Abstract

The invention discloses a single-system air-cooled refrigerator. The single-system air-cooled refrigerator comprises at least one refrigeration compartment, an evaporator, an air supply duct, an air return duct, at least one heat exchange piece set and an air return heat exchange piece set, wherein the heat exchange piece set comprises two independently-arranged air supply heat exchange pieces and an air supply heat pipe connected with the two air supply heat exchange pieces, and the air supply heat pipe is used for achieving heat transfer between the two air supply heat exchange pieces; one of the air supply heat exchange piece is arranged in the air supply duct; the other air supply heat exchange piece is arranged in the refrigeration compartment or close to the evaporator; the air return heat exchange piece set comprises two independently-arranged air return heat exchange pieces and an air return heat pipe connected with the two air return heat exchange pieces, and the air return heat pipe is used for achieving heat transfer between the two air return heat exchange pieces; one of the air return heat exchange piece is arranged in the air return duct; and the other air return heat exchange piece is arranged in the refrigeration compartment or close to the evaporator. The single-system air-cooled refrigerator is low in cost and ensures that the refrigeration compartment has the better refrigerating effect.

Description

technical field

[0001] The invention relates to the field of household appliances, in particular to a single-system air-cooled refrigerator. Background technique

[0002] In the prior art, refrigerators generally refer to single-door, double-door, double-temperature, three-door, three-temperature, and cabinet-type multi-door refrigerators, which generally have independent freezers and refrigerators for separate storage according to different storage temperatures. The refrigeration principle of this refrigerator-freezer is divided into direct cooling and air cooling. Direct-cooling refrigeration systems often use solenoid valves to control the flow of refrigerant, and supply refrigerant to the evaporators of each refrigerating (freezing) room to cool each space to the required temperature. Air-cooled refrigerators and freezers need to set up corresponding air ducts to supply air to each space.

[0003] Compared with direct-cooling refrigerators, air-cooled refrigerators hav...
