Description
Technical field
The present invention relates to air-conditioning technical field, particularly relate to air-conditioner noise control method and device.
Background technology
Operationally, the characteristic often due to each parts is different, can produce certain noise for existing air-conditioner.During object vibration, its ambient air particle is forced to move back and forth, make to produce in air alternating pressure additional on atmospheric pressure, this alternating pressure produce pressure wave be called sound wave (alternately produce compression, rarefaction state and form fluctuation), when the sound wave of frequency range 20 ~ 20000Hz pass to people's ear received by people's ear time, just become sound.The sound of various different frequency and the sound intensity combines at random, is just called noise.In a broad sense, all make people irritated, and the unwanted sound of people is all called noise.
Noise source on internal machine of air-conditioner is primarily of three kinds: 1, motor rotation noise; 2, aerodynamic noise; 3, refrigerant flowing sound.Wherein motor rotation noise, with refrigerant flowing sound, in the long-time use procedure of air-conditioner, frequency noise and loudness relatively stable; But in air-conditioner use procedure, due to evaporimeter dust stratification, structural member assembling loosens, and wind deflector swings, and rotation speed of the fan (i.e. motor speed) is different, and its noise loudness is also different.
When indoor unit of wall hanging type air conditioner runs, on the most obvious swing no more than wind deflector of aerodynamic noise impact, and the change of rotation speed of the fan.Here introduce a concept: wind deflector initial angle, that is, air-conditioner is when starting shooting, and wind deflector carries out opening action, until the rotatable maximum position of structure, more pivotal angle θ, we are called initial angle.
As shown in Figure 1: wind deflector under the drive of stepper motor, can carry out the rotation within the scope of certain angle around run-on point.In order to prevent wind deflector rotational angle excessive, often structurally the rotational angle of wind deflector is carried out to some are spacing, and this is spacing, as the original position of wind deflector initial angle, specifically, such as, set in air-conditioner main program, wind deflector is by closure state, by turning clockwise 120 ° shown in Fig. 1, but until structure maximum position wind deflector can only rotate 110 °, this difference of 10 °, exactly in order to ensure that wind deflector one turns to structure maximum position surely, and can turn round from structure maximum position; Wind deflector rotates to after the action of structure maximum position completes, then starts to be rotated counterclockwise θ angle, and stops, and now axial-flow fan rotates, and air-conditioner starts normal work, and we claim this θ to be initial angle here.
Air-conditioner is in normal work, and the rotational angle of wind deflector does not limit and rests on initial angle always, and its rotational angle regulates by remote controller; In wind deflector rotation process, its area be projected on air outlet cross section just there occurs change, that is, just there occurs change to the obstruction degree of air outlet air-flow; In general, the initial angle set in air-conditioner main program, is generally that wind deflector is turned to, hinders minimum angle to air-flow, that is, make air-conditioner when rotation speed of the fan is certain, its air output is maximum.But wind deflector is in rotation process, because the degree hindered air-flow there occurs change, the airflow value of air outlet also just changes thereupon, noise when this also can cause air-conditioner to run changes, in other words, wind deflector turns to different angles, and the level of noise of air-conditioner also can change thereupon, as shown in Figures 2 and 3:
As shown in Figures 2 and 3,1# indoor set and 2# indoor set, when initial angle θ is between 5 °-90 °, the air quantity of its correspondence and level of noise are also along with changing; The reason of its air quantity change, as said above, wind deflector hinders degree difference to cause to air outlet.
Present consumer more and more values the comfortableness that air-conditioning uses, and a wherein very important aspect is the low noise service ability of air-conditioning, especially particularly highlights when user sleeps.
When improving the noise problem that air force factor causes, a very direct way reduces the rotating speed of fan electromotor, thus the noise produced when reducing airflow circulating in air-conditioner body, in Fig. 2 and 3, the level of noise of 1# indoor set under N1 rotating speed, obviously will be greater than the level of noise under N2 rotating speed, known N1 > N2,2# indoor set also there is identical situation, and known N3 > N4;
But in a practical situation, directly infinitely variable speeds regulates the rotating speed of fan electromotor, and there is two problems: one is in speed-change process, the rotating speed of motor is gradual change, now can cause rocking of indoor set body, and the situation of body instability occurs; Two is when the rotating speed of motor is unknown, and uncertain motor is under this rotating speed, and whether the vibration frequency of itself can cause the resonance of other parts of indoor set, and particularly air-conditioner uses for a long time, and the gap length between parts changes, and resonance probability strengthens.Therefore, larger noise can be produced in current air-conditioner running, affect routine work and the life of user.
Foregoing, only for auxiliary understanding technical scheme of the present invention, does not represent and admits that foregoing is prior art.
