Product Description
The WAAB-4WAY Active Chilled Beam is an air/water induction terminal unit that simultaneously provides thermal treatment and diffusion of supply air. Chilled beams take advantage of the excellent thermal properties of water to guarantee optimal comfort levels with minimal power consumption. The WAAB-4WAY model can be adapted to modular ceilings measuring 24″ x 24″, or metric dimensions 600×600 mm, 625×625 mm and 675×675 mm, for T24 and T15 tegular profiles. Thanks to its reduced size, it can also be installed in low-hanging false ceilings. WAAB-4WAY supplies air in a 4 Way diffusion pattern.
High thermal capacity is achieved thanks to its induction principle. Once conditioned in a treatment unit, primary air is expelled through induction nozzles. This creates a pressure drop which forces the air in the premises to pass through the water battery, where the required air-water heat exchange takes place. Induced air is then mixed with primary air prior to being diffused in the room, continuing the cycle. This induction process allows an active chilled beam to provide much more cooling capacity than a passive chilled beam.
The main heat-transferring component in the WAAB-4WAY chilled beam is a battery, formed by copper tubing and aluminum blades. WAAB active chilled beams also incorporates air duct and water pipe connections, a plenum for mixing fresh air with induced air, which has been previously treated in a central air conditioning unit. The WAAB-4WAY chilled beam can be supplied with connections on the side or on the top for both supply and return. The unit can be adapted to medium panel modular ceilings. It can be installed in low-hanging false ceilings thanks to its compact size.
Active chilled beams systems can help reducing energy consumption and meet the energy efficiency requirements of the Federal Energy Policy Act (EPAct 2005), Energy Independence and Security Act 2007 (EISA 2007), GSA FY 2010-2015 Strategic Sustainability Performance Plan, and Executive Order 13693.
