Fig. 1 is the flow chart of the method for natural wind simulating according to embodiments of the present invention.As shown in figure 1, this method includes
Following steps：
Step S102, gather the sample data of natural wind and extract the characteristic parameter in sample data.The mould of the embodiment
Oceanic winds, grassland wind and forest wind etc. can be simulated by intending the method for natural wind.Simulate which kind of natural wind just gathers which kind of natural wind
Sample data and extract corresponding characteristic parameter.Every kind of natural wind is owned by characteristic parameter the characteristics of to one's name, therefore,
According to these characteristic parameters with regard to corresponding natural wind can be simulated.So, in order to obtain these characteristic parameters, in collection certainly
Can gathers in the area such as ocean, grassland and forest during the sample data of right wind, so as to ensure that the characteristic parameter energy of extraction

Compared to the mechanical blowing of dullness, natural wind has following notable six big feature：
Spectral characteristic：The power spectral density distribution of natural wind wind speed meets 1/f rules, and wind velocity fluctuation has 1/f turbulent fluctuations special
Property, the β value of wind speed power spectrum is maintained at 1.5 or so, has obvious spectral characteristic.
Wind speed characteristics：The VELOCITY DISTRIBUTION of natural wind is in obvious partial velocities, and the wind speed accounting lower than mean wind speed is big, machinery
Wind velocity is in normal distribution.
Turbulence intensity：The fluctuations in wind speed of natural wind is larger, and turbulence intensity is more than mechanical blowing.General turbulence intensity Tu is more than
0.5。
Ripple frequency：There is good cooling effect, fluctuations in wind speed frequency exists in the range of air motion frequency 0.3-1.0Hz
0.4Hz or so.
Big whirlpool length：The big whirlpool length dimension L of air-flow is larger, and the big whirlpool length dimension L values of indoor air flow and interior are actual
Space scale approaches；
Wind direction characteristic：The wind direction change with time of natural wind, in longer time span, natural wind by when cardinal wind
Show relatively stable feature.In shorter time span, natural wind by when the wind direction moment all changing.
Because natural wind is as characterized above, therefore, it is average when extracting characteristic parameter can to extract air themperature, air
At least one of speed and air-flow turbulivity.When natural environment air temperature is higher, air average speed is smaller, air stream turbulence
Degree is smaller；When natural environment air temperature is relatively low, air average speed is larger, and air stream turbulence degree is larger.
Step S104, characteristic parameter is input in the model for characterizing thermal comfort index to correct characteristic parameter, repaiied
Characteristic parameter after just.Thermal comfort index and PMV-PPD indexs, it is a kind of index evaluated blowing comfortableness.This refers to
Target numerical value is bigger, and meaning rate with thumb down is higher, that is, comfortableness of drying is poor；Numerical value is smaller, and meaning rate with thumb down is lower, i.e.,
Comfortableness of drying is higher.Therefore, it is modified by the way that the characteristic parameter of extraction is input in thermal comfort index so that amendment

<During 0.05m/s, v=0.05m/s is taken；Tu is turbulence intensity,WhereinIt is the standard deviation of fluctuations in wind speed,
Percent dissatisfied index PD is relevant with air themperature, air average speed, air stream turbulence degree, and is influenceed by average speed
Maximum, air themperature reduce then percent dissatisfied increase；Mean wind speed improves then percent dissatisfied increase；Turbulivity increase is then unsatisfied with
Rate improves.Air themperature, air average speed and air-flow turbulivity are jointly controlled by control, reduce the dissatisfied of blowing
Rate.Percent dissatisfied is adjusted by adjusting air themperature, average speed and air-flow turbulivity, can be with when percent dissatisfied is relatively low
Draw revised characteristic parameter.
Because natural wind has low wind speed last longer, high wind speed continues the partial velocities characteristic of short period, because
This, control sequential is generated according to the wind speed distribution characteristics of natural wind, mean wind speed, maximum wind velocity and minimum windspeed.Control sequential
Change in periodicity sinusoidal function, the control sequential of generation is as shown in Figure 2.Wherein, instantaneous wind speed=mean wind speed+fluctuation wind
Speed, i.e.,
Y=X+A sin (2 π ft), X are mean speed, and A is fluctuation rotating speed.
The instantaneous velocity of air flow any instant is represented byWhereinIt is average speed, v ' is speed
Fluctuation.Tu turbulence intensities are defined as the ratio between standard deviation and average speed of velocity perturbation, i.e.,It illustrates one section

For example, as shown in figure 4, current indoor environment temperature is less than 25 DEG C, mean speed is middling speed, and fluctuation of speed amplitude is
± 50, then the wind of air-blower control output mean wind speed, i.e. middling speed, after 5s, motor is increased by the change controlled wind speed of rotating speed
Greatly, and 3s is continued, then motor controls the change of rotating speed wind speed is returned to mean wind speed again, and continues 5s.Then, motor control
Device rotating speed processed reduces wind speed, and returns to mean wind speed after low-speed region continues 10s.This process is exactly a circulating cycle
Phase, the fluctuating range of motor speed is ± 50.Blower fan and motor in air conditioner coordinate jointly so that in the process entirely blown
In blown according to cycle period, according to above-mentioned control sequential export wind be natural wind simulating.
From the parameter in the model of sign thermal comfort index, indoor environment temperature, mean wind speed and turbulivity influence

Four periods, include according to control sequential output natural wind：In first time period, second time period, the 3rd period and the 4th
Period once exports wind corresponding to mean wind speed, the wind higher than mean wind speed, wind corresponding to mean wind speed and less than average wind
The wind of speed；Or mean wind speed is once exported in first time period, second time period, the 3rd period and the 4th period and is corresponded to
Wind, the wind less than mean wind speed, wind corresponding to mean wind speed and the wind higher than mean wind speed.
As shown in Figure 4 and Figure 5, each cycle period includes the wind higher than mean wind speed and the wind less than mean wind speed,
And the duration higher than the wind of mean wind speed is less than the duration of the wind less than mean wind speed, the nature simulated with this
Wind is more gentle comfortable.Because the wind direction moment of natural wind is all changing, still, in longer time span, natural wind
Relatively stable characteristic is presented in cardinal wind, therefore, using cardinal wind of the mean wind speed as natural wind simulating, with 3s to 5s mono-
