As a possible implementation manner, as shown in fig. 8, the method specifically includes the following steps:

s301, acquiring a first target air outlet temperature at the positive air outlet and a second target air outlet temperature at the top air outlet.

It should be noted that, in the present application, a mapping relationship between an indoor ambient temperature, an outdoor ambient temperature, an illumination intensity, and a set temperature and a first target outlet air temperature and a second target outlet air temperature is preset, when trying to obtain the first target outlet air temperature and the second target outlet air temperature of the air conditioner, the indoor ambient temperature, the outdoor ambient temperature, the illumination intensity, and the set temperature may be obtained, and then mapping is queried according to the obtained indoor ambient temperature, outdoor ambient temperature, illumination intensity, and set temperature, so as to determine the first target outlet air temperature and the second target outlet air temperature of the air conditioner.

Optionally, the indoor ambient temperature and the outdoor ambient temperature may be obtained by temperature sensors; acquiring illumination intensity through an illumination sensor; the air conditioner is controlled to read the set temperature input by the user, and then the first target air outlet temperature and the second target air outlet temperature of the air conditioner can be determined by inquiring the preset mapping relation.

S302, a first actual air outlet temperature at the positive air outlet of the air conditioner and a second actual air outlet temperature at the top air outlet are obtained.

Optionally, a first actual outlet air temperature at the front outlet air outlet of the air conditioner and a second actual outlet air temperature at the top outlet air outlet may be obtained by a temperature sensor.

S303, according to first actual air-out temperature and first target air-out temperature, acquire the first difference in temperature to according to second actual air-out temperature and second target air-out temperature, acquire the second difference in temperature.

Wherein, the first temperature difference and the second temperature difference can be positive number, negative number and zero.

For example, if the obtained first actual outlet air temperature is 23 ℃ and the first target outlet air temperature is 21 ℃, the two may be subtracted to obtain a first temperature difference of 23 ℃ to 21 ℃ ═ 2 ℃; if the obtained second actual outlet air temperature is 23 ℃ and the second target outlet air temperature is 24 ℃, the two temperatures can be subtracted to obtain a second temperature difference of-1 ℃ between 23 ℃ and 24 ℃.

S304, adjusting the rotating speed of the target fan to a target rotating speed according to the first temperature difference and the second temperature difference; wherein, the target fan is a first fan or a second fan.

It should be noted that, when trying to adjust the rotation speed of the target fan to the target rotation speed according to the first temperature difference and the second temperature difference, the target fan may be determined from the first fan and the second fan, the target rotation speed and the adjustment direction of the fan rotation speed may be determined according to the first temperature difference and the second temperature difference, and then the obtained rotation speed of the target fan may be adjusted to the target rotation speed according to the obtained target rotation speed and the adjustment direction.

Optionally, when the rotation speed of the target fan is attempted to be adjusted, the working states of the first heat exchange unit and the second heat exchange unit may be acquired to determine the target fan. If the inlet and the outlet of the first heat exchange unit corresponding to the first fan are identified to be closed, determining that the first fan is a target fan; and if the inlet and the outlet of the second heat exchange unit corresponding to the second fan are identified to be closed, determining that the second fan is the target fan.

Further, in this application, the mapping relation between the first temperature difference and the second temperature difference and the target rotating speed is preset, and when the target rotating speed is attempted to be obtained, the mapping relation between the preset first temperature difference and the preset second temperature difference and the target rotating speed can be inquired according to the obtained first temperature difference and the obtained second temperature difference, so that the target rotating speed is determined.

Further, the adjusting direction of the rotating speed of the fan can be determined according to the first temperature difference and the second temperature difference. If the first temperature difference and the second temperature difference are identified to be larger than 0, the adjustment direction of the rotating speed of the fan can be determined to be the rotating speed reduction; if the first temperature difference and the second temperature difference are identified to be less than 0, the adjustment direction of the rotating speed of the fan can be determined to be the rotating speed increasing; if the recognition deviation value is equal to 0, the fan can be controlled to maintain the current rotating speed.

At this time, the rotating speed of the target fan can be adjusted to the target rotating speed according to the obtained target fan, the target rotating speed and the adjusting direction. For example, when the inlet and outlet of the first heat exchange unit corresponding to the first fan is identified to be closed, the obtained deviation value is 2 ℃, and the rotating speed of the first fan can be reduced to 550r/min by inquiring the mapping relation and setting the target rotating speed to 550 r/min.

It should be noted that, before attempting to determine the target rotation speed of the target fan requiring rotation speed adjustment according to the first temperature difference and the second temperature difference, the first actual outlet air temperature and the second actual outlet air temperature may be first identified.

Optionally, after the first actual outlet air temperature and the second actual outlet air temperature are obtained, the first actual outlet air temperature and the second actual outlet air temperature may be subtracted from each other to obtain a difference value between the first actual outlet air temperature and the second actual outlet air temperature, and the difference value is marked as a third temperature difference. Further, after the third temperature difference is obtained, the third temperature difference can be compared with a preset temperature difference threshold, and if the third temperature difference is identified to not reach the preset temperature difference threshold, the fact that the actual air outlet temperature at the current positive air outlet is close to the actual air outlet temperature at the top air outlet, and the effect of multi-temperature wind sensation cannot be created is indicated, the target rotating speed of the target fan is further adjusted; if the third temperature difference is recognized to reach the preset temperature difference threshold value, the fact that the actual air outlet temperature at the current positive air outlet is obviously different from the actual air outlet temperature at the top air outlet is shown, the effect of multi-temperature wind sensation can be created, and then the current rotating speed of the target fan is maintained.

1. because this application can be after opening a heat transfer unit, through adjusting target fan rotational speed to target rotational speed, reduce because of closing the deviation between the actual air-out temperature that the heat transfer unit who one of them fan corresponds imports and exports the actual air-out temperature that leads to and the target air-out temperature to make the actual air-out temperature of positive air outlet department and top air outlet department be close respective target air-out temperature, thereby make the indoor environment that the air conditioner is located more stable, also can avoid the fluctuation of indoor environment simultaneously.

2. Because this application can be according to first difference in temperature and second difference in temperature, before the target rotational speed of the target fan of rotational speed is adjusted in the affirmation needs, still need adjust the actual temperature of air outlet well and top air outlet and detect, when the difference in temperature of two air outlets does not reach preset difference in temperature threshold value, through the target rotational speed of the target fan that the regulation needs to be adjusted, with the difference in temperature of two air outlets of increase, in order to ensure to build the effect of many warm wind feelings, make indoor user feel comfortable.

Further, after the target rotating speed of the target fan is adjusted according to the first temperature difference and the second temperature difference, the operation frequency of the compressor can be further reduced, so that the first actual air outlet temperature and the second actual air outlet temperature can be further ensured to be close to the first target air outlet temperature and the second target air outlet temperature respectively.

It should be noted that, when trying to reduce the operating frequency of the compressor, the operating frequency can be reduced to the preset operating frequency for the first time, so that the frequency of the compressor can be matched with the number of the heat exchange units, and then the step length of the reduction of the operating frequency is adjusted according to the first temperature difference and the second temperature difference until the first actual air outlet temperature and the second actual air outlet temperature can be respectively consistent with the first target air outlet temperature and the second target air outlet temperature. The preset operation frequency can be set according to actual conditions.

Furthermore, in the application, the mapping relation between the first temperature difference and the step length and the mapping relation between the second temperature difference and the step length are preset, and when the step length is tried to be obtained, the preset mapping relation between the first temperature difference and the step length and the preset mapping relation between the second temperature difference and the step length can be inquired according to the obtained first temperature difference and the obtained second temperature difference, so that the step length is determined. Wherein the step size is larger than 0.

Further, the adjustment direction of the step length can be determined according to the acquired first temperature difference and the acquired second temperature difference. If the first temperature difference and the second temperature difference are identified to be larger than the set difference value, the adjustment direction of the step length can be determined to be the frequency increase; if the first temperature difference and the second temperature difference are identified to be smaller than the set difference value, the adjustment direction of the step length can be determined to be the frequency reduction; if it is identified that the first temperature difference and the second temperature difference are equal to the set difference value, it may be controlled to maintain the current step size.

At this time, the operating frequency of the compressor may be further reduced according to the obtained step size and the adjustment direction of the step size.

because this application can be after opening a heat transfer unit, can at first reduce the operating frequency to predetermineeing the operating frequency, make the frequency of compressor can open quantity phase-match with heat transfer unit, and then detect through the actual temperature of adjusting well air outlet and top air outlet, reduce the operating frequency of compressor to make the indoor environment that the air conditioner was located more stable, avoid the fluctuation of indoor environment, also can avoid the energy consumption extravagant simultaneously.
