  1. Lindab solo - Simply the natural choice...

  2. Chilled beam revolution! • Save up to 45 % cooling energy!* • Installation and investment savings! • Maintenance and running costs savings! • Win – Win situation • *Documented by SBI publication 2013 (Aalborg University, Denmark)

  3. Chilled beam revolution! • High temperature cooling and Low temperature heating! • No need for simultaneously running heating and cooling units ever again! • No regulation equipment and pipe treatment • No regulation valves • No actuators • No room regulators • No sensors (e.g. presence & CO2) • No pipe insulation • Large installation savings! • One set of pipes can be used for heating and cooling, at the same time!

  4. 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

  5. Temperature vs. loads • Expectedindoortemperature • The water flow is constant • Outdoor temperature will dictate inlet temperature • Difference in external/internal loads will affect room temperature • Spring/Autumn: • Internal + external load = -230W • Room temperature = 20°C Capacity per beam, 3,0m [W] • Summer: • Internal + external load = +600W • Room temperature = 24,4°C Summer Spring/Autumn Winter • Winter: • Internal + external load = -400W • Room temperature = 20°C Room temperature [°C]

  6. System description – Spring and Autumn • 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. • HighTemperatureCooling (HTC) and LowTemperatureHeating (LTH) North facade Heating demand South facade Coolingdemand

  7. System description - Summer • HighTemperatureCooling (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 North facade Coolingdemand South facade Coolingdemand

  8. System description - Winter • LowTemperatureHeating (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.

  10. Free cooling solution • Optimizefreecoolingopportunities • Free cooling overview: • 1: Free cooling ON/OFF (Optimized) – Save 32% energy • 2: Free cooling MODULATING (Optimized) – Save 45% energy

  11. 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.

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

  13. 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.

  14. 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.

  15. 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.

  16. Summary No regulation valves, actuators etc. Continuously running system = No need for regulation on individual beams. No need of pipe Insulation, neither on ducts. Free cooling High Temperature Cooling results in optimal conditions for free cooling. Recycled energy use SOLO is keeping the thermal energy in the building, instead of supplying and redrawing energy No radiators or pipes for heating Heating is delivered by the Solo system = No need for radiators and associative piping Better COP performance 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) Renewable energy The SOLO system allows a much better energy efficiency when using sustainable energy sources.
