Abstract

The invention relates to the technical field of image processing and fresh air control, and particularly discloses a fresh air system and a fresh air control method based on 5G network and human flowrecognition. The fresh air system comprises a frequency conversion fresh air ventilator, a plurality of human flow data obtaining facilities arranged in various stores for obtaining human flow data, data transmission equipment used for transmitting signals of the human flow data obtaining facilities to a computer, an electric control valve arranged at the fresh air pipeline inlet position and usedfor controlling the fresh air volume, the computer for controlling air conditioner tail ends, a DDC of a fresh air valve and corresponding lines, storage equipment for storing computer data and the multiple air conditioner tail ends capable of being applied to an air conditioner system. According to the scheme, large-scale carbon dioxide sensor installation in a commercial complex is avoided, thecost and the manufacturing cost are reduced, in the angle of the business side, unnecessary complaints and turnover reduction caused by exposure of carbon dioxide concentration are avoided, and multiple commercial complex factors are considered.

Description

technical field

[0001] The invention relates to the technical fields of image processing and fresh air control. Background technique

[0002] In existing commercial complexes, the energy consumption of air conditioners accounts for a large part of the total energy consumption. However, the thermal comfort in many commercial complex buildings still cannot meet the demand. One important reason is that the actual number of people in commercial complexes will be high. The number of people in the design is limited, and when the density of people in a closed environment is too high, a high concentration of carbon dioxide will be generated. If there is not enough fresh air to dilute and discharge carbon dioxide, it will cause the human body to feel dizzy, palpitations and other discomforts. The demand for the fresh air volume of the fresh air system during operation is much higher than the design value. At the same time, during non-peak hours, due to the lack of personnel, if the ...
