Abstract

This paper develops a steady-state system design model for a standard 18 ft3 refrigerator/freezer. Models for the compressor, condenser, evaporator, and suction line interchanger are considered. Experimental data for both R12 and R134a are used as a basis to calibrate the models and as a basis of comparison of model validity for different refrigerants. For each model, a set of independent model parameters are determined from the experimental data using optimization methods. For the heat exchangers both constant conductance and variable conductance models are considered. Lastly, a preliminary overview is made of the applicability of a quasi-steady refrigerator model for use in describing normal cycling operation of a refrigerator/freezer.
