Refrigerating system for refrigerating and freezing device and refrigerating and freezing device with refrigerating system

Abstract

The invention provides a refrigerating system for a refrigerating and freezing device and the refrigerating and freezing device with the refrigerating system. The refrigerating system comprises a refrigerating assembly and an attachment assembly, wherein the refrigerating assembly is provided with a compressor and a plurality of evaporators which form a refrigerating loop; the attachment assembly is connected to the refrigerating loop and provided with a plurality of evaporation switching valves arranged in one-to-one correspondence with the evaporators and a plurality of evaporation bypass pipelines arranged in one-to-one correspondence with the evaporators; each evaporation switching valve is provided with a valve port used for communicating with the corresponding evaporator and a valve port used for communicating with the corresponding evaporation bypass pipeline; and each evaporation switching valve is configured to adjust a refrigerant flowing path flowing through the evaporation switching valve by adjusting the opening and closing state of each valve port of the evaporation switching valve, so that the working state of the corresponding evaporator is adjusted. The structure of the refrigerating system is improved, the flowing paths of refrigerants are diversified through the attachment assembly, and therefore the working state of each evaporator can be independently adjusted conveniently.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigeration system for a refrigeration and freezing device and a refrigeration and freezing device having the same. Background technique [0002] Refrigeration and freezing devices, such as refrigerators, freezers, storage cabinets, etc., use the refrigeration system to provide cold energy to the storage space, thereby creating a low-temperature fresh-keeping atmosphere for the storage space. With the continuous improvement of people's living standards, people can come into contact with a variety of items in daily life, and different items often correspond to different preservation needs. Existing refrigerating and freezing devices generally have multiple storage spaces, such as multi-system refrigerators, and each storage space needs to be equipped with an evaporator, so as to adjust the fresh-keeping atmosphere of each storage space. [0003] The inventor realized that the multip...

AI Technical Summary

Problems solved by technology

[0003] The inventor realized that the multiple evaporators of the existing refrigerating and freezing devices are generally connected to the refrigeration circuit in series or in parallel, the refrigerant can only flow in the refrigeration circuit, the flow path of the refrigerant is relatively single, and it is difficult to independently adjust each evaporator. The working state of the device, the flexibility is poor
