Air-cooled refrigerator refrigeration module and control method thereof

Abstract

The invention relates to an air-cooled refrigerator refrigeration module and a control method thereof, and relates to the technical field of refrigeration equipment. An evaporator, a compressor, a condenser, a filter and a flow switch valve are sequentially connected, and the evaporator, the compressor, the condenser, the filter, the flow switch valve, a first capillary and a second capillary form a refrigeration circulation loop; the first capillary and the second capillary are arranged in parallel and connected between the evaporator and the flow switch valve; the flow switch valve is used for controlling a flow direction of a refrigerant, and makes the refrigerant flow through the first capillary or the second capillary, and a first fan and a second fan have individual air duct structures and share one evaporator. According to the air-cooled refrigerator refrigeration module and the control method of the air-cooled refrigerator refrigeration module, the two fans are arranged in the two individual air duct structures, and share one evaporator so as to form a high-temperature air duct structure and a low-temperature air duct structure, and air volume circulation is conducted between the high-temperature air duct structure and a high-temperature compartment, the low-temperature air duct structure and a low-temperature compartment respectively; on the basis of a single evaporator structure, low cost can be maintained, and meanwhile the cooling efficiency can be improved; mutual matching of the refrigeration circulation loop and the air duct structures can be achieved through the flow switch valve so as to adapt to needs of multiple working conditions, and the energy consumption of a refrigerator is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration module for an air-cooled refrigerator and a control method thereof. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common electrical appliance used for low-temperature preservation of food or other items in daily life. It is widely used in life and industry. Refrigerated and frozen dual-temperature zone air-cooled refrigerators are one of the most common types of refrigerators. At present, the refrigeration structure of refrigerated and frozen dual-temperature zone air-cooled refrigerators has two forms: single evaporator and single fan and double evaporator and double fan. The cooling structure of single evaporator and single fan The main body of the air duct and the evaporator are installed in the low-temperature freezer, and the cooling of the refrigerator is controlled b...
