Description
Technical field
The present invention relates to air-conditioning technical field, more particularly to air conditioner noise adjusting method and device.
Background technology
Existing air conditioner operationally, often due to the characteristic of each parts is different, can produce certain noise.Object vibration
When, force the air particle around it to move back and forth, make to produce the alternating pressure added on atmospheric pressure, this friendship in air
Pressure wave caused by pressure changeable be referred to as sound wave (be alternately produced compression, rarefaction state and form fluctuation), when frequency range 20~
When 20000Hz sound wave passes to human ear and received by human ear, just turn into sound.The sound of various different frequencies and the sound intensity is at random
Combination, is known as noise.In a broad sense, all make one irritated, and the unwanted sound of people is referred to as noise.
Noise source on internal machine of air-conditioner mainly has three kinds：1st, motor running noise；2nd, aerodynamic noise；3rd, refrigerant
Flowing sound.Wherein motor running noise, with refrigerant flowing sound, during air conditioner long-time use, frequency noise and its sound
Degree is relatively stable；But during air conditioner use, due to evaporator dust stratification, structural member assembling is loosened, and wind deflector is swung, fan
Rotating speed (i.e. motor speed) is different, and its noise loudness is also different.
When indoor unit of wall hanging type air conditioner is run, aerodynamic noise is influenceed the most significantly no more than wind deflector
Swing, and the change of rotation speed of the fan.Here a concept is introduced：Wind deflector initial angle, i.e. air conditioner is in start, wind-guiding
Plate carries out opening action, until the rotatable maximum position of structure, then the angle, θ turned round, we are referred to as initial angle.
As shown in Figure 1：Wind deflector around run-on point can in the range of certain angle turn under the drive of stepper motor
It is dynamic.In order to prevent wind deflector rotational angle excessive, often carry out that some are spacing to the rotational angle of wind deflector in structure, and will
This is spacing, as the original position of wind deflector initial angle, specifically, for example, being set in air conditioner main program, wind deflector
By closure state, turn clockwise as shown in Figure 1 120 °, but until structure maximum position wind deflector can only rotate 110 °, this 10 °
Difference, exactly in order to ensure that wind deflector one surely turns to structure maximum position, and can be since structure maximum position
Revolution；Wind deflector, which is rotated to the action of structure maximum position, to be completed and then starts rotate counterclockwise θ angles, and is stopped, and is now passed through
Flow fan rotates, and air conditioner starts normal work, and this θ is referred to as initial angle here.
Air conditioner is in normal work, and the rotational angle of wind deflector does not limit rests on initial angle always, its angle of rotation
Degree can be adjusted by remote control；In wind deflector rotation process, its area being projected on air outlet section is just changed,
That is, the obstruction degree of air outlet air-flow is just changed；In general, set in air conditioner main program initial
Angle, wind deflector usually is turned to, hinder air-flow minimum angle, i.e. so that air conditioner is in rotation speed of the fan certain
In the case of, its air output is maximum.But wind deflector, due to changing to the degree that air-flow hinders, goes out in rotation process
The airflow value in air port also just changes therewith, and noise when this also results in air conditioner operation changes, in other words, wind deflector
Different angles is turned to, the level of noise of air conditioner is also to change therewith, as shown in Fig. 2 and 3：
As shown in Figures 2 and 3,1# indoor sets and 2# indoor sets, when initial angle θ is between 5 ° -90 °, its corresponding wind
Amount and level of noise are also with change；The reason for its air quantity changes, it is described as discussed above, it is that wind deflector hinders journey to air outlet
Caused by degree is different.
Present consumer increasingly values the comfortableness that air-conditioning uses, wherein critically important is air-conditioning on one side
Low noise service ability, especially particularly highlighted in the case where user sleeps.
When improving noise problem caused by air force factor, a very direct method is to reduce fan electromotor
Rotating speed, so as to reduce noise caused by the circulation of air conditioner body interior air-flow, as in Fig. 2 and 3,1# indoor sets are in N1 rotating speeds
Under level of noise, the level of noise that be significantly greater than under N2 rotating speeds, it is known that N1 ＞ N2, also there is identical situation on 2# indoor sets,
And known N3 ＞ N4；
But in a practical situation, directly variable speed adjusts the rotating speed of fan electromotor, there are problems that two：When
In speed-change process, the rotating speed of motor is gradual change, can now cause rocking for indoor set body, and the unstable feelings of body occur
Condition；Second, when the rotating speed of motor is unknown, and uncertain motor, under this rotating speed, whether the vibration frequency of itself can cause interior
The resonance of other parts of machine, particularly air conditioner use for a long time, and the gap length between parts changes, and resonance is several
Rate increases.Therefore, larger noise can be produced in current air conditioner running, influences the routine work and life of user.
The above is only used for auxiliary and understands technical scheme, does not represent and recognizes that the above is existing skill
