An analysis of the vapor compression cycle and the main
components of an air source heat pump during
steady-state operation has been performed with emphasis
on fundamental phenomena taking place between key
locations in the refrigerant system. The basis of the
general heat pump model formulation is the logic which
links the analytical models of heat pump components
together in a format requiring an iterative solution of
refrigerant pressure, enthalpy and mass balances. The
modeling effort emphasis was on the local thermodynamic
phenomena which were described by fundamental heat
transfer equations and equation of state relationships
among material properties.
