Problems solved by technology

Although the shielding strategy can solve the noise generated by the compressor, when the shielding section of the compressor is just connected with the shielding section with excessive piping vibration or stress, the shielding section will be too long, making the operating frequency of the compressor discontinuous and affecting the precise temperature. control, it will affect the frequency use of free frequency

no. 1 example

[0030] Please refer to figure 1 , figure 1 A flow chart of steps of a method for controlling an external air conditioner provided by an embodiment of the present invention is shown. The above method for controlling an external unit of an air conditioner is applied to an air conditioner. The above-mentioned air conditioner includes a compressor and a fan. like figure 1 As shown, the steps of the method for controlling the outdoor unit of the air conditioner include:

[0031] Step S101, obtaining the stable frequency of the compressor and the current rotational speed of the fan.

[0032] In the embodiment of the present invention, the manner of obtaining the stable frequency of the compressor and the current rotational speed of the fan may be: collecting the current frequency of the compressor at preset time intervals. It is judged according to the collected current frequency whether the compressor enters a stable running state. Optionally, the judging manner may be judgin...

[0056] An embodiment of the present invention provides a method for controlling an external unit of an air conditioner. The above method for controlling an external unit of an air conditioner is applied to an air conditioner. The method for controlling the external unit of the air conditioner provided in this embodiment is substantially the same as the method for controlling the external unit of the air conditioner provided in the first embodiment, and will not be repeated here. The difference between the two is that, in the embodiment of the present invention, whether to adjust the conversion by adding an adjustment parameter to the original rotation speed or to adjust the rotation speed by reducing the adjustment parameter based on the original rotation speed can be based on the current indoor temperature. Specifically, such as image 3 As shown, the above-mentioned adjustment of the speed of the fan according to the preset adjustment parameters may include the following su...

[0063] An embodiment of the present invention provides a method for controlling an external unit of an air conditioner. The above method for controlling an external unit of an air conditioner is applied to an air conditioner. The method for controlling the external unit of the air conditioner provided in this embodiment is substantially the same as the method for controlling the external unit of the air conditioner provided in the first embodiment, and will not be repeated here. The difference between the two is that in the embodiment of the present invention, whether to adjust the conversion by adding an adjustment parameter on the basis of the original rotation speed or to adjust the rotation speed by reducing the adjustment parameter on the basis of the original rotation speed can be based on the current indoor temperature and Outdoor temperature. Specifically, such as Figure 4 As shown, the above-mentioned adjustment of the speed of the fan according to the preset adjus...

Abstract

The invention provides an air conditioner external unit control method and device, wherein the air conditioner external unit control method is applied to an air conditioner. The air conditioner storesa resonance frequency range corresponding to each rotation speed, and the air conditioner includes a fan and a compressor. The control method comprises the steps that a stable frequency of the compressor and a current rotational speed of the fan are acquired, and whether an anti-resonance mode is started or not is determined based on the obtained stable frequency and the resonant frequency rangecorresponding to the current rotational speed. If the anti-resonance mode is started, the rotation speed of the fan is adjusted according to preset adjustment parameters until a preset condition for exiting the anti-resonance mode is satisfied. According to the scheme, the noise reduction is realized by preventing the compressor and the fan from generating solid-frequency vibration. At the same time, the effect of directly switching the wind gear on the running effect of a complete machine is avoided.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to a control method and device for an air conditioner external unit. Background technique [0002] With the advancement of modernization, air conditioners have gradually become a must-have electrical appliance for families. There is no doubt that air conditioners play a role in promoting the improvement of people's living environment, but even today when air conditioning technology is so mature, there are still many problems with air conditioners. Among them, the noise problem is the most concerned issue for users and air conditioner research and development. [0003] In recent years, air conditioner research and development has been devoted to continuously improving the noise of air conditioners. Taking the noise generated by compressors as an example, the current mainstream method of dealing with air conditioner noise is to use shielding strategies. Although the shieldin...
