What is the fouling factor in a chilled water system?
Impurities in the chilled water system eventually deposit on evaporator tube surfaces, impeding heat transfer. Cataloged performance data includes a “fouling factor” that accounts for this effect to more closely predict actual chiller performance.
What does fouling mean in terms of solidification?
Solidification fouling – when components of the flowing fluid with a high-melting point freeze onto a subcooled surface Limescale buildup inside a pipe both reduces liquid flow through the pipe, as well as reduces thermal conduction from the liquid to the outer pipe shell.
How is fouling different from other growth phenomena?
Fouling is usually distinguished from other surface-growth phenomena, in that it occurs on a surface of a component, system or plant performing a defined and useful function, and that the fouling process impedes or interferes with this function.
What’s the difference between micro fouling and macro fouling?
Fouling. In the cooling technology and other technical fields, a distinction is made between macro fouling and micro fouling. Of the three, micro fouling is the one which is usually more difficult to prevent and therefore less important.
