CONCEPTUAL DESIGN AND PERFORMANCE ANALYSIS OF ABSORPTION HEAT PUMPS FOR WASTE HEAT UTILISATION.

Author(s) : GROSSMAN G., PEREZ BLANCO H.

Summary

THIS PAPER DESCRIBES THE CONCEPTUAL DESIGN OF A DOUBLE-STAGE ABSORPTION HEAT PUMP. THE HEAT PUMP IS DESIGNED TO UPGRADE WASTE HEAT OF LOW TEMPERATURE BY BOOSTING ITS TEMPERATURE TYPICALLY FROM 333 K (60 DEG C) TO 393 K (120 DEG C). THE SYSTEM USES PART OF THE LOW TEMPERATURE HEAT AS ITS ENERGY SOURCE AND REQUIRES NO PRIMARY ENERGY, EXCEPT FOR SMALL AUXILIARY EQUIPMENT. THE HEAT PUMP EMPLOYS AN ABSORBER/EVAPORATOR COMBINATION IN WHICH SOME HOT WATER FROM THE HEAT SOURCE IS EVAPORATED AND THE VAPOR ABSORBED IN A CONCENTRATED ABSORBENT SOLUTION. TWO STAGES OF THE ABOVE SYSTEM ARE USED IN SERIES TO PROVIDE THE DESIRED TEMPERATURE BOOST. THE PAPER DESCRIBES THE OPERATION OF THE SYSTEM AND DEFINES ITS PERFORMANCE CRITERIA. THE RESULTS OF A COMPUTER STUDY SHOW THE VARIATION IN PERFORMANCE WITH DIFFERENT DESIGN VARIABLES. TWO WORKING MATERIALS, LITHIUM BROMIDE-WATER AND LITHIUM CHLORIDE-WATER ARE CONSIDERED.
