The invention provides a refrigerator with a volute centrifugal fan. The refrigerator comprises a refrigerator body, an evaporator, the centrifugal fan and an air supply air duct, wherein a cooling chamber located in the lower part of the refrigerator body and at least one storage chamber located above the cooling chamber are defined in the refrigerator body, the evaporator is arranged in the cooling chamber, and is configured to be used for cooling air flow entering the cooling chamber so as to form the cooling air flow, the centrifugal fan comprises a volute and an impeller arranged in the volute, the air supply air duct is detachably connected with the volute and communicates with a volute air outlet, and the air supply air duct is arranged to convey the cooling air flow into at least one storage chamber. According to the refrigerator, the cooling chamber is located in the lower part of the refrigerator body, so that the cooling chamber occupies the lower space in the refrigerator body, the storage chamber is located above the cooling chamber, a press chamber can be defined behind the cooling chamber, the storage chamber does not need to offer a place for the press chamber any longer, and the storage volume of the storage chamber is ensured. In addition, the air supply air duct and the centrifugal fan are designed in a split mode, so that modularization is realized, disassembly, assembly and transportation are facilitated, and the yield is improved.
