You won’t find many houses that don’t have a refrigerator inside the kitchen. It’s been a standard household appliance for several years. A household refrigerator stores your food at the best temperature, to stop spoiling and stop bacteria. The cycle of refrigeration starts by moving the warmth from inside of the unit to the exterior, by relying on principles of evaporation and condensation.

The components of your refrigerator are. For questions or service call Duncan Appliance Repair:


The refrigerator compressor is a combination of a motor and a pump, and it is need for the circulation of refrigerant throughout the cooling system.
The compressor is an integral part of a refrigerator. Homeowners should enlist a professional company if the compressor isn’t working.


A condenser is attached on the back outside panel of the appliance and is there to release the heat collected within the refrigerator out in the air.


The refrigerator evaporator is located on the inside of a refrigerator where absorbs heat held within it, thereby reducing the interior temperature.

Right when an evaporator is not working, it’s time to find a professional. Do not wait too long.

Expansion Device

The refrigerator thermostat regulates the temperature inside the refrigerator, starting the cooling cycle as necessary.

How Does Refrigeration Work?

1. Once the temperature in the interior of the refrigerator rises higher than the set point sensors alert the compressor to engage, and the next cool down begins. The unit collects the cool liquified refrigerant, then pressurizes and condenses the refrigerant, and increases the temperature, so it can turn into a gas.

2. The compressor unit directs the hot gas in the direction of the refrigerator condenser coils located on the exterior of the unit, at which point it comes in contact with warmer temperature in the kitchen and reverts back to a liquified form.

3. The cool refrigerant continues its trip to the refrigerator evaporator, pushing through the coils within the refrigerator and top freezer.

4. The liquid then absorbs the warm air from within the appliance, reducing the temperature until it has reached the best set point.

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

Refrigeration is often used in quite a few applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By contracting warmth from one location and moving it to somewhere else the continuous cycle of refrigeration contributes in cooling your house, provides a perfect environment for perishable food, and also helps with manufacturing and storage of a lot of different common products and goods.
