Abstract

The invention discloses a central extractor hood system and a control method thereof. Wherein the central extractor hood system comprises a public flue, an exhaust host, first power distribution valves and terminals, the first power distribution valves and the terminals are located on all floors of a building, the building comprises a high floor group and a low floor group, the high floor group comprises at least one floor, the low floor group comprises at least one floor, and all the floors in the high floor group are provided with second power distribution valves; and the second power distribution valve is used for providing exhaust resistance for the terminal machine. According to the central extractor hood system and the control method thereof provided by the embodiment of the invention, the second power distribution valve is arranged at the inlet of the exhaust pipeline of each floor in the high floor group, so that additional exhaust resistance is provided for the terminal machine of each floor in the high floor group; according to the method, the resistance required to be provided by the first power distribution valve when the start-up terminal of each floor in the high floor group reaches the target exhaust air rate is reduced, the opening degree of the first power distribution valve is increased, then the howling noise is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of central range hoods, in particular to a central range hood system and a control method thereof. Background technique [0002] In the central range hood system, each floor uses a power distribution valve to adjust the resistance to reduce the exhaust resistance of the terminal located on the lower floor, and appropriately increase the exhaust resistance of the terminal located on the high floor, so as to achieve different floors. The exhaust volume of the terminal is relatively balanced. Among them, the opening of the power distribution valve gradually decreases from the low floor to the high floor. When the operating rate of the terminal reaches a certain value, the opening of the power distribution valve on the high floor will be too small, resulting in a larger Howling noise affects user experience. SUMMARY OF THE INVENTION [0003] The invention provides a central range hood system and a control me...
