What Is a Refrigerator Evaporator; Why Is It Important?

Jan 12, 2021 The refrigerator evaporator is one part of the refrigeration cycle that makes the inside of your refrigerator cold. After the refrigerant gas has gone through the condenser coils located at the back of the refrigerator, it starts to cool down and turn into a liquid. It’s at this liquid stage that the refrigerant reaches the expansion valve.
