[0025] As introduced in the background technology, the prior art vehicle air conditioner has the problem of high power consumption. To solve the problem of high power consumption of the prior art vehicle air conditioner, the embodiments of the present application provide an energy-saving control system, an energy-saving control method, an energy-saving control device, a computer-readable storage medium and an air conditioner for a vehicle air conditioner.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] This embodiment provides an energy-saving control system for a vehicle air conditioner, such as Figure 1 As shown, including:

[0028] Car air conditioner outdoor unit 10;

[0029] Specifically, for split-type car air conditioners, the car air conditioner internal unit is usually in the cab, and the car air conditioner external unit is suspended behind the cab, so there is enough space to install the air intake duct. The assembled duct is placed on the left side of the car air conditioner external unit, extending upward to the roof, with the air inlet facing forward, so that there will be the largest windward area and air intake.

[0030] The air inlet duct 20 includes an air duct 21, an air inlet 22 and a wind speed detector. The air inlet 22 is installed above the vehicle cab 30. The wind speed detector is installed at the air inlet 22. The air inlet 22 is connected to the vehicle air conditioner outdoor unit 10 through the air duct 21. During the driving of the vehicle, the wind collected by the air inlet 22 is guided to the fan of the vehicle air conditioner outdoor unit 10 through the air duct 21.

[0031] This embodiment adds an air intake duct to the vehicle air conditioner outdoor unit to guide the air on the top of the vehicle to the inside of the vehicle air conditioner outdoor unit. The outdoor fan can be driven to rotate without powering on the outdoor fan to complete the heat exchange on one side of the air conditioner condenser, which can not only ensure the normal operation and heat exchange of the air conditioner, but also achieve energy-saving effects. This solves the problem of high power consumption of the vehicle air conditioner in the prior art.

[0032] In the specific implementation process, Figure 1 As shown, the air inlet duct 20 further includes a filter 23 , and the filter 23 is installed at the air inlet 22 .

[0033] The system installs a filter at the air inlet to prevent leaves, garbage and other debris from being blown into the air inlet duct, and installs a wind speed detector at the air inlet of the air inlet duct. The entire air inlet duct is attached to the outer wall of the cab and fixed at the same time.

[0034] In this embodiment, an energy-saving control method running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0035] Figure 2 is a flow chart of an energy-saving control method according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0036] Step S201, when the vehicle is traveling and the vehicle air conditioner is in operation, obtaining the wind speed at the air inlet, wherein the wind speed at the air inlet is collected by a wind speed detector;

[0037] Specifically, when the indoor unit of the car air conditioner receives a power-on command and sets the cooling mode, when the outdoor unit of the car air conditioner starts and runs stably, the wind speed detector at the air inlet of the duct starts working, detects the wind speed at the air inlet, and compares it with the fan speed of the outdoor unit of the car air conditioner after stabilization.

[0038] Step S202, obtaining the fan speed of the above-mentioned vehicle air-conditioning outdoor unit, and controlling the operation of the above-mentioned fan of the above-mentioned vehicle air-conditioning outdoor unit according to the above-mentioned fan speed and the above-mentioned air inlet wind speed.

[0039] Through this embodiment, when the vehicle is driving and the vehicle air conditioner is in operation, the air inlet wind speed is obtained, wherein the air inlet wind speed is collected by a wind speed detector; the fan speed of the vehicle air conditioner outdoor unit is obtained, and the fan operation of the vehicle air conditioner outdoor unit is controlled according to the fan speed and the air inlet wind speed. By guiding the wind collected at the air inlet to the fan of the vehicle air conditioner outdoor unit through the air duct, the fan operation of the vehicle air conditioner outdoor unit is adjusted according to the fan speed and the air inlet wind speed, and the heat exchange on one side of the condenser of the vehicle air conditioner outdoor unit is completed, the normal operation and heat exchange of the air conditioner can be ensured, and energy-saving effect can also be achieved. The problem of high power consumption of the vehicle air conditioner in the prior art is solved.

[0040] During the specific implementation process, the operation of the fan of the vehicle air-conditioning outdoor unit is controlled according to the fan speed and the air inlet wind speed, including: when it is determined that the air inlet wind speed is less than the fan speed, keeping the operating speed of the fan unchanged; when it is determined that the air inlet wind speed is equal to the fan speed, controlling the operating speed of the fan to be reduced to a first preset speed; when it is determined that the air inlet wind speed is greater than the fan speed, controlling the operating speed of the fan to be reduced to a second preset speed, wherein the second preset speed is less than the first preset speed.

[0041] The first preset rotation speed may be set to two-thirds of the original fan rotation speed, and the second preset rotation speed may be set to one-third of the original fan rotation speed.

[0042] In this method, when the wind speed at the air inlet is less than the fan speed, it means that the vehicle speed is low and the air in front of the vehicle cannot flow into the duct quickly, which is not helpful for the heat exchange of the outdoor unit. At this time, the outdoor fan runs at the existing speed; when the wind speed at the air inlet is equal to or greater than the fan speed, it means that the vehicle has a high driving speed and the air in front of the vehicle can rush into the duct quickly to meet the requirements of auxiliary heat exchange. Therefore, the fan speed is adjusted to achieve the purpose of air conditioning energy saving.

[0043] Specifically, the operation of the fan of the vehicle air-conditioning outdoor unit is controlled according to the fan speed and the air inlet wind speed, including: when it is determined that the air inlet wind speed decreases from greater than the fan speed to equal to the fan speed, controlling the operation speed of the fan to increase to a third preset speed; when it is determined that the air inlet wind speed decreases from greater than the fan speed to less than the fan speed, controlling the operation speed of the fan to increase to a fourth preset speed, wherein the fourth preset speed is greater than the third preset speed.

[0044] The third preset speed may be set to three quarters of the original fan speed, and the fourth preset speed may be set to three fifths of the original fan speed.

[0045] The method increases the fan speed by one third of the fan speed when the air inlet wind speed decreases from greater than the fan speed to equal to the fan speed; and increases the fan speed by two thirds of the fan speed when the air inlet wind speed decreases from greater than the fan speed to less than the fan speed. In this way, the cooling efficiency of the air conditioner can be maintained when the vehicle speed decreases, avoiding the problem of poor heat exchange efficiency of the air conditioner outdoor unit due to reduced vehicle speed.

[0046] More specifically, the operation of the fan of the vehicle air-conditioning outdoor unit is controlled according to the fan speed and the air inlet wind speed, including: constructing a mapping relationship table between the operating power of the vehicle air-conditioning outdoor unit and the air inlet wind speed and the fan speed; and adjusting the operating speed of the fan of the vehicle air-conditioning outdoor unit according to the mapping relationship table.

[0047] The method can convert the operating power of the outdoor unit of the vehicle air conditioner into the required speed of the outdoor unit fan, and then determine the final fan speed by the speed difference between the collected air inlet wind speed and the required speed of the outdoor unit fan, and then construct a mapping relationship table of the operating power of the outdoor unit of the vehicle air conditioner and the air inlet wind speed and fan speed based on historical data, and accurately adjust the fan speed of the outdoor unit through the mapping relationship table.

[0048] Furthermore, the above method also includes: when the vehicle is driving and the vehicle air conditioner is in operation, determining the operation mode of the above vehicle air conditioner; when it is determined that the above operation mode of the above vehicle air conditioner is a cooling mode, controlling the above wind speed detector to collect the above air inlet wind speed.

[0049] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the energy-saving control method of the present application will be described in detail below in combination with specific embodiments.

[0050] This embodiment relates to a specific energy-saving control method, such as Figure 3 As shown, including the following:

[0051] When the indoor unit receives the power-on command and sets the cooling mode, the fan of the outdoor unit of the vehicle air conditioner starts and runs stably. At this time, the wind speed detector at the air inlet of the air inlet duct starts to work, detects the wind speed at the air inlet, and compares it with the fan speed of the outdoor unit of the vehicle air conditioner after stabilization:

[0052] When the air inlet speed is lower than the fan speed, it means that the vehicle speed is low and the air in front of the vehicle cannot flow into the duct quickly, which is not helpful for the heat exchange of the outdoor unit. At this time, the outdoor fan runs at the existing speed;

[0053] When the wind speed at the air inlet is equal to the fan speed, it means that the vehicle is at a relatively high speed, and the air in front of the vehicle can quickly rush into the air duct to meet the requirements of auxiliary heat exchange. At this time, the fan speed of the outdoor unit of the vehicle air conditioner is reduced by one third, and the duct air supply assists heat exchange;

[0054] When the wind speed at the air inlet is greater than the fan speed, it means that the vehicle is traveling at a very high speed. The air flow rate in front of the vehicle can have a good heat exchange effect. At this time, the fan speed of the vehicle air conditioner outdoor unit is reduced by two-thirds to achieve the purpose of energy saving.

[0055] Reverse logic: when the wind speed at the air inlet changes from greater than the fan speed to equal to the fan speed, the fan speed of the outdoor unit of the car air conditioner increases by one third; when the wind speed at the air inlet is less than the fan speed, the fan speed of the outdoor unit of the car air conditioner runs according to the original program setting speed.

[0056] This embodiment adds an air intake duct to the vehicle air conditioner outdoor unit to guide the air on the top of the vehicle to the inside of the vehicle air conditioner outdoor unit. The outdoor fan can be driven to rotate without powering on the outdoor fan to complete the heat exchange on one side of the air conditioner condenser, which can not only ensure the normal operation and heat exchange of the air conditioner, but also achieve energy-saving effects. This solves the problem of high power consumption of the vehicle air conditioner in the prior art.

[0057] The embodiment of the present application also provides an energy-saving control device. It should be noted that the energy-saving control device of the embodiment of the present application can be used to execute the energy-saving control method provided by the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions have been made without further details. As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0058] The following is an introduction to the energy-saving control device provided in the embodiments of the present application.

[0059] Figure 4 Schematic diagram of an energy-saving control device according to an embodiment of the present application. Figure 4 As shown, the device comprises:

[0060] The acquisition unit 41 is used to acquire the wind speed at the air inlet when the vehicle is traveling and the vehicle air conditioner is in operation, wherein the wind speed at the air inlet is acquired by a wind speed detector;

[0061] Specifically, when the indoor unit of the car air conditioner receives a power-on command and sets the cooling mode, when the outdoor unit of the car air conditioner starts and runs stably, the wind speed detector at the air inlet of the duct starts working, detects the wind speed at the air inlet, and compares it with the fan speed of the outdoor unit of the car air conditioner after stabilization.

[0062] The first control unit 42 is used to obtain the fan speed of the above-mentioned vehicle air-conditioning outdoor unit, and control the operation of the above-mentioned fan of the above-mentioned vehicle air-conditioning outdoor unit according to the above-mentioned fan speed and the above-mentioned air inlet wind speed.

[0063] In this embodiment, the air collected at the air inlet is directed to the fan of the vehicle air conditioner outdoor unit through the air duct, and the fan operation of the vehicle air conditioner outdoor unit is adjusted according to the fan speed and the air inlet wind speed, so as to complete the heat exchange on one side of the condenser of the vehicle air conditioner outdoor unit, which can not only ensure the normal operation and heat exchange of the air conditioner, but also have an energy-saving effect. This solves the problem of high power consumption of the vehicle air conditioner in the prior art.

[0064] As an optional scheme, the first control unit includes a maintaining module, a first control module and a second control module; the maintaining module is used to maintain the operating speed of the above-mentioned fan unchanged when it is determined that the above-mentioned air inlet wind speed is less than the above-mentioned fan speed; the first control module is used to control the operating speed of the above-mentioned fan to be reduced to a first preset speed when it is determined that the above-mentioned air inlet wind speed is equal to the above-mentioned fan speed; the second control module is used to control the operating speed of the above-mentioned fan to be reduced to a second preset speed when it is determined that the above-mentioned air inlet wind speed is greater than the above-mentioned fan speed, wherein the above-mentioned second preset speed is less than the above-mentioned first preset speed.

[0065] Among them, the first preset speed can be set to two-thirds of the original fan speed, and the second preset speed can be set to one-third of the original fan speed. Specifically, when the wind speed at the air inlet is less than the fan speed, it means that the vehicle speed is low at this time, and the air in front of the front of the vehicle cannot flow into the duct quickly, which is not helpful for the heat exchange of the outdoor unit. At this time, the outdoor fan runs at the existing speed; when the wind speed at the air inlet is equal to or greater than the fan speed, it means that the vehicle has a high driving speed at this time, and the air in front of the front of the vehicle can rush into the duct quickly to meet the requirements of auxiliary heat exchange, so the fan speed is adjusted to achieve the purpose of air conditioning energy saving.

[0066] In an optional scheme, the first control unit also includes a third control module and a fourth control module; the third control module is used to control the operating speed of the fan to increase to a third preset speed when it is determined that the wind speed at the air inlet has decreased from greater than the fan speed to equal to the fan speed; the fourth control module is used to control the operating speed of the fan to increase to a fourth preset speed when it is determined that the wind speed at the air inlet has decreased from greater than the fan speed to less than the fan speed, wherein the fourth preset speed is greater than the third preset speed.

[0067] The third preset speed may be set to three quarters of the original fan speed, and the fourth preset speed may be set to three fifths of the original fan speed.

[0068] Specifically, when the wind speed at the air inlet decreases from greater than the fan speed to equal to the fan speed, the fan speed is increased by one third of the fan speed; when the wind speed at the air inlet decreases from greater than the fan speed to less than the fan speed, the fan speed is increased by two thirds of the fan speed. In this way, the cooling efficiency of the air conditioner can be maintained when the vehicle speed decreases, avoiding the problem of poor heat exchange efficiency of the air conditioner outdoor unit due to reduced vehicle speed.

[0069] An optional solution, the first control unit also includes a construction module and an adjustment module; the construction module is used to construct a mapping relationship table between the operating power of the above-mentioned vehicle air-conditioning outdoor unit and the above-mentioned air inlet wind speed and the above-mentioned fan speed; the adjustment module is used to adjust the above-mentioned operating speed of the above-mentioned fan of the above-mentioned vehicle air-conditioning outdoor unit according to the above-mentioned mapping relationship table.

[0070] Specifically, the operating power of the outdoor unit of the vehicle air conditioner can be converted into the required speed of the outdoor fan, and then the final fan speed can be determined by the speed difference between the collected air inlet wind speed and the required speed of the outdoor fan. Then, based on historical data, a mapping relationship table of the operating power of the outdoor unit of the vehicle air conditioner and the air inlet wind speed and fan speed can be constructed, and the fan speed of the outdoor unit can be accurately adjusted through the mapping relationship table.

[0071] In an optional scheme, the device also includes a determination unit and a second control unit; the determination unit is used to determine the operating mode of the above-mentioned vehicle air conditioner when the vehicle is driving and the vehicle air conditioner is in operation; the second control unit is used to control the above-mentioned wind speed detector to collect the above-mentioned air inlet wind speed when it is determined that the above-mentioned operating mode of the above-mentioned vehicle air conditioner is a cooling mode.

[0072] The energy-saving control device includes a processor and a memory. The acquisition unit and the first control unit are stored in the memory as program units, and the processor executes the program units stored in the memory to implement corresponding functions. The modules are all located in the same processor; or, the modules are located in different processors in any combination.

[0073] The processor includes a kernel, and the kernel calls the corresponding program unit from the memory. One or more kernels can be set, and the problem of large power consumption of the existing vehicle air conditioner can be solved by adjusting the kernel parameters.

[0074] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.
