According to the relevant requirements of the Technical Specification for Disinfection, the installation quantity of indoor suspended ultraviolet disinfection lamps (30W ultraviolet lamps, with radiation intensity higher than 70μW/ m2 at vertical position 1m) is: average not less than 1.5W per cubic meter, with uniform distribution, and the hoisting height from the ground1.8 ~ 2.2m.

A 60 cubic meter room needs 90W, so generally speaking, three 30W ultraviolet lamps need to be installed.

In order to ensure the disinfection effect, the irradiation time can be appropriately extended when necessary (generally, when ultraviolet irradiation is used for disinfection, it should be continuously irradiated for more than 30min. )

If the disinfection is aimed at the surface of the object, the distance between the lamp tube and the irradiated surface should be kept within 1m, and the disinfection is effective.
