Question

Explain the mechanism of a refrigerator with the help of a schematic diagram.

Answer 1

1. Mechanism of a refrigerator:
2. A refrigerator takes heat from a cold region (inside the chamber or compartments) and transfers it to the surrounding (atmosphere), thus cooling the cold region further.
3. The diagram depicts the mechanism utilised in a standard refrigerator. It is made up of a compressor, an expansion valve, and a closed tube that transports the refrigerant.
4. As a refrigerant, fluorinated hydrocarbons are utilised.
5. The cooling coil is a section of the tube that is in the region that will be cooled at a lower temperature and pressure.
6. The other section that is exposed to the outside world (usually, the atmosphere) has a higher temperature and pressure.
