Naturally, the solar cell system may be powered by a set value and store more generated power than the set value, and the whole vehicle power supply may supply the rest of the electric energy.

Here, when the generated power does not satisfy the target power consumption, the priority control compressor is based on the above formula: w (W) Consumption of =a * N+b, the compressor is operated at an actual target rotation speed matched with the generated power, but W is the same as that Consumption of The generated power, a and b are known parameters, and the actual target rotating speed is N. When the temperature in the vehicle does not meet the comfort setting, the energy storage system and the solar battery system are controlled to jointly supply power to the compressor; or the energy storage system is controlled to replace the solar battery system to independently supply power to the compressor so that the compressor can operate at a target rotating speed to meet the refrigeration requirement.
According to the method, the solar power generation power and the target power consumption of the compressor are accurately calculated and matched, when the power generation power meets the starting condition of the air conditioning system, namely, the power generation power meets the target power consumption, the power generation power is particularly preferably higher than s times of the lowest starting power consumption of the compressor (s is a safety coefficient, the value range is 1.1-2), the solar battery system is used for supplying power to the compressor, direct utilization of the power generation power can be achieved, the link of buffering and converting through the storage battery is reduced, and the utilization efficiency of solar energy can be effectively improved.
On the basis of general automatic control of the electric air conditioner, the invention supplies power through the solar panel, and realizes the parking of long-distance trucks and the refrigeration requirement of driving air conditioners. The long-distance truck with traditional power generally has a special parking air conditioner (an engine mechanically driven air conditioner compressor) besides a driving air conditioner (a loading battery electrically driven air conditioner compressor), and when the power generated by the solar battery meets the minimum starting power consumption requirement of the parking air conditioner, the parking air conditioner is driven to cool by using the power supply of the solar battery system no matter in a parking or driving state at the moment, and only needs refrigeration. If the vehicle is a long-distance truck driven by new energy, the common cab only has one set of electric air conditioning system, and when the power generated by the solar battery meets the minimum starting power consumption requirement of the electric air conditioner, the power supply of the electric air conditioner is switched from the whole vehicle power battery to the solar battery system.
Further, the method further comprises the steps of:
s50: acquiring outdoor environment temperature;
s60: obtaining the temperature in the vehicle;
here, the two steps of acquiring the outdoor ambient temperature and acquiring the temperature in the vehicle may be synchronized or unsynchronized, and there is no strict sequence, which is not strictly limited herein, and the existence of the two steps in the subsequent steps also does not limit the sequence, and meanwhile, the front-to-back relationship between the different steps involved in the present invention is not limited to the sequence written in the present application, unless the sequence is explicitly specified, and the steps need to be strictly in the specified sequence. It should be noted that, considering that the air conditioning system is in a fluctuating state just after starting operation, the engagement between step S42 and steps S50 and S60 is preferably performed at a certain interval. Of course, the steps S42 and S50 and S60 may be performed simultaneously regardless of the operation state of the air conditioning system or the stable operation of the air conditioner.
S70: acquiring the in-vehicle thermal load based on the in-vehicle thermal load and a model of the first solar radiation intensity, the outdoor ambient temperature and the in-vehicle temperature;
the above-mentioned in-vehicle heat load meets with the first solar radiation intensity, the outdoor ambient temperature, the in-vehicle temperature model:
Q heat of the body =d * (T+ c * I+t-23) +e; wherein, the liquid crystal display device comprises a liquid crystal display device,

S80: acquiring the air quantity of a blower;
s90: acquiring the air conditioner refrigerating capacity based on a model of the air conditioner refrigerating capacity, the actual target rotating speed and the air quantity of the blower;
the model of the air conditioner refrigerating capacity, the actual target rotating speed and the blower air quantity meets the following conditions:
Q cold water =(L 1* q ve 3 +L 2* q ve 2 +L 3* q ve +L 4 ) * N 2 +(L 5* q ve 3 +L 6* q ve 2 +L 7* q ve
+L 8 ) * N+(L 9* q ve 3 +L 10* q ve 2 +L 11* q ve +L 12 )；
In which Q Cold water The unit is w for the refrigerating capacity of the air conditioner; q ve The current air quantity of the blower is expressed as m 3 /h; n is the actual target rotation speed, and the unit is rpm; l (L) 1 、L 2 、L 3 、...、L 11 、L 12 Is a parameter.
In the above model, Q Cold water The level of the N-order polynomial of N can be set according to the need, and in this embodiment, a second-order polynomial of N is used. Where the units of the parameters are matched according to the equation.
Here, in order to meet the requirements of comfort in the vehicle, Q may be obtained by Cold water =Q Heat of the body The relation between the solar radiation intensity and the outdoor environment temperature, the rotation speed of the compressor and the air quantity of the blower can be obtained.
S100: judging whether the refrigerating capacity of the air conditioner is smaller than the internal heating load of the vehicle or not;
s101: when the air conditioner refrigerating capacity is smaller than the in-car thermal load, executing the steps of:
s102: adjusting the air quantity of the blower until the air conditioning refrigerating capacity is matched with the current internal heating load of the vehicle; wherein, the power supply of the blower is the whole vehicle power supply.
Because the low-voltage power of the blower is provided by the whole vehicle level, in order to enable the equation to be satisfied, when the rotating speed of the compressor is limited by the fact that the generated power cannot be improved enough, namely, the refrigerating capacity of the air conditioner is smaller than the internal heat load of the vehicle, the air quantity of the blower is increased, and more power can be provided by the whole vehicle power supply, so that the comfort requirement of a truck cab is met. Of course, when the air conditioner refrigerating capacity is larger than the load in the vehicle, the air quantity of the air blower can be reduced or the target rotating speed can be reduced, so that the comfort is ensured and the energy is saved.
The air quantity of the air blower can be effectively controlled through accurate calculation of the internal heat load of the vehicle and the refrigerating capacity of the air conditioner, so that the comfort requirement in the vehicle is ensured, the application of coupling of solar power generation power and the refrigerating function of the air conditioner in the solar automobile air conditioning system is effectively solved, and the cooperation of the solar energy system, the air conditioning refrigerating system and the whole vehicle power supply is improved.
Still further, the method further comprises the steps of:
acquiring the actual time when the refrigerating capacity of the air conditioner is continuously smaller than the internal heat load of the vehicle;
judging whether the actual time is not less than a first preset time or not;
the first preset time can be based on the relation between the air-conditioning cooling capacity and the thermal load in the vehicle
When the actual time is not less than the first preset time, executing the steps of:
judging whether the temperature in the vehicle is higher than the set comfort temperature or not;
in particular, the comfort temperature set here may be determined according to the user's experience, such as 25 ℃, 26 ℃, 27 ℃, etc.
When the temperature in the vehicle is higher than the set comfort temperature, executing the steps of:
popup dialog;
based on the dialog box, acquiring an input instruction;
when the input instruction is a first instruction, controlling a whole vehicle power supply to replace the solar battery system to supply power to the compressor singly or controlling the whole vehicle power supply and the solar battery system to replace the actual target rotating speed, and controlling the compressor to operate at the target rotating speed;
when the input instruction is a second instruction, the solar battery system is controlled to continuously and independently supply power to the compressor, the compressor is controlled to continuously operate at the actual target rotating speed until the temperature in the vehicle is higher than a first temperature threshold value, the whole vehicle power supply is controlled to replace the solar battery system to independently supply power to the compressor, and the compressor is controlled to operate at the target rotating speed instead of the actual target rotating speed.
Here, the first instruction is characterized by selecting a priority to ensure comfort and the second instruction is characterized by selecting a power saving mode. The content displayed in the talking frame may correspond to the first instruction and the second instruction, and the present invention is not limited to the content and form displayed therein.
Through the pop-up dialog box, drivers and passengers can choose whether to preferentially ensure the temperature comfort in the vehicle according to personal requirements, switch the air conditioning system power supply into the whole vehicle power supply or choose to enter the power saving mode. Here, the first temperature threshold may be set to 28 ℃, or the corresponding highest sustainable temperature may be set according to the available power margin of the solar cell system.
Specifically, in the actual application process, based on the dialog box, when the input instruction is not acquired within the second preset time, executing the steps:
and controlling the whole vehicle power supply to replace the solar battery system to supply power to the compressor singly or controlling the whole vehicle power supply and the solar battery system to replace the actual target rotating speed by the target rotating speed, and controlling the compressor to operate.
It is noted that the acquisition of the duration of the air conditioning cooling capacity being continuously smaller than the in-vehicle heat load preferably occurs when the air conditioning cooling capacity is continuously smaller than the in-vehicle heat load after the blower air volume is adjusted to the maximum air volume value. Then, at this time, the step of adjusting the air quantity of the blower to match the air conditioning refrigerating capacity with the current internal heat load of the vehicle specifically includes the steps of:
Judging whether the air quantity of the blower reaches a maximum air quantity value or not;
when the air quantity of the blower reaches a value which is not the maximum air quantity, executing the steps of:
increasing the air quantity of the blower until the refrigerating capacity of the air conditioner is not less than the current internal heating load of the vehicle;
when the air quantity of the blower reaches the maximum air quantity value, executing the steps of:
a timer is started to obtain the actual time.
