Summary

USING DESICCANT-IMPREGNATED ROTARY HEAT EXCHANGERS, PRIMARY AIR FOR A FAN INDUCTION AIR-CONDITIONING SYSTEM CAN BE REDUCED TO A VERY LOW MOISTURE CONTENT. IF THIS IS THEN PUT THROUGH AN AIR WASHER, SATURATED AIR AS LOW AS 277.5 K (4.4 DEG C) CAN BE SUPPLIED. THE QUANTITY REQUIRED IS LIMITED ONLY BY FRESH AIR REQUIREMENTS AND IS USUALLY LESS THAN IN NORMAL INDUCTION SYSTEMS. SUCH A SYSTEM IS COMPARED WITH A NORMAL FAN INDUCTION SYSTEM AND ALSO A STANDARD VAV SYSTEM. THE COMPARISON IS BLURRED BY THE FACT THAT THE FIRST SYSTEM USES A GAS-ENGINE DRIVEN CHILLER WITH HEAT RECOVERY, WHILE THE SECOND USES ELECTRIC DRIVE AND AN ICE THERMAL STORAGE SYSTEM. THE FIRST SYSTEM SHOWS CONSIDERABLE COST SAVINGS IN MOST SCENARIOS. D.W.H.
