Nomenclature
Cooling water is the water removing heat from a machine or system. Cooling water may be recycled through a recirculating system or used in a single pass once-through cooling (OTC) system. Recirculating systems may be open if they rely upon cooling towers or cooling ponds to remove heat or closed if heat removal is accomplished with negligible evaporative loss of cooling water. A heat exchanger or condenser may separate non-contact cooling water from a fluid being cooled, or contact cooling water may directly impinge on items like saw blades where phase difference allows easy separation. Environmental regulations emphasize the reduced concentrations of waste products in non-contact cooling water.
