step S102: when the air conditioner is started, the air outlet grille is controlled to rotate to the maximum air outlet angle.
Referring to the schematic diagram of the air outlet grille shown in fig. 2a and the side view of the air outlet grille shown in fig. 2b, a plurality of rotatable air outlet grilles are arranged at the air outlet of the outer fan of the air conditioner, the air outlet angle of the air outlet grille is an included angle α between the air outlet grille and the vertical direction, the rotation range of the air outlet angle α of the air outlet grille is 0-90 °, when the air outlet angle α is 0 °, the air outlet angle is the minimum, the grille is in a closed state, and air cannot be exhausted; when the air outlet angle alpha is 90 degrees, the air outlet angle is the maximum air outlet angle, and air outlet is smooth. When the air conditioner is started in a refrigerating mode or a heating mode, the air outlet angle of the air outlet grille is controlled to be opened from 0 degree to 90 degrees at the maximum air outlet angle.
Step S104: and when the air outlet grille operates at the maximum air outlet angle for a first preset time length, detecting the operation mode of the air conditioner.

The value range of the first preset duration may be 1 to 3min, and the preferred value is 1min.
Step S106: when the operation mode is the heating mode, the temperature of the inner disc and the exhaust temperature are monitored, and the air outlet angle of the air outlet grille is controlled according to the temperature of the inner disc and the exhaust temperature.
When the operation mode of the air conditioner is a heating mode, the inner disc temperature TE and the exhaust temperature TP are respectively monitored in real time based on the temperature sensor, so that the operation load of the air conditioner during the operation period can be detected according to the inner disc temperature TE and the exhaust temperature TP, the air outlet angle of the air outlet grille is adjusted according to the operation load of the air conditioner, the air outlet static pressure of the outer fan is changed by changing the air outlet angle of the air outlet grille, the heat exchange of the outdoor unit is controlled, and the effect that the system pressure can be reduced by the outer fan without stopping when the high pressure of a heating mode system is high is achieved.

In an embodiment, in order to improve the operation reliability of the air conditioner, the embodiment provides an implementation manner of controlling the air outlet angle of the air outlet grille based on the inner disc temperature and the exhaust temperature, and the following steps (1) to (3) may be specifically referred to:
step (1): and when the temperature of the inner disc is less than or equal to a first preset temperature, controlling the air outlet grille to keep the maximum air outlet angle.
The temperature of the inner disc is periodically judged, when the temperature of the inner disc is less than or equal to a first preset temperature, the temperature of the inner disc is low, the heating load and the high pressure of the air conditioning system are low, the pressure of the system does not need to be reduced, and the air outlet grille is controlled to continuously keep the maximum air outlet angle of 90 degrees unchanged.
Step (2): when the inner tray temperature is larger than or equal to the second preset temperature, the target air outlet angle of the air outlet grille is periodically calculated based on the inner tray temperature and the exhaust temperature, and when the target air outlet angle is a positive value, the air outlet grille is controlled based on the target air outlet angle.
The second preset temperature is higher than the first preset temperature, and the calculation formula of the target air outlet angle is as follows: α = α 0 (1 + K1+ K2), alpha is the target air-out angle, alpha 0 For the current air outlet angle of the air outlet grille, K1 and K2 are correction coefficients, K1 is related to the temperature of the inner disc, K2 is related to the exhaust temperature, and the correction coefficient K1 is less than 0.
The second preset temperature TG may have a value ranging from 57 to 59 ℃, the first preset temperature TG may have a value ranging from 2 ℃ to 57 ℃.
When the inner disc temperature is greater than or equal to the second preset temperature, the heating operation load is high, the system pressure needs to be controlled to be reduced, the target air outlet angle of the air outlet grating is calculated every 10s based on the inner disc temperature and the exhaust temperature, when the calculated target air outlet angle is greater than 0, the effect of reducing the system pressure can be achieved by adjusting the air outlet angle of the air outlet grating, and the air outlet grating is controlled to be controlled from the current air outlet angle alpha 0 And rotating to a target air outlet angle alpha. Therefore, the air outlet angle of the air outlet grille is periodically adjusted, the air outlet angle of the air outlet grille is controlled to be periodically reduced, the pressure of the system is reduced, and the outer fan does not need to be controlled to stop.
When the temperature of the inner disc is higher, the air outlet angle of the air outlet grille is periodically corrected to be reduced according to the temperature of the inner disc and the exhaust temperature, so that the purpose of controlling the air outlet static pressure of an air conditioner external unit to be increased when the heating operation load and the system pressure are higher is achieved, the system pressure is reduced, the external fan does not need to be stopped, and the operation reliability and stability of the air conditioner are improved.
In one embodiment, the correction factor K1 is inversely related to the inner coil temperature difference Δ T, which is the difference between the inner coil temperature and the second predetermined temperature. In a specific embodiment, when 0 ℃ <. DELTA.T.ltoreq.1 ℃, K1= -a%; when the temperature is 1 ℃ and is less than delta T and less than or equal to 2 ℃, K1 is not less than-b percent; when the temperature is higher than 2 ℃ and less than or equal to delta T and less than or equal to 3 ℃, K1 is not less than-c percent; when DeltaT is more than 3 ℃, K1= -d%; a < b < c < d.
Calculating the difference value between the current inner coil temperature and the second preset temperature every 10s, recording the difference value as the inner coil temperature difference delta T = TE-TG ℃, wherein the correction coefficient K1 is influenced by the inner coil temperature difference delta T, the larger the inner coil temperature difference delta T is, the smaller the value of the correction coefficient K1 is, because K1 is less than 0, namely the larger the inner coil temperature difference delta T is, the larger the air outlet angle reduction speed of the air outlet grating is, the smaller the air outlet angle reduction speed of the air outlet grating can be increased when the inner coil temperature difference is larger, and the pressure of the unit is rapidly reduced to avoid high-voltage protection of the unit.
In a specific embodiment, the value of the correction coefficient K1 of the outlet air angle of the outlet air grille can refer to a relation table between the temperature difference Δ T of the inner coil and the correction coefficient K1 as shown in the following table one:
table-table relationship table between temperature difference delta T and correction coefficient K1 of inner coil
| Temperature difference delta T of inner coil pipe | Target grid angle correction coefficient K1 |
| 0℃＜△T≤1℃ | -2％ |
| 1℃＜△T≤2℃ | -5％ |
| 2℃＜△T≤3℃ | -8％ |
| △T＞3℃ | -10％ |
In one specific embodiment, the correction coefficient K2 is inversely related to the change rate of the exhaust temperature, and when the change rate of the exhaust temperature is less than 0, the correction coefficient K2 is greater than 0, and when the change rate of the exhaust temperature is greater than or equal to 0, the correction coefficient K2 is less than 0.
Detecting a rate of change d (Δ TP)/d (t) of the exhaust temperature TP, e.g., 5S exhaust temperature from 70 ℃→ 75 ℃, such that d (Δ TP)/d (t) has a value of 1 ℃/S, and in one embodiment, K2= x1% when d (Δ TP)/d (t) < -1; when-1 ≦ d ([ delta ] TP)/d (t) < -0.5, K2= x2%; when-0.5 ≦ d ([ Delta ] TP)/d (t) < 0, K2= x3%; when d (Delta TP)/d (t) < 0.5 is more than or equal to 0, K2= -x3%; when d (Delta TP)/d (t) < 1 is more than or equal to 0.5, K2= -x2%; when d ([ Delta ] TP)/d (t) > 1, K2= -x1%; x1 > x2 > x3.
Calculating the change rate d (delta TP)/d (t) of the exhaust temperature every 10s, when the operation load of the unit is high, the temperature of the inner disc is high, the rising speed of the exhaust temperature is high, K2 is a correction coefficient when the change of the exhaust temperature is high, the correction coefficient K2 is in negative correlation with the change rate of the exhaust temperature by setting the correction coefficient K2, when the change rate of the exhaust temperature is less than 0, the correction coefficient K2 is more than 0, when the change rate of the exhaust temperature is more than or equal to 0, the correction coefficient K2 is less than 0, namely when the absolute value of the change rate of the exhaust temperature is larger, the absolute value of the correction coefficient K2 is larger, when the change rate of the exhaust temperature is larger, the adjusting speed of the air outlet grille is increased, the adjusting speed of the air outlet grille is changed along with the change rate of the exhaust temperature, and the pressure of the air conditioning system can be reduced without controlling the stop of an external fan.

The first air outlet angle is smaller than the maximum air outlet angle, the value range of the first air outlet angle can be 40-50 degrees, and the preferred value is 45 degrees. Because the minimum air outlet angle of the air outlet grille is 0 degree, when the calculated target air outlet angle is less than 0 degree, the effect of reducing the system pressure cannot be achieved by controlling the air outlet angle of the air outlet grille, and the air outlet grille is controlled to rotate to the first air outlet angle in 5s and is kept.
Step 2): and controlling the opening degree of an expansion valve of the indoor unit to increase at a first preset rate, detecting the change rate of the temperature of the inner disc, and controlling the opening degree of the expansion valve of the indoor unit to increase at a second preset rate when the change rate of the temperature of the inner disc is less than 0.
The second predetermined rate is less than the first predetermined rate. And when the target air outlet angle is less than 0, controlling the air outlet angle of the air outlet grille to be incapable of achieving the effect of reducing the system pressure, and controlling the opening of an electronic expansion valve of the indoor unit to be increased. The opening degree of the expansion valve of the indoor unit is controlled to increase at a first preset rate, wherein the first preset rate can be 2 degrees/S, and the change value of the inner disc temperature within a certain time, such as the change value TE of the inner disc temperature within 2S, is calculated during the increase process of the opening degree of the expansion valve of the indoor unit t+2 -TE t When TE t+2 -TE t If the temperature of the inner disc is lower than 0 degree, the temperature of the inner disc begins to be lowered, the increasing speed of the opening degree of the expansion valve of the indoor unit can be controlled to be lowered, the first preset speed is lowered to a second preset speed, and the second preset speed can be 1 degree/S.
When the target air outlet angle is a negative value, the opening of the expansion valve of the indoor unit is controlled to be increased, and when the air outlet angle of the air outlet grille cannot reduce the system pressure, the opening of the electronic expansion valve is controlled to assist in adjusting the system pressure, so that the external fan does not need to be controlled to stop, and the unit is effectively protected.
Step 3): and when the temperature of the inner disc is reduced to be less than or equal to a first preset temperature, controlling the opening of the expansion valve of the indoor unit to stop increasing.
In the process of controlling the expansion valve of the indoor unit to increase, the temperature of the inner disc generally gradually decreases, the temperature of the inner disc is detected in real time, and when the temperature of the inner disc decreases to be less than or equal to a first preset temperature, the temperature of the inner disc obviously decreases, the pressure of a system obviously decreases, the running load of the system decreases, and the opening of the expansion valve of the indoor unit is controlled to stop increasing.
And step 4): when the temperature of the inner disc is reduced to be less than or equal to a third preset temperature, the expansion valve of the indoor unit is controlled to recover the original opening before increasing, and the air outlet grille is controlled to rotate to the maximum air outlet angle.
The third preset temperature is lower than the first preset temperature, and the third preset temperature may be the first preset temperature TG-5 ℃. When the temperature of the inner disc is continuously reduced to be less than or equal to a third preset temperature, the system operation load is recovered to be normal, the system pressure is stable, the opening degree of the expansion valve of the indoor unit is controlled to be recovered to the original opening degree before the opening degree is increased (namely, the opening degree when the target air outlet angle is less than 0 is obtained through calculation), the air outlet grille is controlled to be recovered to the maximum air outlet angle of 90 degrees, the next circulation is carried out, and the step S108 is executed.
The opening of the expansion valve of the indoor unit is controlled to stop increasing and return to the original opening when the temperature of the inner disc is obviously reduced, so that the air conditioner is controlled to return to normal operation after the system pressure is obviously reduced and the system operation load is reduced, and the heating comfort of the air conditioner is ensured.
In an embodiment, the method for controlling an air outlet grille of an air conditioner provided in this embodiment further includes: and when the air conditioner is shut down, the air outlet grille is controlled to be closed after a second preset time.
When the air conditioner is turned off in the cooling mode, the value range of the second preset time period may be 10 to 30min, and the preferred value is 30min. When the operation mode of the air conditioner is a refrigeration mode, after the air conditioner is turned off by a user, in order to dissipate heat in the grille as much as possible, the air outlet grille keeps a second preset duration at the maximum air outlet angle after the air conditioner is turned off, then the air outlet grille is controlled to be closed to 0 degree, the air outlet grille is controlled to be closed to 0 degree after the air conditioner is closed for a period of time, and external dust can be prevented from entering the air conditioner.
When the air conditioner is turned off in the heating mode, the value of the second preset duration may be in the range of 5-10 min, preferably 10min. When the operation mode of the air conditioner is the heating mode, after the air conditioner is closed by a user, the air outlet grille keeps the current air outlet angle and continues to operate for a second preset time, and then the air outlet grille is controlled to be closed to 0 degree so as to prevent external dust from entering the air conditioner.

The air outlet grille is closed to be 0 degree, so that external dust can be prevented from entering the air conditioner.
The air outlet angle of the air outlet grille is controlled by an outdoor unit of the air conditioner.
Step2, when the air conditioner is started up in a heating mode, the air outlet angle of the air outlet grille is opened from 0 degree to 90 degrees within 1min, and the air outlet angle of the air outlet grille is adjusted according to the operation load of the air conditioner during operation:

(2) If the temperature TE of the coil pipe of the inner machine is more than or equal to TG ℃, the running load of the machine set is judged to be too high, the air outlet angle of the air outlet grille is controlled to be small, the air outlet static pressure of the air conditioner outer machine is increased, and the system pressure can be reduced. The grid target control angle formula is as follows:
α＝α 0 (1+K1+K2)
k1 is related to the inner disc temperature and K2 is related to the exhaust gas temperature. When the load is high, not only the inner disk temperature is high, but also the exhaust temperature rises quickly. Therefore, K1 is used to indicate the correction coefficient when the inner disc temperature is high, and K2 is used to indicate the correction coefficient when the exhaust temperature changes rapidly.
The minimum angle of the grid blades is 0, if the calculated target angle alpha of the air outlet grid is less than 0 in the adjusting process, the following control is carried out:
step1: and adjusting the air outlet angle of the air outlet grille, and rotating the air outlet grille to 45 degrees in 5s and keeping the angle.
step2: and adjusting the opening of the electronic expansion valve, wherein the opening is determined in the following way:
P＝P+△P

Step3: and when the temperature TE of the inner disc is less than or equal to TG-2 ℃, the system load is reduced, and the opening of the electronic expansion valve is controlled to stop increasing.
Step4: and if the temperature TE of the inner disc is less than or equal to TG-5 ℃, controlling the electronic expansion valve to recover the opening before adjustment, controlling the air outlet angle of the air outlet grille to be opened to 90 ℃ and entering the next cycle.
Note: in the operation process, the air outlet angle of the air outlet grille is judged by the temperature of the inner disc to judge whether to enter the opening regulation, and the change rate of the exhaust temperature is only one compensation for the judgment of the opening regulation size. The target air outlet angle of the air outlet grille is updated every 10S, and the value range of TG is 57-59 DEG C
(3) If the inner disk temperature TG-2 ℃ is less than TE and less than TG, the state of TE before the interval is maintained to be unchanged.
