Energy efficient EU units used in new Broadcast studio in Korea

Working for the Munhwa Broadcasting Corporation (MBC), the public broadcaster in South Korea, Fläkt Woods has supplied 98 customized EU Air Handling Units with Rotary Heat Exchangers for a new headquarters and studio being created at Digital Media City (DMC) a high-tech complex in Seoul.


Under a contract for main contractor Hyundai, Fläkt Woods is providing the EU air-handling units utilising Rotary Heat Exchangers, which will help to reduce energy costs on summer cooling. Ho-Yong Jeong at the Company explains, “Using our expertise in Heat Exchangers, the engineers have produced an energy efficient method of providing dehumidification to the primary fresh air in order to avoid problems with condensation.”

Fläkt Woods has worked extensively with the Hyundai Development Company and based on this long term working relationship, Fläkt Woods in Korea outlined the technical benefits of EU AHU’s and Rotary Heat Exchangers and Hyundai submitted its proposals, citing these solutions and was awarded the contract.

As well as the need for economic performance by virtue of low energy consumption, a critical requirement was the need for optimum acoustic properties, so low noise output was another reason why the EU air handling units were selected.

In winter, the heat of the exhaust air is taken up by the aluminium rotor, which then delivers the heat to the supply air and vice versa in summer. Rotary heat exchangers are used when the supply and exhaust air ducts converge at one point.

The EU units are being assembled on-site and the delivery will take place in March to June 2012. As the DMC project nears completion, MBC will move to the new campus, closing their existing location and relocating completely in 2013.

Digital Media City spreads over an area of 570,000 sq meters and is a high-tech city centered on Digital Media Street for broadcasting, movies, games, music, e-learning and related industries. It has attracted well-known high-tech companies such as LG Telecom, Pantech and LG CNS, as well as various kinds of public exhibition facilities including the Korean Film Archive and the Korean Film Museum.
