INSTALLATION OF VFDS ON CONDENSER WATER PUMP MOTORS TO ACHIEVE VARIABLE CONDENSER WATER FLOW

摘要

A properly implemented variable condenser water pumping system is an affordable addition to any energy retrofit, central plant renovation, or new construction project. In a retrofit project, existing conditions, such as chiller unloading capability, condenser water, and cooling tower control, need to be carefully examined to ensure the system will function properly following the retrofit. In new construction, care must be taken during chiller and cooling tower equipment selection. Finally, the implementation of variable condenser water flow should be considered only if variable chilled water flow and variable speed cooling tower fans are present or are in rhe pipeline for construction.
