Abstract
The invention discloses a speed regulation control method of air conditioner outdoor fan. The method uses the temperature of conditioner outdoor coil pipe to reflect the system pressure. The RPM regulation and control strategy of the outdoor fan is designed base on the combinational factors of changes of the outdoor environmental temperature and the outdoor coil pipe temperature. Through the control of outdoor fan RPM the outdoor coil pipe temperature can be regulated. Through controlling the outdoor coil pipe temperature within the set range of temperature the system pressure can be stabilized within the scope of the reliable operation of the compressor, therefore the safe operation of the compressor can be guaranteed. Because the precise regulation of the PRM of the outdoor fan can be achieved without the unnecessary pressure sensor installation in the air conditioner system for collecting the system pressure, so the accruement of hardware cost of the product can be avoided. At the same time the stepless speed regulation is used in the outdoor fan to enhance the stability of the system pressure control, and improve the air conditioning system work performance.

In order to realize effective regulation of outdoor fan of air-conditioner rotating speed, the present embodiment is from exchange tap motor as air-conditioning system
The outdoor fan of system, and the speed control strategy that " tap speed-regulating+stepless time adjustment " combines is proposed, preferably to meet to system
The accurate control of pressure.Specifically, in the way of using tap speed-regulating, coarse regulation can be carried out to the rotating speed of outdoor fan, i.e.
Control room exogenous wind is confidential to be run with high speed Vmax, or being run with middling speed Vmid.Relay control mode can specifically be adopted
Realize two grades to outdoor fan rotating speed to adjust.As shown in Fig. 2 the work by the high speed tap J1 of outdoor fan by relay K1
Movable contact is connected to alternating current input power supplying AC_IN, low speed tap J1 and is connected to exchange input by the armature contact of relay K2
Power supply AC_IN.Using the electric-controlled plate in air-conditioner outdoor unit, control system of switching on or off electricity is carried out to the coil of two relays K1, K2, when need
When controlling outdoor fan high-speed cruising, the coil electricity of electric-controlled plate control relay K1, the coil blackout of relay K2, this
When, high speed tap J1 connects alternating current input power supplying AC_IN, so that outdoor fan is operated with high speed Vmax.For example, control outdoor fan

Continuously adjust between Vmid ~ Vmin.For example, it is possible to the scope of copped wave output is limited between 100% ~ 25%, corresponding outdoor wind
The machine range of speeds is between 370rpm/min ~ 90rpm/min.Certainly, the range of speeds can be because of the individual variation of outdoor fan
And there is deviation.
With reference to Fig. 3, the idiographic flow of the outdoor fan of air-conditioner method for controlling speed regulation of the present embodiment is carried out specifically
Bright.
（One）Start-up course：
S301, air conditioning system power-up initializing.
Whether S302, detection air-conditioning start shooting, if air-conditioning is in open state, execute subsequent step；Otherwise, keep outdoor
The stopped status of blower fan, and repeat the start detection process of this step.
S303, control outdoor fan startup, and the startup rotating speed of outdoor fan, concrete mistake is determined according to outdoor environment temperature
Cheng Wei：
Collection outdoor environment temperature Ten, and the start-up temperature point T with settingstartIt is compared, in the present embodiment, preferably sets
The fixed start-up temperature point Tstart=20℃；
If Ten>Tstart, then control outdoor fan high speed Vmax startup, for example, transported with the rotating speed high-speed starting of 730rpm/min
OK；
If 0 DEG C<Ten≤Tstart, then the startup of control outdoor fan middling speed Vmid, for example, is opened with the rotating speed middling speed of 370rpm/min
Dynamic operation；
If Ten≤ 0 DEG C, then control outdoor fan middling speed Vmid startup first, is then gradually lowered the rotating speed of outdoor fan, until
The rotating speed of outdoor fan is reduced to preset rotation speed Vset.In the present embodiment, copped wave output can be adjusted first to 100%, with control
Outdoor fan processed is started with middling speed Vmid, for example, with the rotating speed middling speed startup optimization of 370rpm/min；Then, it is gradually lowered and cuts
Ripple is exported, and for example, is exported with the rate reduction copped wave of each second 2%, and is continued 20 seconds, i.e. copped wave output is reduced to 60%, so as to
The rotating speed of outdoor fan is reduced to preset rotation speed Vset, with reducing energy consumption, reach energy-saving effect.
After control outdoor fan is according to the start operation of above start-up course, the current rotating speed of outdoor fan is kept persistently to transport
Row setting time Sset, in the present embodiment, setting time SsetIt is preferably set to 120 seconds, treats that outdoor coil temperature tends to
After stable, follow-up running is entered back into.
（Two）Running：
S304, when outdoor fan high speed Vmax start or outdoor fan switch in running high speed Vmax operation, then
During outdoor fan high-speed cruising, timing detection outdoor coil temperature TcoilerWith outdoor environment temperature Ten, when meet with
Lower two conditions 1. and 2. for the moment, the rotating speed of outdoor fan are switched to middling speed from high speed, and enter stepless time adjustment process：
1. outdoor environment temperature Ten<Tstart- △ T, and outdoor coil temperature Tcoiler≤ 35 DEG C and lasting t1 second；
2. outdoor environment temperature Ten<Tstart- △ T, and outdoor coil temperature Tcoiler≤ 25 DEG C and lasting t2 second；
In the present embodiment, the △ T is temperature increment, preferably sets △ T=3 DEG C, and preferably sets the t1=120 second, the t2=5 second.
With start-up temperature point TstartIllustrate as a example by=20 DEG C, as outdoor environment temperature Ten<17 DEG C and outdoor coil pipe used temperature
Degree Tcoiler≤ 35 DEG C and continue 120 seconds, or work as outdoor environment temperature Ten<17 DEG C and outdoor coil temperature Tcoiler≤ 25 DEG C simultaneously
When continuing 5 seconds, now, as outdoor environment temperature and outdoor coil temperature are relatively low, can meet without the need for larger heat dissipation capacity cold
Solidifying pressure/evaporating pressure>2 system requirements, therefore, it can for the rotating speed of outdoor fan to switch to middling speed, with reducing energy consumption.
Certainly, the temperature increment △ T and time t1, t2 can also be according to air-conditioning itself and its actual feelings of application scenario
Condition is set as other numerical value, and the present embodiment is not limited in above citing, but the value of t2 should be less than t1, to control outdoor fan
Rotating speed timely respond to the change of outdoor environment temperature.
S305, when outdoor fan middling speed Vmid start or outdoor fan switch in running middling speed Vmid operation
When, then enter stepless time adjustment process：
For the compressor in air conditioning system, it is to ensure its normal work, needs to control evaporating pressure and the condensation of air conditioning system
Pressure is maintained in a specific range, the pressure limit as corresponding to the as compressor safe operation of the F region in Fig. 1.In F area
In domain, the ratio of condensing pressure and evaporating pressure is all higher than 2.By carrying out a large amount of operation tests to air conditioning system, it has been found that：
Outdoor coil temperature T when air conditioning systemcoilerIn some specific temperature range [T1, T2] interior when, the system pressure of air-conditioning
Power（Condensing pressure and evaporating pressure）Fall in the F region corresponding to compressor safe operation.As long as that is, empty
Adjust the outdoor coil temperature T of devicecoilerControl is in temperature range [T1, T2], you can so that the system pressure of air-conditioner is stablized
In the interval of compressor safe operation.
Based on this, the present embodiment switches to middling speed Vmid in outdoor fan with the startup of middling speed Vmid or in running
During operation, according to outdoor coil temperature TcoilerChange, enter Mobile state adjustment to the rotating speed of outdoor fan, enter stepless time adjustment
Process, to control outdoor coil temperature TcoilerStable interior in the temperature range [T1, T2] for setting.The stepless time adjustment process is：
Work as Tcoiler<During T1, reduce the rotating speed of outdoor fan；
As T1≤TcoilerDuring≤T2, keep the rotating speed of outdoor fan constant；
Work as Tcoiler>During T2, the rotating speed of outdoor fan is raised.
Wherein, lower limit T1 described temperature range [T1, T2] value preferably between 30 DEG C to 35 DEG C, higher limit T2 is excellent
Value between 42 DEG C to 45 DEG C is selected in, concrete numerical value can carry out adaptation Sexual behavior mode according to the individual variation of air conditioning system.At this
In embodiment, temperature range [T1, the T2] is preferably set between 32 DEG C -45 DEG C, to meet most base station air conditioners
Control is required.
When dynamic regulation is carried out using AC chopping control mode to the rotating speed of outdoor fan, electrodeless entering
After speed regulation process, can be according to outdoor coil temperature TcoilerAdjustment copped wave output, changes the input voltage of outdoor fan then,
The voltage of the alternating current input power supplying AC_IN is adjusted, to realize the stepless time adjustment to outdoor fan.Specifically, Ke Yili
Outdoor coil temperature T with temperature sensor timing acquiring air-conditionercoiler,
If Tcoiler≤ 25 DEG C, only need to continue 80 seconds, you can control copped wave is exported with the rate reduction of each second 10%, with faster
The rotating speed of rate reduction outdoor fan；
If 25 DEG C<Tcoiler<T1, such as 25 DEG C<Tcoiler<32 DEG C and 100 seconds are continue for, then control copped wave was exported with each second 5%
Rate reduction, with the rotating speed of slower rate reduction outdoor fan；
If T1≤Tcoiler≤ T2, such as 32 DEG C≤Tcoiler≤ 45 DEG C and continue for 80 seconds, then it represents that the system pressure of air-conditioner
The stable interval in compressor reliability service is interior, and the copped wave output that can now remain current is constant, that is, keep outdoor fan
Current rotating speed is constant；
If T2<Tcoiler<50 DEG C, such as 45 DEG C<Tcoiler<50 DEG C and 80 seconds are continue for, then control copped wave was exported with each second 5%
Speed raise, is raised with the rotating speed that controls outdoor fan, quickening radiating rate；
If Tcoiler>=50 DEG C, only need to continue 30 seconds, you can control copped wave output is raised with the speed of each second 10%, with control room
The rotating speed of outer blower fan is quickly raised, and carries out quick heat radiating to the heat exchanger in air-conditioner outdoor unit, quickly adjusts system pressure.
During stepless time adjustment, the lower limit for defining copped wave output is D%, such as 25%.If current copped wave is output as
30%, according to above-mentioned control strategy, if desired copped wave output reduces by 10%, then execute according to the minimum copped wave output 25% for setting.Cut
The higher limit of ripple output is 100%, i.e. control outdoor fan is operated with middling speed.
When copped wave output is reduced to lower limit D%, if outdoor coil temperature Tcoiler≤ 23 DEG C and continue 60 seconds, and
Tcoiler-Ten>5 DEG C, then it represents that outdoor environment temperature and outdoor coil temperature are all relatively low, outdoor fan can be now controlled to shut down
And compressor of air conditioner remains on state（Except compressor breaks down or needs the situation of compressor shutdown because of protection）.?
In a period of the outdoor fan is shut down and compressor of air conditioner remains on state, if detecting outdoor coil temperature Tcoiler>38
DEG C and continue more than 5 seconds, then control outdoor fan starts immediately, and according to above-mentioned（One）Start-up course adjustment outdoor fan
Start rotating speed.
The above-mentioned persistent period is only for example not to limit, and can be closed according to the practical operation situation of air conditioning system
Reason is selected.
S306, outdoor fan enter stepless time adjustment process after, if meeting one of following two conditions, by outdoor fan
Rotating speed switch at a high speed：
1. the rotating speed of outdoor fan is less than or equal to the middling speed（That is, outdoor fan is run with middling speed or enters AC chopping control
Process processed）, and outdoor environment temperature Ten>Tstart+ △ T persistently t3 second, for example, Ten>23 DEG C and continue 60 seconds；Now, represent
Outdoor environment temperature is higher, is holding system pressure stability, preferably controls outdoor fan high-speed cruising, quick heat radiating；
2. outdoor fan is run with middling speed（That is, copped wave is output as 100%）, and outdoor coil temperature Tcoiler>=52 DEG C and lasting t4
Second（Such as 120 seconds）Or outdoor coil temperature Tcoiler>=55 DEG C and lasting t5 second（Such as 5 seconds）.Now, represent outdoor coil pipe used
Temperature is too high, should improve outdoor fan rotating speed, to accelerate radiating.
The above-mentioned persistent period can be set as other numerical value, but preferably define t5<t3<T4, to better control over outdoor wind
The speed of response of machine adjustment of rotational speed under different outdoor environment temperatures and outdoor coil temperature.
Using above-mentioned outdoor fan speed control strategy, the system pressure that can adjust air conditioning system stably can in compressor
By, in the interval of operation, realizing compressor and reliably and securely running.
During air conditioning system actual motion, the sensor fault for gathering outdoor coil temperature can occur unavoidably
Or for gathering the situation of the sensor fault of outdoor environment temperature.When temperature sensor is broken down, the present embodiment is excellent
Choosing adjusts the rotating speed of outdoor fan using following speed control strategy：
（1）When for gathering outdoor coil temperature TcoilerSensor fault when, the T for collectingcoilerNumerical value is unavailable, only profit
