2. Working Principle and Basic Components

Try these first

1. 1.

   What is the role of the evaporator in VARS?

   Hint

   Think about what happens first in the refrigeration cycle.

2. 2.

   Name a key component that separates refrigerant vapor from absorbent.

   Hint

   This component applies heat.

3. 3.

   What is the primary purpose of the generator in VARS?

   • To absorb refrigerant
   • To separate refrigerant vapor
   • To cool the environment

   Hint

   It involves adding heat to the system.

4. 4.

   True or False: The absorber releases heat when absorbing vaporized refrigerant.

   • True
   • False

   Hint

   Consider what happens in an absorption process.

5. 5.

   Design a simple VARS layout suitable for an industrial setting using waste heat. Explain your choices for each component.

   Hint

   Think about the paths each component will take.

6. 6.

   Evaluate the implications of utilizing ammonia as a refrigerant in VARS in regard to safety and efficiency.

   Hint

   Consider both environmental and operational factors.
