Step S203, many design temperatures of collection areal are the service data of T11 air-conditioning, calculate and estimate power consumption
W1；
Quantity in view of a certain regional same model can be different, and we provide to gather 100 skies of areal
The power consumption situation transferred at a temperature of row estimation T11.The air-conditioning of same model is paid the utmost attention to, when the air-conditioning of same model inadequate 100
During platform, then randomly select and gather enough 100.The power consumption at a temperature of T11 is estimated according to the weighted average of this 100 equipment power dissipations
W1。
Wherein, W1 circular is as follows：
The power consumption calculation method of each the first air-conditioning is identical with formula 6, and the air-conditioning of areal first has n platforms in T time,
Wherein, n=100, respective run time is tix, n=1,2 ..., n；X=1,2 ..., s, and

When working as m=n, i.e. m=100, αi=1, calculate 100, the average corrected output of the first air-conditioning
Work as m<When 100, then row coefficient amendment is entered according to corresponding energy consumption grade and a number, calculate 100,
The average corrected output of one air-conditioning
Finally, according to calculatingPower consumption W1 is estimated in calculating：
Step S204, according to the actual power loss W2 for estimating power consumption W1 and user's air-conditioning, calculates 10:00-11:00 economize on electricity
Amount.
Correction factor with reference to table 1, table 1 have recorded over 1 year phase same horsepower same consumption energy grade equipment mean unit
Energy consumption.
For example, a certain regional user's air-conditioning is 1p, two grades of energy consumptions, run at a temperature of T11 regulations to T12
1 hour, this area, the air-conditioning of same model is set within this hour at a temperature of T11 60, then this 60
Correction factor α1-60=1, remaining 40 are extracted in the air-conditioning for other models being set within 1 hour at a temperature of T11,
Assuming that we take out is 1p entirely, 1 grade of energy consumption, then this 40 correction factor is α61-100=A12/A11.
Then estimate power consumption W1 of user's air-conditioning under T11 design temperatures is:
Above-described embodiment gives a kind of embodiment of air-conditioning power consumption estimation method of the invention, in above-described embodiment
In, according to the model and each first air-conditioning of 100 the first air-conditionings 10:00 to 11:00 operational factor, calculates second empty
Adjust, i.e. user's air-conditioning is 10:00 to 11:00 this 1 hour estimate power consumption.Calculated in compared with the prior art by experimental data
For mode, the air-conditioning power consumption that the present embodiment is conversed is more accurate.
