Daelim Develops System Capable of Air Purification, Cooling, and Sterilization

[Asia Economy Reporter Onyu Lim] Daelim Industrial announced on the 10th that it has developed the industry's first anti-virus ventilation system and filed a patent for it.

The system developed by Daelim removes viruses by equipping an air-purifying ventilation system with an ultraviolet light-emitting diode (UV LED) photocatalyst module. UV LEDs have minimal side effects on humans and the environment while providing excellent sterilization effects. In fact, Daelim's anti-virus ventilation system was evaluated to have achieved a 99.9% reduction rate of airborne viruses, a 99.5% reduction rate of airborne bacteria, and an ozone generation concentration of 0.009 ppm, according to test results from the Korea Testing Laboratory (KTL).

The anti-virus ventilation system can solve ventilation, ultrafine dust, and virus removal all at once. In 2016, Daelim developed the industry's first 'air-purifying ventilation system' capable of removing ultrafine dust, verified by a Yale University professor. This system combines air purification by installing an H13-grade HEPA filter in the ventilation device mounted on the ceiling of the outdoor unit room. The H13-grade HEPA filter can remove 99.97% of ultrafine dust particles with a size of 0.3 ㎛ or larger. On days with heavy outdoor fine dust, it operates in air purification mode to circulate indoor air, maintaining clean indoor air quality 24 hours a day. The clean air purified through the ventilation system is evenly delivered throughout the house, including the master bedroom, living room, and kitchen, via supply and exhaust ducts connected like a spider web on the ceiling.

Daelim has also added dehumidification and cooling functions. When the ventilation system is operated, it maintains temperature and humidity within a comfortable range for people within 10 minutes at an indoor temperature of 28°C. In particular, efforts have been made to reduce operational noise, which is only about 35 dB during operation. This is lower than the low-noise mode of typical home air conditioners (about 42?45 dB). Residents can sleep in a quiet environment even while the system is running, unlike other existing ventilation systems.

Moreover, the system automatically maintains comfortable indoor air quality without the customer needing to pay attention. Last year, Daelim developed an integrated air quality management sensor. This sensor detects fine dust, volatile organic compounds, and carbon dioxide concentrations in real time. When pollutants occur, the ventilation system automatically operates as a smart system.

Lee Jae-wook, head of Daelim Industrial's housing equipment team, said, “Daelim is the first in the industry to implement air purification, sterilization, cooling, and dehumidification functions all at once with a single ventilation system,” adding, “We are researching ways to apply new materials so that the ventilation system itself can have perfect sterilization capabilities.”
