In comparative example 6, the air sterilizer used a double suction centrifugal fan and discharged air from the top, and the average air age was 510S. Compared with the air age simulation analysis of the air age and the air age simulation analysis of the air age, the technical scheme of the embodiment has the advantages of lower air age, higher space airflow circulation speed and better disinfection effect. The reason is that compared with the comparative example 6, the air is easy to sink and not easy to flow and diffuse around by adopting a top air outlet mode; in the embodiment, the two air outlets are vertically arranged for air outlet, and the air outlet is horizontally forward, so that the air flow circulation speed is higher.
