    In a chilled water system, the chilled water is distributed by a pump through supply and return piping. Chilled water is piped to each AHU where the chilled water cools the air. The main components of an AHU consist of a cooling coil and a supply fan. Chilled water flows though the The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD(AT&L) Memorandum dated 29 May 2002.

    The most popular large commercial building chilled water system today is the primary-secondary design.
