Electronic dibit adjusting air valve 2 12 is connected, and wind turbine 2 14 is equipped in the 4th babinet D.Maintenance door four is equipped on the 4th babinet D
13 and maintenance door 5 15, maintenance door 4 13 and maintenance door 5 15 are located at the front and rear of wind turbine 2 14.
Wind outlet section 16 is equipped in the 5th babinet E, the 5th babinet E is equipped with air outlet.
Wind turbine 1 is connected with one start and stop module 17 of wind turbine and one frequency-variable module 19 of wind turbine, wind turbine 2 14 and two start and stop of wind turbine
Module 18 and two frequency-variable module 20 of wind turbine are connected, one start and stop module 17 of wind turbine, two start and stop module 18 of wind turbine, one frequency-variable module of wind turbine
19, two frequency-variable module 20 of wind turbine, electric multiblade adjusting air valve 5, electronic dibit adjusting air valve 1 and electronic dibit adjusting air valve two
12 are connected with control unit.
One start and stop module 17 of wind turbine and wind turbine two start and stop module 18 is initially used for control wind turbine 1 and wind turbine 2 14
Open/close state, secondly for monitoring wind turbine 1 and wind turbine 2 14 whether normal operation.The opening of wind turbine 1 and wind turbine 2 14/
Off status determines whether it opens by production/on duty, actual load percentage operation.The effect of monitoring is that wind turbine 1 is only
When vertical operation, when it breaks down, closing wind turbine 1, interlocking is opened electronic double on the second babinet B and third babinet C
Position adjusting air valve 1 and electronic dibit adjusting air valve 2 12 enable standby fan 2 14.

It is required that keep frequency is run under 30~60 hertz；Under production status, operating load percentage constant interval is in 50 at full capacity
When~100%, the wind turbine 1, wind turbine 2 14 are opened simultaneously, are controlled its frequency and are run at 50~100 hertz, operating load
Percentage constant interval at full capacity 15~50% when, open the wind turbine 1, close the wind turbine 2 14, control its frequency
Rate is run at 30~100 hertz.
Divide production model, attended mode in actual motion；Cooling in summer operating mode, winter heating's operating mode；In conjunction with different mode
And operating mode enumerates novel two fans convertible frequency air-conditioner case robot control system(RCS) application：
Attended mode, it is intended to maintain the ventilation that room is certain, no humiture to require, the air quantity very little needed at this time,
Usually in air output 30% hereinafter, concrete numerical value can be according to the determination of disparity items.One start and stop module 17 of wind turbine is set to open,
Two start and stop module 18 of wind turbine is closed, and electronic dibit adjusting air valve 1, electronic dibit adjusting air valve 2 12 are simultaneously closed off, and adjusts wind
Feedback information is passed to electric multiblade adjusting air valve 5, adjusts fresh air inlet wind by 19 to 30~60 hertz of one frequency-variable module of machine
Amount.
Under variable air volume running, air output is directly proportional to indoor load.According to load when actual motion and calculate at full capacity
Ratio control wind turbine frequency.For example, cooling in summer operating conditions pattern is with reference to table 1.When 50%~100% load operation,
Setting one start and stop module 17 of wind turbine and two start and stop module 18 of wind turbine are opened simultaneously, open simultaneously electronic dibit adjusting air valve 1, electricity
Dynamic dibit adjusting air valve 2 12, one frequency-variable module 19 of wind turbine and two frequency-variable module of wind turbine, 20 frequency become according to load holding is synchronous
Change, while the frequency information of adjustment is fed back into electric multiblade adjusting air valve 5, adjusts fresh air inlet air quantity.30%~50% is negative
When lotus runs, two start and stop module 18 of wind turbine remains off, and simultaneously closes off electronic dibit adjusting air valve 1, electronic dibit tune
Save air-valve 2 12, one frequency-variable module 19 of wind turbine according to Load Regulation frequency to 60~100 hertz run, by the frequency information of adjustment
Feed back to electric multiblade adjusting air valve 5.
Table 1
Winter load is usually the 50%~60% of Load in Summer, if summer is still maintained to calculate air quantity operation, is necessarily caused
Energy loss.For heating condition control model with reference to table 2, control mode is roughly the same with summer, repeats no more.
Table 2
When single wind turbine independent operating operating mode, wind turbine 1 breaks down, and opens electronic dibit adjusting air valve 1, electricity immediately
Dynamic dibit adjusting air valve 2 12, two start and stop module 18 of wind turbine is kept it turning on, and executes standby fan operation mode.
