Summary

THE PERFORMANCE OF THREE COMBINED ABSORPTION/VAPOUR COMPRESSION CYCLES WAS ASSESSED IN A THEORETICAL STUDY WITH REGARD TO THEIR FEASIBILITY TO ENHANCE THE EFFICIENCY AND CAPACITY OF GAS-FIRED INTERNAL COMBUSTION ENGINE-DRIVEN HEAT PUMPS. THE COPS AND THE CAPACITY HAVE BEEN CALCULATED FOR HEATING AND COOLING APPLICATIONS. OPERATING PARAMETERS AND THE HEAT DUTIES WERE ALSO INVESTIGATED. WHEN ALL OF THE EXHAUST HEAT IS USED FOR HEAT PUMPING IN ADDITION TO THE WORK OUTPUT, THEN A PERFORMANCE IMPROVEMENT WITH REGARD TO BOTH, CAPACITY AND COP, OF UP TO 31% FOR COOLING AND 17% FOR HEATING CAN BE ACCOMPLISHED WITH THE DESORBER-ABSORBER HEAT EXCHANGE (DAHX) CYCLE, AND, RESPECTIVELY, 21 AND 11% FOR THE SIMPLE ABSORPTION CYCLE (SC). THE TOTAL HEAT DUTY INCREASES UP TO 32% FOR THE DAHX CYCLE AND 23% FOR THE SC COMPARED WITH CONVENTIONAL ENGINE-DRIVEN SYSTEMS.
