2 Topics 1. Introduction Industrial Solar 2. Technologies: Air collector and Fresnel collector 3. Overview Technologies & Solutions

3 Company Overview History Industrial Solar is a leading solution provider for energy projects with references around the world. It was founded in 2008 in the environment of the renown Fraunhofer Institute for Solar Energy Systems (ISE) to realize solar thermal projects based on its innovative Fresnel collector. Today Today Industrial Solar is the world leader in Fresnel projects for industrial energy supply and delivers comprehensive and customized energy solutions based on different technologies. Group Industrial Solar GmbH is group member of CENTROTEC Sustainable AG. CENTROTEC is listed holding at the Frankfurt stock exchange and has specialized in energy-efficient technologies. It is represented in over 50 countries. In 2014 its group revenue reached 530 Mio and the number of employees was about Mission Based on a comprehensive analysis we identify, design and implement the most economic renewable energy technology onsite

5 Approach Energy Monitoring Energy Analysis Energy Conservation Energy Efficiency Renewable Energy

6 Sun-Storm Air Collectors

7 Function Double glass tube With vacuum Air-distribution unit Cold Air Hot Air

8 Why Air? Simple and safe installation Air does not freeze Air is for free Leakages do not cause structural damage through hot liquids No stagnation problems even with large collector fields No degradation of the solar fluids No venting problems No redundant pumps No expensive safety installations Safe large-scale systems, exceeding 1000 m² possible > simple + safe + highly efficient

9 Basic Easy System Principle Heat output depends on Irradiaton / sun hours Collector orientation Interconnection to systems for Heating Air handling/drying Industrial Processes Solar cooling to reduce Fossil heat consumption Carbon emissions Reduction depends on Operation time Operation temperature Stagnation times

11 Characteristics of Sun-Storm Collector For an efficient use of solar energy the Sun-Storm air-collector consists of evacuated tubes. An evacuated tube consists of two glass tubes. The tubes are connected on one side and are closed at the other. It is similar to how a coffee thermos is assembled. There is a vacuum in between the glass tubes. The good isolation characteristics of the vacuum allow only very little heat to be released into the environment. With 45 C, the evacuated tube can be touched on the outside, while the inside temperature can reach up to 230 C. This special characteristic is also beneficial in winter, because of the good isolation, a temperature of about 100 C can still be reached inside the "Sun-Storm"- collector, even if the outside temperature is very low. Inside every absorber (heat collecting field in the middle of an evacuated tube) is a thin walled aluminum-injection tube which makes sure that the air inside the solar air collector is distributed optimally, thus a safe and highly efficient heat transfer can be assured.

12 Sun-Storm Advantages Air-collector with vacuum tubes High temperature spread Air applications without transfer losses Simple system solutions LA-Box to heat up fluids

13 Diversity of Sun Storm Variants Different box (header) lengths: 1958 mm= 50 Evacuated tubes 1208 mm= 30 Evacuated tubes 458 mm = 10 Evacuated tubes Different evacuated tube lengths: 2100 mm 1500 mm 1000 mm 500 mm For example, different lengths allow the bypassing of roof windows in the collector fields.

14 Integration steps 1. Process analysis 2. System configuration 3. Simulation Engineering 4. Economic Analysis 5. Installation of Sun-Storm-Collectors 6. Commissioning 7. Monitoring

15 Applications Examples for processes which need hot air directly: Air pre-heating in air conditioning systems Air space heating for gymnasiums Drying processes e.g. sorption materials (drying materials), wood or groceries Air space heating e.g. for industrial or apartment house Hot air for paint shops Solar cooling systems with open air loops (DEC-systems)

16 Sun Storm s High Efficiency

17 Excurse: Stagnation Stagnation at flatplate and vacuum tube collectors: Heat is not used Collector heats up until stagnation temperature is reached Extremly high thermal treatment of heat transfer fluid and collector material If stagnation cannot be controlled system will collapse and damage occure > stagnation risk & damages If the "Sun-Storm"-collector is connected to an air-water-heat-exchanger, liquids can be heated up to over 120 C. Through the usage of air in the collector loop, the system can be started up during a stagnation period (phase, where no heat is taken out of the system by the consumer). Temperatures of over 230 C do not pose a problem for the system. > No stagnation risk & damages

18 Example: Air-water-heat systems Examples for processes with air-water-heat-exchangers: Domestic and industrial water heating and heating support, as well as housing construction Solar cooling and solar industrial processes: Cooling in summer and heating in winter Typical applications are: Superior residentials with high solar fraction Car dealers Supermarkets Hotels Exhibition halls Schools Swimming pools Office buildings etc.
