### Asset Description:
Chiller: A device that removes heat from a liquid through a vapor-compression or vapor-absorption refrigeration process. The cooled liquid can then be used to cool equipment, buildings, or other systems.

### Conditions:
- Chiller Running
- Supply Temperature - Setpoint Temperature > 5 °F

### How long the conditions were met:
Met for 2 Hours

If you were to advise the operator, which option should they prioritize, based on the conditions?
A. Hand or overridden on when the supply fan is off
B. System is not designed well for part loads on the chiller
C. Check VAV box flow sensors
D. CRAC units that can be turned off to provide energy savings


# Answer

Answer: B. System is not designed well for part loads on the chiller

Guidance Rationale: Given that the chiller is running and the supply temperature exceeds the setpoint temperature by more than 5 °F,
persisting for 2 hours, it indicates that the chiller is not effectively meeting the cooling demand. This sustained discrepancy suggests that the system may not be adequately designed to handle part loads efficiently,
which can lead to inefficiencies and potential energy waste. 

Therefore, the operator should prioritize investigating and addressing the system's design for part-load performance
to ensure optimal cooling efficiency and energy usage.
