Development of a large-tonnage engine-driven chiller with integrated thermal storage. Annual report, September 1988-September 1989
The widespread use of high demand charges and time of use energy rates by electric utilities has attracted engineers and building owners to various peak shaving strategies. Gas chillers and thermal energy storage are two technologies that have been updated and are generally thought to be competing in the market place. The combination of these two strategies into one competitively priced product is the goal of the Gas Research Institute/American Gas Association project. The analysis phase is presented in the report. The economic analysis consisted of office building load and equipment simulations in ESAS, thermal storage sizing and strategy, installed costs of chillers and heat rejection equipment, and utility rate inputs. Maintenance and replacement costs during a 25 year plant life are included. A standard electric centrifugal chiller is used as a base case. The results indicate that the engine-driven thermal storage system can be economically attractive due to lower first cost than gas chillers of the same rated capacity. Electric-drive thermal storage, engine-driven thermal storage and engine-driven chillers are each competitive under different utility rate structures.
