High Performance UV Disinfection in a HVAC System with Integrated Concentrator Optics

Case ID:

This invention is an ultraviolet germicidal irradiation (UVGI) system that disinfects air through ultraviolet C (UVC) radiation. The system has low power consumption and high sterilization and flow rate to both neutralize airborne pathogens and filter all the air inside a room quickly without disturbing the environment inside the room. 

Removal or neutralization of airborne pathogens from air inside a hospital, classroom, restaurant, nursing home, or store can reduce odor, allergens, and pathogens causing infectious diseases. Among the many techniques, UVGI that utilizes UVC light of optimal wavelength in combination with air filters is the most common. 

This UVGI system can operate as standalone or in addition to the existing ventilation system. The configuration can be optimized for high air change per hour (> 10 ach) without sacrificing room comfort and noise level. 

The UVGI market offers a number of commercially available products, ranging from small standalone units for sterilization of individual rooms to large scale screening of industrial HVAC units. However, many products rely on existing air flow systems rather than optimizing air flow and sterilization in an integrated system.
