Partially decentralized control of large-scale variable-refrigerant-flow systems in buildings.

Highlights: [•] Separate linearized models are derived for the fluid dynamics and the thermal dynamics. [•] The proposed control architecture is motivated by the clear structure in the derived models. [•] Local controllers are completely decentralized to be easily scalable with the number of evaporators. [•] Global controller regulates composite superheat to meet global performance objectives. [•] Proposed control architecture and design is demonstrated through a simulated case study. [ABSTRACT FROM AUTHOR]
