The major parts of a refrigerator

The major parts of a refrigerator are:

4

1. Compressor – Compresses and circulates the refrigerant through the cooling system.
2. Condenser – Releases heat from the refrigerant to the surrounding air.
3. Filter drier – Removes moisture and dirt from the refrigerant.
4. Capillary tube – Reduces the refrigerant pressure and controls its flow into the evaporator.
5. Evaporator – Absorbs heat from inside the refrigerator, producing cooling.
6. Thermostat – Controls the compressor to maintain the desired temperature.
7. Refrigerant (gas) – Carries heat through the refrigeration system.
8. Condenser fan (on many frost-free models) – Cools the condenser coils.
9. Evaporator fan (on frost-free models) – Circulates cold air throughout the refrigerator.
10. Defrost system (in frost-free refrigerators) – Includes the defrost heater, defrost thermostat, and defrost timer or electronic control board to remove frost from the evaporator.

In simple terms, the cooling cycle is:

• Compressor → pumps the refrigerant.
• Condenser → removes heat.
• Filter drier → cleans and dries the refrigerant.
• Capillary tube → lowers the refrigerant pressure.
• Evaporator → absorbs heat from inside the fridge, making it cold.
• Thermostat → controls when the compressor turns on and off.

These are the main components that allow a refrigerator to cool food efficiently.
