Ice storage |
The ice storage system for the Wake County Social Services Center is designed around a weekly load shifting concept. With this concept, the harvesters (ice makers) produce ice during off-peak hours on weeknights and weekends and do not operate at all during on-peak periods. Weekly load shifting takes advantage of extended weekend hours to downsize ice harvester equipment, thereby minimizing initial capital investment and decreasing the pay-back time. For the Social Services Center, the additional capital investment for ice storage with weekly load shifting is $215,000 compared to a conventional chilled water system. Estimated utility cost savings for the ice storage system is $50,000 per year, yielding a simple pay-back on investment of 4.3 years. Besides utility cost savings, the ice storage system offers several other advantages over a conventional cooling system. The ice storage system produces very low chilled water temperatures, which allows the Wake County Social Services Center to use a low temperature air distribution system. System advantages include smaller air handling units, smaller piping, smaller ductwork, and smaller building pumps as compared to a conventional air system. |
