Abstract: Two-part article describes a 250 x 82 x 22 ft underground concrete tank that stores about 29,000 ton-hours of cooling effect for Yale University's medical school complex. The thermal storage and pumping system increased the capacity of the central chilled water plant from 5,000 tons to about 8,000 tons. Also described is Energy Park, a 218 acre industrial/commercial/residential development in St. Paul, Minn., where a central plant provides heating and cooling for more than 20 buildings. Heat pumps extract thermal energy from groundwater, and plans call for reinjection to store thermal energy in the aquifer.
