Wärmeträgern

Wärmeträgern, often translated as heat transfer fluids or thermal fluids, are substances used to transport thermal energy from one place to another. They are crucial in a wide variety of applications, from industrial processes and power generation to domestic heating and cooling systems. The primary function of a Wärmeträgern is to absorb heat from a source, move it through a system, and release it at a desired location.

The selection of an appropriate Wärmeträgern depends on several factors, including the operating temperature range, pressure conditions, material compatibility, and environmental considerations. Common types include water, glycols (like ethylene glycol and propylene glycol), mineral oils, synthetic oils, and molten salts. Water is the most common and cost-effective option for many applications, but its freezing point and boiling point can limit its use in extreme temperatures. Glycols are often used in systems where freezing protection is necessary, such as in solar thermal collectors and automotive cooling systems. Oils are suitable for higher temperature applications where water would vaporize.

Wärmeträgern play a vital role in improving energy efficiency and enabling controlled thermal management. Their effectiveness is determined by properties such as specific heat capacity, thermal conductivity, viscosity, and thermal stability. By facilitating the efficient movement of heat, they contribute to optimizing processes, maintaining comfortable environments, and reducing energy consumption.
