Specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
With reference to shown in Fig. 1, present invention firstly provides a kind of Kitchen in High Rise Apartment aggregate with outliers variable air rate device, including:
Aggregate with outliers 2, through each floor of high residential building;Multiple kitchen exhaust arms 3, respectively in each floor of the high residential building
And connect with the aggregate with outliers 2, and each described kitchen exhaust arm 3 is mounted on lampblack absorber 4;Roof ventilator 1, it is and described
The top connection of aggregate with outliers 2;Multiple signal pickup assemblies 5, are respectively arranged at each described lampblack absorber 4 for recognizing each
The position signalling and keying signal of the lampblack absorber 4 are gathered and are sent after the state of the lampblack absorber 4;Signal processing apparatus 6, lead to
Cross signal transmission passage to be connected with the signal pickup assembly 5 and the roof ventilator 1 for receiving the position respectively
The position of the lampblack absorber 4 having turned on is counted after signal and the keying signal and quantity is sent to the roof ventilator 1
VFC is instructed.
Specifically, the roof ventilator 1 receives opening for the air draft total amount after VFC instruction and the lampblack absorber 4
Open quantity to be directly proportional, the design exhaust air rate of kitchen exhaust arm 3 × lampblack absorber 4 described in the air draft total amount=each floor
The sum of installation × maximum concurrent signatures.More preferably, the maximum concurrent signatures and number of floor levels are in negative correlation
Relation, numerical upper limits are 0.6.The signal transmission passage includes the signal non-wireless means for being connected in parallel in each lampblack absorber
Or signal wireless device, the signal collection device for being connected to the roof ventilator and signal integration device.
Meanwhile, the signal processing apparatus 6 are stored with the various operations under the correspondence difference operating mode of the roof ventilator 1 frequently
Rate, the operating mode are the open position of the lampblack absorber 4 and open quantity;When the signal processing apparatus 6 receive institute's rheme
After confidence number and the keying signal, i.e., compare with the various described running frequency for being stored and respond out to should be under operating mode
The running frequency of the roof ventilator 1.Further, with suitable minimum air quantity, it is ensured that each floor smoke discharging effect.
With reference to shown in Fig. 1 and Fig. 2, the present invention also provides a kind of Kitchen in High Rise Apartment aggregate with outliers VAV control method,
Above-mentioned Kitchen in High Rise Apartment aggregate with outliers variable air rate device also can be implemented by the method, and the process of the control method includes:
In the present embodiment, the exhaust air rate of each layer lampblack absorber 4 is needed for each layer kitchen exhaust, and the air draft of roof ventilator 1
Amount is while opening the exhaust air rate sum of lampblack absorber 4.Lampblack absorber 4 by resident family's control, i.e., is needed to open or is closed according to resident family completely
Close.Signal pickup assembly 5 should have two functions:One is the variable condition for recognizing lampblack absorber 4, and two is the unlatching for gathering lampblack absorber
Or shutdown signal.When signal pickup assembly 5 judges that 4 state of lampblack absorber changes, that is, gather the shape of now lampblack absorber 4
State, and pass to signal processing apparatus 6.Signal processing apparatus 6 should be able to obtain two kinds of signals, including the state of lampblack absorber 4 and right
Answer the position of the lampblack absorber 4 of variable condition.Signal processing apparatus 6 are by statistics 4 open position of lampblack absorber and open quantity, to room
Top fan 1 sends control instruction, so as to improve or reduce blower fan frequency, meets each layer kitchen exhaust demand, and ensures that system is low
Run under energy consumption, system control process is as shown in Figure 2.
Specifically, during the use of 2 variable air rate device of Kitchen in High Rise Apartment aggregate with outliers, ensure first at least
Lampblack absorber 4 in one layer of kitchen is normally-open, as long as there is one layer of lampblack absorber 4 to open, roof ventilator 1 is also opened.
In signal processing apparatus 6, store different operating conditions first, i.e., it is different to open blower fan under quantity and open position
Running frequency, when signal processing apparatus 6 obtain operating condition signal when, by analysis go forward side by side line retrieval correspondence, find out correspondence
Operating mode, you can frequency conversion instruction is sent to blower fan.
After completing above-mentioned implementation process, the following characteristics of the present invention should be able to be embodied:
1) the total exhaust air rate design based on unlatching rate, using concurrent signatures method for designing, carries out system total blast volume
Design is calculated, and reduces blower fan configuration.Specifically, as each layer user of high residential building is using the Time Inconsistency in kitchen, so being
Each branch road of uniting can not possibly be present while utilization rate while open.And in the system the total exhaust air rate of system design, by
Maximum concurrent signatures determine that is, the total exhaust air rate of system=each layer design exhaust air rate × floor sum × maximum is simultaneously using system
Number;
2) the change air draft amount control method based on signal transmission, is adopted by the live signal to opening and open position
Collection and process, adjustment fan operation air quantity and pressure head, maximum possible reduce system operation energy consumption.Specifically, in every layer of lampblack absorber
A signal pickup assembly is installed at place, and when resident family is turned on and off lampblack absorber, signal pickup assembly gathers the unlatching of lampblack absorber
Or shutdown signal, signal processing apparatus are passed to together with lampblack absorber position signalling;Signal processing apparatus by transmit come
Signal carry out Treatment Analysis, the unlatching quantity and open position of the abstract moment lampblack absorber, as control roof ventilator according to
According to, and frequency conversion instruction is sent to roof ventilator with this, the smoke discharging effect in each layer kitchen is ensured with lowest energy consumption.
