You won’t find too many houses that don’t feature a refrigerator in the kitchen. It has been a standard kitchen appliance for several years now. A refrigerator can store food at the best temperature, to reduce spoilage and slow down harmful bacteria. The process of refrigeration starts by distributing the warmth from the interior of the appliance to the outside, by using principles of condensation and evaporation.

How Does Refrigeration Work?

1. Once the temperature within the refrigerator is higher than the set point sensors alert the refrigerator compressor to engage, and the next cool down begins. The appliance draws in the cold liquified refrigerant, then condenses and pressurizes the refrigerant, and increases the temperature, turning it into a gas.

2. The compressor unit guides the warm gas towards the condenser coils on the exterior of the appliance, at which point it comes into contact with the lower air temperature in the home and returns to a liquid state.

3. The cool liquified gas then continues its journey to the evaporator component, pushing through the coils within the appliance and freezer compartment.

4. The refrigerant absorbs the hot air from within the appliance, thereby lowering the temperature until it has reached the correct final point.

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

Refrigeration is found in a number of applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing warmth from a single location and distributing it to elsewhere the continuous cycle of refrigeration aids in cooling your house, provides a safe environment for perishable food, and also helps with the manufacturing and storage of a number of different products and goods.
