Lindab, chilled beam, air conditioning

Lindab chilled beams in landmark building

Lindab’s Solus chilled-beam system has been chosen to deliver energy-efficient climate control for a landmark building in Sweden — the Round House in the Munksjöstaden district. Pairing Solus with renewable-energy sources such as free cooling and ground-source heat pumps can achieve energy savings of up to 45%. The system includes nearly 600 Solus chilled beams and the entire ducting system. Pascal VAV system are being used in areas where the heating load can change very quickly, such as conference rooms.
