EVAPORATOR MODELS FOR OPERATION WITH DRY, WET, AND FROSTED FINNED SURFACES. 1. HEAT TRANSFER AND FLUID FLOW THEORY.

Author(s) : OSKARSSON S. P., KRAKOV K. I., LIN S.

Summary

EVAPORATOR MODELS FOR OPERATION WITH DRY, WET, AND FROSTED SURFACE CONDITIONS REQUIRE EQUATIONS FOR BOTH AIR-SIDE AND REFRIGERANT-SIDE HEAT TRANSFER COEFFICIENTS AND PRESSURE LOSS FACTORS. THE PAPER DETAILS THE HEAT TRANSFER COEFFICIENTS, MASS TRANSFER COEFFICIENTS, AND PRESSURE LOSS FACTORS FOUND IN THE CURRENT LITERATURE THAT YIELDED THE BEST CORRELATION BETWEEN DATA SIMULATED BY EVAPORATOR MODELS DEVELOPED AND DATA OBTAINED EXPERIMENTALLY BY THE AUTHORS. EQUATIONS FOR THE CALCULATION OF FROST ACCUMULATION AND ITS EFFECTS ON EVAPORATOR PERFORMANCE ARE INCLUDED IN THE PAPER. THE INCLUSION OF THE EFFECTS OF FROST IS REQUIRED FOR EVAPORATORS USED IN HEAT PUMPS.
