Lämpönsiirtoliuos

Lämpönsiirtoliuos, often translated as heat transfer fluid, is a substance used to transport thermal energy from one place to another. Its primary function is to absorb heat from a source and release it at a desired location, facilitating processes such as heating, cooling, and power generation. These fluids are crucial components in many industrial and domestic applications.

The selection of a lämpönsiirtoliuos depends on several factors, including the operating temperature range, pressure, compatibility with system materials, and environmental considerations. Common examples include water, various glycols (such as ethylene glycol and propylene glycol), mineral oils, synthetic oils, and molten salts. Water is widely used due to its excellent thermal properties, low cost, and environmental friendliness, but its use is limited by its freezing and boiling points. Glycols are often used in applications where freezing is a concern, as they lower the freezing point of water.

In addition to their thermal conductivity and heat capacity, lämpönsiirtoliuokset are also evaluated for their viscosity, which affects pumping efficiency and pressure drop within the system. Chemical stability is also important to prevent degradation and the formation of corrosive byproducts. The design and maintenance of systems utilizing lämpönsiirtoliuos are critical to ensure efficient and safe operation. Regular monitoring of fluid properties and system integrity helps to prevent issues such as leaks, corrosion, and reduced performance.
