6.1. Components and Functions

Try these first

1. 1.

   What is the main function of the absorber in a VARS?

   Hint

   Think about what happens to refrigerants in a cooling system.

2. 2.

   Name one advantage of using Lithium Bromide in refrigeration.

   Hint

   Consider safety in comparison to ammonia.

3. 3.

   What is the role of the generator in a VARS?

   • Separation of refrigerant from absorbent
   • Pumping solutions
   • Heat absorption

   Hint

   Think about what happens during the heating process.

4. 4.

   True or False: Lithium Bromide is used in applications requiring freezing temperatures.

   • True
   • False

   Hint

   Recall the properties of different absorbents.

5. 5.

   Design a VARS system for a remote facility using waste heat. Identify suitable refrigerant-absorbent pairs and justify your choices.

   Hint

   Consider the operational environment of the facility when selecting materials.

6. 6.

   Discuss the advantages and disadvantages of using the LiBr-water system over the NH₃-H₂O system in air conditioning applications.

   Hint

   Compare their application contexts to draw conclusions.
