Summary

A THERMODYNAMIC ANALYSIS OF HYBRID SYSTEMS INCORPORATING METAL HYDRIDE HEAT TRANSFORMERS (MHHT) AND VAPOUR COMPRESSION HEAT PUMPS (VCHP) IS PRESENTED. 2 HYBRIDIZATION CONCEPTS ARE ANALYSED. IN HYBRID 1, THE HEAT ABSORBED AT THE EVAPORATOR OF VCHP IS MATCHED WITH THE HEAT REJECTED AT LOW TEMPERATURE IN THE MHHT. IN HYBRID 2, THE CONDENSER HEAT REJECTION OF VCHP IS MATCHED WITH THE HEAT SUPPLY TO MHHT AT THE INTERMEDIATE TEMPERATURE LEVEL. 8 DIFFERENT METAL HYDRIDE PAIRS ARE CONSIDERED. R12 AND R11 ARE CONSIDERED AS COMPRESSION WORKING FLUIDS. PERFORMANCE OF HYBRID SYSTEMS IS COMPARED WITH THAT OF SINGLE STAGE OR CASCADED VCHP SYSTEMS. THE HYBRID 2 CONCEPT IS MORE ADVANTAGEOUS OVER A WIDE RANGE OF TEMPERATURE LEVELS.
