Fig. 1 is a kind of flow chart of air-conditioning electric heating controlling method according to an exemplary embodiment.Such as Fig. 1 institutes
Show, as shown in figure 1, the process of air-conditioning electric heating control includes：
Step 101：Obtain current humidity value corresponding with current period in the air-conditioning zone of action.
, can be by controlling electrically heated switch time in the setting cycle, so as to control electrical heating in the embodiment of the present invention
Power output.Therefore, the cycle can be preset, such as：A cycle 5 minutes, 8 minutes, 10 minutes, 12 minutes etc..Week
Phase length refers to the processing speed of the processor of air-conditioning, and firing rate, power etc. the parameter of electrical heating hardware is come really
It is fixed.
After the default cycle is determined, for each cycle, the control that can be all electrically heated.Here, air-conditioning is obtained
Current humidity value corresponding with current period in the zone of action.Current temperature value can be obtained by humidity sensor, can also led to
Acquisition current temperature value is crossed, current temperature value is obtained after carrying out computing.For example, according to current temperature value, interior machine coil temperature value,
Compressor operating frequency value, and opening value, the current humidity value in current temperature and humidity value is obtained by following formula.
Rhn=A2*Tn1+B2*Tn2+C2*hzn+D*fn+F
Wherein, RhnFor current humidity value, Tn1 is current temperature value, Tn2 be interior machine coil temperature value, hznTransported for compressor
Line frequency value, fnFor opening value, AA2、B2、C2, D, E, F be respectively according to the type of air-conditioning determine constant, n is current period
Order.
Such as：Current period is the 50th cycle, then can obtain current humidity value Rh according to above-mentioned formulan=35%.
Step 102：According to current humidity value, and the target humidity value of setting, current humidity deviation is determined.
Can direct goal-selling humidity value, such as：Rht=45%.Or after user sets preset temperature value, according to

The comfort humidity value of determination is defined as to the target humidity value of setting.
Obtain current humidity value, and after the target humidity value of setting, can be directly by by current humidity value and setting
Difference between target humidity value, it is defined as current humidity deviation.
Because electrical heating divides the cycle to be controlled, therefore, further to improve the accuracy of control, contingency is reduced
The probability of error, in another embodiment of the present invention, determining the process of current humidity deviation may include：By current humidity value and work as
Humidity value corresponding to the top n continuous cycle in preceding cycle is weighted average calculating operation, obtains current presumption humidity value, and ought
Difference between preceding presumption humidity value and the target humidity value of setting, is defined as current humidity deviation.
Such as：N=5, so, can be according to Rhn, Rhn-1, Rhn-2, Rhn-3, Rhn-4, Rhn-5This six data, are averaged
Computing, current presumption humidity value Rhp is obtained, so as to current humidity deviation delta RH=Rhp-Rht。
Step 103：According to current humidity deviation, and the humidity deviation in a upper cycle, ratio, integration, differential were carried out
(PID) control, determine opening time of the air-conditioning electrical heating in current period.
Current humidity deviation is had determined, also, humidity deviation value corresponding to each cycle can be preserved, from
And it also would know that the humidity deviation in a cycle.Or humidity value and the mesh of setting according to corresponding to each cycle of preservation
Humidity value is marked, can also obtain the humidity deviation of a cycle.
So that the changing value of humidity deviation according to current humidity deviation, and the humidity deviation in a upper cycle, can be obtained,
That is the changing value DRH=Δ RH- Δs RH of humidity deviation1, wherein, Δ RH1For the humidity deviation in a upper cycle.
Then, according to formula (1), and formula (2), opening time ratio of the air-conditioning electrical heating in current period is determined
Example；Wherein,
Δ Heater_p=Int ((Heater_Ki×ΔRH+DRH×Heater_Kp) × 100)/100---- formula (1)
Heater_p=Δs Heater_p+Heater_p1--------------------------------------
Formula (2)
Δ RH is current humidity deviation, and DRH is the changing value of humidity deviation, Heater_Ki,
Heater_KpFor revisable ratio, integration, differential (proportion, integral, derivative, PID)
Calculating parameter, Δ Heater_p are the electrically heated opening time proportional difference of air-conditioning, and Heater_p is air-conditioning electrical heating current
Opening time ratio in cycle, Heater_p1For opening time ratio of the air-conditioning electrical heating within a upper cycle.
Equally, air-conditioning can preserve the opening time ratio in each cycle.Such as：Air conditioner electric can determine that by formula (1)
The opening time proportional difference Δ Heater_p=5% of heating, and the opening time ratio Heater_p in a upper cycle1=
30%, so as to which opening time ratio Heater_p=35% of the air-conditioning electrical heating in current period can be obtained.
Finally, it can determine air-conditioning electrical heating in current period according to cycle and opening time ratio Heater_p
Opening time.Such as：If the cycle set is 8 minutes, and 1% is i.e. corresponding 4.8 seconds, so as to, it may be determined that in current period, electricity adds
The opening time of heat is the 4.8*35=168 seconds, and the time that electrical heating is closed is 312 seconds.
Step 104：According to the current opening time, electrically heated switch is controlled.
After the electrically heated opening time is determined, you can according to the current opening time, control electrically heated switch.Such as：
Within the cycle of current 8 minutes, electrical heating opens operation 168 seconds to set power, and other are interior in remaining 312 seconds, and electricity adds
Heat is closed.
It can be seen that in the present embodiment, according to the deviation of humidity in the air-conditioning zone of action, PID control is carried out, it is determined that being counted with PID
The air-conditioning electrically heated opening time in the setting cycle of power match is calculated, so as to pass through the electrically heated start-stop within the setting cycle
Time controls electrically heated power output so that electrically heated power output PID corresponding with humidity calculates power match, real
Electrically heated intelligent control is showed, also, electrical heating is not to run always, reduces the consuming of the energy.
To reduce the operating load of air-conditioning, typically, when obtaining smaller in step 102, illustrate very close to setting
Target humidity value, at this point it is possible to without adjusting opening time of the air-conditioning electrical heating in current period, therefore, the present invention is another
In individual embodiment, when current humidity deviation is in setting range, current humidity deviation is defined as zero, and by humidity deviation
Changing value be defined as zero.Such as：-5<ΔRH<5, then Δ RH=0 is can determine that, and the changing value DRH=0 of humidity deviation is determined,
So as to, Δ Heater_p=0, and Heater_p=Heater_p1, so, adjustment air-conditioning electrical heating can not had in current week
Opening time in phase.Typically, in the setting range of target humidity value, it is more approximate that air conditioner user experiences level of comfort,
Therefore, if current humidity deviation is in setting range, when just not having to continue to adjust unlatching of the air-conditioning electrical heating in current period
Between, so, the consuming to resource can be reduced.
In addition, the embodiment of the present invention further can be controlled to the electrically heated opening time proportional difference of air-conditioning, also will
Δ Heater_p is controlled in certain scope, therefore, when the electrically heated opening time ratio of the air-conditioning obtained according to formula (1)
When difference is more than the first setting value, the electrically heated opening time proportional difference of air-conditioning is defined as the first setting value, and, work as root
When the electrically heated opening time proportional difference of air-conditioning obtained according to formula (1) is less than the second setting value, open air-conditioning is electrically heated
Open time scale difference and be defined as the second setting value.
Such as：As Δ Heater_p >=5%, Δ Heater_p=5% is determined, and as Heater_p≤- 5%, really
Determine Δ Heater_p=-5%.
In the embodiment of the present invention, if opening time ratio of the air-conditioning electrical heating in current period is bigger, air-conditioning active region
Indoor temperature and humid control precision in domain is higher, but has higher energy consumption, and air-conditioning electrical heating is in current period
Opening time ratio is got over, and the indoor temperature and humid control precision in the air-conditioning zone of action are lower, therefore, take into account energy consumption and control
Precision processed, can be according to electrically heated performance, the model of air-conditioning, can be for opening time ratio of the air-conditioning electrical heating in current period
Example also can control within the specific limits, so, when unlatching of the air-conditioning electrical heating obtained according to formula (2) in current period
Between ratio when being less than three setting values, be the 3rd setting by opening time ratio-dependent of the air-conditioning electrical heating in current period
Value, and, when opening time ratio of the air-conditioning electrical heating obtained according to formula (2) in current period is more than the 4th setting value
When, it is the 4th setting value by opening time ratio-dependent of the air-conditioning electrical heating in current period.Such as：During Heater_p≤0,
It can determine that Heater_p=0, and Heater_p >=50%, it may be determined that Heater_p=50%.
Certainly, (- 5,5) are not limited in above-mentioned setting range, can be (- 3,3), (- 4, -4) etc.；And the first setting
Value, the second setting value are also not necessarily limited to 5%, -5% or 3%, -3%, or 4%, -4% etc.；Equally, the 3rd setting
Value, the 4th setting value are also not necessarily limited to 0,50% or 1%, 40%, or, 0,35% etc., particularly as not enumerating
.
Below by operating process set into specific embodiment, the method that the embodiment of the present disclosure provides is illustrated.
In the present embodiment, the cycle can be 10 minutes, setting range (- 5,5), the first setting value, and the second setting value is respectively
3%, -3%, the 3rd setting value, the 4th setting value is respectively 0, and 40%.
Fig. 2 is a kind of schematic flow sheet of air-conditioning electric heating controlling method according to an exemplary embodiment, such as Fig. 2
Shown, the process of air-conditioning electric heating control includes：

And following current humidity values obtained in current temperature and humidity value can be passed through.
Rh=A1*T1+B1*T2+C1*hz+E
Wherein, Rh is current humidity value, and T1 is current temperature value, and T2 is interior machine coil temperature value, and hz is compressor operating
Frequency values, A1、B1、C1, E be respectively according to the type of air-conditioning determine constant.
Step 202：Humidity value corresponding to the top n of the current humidity value and current period continuous cycle is weighted
Average calculating operation, obtain current presumption humidity value.
Here, N=11, if current humidity value is Rhn, so that, can be by Rhn, Rhn-1, Rhn-2…Rhn-11This 12 number summations
After remove average, you can obtain current presumption humidity value Rhp.
Step 203：By the difference between current presumption humidity value and the target humidity value of setting, it is inclined to be defined as current humidity
Difference.
Current presumption humidity value Rhp, the target humidity value Rh of settingt, so as to current humidity deviation delta RH=Rhp-Rht。
Step 204：According to current humidity deviation, and the humidity deviation in a upper cycle, the changing value of humidity deviation was obtained.
So as to the changing value DRH=Δ RH- Δs RH of humidity deviation1。
Here, also need to judge Δ RH whether between setting range (- 5,5), if, it may be determined that Δ RH=0, DRH=0.
Step 205：According to formula (1), and formula (2), opening time of the air-conditioning electrical heating in current period is determined
Ratio.
Δ Heater_p=Int ((Heater_Ki×ΔRH+DRH×Heater_Kp) × 100)/100---- formula (1)
Heater_p=Δs Heater_p+Heater_p1--------------------------------------
Formula (2)
Wherein, Δ RH is current humidity deviation, and DRH is the changing value of humidity deviation, Heater_Ki, Heater_KpFor can
The PID calculating parameters of modification, Δ Heater_p are the electrically heated opening time proportional difference of air-conditioning, and Heater_p adds for air conditioner electric

Such as：For the air-conditioning in the present embodiment, Heater_Ki=0.001, and Heater_Kp=0.003, according to Δ RH
=10, and DRH=5, so as to can determine that Δ Heater_p=(0.001*10+0.003*5)=0.025 according to formula (1), i.e.,
2.5%, then, can formula (2) determine Heater_p.
Equally, if Δ Heater_p is more than or equal to 3%, Δ Heater_p=3% is determined, and Δ Heater_p is less than etc.
When -3%, Δ Heater_p=-3% is determined；And Heater_p determines Heater_p=0 when being less than or equal to 0, and Heater_
P is more than or equal to 40%, it is determined that Heater_p=40%.
Step 206：According to default cycle, and opening time ratio of the air-conditioning electrical heating in current period, it is determined that
Opening time of the air-conditioning electrical heating in current period.
Cycle is 10 minutes, therefore, the 1%=6 seconds, so as to which Heater_p=X%, the opening time is the X*6 seconds.
Fig. 3 is opening time computing of a kind of air-conditioning electrical heating in current period according to an exemplary embodiment
