3. Absorbent–Refrigerant Combinations

Try these first

1. 1.

   What is the primary refrigerant used in a Water-Lithium Bromide system?

   Hint

   Think about the name of the system.

2. 2.

   True or False: Ammonia is a safe refrigerant in all applications.

   Hint

   Consider ammonia's properties.

3. 3.

   What is the primary refrigerant used in Water-Lithium Bromide systems?

   • Water
   • Lithium Bromide
   • Ammonia

   Hint

   Which term indicates that it is primarily a salt?

4. 4.

   True or False: The Water-Ammonia system is preferred due to its efficiency.

   • True
   • False

   Hint

   Reflect on the properties of water.

5. 5.

   Consider a refrigeration application that requires low-temperature cooling. Which absorption system would you recommend and why?

   Hint

   Focus on the specific refrigerant qualities required for low temperatures.

6. 6.

   Evaluate the implications of using lithium bromide in a very cold environment where crystallization occurs.

   Hint

   Think about temperature effects on absorbent states of matter.
