Description
Technical field
The present invention relates to a kind of motor control methods of multi fan air conditioner indoor unit.
Background technology
Due to single wind turbine air conditioner indoor unit, there are noise is big, high energy consumption, cannot to meet comfort level etc. a series of at runtime
, there is multi fan air conditioner indoor unit at present in problem, and fan part includes at least two motors and is separately mounted to motor
Fan blade on axis, a motor and a fan blade are one group, and every group of motor and fan blade are blown using independent air duct, are adopted
With the air conditioner indoor unit of above-mentioned fan part, the effect that more low-power machines are run simultaneously fully achieves high-power
The operational effect of single motor, multi fan air conditioner indoor unit are compared with single wind turbine air conditioner indoor unit, are equivalent to multiple independent ventiducts point
Heat exchange is not carried out with heat exchanger, increases heat exchange area and heat exchange efficiency, and motor speed can during equal refrigerating capacity output
With very low, theoretically noise smaller, however, being found in multi fan air conditioner indoor unit operational process in practice, in order to make along outlet air
Mouth direction thermo parameters method evenly, improves air supplying distance, and multi fan motor need to be run with same rotating speed, but when multi fan
When motor is run with same rotating speed, larger resonance can be generated, increases noise instead, user experience is very poor, if making multi fan
Motor when being run with constant differential, and can not ensure the even results along air outlet direction thermo parameters method.
Invention content
The technical problems to be solved by the invention are the shortcomings that overcoming the more than prior art：There is provided one kind can ensure
Air port direction uniform distribution of temperature field, but it is possible to prevente effectively from the motor resonant belt of multi fan carrys out the windy air conditioner of loud noise
The motor control method of indoor unit.
The technical solution of the present invention is as follows：A kind of motor control method of multi fan air conditioner indoor unit, it is described windy
The fan part of air conditioner indoor unit includes N number of motor, and N >=2, it includes the following steps：
1）After multi fan air conditioner indoor unit receives power-on instruction, electricity is opened according to needed for calculating the target air volume of setting
The rotating speed of target R of machine number M and motor；
2）If required unlatching motor number M is 1, the required actual speed for opening motor is set as rotating speed of target R；If institute
Motor number M need to be opened more than or equal to 2, then randomly generate the M integers being not mutually equal, and integer difference is not mutually equal by this M
After being added with rotating speed of target R unlatching motor needed for M is respectively allocated to as actual speed；
3）Motor is opened needed for M with step 2）The actual speed operation being assigned to.
Step 2）In, the M integers being not mutually equal are randomly selected from integer range [- 5 ,+5].
The M integers being not mutually equal are by calling random number generation function to obtain.
The N is 2 or 3.
The beneficial effects of the invention are as follows：Since the rotating speed of each wind turbine is sufficiently close to rotating speed of target R, and randomly generate, because
This is averaged air output very close to so as to along air outlet direction uniform distribution of temperature field, and because each wind turbine along air channel
Rotating speed is different, avoids resonance noise, substantially increases the comfort to human body, the present invention can ensure air outlet direction temperature
Field distribution is uniform, and it is possible to prevente effectively from the motor resonant belt of multi fan carrys out loud noise.
Description of the drawings
Fig. 1 is the flow chart of the motor control method of multi fan air conditioner indoor unit of the present invention.
Specific embodiment
The present invention is described in further details with specific embodiment below, but the present invention is not only limited in detail below in fact
Apply example.
Embodiment one
As shown in Figure 1, a kind of motor control method of multi fan air conditioner indoor unit, the wind of the multi fan air conditioner indoor unit
Machine component includes N number of motor, and N >=2, it includes the following steps：
1）After multi fan air conditioner indoor unit receives power-on instruction, electricity is opened according to needed for calculating the target air volume of setting
The rotating speed of target R of machine number M and motor；
2）If required unlatching motor number M is 1, the required actual speed for opening motor is set as rotating speed of target R；If institute
Motor number M need to be opened more than or equal to 2, then randomly generate the M integers being not mutually equal, and integer difference is not mutually equal by this M
After being added with rotating speed of target R unlatching motor needed for M is respectively allocated to as actual speed；
3）Motor is opened needed for M with step 2）The actual speed being assigned to runs and enters closed-loop control.
Step 2）In, the M integers being not mutually equal are randomly selected from integer range [- 5 ,+5].
The M integers being not mutually equal are by calling existing random number generation function to obtain.
The N is 2 or 3.
Embodiment two
Below to be further illustrated for including the air conditioning indoor machine motor control method of 2 wind turbines, it includes following step
Suddenly：
1）After air conditioner indoor unit receives power-on instruction, motor is opened according to needed for calculating the target air volume of remote control setting
The rotating speed of target R of number M and motor；
2）If required unlatching motor number M is 1, the required actual speed for opening motor is set as rotating speed of target R；If institute
It is 2 that motor number M, which need to be opened, then randomly generates 2 from integer range [1,12] by calling existing random number generation function
The integer being not mutually equal, and this 2 are not mutually equal after integer is added respectively with rotating speed of target R and is distributed respectively as actual speed
To unlatching motor needed for M；Such as two motors are respectively the first motor, the second motor, two random integers of acquisition are distinguished
It is 2,5；Then the actual speed of the first motor is set as（R+2）, the actual speed of the second motor is set as（R+5）.
3）Motor is opened needed for 2 with step 2）The actual speed being assigned to runs and enters closed-loop control.
It is averaged outlet air since the rotating speed of each wind turbine is sufficiently close to rotating speed of target R, and randomly generate, therefore along air channel
Amount is very close to so as to along air outlet direction uniform distribution of temperature field, and because each rotation speed of fan is different, avoiding resonance and make an uproar
Sound substantially increases the comfort to human body.
It the above is only the feature implementation example of the present invention, the scope of the present invention be not limited in any way.It is all to use together
The technical solution formed Deng exchange or equivalence replacement, all falls within rights protection scope of the present invention.
