Chilled Water Project

Chilled water is commonly used in buildings to provide cooling. Typically, water is cooled in chiller units, and is then distributed by pipework to air handling units where it is used to cool air that is ducted through the building for ventilation. It can also be used for the dehumidification of ventilation air.Chemical treatment (or dosing): Proprietary (like NALCOOL) or generic chemicals (like Sodium Silicate, Sodium Nitrite, and Sodium Sulfite) compositions are used to prevent the chiller system from corrosion, scaling, fouling and microbiological growth.Temperature/Pressure: Building chilled water system design shall typically be based upon the delivery of 43 degree F supply water to the building service entrance at a supply/return differential pressure of 25 PSI minimum.
