lämmönsiirtolietteet

Lämpönsiirtolietteet, known in English as heat transfer fluids, are substances used to transport thermal energy from one location to another. They are essential components in a wide range of heating, ventilation, and air conditioning (HVAC) systems, as well as industrial processes. The primary function of a lämmönsiirtoliuos is to absorb heat from a source, move it through a closed or open loop, and then release it to a destination.

These fluids are typically liquids or gases that exhibit favorable thermal properties, such as high specific heat capacity and thermal conductivity, while maintaining low viscosity for efficient flow. Common examples include water, glycols (ethylene glycol and propylene glycol), and mineral oils. In many applications, especially those involving refrigeration or where freezing is a concern, glycols are mixed with water to lower the freezing point and raise the boiling point of the fluid, thereby expanding its operating temperature range. Additives may also be incorporated to prevent corrosion, inhibit microbial growth, or improve lubrication. The selection of a specific lämmönsiirtoliuos depends on factors such as the operating temperature, pressure, material compatibility within the system, environmental considerations, and cost. Proper maintenance and monitoring of lämmönsiirtolietteet are crucial for ensuring the efficiency and longevity of the systems they serve.
