Summary

THE PAPER PRESENTS A CLOSED-FORM ANALYTICAL METHOD FOR THE SECOND-LAW-BASED THERMOECONOMIC OPTIMIZATION OF TWO-PHASE HEAT EXCHANGERS USED AS CONDENSERS OR EVAPORATORS. THE CONCEPT OF < INTERNAL ECONOMY > AS A MEANSOF ESTIMATING THE ECONOMIC VALUE OF ENTROPY GENERATED (DUE TO FINITE TEMPERATURE DIFFERENCE HEAT TRANSFER AND PRESSURE DROPS) HAS BEEN PROPOSED, THUS PERMITTING THE ENGINEER TO TRADE THE COST OF ENTROPY GENERATION IN THE HEAT EXCHANGER AGAINST ITS CAPITAL EXPENDITURE. THE ANALYSIS OF A WATER-COOLED CONDENSER AND AN AIR-COOLING EVAPORATOR IS PRESENTED.
