Expansion Device

How Does Refrigeration Work?

1. Right when the temperature in the interior of the refrigerator is higher than the set point sensors alert the compressor to engage, and then the next cool down begins. The unit attracts the cold liquid refrigerant, then condenses and pressurizes the liquid, and increases the temperature, turning it into a gas form.
2. The compressor guides the warm gas towards the condenser coils located on the rear of the appliance, where it comes in contact with warmer air temperature in the room and reverts back to a liquid form.
3. The cooled refrigerant continues on its journey towards the evaporator, pushing through the coils within the refrigerator and top freezer compartment.
4. The liquid then absorbs the warm air from within the appliance, cooling the temperature back to the optimal set point.
5. The coolant will evaporate, and turns back into a gas, and returns to the compressor to then continue the cooling cycle.

Refrigeration is used in a number of applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By extracting warmth from one place and then transferring it to a different one the cycle of refrigeration helps cooling a home, provides a safe environment for food that is perishable, and helps with manufacturing and storage of several different common products and goods.
