An example of baseline condenser data is which temperature value?

• A. Temperature of Air In
• B. Ambient Humidity
• C. Compressor Discharge Temperature
• D. Condenser Outlet Pressure

Answer: (A)

The concept being tested is how ambient conditions set the baseline for condenser performance. The temperature of the air entering the condenser is a key baseline value because it represents the external heat-rejection environment the condenser must overcome. A higher inlet air temperature reduces the temperature difference between the refrigerant and the air, lowering heat transfer efficiency and affecting condenser pressure and overall capacity. This is why an example of baseline condenser data is the air entering temperature.

The other options don’t fit as temperature baselines for condenser data: ambient humidity is not a temperature, compressor discharge temperature is a system-operating value that varies with load, and condenser outlet pressure is a pressure, not a temperature.
