Problems solved by technology

CN105674400B discloses an air-conditioning plasma air purification combination module, however, the plasma generator needs to consume a large amount of electric energy, which increases the energy consumption of the air-conditioning and the plasma generation process will be accompanied by the formation of ozone, which will cause damage to human health
Air fresheners or spices essentially improve the freshness of the air by masking the smell, and do not fundamentally eliminate the pollution, the pollution still exists, and a large number of volatile organic compounds in the air fresheners will cause secondary pollution
[0004] To sum up, there are obvious deficiencies in plasma technology, photocatalysis technology and fragrance masking, and air resistance and energy consumption must be considered during the use of air conditioners, which requires that the purification device must have the characteristics of low wind resistance and low energy consumption
