Baseline condenser data includes what type of measurement?

Baseline condenser data includes what type of measurement?

• A. Temperature of Air In
• B. Refrigerant Color
• C. Cleaner Type Used
• D. Evaporator Coil Dirt Level

Answer: (A)

When establishing baseline condenser data, the key idea is to capture the starting conditions that show how well the condenser can reject heat. The most important measurement to record is the temperature of the air entering the condenser. This inlet air temperature directly affects the condenser’s ability to transfer heat from the refrigerant to the ambient air, influencing condensing pressure and overall efficiency. If the air entering is higher than expected, heat rejection worsens and pressures rise, reducing performance; if it’s within the expected range, the system is operating as designed. The other items aren’t baseline condenser measurements: refrigerant color isn’t a quantitative performance parameter, cleaner type used is a maintenance detail, and evaporator coil dirt level relates to the evaporator section rather than the condenser’s baseline performance.
