Embodiment 1

[0044] This embodiment provides a method for controlling the air volume of a central flue, which includes the following steps, such as figure 1 Shown:

[0045] S1. Start the indoor hood and detect in real time whether there is any smoke from the indoor hood; if there is no smoke, go to S2; if there is smoke, go to S3;

[0046] S2. Reduce the air volume of the indoor hood until it reaches the minimum air volume that keeps the indoor hood free of smoke;

[0047] S3. The indoor smoke machine increases the air volume, and reports the smoke leakage information to the outdoor control system;

[0048] S4. After the outdoor control system receives the information of running smoke, it controls the outdoor main fan to start, and the outdoor main fan runs at a certain gear, so that the reported indoor hoods have no running smoke, and the unreported indoor hoods further reduce the air volume , until it reaches the minimum air volume that keeps the unreported indoor hood free of smoke. ...

Embodiment 2

[0066] Such as image 3 and Figure 4 As shown, this embodiment provides a central flue control system, including an indoor smoke machine 1 installed on each floor, an outdoor control system and a smoke detection component 3;

[0067] The smoke detector component 3 is connected with each indoor smoke machine 1, and is used to detect whether the indoor smoke machine 1 runs out of smoke; the outdoor control system includes an outdoor main fan 2 installed at the air outlet of the public flue 4, and the outdoor control system is connected with each indoor smoke machine. The smoke machine 1 is connected by communication, and is used to control the opening, closing, and gear adjustment of the outdoor main fan 2 according to the received information sent by the indoor smoke machine 1 .

[0068] Because the smoke sensor component is connected with the indoor hood, it can accurately judge whether the indoor hood is running out of smoke; and because the outdoor control system communica...

Abstract

The invention belongs to the technical field of central flue systems, and discloses a central flue air volume control method and system. The method comprises the following steps that an indoor range hood is started, and whether smoke escapes from the indoor range hood in real time or not is detected; if not, the indoor range hood reduces the air volume until the indoor range hood keeps the minimumair volume without smoke leakage; otherwise, the indoor range hood increases the air volume, and reports the smoke leakage information to an outdoor control system; and after the smoke leakage information is received by the outdoor control system, the outdoor control system controls an outdoor main fan to be started and enables the outdoor main fan to run at a certain gear, so that the indoor range hood with the information reported has no smoke leakage and the indoor range hoods without information reported to further reduce the air volume until the indoor range hoods without information reported keeps the minimum air volume without smoke leakage. With the control method, reasonable distribution of power can be implemented, the practicability of the whole central flue air volume controlsystem is improved, and noise and energy consumption are reduced as much as possible while the smoke suction effect of the indoor range hoods of all floors is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of central flue systems, and in particular relates to a central flue air volume control method and system. Background technique [0002] In recent years, a concept of "concentrated fume exhaust system for building public flue" has emerged as the times require, which generates additional power through fans placed at the top of the public flue, and cooperates with the indoor range hoods of each household to achieve uniform air volume on each floor Distribution, so as to achieve the purpose of smooth smoke exhaust and low noise use. [0003] However, this method of evenly distributing the air volume of each floor is a relatively blind control method, and the air volume allocated to each household is not high. In addition, in the actual use process of users, each household's demand for air volume at the same time period is inconsistent. , the method of evenly distributing the air volume of each floor cannot be ...
