2. 2.

   Define psychrometry.

   Hint

   What does psychrometry focus on in terms of air?

3. 3.

   What is the main purpose of industrial air conditioning systems?

   • To improve human comfort
   • To maintain environmental conditions for processes
   • To provide heating only

   Hint

   Think about the settings these systems are typically used in.

4. 4.

   True or False: Comfort air conditioning is designed only for industrial use.

   • True
   • False

   Hint

5. 5.

   In a commercial building, the cooling load is to be calculated for a space of 2000 sqft. The cooling factor is 4, the lighting load is 8000 BTU/hr, and the occupancy is 25 people. Calculate the total cooling load.

   Hint

   Use the simplified formula introduced in class.

6. 6.

   You are designing an air-conditioning system for a laboratory with strict temperature controls. Describe how you would calculate the specific cooling load needed, and what factors would be considered.

   Hint

   What internal and external sources contribute to your calculations?
