CO2 device, CO2 concentration E in energy real-time detection room are housed at new blower return air inletCO2, as shown in Figure 1, according to
Indoor CO2 concentration ECO2New blower can be divided into Three models: indoor circulation wind mode, mixed wind mode and all-fresh air mode.
Indoor circulation wind mode: indoor CO2 concentration ECO2< 600ppm.
Mixed wind mode: 600ppm≤interior CO2 concentration ECO2≤1000ppm。
All-fresh air mode: indoor CO2 concentration ECO2> 1000ppm.
Indoor circulation wind mode is as shown in Figure 3: when indoor CO2 content be less than 600ppm when, at this time room inner air compared with
It is good, do not have to introduce fresh air, therefore wind circulation pattern in opening chamber.5- mixer selector valve is opened at this time, and 18- fresh air inlet valve is closed,
Indoor return air enters via indoor each air port, and goes out to concentrate in new blower return air inlet by return air duct.Pass through 1- later
Low efficient filter screen 1., 5- mix wind air-valve, 12- fresh-air fan, 4- heat exchanger 1., 3- humidification membrane element, 2- heat exchanger 2., 17- high
Filter screen, indoor air outlet blowout are imitated, and is transported to each room through indoor air hose, and via the air outlet in each room
It sends out.
Mixed wind mode is as shown in Figure 4: most of air needs at this time among 600 ~ 1000ppm in research department
Mixed wind mode is opened, 18- fresh air inlet air-valve is opened after wind mode is opened, and the aperture of 5- mixer selector valve is via PID fuzzy control
Judgement (described in detail below) obtains.After the aperture of mixer selector valve is calculated, fresh air and indoor return air can be from the valves
After entering and mixed out by 12- fresh-air fan, 4- heat exchanger 1., 3- humidification membrane element, 2- heat exchanger 2., 17- high
Imitate filter screen, sent out using indoor air outlet it is outdoor, after through indoor air hose be transported to each room, and via each room
Between air outlet send out.Indoor return air according to the aperture of 5- mixer selector valve, a part by 1- low efficient filter screen 1., 5- mix wind air-valve
Mix later and at 12- fresh-air fan with outdoor fresh air via 4- heat exchanger 1., 3- humidification membrane element, 2- heat exchanger 2., 17-
High efficiency particulate air, indoor air outlet are sent out；Another part via 1- low efficient filter screen 1., 5- mix wind air-valve, 7- heat exchanging core,
10- return air fan, return air inlet outlet discharge are outdoor.Outdoor fresh air passes through the new blower inlet valve of 18-, 9- fresh air sand proof net, 8 slightly
Effect filter screen 2., mix with indoor return air at 12 fresh-air fans after 7 heat exchanging cores after through 4- heat exchanger 1., 3- adds
Wet film component, 2- heat exchanger 2., 17- efficient filter, blown out using indoor air outlet, and be transported to through indoor air hose each
Room, and sent out via the air outlet in each room.
All-fresh air mode is as shown in Figure 5: when indoor CO2 content is higher than 1000ppm, room air is too poor at this time is badly in need of greatly
Amount introduces outdoor fresh air, therefore all-fresh air mode outside opening chamber.If Fig. 2 shows, the valve under new mode, at 18- fresh air inlet
It opens, 5- mixer selector valve is closed.Outdoor fresh air from fresh air inlet enter, through 9- fresh air sand proof net, 8- low efficient filter screen 2., 7-
Heat exchanging core, 12- fresh-air fan, 4- heat exchanger 1., 3- humidification membrane element, 2- heat exchanger 2., 17- high efficiency particulate air is via room
Interior air outlet air-supply is sent to indoor each corner using the default air hose in interior.Indoor return air is dispersed in each room
Return air inlet enter, concentrate at new blower return air inlet, through 1- low efficient filter screen, 5- mix wind air-valve, 7- heat exchanging core,
10- return air fan is exported from outdoor return and is discharged.
The control method of new blower mixer selector valve based on fuzzy-adaptation PID control of the invention is as shown in fig. 6, be that will affect interior
CO2A number of factors and CO of concentration2Concentration itself is used as the input of fuzzy controller, by correcting value Kp ', Ki ', Kd ' it is used as mould
The output of fuzzy controllers obtains the output of fuzzy controller according to the input of fuzzy controller, i.e. acquisition correcting value Kp ', Ki ',
The value of Kd ', then aperture K=Kpo*Kp '+the Kio*Ki '+Kdo*Kd ' of mixer selector valve, wherein Kpo, Kio, Kdo are previously given
