According to the air conditioner mute control method, if the current actual noise value is smaller than the set noise value, the rotating speeds of the indoor fan and the compressor can be properly increased, so that the problem of poor refrigerating and heating effects is solved; if the current actual noise value is larger than the set noise value, the rotating speed of the indoor fan and the rotating speed of the compressor need to be properly reduced so as to solve the problem of high current noise.
In this embodiment, the speed of decreasing/increasing the rotation speed of the compressor is determined according to the difference △ R between the actual noise value R and the set noise value R, so as to not only improve the cooling and heating effects as soon as possible, but also avoid the excessive increase of the actual noise value caused by the excessive decrease/increase of the rotation speed of the compressor.
Specifically, the method comprises the following steps:
(1) when △ r is less than or equal to the first set difference, the speed of compressor is decreased/increased by the first set value every second.
(2) When the first set difference is less than △ r and less than the second set difference, the compressor speed is decreased/increased by the second set value every second.
(3) When the second set difference is less than △ r and less than the third set difference, the compressor speed is decreased/increased by the third set value per second.

The difference △ r is different, and the reduction/increase value of the compressor rotating speed per second is different, so that the accurate control of the compressor rotating speed is realized, the refrigeration and heating effects are improved as soon as possible, and the actual noise value is prevented from increasing too fast due to too fast change of the compressor rotating speed.
In this embodiment, the first set difference is 10dB, the second set difference is 20dB, the third set difference is 30dB, and the fourth set difference is 40 dB; the first set point is 1rps, the second set point is 2rps, the third set point is 3rps, the fourth set point is 4rps, and the fifth set point is 5 rps.
In this embodiment, the speed of decreasing/increasing the rotation speed of the indoor fan is determined according to the difference △ R between the actual noise value R and the set noise value R, so as to improve the cooling and heating effects as soon as possible, and avoid the actual noise value increasing too fast due to too fast decreasing/increasing of the rotation speed of the indoor fan.
Specifically, the method comprises the following steps:
(1) and when the △ r is smaller than or equal to the first set difference value, the rotating speed of the indoor fan is reduced/increased by a sixth set value every second.
(2) And when the first set difference is less than △ r and less than or equal to the second set difference, the rotating speed of the indoor fan is reduced/increased by a seventh set value every second.
(3) And when the second set difference is less than △ r and less than or equal to the third set difference, the rotating speed of the indoor fan is reduced/increased by an eighth set value every second.
(4) And when the third set difference is less than △ r and less than the fourth set difference, the rotating speed of the indoor fan is reduced/increased by a ninth set value every second.
(5) When the fourth setting difference is < △ r, the indoor fan speed is lowered/raised by the tenth setting value every second.
Wherein the sixth set value is larger than the seventh set value, the eighth set value is larger than the ninth set value, and the tenth set value.
The difference △ r is different, and the value of the indoor fan rotating speed reducing/increasing per second is different, so that the accurate control of the indoor fan rotating speed is realized, the refrigerating and heating effects are improved as soon as possible, and the actual noise value is prevented from increasing too fast due to too fast change of the indoor fan rotating speed.
In this embodiment, the first set difference is 10dB, the second set difference is 20dB, the third set difference is 30dB, and the fourth set difference is 40 dB; the sixth set point is 5rps, the seventh set point is 10rps, the eighth set point is 15rps, the ninth set point is 20rps, and the tenth set point is 25 rps.
The noise set value can be set through the air conditioner remote controller according to actual demand, and is nimble convenient, satisfies user differentiation demand.
The noise setting value can be set according to the requirements of users, if the air conditioner noise is expected to be as small as possible, the corresponding noise setting value is set to be smaller, otherwise, the air conditioner noise can be higher. It is not to be said that the larger the noise set value is, the higher the air conditioning noise is because the rotational speed of the indoor fan and the rotational speed of the compressor of the air conditioner are related to the set temperature and the current ambient temperature in addition to being affected by the set noise value. If the set temperature is reached, the rotating speed of the fan of the indoor unit and the rotating speed of the compressor can not be increased even if the set noise value is large.
In the embodiment, the noise set value is 20 dB-70 dB, and the compressor and the indoor fan are controlled to keep proper rotating speed, so that lower noise is ensured, and better refrigerating and heating effects are ensured.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
