While most data centers use air-cooled chillers that have free cooling coils to benefit from lower ambient conditions, air-cooled, magnetic bearing centrifugal chillers can operate at inverted conditions and provide free cooling without the need for additional coils.
Whether it’s engineering a new campus distribution system, reengineering one, or adding an extension to one for a new building on the campus, hydraulic modeling is an essential design tool.
