Ozone and ultraviolet technology are commonly used non-contact physical and chemical disinfection methods in space disinfection, and their core role is to kill microorganisms (bacteria, viruses, fungi) in the air and on the surface of objects.
Comparison table of ozone and ultraviolet space disinfection
Contrast dimensions | 臭氧 | 紫外 |
Mode of action | Gas (Diffusion) | Light (Linear Propagation) |
Disinfect dead corners | No dead ends (penetrable gaps) | There are dead corners (affected by occlusion) |
Effects on the human body | Unmanned environment (irritating gases) | Uninhabited environment (burns to skin/eyes) |
Applicable space types | Closed, multi-crevice (lab/cold storage/cabinet) | Open, less obstructed (workshop/classroom/hallway) |
Running costs | The equipment cost and power consumption are high, and the generator consumables need to be replaced for maintenance | The cost of the equipment is low, and the maintenance is only to change the lamp |
Additional features | Remove odors and break down VOCs | Only sterilization, no deodorization function |
Recovery time after disinfection | Ventilation is required for 1-2 hours before entry | Enters when closed (no residue) |
Application scenarios
l Preferred ozone: If the space is confined (such as laboratories, pharmaceutical cold storage, wardrobes), there are many gaps or need to be deodorized at the same time, choose ozone technology to ensure that there are no blind spots for disinfection and improve air quality.
l Prefer ultraviolet: If the space is open (such as production workshops, school classrooms, office building corridors), the frequency of disinfection is high (such as 1-2 times a day), and there is no need for deodorization, choose ultraviolet technology to reduce cost and operational complexity.
l Combined use scheme: In scenarios with high cleanliness requirements (such as food processing workshops and hospital clinics), the mode of weekly deep disinfection of ozone (removing dead spots + deodorization) combined with ultraviolet daily routine disinfection (rapid sterilization)" can be adopted, taking into account comprehensiveness and efficiency.
