6.1.6. Cooling and Dehumidifying

Try these first

1. 1.

   What does DBT stand for in air conditioning?

   Hint

   Think about how we measure air temperature.

2. 2.

   What process removes moisture from the air?

   Hint

   It’s key to reducing humidity.

3. 3.

   What does WBT stand for?

   • Wet Bulb Temperature
   • Water Bulb Temperature
   • Wind Bulb Temperature

   Hint

   It involves moisture in the air.

4. 4.

   True or False: Dehumidification can occur without cooling.

   • True
   • False

   Hint

   Consider how moisture collects in cooler air.

5. 5.

   A bakery operates at a relative humidity of 85% with an air temperature of 30°C. Calculate the dew point temperature.

   Hint

   Refer to psychrometric statistical tools or guidances.

6. 6.

   Design a minor air conditioning plan for a small office space of 1000 sq ft requiring a temperature of 22°C and RH of 50%. Explain the cooling and dehumidifying calculations.

   Hint

   Use principles like sensible heat and moisture content in air conditioning standards.
