In an absorption refrigeration system, the compressor of a vapor-compression system is replaced by:
- An absorber, pump and generator
- An expansion valve
- A condenser and receiver
- A turbine
Answer
A. An absorber, pump and generator
Solution
Absorption systems use heat (in the generator) instead of shaft work to raise refrigerant pressure; e.g., ammonia–water or lithium bromide–water.
