A freezing and refrigerating device and defrosting control method thereof. The freezing and refrigerating device (1) comprises a container body (100) and a door body (200). The container body (100) is provided with at least one storage chamber an air supply path for supplying a cooling air flow to the storage chamber an air return path for the air flow flowing from the storage chamber to flow therethrough a cooling chamber (40) communicating with the air supply path and the air return path and accommodating an evaporator (41) a fan (42) and a defrosting heater (43) and an air exhaust path (50) communicating the cooling chamber (40) and a surrounding space. The air supply path and the air exhaust path (50) are respectively provided with an air supply door and an air exhaust door (51) therein to selectively open and/or close the air supply path and the air exhaust path (50). The defrosting control method comprises the steps of receiving a defrosting signal activating the defrosting heater (43) located on the evaporator (41) closing the air supply door and opening the air exhaust door (51) to exhaust hot air generated during defrosting to the surrounding space.
