Scope of the programme

The Eurovent Certification programme for Chilled Beams applies to all Active and Passive Chilled Beams of the Applicant/Participant.

Chilled ceilings Radiant Heating panels are excluded.

Certify-all: Chilled Beams are presented by ranges and all ranges must be certified. This applies to all product ranges which have either catalogue leaflets with product details including technical data or similar product information in electronic format. ECC certifies the performances of the ranges as presented in their selection tool.
Definitions

Passive Chilled Beam

Convector cooled with water or any other liquid and mounted under the ceiling or integrated into a false ceiling.

Active Chilled Beam

Convector with integrated air supply where the induced air or primary air plus induced air pass through the cooling coil cooled with water or any other liquid.

Range

In order to be considered in the same range (in the certification process), the models must have some fixed characteristics, while all others may be variable.

The basic element of an active chilled beam is a coil and the following characteristics shall be fixed:

  • Coil width
  • Coil height
  • Fin material, surface and spacing
  • Pipe material, shape (internally smooth or rifled) and pattern
  • Plenum and diffuser geometry
  • Discharge (one way, two ways, three ways and four ways)
  • Range name (commercial name)

Other characteristics may differ between products in the same range, such as:

  • Coil length
  • Pipe connections
  • Nozzle configuration
  • Pipe diameter
  • With/without heating

For passive beams, the following characteristics shall be fixed:

  • Coil height
  • Fin material, surface and spacing
  • Pipe material, shape (internally smooth or rifled) and pattern
  • Range name (commercial name)

Other characteristics may differ between models in the same range, such as:

  • Coil length
  • Coil width
  • Casing depth below coil
  • Open discharge or perforation
Testing Requirements

Standard ratings shall be established at the standard conditions specified in the relevant test standards. Standard ratings shall be verified by tests conducted by the ECC independent laboratory in accordance with the following standards:

  • EN 15116:2008 - "Testing and rating of Active Chilled Beams"
  • EN 14518:2005 - "Testing and rating of Passive Chilled Beams".
If vanes can be oriented, the laboratory shall test the unit in the straight configuration or with the smallest angle (most favorable configuration for the capacity). Openings of the DIN dummies shall be covered when testing passive and active beams.
Rating requirements

I.1       Mounting of passive chilled beams

Passive beam shall be mounted under a ceiling.

Active beams are usually mounted under the ceiling or integrated into a false ceiling but they may have other mountings: on the floor, on the wall, etc.

I.2       Pressure testing and correction for water cooling capacity

One air pressure (static chamber pressure or total pressure loss of the unit) has to be provided in the documentation/software by the Applicant/Participant for the capacity to be rated.

 The test shall be performed for nominal primary airflow rate. The measured pressure drop Δp shall be within ± 10% of claimed value. If Δp may be adjusted, the manufacturer is allowed to do it.

In all cases, the capacity shall be corrected, following the formula:

                                                           Pc=Pm*√(Δpn/Δpm)

with:

Pc          =   Pressure corrected water cooling capacity

Pm         =   Measured water cooling capacity

Δpn        =   Chamber pressure or total pressure loss given in manufacturer's documentation

Δpm       =   Pressure recorded during the measurement from the product's measurement connection or static pressure measured using 4 static taps connected by piezometric ring.

Formula used on the nominal airflow rate, and the same correction factor is used for 80% and 120%. In the reports, the laboratory shall give the claimed, the measured values and corrected output of the formula.

The corrected value Pc shall be compared with the claimed value.

Certified characteristics

The following performance shall be certified and verified by tests:

  • For Passive Beams:
    • Cooling capacity in compliance with the requirements of EN14518, including testing with three values of Δθ.
    • Water pressure drop.
  • For Active Beams:
    • Cooling capacity in compliance with the requirements of EN15116 - three values of air flow rate (nominal air flow rate, 80 and 120% of the nominal air flow rate), for the nominal temperature difference (8K) only for the nominal water flow rate.
    • Water pressure drop.
