Problems solved by technology
Therefore, the uneven exhaust volume is also a reason for restricting the poor smoke exhaust of users on low floors.
In addition, the existing indoor range hoods basically use constant gear control, that is, when the user clicks on a gear of strong, medium, or weak on the control panel, the indoor range hood can only operate on the performance curve under this gear , and in such a control method, the air volume will change with the change of the rear end resistance (such as the increase of the power-on rate, the increase of the flue resistance, and the decrease of the air volume)
When the smoke exhaust resistance in the public common flue is large, the oil fume is easy to flow backward into the room; when the operating rate is small, the indoor range hood cannot automatically adjust the gear of the range hood according to the overall smoke exhaust resistance of the public flue

The invention relates to a building centralized smoke exhaust system and its operation control method. The building centralized smoke exhaust system includes indoor range hoods, public flue outdoor host systems and cloud servers, and is characterized in that the building centralized smoke exhaust system The operation control method includes: step 1, the indoor range hood is powered on and started; step 2, the electric check valve of the indoor unit lower than the n floor is kept open at 90 degrees, and the opening angle of the electric check valve of the indoor unit higher than the n floor is the α degree; step 3, calculate the actual smoke emission Q 实测 ; Step 4, the indoor range hood sends its own operating status information to the cloud server; Step 5, the cloud server calculates the target smoke emission Q 目标 , and correspond to the indoor range hood issued to the corresponding floor; step 6, judge Q 目标 Is it in the interval [Q 目标 -σ,Q 目标 +σ], if not, adjust the fan speed; step 7, continue to adjust the opening angle of the electric check valve on high floors; the present invention can ensure smooth smoke exhaust.
Description
technical field [0001] The invention relates to a building centralized smoke exhaust system and an operation control method thereof. Background technique [0002] At present, most of the range hoods used in the kitchens of houses and apartments are independent. Holes in the windows or walls are used to set the exhaust port of the range hood. The oil fume is discharged directly from the outer wall, which will cause pollution interference to the residents on the upper and lower floors, and will cause oil pollution to the outer wall. At the same time, it will also affect the overall appearance of the building. [0003] With the high-speed development of economy, more and more high-rise residential buildings have sprung up like mushrooms after rain. In order to maintain the appearance and image of the entire building, in many high-rise residential buildings, a centralized smoke exhaust system for the building will be adopted for centralized smoke exhaust. The public flue, the ...
