2.1.1. Dry Bulb Temperature (DBT)

Try these first

1. 1.

   Define Dry Bulb Temperature (DBT).

   Hint

   Think about what temperature means in everyday life.

2. 2.

   What does Wet Bulb Temperature (WBT) indicate?

   Hint

   Consider evaporation effects.

3. 3.

   What does Dry Bulb Temperature measure?

   • Humidity in the air
   • Ordinary air temperature
   • Cooling effect

   Hint

   Think about how temperature is generally recorded.

4. 4.

   True or False: Wet Bulb Temperature is influenced by moisture content.

   • True
   • False

   Hint

   Consider the effect of evaporation.

5. 5.

   An HVAC system is designed for a room with a target DBT of 22°C. During a heat wave, the outside DBT soars, causing the system's efficiency to decline. Describe the potential strategies to maintain comfort.

   Hint

   Think about how outside conditions affect indoor temperature.

6. 6.

   Given a psychrometric chart, calculate the DBT and other related properties if the Wet Bulb Temperature is known to be 18°C and Relative Humidity is at 75%.

   Hint

   Recall how the properties interact in the chart.
