IIR documentSummary
THE PAPER PRESENTS THE DESIGN AND RESULTS OF A COMPRESSION HEAT PUMP WITH SOLUTION CIRCUIT. THE HEAT PUMP OFFERS TWO MAJOR ADVANTAGES OVER A SINGLE FLUID RANKINE CYCLE: 1, THE HEATING CAPACITY IS VARIED BY A LARGE FACTOR BY ADJUSTING THE COMPOSITION OF THE MIXTURE ; AND 2, THE APPROXIMATION OF T LORENZ PROCESS ALLOWS FOR SUBSTANTIALLY HIGH COP VALUES IN CASES WITH GLIDING TEMPERATURES. THE TEST PLANT HEATS WATER FROM 313 TO 343 K (40 TO 70 DEG C) AND COOLS WATER FROM 313 TO 288 K (40 TO 15 DEG C). A COP OF 4.3 WAS MEASURED, REPRESENTING AN ENERGY SAVING OF 23%, COMPARED WITH A GOOD SINGLE FLUID RANKINE CYCLE.
