- 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
- 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.
