LARGE HEAT PUMPS IN DISTRICT HEATING NETWORKS.

Author(s) : ENSTROM H., KARSTROM A., SOLIN L.

Summary

IN SWEDEN, AT THE BEGINNING OF 1987, THERE WERE ABOUT ONE HUNDRED HEAT PUMPS OF MORE THAN 1 MEGAWATT SERVING DISTRICT NETWORKS. THEIR OVERALL HEATING CAPACITY IS HIGHER THAN 1,200 MEGAWATT AND THE THERMAL ENERGY DELIVERED IS 6 TO 7 TERAWATTHOUR/YEAR. FOUR PLANTS WERE SUBJECTED TO A CAMPAIGN OF MEASUREMENT. TWO OF THEM TAKE THE HEAT OF WASTE WATER, ONE OF SEA WATER AND THE FOURTH ONE COMBINES BOTH SOURCES. THE LAST ONE USES SCREW COMPRESSORS, WHEREAS THE OTHERS HAVE CENTRIFUGAL COMPRESSORS. THE RESULTS ARE SUBSTANTIALLY POSITIVE, BOTH TECHNICALLY AND ECONOMICALLY. THE AUTHORS PRESENT THE PERFORMANCE OF THE PLANT AND TEST RESULTS.
