Webing peak demand. All chiller energy sources have seen rising costs, as well as questions about the stability of supply in some regions. This is leading many engineers to evaluate combinations of electric and non-electric chillers to capture the most advantageous energy pricing, and provide a hedge against future uncertainty WebJun 1, 2010 · This paper presents steady-state hybrid modeling and analysis of water chillers with economized screw compressors using intermediate gas injection. The hybrid chiller model consists of the polynomial neural network compressor model and other component models grounded on the first principles.
