Problems solved by technology

[0003] The current method is to manually confirm the static pressure range according to the actual installation environment, and to set the speed of each windshield when the unit is running by dialing or remote control (wire control). This method is not easy to obtain the specific air duct during actual installation. Static pressure value, it is difficult to get the optimal static pressure range that needs to be operated and run

Embodiment 1

[0052] Embodiment 1. A self-adaptive static pressure adjustment method for an air duct machine. Combine below figure 1 with figure 2 The method provided in this embodiment will be described in detail.

[0053] see figure 1 , S1. Subdivide the static pressure in the air duct into a predetermined number of static pressure intervals i according to predetermined rules, and each static pressure interval i corresponds to a corresponding static pressure range P i-1 ~P i and different wind gears, each wind gear corresponds to the corresponding fan operating speed R i and normal current range [I i(P(i)) , I i(P(i-1)) ], the value of i is from 1 to N, where N is a positive integer.

[0054] Specifically, when the fan in the air duct machine is running, the corresponding static pressure will be different for different air ducts in the air duct machine, so the static pressure corresponding to these air ducts is subdivided into a predetermined number of static pressures according t...

Embodiment 2

[0077] Embodiment 2. A self-adaptive static pressure regulating device for an air duct machine. Combine below image 3 The device provided in this embodiment is described in detail.

[0078] see image 3 The self-applicable static pressure adjustment device 30 for air duct machine provided in this embodiment includes a static pressure interval subdivision module 301, a current range determination module 302, a first current value detection module 303, a first judgment module 304, and a first calculation module 305 , a second current value detection module 306 , a second judgment module 307 , a second calculation module 308 and a third judgment module 309 .

[0079] Among them, the static pressure interval subdivision module 301 is used to subdivide the static pressure in the air duct into a predetermined number of static pressure intervals i according to predetermined rules, and each static pressure interval i corresponds to a corresponding static pressure range P i-1 ~P i...

Embodiment 3

[0093] Embodiment 3, an air duct machine.

[0094] see Figure 4 As shown, the air duct machine provided in this embodiment includes the air duct machine self-applicable static pressure regulating device 30 provided in the second embodiment.

Abstract

The invention discloses an air duct machine self-adaptive static pressure adjusting method and device and an air duct machine. The method comprises the steps that static pressure in an air duct is subdivided into a plurality of static pressure sections; the static pressure section i and the static pressure section i+1 are selected, air gears at the static pressure section i and the static pressure section i+1 are detected respectively, and fan rotating speeds Ri and Ri+1 under the air gears and corresponding actual operation current values Ii and Ii+1 are detected; whether Ii and Ii+1 is within the normal current range is judged, and the final static pressure section is determined according to judging results and preset conditions. By means of the method, the air duct machine can automatically select and determine the static pressure sections according to actual mounting environments, the optimal static pressure section for operation of the air duct machine is found out, and precision is high.

Description

technical field [0001] The invention relates to the technical field of static pressure adjustment, in particular to an air duct machine self-adaptive static pressure adjustment method, an adjustment device and an air duct machine. Background technique [0002] For air duct units with a large range of static pressure ranges, the method of subdividing the static pressure ranges is generally used at present, and the air volume of each windshield is designed for each static pressure range, usually by means of constant air volume. When the static pressure value is reached, use the dial code or wire control to set it to the corresponding static pressure range, so as to obtain the operating speed of each windshield. [0003] The current method is to manually confirm the static pressure range according to the actual installation environment, and to set the speed of each windshield when the unit is running by dialing or remote control (wire control). This method is not easy to obtain...
