Fouling phenomena are common and diverse, ranging from fouling of ship hulls, natural surfaces in the
marine environment (marine fouling), fouling of heat-transfer components through ingredients contained in
the cooling water or gases, and even the development of plaque or calculus on teeth, or deposits on solar
panels on Mars, among other examples.
Foreign matter in the chilled water system will adversely affect the heat transfer capability of the evaporator,
and could increase the pressure drop and reduce the water flow. To provide optimum unit operation, proper
water treatment must be maintained. Refer to the able as following.
