3.1.1. Air Temperature (DBT)

Try these first

1. 1.

   What does Dry Bulb Temperature (DBT) measure?

   Hint

   Think about what a regular thermometer reads.

2. 2.

   What is the ideal Relative Humidity (RH) range for comfort?

   Hint

   It's typically between 30% to 60%.

3. 3.

   What does Dry Bulb Temperature (DBT) measure?

   • Moisture content
   • Ordinary air temperature
   • Pressure of air

   Hint

   Think about what thermometer readings tell you.

4. 4.

   True or False: The comfort zone for DBT is typically between 15°C to 25°C.

   • True
   • False

   Hint

   Recall the range we discussed in class.

5. 5.

   If the outside temperature is recorded at 35°C and the DBT inside a room is at 23°C with 50% RH, determine if the room is comfortable for an average occupant.

   Hint

   Compare the values against known comfort standards.

6. 6.

   A system designed to maintain 22°C DBT and 55% RH in an office is operating inefficiently. What could be potential causes?

   Hint

   Consider all environmental factors influencing the HVAC system.
