Working of a Refrigerator

A refrigerator works by passing a cool refrigerant gas around food items (kept inside the fridge), which absorbs heat from them and then loses that heat to the relatively cooler surroundings on the outside.

In the refrigeration cycle, there are five basic components which helps Refrigerator for cooling.
1- Compressor

The compressor constricts the refrigerant vapor, raising its pressure and temperature, and pushes it into the coils of the condenser on the outside of the refrigerator.
2 - Fluid Refrigerant

Fluid refrigeration is an system which does not needs any mechanical work or electrical works(no pump or compressor).

3 - Condenser Coils

These coils are very important in the cooling process because they allow the highly pressurized and heated refrigerants to get cooled. This is the reason why the refrigerator condenser coils are usually warm.

4 - Evaporator Coils

The evaporator coil is the component in an air conditioner or heat pump that is responsible for the cooling of a home.
The evaporator reduces the temperature but does not actually make anything cold.

5 - Expansion Valve

The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator
