This paper provides an overview of the model developed
for simulation of steady -state performance of a heat
pump working with a nonazeotropic binary mixture. The
modeled heat pump consists of a hermetic,
reciprocating compressor, flat-finned tube heat
exchangers, a constant flow area expansion device, an
accumulator, a four-way valve, and connecting tubing.
The paper discusses basic concepts in formulation of
models of major heat pump components and overall program
iteration scheme. Verification of the model is presented
in the cooling and heating operating modes
for a heat pump charged with R13Bl/R152a mixture.
