La certificazione parte terza

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

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.
