Refrigerating system and refrigerating and freezing device with same

The utility model relates to the technical field of refrigerating and freezing devices, in particular to a refrigerating system and a refrigerating and freezing device with the same. The refrigerating system comprises a refrigerating assembly, wherein the refrigerating assembly is provided with a compressor, a condenser assembly and two evaporators which are used for forming a refrigerating loop; and the throttling assembly is connected to the refrigerating circuit and used for switching the flow direction of a refrigerant in the refrigerating circuit, so that the two evaporators are arranged between the air inlet of the compressor and the outlet end of the condenser assembly in a parallel connection or series connection mode. According to the refrigerator, the frosting cooling capacity of the evaporator needing to be defrosted is recycled, the recycled cooling capacity is conveyed to the chamber needing to be refrigerated while the chamber needing to be defrosted is defrosted, the heat efficiency is improved
