Parts of a Refrigerator

There are not too many homes that don’t have a refrigerator inside the kitchen. It’s been a must-own appliance for several years now. A household refrigerator will store your food at the best temperature, to eliminate rotting and slow down the growth of bacteria. The cycle of refrigeration works by moving the heat from the interior of the refrigerator to the exterior, using the principles of condensation and evaporation.

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


The compressor is both a motor and pump, and it is necessary for the circulation of refrigerant in the cooling system.
A compressor is a very important piece of a refrigerator. You should enlist a professional company if the compressor is broken.


The refrigerator condenser is attached on the back outside wall of the appliance and will help to emit the warmth built-up within the refrigerator out in the air.


The evaporator is installed on the inside of a refrigerator where it absorbs the heat contained inside of it, effectively lowering the temperature inside.

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

Expansion Device

Liquid refrigerant is directed within a capillary tube that serves as an expansion device to cool the gas inside, turning it back into liquid.


The thermostat will regulate the temperature inside a refrigerator, beginning a new cooling period when appropriate.

The thermostat inside of a refrigerator is often prone to issues. Troubleshoot and hire a contractor in CITY for service right after a problem occurs.

How Does Refrigeration Work?

1. Right when the temperature within a refrigerator goes above the set point sensors notify the compressor to engage, and the next cooling cycle begins. The unit attracts the cool liquified refrigerant, then pressurizes and condenses the liquid, and raises the temperature, so it can turn into a gas.

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

3. The cooled liquified gas then continues on its trip towards the refrigerator evaporator component, pushing through the coils in the inside of the appliance and freezer.

4. The liquid then absorbs the hot air from the interior of the refrigerator, thereby reducing the temperature until it has reached the desired set point.

5. The refrigerant then will evaporate, and will turn back to a gas form, and then returns to the compressor unit so it can continue the cycle.

Refrigeration technology is used in several applications and household appliances, this includes heat pumps, AC units, refrigerators and freezers. By extracting warmth from a single place and relocating it to another the cycle of refrigeration contributes in cooling a home, provides a perfect environment for food that is perishable, and also helps with the manufacturing and storage of many different everyday products and goods.
