The most widely used form of this technology can be found in campus-wide air conditioning or chilled water systems of large buildings. Air conditioning systems, especially in commercial buildings, are the biggest contributors to peak electrical loads seen on hot summer days in various countries. In this application, a standard chiller runs at night to produce an ice pile. Water then circulates through the pile during the day to produce chilled water that would normally be the chil…

Ice Storage or Chilled Water Storage? Which Is Right for the Job?

Markets - Both chilled water and ice storage work for large facilities such as schools, hospitals and offices. If the building has loads with a very short duration (30 minutes to 2 hours) then chilled water storage may be a better choice due to the quicker discharge rates.
