How Does Refrigeration Work?

1. Once the temperature within the refrigerator goes above the set point sensors notify the refrigerator compressor to engage, and the cooling cycle starts. The appliance collects the cold liquid refrigerant, then condenses and pressurizes the refrigerant, and increases the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit guides the hot gas towards the condenser coils located on the exterior of the appliance, where it comes into contact with warmer temperature in the kitchen and reverts back to a liquified state.

3. The cool refrigerant then continues on its trip to the refrigerator evaporator, making its way through the many coils within the refrigerator and freezer section.

4. The liquid then absorbs the warm air from inside the refrigerator, lowering the temperature back to the desired final point.

5. The refrigerant then will evaporate, and will turn back to a gas, and returns to the refrigerator compressor unit so it can then continue the cycle.

Refrigeration technology is often found in a number of applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By removing heat from a single place and distributing it to elsewhere the continuous cycle of refrigeration helps cooling your home, provides a safe environment for perishable food, and helps with manufacturing and storage of a lot of different products and goods.
