Ice Storage System for Cooke Library, Punahou School
Back to EducationInSynery Engineering provided the mechanical and electrical engineering analysis and design work for a new chilled water ice storage system for Cooke Library at Punahou School.
The evaluation phase included conducting cooling load calculations, field investigations, and monitoring to determine the actual air conditioning load. The economic feasibility for three alternatives for replacement of the air conditioning was evaluated. Option 1 evaluated a Conventional Chilled Water System; Option 2 evaluated a Full Ice Storage Air Coditioning System; and Option 3 evaluated a Partial Ice Storage Air Conditioning System. The findings of the evaluations were summarized in a report, addressing the economic feasibility, construction cost, and phasing issues.
The design phase included the detailed engineering for the construction of a new partial chilled water ice storage system, including two new screw chillers and cooling towers,circulation pumps, and controls. The system has been reliably operating since 2002 and was used as the prototype for the larger ice storge system that now serves most of the campus.
