Nedkølingen
Nedkølingen is the process of reducing the temperature of a substance or system to a value below its surrounding environment by removing heat to a colder reservoir. It is a general term used in Danish for cooling down, and is applied across science, industry and daily life. The process is driven by heat transfer: conduction through materials, convection by fluids, and radiation, and is influenced by the temperature difference, thermal properties of the substance, and the characteristics of the cooling medium. In many cases the rate of nedkølingen is described by simple models such as Newton's law of cooling.
In food processing and storage, nedkølingen slows microbial growth and chemical reactions. Refrigeration typically targets near
Considerations during nedkølingen include avoiding thermal shock, condensation and ice formation, and ensuring energy efficiency. Rapid
Etymology: the term combines the Danish prefix ned- meaning down with køling meaning cooling.
