Problems solved by technology
The problem in the prior art is that the evaporator 1, the air duct 2 and the fan 3' are placed separately, and the volume occupies a large volume; in addition, when the return air passes through the evaporator 1, the wind speed is relatively slow, resulting in low heat exchange efficiency; and, the air duct 2 generally It is necessary to set the air duct back plate 4, so that the manufacturing cost is relatively high

The invention relates to the technical field of refrigerators, and discloses a refrigerator refrigerating system and a refrigerator. The refrigerator refrigerating system comprises an air duct arranged in a refrigerator body, an air return opening and an air outlet, wherein the air return opening and the air outlet are used for communicating the air duct with a refrigerating chamber. The air ductis internally provided with a centrifugal fan and an evaporator. The evaporator is of a closed or non-closed annular structure. The centrifugal fan sucks air flow from the refrigerating chamber through the air return opening, and the air exhausting direction of the centrifugal fan corresponds to the evaporator, so that the air flow exhausted out of the centrifugal fan can be blown into the evaporator, and the air flow cooled through the evaporator enters the refrigerating chamber through the air outlet. According to the refrigerator refrigerating system, by arranging the centrifugal fan and the evaporator in the air duct, the space utilization rate of the refrigerating chamber can be improved; and due to the facts that the centrifugal fan exhaust air towards the inner annular face of the evaporator, and the centrifugal fan sucks the air flow from the refrigerating chamber through the air return opening, so that the air speed when the air passes through the evaporator is high, and the heat exchanging efficiency of the evaporator is high compared with the traditional technology.
Description
technical field [0001] The invention relates to the technical field of refrigerator refrigeration, in particular to a refrigerator refrigeration system and a refrigerator. Background technique [0002] See figure 1 The air-cooling system in the prior art includes an air duct 2 arranged at the rear of the refrigerator liner and a finned evaporator 1 close to the rear of the air duct 2 or the rear of the cabinet of the refrigerator. The return air outlet and the air outlet of the room are connected, and the evaporator 1 uses fins to cool the air flow in the air duct 2. The above-mentioned air duct 2 is also provided with a fan 3', which provides wind pressure when the fan 3' rotates, and the wind passes through the pipeline of the finned evaporator 1 and the fins to exchange heat with the evaporator 1 from the air return port, and finally passes through the air duct 2 to exit. The air outlet supplies air to the compartment. The problem in the prior art is that the evaporato...
