Frenger’s calculation programme for Eco is extremely user
friendly.

Simply select from the drop down menu the “Beam Variant”
and “Air Connection” configuration. Air volumes in excess of
40 ltrs / sec and up to 50 ltrs / sec should be 2 x 80 diameter.

“Manifold Types” can be changed in the drop down menu for
increased waterside cooling effect, however attention needs
to be taken regarding resultant pressure drops (hydraulic
resistance), if pressure drops need reducing, choose a higher
numbered manifold (C5 being the highest and C2 being the
lowest).

Active Chilled Beam Calculation Tool version 1.3.1 “Discharge Throw” can be S (short), M (medium) or L (long).
Is this the latest version?

they can free up ceiling area whilst still handling significant
heat gains and heat losses. However, the challenge has been
to meet these demands whilst still delivering high levels of
occupancy comfort. Frenger's Halo active chilled beam meets
these challenges with its unique 360° air discharge
characteristics with concealed air discharge veins.

The lastest-generation of 360°Active Chille Beam combines
cooling and optional heating function with revolutionary air
discharge system and pattern. By introducing the air with set
back air deflector veins further up into the point of discharge
rather than being mounted on the underplates like earlier
models, this not only improves the 360° diffusion pattern it also
vastly improves the products aesthetics. This latest
development is a Registered Design in addition to the Patent
pending performance enhancing items by Frenger. When
compared to traditional 2-way or 4-way discharge pattern by
others, Halo can deliver a reduction in air velocities of up to
35%.

This optimal method of spreading the air in all directions
means the shortest possible air throws are created, resulting in
optimal levels of comfort to building occupants.

Construction

Halo is offered in 3 standard models; "I", "C" and "F". Halo Active Chilled Beam 1200 x 600 Module.

Halo "I" models are for integrated ceiling installations in
standard 15 or 24mm exposed tee bar grids (Lay-In grid
systems) replacing 600 x 600mm or 1200 x 600mm tile
modules and can be used for integration with either "mineral
fibre" tiles or plaster board ceilings.

Halo "C" - 60 and Halo "C" - 120 are designed for integration
into metal clip-in ceiling systems.

Halo "F" - 60 is designed for free-hanging exposed
applications. This is a standard model with an additional
factory fitted architectural frame enhancement kit that can be
finished in white to match the Halo beam, or provided as a
different colour to make a feature of the extruded aluminium
outer frame.

Optimum Diffusion Pattern Halo Active Chilled Beam 1200 x 600 Module fitted with architectural
frame enhancement kit.
In addition to the flexibility offered by a modular designed small
unit, Halo has been designed to deliver the most comfortable
environment at any given air volume. Traditional Active Chilled
Beams with a 1-way or 2-way throw have the potential to
throw air at high velocities over long distances, however this
may result in low comfort levels - particularly where the air
streams from adjacent beams meet and fall downwards into
the occupied zone or where beams are located close to walls
or partitions.

Beams with a 4-way throw help to alleviate this problem,
however Frenger's Halo beam takes the conecpt to the next
level with is "true" 360° diffusion pattern.

The substaintially shorter air discharge throws (35%) offered
by Halo can enable more chilled beams to be positioned into a
given room space for higher total heat gains to be offset whilst
still avoiding draughts and providing a comfortable
environment, compliant to BS EN ISO 7730.

Formula for air cooling effect: P = m x Cp x ∆t
Where:
m = mass flow [kg/s]
Cp = specific heat capacity [J/(kg-K)]
qp = air flow [l/s]
∆t = the difference between the temperature of the room and
the temperature of the supply air [K].

Multiservice Chilled Beams

Frenger manufactures and supplies Multiservice Chilled Active MSCB
Beams (MSCBs). These integrated building services units Radiant Passive MSCB
provide flexible space conditioning that can be tailored in terms Radiant Passive MSCB
of appearance and the services provided, in order to meet Active MSCB
project specific requirements. In this way they help to create
attractive, comfortable and productive working environments.

Flexible building service units

A full range of building services can be incorporated within
a Frenger multiservice chilled beam, including:


Cooling & heating.
Fresh air supply.
Uplighting, downlighting and emergency lighting.
BMS sensors, control valves & condensation detectors.
Accommodate fire alarms and sprinkler systems.
Acoustic insulation.
Pipework, ductwork & compartmental trunking.
Accommodate PA and VA speaker systems.

Bringing several services together in an integrated MSCB
unit means that the physical dimensions of the unit can
be optimised to enable use in spaces where the
floor-to-slab height is minimal. The concept also provides
the specifier with a single source of responsibility for the
design, supply and integration of all services “pre
fabricated” offsite in a controlled environment, reducing
costs and on-site time.

Operation

MSCB’s can utilise either “Radiant” Passive or Active chilled
beam technologies. The cooling units are integrated into
perforated architectural casings with either central or
side-mounted lighting. Lighting options are varied and could be
direct, indirect, a combination direct and indirect,T5
fluorescent, LED’s or continuos extruded lighting optics of
any shape and size to suit the architectural aspirations of the
project. Completed MSCB’s are factory tested and delivered to
site for “plug and play” mechanical and electrical connection /
installation.

Frenger’s passive MSCB utilise the company’s “Radiant”/
Convective products to provide comfortable cooling through a
combination of convective and radiant heat transfer processes;
warm room air is cooled through contact with the chilled beam
and diffused into the space through the perforated underplate,
the beam casing is also cooled via secondary radiation and
thus absorbing heat from the warmer occupants. This type of
passive cooling provides the best possible combination of high
cooling capacities and exception levels of occupancy comfort
with minimal maintenance.

Where there is a need to use the MSCB to deliver fresh
air into the space, then Frenger’s Slim Line or High Output
Active beam products will form the basis for the company’s
active MSCB’s. Active beams utilise the delivery of supply air
to induce warmer room air through the unit’s cooling battery.
The technology employed in Frenger’s active chilled beams

ensures high cooling capacity with low supply air volumes,

coupled with a quiet and controlled delivery of air for optimal
comfort.

Both types of MSCB are designed for simple installation;
electrical, water and air connections can be inter-linked
from unit to unit by simple “Plug and Play” connections
to reduce on-site time to a minimum.

84

Finish and appearance

MSCB’s offer an alternative to the monolithic ceilings that
have become commonplace in office developments, providing
attractive yet functional building services installations. The
appearance of each beam can be customised in terms of
shape, dimensions, lighting options, colour and perforation
pattern to meet the client’s particular requirements.

Technical Support

Frenger can draw upon many years experience in the Active MSCB
design and manufacture of cooling systems which combine
the highest levels of occupancy comfort with class-leading
design. Frenger has inhouse specialist manufacturing,

Chilled Ceilings - First Generation

Introduction & Overview
Technical Advancements of Chilled Ceilings

Static cooling systems (chilled ceilings) have, over the past 40
years, proven themselves capable of delivering high levels of
occupancy comfort at reduced running costs. Frenger
designed, supplied and installed the “World’s Largest
Radiant Chilled Ceiling” system in 1962; the 175,000
square meter, 27 stories high, Shell Oil headquarters,
situated on the river Thames in London. This building was
also the first fully sealed air conditioned building in Europe and
was revolutionary at its time as this Frenger Chilled Ceiling
used the River Thames water to cool the building
down. This was achieved by pumping in cool water from
upstream to a secondary heat exchanger which in turn cooled
(took heat out of the building by “Radiant” absorption) the
building down, then depositing the warmer return water from
the secondary heat exchanger down stream. This installation
is still operating after nearly 50 years and is a testament
to the integrity of the product and to Frenger’s design
capabilities.

Since this time the cooling requirements for a typical office Shell Oil HQ, River Thames
environment have increased considerably; higher occupancy
densities and a much higher usage of IT equipment have all
fueled this increase. It became apparent in the mid 1990’s
that the cooling capacity of a traditional chilled ceiling was not
sufficient to meet these increased heat-gains, and
consequently higher-capacity passive chilled beam fin coil
batteries were introduced into perimeter zones to offset the
solar load generated at the building façade.

Although fin coil batteries provided the extra cooling at lower
cost in £ / watt than the traditional radiant chilled ceiling, the
perimeter aesthetics suffered due to the fin coil batteries
requiring large size perforations and percentage open area
to allow air (“convection”) to circulate and this also reduced
occupancy comfort, due to higher air velocities.

Frenger however saw the opportunity to take all the benefits Traditional Radiant Chilled Ceiling
from a traditional radiant chilled ceiling for radiant cooling,
and to develop a “hybrid” product solution that also has the
cooling performance of convective only passive beams. The
hybrid retained a 40% “Radiant cooling” quotient to yield
similar aesthetics as associated with the traditional Radiant
Chilled Ceilings, also with low air velocities (for compliance
to ISO 7730 European Standard for “Indoor Air Comfort
Conditions”) and a 60% convection element for high
output cooling. Frenger’s “hybrid” Radiant / Convective Chilled
Beams are detailed on pages 13 and 14.

These attractive high quality ceiling systems provide the best
in occupancy comfort given their high “Radiant” quotient.
Approximately 70% of the total cooling is by radiant
absorption and the remaining 30% by convection if the
back of the tiles are insulated, and circa 55% Radiation
and 45% Convection if the cooling tiles are un-insulated.

“Hybrid” Radiant / Convective Chilled Beam Ceiling

86

The cooling tiles are constructed from zinc coated steel which
is polyester powder coated to whatever the project colour
requirements are.

Aluminium extruded heat exchange “pipeseats” are Mega “chilled tile”
powder coated black and are bonded to the back of the
perforated metal tile. The tiles can be any size and as large as
1.35m x 1.35m, these are known as “Mega Tiles”. The
tiles are usually insulated with black tissue faced mineral
wool pads with a class ‘O’ foil backing for increased “Radiant”
component (70% Radiation / 30% Convection).

Typically the cooling effect is 80 W/m² of activated chilled
ceiling tiles if insulated and 90 W/m² of activated chilled
ceiling tiles is possible if the ceiling tiles are un-insulated,
however the Radiant component reduces to approximately
55% and the rest of the cooling is by 45% Convection-element
when the tiles are un-insulated.

The above listed cooling effects are based on 8.5ºC
difference between “mean water temperature” (MWT)
and the “design room temperature”, known as dT(k).

Ordinarily, the ceiling grid (Tartan Grid as shown in the picture Tartan Grid Ceiling
to the right) can represent circa 20% of the overall ceiling if the
grid was 1.5m x 1.5m and each plain grid was 150mm wide.
An allowance of approximately 8% of the total ceiling area
being taken up by light fittings should also be taken into
consideration when calculating the net cooling effect on the
floor area below the traditional type chilled ceiling. The rule
of thumb is that circa 72% of the total ceiling area (room size)
is to be activated by cooling coils. As such 80 watts / m²
usually netts out at 57.6 watts / m² on the floor (insulated
tiles) and 90 watts / m² nets out at 64.8 watts / m² on the floor

Should more of the ceiling be required to be activated this is
usually achieved by the use of lay-in chilled tiles on an
exposed grid, as detailed in the picture opposite.

These solutions are both energy efficient and very low

which is the best form of cooling possible.

Radiant Heating

Radiant Heating Principles

Radiant heating is a highly effective method of heating a
room. Radiant ceiling panels heat all of the rooms surfaces
(walls, floor, desks etc...), which in turn heat up the air within
the room. Radiant panels also provide heat directly to the
occupants. Consequently, radiant heating affords an extremely
comfortable indoor environment, where there is little risk of
the person feeling too cold under the table or too hot on the
head given the surface temperature of the panels.
Furthermore, radiant heating focuses on the areas where
heating is most required - the coolest items in the room
(usually the external walls and windows). Unlike convective
heating, an increase in ceiling height does not significantly
increase the amount of heat required, hence radiant heat is
perfect for large open areas with alot of air volume.

Radiant ceiling heating systems function in virtually all types of
buildings, from busy office environments, large warehouses,
large hospitals to small day-care centres. The system can
be easily modified to suit changes to the wall or floor layout
making it an extremely flexible heating solution.

Function

With an output of 550 W / m² at 55 dtK. Modula is one of the
most efficient smooth-daced radiant heating panels currently
available.

The secret to Modula’s outstanding performance lies in its
unique method of expanding the water-carrying copper pipes
within the heat radiating aluminium extrusions. The extrusions
are then mechanically bonded to the aluminium panel face
using a heat transfer adhesive. Due to the high metal-to-metal
contact between the copper waterways and extrusions and the
fact that the aluminium pipe seats are fully bonded to the panel
face, the energy transport between the pipe and panel face is
extremely efficient.

The manufacture of Modula is semi-automated in our
purpose-built facility; consequently panels can be produced to
very high tolerances. Furthermore, the processes employed
and the standardised design means that the cost of Modula
remains highly competitive.

Modula is so simple to install that it is most often fitted by the
ceiling installer. Frenger can offer an installation service using
our own engineers or on-site training to ensure that the
installation is carried out to the very highest standard.

Design

Dimensions: Modula is available in two widths, as standard
- 0.6m and 0.3m. The dimensions are reduced (minus 8mm
on length and width) so that panels can be integrated within
a tradtitional suspended ceiling using exposed T-bars (24mm
wide) on a 600 x 600mm grid module. The depth of the
Modula panel is just 45mm.

Lengths: Modula is produced in module lengths of 0.6m, 1.2m,
1.8m, 2.4m and 3.0m as standard; non-standard lengths are
available upon request.

Water connection: Modula is available with three different
manifold types depending on the coupling arrangement and
the required water mass flow rate (10, 12, 15). The flow and
return copper pipe tails are always 15mm OD. This is to allow
the pressure drop to be optimised with different length
alternatives.

Surface finish: Modula is polyester coated as standard in RAL
9010, gloss value 20%, emissivity 0.94.

Insulation: Modula is supplied with integrated 25mm thich
45 kg / m³ class ‘O’ foil wrapped mineral wool insulation within
the panels returned flanges.

Application

Modula is particularly suited for use in hospitals, schools,
shops and offices; in fact wherever there is a need for a
high-output radiant heating panel which is simple to install,
easy to keep clean and comes at a very competitive price.
Modula is the perfect solution for integration with an exposed
grid ceiling system, but is equally suited to free hanging
applications. The panel can also be adapted to suit surface
mounted applications.
