Abstract
Disclosed herein are a refrigerator capable of preventing frost from forming on an evaporator by mounting a dehumidifying unit and a recycling unit on both sides of the evaporator, respectively, and a controlling method thereof. Cold air in a storage chamber is dehumidified as the air passes through the dehumidifying unit and is sent to the evaporator. The cold air thermally exchanged in the evaporator is humidified as the air passes through the recycling unit and is sent to the storage chamber.
