Abstract

The invention provides a fresh air purifying machine capable of controlling the air quality according to the outdoor air situation and the indoor sealing condition. The fresh air purifying machine comprises a fresh air access and an air exhausting access, wherein the fresh air access is composed of a fresh air inlet, an air inlet fan, a heat exchanger, a purifying module and a fresh air outlet, and the air exhausting assess is composed of an air exhausting inlet, an air exhausting fan, the heat exchanger and an air exhausting outlet. The fresh air purifying machine further comprises an air detecting unit, a network unit and a control unit. The air detecting unit is used for detecting the concentration value of indoor carbon dioxide. The network unit is used for obtaining the outdoor pm2.5 concentration value. The control unit is used for opening the fresh air assess and the air exhausting access when the concentration value of the carbon dioxide is larger than a first threshold value and the outdoor pm2.5 concentration value is smaller than a second threshold value with the flow of the air inlet fan being larger than the flow of the air exhausting fan, and opening the fresh air access and closing the air exhausting access when the outdoor pm2.5 concentration value is larger than the second threshold value.

Description

technical field [0001] The invention relates to an indoor fresh air system in the air cleaning technology, in particular to a fresh air purifier. Background technique [0002] As the smog becomes more and more serious, the impact of air on health is increasing, and people are paying more and more attention to air quality. Air purification technologies that can reduce PM2.5 indicators are also booming. [0003] Among them, air purifiers can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and can effectively improve air cleanliness. But its defect is that it cannot produce oxygen, and for a closed room, it will cause the oxygen concentration to drop. [0004] The fresh air purifier, while solving air pollution, uses outdoor fresh air to update the indoor air polluted by living and living processes, so as to keep the cleanliness of the indoor air up to a...
