lämmönsiirtonesteen

Lämönsiirtoneste, known in English as heat transfer fluid, is a substance used to transport thermal energy from one location to another. Its primary function is to absorb heat at a source and release it at a destination, facilitating temperature regulation and energy transfer in various systems. These fluids are crucial components in applications ranging from industrial processes and power generation to heating and cooling systems in buildings and vehicles.

The selection of a suitable lämmönsiirtoneste depends on several factors, including the operating temperature range, the required thermal properties such as specific heat and thermal conductivity, viscosity, and chemical stability. Common types of heat transfer fluids include water, various glycols (like ethylene glycol and propylene glycol), mineral oils, synthetic oils, and silicone-based fluids. Water is an excellent heat transfer medium due to its high specific heat capacity and availability, but its use is limited by its freezing and boiling points. Glycols are often added to water to lower its freezing point and raise its boiling point, making it suitable for a wider temperature range.

In industrial settings, heat transfer fluids are employed in heat exchangers, chemical reactors, and manufacturing processes where precise temperature control is essential. In automotive applications, coolant mixtures in engines serve as lämmönsiirtoneste to prevent overheating. Residential and commercial heating and cooling systems, such as solar thermal systems and geothermal heat pumps, also rely on these fluids to efficiently distribute thermal energy. The efficiency and longevity of a heat transfer system are significantly influenced by the properties and condition of the lämmönsiirtoneste used.
