Summary

DESCRIBES A PARAMETER STUDY OF A HEAT PUMP DRIVEN ALTERNATELY BY A GAS TURBINE ENGINE AND A DIESEL ENGINE. THE VARIABLES WERE THE EVAPORATING TEMPERATURE OF THE REFRIGERANT, THE EFFECTIVENESS OF THE HEAT EXCHANGER, THE CONDENSER TEMPERATURE AND THE TYPE OF REFRIGERANT. CANDIDATE REFRIGERANTS WERE R12, R22, R114 AND R500. NOTES A COMPUTER PROGRAM COMPILED TO CARRY OUT THE PARAMETRIC PERFORMANCE ANALYSIS. PRESENTS AND DISCUSSES THE RESULTS AND SUPPLIES AN ECONOMIC ANALYSIS. CONCLUDES THAT THE COMBINED PERFORMANCE AND ECONOMIC ANALYSIS SHOWS THAT THE GAS TURBINE PUMP IS SUPERIOR IN SAVING SPACE WEIGHT AND IN IMPROVING THE ECONOMY OF THE HEAT PUMP. (INT. BUILD. SERV.
