[0060] In the prior art, the blower output power is changed by changing the blower speed or modulating the blower pulse width through pulse width modulation technology, thereby changing the air volume at the air outlet. However, there is a problem of a large error between the actual air volume and the target air volume at the air outlet, and the testing of control parameters requires a lot of manpower and material resources, making it difficult to achieve multi-zone air volume control. To solve the above problems, the present application is conceived to reduce the error between the actual air volume and the target air volume, reduce labor costs and achieve multi-zone air volume control.

[0061] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0062] Figure 1 The present application provides a flowchart of a method for processing air volume in multiple zones of an automobile air conditioner according to an embodiment of the present invention. Figure 1 As shown, the method can be applied in a vehicle. Specifically, the method comprises the following steps:

[0063] Step S101: the air conditioning controller obtains the target air volume and the actual air volume corresponding to each air outlet.

[0064] In this embodiment, when the ambient temperature, the temperature inside the vehicle, and the light intensity are constant, the set temperature and the set air volume gear are manually adjusted, the air volume is tested, and the air volume corresponding to the set temperature and the set air volume gear under the ambient temperature, the temperature inside the vehicle, and the light intensity that makes the human body comfortable is selected as the target air volume. Under different ambient temperatures, temperatures inside the vehicle, and light intensities, the artificially set temperature and the set air volume gear are changed, and the target air volume corresponding to the human body is tested and obtained. A comparison table of ambient temperature, light intensity, temperature inside the vehicle, set temperature, set air volume gear and target air volume is established. According to the comparison table, the target air volume corresponding to each air outlet can be obtained by obtaining the ambient temperature, temperature inside the vehicle, light intensity, set temperature, and set air volume gear.

[0065] In this embodiment, the actual total air volume is obtained based on the mode damper opening, the temperature damper opening, the internal and external circulation damper opening and the blower speed, the branch resistance of each air outlet is obtained based on the mode damper opening and the temperature damper opening, and the actual air volume corresponding to each air outlet is obtained based on the actual total air volume and the branch resistance of each air outlet.

[0066] Step S102: The air conditioning controller obtains the branch resistance corresponding to each air outlet, and obtains the blower speed that matches when the actual air volume corresponding to the air outlet reaches the corresponding target air volume based on the target air volume, actual air volume and branch resistance corresponding to the air outlet.

[0067] Step S103: The air conditioning controller determines the air outlet corresponding to the maximum blower speed from the blower speeds matched to each air outlet, so as to select the air outlet as the pre-selected air outlet.

[0068] Step S104: the air conditioning controller adjusts the blower speed according to the maximum blower speed, and controls the opening of the mode damper corresponding to the pre-selected air outlet to 100%.

[0069] Step S105: The air conditioning controller adjusts the opening of the mode damper corresponding to each air outlet except the pre-selected air outlet according to the target air volume and actual air volume corresponding to the air outlet and the adjusted blower speed.

[0070] In this embodiment, the target air volume and actual air volume corresponding to each air outlet are obtained by the air-conditioning controller; the air-conditioning controller obtains the branch resistance corresponding to each air outlet, and obtains the blower speed that matches the actual air volume corresponding to the air outlet when the corresponding target air volume reaches the corresponding target air volume based on the target air volume, actual air volume and branch resistance corresponding to the air outlet; the air-conditioning controller determines the air outlet corresponding to the maximum blower speed from the blower speeds matched by each air outlet, so as to use the air outlet as the preselected air outlet; the air-conditioning controller adjusts the blower speed according to the maximum blower speed, and controls the opening of the mode damper corresponding to the preselected air outlet to 100%; for each air outlet other than the preselected air outlet, the air-conditioning controller adjusts the opening of the mode damper corresponding to the other air outlets according to the target air volume and actual air volume corresponding to the air outlet and the adjusted blower speed. Compared with the prior art which changes the blower output power by changing the blower speed or by modulating the blower pulse width through pulse width modulation technology, thereby changing the air volume at the air outlet, the present application selects a pre-selected air outlet, determines the blower speed, controls the opening of the mode damper corresponding to the pre-selected air outlet to 100%, and adjusts the opening of the mode damper of other air outlets according to the target air volume, the actual air volume and the adjusted blower speed, so that the actual air volume of each air outlet is close to the target air volume, and reduces the error between the actual air volume and the target air volume through closed-loop control of the air volume, thereby realizing multi-zone air volume control, avoiding setting parameters, and reducing labor costs.

[0071] Figure 2 The flowchart of the second embodiment of the method for processing multi-zone air volume of an air conditioner based on an automobile provided in the present application is as follows: Figure 2 As shown, the method can be applied in a vehicle. Specifically, the method comprises the following steps:

[0072] Step S201: The air conditioning controller obtains the current air volume level and set temperature, and obtains the temperature inside the vehicle and the ambient temperature of the vehicle.

[0073] Step S202: Obtain the target air volume corresponding to each air outlet according to the current air volume level, the set temperature, the temperature inside the car, and the ambient temperature of the car.

[0074] In this embodiment, the air conditioning controller can also obtain the light intensity in the car, and obtain the target air volume corresponding to each air outlet according to the current air volume level, set temperature, temperature in the car, ambient temperature of the car, and light intensity.

[0075] In this embodiment, when the ambient temperature, the temperature inside the vehicle, and the light intensity are constant, the set temperature and the set air volume gear are manually adjusted, the air volume is tested, and the air volume corresponding to the set temperature and the set air volume gear under the ambient temperature, the temperature inside the vehicle, and the light intensity is selected as the target air volume. Under different ambient temperatures, the temperatures inside the vehicle, and the light intensity, the artificially set temperature and the set air volume gear are changed, and the target air volume corresponding to the human body is tested and obtained. A comparison table of ambient temperature, vehicle temperature, light intensity, set temperature, set air volume gear and target air volume is established. According to the comparison table, the target air volume corresponding to each air outlet can be obtained by obtaining the ambient temperature, vehicle temperature, light intensity, set temperature, and set air volume gear.

[0076] Specifically, Figure 3 As shown in the principle diagram of the target air volume of each air outlet, the target air volume corresponding to each air outlet is calculated based on the ambient temperature, the temperature inside the vehicle, the light intensity, the set temperature, and the set air volume gear.

[0077] Step S203: the air conditioning controller obtains the total air volume according to the opening of the mode damper and the opening of the temperature damper corresponding to each air outlet, the opening of the internal and external circulation damper, and the blower speed.

[0078] Step S204: the air conditioning controller obtains the actual air volume corresponding to each air outlet according to the total air volume and the branch resistance corresponding to the air outlet.

[0079] Specifically, Figure 4 As shown in the principle diagram of the actual air volume at each air outlet, the actual total air volume is obtained based on the opening of the mode air door, i.e. the position of the mode air door motor, the opening of the temperature air door, i.e. the position of the temperature air door motor, the opening of the internal and external circulation air door, i.e. the position of the internal and external circulation air door motor, and the blower speed. The branch resistance of each air outlet is obtained based on the opening of the mode air door, i.e. the position of the mode air door motor, and the opening of the temperature air door, i.e. the position of the temperature air door motor. The actual air volume of each air outlet is obtained based on the actual total air volume and the branch resistance corresponding to each air outlet.

[0080] Step S205: The air conditioning controller obtains the branch resistance corresponding to each air outlet, and obtains the blower speed that matches when the actual air volume corresponding to the air outlet reaches the corresponding target air volume based on the target air volume, actual air volume and branch resistance corresponding to the air outlet.

[0081] Step S206: The air conditioning controller determines the air outlet corresponding to the maximum blower speed from the blower speeds matched to each air outlet, so as to select the air outlet as the pre-selected air outlet.

[0082] Step S207: the air conditioning controller adjusts the blower speed according to the maximum blower speed, and controls the opening of the mode damper corresponding to the pre-selected air outlet to 100%.

[0083] Step S208: For each of the other air outlets, obtain the difference between the target air volume and the actual air volume corresponding to the air outlet, and query the mapping relationship between the air volume, speed and mode damper opening, and obtain the mode damper opening that matches the difference and the adjusted speed of the blower, so as to adjust the opening of the mode damper corresponding to the air outlet according to the matching mode damper opening.

[0084] Specifically, Figure 5 As shown in the control principle diagram of the mode damper and the blower, according to the opening of the mode damper, i.e., the position of the mode damper motor, the opening of the temperature damper, i.e., the position of the temperature damper motor, and the target air volume of each air outlet, the air outlet with the largest mode damper opening is obtained when the blower speed is constant and the actual air volume is equal to the target air volume, and the air outlet is used as the pre-selected air outlet; when the opening of the mode damper corresponding to the pre-selected air outlet is 100%, according to the target air volume and the actual air volume of each air outlet, the target air volume and the actual air volume of the pre-selected air outlet are obtained, and the pre-selected air outlet is obtained. When the opening of the mode damper of the selected air outlet is 100%, the target air volume is equal to the blower speed corresponding to the actual air volume, and this speed is used as the blower target speed, so that the blower speed reaches the blower target speed, and the opening of the mode damper of the pre-selected air outlet is maintained at 100%; for other air outlets, according to the difference between the corresponding target air volume and the actual air volume, and the mapping relationship between the air volume, speed and mode damper opening is queried, and according to the proportional-integral adjustment method, the mode damper is adjusted to make the actual air volume equal to the target air volume.

[0085] The principle of the multi-zone air volume processing system based on automobile air conditioning is as follows Figure 6As shown in the principle structure diagram of a multi-zone air volume processing system for air conditioning based on a car, the air conditioning controller is connected with an ambient temperature sensor, a light intensity sensor, an in-car temperature sensor, a blower speed sensor, an internal and external circulation damper motor, a temperature damper motor, a mode damper motor, a human-computer interaction interface and a blower, wherein the ambient temperature sensor monitors the ambient temperature, the light intensity sensor monitors the light intensity, the in-car temperature sensor monitors the in-car temperature, the blower speed sensor feeds back the blower speed in real time, the internal and external circulation damper motor controls the internal and external circulation damper opening, and the temperature damper motor controls the temperature damper Opening, mode damper motor controls mode damper opening, human-computer interaction interface inputs manually set temperature and air volume gear, the blower controls the blower speed according to the ambient temperature, light intensity, temperature in the car, internal and external circulation damper opening, temperature damper opening, mode damper opening, manually set temperature and air volume gear, adjusts the blower speed so that the blower speed meets the preset outlet mode damper opening of 100% and the actual air volume is equal to the target air volume. During the adjustment process, the blower speed is fed back in real time through the blower speed sensor, and the blower speed is adjusted according to the actual air volume and the target air volume.

[0086] In this embodiment, the target air volume and actual air volume corresponding to each air outlet are obtained through the air-conditioning controller; the pre-selected air outlet is selected, the blower speed is determined, and the opening of the mode air door corresponding to the pre-selected air outlet is controlled to be 100%. For other air outlets, the opening of their mode air doors is adjusted according to the target air volume and the actual air volume and the adjusted blower speed, so that the actual air volume of each air outlet is equal to the target air volume. The error between the actual air volume and the target air volume is reduced through closed-loop control of the air volume, thereby realizing multi-zone air volume control, avoiding setting parameters, and reducing labor costs.
