  • Q3. What to we use in primary pump systems if we don't have bypass valve
  • Ans. 

    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

  • Answered by AI
  • Q4. Types of chiller operating mode
  • Ans. 

    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.
