The invention discloses a kind of noise control methods of the blower of air-conditioner outdoor unit, the specific steps of which are as follows: the quantity of the master controller detection blower fan of a, air-conditioning, and judge whether it is DC fan, if blower quantity is more than 1, and be DC fan, then enter in next step；B, dividing from the maximum speed Amax of each blower to minimum speed Amin is N grades, and the revolving speed of every level-one differs (Amax-Amin)/N；C, sequence number is assigned to each blower according to the physical location of each assembling；D, when motor operation, all sequences number are that the rotation speed of fan of odd number is identical, and all sequences number are that the rotation speed of fan of even number is also identical, and the series gap between odd number blower and even number blower is 1 grade；When the series of any one blower is equal to 0, fan parking.This method is in the blower using unified blade and do not reduce heat exchange under the premise of can effective noise reduction.
Description
Technical field
The present invention relates to the control methods of air conditioner, are especially a kind of noise control side of the blower of air-conditioner outdoor unit
Method, more specifically, being that there are noise control methods when 2 or more DC fans for air-conditioner outdoor unit.
Background technique
For air-conditioning device, outdoor unit heat exchange needs outdoor fan to run, and forms forced-convection heat transfer, passes through air
Guarantee the refrigeration or heating of system with coil heat exchange.Since there are forced convertions, noise can be generated, especially the outdoor unit is deposited
In multiple blowers and when above-mentioned multiple blowers are again DC fan, since DC fan itself is that have grade adjusting side with gear
Formula, and the another cause of gear and frequency when each fan operation, therefore influence each other between blower, resonance, cause noise into
One step increases, and as air quantity increases, and noise is naturally bigger, seriously affects user experience.
For control noise, two methods are mainly used in industry, first is that the blower of different leaves quantity is selected, second is that with
Reducing revolution, sacrificing air quantity is cost to reduce noise.There is drawback in the above method, the former needs to develop a kind of new leaf
Piece, the poor universality of blower components；The latter causes heat exchange amount and heat exchange efficiency to reduce, and has influenced the refrigerated medium thermal effect of air-conditioning
Fruit.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of before using the blower of unified blade and not reducing heat exchange
Put can effectively noise reduction air-conditioner outdoor unit blower noise control method.
The technical solution of the invention is as follows, provides a kind of noise control method of the blower of air-conditioner outdoor unit, specific
Steps are as follows:
A, the quantity of the master controller detection blower fan of air-conditioning, and judge whether it is DC fan, if blower quantity is more than 1
Platform, and be DC fan, then enter in next step；
B, dividing from the maximum speed Amax of each blower to minimum speed Amin is N grades, and the revolving speed of every level-one differs
(Amax—Amin)/N；
C, sequence number is assigned to each blower according to the physical location of each assembling；
D, when motor operation, all sequences number are that the rotation speed of fan of odd number is identical, and all sequences number are that the blower of even number turns
Speed is also identical, and the series gap between odd number blower and even number blower is 1 grade；When the series of any one blower is equal to 0
When, fan parking.
Using above method, the noise control method of the blower of air-conditioner outdoor unit of the present invention compared with prior art, has
Following advantages:
Since the gear between each blower and adjacent blower of above-mentioned outdoor unit is staggered, therefore avoid production when fan operation
Raw frequency superposition, it is ensured that in the blower using unified specification blade and while do not reduce air quantity, noise is preferably minimized, from
And the comfort of air-conditioner set is improved, optimize user experience.
Specific embodiment
The noise control method of the blower of air-conditioner outdoor unit of the present invention, specific step is as follows.
A, the master controller of air-conditioning detects the quantity of the blower of the air-conditioner outdoor unit, and judges whether it is DC fan, such as
Fruit blower quantity is more than 1, and is DC fan, then enters in next step.
B, dividing from the maximum speed Amax of each blower to minimum speed Amin is N grades, and the revolving speed of every level-one differs
(Amax—Amin)/N；For example, the maximum speed Amax of blower is generally 1000-1500rps, such as 1000rps, and it is minimum
Revolving speed Amin is generally 0-200rps, such as 100rps, is divided into 9 grades, then the revolving speed of every level-one differs 100rps.
C, sequence number is assigned to each blower according to the physical location of each assembling；If any four Fans, then mark
For blower 1, blower 2, blower 3, blower 4.
D, when motor operation, all sequences number are that the rotation speed of fan of odd number is identical, and all sequences number are that the blower of even number turns
Speed is also identical, and the series gap between odd number blower and even number blower is 1 grade；Such as the outdoor unit has 4 Fans altogether, then wind
Machine 1 is run with M grades, and blower 2 is run with 1 grade of M-, and blower 3 is run with M grades, and blower 4 is run with 1 grade of M-.
When the series of any one blower is equal to 0, fan parking.
It is emphasized that revolving speed problem, in the prior art, the master controller of air-conditioning can be according to the load and target of unit
Temperature conversion goes out a rotating speed of target.And the present embodiment is classified by the revolving speed of step b blower, so that the odd number in step d
Revolving speed A2 corresponding to the series of revolving speed A1 corresponding to the series of blower and even number blower, the average value of two revolving speeds, etc.
In the rotating speed of target of unit, air quantity and heat exchange amount are guaranteed with this.
For example, the maximum speed of unit is 1000 if the rotating speed of target of each blower of unit needs is 550rps
And minimum speed is 100 and to be divided into 9 grades, then odd number blower with 6 grades of operatings and even number blower is operated with 5 grades, it is average to turn
Speed remains as 550rps.Just in case rotating speed of target is not achieved in mean speed, the rotating speed of target as this unit needs is 500rps, then
Still odd number blower with 6 grades of operatings and even number blower is operated with 5 grades, although last rotating ratio rotating speed of target is slightly larger, protect
Air quantity has been demonstrate,proved, and since adjacent rotation speed of fan is staggered, has still effectively reduced noise.
