Centralized fume exhaust system for building

Abstract

The invention relates to a centralized fume exhaust system for a building. The centralized fume exhaust system comprises a first type indoor range hood, a public flue and an outdoor main fan system, the first type indoor range hood is in communication connection with the outdoor main fan system through LoRa wireless transmission technology or NB-IoT wireless transmission technology. The centralized fume exhaust system is characterized in that the system further comprises a second type indoor range hood and a cloud server, wherein the second type indoor range hood is in communication connectionwith the cloud server through a WIFI module, and the outdoor main fan system is also in communication connection with the cloud server through a wired network or a wireless network; the correspondingrelational expressions of indoor motor current gears, indoor motor rotating speeds and indoor range hood air volumes are stored in the first type indoor range hood and the second type indoor range hood; the outdoor main fan system drives indoor motors in the first type indoor range hood and the second type indoor range hood by adopting a constant air volume control mode.

Description

technical field [0001] The invention relates to a building centralized smoke exhaust system. 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 outdoor main fan system installed on the...

AI Technical Summary

Problems solved by technology

In the current building centralized smoke exhaust system, the outdoor main fan system and the indoor range hood basically use LoRa modules or NB-IoT modules and other high-penetration, low-speed network communication modules for communication connection due to interference such as floor concrete (wifi modules cannot Penetrating multi-layer floors), but if there is a range hood equipped with a wife module in the system, the system is often not compatible, so it is impossible to uniformly control the range hood equipped with a wife module
