REFRIGERATION SYSTEM FOR REFRIGERATING AND FREEZING DEVICE, AND REFRIGERATING AND FREEZING DEVICE

WIPO Patent Application WO/2023/273705

A1

A refrigeration system for a refrigerating and freezing device, and a refrigerating and freezing device. The refrigeration system comprises: a refrigeration assembly, which is provided with a compressor and a plurality of evaporating parts, together forming a refrigeration loop, and each evaporating part comprising at least one evaporator; and a plurality of bypass heating parts, which are in one-to-one correspondence with the evaporating parts, wherein each bypass heating part comprises at least one bypass heating pipe, which is thermally connected to at least one evaporator of the corresponding evaporating part on a one-to-one basis, and the bypass heating pipe is used for circulating a refrigerant from the compressor to generate heat, thereby heating the evaporator. A large amount of heat can be generated by the refrigerant from the compressor when the refrigerant flows through the bypass heating pipe, and therefore, the defrosting rate of an evaporator of a multi-system refrigerating and freezing device can be increased by using a defrosting method.
