Once the evaporator isn’t working, it is time to enlist a professional. Don’t wait too long.

How Does Refrigeration Work?

1. The moment the temperature within the refrigerator is above the set point sensors alert the compressor to begin, and the cool down starts. The appliance draws in the cold liquified refrigerant, pressurizes and condenses it, and increases the temperature, in order to turn it into a gas.

2. The refrigerator compressor pushes the heated gas in the direction of the refrigerator condenser coils located on the exterior of the unit, where it comes into contact with the lower air temperature in the room and reverts to a liquid state.

3. The cooled liquid continues its trip to the evaporator, traveling through the many coils in the interior of the appliance and freezer.

4. The refrigerant then absorbs the warm air from inside the appliance, returning the temperature back to the optimal final point.

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

Refrigeration technology is often found in many applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting heat from a single area and relocating it to somewhere else the continuous cycle of refrigeration helps cooling a house, provides a optimal space for food that is perishable, and helps with manufacturing and storage of several different everyday products and materials.
