A control method of a vehicle-mounted ceiling-mounted type air conditioner according to an embodiment of the present invention will be described with reference to fig. 4 with continued reference to fig. 1 to 3. Fig. 4 is a detailed step diagram of a control method of a vehicle-mounted ceiling-mounted air conditioner according to an embodiment of the present invention.
Referring to fig. 4, the gears of the vehicle include n forward gears including 1 gear, 2 gear, … gear and n gear, and the control method of the vehicle-mounted overhead air conditioner includes the following steps:
and S100, acquiring the current gear of the vehicle.
Step S210, calculating a target opening degree of the air outlet according to a formula K ═ n +1-i)/n according to the current gear of the vehicle, where K is the target opening degree of the air outlet, and i is a forward gear of the vehicle.
Since a negative pressure region is formed above the roof panel 11 during the driving of the vehicle, the generated negative pressure will promote the wind out of the first wind outlet 131 and the second wind outlet 132. Typically, a domestic vehicle includes five forward gears, 1, 2, 3, 4 and 5, and each gear corresponds generally to a range of speeds, with the speeds increasing relatively from 1 to 5. The greater the speed of the vehicle, the greater the relative movement speed of the on-board air conditioner and the air, and the greater the influence of the airflow generated by the relative movement on the airflow velocity of the first air outlet 131 and the second air outlet 132. When the gear of the vehicle includes five forward gears, n is 5, and the target opening degrees of the first and second outlets 131 and 132 are calculated according to the formula K ═ 6-i)/5. That is, when the current gear i of the vehicle is 1, 2, 3, 4, 5, the target opening degrees of the first outlet 131 and the second outlet 132 are 1, 4/5, 3/5, 2/5, 1/5, respectively. It should be noted that the target opening is a ratio of a cross-sectional area of the opening of the air outlet to a cross-sectional area of the opening.
And S220, after the vehicle is adjusted to the current gear from the previous gear for the first set time, adjusting the opening of the air outlet to be the target opening.
For example, the first set time period is 5s to 10s, and after the controller detects that the gear of the vehicle is changed and the first set time period is, for example, 8s, the controller respectively controls the first motor 212 and the second motor 222 to rotate by a certain number of revolutions, so that the first air flap 211 and the second air flap 221 respectively rotate by corresponding angles around respective rotating shafts, and the opening degrees of the first air outlet 131 and the second air outlet 132 reach the target opening degrees.
Obtaining the target opening degree of the first air outlet 131 and the target opening degree of the second air outlet 132 according to the step S210, adjusting the opening degree of the first air outlet 131 and the opening degree of the second air outlet 132 to the target opening degrees, and reducing the influence of the air flow on the air flow of the first air outlet 131 and the second air outlet 132, thereby ensuring that the air flow of the first air outlet 131 and the second air outlet 132 is matched with the heat exchange amount of the outdoor heat exchanger, ensuring that the compressor is regularly started and stopped, and keeping the pipeline pressure in the refrigerant loop relatively stable, thereby prolonging the service life of the compressor and the refrigerant circulation pipeline.
When the vehicle is adjusted from the previous gear to the current gear for the first set time, the opening degree of the air outlet is adjusted to be the target opening degree, so that the opening degree of the air outlet is adjusted to be the target opening degree after the speed of the vehicle reaches the new stable speed after gear shifting, and the influence of unstable vehicle speed on the air output of the air outlet is further reduced.
It will be appreciated by those skilled in the art that the first set time period of 8s is only one specific embodiment and may be adjusted by those skilled in the art, for example, the first time period may be 5s, 6s, 9s, 10s, etc. In addition, the opening degree of the air outlet is adjusted to the target opening degree after the vehicle is adjusted from the previous gear to the current gear for the first set time period, which is only a preferable embodiment, and a person skilled in the art can adjust the opening degree to the target opening degree as required, for example, immediately adjust the opening degree of the air outlet to the target opening degree when the vehicle is adjusted from the previous gear to the current gear. In addition, n is 5 only one specific embodiment, and those skilled in the art can make adjustments according to actual situations to adapt to specific applications, for example, the number of forward gears of a part of vehicles is 4, 6, 7, etc., and n is set to be 4, 6 or 7 correspondingly.
It can be further understood by those skilled in the art that the first air outlet 131 and the second air outlet 132 are only disposed on the top plate 11, and those skilled in the art can adjust the arrangement according to the requirement, for example, only one air outlet may be disposed on the top plate 11, or three, four or more air outlets may be disposed on the top plate 11. In addition, the opening adjusting device can also be arranged in a way that the linear motor drives the air plate to adjust the opening of the air outlet in a translation way.
Further, the speed of the vehicle in the process of backing the vehicle is basically the same as the speed of the vehicle in the 1-gear state, the speeds are lower, the influence of airflow generated by the running of the vehicle on the airflow of the air outlet of the vehicle-mounted overhead air conditioner is smaller, and the air outlet can be fully opened at the moment. That is, when the shift position of the vehicle is currently the reverse gear, the target opening degree of the air outlet is set to 1. It can be understood by those skilled in the art that calculating the target opening of the air outlet according to the formula K ═ n +1-i)/n is only a specific setting, and those skilled in the art can make adjustments as long as the target opening is negatively correlated to the overall gear of the vehicle, for example, the forward gear of the vehicle includes 1 gear, 2 gear, 3 gear, 4 gear and 5 gear, when the vehicle is currently in 1 gear or 2 gear, the target opening of the air outlet is 4/5, and when the vehicle is currently in 3 gear, 4 gear or 5 gear, the target opening of the air outlet is 2/5.
In another possible embodiment, after the controller detects that the gear of the vehicle is changed, the opening degree of the air outlet is gradually adjusted to the target opening degree within the second set time period. After the vehicle is shifted, a certain time is needed for the speed of the vehicle to reach the latest stable speed, and the opening degree of the air outlet is gradually adjusted to the target opening degree in the process, namely the opening degree of the air outlet is gradually changed to the target opening degree in the process, so that the opening degree of the air outlet is gradually changed along with the change of the speed of the vehicle in the process of changing the speed of the vehicle, and the influence of the changed air flow generated in the running process of the vehicle on the air flow of the air outlet can be further reduced.
With continued reference to fig. 4, the control method of the in-vehicle rooftop air conditioner further includes the steps of:
step S310, calculating an increase amount of the rotation speed of the blower of the air inlet according to a formula N ═ i × Δ N/N according to the current gear of the vehicle, where N is the increase amount of the rotation speed of the blower of the air inlet, i is the current forward gear of the vehicle, and Δ N is a preset rotation speed increase amount. For example, Δ N may be 10 rpm, 12 rpm, 15 rpm, or the like.
And step S320, increasing the rotating speed of the fan of the air inlet by the increasing amount.
When the current gear of the vehicle is reverse gear, the increment of the rotating speed of the fan of the air inlet is set to be delta N/N.
For some on-board overhead air conditioners, both the air inlet and the air outlet are provided in the roof panel 11. Because a negative pressure area is formed above the top plate 11 in the running process of the vehicle, the generated negative pressure can block the air inlet of the air inlet, the higher the running speed of the vehicle is, the higher the relative movement speed of the vehicle-mounted overhead air conditioner and air is, and the larger the air flow generated by the relative movement can block the air inlet flow of the air inlet. In the running process of the vehicle, the increase of the rotating speed of the fan of the air inlet is calculated according to the current gear of the vehicle and the formula N ═ i Δ N/N, the rotating speed of the fan of the air inlet is increased by the increase, the air inlet quantity of the air inlet can be increased, the gas flow of the air inlet is ensured to be matched with the heat exchange quantity of the outdoor heat exchanger, the compressor is ensured to be started and stopped regularly, the pipeline pressure in the refrigerant loop is kept relatively stable, and therefore the service life of the compressor and the refrigerant circulating pipeline is prolonged.
In another aspect, the present invention further provides a vehicle-mounted ceiling type air conditioner, including: the air conditioner control system comprises a memory, a processor and a computer program, wherein the computer program is stored in the memory and is configured to be executed by the processor to realize the control method of the vehicle-mounted overhead type air conditioner of any one of the embodiments.
