Summary

HYBRID REFRIGERATION CYCLES WHICH COMBINE A MECHANICAL COMPRESSOR AND AN ABSORPTION CYCLE IN SUCH A WAY THAT THEY SHARE A SINGLE EVAPORATOR WERE ANALYSED. THE MOTIVATION WAS THE NEED TO MORE EFFICIENTLY UTILIZE THE OUTPUT OF AN INTERNAL COMBUSTION ENGINE. THE HYBRID CYCLES MAKE EFFICIENT USE OF BOTH THE WORK AND THE HEAT OUTPUT OF AN ENGINE. PERFORMANCE CALCULATIONS ARE REPORTED FOR A PROMISING CYCLE WHICH UTILIZES WATER-LITHIUM BROMIDE AS THE WORKING FLUID. FOR THIS WORKING FLUID, THE REFRIGERANT IS WATER. THE WATER-LITHIUM BROMIDE MACHINE WAS COUPLED WITH AN OIL-FREE STEAM COMPRESSOR (SCREW COMPRESSOR). THIS COMBINATION LEADS TO HIGH COST AND LOW PERFORMANCE BUT IS VERY SIGNIFICANT FROM A THERMODYNAMIC VIEWPOINT. IMPROVEMENTS IN STEAM COMPRESSORS CAN BE EXPECTED.
