Parts of a Refrigerator

There are not many houses that don’t feature a refrigerator inside the kitchen. It’s been a must-have appliance for a lot of years. A refrigerator stores your food and drinks at the optimal temperature, in order to reduce spoiling and stop the growth of bacteria. The concept of refrigeration starts by moving the heat from inside of the appliance to the exterior, by relying on the principles of evaporation and condensation.

A refrigerator compressor is a combo of a pump and motor, and it’s need for circulation of refrigerant throughout the system.
A compressor is an integral part of a refrigerator. You should hire a professional service if the compressor isn’t working.


The refrigerator condenser is located on the rear outside panel of the refrigerator and is there to disperse the heat built-up from inside the refrigerator out in the air.


A refrigerator evaporator is stored on the inside of a refrigerator where absorbs warmth contained inside of it, thereby reducing the interior temperature.

The moment the evaporator stops working, it’s time to call a professional. Do not wait too long.

Expansion Device

Liquid coolant is transferred within a capillary tube which works as an expansion device as it cools the gas inside, transforming the gas into a liquid.


The thermostat regulates the temperature within the refrigerator, engaging a new cooling cycle as required.

The thermostat inside of a refrigerator is prone to issues. Troubleshoot and call a contractor in Centreville for repair right after a problem occurs.

How Does Refrigeration Work?

1. Right when the temperature within a refrigerator rises higher than the set point sensors alert the refrigerator compressor to start, and the cool down starts. The unit attracts the cool liquid refrigerant, pressurizes and condenses the liquid, and increases the temperature, turning it into a gas.

2. The refrigerator compressor directs the hot gas in the direction of the refrigerator condenser coils located on the back of the unit, where it comes into contact with the lower temperature in the room and returns back to a liquid form.

3. The cool liquid continues its trip to the evaporator component, pushing through the coils within the refrigerator and freezer compartment.

4. The coolant absorbs the hot air from inside the refrigerator, thereby reducing the temperature until it has reached the desired final point.

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

Refrigeration is often used in several applications and appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from one place and then transferring it to elsewhere the cycle of refrigeration aids in cooling a house, provides a optimal storage space for food that is perishable, and helps with the manufacturing and storage of a number of different everyday products and materials.
