Jahutusviis

Jahutusviis is a term used in Estonian to denote a method or technique for reducing temperature. It literally combines jahutus (cooling) and viis (way), and is employed in technical, industrial, and scientific contexts to describe how something is cooled, not just how cold it becomes. The term is often used interchangeably with jahutusmeetod, jahutustehnika or jahutamise viis in everyday technical writing.

Typical jahutusviis describe the mechanism and the medium: conduction cooling (heat transfer through a solid or stationary medium), convection cooling (removal of heat by moving air or liquid), evaporative cooling (heat is carried away by vaporization, often using a wet surface or air-water interaction), and radiative cooling (emission of infrared radiation to surrounding space). Cooling systems may use various media, such as air, water, refrigerants, or cryogenic liquids, depending on temperature targets and scale. In engineering practice, jahutusviis are specified with capacity (power), efficiency (COP or EER), operating temperature range, and compatibility with load.

Applications span electronics cooling (chip and enclosure cooling), industrial processes (metalworking, chemical processing), data centers, climate control in buildings, food preservation, and medical or laboratory cryogenics. Environmental and safety considerations influence choice of jahutusviis, for example the global warming potential of refrigerants, energy consumption, and safety of cryogenic fluids. Standards bodies provide guidelines for selecting appropriate methods based on heat load, space, and cost.
