ESCO Air Conditioning Practice Exam

The temperature at which moisture will start to condense from the air is called

1. Dew point temperature

2. Humidity level temperature

3. Saturation temperature

4. Wet bulb temperature

The correct answer is: Dew point temperature

The correct answer is "A. Dew point temperature" because the dew point temperature is the specific temperature at which air becomes saturated with moisture and begins to condense into water. This process occurs when the temperature drops to the point where the air can no longer hold all of its water vapor, resulting in the formation of dew. The dew point temperature is a crucial parameter in air conditioning and refrigeration systems as it helps determine the potential for condensation and the level of humidity in the air. Option B, "Humidity level temperature," is not a commonly used term in the context of air conditioning and does not accurately describe the temperature at which moisture starts to condense from the air. Option C, "Saturation temperature," refers to the temperature at which a liquid and its vapor can coexist in equilibrium and is not specifically related to the condensation of moisture from the air. Option D, "Wet bulb temperature," is a measure of the lowest temperature that can be obtained by evaporating water into the air at a constant pressure. While wet bulb temperature is important in evaluating air properties, it is not the temperature at which moisture will start to condense from the air.
