How Does Refrigeration Work?

1. When the temperature in the interior of a refrigerator goes higher than the set point sensors signal the refrigerator compressor to start, and then the cool down starts. The unit draws in the cold liquified refrigerant, then pressurizes and condenses the liquid, and raises the temperature, so it can turn into a gas.

2. The compressor unit directs the warm gas in the direction of the condenser coils located on the outside of the appliance, where it comes into contact with warmer air temperature in the room and returns back to a liquid state.

3. The cooled refrigerant then continues its journey to the refrigerator evaporator, pushing through the coils in the inside of the appliance and top freezer compartment.

4. The refrigerant absorbs the warm air from the interior of the refrigerator, cooling the temperature until it has reached the best set point.

5. The coolant then evaporates, and turns back into a gas state, and then returns to the refrigerator compressor unit to continue the cycle.

Refrigeration is often found in a number of applications and household appliances, this includes heat pumps, AC units, refrigerators and freezers. By removing heat from one place and moving it to a different one the cycle of refrigeration will help cooling your home, provides a perfect environment for food that is perishable, and helps with manufacturing and storage of many different common products and goods.
