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

Embodiment Construction
[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0042] Such as figure 1 The centralized smoke exhaust system shown in the building includes N indoor range hoods 11...1N installed in the kitchens of residents on different floors, where N is a natural number. The host system 3, and the cloud server 6, the air outlets of N indoor range hoods 11...1N are all connected to the public flue 2 through the indoor smoke exhaust branch pipe 5, and each indoor smoke exhaust branch pipe 5 is equipped with an adjustable Angle electric check valve 4, the outlet of the public flue 2 is connected with the entrance of the outdoor host system 3, and the outlet of the outdoor host system is directly communicated with the outside through the hood. N indoor range hoods 11 ... 1N and the outdoor host system are all communicated with the cloud server 6, and the cloud server pre-stores the floor position informatio...

The invention relates to a building centralized smoke exhaust system and an operation control method thereof. The building centralized smoke exhaust system comprises indoor extractor hoods, a public flue outdoor host system and a cloud server. The building centralized smoke exhaust system is characterized in that the operation control method of the building centralized smoke exhaust system comprises the steps that 1, the indoor extractor hoods are powered on and started; 2, electric check valves of indoor units lower than the nth floor are kept to be opened by 90 degrees, and the opening angles of electric check valves of indoor units higher than the nth floor are alpha degrees; 3, the actual smoke exhaust amount Q<actual measurement> is calculated; 4, the indoor extractor hoods send the operation state information of the indoor extractor hoods to the cloud server; 5, the cloud server calculates the target smoke exhaust amount Q<target> and correspondingly sends the target smoke exhaust amount Q<target> to the indoor range hoods of the corresponding floors; 6, whether the Q<target> is within the interval [Q<target>-sigma, Q<target>+ sigma] or not is judged, and if not, the fan rotating speed is adjusted; and 7, the opening angles of the electric check valves continue to be adjusted on high floors. By means of the building centralized smoke exhaust system and the operation control method thereof, it can be guaranteed that smoke is exhausted smoothly.
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 ...
