the second throttling device in a throttling state, and then enters the first coil of the heat exchanger to evaporate, thereby achieving heat exchange with the liquid cooling system and absorbing the heat generated by the liquid cooling system.

[0052] In some embodiments, the liquid cooling system includes a pump, a heat source, a three-way valve, an external cooler, and a second coil of a heat exchanger. The three-way valve includes a first three-way valve and a second three-way valve. When the operating state of the liquid cooling system is the working state, the electronic device controls the pump to start, so that the refrigerant of the liquid cooling system flows through the heat source to dissipate heat. After the refrigerant of the liquid cooling system flows through the heat source, the refrigerant of the liquid cooling system flows through the first three-way valve into the external cooler to exchange heat with the ambient air and be cooled when the first three-way valve and the second three-way valve are in a transverse conduction state. After the refrigerant of the liquid cooling system enters the external cooler, it enters the second coil of the heat exchanger through the second three-way valve to exchange heat with the refrigerant of the air conditioning system.

[0053] In some embodiments, when the first three-way valve and the second three-way valve are in the longitudinal conduction state, the refrigerant of the liquid cooling system does not enter the external cooler, but directly enters the second coil of the heat exchanger from the pipeline between the first three-way valve and the second three-way valve, and exchanges heat with the refrigerant of the air conditioning system.

[0054] Further, the first throttling device is arranged between the external heat exchanger and the internal heat exchanger, and the second throttling device is arranged between the four-way valve and the first coil of the heat exchanger. The four-way valve is configured to conduct the compressor and the external heat exchanger when performing the second action, and conduct the internal heat exchanger and the first coil of the heat exchanger. When the four-way valve performs the second action, and the first throttling device is in the throttling state, and the second throttling device is in the full open state or the throttling state, the external heat exchanger is used to condense the refrigerant, and the internal heat exchanger is used to evaporate the refrigerant. The electronic device performs heat exchange control on the circulation system according to the operating state of the liquid cooling system and the operating state of the air conditioning system, including: when the operating state of the liquid cooling system is the working state, and the operating state of the air conditioning system is the refrigeration operating state, the electronic device controls the four-way valve to perform the second action, and controls the first throttling device to be in the throttling state, and the second throttling device to be in the full open state or the throttling state.

[0055] In this way, since the operating state of the liquid cooling system is the working state, and the operating state of the air conditioning system is the refrigeration operating state, it is considered that the heat source needs to be cooled and the cockpit needs to be refrigerated at this time. By controlling the four-way valve to perform the second action, and controlling the first throttling device to be in the throttling state, and the second throttling device to be in the full open state or the throttling state. In this way, the high-temperature and high-pressure gaseous refrigerant discharged by the compressor enters the external heat exchanger to be condensed, and then flows through the first throttling device in the throttling state to become low-temperature and low-pressure gas-liquid mixed state refrigerant, and then enters the internal heat exchanger to be evaporated, thereby refrigerating the cockpit. The low-temperature and low-pressure gas-liquid mixed state refrigerant enters the first coil of the heat exchanger after flowing through the second throttling device to evaporate, thereby realizing heat exchange with the liquid cooling system and absorbing the heat generated by the liquid cooling system.

[0056] In some embodiments, when the electronic device is in the operating state of the liquid cooling system is the working state, and the operating state of the air conditioning system is the refrigeration operating state, the first fan is started to exchange heat with the cockpit.

[0057] Further, the air conditioning system comprises a compressor, a four-way valve, an outer heat exchanger, an inner heat exchanger and a first coil of the heat exchanger. The first throttling device is arranged between the outer heat exchanger and the inner heat exchanger, and the second throttling device is arranged between the four-way valve and the first coil of the heat exchanger. The four-way valve is configured to conduct the compressor and the inner heat exchanger, and conduct the outer heat exchanger and the first coil of the heat exchanger when performing a first action. When the four-way valve performs the first action, and the first throttling device is in a throttling state, and the second throttling device is in a full open state or a throttling state, the inner heat exchanger is used to condense the refrigerant, and the outer heat exchanger is used to evaporate the refrigerant. The electronic device performs heat exchange control on the circulating system according to the operating state of the liquid cooling system and the operating state of the air conditioning system, including: when the operating state of the liquid cooling system is a working state, and the operating state of the air conditioning system is a heating operating state, the electronic device controls the four-way valve to perform the first action, and controls the first throttling device to be in a throttling state, and the second throttling device to be in a full open state or a throttling state.

[0058] In this way, since the operating state of the liquid cooling system is a working state, and the operating state of the air conditioning system is a heating operating state, it is considered that the heat source needs to be cooled and the cockpit needs to be heated at this time. By controlling the four-way valve to perform the first action, and controlling the first throttling device to be in a throttling state, and the second throttling device to be in a full open state or a throttling state. In this way, the high-temperature and high-pressure gaseous refrigerant discharged by the compressor enters the inner heat exchanger to be condensed, thereby heating the cockpit. After the low-temperature and low-pressure gaseous-liquid mixed refrigerant flows through the first throttling device in a throttling state after being condensed in the inner heat exchanger, it enters the outer heat exchanger to be evaporated, and then enters the first coil of the heat exchanger to be evaporated and absorb heat, thereby absorbing the heat of the liquid cooling system.

[0059] In some embodiments, when the electronic device is in a working state, and the operating state of the air conditioning system is a heating operating state, the first fan is started, and the second fan is started. In this way, by starting the first fan, the heat exchange between the inner heat exchanger and the cockpit air can be realized to achieve heating. By starting the second fan, the heat exchange between the outer heat exchanger and the outside air can be realized, thereby improving the heat dissipation effect.

[0060] Further, the liquid cooling system comprises an external cooler and a three-way valve, and the liquid cooling system is used to cool a heat source to generate heat. The three-way valve is configured to short-circuit the external cooler in a longitudinal conduction mode. The electronic device performs heat exchange control on the circulation system according to the operating state of the liquid cooling system and the operating state of the air conditioning system, including: when the operating state of the liquid cooling system is a working state and the operating state of the air conditioning system is a heating operating state, the electronic device determines whether the heat generated by the liquid cooling system can be absorbed by the air conditioning system. When the heat generated by the liquid cooling system can be absorbed by the air conditioning system, the three-way valve is controlled to be in the longitudinal conduction mode. In this way, when the heat generated by the liquid cooling system can be absorbed by the air conditioning system, the three-way valve is controlled to be in the longitudinal conduction mode, so that the refrigerant of the liquid cooling system can directly enter the second coil of the heat exchanger to heat the evaporation end of the heat pump air conditioning system, thereby improving the heating capacity of the heat pump air conditioning system.

[0061] Further, the electronic device determines whether the heat generated by the liquid cooling system can be absorbed by the air conditioning system by the following method, including: the electronic device monitors the temperature of the heat source to obtain a second temperature monitoring value. When the second temperature monitoring value is less than or equal to a preset temperature, it is determined that the heat generated by the liquid cooling system can be absorbed by the air conditioning system. Or, when the second temperature monitoring value is greater than the preset temperature, it is determined that the heat generated by the liquid cooling system cannot be absorbed by the air conditioning system.

[0062] Further, the liquid cooling system comprises an external cooler and a three-way valve, and the three-way valve is configured to make the refrigerant of the liquid cooling system enter the external cooler to exchange heat with the ambient air in a transverse conduction mode. The electronic device performs heat exchange control on the circulation system according to the operating state of the liquid cooling system and the operating state of the air conditioning system, including: when the operating state of the liquid cooling system is a working state and the operating state of the air conditioning system is a heating operating state, the electronic device determines whether the heat generated by the liquid cooling system can be absorbed by the air conditioning system. When the heat generated by the liquid cooling system cannot be absorbed by the air conditioning system, the three-way valve is controlled to be in the transverse conduction mode. In this way, when the heat generated by the liquid cooling system cannot be absorbed by the air conditioning system, the three-way valve is controlled to be in the transverse conduction mode, so that the refrigerant of the liquid cooling system can enter the external cooler to be cooled.

[0063] Further, the electronic device further performs heat exchange control on the circulation system according to the operating state of the liquid cooling system and the operating state of the air conditioning system, and the heat exchange control includes: when the outer heat exchanger needs to be defrosted, the electronic device controls the first throttling device to be in a fully open state, and controls the second throttling device to be in a throttling state. In this way, by controlling the first throttling device to be in a fully open state, the inner heat exchanger and the outer heat exchanger are connected, so that the hot refrigerant flows to the outer heat exchanger for defrosting. By controlling the second throttling device to be in a throttling state, the refrigerant evaporates in the outer heat exchanger to absorb the heat of the liquid cooling system, so that the outer heat exchanger is defrosted while continuously providing heat to the cabin.

[0064] Optionally, the heat exchanger is filled with a heat storage phase change material. The heat storage phase change material is used as an energy conversion medium of the liquid cooling system and the heat pump air conditioning system. In this way, the heat in the liquid cooling system can be stored to provide heat when the outer heat exchanger needs to be defrosted.

[0065] Further, the electronic device further performs heat exchange control on the circulation system according to the operating state of the liquid cooling system and the operating state of the air conditioning system, and the heat exchange control includes: when the outer heat exchanger needs to be defrosted, the electronic device controls the first throttling device to be in a fully open state, and controls the second throttling device to be in a throttling state. In this way, by controlling the first throttling device to be in a fully open state, the inner heat exchanger and the outer heat exchanger are connected, so that the hot refrigerant flows to the outer heat exchanger for defrosting. By controlling the second throttling device to be in a throttling state, the refrigerant evaporates in the outer heat exchanger to absorb the heat of the liquid cooling system, so that the outer heat exchanger is defrosted while continuously providing heat to the cabin.
