ShareCONTROL OF VARIABLE-SPEED PUMPS ON HOT- AND CHILLED-WATER SYSTEMS.
Author(s) : RISHEL J. B.
Summary
THE CONTROL OF VARIABLE-SPEED PUMPS ON HOT-AND CHILLED-WATER SYSTEMS MUST BE BASED UPON A HYDRAULIC ANALYSIS OF THE WATER SYSTEM. UNIT RESPONSIBILITY IS SECURED BY REQUIRING THE CONTROL MANUFACTURER TO FURNISH THE VARIABLE-SPEED DRIVES. CONTROL OF THESE PUMPS IS ACHIEVED THROUGH THE USE OF DIFFERENTIAL PRESSURE TRANSMITTERS AND CONTINUOUS INTERROGATION OF THEM ; THIS ELIMINATES SYSTEM HUNTING, CONTINUOUS VARIATION IN PUMP SPEED, AND INEFFICIENT PUMP OPERATION.
