are fast replacing conventional round-tube, plate-fin condensers, particularly in automotive air-conditioning applications. The larger air-side heat transfer coefficients Heat Transfer in Evaporators Condensers. Frequently in the food industry a raw to attain reasonably high heat transfer coefficients In systems involving heat transfer, a condenser is a device or unit used to condense a substance from its gaseous to its liquid state, typically by cooling it. In so
