I ndustrial energy demand accounts for around one third of the total energy demand whereas the largest part of this energy is for process heat Today the heat is mostly provided through the combustion of fossil fuels However a large share of this demand can be covered by solar collectors thereby reducing the fuel consumption and running costs of the business Within the last years the Emirates attracted numerous industrial companies and today almost all sectors are present aIR coNdITIoNING Especially during the summertime air conditioners are the major electricity consumer creating high peak loads and great challenges for utilities While conventional chillers run on electricity absorption chillers can convert heat to cold by making use of different thermodynamic properties of a pair of fluids The technology is readily available and well proven Moreover the heat can easily be provided by the sun as the cooling demand matches the availability of sunshine For applications process heat and solar cooling Industrial Solar offers suitable solutions PRocESS hEaT Food Industry Pasteurization Blanching Oil Chemical Industry Distillation Fermentation Pharmaceutical Industry Sterilization Granulation INdUSTRIaL SoLaR FRESNEL coLLEcToR The Fresnel Collector is a linear concentrating solar collector Uniaxial tracked mirrors concentrate the radiation on an absorber tube above the reflectors A heat transfer fluid pressurized water thermal oil steam is pumped through the absorber and delivers the heat of up to 400 C to the process The collector is optimized for industrial and commercial applications Due to a modular approach available space can be used efficiently The low weight and wind load allows installing the collectors on rooftops thereby providing shade to the building and reducing the cooling load All components are optimized to withstand harsh environmental conditions such as dust heat and humidity Industrial Solar could already prove its capabilities in various projects in the GCC ToURISm Hotels and resorts also offer interesting applications They have a high cooling demand and at the same time need heat for their domestic water and the laundry As guests demand green solutions sustainability becomes a competitive advantage The Kalba Eco tourism Project is only one among many projects highlighting the opportunities in the sector REFERENcE INSTaLLaTIoN In 2010 Industrial Solar built a collector in Doha to power an absorption chiller for a showcase football stadium The solar system has a mirror surface of 1408 m and a cooling capacity of more than 1 MW n solar EnErGy for industry and CommErCE in thE EmiratEs The Gulf countries are blessed with rich resources in oil and gas The cheap energy prices spurred the tremendous economic growth in the last years which also made the energy demand increase accordingly Today the available resources are on the decline Moreover while the international oil prices continue to rise exporting fuels is much more attractive than supplying the local market at low prices As the Gulf countries are also blessed with abundant sunshine solar energy can satisfy a large share of the local demand freeing resources for export Two major energy consumers within the Emirates are Process Heat and Cooling Industrial Solar a German solution provider for solar energy optimized its technology for these applications Martin Haagen Business Development Industrial Solar GmbH martin haagen industrial solar de FOCUS MAJLIs ISSUE 11 13
