Which of the following is an example of baseline condenser data used in energy efficiency assessments?

• A. Temperature of Air In
• B. Facade Color
• C. Power Outlet Location
• D. Door Swing Direction

Answer: (A)

Baseline data for condenser energy assessments are the initial operating conditions used to establish a reference point for performance. The temperature of air entering the condenser is a prime example because it directly sets how hard the condenser must work to reject heat. Cooler incoming air improves heat rejection, lowering compressor head pressure and energy use; hotter incoming air makes the condenser work harder and increases energy consumption. The other items don’t reflect condenser performance data: facade color affects building heat gain, and neither power outlet location nor door swing direction provides a direct measure of condenser operation or energy efficiency.
