Parts of a Refrigerator

There aren’t too many homes that don’t have a refrigerator in the kitchen. It’s been a standard household appliance for several years now. A household refrigerator stores food and drinks at the right temperature, to prevent spoiling and limit the growth of harmful bacteria. The process of refrigeration starts by distributing the warmth from inside of the unit to the outside, by relying on the principles of evaporation and condensation.

The standard components of a refrigerator are. For questions or service call Evans Appliance Repair:


The compressor is both a pump and a motor, and it is necessary for circulation of refrigerant in the system.
A compressor is an important part of a refrigerator. Homeowners should hire a professional service if the compressor is not working.


A condenser is attached on the back outside wall of the refrigerator and helps to emit the heat absorbed inside the refrigerator out in the surrounding air.


The refrigerator evaporator is attached in the inside of the refrigerator where absorbs heat contained within it, thereby reducing the temperature inside the unit.

Once the evaporator stops working, it is time to find a professional. Don’t wait until it is too late.

Expansion Device

Liquid coolant is transported through a capillary tube that works as an expansion device as it cools the gas inside, transforming it into liquid.


A thermostat regulates the temperature in the interior of the refrigerator, engaging the cooling period when required.

The thermostat in a refrigerator is prone to issues. Troubleshoot and hire a repairman in New Jersey for repair the moment an issue occurs.

How Does Refrigeration Work?

1. The moment the temperature in the interior of the refrigerator rises higher than the set point sensors notify the compressor to engage, and the next cooling period begins. The unit draws in the cool liquid refrigerant, then condenses and pressurizes it, and increases the temperature, turning it into a gas form.

2. The compressor directs the heated gas in the direction of the refrigerator condenser coils on the rear of the refrigerator, at which point it comes in contact with warmer temperature in the kitchen and transforms back to a liquid state.

3. The cool refrigerant then continues on its trip to the refrigerator evaporator component, traveling through the coils on the inside of the appliance and top freezer compartment.

4. The liquid absorbs the heated air from the interior of the appliance, thereby returning the temperature until it has reached the best final point.

5. The coolant will evaporate, and will return back to a gas form, and then returns to the refrigerator compressor in order to then continue the cycle.

Refrigeration is used in a number of applications and appliances, including heat pumps, AC units, refrigerators and residential freezers. By contracting heat from a single area and then distributing it to a different one the continuous cycle of refrigeration helps cooling a house, provides a perfect space for perishable food, and helps with the manufacturing and storage of many different products and materials.
