Abstract

Heat pumps have recently received increasing
interest due to green energy initiatives and increasing energy
prices. In this paper, a nonlinear dynamic model of a singleeffect
LiBr-water absorption cycle heat pump is derived for
simulation and control design purposes. The model is based
on an actual heat pump located at a larger district heating
plant. The model is implemented in Modelica and is based
on energy and mass balances, together with thermodynamic
property functions for LiBr and water and staggered grid
representations for heat exchangers. Model parameters have
been fitted to operational data and different scenarios are
simulated to investigate the operational stability of the heat
pump. Finally, this paper provides suggestions and examples of
derivation of lower order linear models for control design.
