AI Technical Summary

Problems solved by technology

The temperature difference load caused by a certain amount of outdoor low-temperature air being sucked into the room causes a relatively large drop in the indoor temperature, which has a great impact on people's comfort. The above problems limit the wide application of this type of equipment
[0007] However, the state of outdoor air quality, that is, the PM2.5 content in the air, the concentration of carbon dioxide, and the temperature, all have large uncertainties, and the range of variation is often relatively large. Bring obvious flaws and deficiencies

Embodiment

[0051] see Figures 1 to 6 , an air purification device 100, comprising a box body 1, the box body 1 is provided with a fresh air outlet 11 communicating with the outdoor environment, and a return air outlet 12 and an air supply outlet 13 communicating with the indoor environment;

[0052] The fan 2 is used to drive air to flow in one direction between the fresh air port 11 and / or the return air port 12 to the air supply port 13;

[0053] The air volume adjustment mechanism 3 is used to adjust the fresh air volume entering the box body 1 from the fresh air port 11, and the return air volume entering the box body 1 from the air return port 12 is equal to the total air supply volume (fresh air volume+ return air volume);

[0054] The gas concentration sensor 4 is used to collect indoor gas concentration parameters;

[0055] A controller 5, configured to control the air volume adjustment mechanism 3 to adjust the ratio according to the indoor gas concentration parameter;

[0056...

Abstract

The invention discloses an air purification device. The air purification device comprises an air volume regulation mechanism used for regulating the volume of fresh air entering a box body from a fresh air port and regulating the ratio of the volume of return air entering the box body from an air return port to the total air supply volume according to the indoor gas concentration parameters. The invention further discloses a control method of the air purification device. On the basis of purifying indoor air, the air purification device supplies outdoor fresh air with high oxygen content appropriately according to the indoor oxygen content change, and the influence of loads caused by temperature difference between the indoor air and the outdoor air can be lowered to the maximum degree. The air purification device has the advantages of being safe and convenient to use and saving the energy.

Description

technical field [0001] The invention relates to the technical field of air purification and constant oxygen treatment, in particular to an air purification device and a control method thereof applied to crowded indoor places such as classrooms and movie theaters. Background technique [0002] In recent years, the air quality around us has deteriorated year by year, and the number of haze days is increasing. The number of cities with 15% of moderately or heavily polluted days throughout the year is also on the rise. It is no longer news that the PM2.5 index has repeatedly exploded. It has different degrees of impact on people's daily study, life and work. [0003] In the face of severe smog in the air, in addition to taking active measures to prevent and control, it may be a more realistic choice to take protection in daily life. For indoor application places, from the perspective of optional equipment for air smog protection, there are currently two types of optional equi...
