In addition, it should be noted that, in the description of the present invention, unless otherwise specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated Connection; it can be a direct connection, an indirect connection through an intermediary, or an internal connection between two elements. Those skilled in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

Referring to Fig. 1, the control method of the parking air conditioner of the present invention will be introduced. Wherein, FIG. 1 is a main step diagram of the control method of the parking air conditioner of the present invention.

Based on the problem mentioned in the background that the existing parking air conditioner cannot reduce the manufacturing cost and the use cost on the basis of satisfying rapid cooling after starting up, the present invention provides a method for controlling the parking air conditioner, and the parking air conditioner is applied to vehicles. As shown in Figure 1, the control method of the parking air conditioner includes:

Step S1, acquiring the temperature inside the vehicle and the temperature outside the vehicle in real time.

The interior and exterior parts of the parking air conditioner are respectively provided with an interior temperature sensor and an exterior temperature sensor, and the interior temperature sensor and the exterior temperature sensor are connected with the controller of the parking air conditioner. After the parking air conditioner is turned on, the interior temperature sensor and the exterior temperature sensor respectively detect the interior temperature and exterior temperature in real time and send the interior temperature and exterior temperature to the controller.

Step S2 , judging whether the temperature inside the vehicle - the temperature outside the vehicle is greater than the first preset value, if yes, execute step S3 , if not, execute step S4 .

Step S3, replacing the air inside and outside the car, and controlling the parking air conditioner to operate in an overclocking mode.

It should be noted that replacing the air inside and outside the car and controlling the overclocking mode of the parking air conditioner can be performed simultaneously or sequentially. Controlling the overfrequency mode of the air conditioner operation refers to overclocking the compressor of the parking air conditioner, the fan inside the car and the fan outside the car, that is, the compressor, the fan inside the car and the fan outside the car all run at a frequency exceeding the rated frequency.

Step S4, controlling the parking air conditioner to operate in a normal mode.

Through such a control method, when the temperature inside the vehicle is greater than the temperature outside the vehicle and the difference between the temperature inside the vehicle and the temperature outside the vehicle is greater than the first preset value, the temperature inside the vehicle can be quickly lowered, and the parking air conditioner can be reduced. The manufacturing cost and the user's use cost are reduced, and the user's use experience is optimized.

Referring to Fig. 2, the method for controlling the parking air conditioner according to the first embodiment of the present invention will be introduced. Wherein, FIG. 2 is a flow chart of the method for controlling the parking air conditioner according to the first embodiment of the present invention.

In the first embodiment, as shown in FIG. 2, the control method of the parking air conditioner of the present invention includes:

Step S110, acquiring the temperature inside the vehicle and the temperature outside the vehicle in real time.

After the parking air conditioner is turned on, the temperature inside the vehicle and the temperature outside the vehicle are respectively detected in real time by means of the temperature sensor inside the vehicle and the temperature sensor outside the vehicle.

Step S120, judging whether the "inside temperature - outside temperature" is greater than the first preset value (eg 5°C), if yes, execute step S131, if not, execute step S142 and step S143. Wherein, the first preset value is a positive number.

Step S131, reminding the user to open the window.

For example, the voice announcement device on the parking air conditioner sends out relevant information such as "please open the window" to prompt the user to open the window.

Step S132 , controlling the fan inside the vehicle and the fan outside the vehicle to operate at overfrequency.

Specifically, control the fan inside the car and the fan outside the car to run at a speed exceeding the rated speed.

Step S133, controlling the overfrequency operation of the compressor of the parking air conditioner.

That is to say, after the parking air conditioner is turned on, the inside temperature sensor and the outside temperature sensor are used to detect the inside temperature and the outside temperature in real time. If the inside temperature is greater than the outside temperature and the difference between the inside temperature and the outside temperature If the temperature is greater than the first preset temperature, the user will be reminded to open the window, and the fan inside the car, the fan outside the car and the compressor will be overclocked. The outdoor fan and compressor are running normally. After "reminding the user to open the window, control the overclocking operation of the indoor fan, the outdoor fan and the compressor", determine whether the temperature inside the car has dropped to a point where the difference between the temperature inside the car and the temperature outside the car is less than or equal to the second preset value, when the temperature inside the car When the difference between the temperature and the outside temperature is equal to the second preset value, the user is reminded to turn off the car, and the fan inside the car, the fan outside the car and the compressor are controlled to operate normally, that is, the parking air conditioner is controlled to operate in the normal mode.

When the window is open, the fan in the car rotates to form an air flow between the inside and outside of the car. The air with a higher temperature inside the car flows out from the window, and the air with a lower temperature outside the car flows in from the window. In the car, at the same time, the fan in the car, the fan and the compressor are in overclocking operation, that is, the parking air conditioner is in an overfrequency operation state. Cool down. The heat in the car is directly discharged to the outside of the car through the exchange of air inside and outside the car, which reduces the cooling capacity required to lower the temperature inside the car to the target temperature, not only shortens the cooling time inside the car, but also saves energy.

Preferably, the vehicle windows include vehicle windows on the left and right sides and a sunroof on the vehicle roof. The air inlet of the fan in the car is close to the sunroof, and the outlet of the fan in the car is far away from the sunroof. The sunroof, the space in the car, and the windows on the left and right sides form the air exchange flow between the inside and outside of the car, and the air exchange is smoother.

It should be noted that the first preset value of 5°C is only a specific setting method, which can be adjusted in practical applications. For example, the first preset value can be 3°C, 4°C, 6°C or other Suitable positive temperature values, etc. The second preset value of 0°C is also a specific setting method, which can be adjusted in practical applications, such as the second preset value can be -1°C, 1°C, 2°C or other suitable temperature values, etc. .

Referring to FIG. 3 , the method for controlling the parking air conditioner according to the second embodiment of the present invention will be introduced. Wherein, FIG. 3 is a flow chart of the control method of the parking air conditioner according to the second embodiment of the present invention.

In the second embodiment, the window of the vehicle is equipped with a window opening and closing device that drives the window to open and close, and the window opening and closing device is connected to the controller of the parking air conditioner. As shown in Figure 3, the control method of the parking air conditioner of the present invention comprises:

Step S210, acquiring the temperature inside the vehicle and the temperature outside the vehicle in real time.

Step S220, judging whether "inside temperature - outside temperature" is greater than a first preset value (eg 5°C), if yes, execute step S231, if not, execute step S242 and step S243. Wherein, the first preset value is a positive number.

Step S231, controlling the window opening and closing device to open the window.

Step S232 , controlling the fan inside the vehicle and the fan outside the vehicle to operate at overfrequency.

Step S233, controlling the overfrequency operation of the compressor of the parking air conditioner.

It should be noted that step S232 is executed simultaneously with step S232. In addition, step S232 and step S232 may be performed after step S231, or may be performed simultaneously with step S231.

Step S234, judge whether "inside temperature - outside temperature" is less than or equal to the second preset value (such as 0°C), if yes, execute step S241, otherwise return to step S232 and step S233. Wherein, the second preset value is less than or equal to the first preset value.

Step S241, controlling the window opening and closing device to close the window.

Step S242, controlling the normal operation of the indoor fan and the outdoor fan.

Step S243, controlling the normal operation of the compressor of the parking air conditioner.

That is to say, the difference between the second embodiment and the first embodiment is that the operation of reminding the user to open and close the car window is replaced by the controller of the parking air conditioner to control the car window opening and closing device to open and close the car window. window way. With such a setting, the user does not need to open and close the vehicle window, which provides more convenience to the user. In addition, it can also avoid the situation that the user forgets to open or close the window when the user is reminded to open or close the window, which affects the cooling rate in the car, and further optimizes the user experience.

Referring to Fig. 4, the method for controlling the parking air conditioner according to the third embodiment of the present invention will be introduced. Wherein, FIG. 4 is a flow chart of the control method of the parking air conditioner according to the third embodiment of the present invention.

In a third embodiment of the present invention, the parking air conditioner is equipped with a fresh air system. The fresh air system includes an air inlet duct and an air outlet duct. One end of the air inlet duct communicates with the outside of the car, the other end of the air inlet duct communicates with the fan inside the car of the parking air conditioner, and one end of the air outlet duct communicates with the interior of the car. The other end is connected with the outside of the car, and an exhaust fan is arranged in the air outlet duct. Driven by the fan in the car, the air outside the car can enter the air intake duct and be blown into the car from the air outlet of the fan in the car. Driven by the exhaust fan, the air in the car is discharged from the air outlet duct to the outside of the car.

As shown in Figure 4, the control method of the parking air conditioner of the present invention comprises:

Step S310, acquiring the temperature inside the vehicle and the temperature outside the vehicle in real time.

Step S320, judging whether the "inside temperature - outside temperature" is greater than the first preset value (eg 5°C), if yes, execute step S331, if not, execute step S342 and step S343. Wherein, the first preset value is a positive number.

Step S331, controlling the fresh air system to start.

That is to say, the main difference between the third embodiment and the first embodiment and the second embodiment is that the replacement of the air inside the car with the air outside the car is no longer achieved by opening the window and rotating the fan inside the car. Instead, the fresh air system is used to replace the air inside the car with the air outside the car. Since many air conditioners are equipped with a fresh air system, the fresh air system is usually used to adjust the freshness of the air in the car. In the third embodiment of the present invention, the fresh air system configured by the parking air conditioner is used to replace the air at a higher temperature inside the car with the air at a lower temperature outside the car, without improving the structure of the parking air conditioner to avoid The increase in manufacturing costs, and compared with opening the windows and turning on the fan inside the car, the efficiency of replacing the air inside the car with the air outside the car through the fresh air system is higher.

It should also be noted that the fresh air system includes an air inlet duct and an air outlet duct. One end of the air inlet duct communicates with the outside of the vehicle, and the other end of the air intake duct communicates with the inside fan of the parking air conditioner. One end of the duct is connected to the inside of the car, and the other end is connected to the outside of the car. An exhaust fan is installed in the air outlet duct. This setting method is only a specific setting method. In practical applications, it can also be other forms of fresh air For example, in another feasible setting method, the fresh air system includes an air inlet duct and an air outlet duct, one end of the air inlet duct communicates with the outside of the car, and the other end of the air inlet duct communicates with the interior of the parking air conditioner. The fresh air outlet on the casing is connected, and an air inlet fan is arranged in the air inlet duct. One end of the air outlet duct is connected with the exhaust inlet on the inner casing of the parking air conditioner, and the other end is connected with the outside of the car. There is an exhaust fan in the tunnel.

In another feasible implementation manner, the fresh air system includes an air intake duct, one end of the air intake duct communicates with the outside of the vehicle, and the other end of the air intake duct communicates with the interior fan of the parking air conditioner. When the fresh air system is working, the air outside the car enters the car through the air intake duct, the air pressure inside the car increases, and the air inside the car is discharged from the gap in the car compartment. When the parking air conditioner control method of the present invention is executed, during the process of controlling the activation of the fresh air system to replace the air inside and outside the car, the windows of the car can be opened at the same time to promote the replacement of air inside and outside the car.
