WAAB 300 Active hill d b A ti chilled beam – width 300 idth The WAAB-300 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-300 chilled beam is a battery, formed by copper tubing and aluminium blades. 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-300 chilled beam can be supplied with connections on the side or on the top, for both supply air and return air. The unit can be adapted to medium panel modular ceilings with 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. Induced air The WAAB 300 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...

CONSTRUCTION AND WORKING SYSTEM Airflow adjustment The WAAB 300 chilled beam can be supplied with a primary airflow adjustment system. This system can be used to select between three different air output configurations. Thus, even if the project specifications change, the primary airflow can still be readjusted using the same installation. KL Modification of the air deflection angle. The WAAB 300 chilled beam can be supplied with air deflectors situated over the internal frame The frame. deflectors can be adjusted individually over a range of 0 to 45 º, permitting a wide variety of...

The number of brackets available varies depending on the nominal length of the selected chilled beam; 4 for LN ≤ 1800 mm and 8 for LN ≥ 2100 mm. 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...

Determining th D t i i 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. mwc Ti,wc mwh Ti,wh To,wc To,wh The following diagrams show the characteristic curves for each of the models corresponding to the WAAB 300 product.

TECHNICAL DATA and METHODOLOGY Methodology A chilled beam’s capacity consists of one part supplied by the primary air and a second part supplied by the water. P = Ppr + Pw,r The primary air rate can be calculated using the Graphs numbered with II. It can likewise be calculated using the following equation: Because of the chilled beams’ high capacity in heating mode, it is not necessary for the primary air to supply additional heat. In these cases, the system usually works with a discharge of isothermal air, that is, by discharging the primary air at the same temperature as that in the...

TECHNICAL DATA and METHODOLOGY Calculation 1.- Firstly, we determine the primary airflow volume for each of the chilled beams. Using Diagram IV on page 14, we select the type of nozzle depending on the maximum permissible noise level. Diagram IV N Di IV: Nozzle KS → mpr=75 m3/h → LWA=39 dBA → Pa = 150 P l 75 39 Pa 2.- The chilled beam’s nominal cooling capacity is determined based on the primary airflow and the difference in temperature between the benchmark for the premises and the supply water (∆twa). To do this, we use diagrams V and VI. Diagram V and VI: Nozzles KS → mpr=75 m3/h →...
