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.

Climate Center stocks R32 in all its branches

Climate Center claims to be the first distributor to stock the low-GWP refrigerant R32 in every branch — amounting to 45 branches nationwide. R32 is a single-component refrigerant with a GWP of 675, considerably lower than the 2088 for R410A. The investment coincides with Daikin and Toshiba launching R32 air-conditioning ranges.

Advanced Air, FCU, fan coil unit, air conditioning

EC motor enhances Advanced Air fan decks
