Control strategies of absorption heat pumping systems (AHPS, comprising heat pumps and chillers) often performinsufficiently well, since they usually do not explicitly consider the systems’ dynamics and cross-coupling effects.One promising approach to improve their performance is to apply model-based control strategies since they wouldallow for an explicit consideration of these system characteristics. Therefore, mathematically simple models of thesystem to be controlled are required. This contribution proposes a new approach for such a model for a H2O-LiBrAHPS. The model results from the linearization of a more complex, nonlinear simulation model, leading to asimple, but physically still meaningful linear state-space model structure. The experimental validation shows thatthe developed model describes the system’s dynamics and cross-coupling effects sufficiently well and indicates thatit is suitable to serve as a basis for the development of a model-based control strategy for AHPS.
