SIMULATION MODEL AND THERMODYNAMIC DESIGN OF AN ADVANCED ABSORPTION HEAT PUMP FOR SOLAR SPACE HEATING.

THE SYSTEM CONSISTS OF TWO-STAGE REFRIGERANT VAPOUR GENERATION WITHIN THE ABSORPTION CYCLE ALONG WITH TWO HEAT RECUPERATORS BETWEEN THESE GENERATORS AND THE ABSORBER. A CONCEPTUAL THERMODYNAMIC DESIGN BASED ON A SIMULATION MODEL SATISFYING HEAT, MASS AND MATERIAL BALANCE EQUATIONS FOR EACH OF THE SYSTEM COMPONENTS HAS BEEN OBTAINED FOR THE IMPROVED ABSORPTION HEAT PUMP SYSTEM. THE SIMULATION MODEL EMPLOYING INPUT HEAT SUPPLY, PUMPING POWER AND AMBIENT CONDITIONS AS INPUT VARIABLES IS CAPABLE OF PREDICTING THE HEAT PUMP PERFORMANCE UNDER OPTIMUM DESIGN AND OFF-DESIGN CONDITIONS.
