In some optional embodiments, the refrigerator 100 may achieve a higher technical effect by further optimizing and configuring the above steps, and the following describes in detail the air supply control method of the refrigerator of this embodiment in combination with a description of an optional execution flow of this embodiment, where this embodiment is merely an illustration of the execution flow, and in a specific implementation, an execution sequence and an operation condition of some steps may be modified according to specific implementation requirements. Fig. 5 is a detailed flowchart of a blowing control method of a refrigerator according to an embodiment of the present invention. The air supply control method of the refrigerator comprises the following steps:
step S502, obtaining the number of turns of the motor, and determining the actual position of the rack 150 according to the number of turns;
step S504, calculating the upper volume and the lower volume of the rack 150 according to the actual position;
step S506, calculating the product of the upper volume and a first preset coefficient to obtain a first air supply quantity, and calculating the product of the lower volume and a second preset coefficient to obtain a second air supply quantity;
step S508, acquiring a wind speed of an air supply fan of the refrigerator 100;
step S510, calculating a quotient of the first air supply quantity and the air speed to obtain a first air outlet area, and calculating a quotient of the second air supply quantity and the air speed to obtain a second air outlet area;
step S512, inquiring an air supply information table to obtain a first switch angle corresponding to the first air outlet area and a second switch angle corresponding to the second air outlet area in a matching manner;
in step S514, the first damper 141 is controlled to a first opening/closing angle, and the second damper 142 is controlled to a second opening/closing angle.
In the above steps, the specific step of calculating the upper volume and the lower volume of the rack 150 according to the actual position in step S504 may include: determining a first height of the rack 150 from the top of the storage space 111 and a second height from the bottom of the storage space 111 according to the actual positions; acquiring the length and width of the storage space 111 obtained in advance; and multiplying the length and the width by the first height to obtain an upper volume, and multiplying the length and the width by the second height to obtain a lower volume.
In step S506, a product of the upper Fang Rongji and the first preset coefficient is calculated to obtain a first air supply amount, and a product of the lower volume and the second preset coefficient is calculated to obtain a second air supply amount. In practice, the specific calculation procedure may be as follows: since the heat load is proportional to the volume, the heat load above the rack 150 can be obtained according to the upper volume and the heat load below the rack 150 can be obtained according to the lower volume; in the case where the temperature difference between the evaporator and the storage space 111 is constant, the air blowing amount is also proportional to the heat load, and therefore, the first air blowing amount can be obtained according to the heat load above the rack 150 and the second air blowing amount can be obtained according to the heat load below the rack 150. By integrating the above calculation processes, it can be determined that the air supply amount is proportional to the volume, and therefore, the first air supply amount can be obtained by calculating the product of the upper volume and the first preset coefficient, and the second air supply amount can be obtained by calculating the product of the lower volume and the second preset coefficient. The first preset coefficient and the second preset coefficient may be the same or different, and may be set in advance according to actual conditions and experimental results.
In the air supply information table in step S512, the switch angles corresponding to different air outlet areas are stored in advance, so that a first switch angle corresponding to the first air outlet area and a second switch angle corresponding to the second air outlet area can be obtained by querying the table through matching. Further, the first damper 141 is controlled to a first opening/closing angle, and the second damper 142 is controlled to a second opening/closing angle.
It should be noted that, after the step of controlling the first damper 141 to the first opening and closing angle and the step of controlling the second damper 142 to the second opening and closing angle in step S514, the method may further include: acquiring the actual temperature of the storage space 111; judging whether the actual temperature reaches the starting temperature of the storage space 111; and if so, controlling a refrigeration system of the refrigerator 100 to be started to supply air to the storage space 111. That is, after the opening and closing angles of the first damper 141 and the second damper 142 are determined in advance according to the actual positions of the racks 150, the air can be supplied to the upper side of the racks 150 according to the first opening and closing angle and to the lower side of the racks 150 according to the second opening and closing angle when the refrigeration system starts to perform the refrigeration. It should be noted that, after the position of the rack 150 is changed each time, the actual position thereof may be determined, and then the opening and closing angles of the first damper 141 and the second damper 142 are adjusted, so that the air supply condition after the start of refrigeration conforms to the volume separation condition of the storage space 111, and the uniform temperature distribution in the storage space 111 is effectively ensured. In addition, when the actual temperature of the storage space 111 reaches the shutdown temperature, the refrigeration system may be controlled to be turned off, and no air is supplied to the storage space 111.
