Abstract:

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 the sensitivity of the AHP to changes in design parameters.
