Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
It should be noted that description and claims of this specification and term " first " in above-mentioned attached drawing, "
Two " etc. be to be used to distinguish similar objects, without being used to describe a particular order or precedence order.It should be understood that using in this way
Data be interchangeable under appropriate circumstances, so as to the embodiment of the present invention described herein can in addition to illustrating herein or
Sequence other than those of description is implemented.In addition, term " includes " and " having " and their any deformation, it is intended that cover
Cover it is non-exclusive include, for example, the process, method, system, product or equipment for containing a series of steps or units are not necessarily limited to
Step or unit those of is clearly listed, but may include be not clearly listed or for these process, methods, product
Or other step or units that equipment is intrinsic.
According to an embodiment of the invention, as shown in Figures 1 and 2, a kind of blower control method is provided, for controlling air-conditioning system
The revolving speed of blower in system has multiple blowers in the air-conditioning system, comprising the following steps:
S10: obtaining blower rotating speed of target St, specifically, temperature sensor collects air-conditioning in air-conditioning system operational process
Supply air temperature and return air temperature, and calculate current air blow and return temperature difference threshold and be compared, before being obtained after being calculated using PID
The blower rotating speed of target St stated, the acquisition of St herein can also only collect the supply air temperature or return air temperature of air-conditioning system certainly
Degree or even the single temperature value of other setting positions are calculated after being compared as benchmark with given threshold；
Whether S20: detecting in multiple blowers has part fan to break down, in order to briefly explain the detection side of fan trouble
Method for this sentences the EC blower that current air-conditioning between arranging mostly uses, such as can carry out the inspection of fan trouble using two methods
It surveys, one is blowers a normally-closed contact, when normally-closed contact disconnects, illustrates fan trouble, namely detect normally-closed contact
State, another EC blower can feed back current rotation speed of fan, be judged as wind when controlling revolving speed and differing more with feedback revolving speed
Machine failure, that is, whether the difference between the actual speed of detection blower fan and control revolving speed is more than preset difference value；
S30: when there is part fan to break down, the initial setting for obtaining the blower not broken down in multiple blowers turns
Fast limits value S1；As S1 < 100%, the S1 for adjusting the blower not broken down is compensation making revolving speed limits value S2, S2=
S1+XS1/ (N-X), wherein N is the total number of blower, and X is the number of failure blower.
In the technical solution, when detect in air-conditioning system there are blower break down phenomenon after, it is remaining not by judgement
The relationship of the initial setting speed limits value S1 and 100% of each blower to break down, and then it is each to judge not break down
Whether a blower, which has, proposes high-revolving possibility, as S1 < 100%, namely the initial setting speed limits value of non-failure blower
S1 also not up to highest limit value (100%), illustrate at this time the limits value of rotation speed of fan there are allowance (for example, S1=80%, this
When, there is also 20% up-regulation allowances for the limits value of rotation speed of fan), it adjusts the S1 for the blower not broken down and turns for compensation making
Fast limits value S2, S2=S1+XS1/ (N-X), namely turn the reality of blower by improving the maximum speed of blower operating at this time
The raising space of speed increases, and certainly, corresponding blower rotating speed of target St also will be enhanced.In S2 >=100%, illustrate at this time
The upper limit value of rotation speed of fan up-regulation allowance is also not present, rotation speed of fan control at this time 100% namely blower at full capacity
Operating.Namely raising appropriate is carried out using revolving speed of the above method to the blower not broken down, so as to more abundant
Utilization do not break down the revolving speed surplus of blower, make full use of fan performance, can guarantee that portion occurs in blower in air-conditioning system
When dividing failure, the revolving speed loss of failure blower is made up by the way of improving non-failure rotation speed of fan, makes air-conditioning system refrigeration energy
Power is suitably corrected, and guarantees the refrigerating capacity of air-conditioning system
As S1 >=100%, raising adjustment cannot be carried out to S1 at this time, to prevent in air-conditioning system operational process, blower
Revolving speed exceeds design conditions, and the revolving speed for controlling the blower not broken down at this time is S=St+XSt/ (N-X), namely to not occurring
The revolving speed of the blower of failure carries out raising appropriate, more than the more sufficient revolving speed using the blower that do not break down
Amount, makes full use of fan performance, when can guarantee that partial fault occurs in blower in air-conditioning system, is turned using non-failure blower is improved
The mode of speed makes up the revolving speed loss of failure blower, corrects air-conditioning system refrigerating capacity suitably, guarantees air-conditioning system
Refrigerating capacity.Certainly, as S >=100%, rotation speed of fan control is 100% namely blower running at full capacity.
And it is understood that when all blower all fault-frees, all blowers are run according to S1 and St, specifically, institute
State blower using S1 and St as restrictive condition using PID adaptively adjust namely all blower normal controls operation.
Further, when detect has part fan to break down in multiple blowers, the blower control method is also wrapped
Include: the step of triggering failure fan operation, when failure blower restores to operate normally, blower is run according to S1 and St；Work as failure
When blower cannot restore to operate normally, according to the size relation of initial setting speed limits value S1 and 100%, non-failure is controlled
The revolving speed of blower, namely in air-conditioning system operational process, triggering recovery operation is carried out to the failure blower detected in real time, have
Body for example, execute the step of the triggering failure fan operation repeatedly, between adjacent triggering step twice, interval is centainly
Preset time.
Further, when detect has part fan to break down in multiple blowers, the blower control method is also
Include: manual the step of restoring failure blower, when restoring failure blower manually makes failure blower restore to operate normally, blower according to
It is run according to S1 and St；When restoring failure blower manually cannot make failure blower restore to operate normally, according to initial setting speed
The size relation of limits value S1 and 100% controls the revolving speed of the blower of non-failure.
