Translocation itself has been shown to be an exergonic reaction (56, 57), but with a high free energy of activation [ÎG â  â 96 kJ/mol for factor-free translocation (58, 59)].
High chilled water temperature: Normally chilled water is delivered into the piping system at a temperature between 42Â°F and 46Â°F. This is the water temperature that should be present at the supply connection on the air handler. Some buildings vary the temperature of chilled water with outdoor temperature change.
This is termed the âapproach.â For example, a cooling tower with a 7Â°F approach is capable of reducing. the supply water temperature to within 7 degrees of the wet bulb. Most chillers are designed to operate at a cooling water supply temperature of 85Â°F with a 95Â°F return. temperature to the cooling tower. However, lower cooling water supply temperatures improve chiller. efficiency by 1% to 2% for every 1Â°F decrease in supply temperature. Conversely, chiller efficiency is.
