Abstract
The present disclosure provides a disinfecting device for a central air conditioner, which uses high-powered ultraviolet rays to efficiently and rapidly eliminate viruses, and uses two sets of parallel reflectors to reflect and overlap light curtains of the high-powered ultraviolet rays back and forth. In this way, small-sized aerosols with viruses can be eliminated, and no secondary pollutants such as ozone are produced in a process of purifying and disinfecting air by the ultraviolet rays. The entire device has a simple structure and can be used in the central air conditioner with an existing architecture. The entire device only needs to be provided in an air supply duct of the central air conditioner.
