Simulation of a Heat Pump Operating With a Nonazeotropic Mixture

Published

Author(s)

Piotr A. Domanski, David Didion

Abstract

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.
