Abstract

The application discloses a refrigeration device and a control method thereof, wherein the control method comprises the steps of controlling a refrigeration air supply system to start to supply air into a compartment; controlling the oxygen regulating module to start to convey oxygen regulating airflow to the compartment, and controlling the air supply amount of the oxygen regulating module and the air supply amount of the refrigerating air supply system to be gradually reduced in a stepped mode. According to the application, the oxygen regulating air flow is supplied to the interior of the compartment by controlling the oxygen regulating module, so that the oxygen concentration in the compartment can be regulated to improve the fresh-keeping effect in the compartment, and further, the influence of the air supply of the refrigeration air supply system on the oxygen regulating air flow conveyed by the oxygen regulating module can be reduced by controlling the air supply amount of the oxygen regulating module and the air supply amount of the refrigeration air supply system to be gradually reduced in a stepped manner, thereby avoiding the deviation of the oxygen concentration in the compartment from the preset oxygen-enriched environment or the preset oxygen-deficient environment, and further improving the fresh-keeping effect of the compartment.
