DESIGN AND PERFORMANCE OF ZEOLITE-WATER HEAT PUMPS.

Author(s) : ROTHM EYER M., MAIER-LAXHUBER P., ALEFELD G.

Summary

SEVERAL HEAT PUMP SYSTEMS USING ZEOLITE AS ADSORBENT AND WATER AS ADSORBED GAS WERE BUILT AND TESTED. THE TESTS WERE CARRIED OUT ON A SYSTEM INCLUDING TWO MODULES FILLED WITH A TOTAL OF 800 KG ZEOLITE. THE STORAGE CAPACITY IS ABOUT 250 KILOWH FOR DOMESTIC HEATING, THE CAPACITY 20 KILOW. WITH A MAXIMUM CHARGING TEMPERATURE OF 573 K (300 DEG C) THE OUTLET TEMPERATURE MAY REACH 373 K (100 DEG C) WHEN THE HEAT SOURCE (AMBIENT) IS AT ABOUT 273 K (0 DEG C). THE COP RANGED BETWEEN 1.3 AND 1.4 FOR HEATING TEMPERATURES OF 353 AND 333 K (80 AND 60 DEG C), RESPECTIVELY.
