Fig. 1 is a flowchart of a control method of a heat pump air conditioner according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, obtaining a plurality of control parameters, wherein the plurality of control parameters comprise: the plurality of control parameters includes: the system comprises a mode parameter, an environment parameter, a vehicle state parameter and a heat pump air conditioner parameter, wherein the mode parameter is used for representing a refrigeration mode or a heating mode of the heat pump air conditioner.
Specifically, the vehicle may be an electric vehicle, the heat pump air conditioner may be a vehicle air conditioner installed on the electric vehicle, and a sensor may be installed on the installed electric vehicle so as to acquire a plurality of control parameters.
And step S104, obtaining the target frequency of the compressor of the heat pump air conditioner according to the plurality of control parameters.
And step S106, controlling the compressor to work according to the target frequency.
In an optional scheme, in order to control the heat pump air conditioner on the electric vehicle, all control parameters of the heat pump air conditioner and all control parameters of a vehicle environment where the heat pump air conditioner is located may be obtained, a target frequency of a compressor of the heat pump air conditioner may be determined according to the obtained plurality of control parameters, and an operating frequency of the compressor may be controlled according to the obtained target frequency. Furthermore, when one control parameter fails, the operating frequency of the compressor may be controlled by the other control parameters.
According to the embodiment of the invention, the control parameters are obtained, the target frequency of the compressor of the heat pump air conditioner is obtained according to the control parameters, and the compressor is controlled to work according to the target frequency, so that the compressor is controlled, the technical effects of improving the control speed and the reliability of the compressor and enabling the heat pump air conditioner to be more intelligent are achieved, and the technical problems that in the prior art, the heat pump air conditioner controls the frequency of the compressor only through a single mode of heat pump air conditioner parameter control, the control speed is low and the reliability is poor are solved.
Optionally, in the foregoing embodiment of the present invention, in step S104, obtaining the target frequency of the compressor of the heat pump air conditioner according to the plurality of control parameters includes: acquiring frequency ranges corresponding to a plurality of control parameters, wherein the frequency ranges corresponding to the control parameters are different; and obtaining the target frequency of the compressor of the heat pump air conditioner according to the frequency ranges corresponding to the control parameters.
In an alternative scheme, frequency limits are preset for each type of parameters, and the frequency range of the compressor corresponding to each type of parameters is different, and the frequency range decreases from the first type of parameters to the fourth type of parameters layer by layer, for example, the frequency range corresponding to the first type of parameters is 0-80 Hz; the frequency range corresponding to the second type of parameters is 0-60 Hz; the frequency range corresponding to the third type of parameters is 0-40 Hz; the fourth type of parameter corresponds to a frequency range of 40 Hz. The target frequency of the compressor can be obtained by a control method of direct fuzzy adjustment and indirect micro adjustment according to the frequency ranges corresponding to the control parameters.
Optionally, in the above embodiment of the present invention, obtaining the target frequency of the compressor of the heat pump air conditioner according to the frequency ranges corresponding to the plurality of control parameters includes: and acquiring the intersection of the frequency ranges corresponding to the control parameters to obtain the target frequency.
In an alternative scheme, direct control may be preferentially performed through each classification parameter, then indirect control is performed through parameter superposition, a frequency range F1 is defined according to a first class of parameters, a frequency range F2 is defined according to a second class of parameters, a frequency range F3 is further defined according to a third class of parameters, and finally, through the frequency ranges defined three times in the previous time, under the condition that the heat pump air conditioning parameters are met in the range, a target frequency F4 of the compressor is calculated through superposition of the three previous classes of parameters, wherein F3 is not less than F2 is not less than F1, that is, the intersection of the frequency ranges corresponding to each control parameter may be calculated, so that the target frequency is obtained. Therefore, even if one kind of parameters fails, the definition of other parameters is not influenced, and the frequency of the compressor can be adjusted within the response range, so that the phenomenon that the compressor is directly protected and stopped is avoided.
Through the scheme, the compressor frequency can be controlled more quickly and accurately by carrying out advanced fuzzy regulation and then micro regulation.
Optionally, in the above embodiment of the present invention, obtaining the target frequency of the compressor of the heat pump air conditioner according to the frequency ranges corresponding to the plurality of control parameters includes: acquiring a first control parameter which changes in a plurality of control parameters; and obtaining the target frequency according to the frequency range corresponding to the first control parameter and other control parameters of the plurality of control parameters except the first control parameter.

Because each type of parameter can only define a frequency range and cannot be accurate to an actual frequency, the compressor frequency can be directly subjected to fuzzy control according to the frequency range of the compressor, and then comprehensive judgment is performed according to the unchanged control parameters to accurately control the compressor frequency.
Through the scheme, the advantage of high response speed can be achieved by directly controlling the frequency of the compressor, but the defect of inaccurate control exists.
Optionally, in the foregoing embodiment of the present invention, when the first control parameter is multiple, obtaining the target frequency according to the frequency range corresponding to the first control parameter and other control parameters of the multiple control parameters except the first control parameter includes: obtaining the frequency corresponding to each first control parameter according to the frequency range corresponding to each first control parameter and other control parameters; and taking the frequency corresponding to each first control parameter as a target frequency according to a preset execution sequence.
Specifically, the preset execution sequence may be to execute a first type of parameter, that is, a mode parameter, then execute a second type of parameter, that is, an environmental parameter, further execute a third type of parameter, that is, a vehicle state parameter, and finally execute a fourth type of parameter, that is, a heat pump air conditioner parameter.
In an alternative scheme, when a plurality of control parameters are changed, a target frequency may be obtained according to a frequency range corresponding to each type of parameter and the unchanged parameter in sequence from the first type of parameter to the fourth type of parameter, and the compressor is controlled according to the target frequency.
Optionally, in the foregoing embodiment of the present invention, in step S104, obtaining the target frequency of the compressor of the heat pump air conditioner according to the plurality of control parameters includes: superposing the plurality of control parameters to obtain superposed control parameters; acquiring the frequency corresponding to the superposed control parameters; and determining the frequency corresponding to the superposed control parameters as a target frequency.
In an alternative scheme, a plurality of control parameters can be overlapped layer by layer, and finally, the frequency of the compressor is precisely controlled through the heat pump air conditioning system. For example, the acquired control parameters are a refrigeration mode, an in-vehicle temperature, an out-vehicle temperature, a set temperature, an air intake state without internal circulation, high windshield information, a temperature parameter and a pressure parameter, the acquired control parameters are superposed, and the state generated after superposition is as follows: and under certain parameters of the internal and external temperature of a certain vehicle, the refrigeration mode of the air conditioner, the internal circulation high windshield and the air conditioner, the target frequency is obtained in order to meet a certain set temperature in the vehicle.
Through the scheme, the frequency of the compressor can be controlled more comprehensively and accurately by superposing different parameters. But has the disadvantage of slow control speed.
Optionally, in the above embodiment of the present invention, before the step S102, before acquiring the plurality of control parameters, the method further includes: acquiring a plurality of parameters of a heat pump air conditioner and a vehicle in which the heat pump air conditioner is positioned; classifying the parameters to obtain a plurality of control parameters, wherein each control parameter comprises: at least one parameter; and obtaining a frequency range corresponding to each control parameter according to at least one parameter contained in each control parameter.
Optionally, in the foregoing embodiment of the present invention, the mode parameter includes: a cooling mode or a heating mode, and the environmental parameters comprise: the temperature inside the vehicle, the temperature outside the vehicle and the set temperature, and the vehicle state parameters comprise: air inlet state, windshield information, speed of a motor vehicle information, sunshine parameter, heat pump air conditioner parameter includes: temperature parameters, pressure parameters, and load parameters.
In an optional scheme, all the acquired parameters can be classified into four types, wherein the first type of parameters are also called mode parameters and mainly comprise a refrigeration or heating mode of a heat pump air conditioner; the second type of parameters are also called environmental parameters and mainly comprise the temperature inside the vehicle, the temperature outside the vehicle and the set temperature; the third kind of parameters are also called vehicle state parameters, and mainly comprise air inlet states, windshield information, vehicle speed and sunshine parameters and the like; the fourth type of parameters are also called heat pump air conditioning parameters, and mainly comprise temperature parameters, pressure parameters, load power and the like. The frequency range corresponding to each control parameter may be defined according to the parameter included in each control parameter, for example, in the first type of parameter, different frequency ranges may be defined according to different cooling or heating modes; in the second type of parameters, different frequency ranges can be defined according to the inner ring temperature, the outer ring temperature and the set temperature; in the third type of parameters, different frequency ranges are defined according to the vehicle state parameters, the windshield information and the vehicle speed; in the fourth type of parameters, different frequency ranges are defined according to the condition of the air conditioner of the human pump, temperature protection, high-voltage protection, current protection and the like.

For example, the running frequency range of the compressor of the heat pump air conditioner of the electric automobile is 0-100 Hz; in the first type of parameters, the frequency range corresponding to the preset refrigeration mode is 0-80Hz, the frequency range corresponding to the preset heating mode is 0-100 Hz, and when the refrigeration mode is obtained, F1 is defined to be 0-80 Hz; in the second type of parameters, different frequency ranges corresponding to different preset environment working conditions are different, and when the obtained temperature outside the vehicle is 40 ℃, F2 is defined to be 0-60 Hz; in the third type of parameters, different vehicle states also influence the frequency range, and F3 is defined to be 0-40Hz when the inner circulation and the lowest windshield are obtained; in the fourth type of parameters, according to the above-mentioned predetermined limited operation of 40Hz, and the initial value of F4 is 40Hz, if high pressure is generated during the operation, the frequency of the compressor F4 is changed, for example, the frequency is reduced to 35Hz, and if the heat pump air conditioner is normal, F4 is 35 Hz. After a period of operation, if the wind gear in the third type of parameters changes and changes from the lowest wind gear to the high wind gear, the frequency definition F3 preferably responds to 0-50 Hz, F4 also changes to 50Hz, and when the fourth type of parameters are determined to have no parameter protection, F4 is equal to 50 Hz.
