[0059] See also Figures 1 to 11 As shown, according to an embodiment of this application, a parking air conditioning energy-saving component includes:

[0060] The bracket 1 includes an air duct and a mounting surface; the air inlet 11 of the air duct is located on an adjacent or opposite side of the mounting surface and faces the vehicle's direction of travel; the first air outlet of the air duct is located on the mounting surface.

[0061] The mounting surface is inclined relative to the vehicle's direction of travel; the mounting surface is used to assemble the outdoor unit 3 of the parking air conditioner.

[0062] This application utilizes the airflow generated by vehicle operation, and uses a bracket to guide the airflow to the outdoor unit 3 of the parking air conditioner, so as to remove the heat from the outdoor unit 3 by air cooling, thereby reducing the energy consumption of the outdoor unit 3 fan 31 and saving energy.

[0063] The air duct guides the direction of airflow, with its air inlet 11 facing the direction of vehicle movement. This ensures that the air generated by the vehicle's movement enters the air duct through the air inlet 11 and then flows out through the first air outlet.

[0064] The mounting surface is set at an angle, so that the outdoor unit 3 installed on it will be subject to airflow. In this way, the components in the outdoor unit 3 that need heat dissipation, such as the condenser 32, will be partially carried away by the airflow from the air duct, thereby reducing the wear and tear on the fan 31 in the outdoor unit 3 or achieving the cooling effect more quickly.

[0065] In some implementations...

[0066] The air duct also includes a second air outlet 12, which has at least one outlet and is located on the remaining side away from the air inlet.

[0067] A second air outlet 12 is installed on the remaining side of the bracket 1 away from the air inlet to avoid airflow resistance that could affect vehicle operation. Part of the airflow entering from the air inlet 11 passes through the outdoor unit 3 to achieve auxiliary cooling and energy saving, while the other part is discharged from the second air outlet 12 to ensure smooth airflow in the duct.

[0068] In some implementations...

[0069] The bracket 1 includes at least two side-by-side spaced support ribs, which are laid flat along the vehicle's direction of travel, and the air inlet 11 is formed between adjacent support ribs; the top surface of the support rib is the mounting surface; a groove is provided on the top surface, and the groove forms the second air outlet 12.

[0070] The bracket 1 can specifically adopt two side-by-side support ribs, with the two support ribs spaced apart and the gap in the middle forming an air duct. Since the top surface of the support ribs is an inclined mounting surface, it is convenient to install the outdoor unit 3 of the parking air conditioner, so that the outdoor unit 3 is installed at an angle. The bottom surface of the outdoor unit 3 is the side wall of the air duct. In actual assembly, the bottom surface of the outdoor unit 3 is the condenser 32, and the fan 31 is above the condenser 32. In this way, the condenser 32 comes into contact with the airflow in the air duct, and the airflow carries away the heat on the condenser 32, thereby reducing the energy consumption of the fan 31 and saving energy.

[0071] A groove is provided on the top surface to form the second air outlet 12, which facilitates airflow and carries away the heat of the condenser from the side, thus accelerating the heat dissipation speed.

[0072] In some implementations...

[0073] The air inlet 11 is equipped with a control component for adjusting the airflow rate entering the air duct.

[0074] A control element is installed at the air inlet 11 to adjust the air intake volume. This adjustment can be linked to the operation of the fan 31 to achieve automated energy-saving effects. For example, when the air volume is large, the fan speed of the fan 31 is reduced; when the air volume is small, the fan speed of the fan 31 is increased.

[0075] In some implementations...

[0076] The control component includes at least one of a damper 2 and a fan; the damper 2 is rotatably mounted on the side of the air inlet 11, and the fan is mounted in the air inlet 11.

[0077] The control unit includes at least one of a damper 2 and a fan. Opening or closing the damper 2 can change the air volume entering the air duct, and changing the fan speed can also change the air volume entering the air duct.

[0078] In some implementations...

[0079] The damper 2 is configured as a baffle that is freely rotatably hung on the air inlet 11. The rotation of the baffle corresponds to the airflow rate through the air inlet 11. When the airflow rate exceeds a preset value, the baffle rotates under the action of the airflow to open the air inlet 11, and the opening of the air inlet 11 increases with the increase of the airflow rate.

[0080] In specific settings, the damper 2 is a baffle structure that can be freely rotated and suspended above the air inlet 11. When the vehicle is not running, the baffle blocks the air inlet 11. When the vehicle is running, if the airflow exceeds the preset value, the damper 2 can be pushed open to enter the air duct.

[0081] At this time, the degree to which damper 2 is opened is directly proportional to the airflow rate.

[0082] According to another aspect of this application, a parking air conditioner is provided, including the parking air conditioner energy-saving component as described above.

[0083] The parking air conditioner of this application uses the aforementioned energy-saving components, which can reduce the energy consumption of the fan 31 and save energy.

[0084] According to another aspect of this application, a method for controlling a parking air conditioner as described above is provided, comprising:

[0085] Detect the wind speed at the air inlet 11;

[0086] The rotational speed of the fan 31 in the outdoor unit 3 is adjusted according to the wind speed.

[0087] The wind speed and the rotation speed are set inversely proportional.

[0088] This application adjusts the rotation speed of the fan 31 by detecting the wind speed entering the air duct through the air inlet 11, and the two are inversely proportional, that is, when the wind speed is high, the rotation speed of the fan 31 decreases, and when the wind speed is low, the rotation speed of the fan 31 increases.

[0089] In some implementations...

[0090] An air inlet 11 is provided with an air damper 2, and an additional number of detection devices 4 are provided at the air inlet 11, arranged sequentially along the rotation direction of the air damper 2, for detecting the rotation angle of the air damper 2.

[0091] Detecting the wind speed at the air inlet 11 includes detecting the rotation angle of the damper 2; the rotation angle corresponds to the speed setting of the fan 31.

[0092] When a damper 2 is installed at the air inlet 11, multiple detection devices 4 are installed on the air inlet 11 to detect the rotation angle of the damper 2, that is, the opening degree of the damper 2.

[0093] When the car is running, the damper 2 will rotate around the pivot 21 due to the airflow. The angle of rotation is related to the airflow volume. The greater the airflow volume, the more the damper 2 is blown up, i.e., the larger the angle. Conversely, the smaller the airflow volume, the less the damper 2 is blown up, i.e., the smaller the angle.

[0094] The bracket 1 is equipped with evenly distributed detection devices 4 along the rotation direction of the damper 2; these devices can detect the angle at which the damper 2 is blown up; and then determine how much the fan speed of the fan 31 is reduced based on the size of the angle at which the damper 2 is blown up. The larger the angle, the greater the air volume entering the condenser 32, meaning the fan speed of the fan 31 drops more; the smaller the angle, the smaller the air volume entering the condenser 32, meaning the fan speed of the fan 31 drops less, thus achieving energy saving for the fan 31.

[0095] To eliminate misjudgments, after the detection device 4 detects the specific angle at which the damper 2 is opened, it needs to wait for a period of time to stabilize before determining the specific angle, and then feeding back to the main control system to reduce the speed of the fan 31 accordingly.

[0096] The detection device 4 can be a light detector, with a light emitter and a light sensor positioned at corresponding positions on the two brackets 1. When the baffle rotates, it will inevitably block the light, and the light sensor will not receive light, thus determining the rotation angle of the damper 2. Alternatively, it can be a magnetic induction sensor, with a magnetic strip placed on the side of the damper 2. When the damper 2 rotates to a certain position, the magnetic induction sensor at that position senses the magnetic force, thus determining the rotation angle. Such detection devices 4 for detecting the rotation angle of the damper 2 are common in conventional technologies and will not be described in detail here.

[0097] In some implementations...

[0098] When the damper 2 is rotated to the position of any of the detection devices 4 and maintained for a preset time, the speed of the fan 31 is reduced to the corresponding level.

[0099] Specific control methods may include:

[0100] When outdoor unit 3 is running, its internal fan 31 is running, and the air conditioner starts operating during time period T0.

[0101] There are multiple detection devices 4 on the bracket 1, which are evenly distributed along the rotation direction of the damper 2 and can be set as four locations: A, B, C, and D. When the damper 2 rotates to the corresponding position, it can be detected, thus monitoring the opening angle of the damper 2 in real time. Among them, A, B, C, and D can be specific locations or area values.

[0102] 1) When the damper 2 opens to angle A, the corresponding detection device 4A reacts and detects it; the device continues to detect during the t0 time period and responds; this is determined to be the first state: the damper of the fan 31 is reduced by one level;

[0103] 2) When the damper 2 opens to angle B, the corresponding detection device 4B reacts and detects it; the device continues to detect during the t0 time period and responds; it is determined to be the second state: the damper of the fan 31 is reduced by two levels;

[0104] 3) When the damper 2 opens to angle C, the corresponding detection device 4C reacts and detects it; the device continues to detect during the t0 time period and responds; it is determined to be the third state: the fan 31 damper is reduced by three levels;

[0105] 4) When the damper 2 opens to angle D, the corresponding detection device 4D reacts and detects it; the device continues to detect during the t0 time period and responds; it is determined to be the fourth state: the fan 31 damper is reduced by four levels;

[0106] The air conditioner is running and continuously monitored, with the monitoring cycle being the t0 time period.

[0107] Switching between states:

[0108] The windshield upshift and downshift positions differ by one gear between each state:

[0109] For example: Case 1) If the previous stage was the first state, and after time period t0 it is determined to be the third state; then the windshield of fan 31 will be reduced by two levels.

[0110] Case 2) If the previous stage was the fourth state, and after the t0 time period, it is determined to be the second state; then the windshield of fan 31 needs to be increased by two levels for compensation.

[0111] Case 3) When the damper 2 is closed, the fan 31 remains unchanged and the damper does not need to be raised or lowered.

[0112] Special case determination:

[0113] If all three detection devices 4 respond within three adjacent intervals of time period t0, then it is necessary to determine the duration of each interval; the interval with the longest duration is then determined as the operating status corresponding to that interval.

[0114] In some implementations...

[0115] A fan is installed at the air inlet 11;

[0116] Detecting the wind speed at the air inlet 11 includes detecting the rotational speed of the fan; the rotational speed corresponds to the speed setting of the fan 31.

[0117] When the car is running, the fan rotates due to the airflow. The rotation speed is related to the air volume; the greater the air volume, the faster the fan rotates, and vice versa. The speed at which the fan 31 is reduced is determined by the fan rotation speed. A faster fan speed indicates a larger airflow entering the condenser 32, meaning a greater reduction in the fan 31's speed; a slower fan speed indicates a smaller airflow entering the condenser 32, meaning a smaller reduction in the fan 31's speed, thus achieving energy savings for the fan 31.

[0118] Control method:

[0119] Outdoor unit 3 is running, outdoor fan 31 is running, and the air conditioner starts operating during time period T0.

[0120] A fan is mounted and fixed on bracket 1; the fan speed is monitored in real time.

[0121] 1) When the fan speed reaches A, there is a response throughout the continuous monitoring period t0.

[0122] Status 1: Fan 31 windshield reduced by one level;

[0123] 2) When the fan speed reaches B, a response is continuously detected throughout the t0 time period.

[0124] Status 2: Fan 31 windshield reduced by two levels;

[0125] 3) When the fan speed reaches C, a response is continuously detected throughout the t0 time period.

[0126] The condition is determined to be state 3: the fan 31 windshield is reduced by three levels;

[0127] 4) When the fan speed reaches D, a response is continuously detected throughout the t0 time period.

[0128] Status 4: Fan 31 windshield reduced by four levels;

[0129] The air conditioner is running and continuously monitored, with the monitoring cycle being the t0 time period.

[0130] Switching between states:

[0131] The windshield upshift and downshift positions differ by one gear between each state:

[0132] For example: Case 1) The previous stage was state 1, and after time period t0, it is determined to be state 3; then the windshield of fan 31 is reduced by two levels.

[0133] Case 2) If the previous stage was state 4, and after time period t0, it is determined to be state 2; then the windshield of fan 31 needs to be increased by two levels for compensation.

[0134] Case 3) When the fan is not running, the fan 31 remains unchanged, and the windshield does not need to be raised or lowered.

[0135] Special case determination:

[0136] If all three adjacent intervals in time period t0 have a response, then the duration of each interval needs to be determined; the interval with the longest duration is then determined as the operating state corresponding to that interval.

[0137] In actual operation, the current value generated by the fan rotation can also be used to determine the direction of operation.
