Frenger - 20 Years of Multi Service Chilled Beam Solutions

Chilled Beam Technology - 55 Baker Street - MSCB Units

Frenger Multi Service Chilled Beams

Frenger supplied & installed the world’s largest Chilled Ceiling (175,000m²) at the Shell Building in 1962.

Nowadays Frenger Systems manufacture Chilled Beam Technology and supplied & installed the world’s largest Multi Service Chilled Beam (MSCB) project in 2007 (4,500 MSCB units) at 55 Baker Street.

MSCB units can utilise either passive or active beam technologies. They provide visually stunning yet 100% functional building services which are 100% pre-fabricated off site in a controlled factory environment, thus significantly reducing the site installation programme. All services are 100% factory tested and delivered ‘Plug n Play’ to reduce on-site commissioning time.

Key Benefits

  • Ideal where floor-to-slab height is minimal
  • Low running costs - minimal maintenance requirements
  • Delivers many services in a single unit - so reducing costs
  • Optimum levels of occupancy thermal comfort
  • Beam aesthetic can be customised to client requirements

Design Options

The following building services can be integrated within Frenger MSCB’s:

  • Cooling
  • Up-lighting
  • Control valves
  • Smoke detectors
  • Fresh Air
  • Heating
  • Direct lighting
  • Sprinklers
  • Lighting sensors
  • PA / VA Speakers
  • Electrical Compartmentation
  • Emergency Lighting
  • Acoustic insulation
  • Distribution Ductwork
  • Distribution water pipes

Frenger Chilled Beam SystemThere are several aspects of a “Chilled Beam System” that promotes a more energy efficient operation than other air based HVAC solutions.

Chilled water is distributed to the chilled beams above dew point, typically at 14-17°C to avoid the risk of condensation, whereas other HVAC solutions operate below dew point, typically at 6-12°C.

Elevated chilled water temperatures (i.e. above dew point) offer two principal benefits in terms of energy efficiency:

  • By operating the chiller plant at elevated temperatures, its co-efficient of performance (COP) is increased & energy consumption reduced. The efficiency of the compressor can be increased by using a dry cooling system (inlet water 14°C instead of 7°C) with a percentage increase in COP of typically 22%.
  • Elevated temperatures enable a significant increase in the opportunity to avail free cooling from sources such as outdoor air or ground water heat sinks. That is an annual increase from 800 hours to 2000 hours for a 12 hour day & 2100 to 5200 hours for 24 hour operation.

Fan coil units and VAV systems rely on a fan assisted cooling distribution; that is each fan coil unit incorporates a fan. Active Chilled Beam systems utilise a centralised fan that delivers just enough air to meet respiratory requirements (or a little more in the case of some active chilled beam systems) with a consequent reduction in capital cost, electricity consumption and maintenance cost.
