Title:
REFRIGERATION SYSTEM FOR REFRIGERATING AND FREEZING DEVICE, AND REFRIGERATING AND FREEZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/273740
Kind Code:
A1
Abstract:
A refrigeration system for a refrigerating and freezing device, and a refrigerating and freezing device. The refrigeration system comprises a first compressor, a second compressor, a condenser, an evaporator, an intercooler, a first throttling device and a second throttling device, which are connected to form a non-freezing compartment refrigeration flow path, a freezing compartment first refrigeration flow path and an evaporator defrosting flow path. In the non-freezing compartment refrigeration flow path, a refrigerant sequentially flows through the first compressor, the condenser, the first throttling device and a first heat exchange part of the intercooler; in the freezing compartment first refrigeration flow path, the refrigerant sequentially flows through the first compressor, the condenser, a second heat exchange part of the intercooler, the second throttling device, the evaporator and the second compressor, and the first heat exchange part is in thermal connection with the second heat exchange part; and in the evaporator defrosting flow path, the refrigerant sequentially flows through the first compressor, the evaporator, the second throttling device, the first throttling device and the first heat exchange part. The refrigeration system has a high defrosting efficiency and short consumed time and does not affect refrigeration of a non-freezing compartment.
