A modular, steady-state model for the simulation of
absorption heat pumps (AHP) is presented. The model is
based on detailed mass and energy balances and heat and
mass transfer relationships from components of the
cycle and is applied to a prototype AHP and compared
with experimental data. The qualitative behavior of the
simulated COP and system temperatures, compositions, and
heat flows generally agrees with experimental
results. The usefulness of the model in design studies
is demonstrated by a factorial analysis investigating
sensitivity of the AHP to changes in design parameters.
