The air conditioner provided by the embodiment of the invention comprises an indoor unit and an outdoor unit. The outdoor unit is internally provided with a compressor which is a variable frequency compressor. The indoor unit is internally provided with two fans for blowing air indoors, namely a first fan and a second fan, and the two fans are configured to independently operate in a controlled manner so as to realize multiple blowing modes of the indoor unit. For example, when the air conditioner is in operation, one fan can be started independently, or two fans can be started simultaneously, and when the two fans are started simultaneously, the rotating speeds of the two fans can be the same or different, and the air supply directions can be the same or different.
And when the rotating speeds of the first fan and the second fan are different, controlling the differential air supply.
Taking the case that the rotating speed of the first fan is greater than that of the second fan, the first fan can rotate at a high speed at the moment, the second fan can rotate at a medium speed or a low speed, or the first fan can rotate at a medium speed, the second fan can rotate at a low speed, and the difference value occurs between the rotating speeds of the first fan and the second fan, so that differential air supply control is realized.

The air conditioner further comprises a throttle valve arranged between the evaporator and the condenser.
The air conditioner is also provided with a processor, a temperature sensor and a detection device, wherein the temperature sensor is used for detecting the temperature of the external environment, and the detection device is used for acquiring the rotating speeds of the first fan and the second fan. The processor is connected with the temperature sensor, the first fan, the second fan, the compressor and the throttle valve. The temperature sensor and the detection device send detection results to the processor, and the processor is connected with the compressor and the throttle valve to control the operation of the compressor and the throttle valve.
As shown in fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, the control method including steps S01 and S02.
In step S01, the processor performs determination of the limit frequency mb_hz of the compressor according to the following formula when the differential air supply control is operated in the heating mode:
mb_Hz＝Hz1+(ah*Hz1)/2+(T–Tao)*ch；
the rotational speed of the first fan is unequal to the rotational speed of the second fan in the differential air supply control, hz1 is the minimum value between an indoor frequency value and an outdoor frequency limit frequency determined according to an outdoor environment temperature, the indoor frequency value is a compressor frequency H1X determined according to an indoor target temperature (namely a set temperature), X is a coefficient smaller than or equal to 1, T is larger than or equal to 5 ℃ and smaller than or equal to 6.5 ℃, tao is the outdoor environment temperature, and units are the temperatures of ah and ch. In order to avoid arithmetic logic errors, only the numerical values of Hz1 and T, tao are used for calculation in the actual operation process, and the final calculation result takes Hz as a unit.
In step S02, the processor controls the operating frequency of the compressor to be less than or equal to the limit frequency mb_hz.
In determining the limit frequency mb_hz of the compressor, hz1 is first determined. Hz1 is the minimum between the indoor frequency value and the outdoor frequency limit frequency.
The indoor frequency value is equal to the product of H1 and X. H1 is the compressor frequency determined from the indoor target temperature. The indoor target temperature may be a temperature input by a user, such as a temperature that the user sets by operating an air conditioner remote controller or an operation panel on the indoor unit, which needs the air conditioner to reach. There is a correspondence between the indoor target temperature and the operating frequency of the compressor, which can be obtained by looking up a table. Therefore, the frequency H1 of the compressor corresponding to the indoor target temperature can be obtained through table lookup corresponding to different indoor target temperatures. And multiplying H1 by X, and correcting H1 to obtain an indoor frequency value so as to further ensure safe operation of the compressor.
There is also a correspondence between the outdoor ambient temperature and the frequency limit of the compressor, which can also be obtained by looking up a table. Therefore, the frequency limiting frequency of the compressor corresponding to the outdoor environment temperature, namely the outdoor frequency limiting frequency, can be obtained through table lookup corresponding to different outdoor environment temperatures.
And setting coefficients ah and ch to obtain the limit frequency mb_Hz. When the air conditioner executes differential air supply control, differential compensation is performed on the operation frequency of the compressor, so that the operation frequency of the compressor is matched with the differential operation of the first fan and the second fan, the outdoor environment temperature and the indoor target temperature, and the operation performance of the air conditioner is improved.
After the limit frequency mb_hz of the compressor is obtained, the compressor is controlled to operate at a frequency less than or equal to the limit frequency mb_hz.
Optionally, the limit frequency mb_hz of the compressor also satisfies: the mb-Hz is more than or equal to Hz1, and the power of the compressor is ensured, thereby increasing the heating speed of the air conditioner.
Alternatively, mb_hz=int (mb_hz), facilitating control of the compressor.
In the heating mode, in the differential air supply control, for mb_hz calculation, the preset time is executed once every interval, for example, the preset time may be 1min; during the action of the compressor oil return platform, the differential air supply control is not executed; and (3) PID valve regulating control, wherein the differential frequency of the compressor is not compensated during the reference opening degree maintaining period.
As shown in fig. 2, the embodiment of the present disclosure provides another control method for an air conditioner, including step S10, step S01, and step S02.
Step S10, under a heating mode, when differential air supply control is operated, the processor determines X according to the outdoor environment temperature and the rotating speeds of the first fan and the second fan;
in step S01, the processor performs determining the limit frequency mb_hz of the compressor according to the following formula:
mb_Hz＝Hz1+(ah*Hz1)/2+(T-Tao)*ch；
the rotating speed of the first fan and the rotating speed of the second fan in the differential air supply control are unequal, hz1 is the minimum value between an indoor frequency value and an outdoor frequency limiting frequency determined according to outdoor environment temperature, the indoor frequency value is the compressor frequency H1X determined according to indoor target temperature, X is a coefficient smaller than or equal to 1, T is larger than or equal to 5 ℃ and smaller than or equal to 6.5 ℃, tao is the outdoor environment temperature, and ah and ch are coefficients.
In step S02, the processor controls the operating frequency of the compressor to be less than or equal to the limit frequency mb_hz.
In step S10, X is determined according to the outdoor environment temperature and the rotational speeds of the first fan and the second fan, so that the value of X is matched with the outdoor environment temperature and the rotational speeds of the first fan and the second fan, and the limit frequency mb_hz of the compressor is matched with the outdoor environment temperature and the rotational speeds of the first fan and the second fan, so that the limit frequency mb_hz of the compressor is more accurate.
In step S10, the value of X decreases with an increase in the outdoor ambient temperature.
The greater the outdoor ambient temperature, the less operating frequency and thus X, the less the compressor needs to operate.
X increases with increasing rotational speed of the first fan and the second fan.
The higher the rotation speed of the first fan and the second fan is, the larger the value of X is, so that the limit frequency mb_Hz of the compressor is higher, and the running performance of the air conditioner is ensured.
As shown in fig. 3, an embodiment of the present disclosure provides another control method for an air conditioner, including steps S20, S01, and S02.
Step S20, under a heating mode, when differential air supply control is operated, determining ah according to the rotating speeds of the first fan and the second fan;
in step S01, the processor performs determining the limit frequency mb_hz of the compressor according to the following formula:
mb_Hz＝Hz1+(ah*Hz1)/2+(T-Tao)*ch；；
the rotating speed of the first fan and the rotating speed of the second fan in the differential air supply control are unequal, hz1 is the minimum value between an indoor frequency value and an outdoor frequency limiting frequency determined according to outdoor environment temperature, the indoor frequency value is the compressor frequency H1X determined according to indoor target temperature, X is a coefficient smaller than or equal to 1, T is larger than or equal to 5 ℃ and smaller than or equal to 6.5 ℃, tao is the outdoor environment temperature, and ah and ch are coefficients.
In step S02, the processor controls the operating frequency of the compressor to be less than or equal to the limit frequency mb_hz.
In step S20, ah is determined according to the rotation speeds of the first fan and the second fan, so that the value of ah is matched with the rotation speeds of the first fan and the second fan, and therefore the limit frequency mb_hz of the compressor is matched with the rotation speeds of the first fan and the second fan, and the limit frequency mb_hz of the compressor is more accurate.
As shown in fig. 4, the embodiment of the present disclosure provides another control method for an air conditioner, including step S30, step S01, and step S02.
Step S30, under a heating mode, the processor determines ch according to the outdoor environment temperature when the differential air supply control is operated;
in step S01, the processor performs determining the limit frequency mb_hz of the compressor according to the following formula:
mb_Hz＝Hz1+(ah*Hz1)/2+(T-Tao)*ch；
the rotating speed of the first fan and the rotating speed of the second fan in the differential air supply control are unequal, hz1 is the minimum value between an indoor frequency value and an outdoor frequency limiting frequency determined according to outdoor environment temperature, the indoor frequency value is the compressor frequency H1X determined according to indoor target temperature, X is a coefficient smaller than or equal to 1, T is larger than or equal to 5 ℃ and smaller than or equal to 6.5 ℃, tao is the outdoor environment temperature, and ah and ch are coefficients.
In step S02, the processor controls the operating frequency of the compressor to be less than or equal to the limit frequency mb_hz.
In step S30, ch is determined according to the outdoor environment temperature, so that the value of ch is matched with the outdoor environment temperature, and the limit frequency mb_hz of the compressor is matched with the outdoor environment temperature, so that the limit frequency mb_hz of the compressor is more accurate.
In step S30, the value of ch decreases as the outdoor ambient temperature increases.
In the heating mode, the larger the outdoor environment temperature is, the smaller the value of ch is, so that the limit frequency mb_Hz of the compressor is smaller, and the running performance of the air conditioner is ensured.
Taking the change of ch along with the outdoor environment temperature as an example, when Tao is smaller than T, T-Tao is larger than 0, the outdoor environment temperature is lower, ch is larger, mb_Hz obtained according to mb_Hz=Hz 1+ (ah+Hz 1)/2+ (T-Tao) ch is larger, the running frequency of the compressor is larger, and the control of the normal running frequency of the compressor is met; when Tao is more than T, T-Tao is less than 0, the outdoor environment temperature is higher, ch is smaller, mb_Hz obtained according to mb_Hz=Hz 1+ (ah+Hz 1)/2+ (T-Tao) ch is smaller, the running frequency of the compressor is smaller, and the control of the normal running frequency of the compressor is met.
In one particular air conditioner model, values of ah, ch and X at different outdoor ambient temperatures, first fan and second fan speeds are shown in tables 1-3, respectively.
TABLE 1
TABLE 2
| Outdoor ambient temperature | ≤0℃ | 0～5℃ | ＞5℃ |
| ch value | 2.0 | 1.0 | 0.0 |

In step S01, the processor performs determination of the limit frequency mb_hz of the compressor according to the following formula when the differential air supply control is operated in the heating mode:
mb_Hz＝Hz1+(ah*Hz1)/2+(T-Tao)*ch；
the rotating speed of the first fan and the rotating speed of the second fan in the differential air supply control are unequal, hz1 is the minimum value between an indoor frequency value and an outdoor frequency limiting frequency determined according to outdoor environment temperature, the indoor frequency value is the compressor frequency H1X determined according to indoor target temperature, X is a coefficient smaller than or equal to 1, T is larger than or equal to 5 ℃ and smaller than or equal to 6.5 ℃, tao is the outdoor environment temperature, and ah and ch are coefficients.
In step S02, the processor controls the operating frequency of the compressor to be less than or equal to the limit frequency mb_hz.
In step S40, the processor determines a target opening degree of the throttle valve according to the limit frequency mb_hz of the compressor and controls the throttle valve to operate at the target opening degree.
After the limit frequency of the compressor is determined, determining the target opening of the throttle valve according to the limit frequency of the compressor, and controlling the throttle valve to operate under the target opening, so that the operating opening of the throttle valve is matched with the limit frequency of the compressor, and the operating performance of the whole machine is further improved.
Step S40 includes: the target opening degree mb_pls of the throttle valve is determined according to the following formula:
mb_PLS＝PLS+(mb_Hz-Hz1)*bh；
PLS is the opening degree of the throttle valve before switching to the differential air blowing control, and bh is a coefficient of greater than 0 and less than or equal to 1.
Because of the unit Hz of Hz1 and mb_Hz, in order to avoid arithmetic logic errors, only the numerical values of Hz1 and mb_Hz are used for calculation in the actual operation process.
In addition to the differential air blow control, the air conditioner may perform non-differential air blow control, such as protection control, under which differential compensation is not performed for the frequency of the compressor. Taking the example that the air conditioner firstly runs the protection control and then switches from the protection control to the differential air supply control, PLS is the opening of the throttle valve when the protection control is executed.
In the differential air blowing control, both the first fan and the second fan are operated, and therefore, the opening degree of the throttle valve needs to be increased. The opening of the throttle valve is compensated with the formula mb_pls=pls+ (mb_hz-Hz 1) bh.
It will be appreciated that step S40 may also be located between step S01 and step S02.
As shown in fig. 6, an embodiment of the present disclosure provides another control method for an air conditioner, including the following steps.
Step S50, under a heating mode, the processor executes differential air supply control when the difference value between the indoor target temperature and the indoor current temperature is larger than a preset temperature threshold value;
step S10, under a heating mode, when differential air supply control is operated, the processor determines X according to the outdoor environment temperature and the rotating speeds of the first fan and the second fan;
step S20, under a heating mode, when differential air supply control is operated, determining ah according to the rotating speeds of the first fan and the second fan;
step S30, determining ch according to the outdoor environment temperature when the differential air supply control is operated in a heating mode;
in step S01, the processor performs determination of the limit frequency mb_hz of the compressor according to the following formula when the differential air supply control is operated in the heating mode:
mb_Hz＝Hz1+(ah*Hz1)/2+(T-Tao)*ch；
the rotating speed of the first fan and the rotating speed of the second fan in the differential air supply control are unequal, hz1 is the minimum value between an indoor frequency value and an outdoor frequency limiting frequency determined according to outdoor environment temperature, the indoor frequency value is the compressor frequency H1X determined according to indoor target temperature, X is a coefficient smaller than or equal to 1, T is larger than or equal to 5 ℃ and smaller than or equal to 6.5 ℃, tao is the outdoor environment temperature, and ah and ch are coefficients.
In step S02, the processor controls the operating frequency of the compressor to be less than or equal to the limit frequency mb_hz.
In step S40, the processor determines a target opening degree of the throttle valve according to the limit frequency mb_hz of the compressor and controls the throttle valve to operate at the target opening degree.
In step S60, the processor executes a protection control when the difference between the indoor target temperature and the indoor current temperature is less than or equal to a preset temperature threshold in the heating mode, and determines a limit frequency of the compressor according to the outdoor environment temperature in the protection control.
Wherein the order of steps S10, S20 and S30 may be interchanged.
In the heating mode, when the difference between the indoor target temperature and the indoor current temperature is larger than the preset temperature threshold, the indoor current temperature is lower, and rapid heating can be performed. Therefore, the differential air blowing control is operated at this time.
In the heating mode, when the difference between the indoor target temperature and the indoor current temperature is smaller than or equal to the preset temperature threshold, the indoor current temperature is higher, and rapid heating can be omitted. Therefore, the protection control is run at this time. In the protection control, the limit frequency of the compressor is determined according to the outdoor environment temperature, and the frequency of the compressor does not need differential compensation.
Optionally, step S50 includes:
when the difference value between the indoor target temperature and the indoor current temperature is larger than a preset temperature threshold value and smaller than a specified temperature threshold value, performing differential air supply control, wherein the rotating speed of the first fan is a first preset rotating speed, the rotating speed of the second fan is a second preset rotating speed, the first preset rotating speed is larger than the second preset rotating speed, and the specified temperature threshold value is larger than the preset temperature threshold value;
and when the difference value between the indoor target temperature and the indoor current temperature is greater than the specified temperature threshold value, performing differential air supply control, wherein the rotating speed of the first fan is a third preset rotating speed, the rotating speed of the second fan is a fourth preset rotating speed, the first preset rotating speed is smaller than the third preset rotating speed, and the second preset rotating speed is smaller than or equal to the fourth preset rotating speed.
For example, when the difference between the indoor target temperature and the indoor current temperature is greater than a preset temperature threshold and less than a specified temperature threshold, the second fan runs at a medium speed; when the difference between the indoor target temperature and the indoor current temperature is larger than the specified temperature threshold, the first fan operates at a high speed, and the second fan operates at a medium speed or a low speed.
In the protection control, when the differential air supply control command is received, the differential air supply command is not executed until the protection control is exited, namely the priority of the protection control is higher than that of the differential air supply control. In the differential air supply control, the operation frequency of the compressor is subjected to protection action on the basis of the existing differential air supply operation frequency, wherein the protection action means that the operation frequency of the compressor is slowly increased, and when the operation frequency is increased to at least one frequency between the existing operation frequency and the limiting frequency, the operation of the frequency is maintained for a preset time length, so that the compressor is protected; the time interval between two times of protruding before and after the differential air supply control is at least 30 seconds, namely the time interval between two times of entering the differential air supply is at least 30 seconds.
When the first fan performs the heating mode, the second fan also performs the heating mode.
