In some embodiments, the first fitting relation may include a fitting relation between a length of the retractable baffle and an air supply distance.

In practice, as shown in fig. 2, 3, 4 and 5, when the length of the retractable baffle ring is L and the air blowing distance is S, the fitting relation between the length L of the retractable baffle ring and the air blowing distance S is S ═ f (L). Air supply distance S influences the direct blowing effect of cold air to goods in the freezer, and goods surface moisture runs off easily under the convection action, then influences the goods storage cycle easily. Considering that the air pressure on the surface of the goods is large and the water loss is large; the air pressure is little, and the moisture runs off for a short time to and, the influence that air supply way air resistance caused, effective control S value can be under the condition that combines the pressure loss of air pressure, and the control improves goods storage cycle to the direct-blow condition on goods surface.

Specifically, the specific fitting relationship of the first fitting relationship equation S ═ f (l) needs to be set according to the actual conditions of the refrigerator, and is not limited here.

The left and right air supply angles theta influence the uniformity of air supply of the air cooler to the refrigeration house, the theta value is effectively controlled, the control on a refrigeration house temperature field can be realized, and the maximum temperature difference value of the refrigeration house is controlled.

Specifically, the specific fitting relationship of the second fitting relationship equation θ ═ f (d) needs to be set according to the actual conditions of the refrigerator, and is not limited here.

In some embodiments, the third fitting relation may include a fitting relation between an up-down air supply angle of the retractable baffle and a height of the cargo to the air cooler.

In implementation, as shown in fig. 2, 4 and 5, the vertical air supply angle of the retractable baffle is β, the height of the cargo to the air cooler is H, and the fitting relation between the vertical air supply angle β of the retractable baffle and the height H of the cargo to the air cooler is β ═ f (d). The upper and lower air supply angles beta affect the uniformity of air supply of the air cooler to the refrigeration house, the beta value is effectively controlled, the control on a refrigeration house temperature field can be realized, and the maximum temperature difference value of the refrigeration house is controlled.

Specifically, the specific fitting relationship of the third fitting relationship equation β ═ f (d) needs to be set according to the actual conditions of the refrigerator, and is not limited here.

When the air cooler operates, the monitoring and recognizing device monitors the storage condition of the refrigeration house in real time, and recognizes the air supply distance S, the maximum width D of the goods and the height H of the goods to the air cooler. After the air supply distance S, the maximum width D of the goods and the height H of the goods to the air cooler are obtained, the length of the telescopic guide ring can be calculated according to the first fitting relational expression, the second fitting relational expression and the third fitting relational expression respectively, the air supply angle is controlled, the air supply angle is adjusted up and down, then the telescopic guide ring and the rotating module are controlled according to the calculated length of the telescopic guide ring, the air supply angle is controlled, the air supply mode (the air supply angle and the air supply range) is adjusted in a self-adaptive mode, and a more efficient freezing preservation mode is provided for users.

In order to further improve the freezing and fresh-keeping capacity of the refrigeration house, in some embodiments, when the storage condition of goods in the refrigeration house is monitored, the monitoring information may further include temperature information. So, after acquiring the monitoring information that monitoring recognition device sent, can also calculate according to temperature information and settlement temperature and obtain the target difference in temperature, then based on the fourth fitting relational expression that sets up in advance, confirm the air supply volume through the target difference in temperature, can control the fan air supply of air-cooler according to the air supply volume of confirming at last.

The target temperature difference is the difference value information between the temperature information of the refrigeration house monitored by the monitoring and identifying device and the set temperature of the refrigeration house set by a user. The fourth fitting relational expression may be a fitting relational expression of the air volume of the air cooler and the target temperature difference.

During implementation, the set temperature can be T, and the refrigeration house monitored by the monitoring and identifying deviceThe real-time temperature information is T^-1If the target temperature difference Δ T is equal to T^-1T, the air supply amount Q and the target temperature difference Δ T have a fitting relationship Q ═ F (Δ T), and thus, the temperature information T is determined^-1And after the temperature T is set, the target temperature difference delta T can be calculated, and then the air delivery quantity Q is calculated.

Specifically, the specific fitting relationship of the fourth fitting relationship Q ═ F (Δ T) needs to be set according to the actual condition of the refrigerator, and is not limited here.

In addition, when the air supply of the fan is controlled according to the air supply quantity, the air supply of the fan of the air cooler can be controlled steplessly according to the air supply quantity, so that the stable change of the temperature is ensured, and the freezing and fresh-keeping effects are ensured.
