Description
Technical field
The present invention relates to a kind of building common ducts, more particularly, to a kind of building common duct smoke evacuation system and its control
Method.
Background technique
Currently, high residential building is more and more, high-storey smoke evacuation mostly uses common flue central exhaust, and house height increases
Add, the resistance in entire smokejack is caused to increase.The outlet of high-rise common duct is generally located at the top of floor, and range hood
The power of offer is limited, causes smoke discharging effect undesirable, cooks peak period, lowrise layer oil smoke can not arranged, or even flue occurs
In oil smoke flow backward phenomenon.Currently, there has been proposed " central purge systems in order to solve the problems, such as that existing kitchen ventilator is discharged fume unsmooth
The concept of system ", the main air blower by being placed on common flue top generates power, and cooperates the cooking-fume exhauster blower of user side
To promote smoke discharging effect.However, not only breaking up the dynamic flat of blower due to easily accumulating fat particles on the blade of the main air blower of roof
Weighing apparatus causes noise to increase, vibration aggravation, but also periodic cleaning is needed to safeguard, maintenance is cumbersome.Also, main air blower is arranged
On common air exhaust passage, the increase of system exhaust resistance will lead to.Especially when number of floor levels is greater than 35 layers, attic main air blower
The negative pressure of generation can not be handed on effectively, the case where leakage pressure occur, and discharging fume on low layer user, it is almost nil to influence, and be caused instead
Energy waste.In conclusion needing to be further improved existing common duct smoke evacuation system.
Summary of the invention
