Tstart setting-tstart actual = -18- (-19.5) =1.5 ℃, the compartment demand factor is determined to be 0.3.
Fig. 4 is a schematic diagram of a refrigeration demand coefficient according to an embodiment of the invention, as shown in fig. 4.Δt2=t Refrigeration setting -T Refrigeration practice (. Degree.C.) when the refrigerating chamber is T Refrigeration setting -T Refrigeration practice The difference in DEG C is 0.6℃, and the corresponding compartment demand coefficient is 1.
Step S300, monitoring whether a refrigerator has a door opening action, if so, determining the door opening time after the refrigerator is closed, and determining the door opening coefficient according to the door opening time;
in the embodiment of the invention, when the method is implemented, whether the refrigerator has a door opening action or not can be monitored by arranging an action sensor in the refrigerator, if so, the door opening time is determined after the refrigerator is closed, and the door opening coefficient is determined according to the door opening time.
In specific implementation, as shown in fig. 5, the corresponding relationship between the door opening time length and the door opening coefficient is preset; for example, the door opening time is set to be 5 minutes, and the corresponding door opening coefficient is set to be 3.5;
setting the door opening time length to be 3 minutes and the corresponding door opening coefficient to be 3;
setting the door opening time length to be 2 minutes, and setting the corresponding door opening coefficient to be 2.5;
and setting the corresponding door opening coefficient to be 2 when the door opening time is 1.2 minutes.
Step 400, calculating the rotating speed of the compressor, the voltage of the fan and the opening angle of the air door according to the changed ring temperature coefficient, the changed compartment demand coefficient and the changed door opening coefficient;
in the embodiment of the invention, the rotating speed of the compressor, the voltage of the fan and the opening angle of the air door are calculated according to the changed ring temperature coefficient, the changed compartment demand coefficient and the changed door opening coefficient.
In the embodiment of the invention, the calculation formula of the rotation speed of the compressor is as follows: compressor speed = reference compressor speed × ring temperature coefficient × refrigeration demand coefficient × door opening coefficient (limit: max 4500rpm (i.e. limit number of revolutions per minute: 4500 revolutions));
reference rotational speed: typically a preset value. In the embodiment of the present invention, the reference rotation speed of the compressor is preferably: 1200rpm.
In the embodiment of the invention, the fan voltage calculation formula is as follows: fan voltage = reference voltage × ring temperature coefficient × refrigeration demand coefficient × door opening coefficient (limit: up to 12V);
reference voltage: typically a preset value. In the embodiment of the invention, the reference voltage of the fan is preferably 7V.
In the embodiment of the invention, the air door opening angle calculation formula is as follows: damper opening angle = reference damper opening angle × ring temperature coefficient × refrigeration demand coefficient × door opening coefficient (limit: maximum opening angle 90 °);
reference damper opening: typically a preset value. In the embodiment of the invention, the reference opening angle of the air door is preferably 30 degrees.
And S500, correspondingly controlling the rotation speed of the refrigerator compressor, the fan voltage and the opening angle of the air door according to the calculated rotation speed of the compressor, the fan voltage and the opening angle of the air door.
In the embodiment of the invention, the rotation speed of the refrigerator compressor, the fan voltage and the opening angle of the air door are correspondingly controlled according to the calculated rotation speed of the compressor, the fan voltage and the opening angle of the air door. Specifically, in the embodiment of the present invention, preferably, the preset maximum rotation speed is 4500rpm (rotation times per minute): the preset highest voltage is 12V; the preset maximum angle is 90 degrees.
When the calculated rotation speed of the compressor exceeds a preset maximum rotation speed (for example, exceeds 4500 rpm), the rotation speed of the compressor is adjusted according to the preset maximum rotation speed, namely, the rotation speed of the compressor is adjusted to 4500rpm, namely, the rotation number of the compressor per minute is adjusted to 4500 rpm.
When the calculated fan voltage exceeds a preset maximum voltage (for example, 12V), the fan voltage is adjusted according to the preset maximum voltage, for example, the fan voltage is adjusted to be 12V.
As shown in fig. 6 and 7, when the calculated damper opening angle exceeds a preset maximum angle (e.g., 90 °), the damper opening angle is adjusted according to the preset maximum angle, e.g., the damper opening angle is adjusted to 90 °.
In the embodiment of the invention, whether the ring temperature coefficient and the chamber demand coefficient change or not can be periodically or irregularly monitored, namely, the environment temperature and the actual measurement temperature of the chamber can be periodically or irregularly monitored. The change of the door opening coefficient depends on whether the door is opened or closed, so that the door opening and closing action of the refrigerator can be monitored.
In specific application, as shown in fig. 8, the ambient temperature is collected first, the room temperature, such as the actual freezing temperature, the actual refrigerating temperature, the actual wetting temperature, etc., is collected, whether the refrigerator is opened or not is detected, and if yes, the opening time of the refrigerator is collected. And obtaining a ring temperature coefficient, a compartment demand coefficient and a door opening coefficient according to internal calculation by a MUC processing module of the refrigerator. And then, correspondingly controlling the rotation speed of the refrigerator compressor, the fan voltage and the opening angle of the air door according to the calculated rotation speed of the compressor, the fan voltage and the opening angle of the air door.
The freezing compartment will be exemplified below. Fig. 3 is a schematic diagram of a refrigeration demand coefficient according to an embodiment of the present invention, as shown in fig. 3, a refrigeration demand coefficient Δt1=tcrjset-tcrjmeasured, when Δt1>1 (for example, the set temperature is-18 ℃, the measured temperature is-19.5 ℃), the refrigeration measured temperature is lower than the set temperature, the larger the difference value is, the larger the deviation between the two is, which indicates that the refrigeration capacity of the refrigeration chamber is sufficient, and the corresponding refrigeration demand coefficient is small. On the contrary, when Δt1 is less than 1 (for example, the set temperature is-18 ℃, the measured temperature is-16.5 ℃), the measured freezing temperature is higher than the set temperature, the smaller the difference value is, which indicates that the freezing chamber is in the cooling process, and the corresponding freezing demand coefficient is large. The refrigeration requirement coefficient is the same.
Meanwhile, according to the actual test of the ring temperature (environmental temperature), the corresponding ring temperature coefficient can be determined, as shown in the ring temperature coefficient schematic diagram shown in fig. 2, when the ring temperature is higher, the load becomes larger, the ring temperature coefficient is larger, and the rotation speed of the compressor and the voltage of the fan need to be increased.
On the other hand, according to the door opening time of the refrigerator, the door opening coefficient is set, as shown in the door opening coefficient schematic diagram in fig. 5, when the door opening time of the refrigerator is longer, the opening angle of the air door is increased through the door opening coefficient adjustment of the refrigerator, so that the cooling capacity is supplemented.
When the invention is embodied, whether each coefficient changes or not can be set and adjusted at any time if the detection is carried out once every t1 time.
