4.1. Configuration

Try these first

1. 1.

   What is the main difference between VARS and conventional refrigeration systems?

   Hint

   Think about the source of energy for the cooling process.

2. 2.

   Name one component of a VARS.

   Hint

   Focus on the parts that help it operate.

3. 3.

   What is the main source of energy for Vapor Absorption Refrigeration Systems?

   • Electricity
   • Thermal energy
   • Mechanical energy

   Hint

   Think about the type of energy that is typically less refined.

4. 4.

   True or False: Water-Lithium Bromide systems can achieve freezing temperatures.

   • True
   • False

   Hint

   Consider the properties of the refrigerant used.

5. 5.

   Design a hypothetical VARS for a rural community that primarily relies on waste heat from a local manufacturing facility. What components would you include, and why?

   Hint

   Think about how local resources can influence component choice and design.

6. 6.

   Analyze the effect of water contamination in an ammonia-water absorption system. What steps can be implemented to mitigate this issue?

   Hint

   Consider technological solutions that allow for separation and purification in the system.
