Description

Discusses the design and preliminary operating information for the prototype ice harvester thermal storage, inlet air-cooling system for a peaking turbine. The refrigeration/storage system consists of a 1.1-million-gal (41.6-million-L) tank that stores 37,400 ton-hours (473-500 GJ) of harvested ice from three evaporators. It is serviced by a 700-hp (522.2-kW), 600-ton (2,100-kW) rotary screw compressor using ammonia as the refrigerant. The system cools an inlet air flow of 431,000 cfm (203-400 L/s) of air from 101.5 deg F (38.6 deg C) and 77 deg F (25 deg C) wet bulb to 40 deg F (4.4 deg C) for 4 hours on five weekdays. The presentation includes a statement of design objectives, development of design conditions, consideration of system and component alternatives, and preliminary information on operation.

KEYWORDS: inlets, air, cooling, combustion, turbines, energy storage, prototypes, refrigeration, designing, operations, evaporators, rotary compressors, ammonia, refrigerants.
