Demonstration Ice Storage with Waste-Heat-Recovery Project. Final Report

摘要

The goals of the reported project were to: construct a compact, package-type cooling system; test ice storing capacity in relation to time, weight, and total energy consumption; design and install an ice bank system with heat recovery capacity in a residence; and meter and monitor the system in operation and compare with other systems in similar residences for energy consumption, material, and maintenance costs. An ice bank cooling system was laboratory tested and a working unit was installed in a new 3-bedroom house. The system consists of an insulated storage tank in which water is cooled by a commercial refrigeration unit during the night hours. During the day, the chilled water is circulated by pump to an indoor coil located in the air duct system. The heat exhausted by the refrigeration unit is captured by a heat exchange unit. Water is circulated through the heat exchanger and a water heater. Detailed information concerning the construction and installation of the system is provided, as well as data gathered during operation. (ERA citation 08:012570)
