AVL List GmbH With more than 11,500 employees, AVL L List t GmbH bH is the world's largest independent company for the development, simulation and testing of all types of powertrain systems (hybrid, combustion Parkgarage 1500 m² engine, transmission, electric drive, batteries, fuel cell and control technology), their integration into the vehicle and is increasingly taking on new tasks in the field of assisted and autonomous driving as well as data intelligence. Our ur Vision ion and Mission ion Clean. Affordable. Connected. Intelligent. We as AVL provide leading technologies and superior services to our customers to create a better world by driving mobility trends of tomorrow.
Solar project Phase I Targe rgets ts • Reducing consumption of Heat Parkgarage sourcing from Natural Gas at cost 1500 m² below district heating • Having a roof on the parking garage preventing snow and heat impact • Need for Storage tank to balance solar energy between supply and demand
Solution • The 1584 m² solar thermal plant provides heat for conditioning regulators and building’s heating systems • ESCO- Investor Solar.Nahwaerme.- energiecontracting GmbH • Installed capacity: 1100 kW nominal • Solar yield: 550 MWh/year • Ca. 240t of CO2 savings per year. • Commissioning: 2017
Benefits Phase I • Reducing consumption of Heat sourcing from Natural Gas at cost below district heating • Having a roof on the parking garage preventing snow and heat impact • Limitation by summer demand on heat Is Is th this is al all so solar ar in indu dustr stry ca y can do? n do?
Further Options and Demands • Many more roofs • Potential use of waste Heat • Strong increasing need of Cooling • Need of redundancy in the cooling
Smart system integration WASTE HEAT HEAT STORAGE SOLAR YIELD THERMAL COLD WATER DRIVEN COOLING PROCESS PROCESS &DISTRICT CONDITIONED HEATING AIR for Campus COOLING LOAD
Smart integration- solution • Many more roofs ➔ 2043 m² more solar • Potential use of waste Heat ➔ using solar storage • Strong increasing need of Cooling ➔ adding an AHP • Need of redundancy in the cooling heat driven Cooling
Smart integration- solution
Smart system integration advantages • Energy Efficiency • Peak reduction HEAT from District Heating • Renewable Heat Generation • Extended solar potential by • integration of Redundancy • Cooling & Heating Peak load reduction electric demand • Using Solar and Waste to power cooling THERMAL COLD WATER DRIVEN COOLING PROCESS CONDITIONED AIR
Examples in District Heating • Biomas omass s dist strict rict heati ting ng with h solar ar & storage orage • Storage is used as well for peak load management in winter from boiler
Examples in building sector • Combin mbined ed solar ar hot water er, , Cooling oling and heati ting g for large ge buildings (Hospitals, Campus, …) • On sunny days with cooling demand, the sun powers both AC and hot water (summer/hot countries) • On overcast days, the system still delivers all needed hot water (100%) but cooling demand is a lot less to zero • Heating in shoulder seasons/ winter
Summary • To establis ablish a new heat t syst stem em, , we need much more re than only y heat t generati eration on • We need storage as central part (hourly, daily, seasonal) • We need load management • We need integration with cooling and heating • We need integration of other variable heat sources And then n solar ar heat t can play a major or role with th its s advantages tages as one of the cheapest est, , regional ional available, able, most st reliable iable and most st cost t stab able le source ce !
