Answer :
Final answer:
Recovery in refrigeration involves removing refrigerant for storage, with re-liquefaction differing in vapor compression and vapor absorption systems due to distinct methods. Energy sources like electricity and heat aid in the re-liquefaction process.
Explanation:
Recovery in refrigeration systems involves the process of removing refrigerant in any condition from a system and storing it in an external container. This is crucial for maintaining and reusing the refrigerant efficiently.
Re-liquefaction methods differ between vapor compression and vapor absorption systems. In vapor compression systems, re-liquefaction is achieved by compressing the refrigerant to a liquid state, while in vapor absorption systems, it involves dissolving the refrigerant in a solvent and then separating and cooling it.
Energy sources such as electricity for compressors in vapor compression systems and heat for separating refrigerant in vapor absorption systems play key roles in the re-liquefaction process to keep the refrigeration systems functioning effectively.
