Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention provides a solution, which is characterized in that the temperature of a radiator of a vehicle driving system is obtained, and the internal circulation and external circulation air volume control is carried out on a vehicle air conditioner according to the temperature of the radiator, so that the excessive change of the heat dissipation capacity of a condenser of the vehicle air conditioner is avoided, the influence on the heat dissipation of the radiator of the driving system is reduced, and the problem of the overhigh temperature of the driving system caused by the change of the internal circulation and the external circulation of the vehicle air conditioner is solved.
Referring to fig. 1, in an embodiment, a control method of an air conditioner for a vehicle includes the steps of:
step S10, obtaining the radiator temperature of the vehicle driving system;
in this embodiment, the vehicle includes a drive system and an on-vehicle air conditioner, and a radiator of the drive system is disposed behind a condenser of the on-vehicle air conditioner. The rear direction refers to the rear direction from the vehicle head to the vehicle tail, and when the vehicle normally runs, the airflow passing through the vehicle-mounted air conditioning condenser passes through the radiator of the driving system.
Alternatively, as shown in fig. 2, a temperature sensor S4 is provided on the radiator of the vehicle drive system for collecting the radiator temperature.
Alternatively, the radiator of the vehicle driving system is generally a water-cooled radiator, and in this case, the temperature sensor may be disposed at an outlet of the water-cooled radiator, and the temperature detected by the temperature sensor is the water temperature at the outlet of the water-cooled radiator.
Optionally, the vehicle is a hybrid vehicle or a pure electric vehicle. When the vehicle is a pure electric vehicle, the heat dissipation capacity of a driving motor of the driving system is smaller, and at the moment, the influence of the change of the heat dissipation capacity of the condenser on the heat dissipation of the driving motor is larger.
Optionally, after the radiator temperature is obtained, it may be further detected whether the radiator temperature is greater than a preset threshold, and if so, it indicates that the heat load of the vehicle driving system is high, so step S20 may be executed to reduce the influence of the vehicle air conditioner on the heat dissipation of the radiator of the vehicle driving system, so as to reduce the heat load of the vehicle driving system and avoid the temperature of the vehicle driving system being too high.
And step S20, adjusting the opening of an air door of the vehicle air conditioner according to the temperature of the radiator so as to adjust the internal circulation air volume and the external circulation air volume of the vehicle air conditioner.
In this embodiment, as shown in fig. 2, the vehicle air conditioner is provided with an internal circulation air duct system S2 and an external circulation air duct system S2, and the internal circulation air duct system S2 includes an internal circulation air duct, an external circulation air duct system and a damper, and the sizes of the openings of the internal circulation air duct and the external circulation air duct system can be adjusted by adjusting the opening degree of the damper, so as to change the internal circulation air volume and the external circulation air volume. It can be understood that, due to the inconsistency between the inside temperature and the outside ambient temperature, the heat load of the vehicle air conditioner is different after the inside circulation air volume and the outside circulation air volume are changed, and therefore the heat dissipation capacity of the condenser of the vehicle air conditioner is changed.
Alternatively, as shown in fig. 3, when the damper is closed, the damper is in position 2, the opening degree of the damper is zero, the vehicle air conditioner is in the internal circulation mode, and the external circulation air volume is equal to the minimum external circulation air volume. When the opening degree of the air door reaches the maximum opening degree, the air door is located at the position 1, the vehicle air conditioner is in an external circulation mode, and the internal circulation air volume is equal to the minimum internal circulation air volume. The minimum external circulation air volume may be zero, and the minimum internal circulation air volume may also be zero.
Alternatively, as shown in fig. 3, the damper is a rotatable mechanism, the damper can be driven by a motor to rotate, and the opening degree of the damper is adjusted by rotating the damper between the position 1 and the position 2, so that the vehicle air conditioner can be switched between the inner circulation mode and the outer circulation mode.
Optionally, a corresponding angle value is determined according to the temperature of the radiator, and the air door is controlled to rotate to the angle value, so that the opening degree of the air door is adjusted.
Alternatively, when the opening degree of the air door of the vehicle air conditioner is adjusted according to the temperature of the radiator, if the temperature of the radiator is too high, the heat radiation amount of the vehicle air conditioner condenser can be reduced by adjusting the internal circulation air amount and the external circulation air amount, so that the influence of the vehicle air conditioner condenser on the temperature of the radiator is reduced, and the temperature of the radiator is reduced. If the temperature of the radiator is not too high, the opening degree of the air door can be controlled according to the original control logic of the vehicle-mounted air conditioner.
In the technical scheme disclosed in the embodiment, by acquiring the temperature of the radiator of the vehicle driving system and controlling the internal circulation and external circulation air volume of the vehicle air conditioner according to the temperature of the radiator, the excessive change of the heat dissipation capacity of the condenser of the vehicle air conditioner is avoided, and the influence on the heat dissipation of the radiator of the driving system is reduced, so that the problem of the overhigh temperature of the driving system caused by the change of the internal circulation and the external circulation of the vehicle air conditioner is solved.
In another embodiment, as shown in fig. 4, on the basis of the embodiment shown in fig. 1, after step S10, the method further includes:
step S30, obtaining the refrigerant pressure of the condenser of the vehicle air conditioner;
in the present embodiment, as shown in fig. 2, the condenser of the vehicle air conditioner is provided with a pressure sensor S3 for detecting a refrigerant pressure of the condenser. Optionally, the pressure sensor is disposed at the condenser refrigerant outlet and configured to detect a pressure at the condenser refrigerant outlet.
Step S20 includes:
and step S21, adjusting the opening degree of a damper of the vehicle air conditioner according to the radiator temperature and the refrigerant pressure.
In this embodiment, the opening of the air door of the vehicle air conditioner is comprehensively adjusted according to the temperature of the radiator and the pressure of the refrigerant, so as to meet the heat exchange requirement of the vehicle air conditioner and the heat dissipation requirement of the radiator of the vehicle driving system. For example, in a high temperature environment in summer, the driver presses a button of an air conditioner external circulation mode to introduce fresh air. At this moment, can arouse the rise of radiator temperature and refrigerant pressure, through the regulation of air door aperture, can be in order to guarantee that the radiator temperature can not be too high, introduce a certain amount of outer new trend of car again, satisfied driver's demand.
Optionally, a corresponding relationship among the radiator temperature, the refrigerant pressure, and the opening degree is preset, wherein the corresponding relationship may be a variation curve, a formula, table data, and the like, and may be obtained through an earlier test. Specifically, according to the corresponding relation among the temperature of the radiator, the pressure of the refrigerant and the opening degree, the opening degree corresponding to the temperature of the radiator and the pressure of the refrigerant can be determined, the opening degree is used as a target opening degree, the opening degree of the air door is adjusted to the target opening degree, and the adjustment of the internal circulation air volume and the external circulation air volume of the vehicle air conditioner is achieved.
Alternatively, the target opening degree is inversely related to the radiator temperature, and the target opening degree is inversely related to the refrigerant pressure, that is, the higher the radiator temperature is, the smaller the target opening degree is, so that the specific gravity of the internal circulation of the vehicle air conditioner is increased, thereby reducing the thermal load of the vehicle air conditioner and reducing the influence on the heat radiation of the radiator. The higher the refrigerant pressure is, the smaller the target opening degree is, and thus the specific gravity of the internal circulation of the vehicle air conditioner is increased, thereby reducing the refrigerant pressure of the vehicle air conditioner and reducing the influence on the heat dissipation of the radiator.
Optionally, a first heat dissipation load corresponding to the vehicle driving system may be calculated according to a temperature difference between the temperature of the radiator and the outdoor temperature, a second heat dissipation load corresponding to the condenser may be calculated according to a pressure difference between the refrigerant pressure and a preset standard pressure value, and then the opening degree of the damper of the vehicle air conditioner may be adjusted according to the first heat dissipation load and the second heat dissipation load.
Optionally, a heat dissipation index of a radiator of the vehicle driving system is preset, the heat dissipation index is a heat value emitted when the temperature of the radiator drops by one degree, and the heat dissipation index can be obtained according to a previous test. And multiplying the temperature difference between the temperature of the radiator and the outdoor temperature by the heat dissipation index to obtain a first heat dissipation load corresponding to the vehicle driving system.
Optionally, a pressure reduction index of a condenser of the vehicle-mounted air conditioner is preset, the pressure reduction index is a heat value emitted when the pressure of a refrigerant of the condenser is reduced by one degree, and the pressure reduction index can be obtained according to an earlier test. And multiplying the pressure difference between the refrigerant pressure and the preset standard pressure value by a pressure reduction index to obtain a second heat dissipation load corresponding to the condenser. The preset standard pressure value is a refrigerant pressure value of the condenser after the vehicle-mounted air conditioner is shut down.
Alternatively, when the opening degree of the damper of the vehicle air conditioner is adjusted according to the first heat dissipation load and the second heat dissipation load, since the first heat dissipation load of the electric vehicle is generally smaller than the second heat dissipation load, a heat load difference between the second heat dissipation load and the first heat dissipation load may be obtained, and the opening degree of the damper of the vehicle air conditioner may be adjusted according to the magnitude of the heat load difference. For example, when the thermal load difference is large, the opening degree of the damper of the vehicle air conditioner is decreased to increase the specific gravity of the internal circulation of the vehicle air conditioner.
Alternatively, a correspondence relationship between the heat load difference and the target opening degree may be set in advance, the target opening degree corresponding to the heat load difference is determined according to the correspondence relationship, and the opening degree of the damper is adjusted to the target opening degree.
Optionally, when the opening degree of the damper of the vehicle air conditioner is adjusted according to the first heat dissipation load and the second heat dissipation load, the opening degree of the damper of the vehicle air conditioner may be reduced when a difference between the heat loads of the second heat dissipation load and the first heat dissipation load is greater than a preset difference, and the first heat dissipation load is greater. And when the first heat dissipation load is smaller, the opening degree of the air door of the vehicle air conditioner is not adjusted.
In the technical scheme disclosed in this embodiment, the opening degree of an air door of the vehicle air conditioner is comprehensively adjusted according to the temperature of the radiator and the pressure of a refrigerant, so that the heat exchange requirement of the vehicle air conditioner and the heat dissipation requirement of a radiator of a vehicle driving system are both considered.
In yet another embodiment, as shown in fig. 5, on the basis of the embodiment shown in any one of fig. 1 to 4, before the step S10, the method further includes:
step S40, obtaining the environment temperature outside the vehicle;
and step S50, when the environment temperature outside the vehicle meets the preset temperature condition, executing the step of obtaining the temperature of the radiator of the vehicle driving system.
In this embodiment, when the vehicle is running, the outside ambient temperature may also be acquired, it is determined whether the adjustment of the throttle opening can reduce the influence on the heat dissipation of the drive system radiator according to the outside ambient temperature, and it is determined whether the step of the radiator temperature of the vehicle drive system needs to be executed.
In the technical scheme disclosed in this embodiment, the ambient temperature outside the vehicle is acquired, and when the ambient temperature outside the vehicle meets the preset temperature condition, the step of acquiring the temperature of the radiator of the vehicle driving system is executed to solve the problem that the heat dissipation of the radiator of the driving system is affected by the heat dissipation of the condenser.
In yet another embodiment, based on the embodiment shown in fig. 5, the preset temperature conditions include:
the environment temperature outside the vehicle is greater than the preset environment temperature, and the difference value between the environment temperature outside the vehicle and the environment temperature inside the vehicle is greater than the preset difference value.
When the environment temperature outside the vehicle is higher than the preset environment temperature and the difference value between the environment temperature outside the vehicle and the environment temperature inside the vehicle is higher than the preset difference value, the temperature outside the vehicle is higher, the temperature inside the vehicle is lower, and at the moment, the heat dissipation capacity of the condenser is changed too much due to the change of the internal circulation and the external circulation of the vehicle air conditioner, so that the heat dissipation of the radiator of the driving system is influenced. For example, in the high-temperature weather in summer, the ambient temperature outside the vehicle is greater than the preset ambient temperature, and the vehicle-mounted air conditioner adopts the internal circulation mode for refrigeration, so that the difference between the ambient temperature outside the vehicle and the ambient temperature inside the vehicle is greater than the preset difference, the comfort of the environment inside the vehicle is improved, and the ambient temperature outside the vehicle is judged to meet the preset temperature condition at the moment. When the vehicle-mounted air conditioner is in the internal circulation mode for refrigeration for a long time, a user in the vehicle may have a fresh air demand to trigger an external circulation instruction of the air conditioner, for example, a driver presses an external circulation button of the air conditioner to introduce fresh air, or automatically triggers the external circulation instruction of the air conditioner, at this time, step S10 and subsequent steps can be executed to obtain the temperature of a radiator of a vehicle driving system, and the opening degree of an air door of the vehicle air conditioner is adjusted according to the temperature of the radiator, so that the internal circulation and external circulation air volume of the vehicle air conditioner are controlled, the variation amplitude of the heat dissipation capacity of a condenser is further controlled, and the influence of the variation of the heat dissipation capacity of the condenser on the heat dissipation of a radiator of the driving system is reduced.
In addition, an embodiment of the present invention also provides a vehicle, including: the control method of the vehicle air conditioner comprises a memory, a processor and a control program of the vehicle air conditioner, wherein the control program of the vehicle air conditioner is stored on the memory and can run on the processor, and the control program of the vehicle air conditioner realizes the steps of the control method of the vehicle air conditioner according to the various embodiments when being executed by the processor.
