Which datum would be considered baseline when comparing condenser efficiency over time?

• A. Temperature of Air In
• B. VOC Level in Room
• C. Lighting Level
• D. Duct Airflow Velocity

Answer: (A)

The key idea is that condenser efficiency hinges on the temperature of the air that is entering the condenser to reject heat. Establishing a baseline for the air entering the condenser during normal operation gives you a fixed reference to compare future performance against, so you can tell whether any changes are due to the condenser itself (like fouling or worn fans) rather than just a warmer or cooler environment. The other data points don’t directly measure the condenser’s ability to reject heat: indoor VOC levels affect air quality, lighting level is unrelated to heat rejection, and duct airflow velocity affects distribution but not the condenser’s heat rejection performance itself.
