If condensation collects and drips off an evaporator coil, what best describes the operating temperature of the coil?

🔍 Key Concepts

• Dew point: the temperature at which air becomes saturated and water vapor starts to condense. • Relationship between freezing point (32°F) and whether water appears as liquid droplets or ice. • How an evaporator coil in a refrigeration/AC system causes moisture to condense from the air.

💭 Think About

• If water is forming as liquid droplets and dripping, what does that tell you about whether the coil surface is above or below 32°F? • For condensation to occur, how must the coil temperature compare to the dew point of the surrounding air? • Think about what would happen (ice vs. dripping water) if the coil were much colder than freezing compared to just slightly colder than the dew point.

✅ Before You Answer

• Confirm whether liquid water dripping (not ice) can exist on a surface below 32°F in normal conditions. • Confirm that condensation starts when a surface is cooled below the dew point of the surrounding air. • Check each answer for consistency with both: (1) liquid water dripping, and (2) the basic definition of dew point.

If condensation collects and drips off an evaporator coil, what best describes the operating temperature of the coil?

it is at a maximum of 21°F

it is above 32°F, but below the dew point

it is at 21°F but, above the dew point

it is below 32°F and below the dew point
