Lüftung von Gebäuden - Kühlbalken - Prüfung und Bewertung von aktiven Kühlbalken
Diese Europäische Norm legt Verfahren zur Messung der Kühlleistung von Kühlbalken mit Zwangsbelüftung fest. Die Beurteilung der aerodynamischen Luftleistung ist nicht Bestandteil dieser Norm. Die Beurteilung der aerodynamischen Luftleistung wird in der Zukunft in einer neuen Norm mit dem Titel "Lüftung von Gebäuden — Luftdurchlässe — Strömungstechnische Prüfung und Bewertung von Mischlüftungs¬anwendungen im anisothermen Betrieb — Teil 1: Kaltluftstrahlen" behandelt.
Zweck dieser Norm ist es, vergleichbare und reproduzierbare Produktkennwerte zur Verfügung zu stellen.
Das Prüfverfahren gilt für sämtliche Bauarten von konvektiven Kühlsystemen mit Zwangsbelüftung unter Verwendung eines beliebigen Mediums als Medium für den Energietransport. Diese Norm gilt nur dann, wenn lediglich die induzierte Luft durch den Wärmeübertrager strömt (die Primärluft strömt nicht durch den Wärmeübertrager).
ANMERKUNG Das Ergebnis gilt nur für den festgelegten Prüfaufbau. Bei anderen Bedingungen (d. h. bei einer anderen Anordnung der Wärmelasten, inaktiven Deckenelementen in der Umgebung der Prüfgegenstände) sollte der Hersteller Richtlinien auf Grundlage von maßstabsgetreuen Prüfungen zur Verfügung stellen.
Diese Norm bezieht sich auf Wasser als hauptsächliches Kühlmedium, mit der Möglichkeit einer zusätzlichen Kühlung durch die Primärluft. Bei Prüfungen, für die Wasser als Kühlmedium genannt ist, kann auch jedes andere Kühlmedium verwendet werden.
Ventilation des bâtiments - Poutres froides - Essai et évaluation des poutres froides actives
La présente Norme européenne spécifie les méthodes de mesure de la puissance frigorifique des poutres froides à ventilation forcée. L'évaluation de la performance aérodynamique de l'air ne fait pas partie de la présente norme. Ceci fera l'objet d'une future norme intitulée "Unités terminales - Essais aérodynamiques et étalonnage pour applications de fluides mixtes pour les essais non-isothermes - Jets froids".
La norme vise à attribuer aux produits des données comparables et répétables.
La méthode d’essai s’applique à tous les types de systèmes de refroidissement convectif à ventilation forcée quel que soit le milieu utilisé pour véhiculer l’énergie. La présente norme ne s'applique qu'aux situations où l'air induit ne passe que par l'échangeur de chaleur (l'air primaire ne passe pas par l'échangeur de chaleur).
NOTE Le résultat n’est valable que pour l’installation d’essai spécifiée. Pour d’autres conditions (c’est-à-dire positions différentes des sources de chaleur, éléments de plafond inactifs autour des dispositifs soumis à l’essai), il y a lieu pour le fournisseur de donner des indications basées sur des essais en vraie grandeur.
Dans l’ensemble de la présente norme le fluide froid de référence est l’eau, avec la possibilité d'un refroidissement complémentaire par l'air primaire. Toutefois, chaque fois qu’il est question d’eau, tout autre fluide de refroidissement est également utilisable pour l’essai.

Overview
EN 15116:2008 (CEN) - "Ventilation in buildings - Chilled beams - Testing and rating of active chilled beams" - specifies methods for measuring the cooling capacity of active chilled beams with forced air supply. The standard defines repeatable, comparable product data by describing test-room conditions, two alternative heat-supply methods, measurement principles and result expression. It targets convector cooling systems where induced air passes only through the heat exchanger (primary air does not pass through the coil). Water is treated as the main cooling medium, although other media may be used in the prescribed test procedures.
Key topics
- Purpose: Provide comparable and repeatable product data for active chilled beams (water-side cooling capacity and specific ratings).
- Measurement principle: Water-side cooling capacity calculated from measured cooling-water flow rate and temperature rise (steady state).
- Test methods: Two allowed approaches:
- Internal heat supply method - room heated by electric dummies (person simulators) inside an insulated test room.
- External heat supply method - heat supplied via walls/floor with controlled inner-surface temperatures.
- Test-room requirements: Recommended room ~4 m × 4 m × 3 m (floor area 10–21 m²; height 2.7–3.0 m). Airtightness and controlled inner-surface temperatures are specified (limits on heat flow through surfaces and uniformity).
- Key parameters and definitions: primary/induced/exhaust air flow rates, reference air temperature, mean cooling-water temperature, temperature difference Δθ (reference air – water mean), nominal Δθ = 8 K, nominal water flow definition (2 K ± 0.2 K temperature rise).
- Result expression: Water-side cooling capacity as function of primary air flow and Δθ; specific cooling capacity per unit length, nominal capacities and uncertainty reporting.
- Limitations: Aerodynamic air performance (mixed-flow jet behavior) is excluded and addressed in a separate/new standard; test results apply only to the specified test setup - manufacturers should provide guidance or full-scale tests for other installation conditions.
Applications
- Manufacturers: product development, performance declarations and datasheets for active chilled beams.
- Testing laboratories: standardized test procedures for certification and comparative testing.
- HVAC consultants and designers: verify chilled beam cooling capacity for selection and system design, and interpret manufacturer data correctly for building simulations.
- Specifiers and building owners: compare products on a like-for-like basis when assessing cooling performance and capacity.

4 Test method
4.1 Principle
4.1.1 General
The water side cooling capacity of the test object shall be determined from measurements of the cooling
water flow rate and cooling water temperature rise under steady state condition. The water side cooling
capacity shall be presented as a function of the primary air flow rate and the temperature difference
between the reference air temperature and the mean cooling water temperature.
The measurements shall be performed in an airtight room, to the requirements of 4.2, with controlled
temperatures on the inside surfaces. Two alternative methods are allowed:
4.1.2 The internal heat supply method
The perimeter of the room shall be insulated and have negligible heat flow through it. The perimeters
shall be insulated in such a way that during the test the average heat flow through these surfaces is less
-2
than 0,40 W·m .
To balance the cooling capacity of the test object, heating is supplied in the test room by means of a
number of electric heated person simulators, dummies, as described in 4.3 of EN 14240:2004. The
dummies are placed on the floor inside the test room. To get reproducible results the dummies shall be
placed in determined positions as described in 4.4.1 of EN 14240:2004. For location of beam(s) relative
to the dummies, see 4.4.1 of this standard.
NOTE This method uses the same test room and heating supply to the room as specified in EN 14240 for
testing and rating of chilled ceilings.
4.1.3 The external heat supply method
To balance the cooling capacity of the test object, heating is supplied to the test room evenly distributed
through the walls and the floor. The ceiling shall be insulated in such a way that during the test the heat
-2
flow through the ceiling is less than 0,40 W·m . The temperature of the inner walls and floor of the test
room shall be controlled and maintained uniform at any level necessary to keep the desired room
temperature. The maximum temperature difference between any point of the inner walls and floor during
the test shall be less than 1 K.
4.2 Test room
2 2
The floor area of the test room shall be between 10 m and 21 m .
The ratio of width to length of the test room shall be not less than 0,5; and the inside height shall be
between 2,7 m and 3 m.
The recommended inside dimensions are a length of 4 m, a width of 4 m and a height of 3 m.
NOTE 1 The test room specification enables the use of test rooms in accordance with EN 442 for the testing of
chilled beams. The dimensions of the test room are given as a recommendation. It is permitted for the test room
dimensions to deviate from the recommended dimensions.
The test room shall be sufficiently tight to minimise flow from the ambient air outside which shall not
-1 -2
exceed 0,8 ls m of the perimeter surface at a pressure difference of 50 Pa (note includes floor walls and
ceiling).
The outside of the room or outer room as appropriate should be insulated. The heat loss to the outside
should be determined by preliminary calibration (without test object cooling) to demonstrate compliance
with either 4.1.2 or 4.1.3 as appropriate.
