Parts of a Refrigerator

There aren’t many houses that do not have a refrigerator in the kitchen. It’s been a must-own kitchen appliance for several years now. A refrigerator is able to store food and drinks at the best temperature, to reduce spoilage and limit bacteria. The concept of refrigeration starts by transferring the heat from the interior of the appliance to the exterior, relying on the principles of evaporation and condensation.

The components of a refrigerator are. For questions or service call Noble Norfolk Appliance Repair:


A compressor is both a motor and a pump, and it is responsible for the circulation of refrigerant dispersed in the cooling system.
The compressor is a very important piece of a refrigerator. You should call a professional service if the compressor is not working.


The refrigerator condenser is located on the back exterior wall of the refrigerator and will help to release the heat absorbed inside the refrigerator then out to the air.


The evaporator is located on the inside of the refrigerator where it absorbs the warmth held inside of it, effectively reducing the temperature inside the refrigerator.

Once the evaporator is not working, it is time to hire a professional. You should not wait until it’s too late.

Expansion Device

Liquified refrigerant is transferred through a capillary tube that works as an expansion device to cool the gas inside, turning the gas into a liquid.


The refrigerator thermostat regulates the current temperature throughout the refrigerator, beginning a new cooling period as necessary.

The thermostat in a refrigerator is prone to problems. Troubleshoot and hire a technician in Norfolk for service right when a problem happens.

How Does Refrigeration Work?

1. When the temperature inside the refrigerator rises higher than the set point sensors signal the compressor to begin, and then the next cool down begins. The unit draws in the cool liquid refrigerant, condenses and pressurizes the liquid, and raises the temperature, in order to turn it into a gas.

2. The compressor guides the heated gas in the direction of the refrigerator condenser coils on the exterior of the refrigerator, where it comes in contact with the lower temperature in the kitchen and reverts back to a liquid state.

3. The cooled liquid then continues its trip to the evaporator, finding its way through the many coils within the appliance and freezer compartment.

4. The liquid then absorbs the heated air from inside the appliance, lowering the temperature back to the desired final point.

5. The liquid then evaporates, and turns back into a gas, and then returns to the refrigerator compressor to then continue the cooling cycle.

Refrigeration technology is often used in quite a few applications and large appliances, this includes heat pumps, AC units, refrigerators and freezers. By removing warmth from one location and distributing it to a different one the cycle of refrigeration aids in cooling your home, creates a perfect environment for food that is perishable, and helps with manufacturing and storage of a lot of different common products and materials.
