Summary

THE CONDENSER AND THE EVAPORATOR OF ACOMPRESSION REFRIGERATING MACHINE WERE MODELLED BY MEANS OF A SUBDIVISION OF DESUPERHEAT, CONDENSATION AND SUBCOOLING ZONES FOR THE CONDENSER, VAPORIZATION AND SUPERHEATING ZONES FOR THE EVAPORATOR. THE ANALYSIS OF A MODEL WITH LOCAL COEFFICIENTS LEADS TO SUGGEST A SIMPLER MODEL WITH ZONE COEFFICIENTS. THESE MODELS SATISFACTORILY DESCRIBE THE OPERATION OF HEAT EXCHANGERS UNDER STATIONARY OR QUASI-STATIONARY CONDITIONS, BUT SHOULD BE USED ONLY WITH PRECAUTION IN THE CASE OF UNSTEADY CONDITIONS.
