Step 1: Understanding the Concept:
Multi-compression systems use intercoolers.
They have specific functions in the cycle.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the function of an intercooler.
Step 3: Detailed Explanation:
An intercooler is used to desuperheat the vapour coming out of the compressor.
It cools the vapour between compression stages.
Flash chambers are used for flash gas removal.
Expansion valves reduce pressure.
Condensers reject heat.
Thus, the intercooler desuperheats the vapour.
Step 4: Final Answer:
The intercooler desuperheats the vapour.
Hence, the correct option is (B).
