结果，根据韩国工业技术学院（KTL）测试，根据韩国产业技术试验院（KTL）的测试，其浮游细菌的减损率96.7%，浮游病毒的减损率96.8%，臭氧发生浓度0.009ppm。这与韩国臭氧紫外线协会KOUVA AS 02：2019空气净化装置试验标准值——“浮游细菌减损率80%以上，浮游病毒减损率60%以上，臭氧浓度0.05ppm”相比，是非常优秀的性能。特别是，与仅在模块中进行悬浮细菌和悬浮病毒性能测试相比，Daelim Industrial能够在实际使用中展示与使用模块安装产品进行测试时相同的性能。
According to Korean media reports, Daelim Industrial (Korea Dalin Industrial Co., Ltd.) has developed a "antivirus air cleaning and ventilation system" using UV LED photocatalysis technology, and entered the mass production stage for the first time. It is worth mentioning that the compound ventilation device with the addition of cooling and dehumidification modes has completed product development and is planned to be applied.
■ Product development and release speed is very fast
The recent problem with the new crown virus coincides with the fact that the anti-virus air cleaning and ventilation system is running, but the development plan for the ventilation system was formulated in 2017. In the past year and six months, the development progress has been steady. After the planned development, in 2018, the Korean dust topic reached its apex, and the demand for air purification solutions was also very high. Therefore, the ventilation equipment with air purification function was developed in advance to preemptively ensure the Patents, while providing patents, also consider the next generation of products.
Daelim Industrial has always tried to proactively provide solutions by determining which factors will be emphasized in the future and what consumers want.
At that time, the industry and industry analyzed that, related to indoor air quality, after smog, carbon dioxide, and VOCNS, the treatment of biological substances such as mold, bacteria, and viruses will become the main topic. The results of research on related technologies show that UV LED photocatalysts have higher performances such as sterilization and ozone safety, so they have been pushed forward.
Recently, due to the occurrence of new coronaviruses and the increasing demand for virus response solutions, anti-virus ventilation systems prepared to meet market demand have been rapidly released.
■ Sterilization method and antibacterial and antiviral performance
The anti-virus performance sterilization method uses the UV LED photocatalyst method. Compared with existing technologies such as plasma and mercury lamps, its ozone emission is very low, and has few side effects, and has excellent sterilization ability. In the development process, the process of arranging the position of the UV module and the filter has been optimized. Researched how to use the most effective filter to arrange the position of short wave (such as UVC and UVA), how to order the most effective, to ensure the sterilization performance even under high air volume, and to apply the algorithm based on human factors for optimal control.
In this anti-virus ventilation system, the shortest ultraviolet short-wave UVC is directly irradiated to eliminate bacteria and viruses attached to the HEPA filter. In addition, by irradiating with UVA with a longer wavelength than UVC, it also promotes the production of OH⁻ (free radical hydroxide) of the TiO 2 (titanium dioxide) photocatalyst. OH⁻ is a material that is safe for the human body and has excellent bactericidal power and sterilizing power. The generated OH⁻ is widely spread in the ventilation system to disinfect the air passing or trapped.
As a result, according to the Korea Institute of Technology (KTL) test, according to the Korea Institute of Industrial Technology (KTL) test, the reduction rate of planktonic bacteria was 96.7%, the reduction rate of planktonic viruses was 96.8%, and the ozone concentration was 0.009ppm. This is an excellent performance compared with the standard value of the Korean Ozone Ultraviolet Association KOUVA AS 02: 2019 air purification device test standard-"the reduction rate of planktonic bacteria is more than 80%, the reduction rate of planktonic virus is more than 60%, and the ozone concentration is 0.05ppm". In particular, compared with the performance test of suspended bacteria and suspended virus only in the module, Daelim Industrial can demonstrate the same performance in actual use as when the product is installed with the module for testing.
This anti-virus ventilation system not only has anti-bacterial and anti-virus functions, but also adds a variety of functions such as silence, block, air purification, intelligent detection, and artificial intelligence control. Because each element technology is proven, performance and stability are also trustworthy.
The product passed the technical verification of internal and external experts in the development stage, the performance verification of the testing agency in the development completion stage, and the empirical test in the market stage. Therefore, Daelim Industrial plans to designate suitable bases from the second half of this year and introduce them to each generation in turn.
In addition, a combined ventilation system with air-conditioning and dehumidification functions was developed with AOL, and final performance verification is expected to be completed by the end of June.
