Refrigerator and control method thereof

Abstract

The invention provides a refrigerator and a control method thereof. The refrigerator comprises a compressor, a condenser, a first liquid storage tank, a shunting device, a first throttling device, a cold storage evaporator, a second throttling device, a refrigeration evaporator and a second liquid storage tank, wherein an inlet of the condenser is communicated with an exhaust port of the compressor, and an inlet of the first liquid storage tank is communicated with an outlet of the condenser; an inlet of the shunting device is communicated with an outlet of the first liquid storage tank, an outlet of the shunting device is communicated with the first throttling device and the second throttling device respectively, the first throttling device is communicated with the cold storage evaporator, the second throttling device is communicated with the refrigeration evaporator, and the second liquid storage tank is communicated with the refrigeration evaporator and the cold storage evaporator respectively. According to the refrigerator, the first liquid storage tank is added between the condenser and the shunting device, so that sufficient refrigerants are provided when cold storage and refrigeration are operated simultaneously, the condition of insufficient liquid supply during simultaneous operation of cold storage and refrigeration is avoided, the cold storage and refrigeration effects of a product are improved, and the use demand of a client is met.

Description

Technical field [0001] The invention relates to the technical field of refrigeration equipment, and in particular to a refrigerator and a control method thereof. Background technique [0002] At present, the existing double evaporator refrigeration system of refrigerators includes: compressor, condenser, filter drier, three-way valve, refrigerating capillary tube, refrigerating capillary tube, refrigerating evaporator, refrigerating evaporator and liquid storage tank. When running alone or at the same time of refrigeration and freezing, the required refrigerant flow is different, which will easily lead to insufficient refrigerant supply due to the simultaneous operation of refrigeration and freezing, which will affect the refrigeration and freezing effects of the refrigerator and cannot meet the needs of customers. Summary of the invention [0003] In order to solve at least one of the above-mentioned technical problems, an object of the present invention is to provide a refrigera...
