Which parameter is an example of baseline condenser data?

• A. Temperature of Air In
• B. Discharge Line Color
• C. Oil Viscosity
• D. Suction Pressure

Answer: (A)

Baseline condenser data are the steady measurements kept as a reference during normal operation. The condenser’s job is to reject heat from the refrigerant to the surrounding air, so the most informative starting point is the air entering the condenser. The temperature of that incoming air directly affects how much heat the condenser can remove and helps set the expected operating pressures and temperatures. In other words, it defines the driving force for heat transfer and serves as a reliable reference point for performance checks.

Discharge line color has no bearing on operating performance; it’s an appearance factor, not a performance parameter. Oil viscosity matters for lubrication and compressor wear, not for condenser heat rejection. Suction pressure pertains to the evaporator/compressor side of the system, not the condenser’s baseline operating conditions.
