Bacterial sterilization / virus inactivation device, air conditioner equipped with the same, and sterilization / virus inactivation method

Abstract

The sterilization / virus inactivation device comprises a microorganism attachment part identification unit that identifies microorganism attachment parts, which are locations within a target space where people enter and exit, where microorganisms are attached, a substance generation unit that generates a specific substance that performs sterilization or inactivation processing of microorganisms, and a transport unit that generates an air flow within the target space and transports the specific substance toward the target microorganisms, and performs sterilization or inactivation processing within the target space.

Claims
