5.5. Limitations

Try these first

1. 1.

   What is the main refrigerant in the Water-Ammonia absorption system?

   Hint

   Look for the pairing of refrigerants.

2. 2.

   What is a significant issue regarding Lithium Bromide's operation?

   Hint

   Think about temperature ranges and concentrations.

3. 3.

   What is the main limitation of the Water-Ammonia absorption system?

   • High energy consumption
   • Water carryover
   • Inefficient heat transfer

   Hint

   Think about liquid transfer issues.

4. 4.

   True or False: Lithium Bromide can achieve freezing temperatures in refrigeration applications.

   • True
   • False

   Hint

   Recall the operational limits.

5. 5.

   Design a hypothetical VARS for a low-temperature application, addressing the limitations of both Water-Ammonia and Water-Lithium Bromide systems.

   Hint

   Consider the pros and cons of each system.

6. 6.

   Analyze how a specific application, like solar-powered refrigeration, would handle the limitations presented in a Vapor Absorption Refrigeration System.

   Hint

   Consider environmental conditions and energy sources.
