If the opening degree of each wind sweeping blade is A after adjustment1＝45°、A2＝50°、A3＝35.5°、A4＝45°、A5＝40.5°、A6＝48°、A7＝41°、A8When 47 °, the sum of the current opening degrees az352 ° for 45 ° +50 ° +35.5 ° +45 ° +40.5 ° +48 ° +41 ° +47 °. If the sum of the opening degrees A before the adjustment (i.e. the previous period) is equal toz-1When the angle is 360 degrees, the sum of the current opening degrees is in proportion Ar＝352°/360°＝97.8％。
Specifically, the zone control process of the new energy automobile air conditioner control system includes: the space in the vehicle is divided into a plurality of different areas (such as the front part of the vehicle, the middle part of the vehicle and the back part of the vehicle) along the direction of the vehicle body according to requirements, and each area comprises an independent evaporation fan set, a plurality of wind sweeping blades, corresponding position sensors and corresponding driving motors.

Fig. 5 is a schematic flow chart of an embodiment of a control method for realizing speed regulation of a fan by calculating the opening degree of a sweeping blade. As shown in fig. 5, the control process for realizing the speed regulation of the fan by calculating the opening of the sweeping blade includes:
step 1, through the new energy automobile air conditioner control system, the wind sweeping blades are divided into regions according to the same dividing conditions, and the wind sweeping blades in each region are controlled in a unified mode. The wind sweeping blade is an adjustable wind sweeping blade, the rotation angle of the wind sweeping blade can be accurately controlled through the rotation of the driving motor control shaft, the angle of the wind sweeping blade can also be manually adjusted, and the angle adjusting range is 0-90 degrees.
Step 2, Ar＝Az/Az-1Wherein A iszIs the sum of the current opening of the blades, Az-1Is the sum of the opening degrees of the last period of the wind sweeping blades, Az(or A)z-1)＝A1+A2+A3+...+AnWherein A isnFor the opening of each of the sweeping blades.
And 3, when the air conditioner is started, driving the wind sweeping blades in the area to have default opening degrees (45 degrees) by the driving motor, and setting the current total opening degree ratio ArIs 100%. According to the current TInner ringAnd TSetting upAnd setting the initial rotating speed of the evaporation fan set in the region according to the difference value delta T.
Wherein, according to the current TInner ringAnd TSetting upThe difference value delta T, the initial rotating speed of the evaporation fan set in the set area comprises: setting the initial rotation speed, each air conditioner manufacturer has own control logic.
For example: the rotating speed of the evaporation fan set is set to be 7 gears of rotating speed, and the rotating speed corresponds to 1-7 gears of wind gears respectively. And entering a judging step by calculating the obtained delta T. The determination conditions are respectively as follows: delta T is less than-1 ℃, delta T is more than or equal to 1 ℃ and less than 3 ℃, delta T is more than or equal to 3 ℃ and less than 5 ℃, delta T is more than or equal to 5 ℃ and less than 7 ℃, delta T is more than or equal to 7 ℃ and less than or equal to 9 ℃, and delta T is more than or equal to 9 ℃, and the corresponding operation wind shield is 1-7 grades. Taking a certain fan of my department as an example, the fan rotating speeds corresponding to 1-7 wind gears from low to high respectively are as follows: 2200rpm, 2400rpm, 2600rpm, 2800rpm, 3000rpm, 3200rpm, 3400 rpm.
Step 4, position sensing on the shaft due to the fact that passengers can manually adjust the opening degree of the wind sweeping bladesThe device will detect the real-time wind sweeping blade opening degree AnWhen the opening A is monitorednAnd feeding back data to the controller when there is a change. When the change is stable for 10s, the total sum A of the current opening degree is calculatedzAnd the current opening sum ratio ArThe formula is Az＝A1+A2+A3+...+An。
For example: the total 8 air outlets (can adjust the blade of sweeping the wind) in this region, the passenger's perception condition increase or reduce the aperture of the blade of sweeping the wind through oneself. If the opening degree of each wind sweeping blade is A after adjustment1＝45°、A2＝50°、A3＝35.5°、A4＝45°、A5＝40.5°、A6＝48°、A7＝41°、A8When 47 °, the sum of the current opening degrees az352 ° for 45 ° +50 ° +35.5 ° +45 ° +40.5 ° +48 ° +41 ° +47 °. If the sum of the opening degrees A before the adjustment (i.e. the previous period) is equal toz-1When the angle is 360 degrees, the sum of the current opening degrees is in proportion Ar＝352°/360°＝97.8％。
Step 5, if ArThe rotating speed of the fan in the area needs to be increased if the rotating speed is more than 100 percent; if ArBelow 100% it is believed that the fan speed in this region needs to be reduced. The controller will pass ArAnd adjusting the rotating speed of the evaporation fan in the same proportion. For example, Ar120% of the total mass of the evaporator, and the rotation speed N of the evaporation fan0When the rotation speed is 2000rpm, the target rotation speed of the evaporation fan is adjusted to be 2000 × 120%.
Step 6, after the rotating speed of the evaporation fan is adjusted, the driving motor restores the driving wind sweeping blades to the default opening degree (45 degrees), and the current opening degree sum ratio A is resetrTo 100%, and then a new round of control is entered.
For example: taking a tourist bus as an example, the air duct interior trimming panels above the heads of passengers and drivers are provided with 54 adjustable air sweeping blades in total, and 3 areas are divided along the direction of the bus body and are respectively arranged in front of the bus, in the middle of the bus and behind the bus. Wherein the number of the adjustable air sweeping blades in each area is respectively 20 in front of the vehicle, 16 in the vehicle and 18 behind the vehicle, and each area is respectively provided with an independent evaporation fan set, a temperature sensor and position sensors with the same number as the air sweeping bladesAnd a drive motor. Correspondingly, 3 fan driving modules, 3 temperature regulating modules, 54 position detection modules and 54 motor driving modules are required to be arranged in the air conditioner controller, so that the purpose of independently controlling the temperature in the areas by 3 areas is achieved. Taking the air conditioner and the area behind the vehicle as an example, when the air conditioner is started for the first time, the controller sends out a control signal for driving the motor, the opening degree of the wind sweeping blade is controlled to be the default opening degree (45 degrees), and the sum of the current opening degrees is AzSet 45 ° -18 ° -810 °, and set the current opening sum arThe proportion is 100 percent. By means of a function of the current TInner ringAnd TSetting upIs equal to (e.g. T)Inner ring＝28℃，TSetting upAnd (26 ℃), and setting the initial rotating speed (2600 rpm for example) of the evaporator fan set in the region. If the rear seat passenger feels cold, the opening A of the wind sweeping blade is manually reducednAnd when the change is detected to be stable for 10s, the passenger is considered to be adjusted. Calculating the total sum A of the current opening degreez(e.g., 688.5 deg.), and the ratio A of the current opening sumr688.5 °/810 ° -85%. Judging the sum of the current opening degree to be Ar(85%) is less than 100%, it is determined that the fan speed needs to be reduced, and the ratio A of the fan speed regulation ratio and the sum of the current opening degreerThe same is true, i.e. the adjusted wind speed is 2600 × 85% — 2210 rpm. After the rotating speed of the fan is adjusted, the driving motor drives the wind sweeping blade to recover to the default opening degree (45 degrees), and the current opening degree sum total ratio A is resetrAnd the control flow is 100 percent, and a new round of control process is entered.
