Title: Cheng-Ping Chang: Innovator in Air Sterilization Technology
Introduction
Cheng-Ping Chang is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of air sterilization technology, holding a total of 4 patents. His innovative designs focus on improving air quality and reducing contamination in various environments.
Latest Patents
One of Cheng-Ping Chang's latest inventions is an air sterilization device with low aerosol bounce. This device includes an air conditioning pipe, a porous filter media, and a UV light generator. The porous filter media is secured on a fixing portion and features many irregularly distributed channels. These channels are coated with a layer that has a thickness between 10 µm to 1000 µm, which helps to stick aerosols and avoid the bounce effect. The UV light generator emits UV light to kill biological aerosols, making it suitable for long-term usage. This invention significantly reduces the bounce effect of aerosols while maintaining a high flow rate in the air conditioning system and keeping maintenance costs low.
Another notable invention is the push-pull type ventilation hood. This device features a push device to create a push air flow and a pull device to exhaust contaminant flow through an exhaust opening. The two devices are properly coordinated, allowing the contaminated flow of the push air to be effectively exhausted. This design enables the creation of a push-pull hood with the highest efficiency of push velocity, economically and effectively controlling the contaminant source.
