Title:
REFRIGERATING SYSTEM FOR REFRIGERATING AND FREEZING DEVICE AND REFRIGERATING AND FREEZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/273709
Kind Code:
A1
Abstract:
A refrigerating system for a refrigerating and freezing device and the refrigerating and freezing device. The refrigerating system comprises: a refrigerating assembly, provided with a compressor and an evaporator for forming a refrigerating loop; and a bypass defrosting pipe, connected to the refrigerating loop and configured to circulate a refrigerant from the compressor to generate heat. The bypass defrosting pipe is thermally connected to the evaporator to heat the evaporator. By improving the structure of the refrigerating system, a novel defrosting mode is provided, and when the refrigerant from the compressor is introduced into the bypass defrosting pipe and heat is generated, the evaporator can be heated to enable the evaporator to defrost. Due to the fact that a large amount of heat can be generated when the refrigerant from the compressor flows through the bypass defrosting pipe, the defrosting speed of the evaporator can be increased by adopting the defrosting mode, and rapid, efficient and thorough defrosting of the evaporator is achieved.
