1.2.1. Centrifugal Compressors

Try these first

1. 1.

   What role does an impeller play in a centrifugal compressor?

   Hint

   Think about how kinetic energy is generated.

2. 2.

   Name one advantage of using centrifugal compressors.

   Hint

   Consider the noise levels and maintenance.

3. 3.

   What is the primary function of a centrifugal compressor?

   • Increase pressure by decreasing volume
   • Increase pressure by increasing velocity
   • Decrease temperature

   Hint

   Think about how kinetic energy is transformed.

4. 4.

   Are centrifugal compressors effective at low capacities?

   • Yes
   • No

   Hint

   Consider performance metrics under varying loads.

5. 5.

   Design a small HVAC system for a residential building that uses centrifugal compressors. Discuss the advantages and potential issues you might face.

   Hint

   Consider the size and purpose of the building when determining ideal compressor capacity.

6. 6.

   Research the thermodynamic properties of two different refrigerants and explain how these properties affect their suitability in centrifugal compressors.

   Hint

   Look for resources comparing different refrigerants' performance metrics.
