Beam description
The Lindab Solo beam
•
•
•
Powerful chilled beam battery
Great capacity at extreme low
temperature heating and high
temperature cooling
Fixed spread pattern and
factory preset air volume, for an
easy and convenient solution
Example
3,6 m Solo beam in a 25°C room
Air = 25 l/s at 100 Pa
Water = 20°C in - 23°C out
Total cooling capacity = 744W

Temperature vs. loads
Expected indoor temperature
•
•
•
The water flow is constant
Outdoor temperature will dictate inlet temperature
Difference in external/internal loads will affect room temperature
•
Capacity per beam, 3,0m [W]
•
Summer
Spring/Autumn:
Internal + external load = -230W
Room temperature = 20°C
Summer:
Internal + external load = +600W
Room temperature = 24,4°C

High Temperature Cooling (HTC) and Low Temperature Heating (LTH)
•
•
•
•
•
Needed inlet temperature reached
fully or partially by mixing the return
water .
Allows for fully or partially shut down
of heating and cooling units
Savings of up to 5 % on total energy
usage (without free cooling).
Either the heating or cooling unit
needs to be running. But not both at
the same time.
Should assistance from the cooling
unit be necessary, free cooling should
be obtainable through part of the
season.

High Temperature Cooling (HTC)
•
•
•
•
•
•
Cooling supplied via beams running
relatively high temperature water
Possible due to the optimized high
output battery, unique the Solo
beam.
Offers great possibilities for free
cooling
25 % better COP from cooling units
Extremely low risk of condensation,
due to the high inlet temperature.
As heating demands may occur
during Summer in some regions,
even higher savings can be expected

LowTemperature Heating (LTH)
•
•
•
•
•
Lower water temperatures
compared to conventional radiator
or chill beam systems.
Possible due to the optimized high
output battery, unique to the Solo
beam.
Smaller risk of heat loss from
pipes, as running temperature is
close to room temperature.
Eliminate problems with draft, due
to near-isothermal inlet
temperatures.
Low temperature stratification in
the occupied zone results in a
better mix of room and inlet air.

Better COP performance
Optimized cooling and heating performance
•
Cooling & Heating unit performance
Higher cooling temperatures in the Solo system,
allows for a more efficient use of heat pumps.
•
Coefficient Of Performance (COP)
The Δt between the outdoor temperature
and the inlet water temperature in cooling
scenarios will normally be at least 5°C lower
on the Solo solution than on conventional
systems.
The COP value of the heat pump can
therefore be expected to be over 25% higher
than in a conventional system.
The Δt value in heating scenarios is even
better, giving even larger savings when
using a heat pump for both cooling and
heating.

Renewable energy
Solo – optimizing substainable energy usage
•
•
Low heating water temperatures optimal for solar
panels.
Geothermal heating, heat pumps and other low
temperature energy sources are suitable as well.

Installation and investment savings
Savings, on several aspects
•
Installation time
A simple solution enables a quicker
installation, providing further savings
•
Overall savings
The simplicity of the Solo system
means less accessories. Which in turn
means huge savings, especially as
radiators are not needed.
lindab | comfort
Maintenance and running costs savings
Future savings
•
Cooling energy consumption
Lower running times on cooling units, plus
the use of free cooling, provides a huge
saving potential.
•
Maintenance
Less components gives a much lower
maintenance cost.

Heating and Cooling sources
Points of interest
•
•
•
Heat pumps
• Better COP, due to
temperature set
• Applicable for both heating and
cooling
•
•
District heating from heat plant
• Lower running temperatures on
the Solo system offers a lower
return temperature to the heat
plant
District cooling from cooling plant
• New way of cooling
• Applicable to Lindab Solo
Free cooling
• Better gain, and longer season,
due to temperature set
• Both heating and cooling
Solar panels
• Low inlet temperature for
heating, enables the full use of
solar panels in spring/autumn.

Summary
No regulation valves, actuators etc.
Free cooling
Continuously running system =
No need for regulation on individual beams.
No need of pipe Insulation, neither on ducts.
High Temperature Cooling results in
optimal conditions for free cooling.
No radiators or pipes for heating
Recycled energy use
Heating is delivered by the Solo system =
No need for radiators and associative piping
SOLO is keeping the thermal energy
in the building, instead of supplying
and redrawing energy
Better COP performance
Renewable energy
The cooling water temperature in SOLO is at
least 5 degrees higher compared to
conventional chilled beam systems =
Increased COP of >25% for the cooling unit
(Higher COP for heating unit as well)
The SOLO system allows a much
better energy efficiency when using
sustainable energy sources.
