### Asset Description:
CRAC: Computer Room Air Conditioning: A type of air conditioning system specifically designed for cooling computer rooms and data centers. It is designed to maintain a specific temperature and humidity range to ensure the proper functioning of computer equipment.

### Conditions:
- Temperature Setpoint < 65 °F
- Supply Air Temperature - Temperature Setpoint > 3 °F

### How long the conditions were met:
Met for 3 Hours

What underlying factor, as presented in the options, could explain the current asset state?
A. Check condition of the filters
B. Too much equipment in the local area
C. Belt slipping or off
D. Too many CRAC units are running for the amount of load


# Answer
Answer: B. Too much equipment in the local area

Guidance Rationale: 
Given that the CRAC unit is designed to maintain a specific temperature and
humidity range for optimal computer equipment functioning, the conditions
indicate that the supply air temperature is significantly higher than the
temperature setpoint, which is below 65 °F. This discrepancy has persisted for 3
hours, suggesting that the cooling capacity of the CRAC unit is insufficient to
meet the current demand. 

While checking the condition of the filters (Option A)
is a routine maintenance task that could affect airflow, it is less likely to
cause such a significant and prolonged temperature discrepancy unless the
filters are severely clogged. The issue of a belt slipping or being off (Option
C) would typically result in no airflow at all, which is not indicated by the
given conditions. Having too many CRAC units running for the amount of load
(Option D) would likely lead to overcooling rather than the observed
undercooling. Therefore, the most plausible explanation for the current asset
state is that there is too much equipment in the local area (Option B),
overwhelming the CRAC unit's cooling capacity.
