In a performance log, baseline condenser data is typically recorded as?

• A. Temperature of Air In
• B. Battery State of Charge
• C. Water pH
• D. Ventilation Rate

Answer: (A)

Condenser performance depends on the air that carries away the rejected heat. Recording the temperature of the air entering the condenser gives a consistent starting point to evaluate how effectively the condenser is rejecting heat under those conditions. This inlet-air baseline helps you interpret head pressure, cooling capacity, and overall efficiency, and it allows meaningful comparisons across tests or setups.

The other options don’t fit as baseline condenser data: battery state of charge is about energy storage components, not the condenser; water pH concerns water quality in water-cooled systems, not the air-side baseline; and ventilation rate matters, but without tying it to the actual inlet air temperature and flow, it doesn’t provide the direct baseline needed for condenser performance.
