PREDICTION OF CYCLIC HEAT PUMP PERFORMANCE WITH A FULLY DISTRIBUTED MODEL AND A COMPARISON WITH EXPERIMENTAL DATA.

Author(s) : MACARTHUR J. W., GRALD E. W.

Summary

DUE TO THE IMPORTANCE OF THERMAL EXPANSION AND COMPRESSIBILITY EFFECTS, A DETAILED MATHEMATICAL TREATMENT IS GIVEN OF THE CONDENSER, EVAPORATOR, AND ACCUMULATOR. A BRIEF DESCRIPTION IS PRESENTED OF THE SOLUTION METHODOLOGY EMPLOYED. LUMPED-PARAMETER MODELS WERE DEVELOPED FOR THE EXPANSION DEVICE, NATURAL-GAS-FUELED INTERNAL COMBUSTION ENGINE, AND COMPRESSOR. SINCE INCLUSION OF AN APPROPRIATE VOID FRACTION MODEL WAS FOUND TO BE ESSENTIAL IN DETERMINING THE DETAILED REFRIGERANT MASS DISTRIBUTION, THIS TOPIC IS ALSO DISCUSSED. SIMULATION RESULTS AND EXPERIMENTAL DATA ARE FAVOURABLY COMPARED FOR TRANSIENT OPERATION OF A HERMETIC WATER-TO-WATER HEAT PUMP AND AN AIR-TO-AIR SYSTEM WITH AN OPEN COMPRESSOR.
