Embodiment 1

[0017] like figure 1 As shown, the refrigerator refrigeration system of the present invention includes components such as a compressor 1, a condenser 2, a solenoid valve 3, a capillary tube and an evaporator, and the above components form a closed loop of circulation through pipelines. Wherein, the capillary includes a refrigeration capillary 41, a variable temperature capillary and a freezing capillary 43; The refrigerated variable temperature capillary 62, the evaporator includes a refrigerated evaporator 51, a variable temperature evaporator and a freezing evaporator 53, and the variable temperature evaporator includes two parts, namely a variable temperature evaporator 521 and a variable temperature evaporator 2 522. In the freezing variable temperature branch 421, the freezing variable temperature capillary 61 is connected in series with variable temperature evaporator 1 521 and variable temperature evaporator 2 522;

[0018] During work, cooling is carried out by select...

Embodiment 1

[0022] Compared with the first embodiment, the difference of this embodiment is that the freezing variable temperature capillary 61 is connected in series with the variable temperature evaporator 522, and the refrigeration variable temperature capillary 62 is connected in series with the variable temperature evaporator 2 521.

[0023] During work, for example, when the temperature-changing greenhouse is set below 0°C, the freezing variable-temperature capillary 61 is opened to realize cooling of the variable-temperature evaporator 2 522 to realize the freezing effect; when the temperature is set above 0°C, only the refrigerated variable-temperature capillary 62 is opened to realize Refrigerate the temperature-variable evaporator-521 to realize the refrigeration effect.

[0024] As an improvement, the variable temperature evaporator 522 is arranged on both sides of the variable temperature chamber, and the variable temperature evaporator 521 is arranged on the top of the variabl...

Abstract

The invention relates to a refrigeration system, in particular to a refrigeration system for a three-door multi-temperature-zone refrigerator. The invention also relates to a refrigerator, in particular to a three-door multi-temperature-zone refrigerator with the refrigeration system. The variation range of temperature of a variable temperature zone is increased, and the defrosting problem and large temperature difference problem are effectively solved. The three-door multi-temperature-zone refrigerator is provided, and the refrigeration effect of the refrigerator is optimized. The three-door multi-temperature-zone refrigerator comprises a fresh-food storage compartment, a variable temperature compartment, a freezer and a refrigeration system, wherein the refrigeration system comprises a refrigeration loop, a variable temperature refrigeration loop and a freezing refrigeration loop, and the three refrigeration loops are respectively used for refrigeration of the fresh-food storage compartment, the variable temperature compartment and the freezer of the refrigerator; and the variable temperature refrigeration loop is at least provided with two branches, one is a refrigeration variable temperature branch, and the other is a freezing variable temperature branch; and the variable temperature branch loops comprise evaporators. The refrigerator provided by the invention has the beneficial effects that the variable temperature compartment refrigeration loop is provided with at least two variable temperature branches, each branch can be controlled for refrigeration according to the actual needs, the defrosting problem and the large temperature difference problem can be effectively solved, and the refrigeration effect of the refrigerator is optimized.

Description

[0001] technical field [0002] The present invention relates to a refrigeration system, specifically a refrigeration system for a three-door multi-temperature zone refrigerator; and also relates to a refrigerator, specifically a three-door multi-temperature zone refrigerator equipped with the refrigeration system. Background technique [0003] A refrigerator is a device used for cooling and for preserving food. The quality of a refrigerator depends mainly on the quality of its refrigeration system. With the continuous development of people's quality of life and technology, refrigerators have now developed from simple freezing and refrigeration functions to multi-temperature zone structures. For example: three-door multi-temperature zone refrigerator. [0004] At present, the refrigeration system of the three-door multi-temperature zone refrigerator is mainly a three-way capillary refrigeration circuit, that is, a double solenoid valve is used to control the opening and cl...
