In primary pump systems without a bypass valve, we can use a variable frequency drive (VFD) to control the pump speed.
Use a variable frequency drive (VFD) to adjust the speed of the pump based on system demand
VFDs can help maintain system pressure and flow without the need for a bypass valve
VFDs can also improve energy efficiency by matching pump speed to actual system requirements
Types of chiller operating modes include constant speed, variable speed, and hybrid mode.
Constant speed mode: Chiller operates at a fixed speed regardless of load.
Variable speed mode: Chiller adjusts speed based on load requirements for energy efficiency.
Hybrid mode: Combines constant and variable speed modes for optimal performance.
Examples: Centrifugal chillers often operate in variable speed mode for energy savings.
