temperaturmedium

Temperaturmedium is a German term that translates to "temperature medium" or "heat transfer medium" in English. It refers to any substance used to transfer thermal energy from one point to another. This transfer can be for heating or cooling purposes. The choice of temperaturmedium depends heavily on the specific application and its requirements, such as the operating temperature range, pressure, chemical compatibility, safety considerations, and cost.

Common examples of temperaturmedien include water, which is widely used due to its availability, low cost, and excellent heat capacity, especially in hydronic heating and cooling systems. Oils, such as mineral oils or synthetic oils, are often employed in applications requiring higher temperatures or where water's freezing point is a concern. Gases like air or nitrogen can also serve as temperaturmedien, particularly in applications where a liquid medium is undesirable or impractical. Refrigerants are specialized temperaturmedien designed for refrigeration and air conditioning cycles, operating under specific pressure and phase change conditions to absorb and release heat. Other specialized fluids, like molten salts, are used in high-temperature industrial processes and solar thermal power plants. The efficiency and safety of a thermal system are significantly influenced by the properties and proper handling of its chosen temperaturmedium.
