Abstract

The embodiment of the invention discloses a refrigeration system of a low-temperature storage device, the low-temperature storage device and a control method. The refrigeration system of the low-temperature storage device comprises a compressor, a condenser, an electric control module, an electric control valve and N evaporators, wherein N is an integer greater than 1, an inlet of the electric control module is connected with the condenser, N outlets of the electric control module are connected with a gas suction ports of the compressor through N refrigerant main paths correspondingly, one corresponding evaporator is arranged on each refrigerant main path, a refrigerant branch is arranged between the refrigerant main paths where any two evaporators are located, the refrigerant branches areconnected with the electric control valve, when the any two evaporators are the first evaporator and the second evaporator, the inlet of the electric control valve is connected with the outlet of thefirst evaporator, the first outlet of the electric control valve is connected with the inlet of the second evaporator through the corresponding refrigerant branch, and the second outlet of the electric control valve is connected with the gas suction port of the compressor.

Description

technical field [0001] Embodiments of the present invention relate to the refrigeration field, and in particular to a refrigeration system of a low-temperature storage device, a low-temperature storage device, and a control method. Background technique [0002] At present, multi-chamber refrigerators can use a multi-cycle refrigeration system to independently adjust the temperature of each compartment, but it is impossible to close any one compartment or close any two compartments, making it impossible to meet the diverse requirements of users. [0003] For example: in a freezer that includes three compartments of wine area, refrigeration, and freezing, only the wine compartment or the refrigeration compartment can be closed separately, and the freezer compartment cannot be closed separately, and the freezer compartment cannot be closed. Separate closure of any two compartments. In this way, when the user only needs to use the wine compartment to store ingredients, that is,...
