The thermostat regulates the temperature within the refrigerator, engaging a new cooling period when it is needed.

How Does Refrigeration Work?

1. When the temperature within the refrigerator goes above the set point sensors notify the compressor to start, and then the next cool down begins. The refrigerator draws in the cool liquid refrigerant, then pressurizes and condenses the refrigerant, and increases the temperature, so it can turn into a gas.

2. The compressor directs the heated gas in the direction of the refrigerator condenser coils on the back of the unit, at which point it comes into contact with the lower temperature in the room and returns back to a liquid state.

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

4. The refrigerant absorbs the hot air from within the appliance, thereby cooling the temperature back to the optimal final point.

5. The liquid will evaporate, and turns back into a gas state, and returns to the refrigerator compressor in order to then continue the cycle.

Refrigeration is often used in many applications and household appliances, including heat pumps, air conditioners, refrigerators and freezers. By removing heat from a single area and then moving it to another the continuous cycle of refrigeration contributes in cooling a home, provides a optimal space for food that is perishable, and also helps with the manufacturing and storage of a number of different everyday products and materials.
