Problems solved by technology

[0005] However, the current air-conditioning equipment with built-in fresh air function generally introduces a constant fresh air volume during fresh air operation, that is, the introduced fresh air volume is fixed, and the fresh air fan runs with the start of the air conditioner and stops with the stop of the air conditioner. , the control method is single, so in many cases, it is impossible to introduce the appropriate amount of fresh air from the outside, resulting in an increase in the load of the air-conditioning equipment and affecting the performance of the air-conditioning equipment. Especially noticeable at lower

Embodiment approach 1

[0038] In this embodiment, the air conditioner indoor unit includes a fresh air fan and a controller, and the fresh air fan is controlled by the controller. Incidentally, the fresh air fan here is equivalent to the fresh air fan mentioned in the background art, and since the present invention does not relate to the specific structure of the fresh air fan, its detailed description is omitted.

[0039] In addition, the fresh air fan has a stop gear and two operating gears including the first gear (that is, the low-speed operation gear) and the second gear (that is, the high-speed operation gear). The operating noise of the fresh air fan in the lower position increases gradually.

[0040] In addition, the air conditioner indoor unit 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 greater than the preset upper limit or lower than the preset lower limit, use...

Embodiment approach 2

[0051] This embodiment is basically the same as Embodiment 1 above, the only difference is that the indoor unit of the air conditioner also uses the detection component to detect the state of the outdoor temperature sensor, and when the detection component detects that the outdoor temperature sensor is faulty, the controller will receive Detect the fault information detected by the components, and set the fresh air fan to the low-speed operation gear.

[0052] Below, refer to figure 2 An example of the control flow of the air-conditioning indoor unit of this embodiment will be described.

[0053] In step S11, the detection component detects whether the outdoor temperature sensor works normally.

[0054] When the detection component detects that the outdoor temperature sensor is faulty in step S11, in step S12, the detected fault information is sent to the controller, and the fresh air fan is set to a low speed gear by the controller.

[0055] When the detection means detect...

Embodiment approach 3

[0060] This embodiment is basically the same as Embodiment 1 above, except that the air-conditioning indoor unit further includes a heat-exchanging fan, and the air-conditioning indoor unit uses a controller to control both the fresh air fan and the heat-exchanging fan. Incidentally, the heat exchange fan here is equivalent to the heat exchange fan mentioned in the background art, and since the present invention does not relate to the specific structure of the heat exchange fan, its detailed description is omitted.

[0061] In this embodiment, 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 noises of the heat exchange fans in the first gear to the fifth gear are sequentially Incremental, respectively 46.0dB, 47.0dB, 48.0dB, 49.0dB and 50.0dB; the fresh air fan has a stop gear and includes the first gear (that is, the low-speed operation gear) and the second gear (that is, the high-speed opera...

Abstract

Disclosed are a control method for an air conditioner indoor unit and the air conditioner indoor unit which can effectively avoid influence on performance due to improper fresh air volume. According to the control method for the air conditioner indoor unit, a controller is used for controlling a fresh air fan included by the air conditioner indoor unit. The fresh air fan has a stop gear and at least two operating gears generating different noise values. The at least two operating gears include the high-speed operating gear and the low-speed operating gear. The controller is used for receiving the outdoor temperature value obtained by an outdoor temperature sensor. When the outdoor temperature value received by the controller is larger than a preset upper limit or smaller than a preset lower limit, the controller is used for setting the fresh air fan to be at the stop gear or the low-speed operating gear or enabling the fresh air fan to operate intermittently.

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...
