What is the advantage to use a multistage compression refrigeration system over a single stage compression system?

the advantages of using multistage compression refrigeration system over a single stage compression system are as follows:

Explanation:

It results in increased volumetric efficiency of compressor due to decrease in pressure ratio in each stage. Cost of operation is comparatively low Uniformity in torque is achieved thus reducing the size of the flywheel. Reduced size of condensor as a result of heat removal during condensation Lower temperature at the end of compression resulting in effective lubrication and increased compressor life.
