1200-RP的主要目标是制定一套操作策略，以最大限度地降低混合式冷水机组的操作成本。混合式制冷装置采用电力和天然气驱动的制冷机组合。使用天然气的制冷机包括吸收式和发动机驱动式制冷机。

The primary objective of 1200-RP was to develop a set of operating strategies that minimize operating costs in hybrid chiller plants. A hybrid chiller plant employs a combination of chillers that are “powered” by electricity and natural gas. Chillers that employ natural gas include absorption and engine-driven chillers.
