EVAPORATOR MODELS FOR OPERATION WITH DRY, WET, AND FROSTED FINNED SURFACES. 2. EVAPORATOR MODELS AND VERIFICATION.

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

Summary

THREE MODELS FOR FINNED EVAPORATORS ARE PRESENTED: A FINITE ELEMENT MODEL, ANALYZING THE COIL IN GEOMETRICALLY FIXED ELEMENTS, IS USED TO STUDY THE LOCAL BEHAVIOUR OF HEAT TRANSFER FLUIDS AND THE EFFECT OF REFRIGERANT-SIDE PRESSURE DROP ON HEAT TRANSFER PERFORMANCE ; A THREE-REGION MODEL, NEGLECTING REFRIGERANT-SIDE PRESSURE DROP EFFECTS ON EVAPORATOR PERFORMANCE AND ANY DEHUMIDIFICATION IN THE REGION OF SUPERHEATED REFRIGERANT, IS DERIVED FOR USE IN EVAPORATOR ANALYSIS AND DESIGN ; FINALLY, A PARAMETRIC MODEL IS CONSTRUCTED IN WHICH COIL PERFORMANCE IS DESCRIBED BY A COIL CHARACTERISTIC AND A COIL EFFECTIVENESS PARAMETER. THIS PARAMETRIC MODEL IS SUITABLE FOR USEIN HEAT PUMP SIMULATION PROGRAMS. THE MODELS PREDICT EVAPORATOR PERFORMANCE UNDER DRY, WET, AND FROSTED SURFACE CONDITIONS.
