iQ Star - Stella

Energy efficient multi-service chilled beam



tella is our exposed multi-service Chilled Beam in the new iQ Star family.

It is characterised by modularity, flexibility, sustainability and energy efficiency.

Stella is developed specifically for the high demands of the modern, dynamic

office where an aesthetic design is equally important to cutting-edge energy

saving features. Thanks to pioneering nozzle technology and smart controls,

the air flow is always sufficient and adapted to suit requirements.

The aluminium profiled Stella incorporates an array of integrated features. Stella’s

modularity, Flow Pattern Control, Comfort Control and smart control functions allow

greater flexibility within the office layout without compromising indoor air quality.

Boost, Normal or Energy Saving mode

The notion of the traditional office being fully occupied from 9 to 5 is fast becoming a

distant memory. With varying occupancy levels Stella’s smart control panel with Energy

Saving, Normal and Boost modes enables easy adjustment of the air flow. This means

that whether an office or meeting room is empty or crowded, the Stella beam provides

sufficient air flow. Not only does it save energy when the room is not in use, it also keeps

the employees healthy and alert during high occupancy. Stella - An excellent means of

delivering high indoor air quality.

Flow Pattern ControlThe unique Flow Pattern Control (FPC) can direct the airflow up to 45 degrees through integrated vanes. Different directions can be set in 300mm sections within discharge slot.

Flexible, comfortable and energy efficient climate for the modern office

S StellaEnergy Control

Pioneering variable position nozzle

technology guarantees both high

indoor air quality and energy efficiency.

AccessoriesThe iQ stella incorporates an array of integrated features ranging from direct/indirect lighting with either satin louvred or the new prismatic diffuser options, PIR’s, smoke detectors, speakers and sprinklers.



The STRA-14 room controller is

specifically developed for Stella.

It is pre-programmed for chilled beam

applications and contains a wide range

of control functions including a uniquethree step air flow control for flexibility,

comfort and energy efficiency.

The user-friendly display enables

fast and easy access for change of

set-points and control parameters.

For optional integration with building

management systems, STRA-14

has Modbus communication as

standard.

For rooms with variations in occupancy,

the following control strategy can be

adopted using an occupancy sensor.

Energy Saving Mode (reduced air

flow and increased neutral zone for

heating and cooling) when the room

is unoccupied and thereby energy is

saved.

Normal Mode, when the occupancy

sensor is activated by presence in the

room airflow, heating and cooling is

adjusted for comfort levels.

Experience has shown that the

level of CO2

in a room is a reliable

indicator of the indoor air quality, and

is therefore used as the determining

parameter in the integrated Energy

Control in Stella. A high level of CO2

in a room indicates that the ventilation

rate is insufficient to obtain an

adequate indoor quality.

This is a common situation in rooms

with large variations or peaks in

usage, therefore STRA-14 can be

equipped with an optional CO2

sensor

and thereby offer a control functionwhere the controller shifts to Boost

Mode if the level of CO2

exceeds

the set point value. In this mode the

integrated Energy Control opens and

the air flow is increased until the level

of CO2

has decreased to the lower set

point value.

The manual override switch on

STRA-14 can also be used to activate

the bypass mode, after 60 minutes

the controller then changes back to

its preset operating mode.

Increased productivity and low energy costs

Demand Controlled Ventilation

Today, most people spend over 90

percent of their time indoors e.g.at home, in schools, at hospitals or

offices. Breathing fresh indoor air is

vital for our health, performance and

well-being.

Demand controlled ventilation provides desired

ventilation based on the actual occupancy of the room.

It increases indoor air quality and saves energy normally

wasted in ventilating unoccupied spaces. This can be

applied to areas where there are frequent changes inoccupancy, such as conference rooms, board rooms,

cafeterias etc.

Offices are designed for 100% occupancy - field

experience indicates that actual occupancy levels in

offices are at least 25% lower and perhaps as much

as 60% lower. This means that demand controlled

ventilation can reduce volume flow rate as well as heating

and cooling loads.

User-friendly controller for optimal performance

Pioneering nozzles

Stella always provides the correct

air flow, whether the room is empty

or crowded. With the option of

Energy Saving, Normal or Boost

mode. The new variable nozzlearrangement can respond to

occupancy, providing high indoor air

quality and energy efficiency.

A quiet solution even when high

air flow is needed.

Flexible solutions for your changing needs

IQ Star Chilled Beams

with FPC function

Highest possible efficiency can

be maintained by adjusting the

air vanes for comfort.

A combination of different

angles on one side is possible.

When increased air flow isrequired, the flow pattern

can be adapted to maintain

optimal comfort in the room.

The modern office is dynamic. Fast decisions

in organisational changes call for a modern

ventilation system that is easy to adjust to the

rearrangement of people, walls and furniture

and to meet requirements. Flexibility is an

important factor for optimised indoor air

quality and indoor air control.

Flexibility in the office layout

Good indoor air quality is possible despite

organisational changes and renovations

without the need to change the installation.

with Energy Control and Flow Pattern

Control, the air flow can be altered to fit a

new layout of a room.

Customise your own design

Aesthetic impact is important in Interior design -

Stella offers a default design with the opportunity of

adapting profiles to architectural themes. Aesthetic

Flexibility achieves the impact you desire.
