töövedelikus

Töövedelik is an Estonian term that translates to "working fluid" in English. It refers to a substance that absorbs, transports, and releases thermal energy in a thermodynamic system. Working fluids are essential components in various technologies that involve heat transfer and energy conversion.

Common examples of working fluids include refrigerants used in air conditioning and refrigeration systems, steam in power plants, and air in internal combustion engines. The properties of a working fluid, such as its specific heat capacity, boiling point, and viscosity, are crucial for the efficiency and performance of the system it is used in. Different applications require different working fluids tailored to specific operating conditions and temperature ranges.

The selection of an appropriate working fluid is a critical design consideration in many engineering fields. Factors such as safety, environmental impact, cost, and availability also play a significant role in this selection process. Research and development continue to explore new and improved working fluids to enhance the efficiency and sustainability of various thermal systems.
