WAAB 4-WAY Active chilled beam with 4-way The WAAB 4-WAY chilled beam is an air/water induction terminal unit that simultaneously provides the supply, thermal treatment and diffusion of supply air, to set internal conditions at the desired comfort levels. Chilled beams take advantage of the excellent thermal properties of water to guarantee optimal comfort levels, with minimal power consumption. The main heat-transferring component in the WAAB 4-WAY chilled beam is a battery, formed by copper tubing and aluminium fins. It also incorporates air ducts and a plenum for supplying the ventilation air, which has been pre-treated in a central air conditioning unit. The WAAB 4-WAY chilled beam can be supplied with connections on the side or on the top for supply air. The unit can be adapted to modular ceilings measuring 600x600, 625x625 and 675x675 for T24 and T15 profiles. Thanks to its reduced size, it can also be installed in low-hanging false ceilings.

CONSTRUCTION AND WORKING SYSTEM The ventilation air is injected through nozzles that cause the air to accelerate and force air induction in the room, through the battery. Subsequently, the two masses of air (the induced air and ventilation air) are supplied to the space that requires air-conditioning. The WAAB 4-WAY has been designed so that it can be accessed easily for maintenance and servicing operations. For this, it has 4 fastening clips, which keep the internal frame in position. Access the clips and move them to release the internal frame, which can then be extracted. Once the...

CONSTRUCTION AND WORKING SYSTEM Airflow adjustment The WAAB 4-WAY chilled beam can be supplied with a primary airflow adjustment system. This adjustment can be made using a tube wrench with a diameter of 8 mm, making it easy to select between three air output configurations. Thus, even if the project specifications change, the primary airflow can still be readjusted using the same installation. Modification of the air deflection angle. The WAAB 4-WAY chilled beam can be supplied with air deflectors situated over the internal frame. The deflectors can be adjusted individually over a range of...

The WAAB 4-WAYS chilled beam incorporates a series of mounting slots on both sides. These slots have a length of 20-mm, so that the chilled beam can be easily mounted in the installation. The unit should be suspended from the structure with officially approved steel supports, cables or rods. Once suspended, the primary air duct should be connected to the plenum’s neck. Likewise, the battery should be connected with solid elements, welding or quick connect fittings. Check that the hydraulic circuit has been properly emptied and that the beam is properly connected to the ventilation system to...

DEFINITIONS WAAB 4-WAY Determining the performance/characteristics of chilled beams properly requires the performance of both thermal and diffusion tests, based on the benchmarks of standards EN 15116, EN 13182 and EN 14240. For technical product selection uses software selection MADEL: http://www.madel.com/en/downloads -en/ The benchmark is as follows: Longitud nominal (1) The recommended flow volume will maintain a thermal gradient of 3-4 °C in the battery. (2) We recommend using a supply water temperature of 14-16 °C to avoid condensation. (3) We recommend using a supply water...
