[Asia Economy Reporter Kim Jong-hwa] When operating cooling devices during scorching heat, it is easy to mistakenly believe that the indoor air is comfortable due to the cold air temperature. However, if the air conditioner is left on for a long time in a sealed state, polluted air accumulates indoors, which can adversely affect health and, in severe cases, lead to various health problems such as headaches, sore throat, cough, runny nose, and itchy eyes.

Pollutants that worsen indoor air quality, such as volatile organic compounds (VOCs), radon, and carbon dioxide, cannot be resolved by air purifiers, which are representative air quality management appliances, so regular ventilation is essential. Last year, the Central Disease Control Headquarters announced through the "Air Conditioner Usage Guidelines" that when using an air conditioner, ventilation should be done at least once every 2 hours for more than 15 minutes.

Practicing regular ventilation by opening windows while using the air conditioner is not easy. This is because the cool indoor air created by running the air conditioner escapes, and hot, humid air enters, increasing the indoor discomfort index and energy consumption, which is undesirable.

Concerns about electricity bill shocks aside, it can also lead to a shortage of reserve power, which has recently become a social issue. Harmful substances such as fine dust and insects are also unwelcome guests of natural ventilation that requires opening windows. Especially when combined with weather influences such as summer monsoons or typhoons, natural ventilation becomes difficult due to rain entering indoors.

Kyungdong Navien proposes the "Navien Clean Ventilation System" as a smart ventilation method for the cooling season. It is a system that circulates indoor and outdoor air without opening windows to achieve optimal air quality.

This single device can simultaneously perform the roles of an air purifier and a ventilation system, and it can solve many disadvantages of natural ventilation. Since 2006, newly built multi-family housing complexes with more than 100 units have been required to install ventilation devices, so by simply replacing the existing ventilation system, indoor air can be managed like a system appliance with a single device.

Energy Efficiency, Indoor Air Quality Management, and Ease of Use and Maintenance Should Be Considered

Kyungdong Navien identified three essential criteria to consider when choosing a clean ventilation system: ▲energy efficiency ▲comprehensive indoor air quality management ▲ease of use and maintenance.

Energy efficiency is important from both environmental and economic perspectives. It is necessary to check how much of the already cooled indoor temperature loss caused by air conditioner operation can be compensated. In fact, the Navien Clean Ventilation System reduces cooling energy consumption by up to 34% compared to natural ventilation. It can be used without burden, as the monthly electricity bill is less than 10,000 KRW even when operating 24 hours a day.

When introducing outside air, it is important to check how finely the filter can remove harmful substances and whether it can handle pollutants generated inside the home to enjoy comfortable indoor air. Navien’s Clean Ventilation System manages not only particulate harmful substances such as fine dust and ultrafine dust that can be removed by air purification functions but also various gaseous harmful substances in daily life such as carbon dioxide, radon, and volatile organic compounds. Additionally, the clean filter system can handle ultrafine dust particles as small as 0.01㎛.

It should be easy and simple to use like general home appliances. It must be equipped with various convenience features such as an automatic mode that monitors indoor air quality in real time and operates immediately, and filter replacement notifications, so that a comfortable indoor environment with fresh air can always be maintained easily and conveniently.

The Navien Clean Ventilation System displays real-time air quality in color through an air monitor device, offers detailed function modes including automatic and sleep modes, and allows remote control via an app. Moreover, it provides filter replacement notification services and applies an easy method for anyone to remove and install filters.

A Kyungdong Navien official said, "It is a new alternative that maintains indoor air in optimal condition by reducing airborne bacteria by up to 99.2% and airborne viruses by up to 99.1%," adding, "As the importance of clean air throughout the year is emerging, we will continue to lead the development of the domestic clean ventilation market for consumers’ comfortable living environments."
