About The Customer
The Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg, Germany, is one of the world's leading research organizations in the field of solar energy transformation, storage, and use. With a staff of approximately 1,300 employees, the institute is part of a network of over 65 Fraunhofer research institutes in Germany specializing in various aspects of applied science. Researchers at Fraunhofer ISE, including Eric Laurenz and Hannes Fugmann, are part of a 20-person group led by Lena Schnabel, focusing on developing higher-efficiency heat exchangers for adsorption systems. The team uses a combination of simulation and small-scale experiments to build large-scale models that accurately predict the complex real-world behavior of the physics being investigated.
The Challenge
The heating and cooling of buildings account for nearly 50 percent of energy consumption in Europe, prompting researchers to seek alternatives to conventional technologies. One promising solution is adsorption-based heating and cooling systems driven by heat rather than electricity. This technology can utilize heat from solar collectors, waste heat from industrial facilities, or combined heat and power units, significantly reducing electricity consumption and CO2 emissions. However, the development of these systems is complex due to their discontinuous operating cycles, varying peak energy fluxes, and the dynamic behavior determined by complex heat and mass transfer phenomena. To realize their full potential, the technology must become more efficient, compact, and cost-effective.
The Solution
The team at Fraunhofer ISE uses a combination of simulation and well-defined, small-scale experiments to build large-scale models that can accurately predict the complex real-world behavior of adsorption-based heating and cooling systems. This approach significantly reduces the need to build full-size physical prototypes, saving both time and money. One key objective is to optimize the uptake speed and capacity of the thin sorbent layers used in the system. Using COMSOL Multiphysics, the team can simulate coupled physics in complex and dynamic systems, which has proven indispensable for their research. In optimizing heat exchanger architectures, Fugmann performs basic research on designs, including chillers and heat pumps, using wire structures to increase heat transfer surface area. These novel architectures are analyzed both experimentally and numerically for use as sorptive-coated structures and as surface enlargement for heat exchangers in thermal storages.

Vestas: Turning Climate into Capital with Big Data
Making wind a reliable source of energy depends greatly on the placement of the wind turbines used to produce electricity. Turbulence is a significant factor as it strains turbine components, making them more likely to fail. Vestas wanted to pinpoint the optimal location for wind turbines to maximize power generation and reduce energy costs.

Siemens Wind Power
Wind provides clean, renewable energy. The core concept is simple: wind turbines spin blades to generate power. However, today's systems are anything but simple. Modern wind turbines have blades that sweep a 120 meter circle, cost more than 1 million dollars and generate multiple megawatts of power. Each turbine may include up to 1,000 sensors and actuators – integrating strain gages, bearing monitors and power conditioning technology. The turbine can control blade speed and power generation by altering the blade pitch and power extraction. Controlling the turbine is a sophisticated job requiring many cooperating processors closing high-speed loops and implementing intelligent monitoring and optimization algorithms. But the real challenge is integrating these turbines so that they work together. A wind farm may include hundreds of turbines. They are often installed in difficult-to-access locations at sea. The farm must implement a fundamentally and truly distributed control system. Like all power systems, the goal of the farm is to match generation to load. A farm with hundreds of turbines must optimize that load by balancing the loading and generation across a wide geography. Wind, of course, is dynamic. Almost every picture of a wind farm shows a calm sea and a setting sun. But things get challenging when a storm goes through the wind farm. In a storm, the control system must decide how to take energy out of gusts to generate constant power. It must intelligently balance load across many turbines. And a critical consideration is the loading and potential damage to a half-billion-dollar installed asset. This is no environment for a slow or undependable control system. Reliability and performance are crucial.

Remote Monitoring and Control for a Windmill Generator
As concerns over global warming continue to grow, green technologies are becoming increasingly popular. Wind turbine companies provide an excellent alternative to burning fossil fuels by harnessing kinetic energy from the wind and converting it into electricity. A typical wind farm may include over 80 wind turbines so efficient and reliable networks to manage and control these installations are imperative. Each wind turbine includes a generator and a variety of serial components such as a water cooler, high voltage transformer, ultrasonic wind sensors, yaw gear, blade bearing, pitch cylinder, and hub controller. All of these components are controlled by a PLC and communicate with the ground host. Due to the total integration of these devices into an Ethernet network, one of our customers in the wind turbine industry needed a serial-to-Ethernet solution that can operate reliably for years without interruption.
