Abstract

The invention relates to an air-cooled refrigerator temperature control method and system. The method comprises the steps that a target temperature value of a refrigerator refrigerating chamber is set, and a compressor is controlled to start; the real-time temperature of the refrigerating chamber and the real-time temperature of a freezing chamber are acquired; the acquired real-time temperature of the refrigerating chamber is compared with the target temperature value of the refrigerating chamber; when the real-time temperature of the refrigerating chamber is equal to the target temperature value of the refrigerating chamber, the acquired real-time temperature of the freezing chamber is compared with a default temperature of the freezing chamber; when the real-time temperature of the freezing chamber is equal to the default temperature of the freezing chamber, the compressor is controlled to stop working. According to the air-cooled refrigerator temperature control method and system, only the temperature of the refrigerating chamber needs to be adjusted, the temperature of the freezing chamber is controlled full-automatically, the design requirements for food storage in the freezing chamber are met, the system can automatically run a program without manual adjustment and control, operation is easy, cost is low, the requirement for the use temperature of a refrigerating system and the requirement for the use temperature of a freezing system can be met separately, the phenomenon that only the refrigerating temperature of a mechanical refrigerator can be controlled, and the temperature of a freezing chamber cannot be controlled is avoided, and the requirement for energy conservation is met.

Description

technical field [0001] The invention relates to the technical field of refrigerator control, in particular to an air-cooled refrigerator temperature control method, a control system and an air-cooled refrigerator. Background technique [0002] The control method of air-cooled refrigerators is mostly that the compressor performs operation control according to the temperature set for refrigeration and freezing. The refrigeration temperature is generally set at 1 to 8°C, and the freezing temperature is generally set at -16 to -24°C. The disadvantage is that refrigeration and freezing are separated. Temperature adjustment, its operation is complicated; compared with ordinary mechanical refrigerators, the cost is higher, and the freezer and refrigerator are connected through the air duct, which is easy to cause the air duct to freeze and cause refrigeration failure. Existing air-cooled refrigerators control the temperature of the refrigerating and freezing chambers separately, th...
