Embodiment approach 1

[0037] In this embodiment, the air conditioner indoor unit includes a heat exchange fan, a fresh air fan, and a controller, and the heat exchange fan and the fresh air fan are controlled by the controller. By the way, 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 involve the specific structure of the heat exchange fan and the fresh air fan, detailed descriptions thereof are omitted.

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

Embodiment approach 2

[0048] In this embodiment, the air conditioner indoor unit includes a heat exchange fan, a fresh air fan, and a controller, and the heat exchange fan and the fresh air fan are controlled by the controller. As in 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 art. Since the present invention does not involve the specific structure of the heat exchange fan and the fresh air fan, the details are omitted. Description.

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

Embodiment approach 3

[0065] This embodiment is basically the same as the above-mentioned embodiment 2, except 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 outdoor temperature value received by the controller is When the temperature value is greater than the preset upper limit or less than the preset lower limit, the controller is used to set the fresh air fan to the stop gear or low-speed operation gear, or to make the fresh air fan run intermittently (that is, set a run Time and interval time, during the operation time, the fresh air fan runs, after the operation time has elapsed, the fresh air fan stops, and when the interval time is met, the fresh air fan starts to operate).

[0066] According to this embodiment, the same technical effect as the above-mentioned second embodiment can be achieved.

[0067] In addition, according to this embodiment, it is possible to prevent the performanc...

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 present invention relates to a control method of an air conditioner indoor unit and an air conditioner indoor unit, in particular to a control method of an air conditioner indoor unit with fresh air function and an air conditioner indoor unit with 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 more and more attention is paid to health and comfort. The definition of living environment is no longer limited to spacious living spaces. For example, because people are in The indoor time is much longer than the outdoor time. The quality of indoor air is directly related to human health. Therefore, indoor air quality has become one of the evaluation factors of the living environment. [0003] To improve indoor air quality, the most effective way is to increase the amount of indoor fresh air, which can ge...
