How Does Refrigeration Work?

1. Once the temperature inside a refrigerator rises above the set point sensors notify the compressor to start, and then the next cool down begins. The appliance draws in the cool liquified refrigerant, then pressurizes and condenses the refrigerant, and raises the temperature, turning it into a gas form.

2. The refrigerator compressor unit pushes the warm gas towards the refrigerator condenser coils on the outside of the appliance, where it comes into contact with warmer air temperature in the room and reverts to a liquified state.

3. The cooled refrigerant continues its trip to the refrigerator evaporator, making its way through the coils on the interior of the appliance and freezer.

4. The coolant then absorbs the heated air from the interior of the appliance, thereby reducing the temperature until it has reached the desired final point.

5. The liquid then will evaporate, and will turn back into a gas, and then returns to the refrigerator compressor unit to then continue the cycle.

Refrigeration is often used in quite a few applications and appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By extracting warmth from one area and then moving it to elsewhere the continuous cycle of refrigeration helps cooling your home, provides a safe environment for perishable food, and also helps with the manufacturing and storage of a lot of different common products and goods.
