Through the upper limit value that reduces compressor operating frequency, can restrict the operating frequency of compressor, avoid the operating noise of compressor to pass through the wall body and pass into indoorly, influence user and neighbour's sleep effect. Through controlling the rotating speed of the outdoor fan according to the temperature of the outdoor coil pipe, the rotating speed of the outdoor fan can be accurately adjusted, and the normal indoor heat exchange process is guaranteed while the operating rotating speed of the outdoor fan is reduced.
In this embodiment, the controlling the rotation speed of the outdoor fan according to the temperature of the outdoor coil includes: controlling the rotating speed of the outdoor fan according to the relationship between the outdoor coil temperature and the outdoor coil temperature threshold value; wherein the outdoor coil temperature threshold comprises a first outdoor coil temperature threshold and a second outdoor coil temperature threshold, and the first outdoor coil temperature threshold is greater than the second outdoor coil temperature threshold.

Through controlling the rotating speed of the outdoor fan according to the temperature of the outdoor coil pipe, the rotating speed of the outdoor fan can be accurately adjusted, and the normal indoor heat exchange process is guaranteed while the operating rotating speed of the outdoor fan is reduced.
Further, the controlling the rotation speed of the outdoor fan according to the temperature of the outdoor coil comprises: controlling the rotating speed of the outdoor fan according to the relation between the outdoor coil temperature and the outdoor coil temperature threshold value; wherein the outdoor coil temperature threshold comprises a first outdoor coil temperature threshold and a second outdoor coil temperature threshold, and the first outdoor coil temperature threshold is greater than the second outdoor coil temperature threshold.
In a specific embodiment, the temperature of the outdoor coil is divided into a plurality of intervals by setting a plurality of temperature thresholds of the outdoor coil, and the operation state of the outdoor heat exchanger can be known more accurately by judging the size relation between the temperature of the outdoor coil and the temperature threshold of the outdoor coil, so that the rotating speed of the outdoor fan can be adjusted more accurately according to the operation state of the outdoor heat exchanger.
Further, the controlling the rotating speed of the outdoor fan according to the relationship between the outdoor coil temperature and the threshold value of the outdoor coil temperature comprises: if T Outer plate ＞T 1 Increasing the rotating speed of the outdoor fan; if T 2 ≤T Outer plate ≤T 1 If so, controlling the rotating speed of the outdoor fan to be kept unchanged; if T is Outer plate ＜T 2 Reducing the rotating speed of the outdoor fan; wherein, T 1 A first outdoor coil temperature threshold; t is 2 Is a second outdoor coil temperature threshold.
For example, the air conditioner determines the magnitude relationship between the outdoor coil temperature and the outdoor coil temperature threshold value every 2 min. T is 1 Is preferably 40 ℃; t is a unit of 2 A preferred value of (b) is 32 ℃. The rotating speed of the outdoor fan is increased according to the rate of 20 revolutions per minute until the rotating speed of the outdoor fan is increased to the highest rotating speed of the outdoor fan; and the outdoor fan is reduced at the speed of 20 revolutions per minute until the rotating speed of the outdoor fan is reduced to the lowest rotating speed of the outdoor fan.

It can be understood that when the air conditioner operates in the heating mode, the frosting of the outdoor heat exchanger is easily caused by reducing the rotating speed of the outdoor fan, so that the air conditioner is only effective in the cooling operation mode or the dehumidifying operation mode. When the air conditioner operates in a refrigeration mode, the outdoor air speed is reduced to cause the condensation pressure of the air conditioner to rise, and the problem of shutdown protection caused by overhigh system pressure can be avoided by setting the limiting condition that the outdoor environment temperature is less than the outdoor environment temperature threshold value when the outdoor environment temperature is more than or equal to the outdoor environment temperature threshold value, namely under the condition that the outdoor environment temperature is higher. Because the reduction of indoor and outdoor wind speed can lead to the reduction of refrigerating capacity, the indoor temperature needs to be reduced to a comfortable temperature first, then the mode of reducing the rotating speed and muting the rotating speed is allowed to enter, namely, the refrigerating effect is prior.
Further, the second preset condition includes: the indoor environment temperature is less than or equal to an indoor environment temperature threshold value; or the difference between the indoor environment temperature and the set temperature is less than or equal to the difference threshold.

Further, if the second operation parameter does not meet the first preset condition, the air conditioner is controlled to operate according to a conventional mode, the operation of obtaining the indoor light brightness is not executed, and the operation of judging the size relation between the indoor light brightness and the indoor light brightness threshold value is carried out.
In one embodiment, if the second operating parameter does not satisfy the first preset condition, it indicates that the air conditioner currently has the problem of excessive noise reduction, so that the air conditioner is controlled to exit the mute function of the internal and external units, so as to ensure the normal indoor heat exchange process.
