Pinch analysis, also known as process integration, is used to systematically link process streams to reduce energy demand.
Hardware in the Loop (HiL) testing is not just for the automotive industry! Our experience with simulation-based control development for thermal systems such as heat pumps, refrigeration plants or fuel cells.
Feedback in control loops is the basic concept of control engineering on which everything else is based. We explain this concept without mathematics, only using illustrative examples. Gain an intuitive understanding of why control loops can become unstable. And learn what is crucial for good control design.
Promote CO2 neutrality in companies - learn more about the general levers in the TLK Energy Blog. Reduce CO2 emissions through decarbonization, energy efficiency and compensation.
It sounds contradictory: What does a refrigeration cycle do in a heat pump? Resolving precisely this apparent contradiction is the key to understanding the fundamentals and functioning of refrigeration cycles – and heat pumps.
PI and PID controllers are the most frequently used controllers in practice. Even though the actual control law is very simple, the selection of suitable parameters is anything but trivial. We present a practical and well-proven step-by-step method to determine good PID parameters for a given application.
How are individual apps for the simulation of technical processes developed? What additional value can simulation with an online tool offer in the fields of engineering, sales and technical marketing? We show you which steps are necessary to transfer complex models into an intuitive app.
When is a parameter study appropriate? And how should one proceed? We present a tool chain from the simulation model in Modelica, FMU export and the use of Python scripts to visual data exploration.
Receivers or accumulators are often used in refrigeration cycles. They are basically very simple components, but their function in the overall system is quite complex. We want to take a closer look at them and understand the effects on the overall refrigeration system.
How can the heating capacity of a car be calculated with the help of simulation? Why is this interesting for electric cars that suffer from a loss of range in winter? We show you how to determine the heating power under various boundary conditions using a physical vehicle cabin model and simulation technology.
Computer simulations often differentiate between steady state and dynamic simulation. We want to define these terms more precisely and explain the differences.
