Summary

THE THERMODYNAMIC EFFICIENCY OF HEATING PLANT OF PREMISES, ACCORDING TO THE SECOND LAW OF THERMODYNAMICS, IS IN GENERAL VERY LOW. A HEAT QUANTITY WITH A LITTLE EXERGY CONTENT CAN BE SUPPLIED EITHER BY A COGENERATION PLANT OR BY A HEAT PUMP SYSTEM. NEVERTHELESS THE HEAT PUMPS HAVE AN EXERGETIC EFFICIENCY NO BETTER THAN 20%. CONSEQUENTLY ANY EFFORT MUST BE CARRIED OUT FOR IMPROVING SUCH AN EFFICIENCY. SOME ELEMENTS OF VAPOUR COMPRESSION HEAT PUMP SYSTEMS ARE CONSIDERED ; IMPROVEMENTS ARE DISCUSSED WITH REGARD TO THE COMPRESSORS, TO THE HEAT EXCHANGERS AND TO THE CAPACITY CONTROL METHODS.
