[0001] The present application relates to the technical field of new energy vehicle air conditioners, and more particularly, to a vehicle air conditioning device, a control method and an electronic device. Background Art

[0002] At present, the refrigeration and heating of the passenger compartment of new energy vehicles are jointly realized by a heat pump compressor or a single-cooling electric compressor and a positive temperature coefficient heater (PTC). The heat pump compressor and the heater are installed in the front compartment of the vehicle outside the passenger compartment. These components can work independently and are decoupled from the vehicle electric drive system, but this system has high costs and high system complexity. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a vehicle air conditioning device, a control method and an electronic device, in which the electric drive system drives the compressor for refrigeration or heating, and when the vehicle is stationary, the heat storage device is used to release heat for refrigeration or heating, with low structural complexity and low cost, solving the problems of high cost and high system complexity of the existing system.

[0004] The embodiments of the present application provide a vehicle air conditioning device, which includes:

[0005] A compressor, connected to the electric drive system, for realizing the compression function under the mechanical drive of the electric drive system;

[0006] An evaporator, arranged in the air conditioning box body, connected to the compressor through a pipeline, the evaporator is connected to the air inlet of the air conditioning box body through an air inlet pipeline, and the outlet end of the evaporator is connected to the air outlet of the air conditioning box body through an air outlet pipeline;

[0007] A heat storage device, arranged in the air conditioning box body, with the inlet end connected to the air outlet pipeline of the evaporator through a pipeline, and the outlet end connected to the air outlet;

[0008] At least one valve, arranged at the connection between the air outlet pipeline and the inlet end of the heat storage device, for switching the air flow path;

[0009] A controller, electrically connected to the valve and the heat storage device, for changing the working mode of the heat storage device and controlling the valve to act based on the cab environment temperature and the target temperature, so as to switch the air flow path.

[0010] In the above implementation process, the heat storage device stores a certain amount of heat during vehicle operation and can release the stored heat for refrigeration or heating when the vehicle is stationary and the compressor is not working. This can simplify the structural complexity of the compressor and the electric system, reduce the system cost, lower the working load of the compressor, and reduce the noise when the vehicle is stationary, so as to improve the comfort when the vehicle is stationary.

[0011] Further, the valve includes:

[0012] The first valve is arranged at the connection between the air outlet duct and the inlet end of the heat storage device and is used to switch the air flow path at the inlet end of the heat storage device;

[0013] The second valve is arranged at the connection between the air outlet duct and the outlet end of the heat storage device and is used to switch the air flow path at the outlet end of the heat storage device.

[0014] In the above implementation process, when the heat storage device is connected to the air outlet duct, two valves need to be set to control the air flow path to achieve accurate control of the air flow path.

[0015] Further, when the compressor is in a normal working state, the heat storage device is in a closed state, and the first valve and the second valve are controlled so that the air flowing through the evaporator directly passes through the air outlet until the current temperature in the cab reaches the target temperature.

[0016] In the above implementation process, when the current temperature in the cab has not reached the target temperature, by controlling the first valve and the second valve, the air passing through the evaporator directly passes through the air outlet to change the temperature in the cab.

[0017] Further, when the compressor is in a normal working state and the current temperature in the cab reaches the target temperature, the heat storage device is in a heat storage mode, and the positions of the first valve and the second valve are controlled so that the air flowing out of the evaporator passes through the heat storage device and the air outlet respectively, so that the heat storage device stores heat.

[0018] In the above implementation process, when the current temperature in the cab reaches the target temperature, part of the air flow can pass through the heat storage device for heat storage, while maintaining the target temperature, making full use of the energy for subsequent use.

[0019] Further, when the compressor is in a closed state, the heat storage device is in a heat release mode, and the positions of the first valve and the second valve are controlled so that the incoming air at the air inlet flows into the heat storage device, and the heat storage device releases heat to change the temperature of the incoming air.

[0020] In the above implementation process, when the vehicle is in a stationary state, the heat in the energy storage mode can be released, so that the vehicle can still be cooled or heated when it is stationary, meeting the temperature requirements of the cab. While meeting the cooling and heating requirements of the vehicle in the stationary state, the complexity of the device is simplified, the cost is reduced, and the cooling and heating requirements of the vehicle in various scenarios are met.

[0021] The embodiment of the present application also provides a control method for a vehicle air conditioning device, which is applied to the controller in the above, and the method includes:

[0022] Obtain the working parameters of the compressor to determine the working state of the compressor;

[0023] Obtain the current temperature of the cab and the preset target temperature;

[0024] Based on the working state of the compressor, the current temperature of the cab and the preset target temperature, change the working mode of the heat storage device and control the valve action to switch the air flow path.

[0025] In the above implementation process, according to the working state of the compressor, the current temperature of the cab and the preset target temperature, the working mode of the heat storage device and the valve action are controlled, so that the heat storage mode is turned on when the compressor is working normally, and the heat release mode is turned on when the vehicle is stationary, meeting the cooling and heating requirements of the vehicle in various scenarios, and simplifying the complexity of the device and reducing the cost.

[0026] Further, the working state of the compressor includes a normal working state, the valves include a first valve and a second valve, and the changing the working mode of the heat storage device and controlling the valve action to switch the air flow path based on the working state of the compressor, the current temperature of the cab and the preset target temperature includes:

[0027] Control the first valve and the second valve so that the air flowing through the evaporator directly passes through the air outlet until the current temperature of the cab reaches the target temperature.

[0028] In the above implementation process, when the current temperature of the cab has not reached the target temperature, the flow-through channel of the heat storage device is closed, so that the cooled or heated air directly acts on the cab, enabling the cab temperature to reach the target temperature as soon as possible.

[0029] Further, the working state of the compressor includes a normal working state, the valves include a first valve and a second valve, and the changing the working mode of the heat storage device and controlling the valve action to switch the air flow path based on the working state of the compressor, the current temperature of the cab and the preset target temperature includes:

[0030] When the current temperature in the cab reaches the target temperature, the heat storage device is in the heat storage mode, and the positions of the first valve and the second valve are controlled so that the air flowing out of the evaporator passes through the heat storage device and the air outlet respectively, so that the heat storage device stores heat.

[0031] In the above implementation process, after the current temperature in the cab reaches the target temperature, the heat storage mode is turned on, so that part of the air after refrigeration and heating flows into the heat storage device for storing heat, and part of it directly enters the cab, so that the cab temperature remains at the target temperature.

[0032] Further, the operating state of the compressor includes a closed state, the valves include a first valve and a second valve, and based on the operating state of the compressor, the current temperature in the cab and the preset target temperature, the operating mode of the heat storage device is changed and the valve action is controlled to switch the air flow path, including:

[0033] When the compressor is in the closed state, the heat storage device is in the heat release mode, and the positions of the first valve and the second valve are controlled so that the incoming air at the air inlet flows into the heat storage device, and the heat storage device releases heat to change the temperature of the incoming air.

[0034] In the above implementation process, when the vehicle is stationary, the heat release mode can be turned on. By controlling the first valve and the second valve, the air flows through the heat storage device for refrigeration and heating, so that the cab can still be refrigerated and heated when the vehicle is stationary, meeting the refrigeration and heating requirements of the vehicle in various scenarios.

[0035] The embodiment of the present application also provides an electronic device, which includes a memory and a processor. The memory is used to store a computer program, and the processor runs the computer program to make the electronic device execute the control method of the vehicle air conditioning device described in any one of the above.

[0043] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0044] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0045] Embodiment 1

[0046] Please refer to Figure 1 , Figure 1 This is a schematic structural diagram of a vehicle air conditioning device provided by the embodiment of the present application. In order to reduce the overall vehicle cost and the structural complexity of the air conditioning device, in the present application, the motor of the electric drive system 11 of the vehicle is used to replace the drive component of the heat pump compressor 12 or the single - cold compressor 12 in the prior art. During vehicle driving, the electric drive system 11 drives the impeller of the compressor 12 to perform refrigeration or heating work while driving the wheels; when the vehicle is stationary, without adding other auxiliary components, the electric drive motor cannot drive the compressor 12. However, adding other auxiliary components will increase the device complexity. Therefore, the present application uses the heat storage device 20 to meet the refrigeration and heating requirements when the vehicle is stationary. This device specifically includes an electric drive system 11, a compressor 12, an evaporator 14, and a heat storage device 20. Specifically:

[0047] A compressor 12, connected to an electric drive system 11, is used to achieve a compression function under the mechanical drive of the electric drive system 11; an evaporator 14, arranged inside an air-conditioning box 13, is connected to the compressor 12 through a pipeline. The evaporator 14 is connected to an air inlet 15 of the air-conditioning box 13 through an air inlet pipeline 16. An outlet end of the evaporator 14 is connected to an air outlet 19 of the air-conditioning box 13 through an air outlet pipeline 21. The refrigerant processed by the compressor 12 exchanges heat with the air entering the air-conditioning box 13 in the evaporator 14.

[0048] A heat storage device 20 is arranged inside the air-conditioning box 13. An inlet end is connected to the air outlet pipeline 21 of the evaporator 14, and an outlet end is connected to the air outlet 19.

[0049] At least one valve is arranged at a connection between the air outlet pipeline 21 and the inlet end of the heat storage device 20, and is used to switch the air flow path and control whether the air in the air outlet pipeline 21 passes through the heat storage device 20.

[0050] A controller, electrically connected to the valve and the heat storage device 20, is used to change the working mode of the heat storage device 20 and control the valve to act based on the cab environment temperature and the target temperature, so as to switch the air flow path.

[0051] Exemplarily, the number of valves can be two, including a first valve 17 and a second valve 18, where:

[0052] The first valve 17 is arranged at a connection between the air outlet pipeline 21 and the inlet end of the heat storage device 20, and is used to switch the air flow path at the inlet end of the heat storage device 20;

[0053] The second valve 18 is arranged at a connection between the air outlet pipeline 21 and the outlet end of the heat storage device 20, and is used to switch the air flow path at the outlet end of the heat storage device 20.

[0054] The device includes a refrigeration and heating mode of the compressor 12, a heat storage mode of the heat storage device 20, and a heat release mode of the heat storage device 20, which can meet the refrigeration and heating requirements in various scenario states such as when the vehicle is driving and stationary. At the same time, the complexity of the device is low, and the production cost can be reduced.

[0055] Wherein, a core body with a phase change material is arranged inside the heat storage device 20. When the compressor 12 is in the refrigeration operation, the core body can absorb the heat in the cold air and store a certain cold temperature; when the compressor 12 is in the heating operation, the core body can also absorb the heat in the hot air and store a certain hot temperature, so as to meet the refrigeration and heating requirements of the cab when the vehicle is stationary.

[0056] Wherein, the refrigeration and heating mode of the compressor 12 is:

[0057] When the compressor 12 is in a normal working state, the heat storage device 20 is in a closed state. The first valve 17 and the second valve 18 are controlled so that the air flowing through the evaporator 14 directly passes through the air outlet 19 until the current temperature in the cab reaches the target temperature.

[0058] As Figure 1 As shown in the figure, it is a schematic diagram of the independent refrigeration and heating mode of the compressor 12. At this time, the vehicle is in a normal driving state. The controller can control whether the compressor 12 operates in the refrigeration condition or the heating condition according to the ambient temperature outside the vehicle, the desired temperature (target temperature) set by the driver in the cab, and the air volume. At this time, by controlling the first valve 17 and the second valve 18, the air flow can pass through the evaporator 14 and directly blow into the cab through the air outlet 19 without flowing through the heat storage device 20, so as to reach the target temperature preset by the driver as soon as possible.

[0059] As Figure 2 As shown in the figure, it is a schematic diagram of the structure of the heat storage device 20 in the heat storage mode. At this time:

[0060] When the compressor 12 is in a normal working state and the current temperature in the cab reaches the target temperature, the heat storage device 20 is in the heat storage mode. The positions of the first valve 17 and the second valve 18 are controlled so that the air flowing out of the evaporator 14 passes through the heat storage device 20 and the air outlet 19 respectively, so that the heat storage device 20 stores heat.

[0061] When the cab temperature reaches the comfortable temperature (target temperature) expected by the driver, the positions of the first valve 17 and the second valve 18 can be controlled so that the air flowing out of the evaporator 14 is divided into two parts in the air outlet pipe 21. One part enters the cab through the air outlet 19 to maintain the current temperature in the cab (target temperature), and the other part, under the control of the first valve 17, flows into the heat storage device 20, so that the heat storage device 20 can store a certain amount of heat, and then passes through the outlet end of the heat storage device 20 and enters the cab through the second control valve and the air outlet 19.

[0062] When the heat storage device 20 is in the heat storage mode, without affecting the cab to maintain the target temperature, the energy storage mode can store a part of heat for refrigeration and heating when the vehicle is in a stationary state, and improves the energy utilization rate, having an energy-saving effect.

[0063] As Figure 3 As shown in the figure, it is a schematic diagram of the structure of the heat storage device 20 in the heat release mode. At this time:

[0064] When the compressor 12 is in the off state, the heat storage device 20 is in the heat release mode. Control the positions of the first valve 17 and the second valve 18 so that the incoming air at the air inlet 15 flows into the heat storage device 20, and the heat storage device 20 releases heat to change the temperature of the incoming air.

[0065] When the vehicle stops, in order to save energy consumption, due to mechanical structure constraints, or to reduce noise, the compressor 12 will stop working or operate at a low load. Then, after a certain period of time, the temperature in the cab will no longer meet the comfortable temperature expected by the driver. At this time, the first valve 17 and the second valve 18 can be controlled to allow air to flow through the heat storage device. The heat storage device releases heat, causing the air flowing through the heat storage device to carry away the released heat and flow into the cab through the air outlet 19 to cool or heat the gas in the cab, so as to achieve the comfortable temperature expected by the driver.

[0066] The heat storage device 20 stores a certain amount of heat during the vehicle's driving process and can release the stored heat when the vehicle is stationary and the compressor 12 is not working. This can simplify the structural complexity of the compressor 12 and the electric system, reduce the system cost, reduce the working load of the compressor 12, and reduce the noise when the vehicle is stationary, so as to improve the comfort of the vehicle when it is stationary.

[0067] Embodiment 2

[0068] The embodiment of the present application provides a control method for a vehicle air conditioning device, as Figure 4 shown in the flowchart of the control method for the vehicle air conditioning device, which is applied to the controller in Embodiment 1. The method specifically includes the following steps:

[0069] Step S100: Obtain the working parameters of the compressor 12 to determine the working state of the compressor 12;

[0070] Step S200: Obtain the current temperature in the cab and the preset target temperature;

[0071] Step S300: Based on the working state of the compressor 12, the current temperature in the cab, and the preset target temperature, change the working mode of the heat storage device 20 and control the valve action to switch the air flow path.

[0072] For step S300, when the compressor 12 is in the normal working state, that is, when the vehicle is in the driving state, the compressor 12 operates in the normal refrigeration and heating mode:

[0073] Control the first valve 17 and the second valve 18 so that the air flowing through the evaporator 14 directly passes through the air outlet 19 until the current temperature in the cab reaches the target temperature.

[0074] At this time, by controlling the first valve 17 and the second valve 18, the air at the outlet end of the evaporator 14 is not allowed to pass through the heat storage device 20, so that the cab temperature can reach the target temperature as soon as possible.

[0075] In the heat storage mode:

[0076] When the current cab temperature reaches the target temperature, the heat storage device 20 is in the heat storage mode. Control the positions of the first valve 17 and the second valve 18 so that the air flowing out of the evaporator 14 passes through the heat storage device 20 and the air outlet 19 respectively, so that the heat storage device 20 stores heat.

[0077] Part of the air in the air outlet duct 21 acts directly on the cab, and part of it flows through the energy storage mode for energy storage of the heat storage device 20.

[0078] In the heat release mode:

[0079] When the compressor 12 is in the off state, the heat storage device 20 is in the heat release mode. Control the positions of the first valve 17 and the second valve 18 so that the air entering from the air inlet 15 flows into the heat storage device 20, and the heat storage device 20 releases heat to change the temperature of the incoming air.

[0080] All the air in the air outlet duct 21 flows to the heat storage device 20 to use the heat pre-stored in the heat storage device 20 to change its temperature, so as to realize the refrigeration and heating functions of the cab.

[0081] This method meets the refrigeration and heating requirements of the vehicle in various scenarios, improves the energy utilization rate, has low requirements for the device, and reduces the device complexity and cost.

[0082] The embodiment of the present application also provides an electronic device, which includes a memory and a processor.
