Embodiment approach 1

[0037] In this embodiment, the air conditioner indoor unit includes a heat exchanging fan, a fresh air fan and a controller, and the heat exchanging fan and the fresh air fan are controlled by the controller. Incidentally, the heat exchange fan and the fresh air fan here are respectively equivalent to the heat exchange fan and the fresh air fan mentioned in the background art. Since the present invention does not relate to the specific structures of the heat exchange fan and the fresh air fan, the detailed description thereof is omitted.

[0038] In addition, the heat exchange fan has a stop gear and a plurality of operating gears including the first gear to the fifth gear, and the operating noise of the heat exchange fans in the first gear to the fifth gear increases sequentially, respectively 46.0dB, 47.0dB, 48.0dB, 49.0dB and 50.0dB; the fresh air fan has a stop gear and two running gears including the first gear and the second gear, the first gear and the second gear The o...

Embodiment approach 2

[0048] In this embodiment, the air conditioner indoor unit includes a heat exchanging fan, a fresh air fan and a controller, and the heat exchanging fan and the fresh air fan are controlled by the controller. Like Embodiment 1, the heat exchange fan and the fresh air fan here are respectively equivalent to the heat exchange fan and the fresh air fan mentioned in the background technology. Since the present invention does not involve the specific structures of the heat exchange fan and the fresh air fan, details thereof are omitted. illustrate.

[0049] In addition, the heat exchange fan has a stop gear and two operating gears including a high-speed operating gear and a low-speed operating gear. The operating noise of the heat-exchanging fan in the high-speed operating gear and the low-speed operating gear increases gradually, respectively 36dB and 40dB; the fresh air fan has a stop gear and two running gears including a high-speed running gear and a low-speed running gear. 35...

Embodiment approach 3

[0065] This embodiment is basically the same as the above Embodiment 2, the only difference is that the air conditioner indoor unit also uses the controller to receive the outdoor temperature value obtained by the outdoor temperature sensor, and, when the controller receives the outdoor temperature value When the temperature value is greater than the preset upper limit or lower than the preset lower limit, use the controller to set the fresh air fan to the stop gear or low-speed operation gear, or make the fresh air fan perform intermittent operation (that is, set a running Time and interval time, during the operation time, the fresh air fan is running, after the running time, the fresh air fan is stopped, and after the interval time is satisfied, the fresh air fan starts to run again).

[0066] According to this embodiment, the same technical effect as that of Embodiment 2 above can be achieved.

[0067] In addition, according to this embodiment, it is possible to avoid affec...

Abstract

The invention discloses a control method of an air conditioner indoor unit and the air conditioner indoor unit. The noise of a fresh air fan can be effectively restrained. The control method of the air conditioner indoor unit is characterized in that a controller is used for controlling a heat exchange fan and the fresh air fan which are included in the air conditioner indoor unit, the heat exchange fan has a stop gear and at least two operating gears generating different noise values, and the fresh air fan has a stop gear and at least two operating gears generating different noise values; when the heat exchange fan operates at any operating gear, the controller is used for limiting the highest operating gear of the fresh air fan, and therefore the difference value of the total noise value obtained after superposition of noises generated by operating of the heat exchange fan and the fresh air fan and the noise value of the heat exchange fan is smaller than the preset value.

Description

technical field [0001] The invention relates to a control method of an air conditioner indoor unit and the air conditioner indoor unit, in particular to a control method of an air conditioner indoor unit with a fresh air function and an air conditioner indoor unit with a fresh air function controlled by the control method. Background technique [0002] With the improvement of living standards, people's requirements for the living environment are getting higher and higher, and they pay more and more attention to health and comfort. The definition of the living environment is no longer limited to a spacious living space. The time spent indoors is much longer than outdoors, and the quality of indoor air is directly related to people's health, so indoor air quality has become one of the evaluation factors of living environment. [0003] To improve indoor air quality, the most effective way is to increase the indoor fresh air volume, which can generally be achieved by opening win...
