Embodiment Construction

[0020] The present invention will be further described in detail below with reference to the drawings and specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0021] An energy-saving control method for fresh air partitioned air outlets. Multiple partitioned air outlets are connected to a controller through a 485 bus, and the controller is connected to a fresh air fan or an exhaust fan of a fresh air system through the 485 bus. If it is detected that one or more air outlets are open, the matching air volume gear will be calculated according to the following calculation formula.

[0022] For AC fan (relay control), sum represents the sum of all tuyere gear position requests.

[0023] When sum> 0 o'clock:

[0024] ①sum

[0025] ②sum≥N*4 / 3 and sum

[0026] ③sum≥N*4 / 3*2, high-end operation

[0027] When sum=0:

Abstract

The invention relates to an energy-saving control method of fresh air partition wind openings. Multiple partition wind openings are connected with a controller through communication lines, the controller is connected with a fresh air fan or exhaust fan of a fresh air system through a communication line, when opening of a certain or multiple wind openings is detected, the matching wind amount gearis calculated according to the following calculation formula, sum expresses the sum of gear requests of all wind openings, when sum is smaller than N*4/3, low-gear running is achieved, when sum is larger than or equal to N*4/3 and smaller than N*4/3*2, middle gear running is achieved, when sum is larger than or equal to N*4/3*2, high gear running is achieved, when sum is equal to 0, the fresh airfan and the exhaust fan stop working, and when any wind opening is started again, the fans recover to corresponding gears to continuously run. According to the opening number of the partition wind openings, wind amount matching is achieved, the fans run on different gears according to the opening number of the partition wind openings, the fans can be more reasonably used, and unnecessary waste canbe reduced.
