What is Condenser (heat transfer)?
[[File:Lednička Zanussi ZRA 319 SW, celkový pohled na zadní část.JPG|thumb|The condenser coil of a refrigerator]] A '''condenser''' is a [[heat exchanger]] used to [[Condensation|condense]] a [[gas]]eous substance into a [[liquid]] state through cooling. In so doing, the [[latent heat]] is released by the substance and absorbed into the environment around it. Condensers are used for efficient heat rejection in many industrial systems. Condensers can be made in multiple designs and they come in many sizes ranging from small (hand-held) to very large (industrial-scale units used in plant processes). For example, a [[refrigerator]] uses a condenser to get rid of [[heat]] extracted from the interior of the unit to the outside air. This cools the food inside of it. Condensers are used in [[air conditioning]], industrial [[chemical process]]es such as [[distillation]], steam [[power plant]]s, and other heat-exchange systems. Use of cooling water or surrounding air as the coolant is common in many condensers.<ref name=chemengenc>{{citation|title=Encyclopedia of Chemical Engineering Equipment|contribution=Condensers|publisher=[[University of Michigan]]|url=http://encyclopedia.che.engin.umich.edu/Pages/HeatTransfer/Condensers/Condensers.html|last1=Hindelang|first1=Man jjhat|last2=Palazzolo|first2=Joseph|last3=Robertson|first3=Matthew|archive-url=https://web.archive.org/web/20121224054052/http://encyclopedia.che.engin.umich.edu/Pages/HeatTransfer/Condensers/Condensers.html|archive-date=24 December 2012|url-status=dead}}</ref> ==Air conditioning== [[File:Condenser unit for central air conditioning.JPG|thumb|Condenser unit for central air conditioning for a typical house]] A ''condenser coil'' used in [[air conditioning]] systems normally has a heat exchanger section to cool down and condense the [[refrigerant]] vapor into liquid, a [[gas compressor|compressor]] to raise the pressure of the refrigerant and move it along, and a fan for blowing outside air through the heat exchanger section to cool the refrigerant inside.
