As shown in fig. 1, a control method of a refrigeration apparatus according to an embodiment of a first aspect of the present invention includes:
According to the control method of the refrigeration equipment in the embodiment of the first aspect of the invention, the actual defrosting temperature is obtained only through the defrosting sensor 504, and then the actual opening degree of the electronic expansion valve 502 is matched and adjusted according to the pre-stored preset opening degree of the electronic expansion valve 502, so that a larger refrigerant flow can be obtained, that is, in the process, the flow of the refrigerant can be adjusted in real time along with the change of the actual working condition of the refrigeration equipment without additionally introducing other environment variables or arranging other sensors and other components, so that the refrigeration equipment is ensured to be in a better rapid refrigeration state. By using the electronic expansion valve 502 in the refrigeration equipment, the flow of the refrigerant in the refrigeration equipment can be adjusted within a wider amplitude range, and the refrigeration equipment has the advantages of sensitive response, high adjustment precision and the like. The refrigeration equipment can be ensured to be in the optimal rapid refrigeration stage, the energy consumption of the refrigeration equipment can be reduced, the control logic is simple, and the universality is high.
Specifically, taking the refrigeration apparatus as an example of a refrigerator, in step 100, the actual defrosting temperature of the evaporator 500 may be directly acquired by a defrosting sensor 504 of the refrigerator. In other words, in the control method of the refrigeration apparatus provided in the embodiment of the present invention, the actual defrosting temperature of the evaporator 500 can be collected by the defrosting sensor 504 of the refrigerator without additionally introducing other sensors and other devices.
In step 200, the actual opening degree of the electronic expansion valve 502 is adjusted according to the actual defrosting temperature collected in step 100, and in this step, the pre-stored preset opening degree of the electronic expansion valve 502 can be directly called by looking up a table to correspondingly adjust the actual opening degree of the electronic expansion valve 502, so that the refrigerator can be in an optimal refrigeration cycle, and the flow rate of the refrigerant in the refrigerator can be ensured to be matched with the current operation condition of the refrigerator.
According to an embodiment of the present invention, the step of adjusting the actual opening degree of the electronic expansion valve 502 according to the actual defrosting temperature comprises:
step 210, calibrating a preset opening degree of the electronic expansion valve 502 based on a preset defrosting temperature;
and step 220, matching the actual defrosting temperature with the preset defrosting temperature to determine the actual opening degree based on the corresponding preset opening degree.
In step 210, the preset opening degree of the electronic expansion valve 502 is calibrated in advance by presetting the defrosting temperature. In other words, in step 210, the preset opening degree of the electronic expansion valve 502 needs to be calibrated in advance, so that in step 220, the control system 506 of the refrigerator can directly call the preset opening degree of the electronic expansion valve 502 as the actual opening degree of the electronic expansion valve 502 based on the matching result of the actual defrosting temperature of the defrosting sensor 504 and the preset defrosting temperature, thereby realizing the adjustment of the refrigerant flow.
In the embodiment of the present invention, the preset opening degree of the electronic expansion valve 502 may be calibrated in at least the following two ways:
the calibration method is as follows:
in this calibration manner, the step of calibrating the preset opening degree of the electronic expansion valve 502 based on the preset defrosting temperature includes:
step 211, adjusting the preset opening degree of the electronic expansion valve 502 to the maximum opening degree and gradually reducing the opening degree;
step 212, acquiring the actual defrosting temperature;
step 213, determining that the operation condition of the refrigeration equipment meets the preset condition, adjusting the preset opening of the electronic expansion valve 502 to the adjusted opening, and calibrating the adjusted opening of the electronic expansion valve 502 to the preset opening of the electronic expansion valve 502.
In step 211, first, the preset opening degree of the electronic expansion valve 502 is adjusted to the maximum opening degree, and the preset opening degree of the electronic expansion valve 502 is gradually decreased with the operation time of the refrigerator;
in step 212, acquiring an actual defrosting temperature collected by the defrosting sensor 504 based on preset opening degrees of different electronic expansion valves 502;
in step 213, when the operation condition of the refrigerator meets the preset condition, the preset opening of the electronic expansion valve 502 is readjusted to the adjusted opening, and after the adjustment is completed, the adjusted opening of the electronic expansion valve 502 is calibrated to the preset opening of the electronic expansion valve 502 under the current condition.
It should be noted that, in step 213, the operation condition of the refrigerator meeting the preset condition specifically means that the refrigerator is operated to a stable state, and meanwhile, the temperature of the refrigeration compartment inside the refrigerator is not reduced any more, which is the preset condition of the refrigerator under the current operation condition.
According to an embodiment of the present invention, in step 213, determining that the operation condition of the refrigeration equipment satisfies the preset condition, adjusting the current preset opening degree of the electronic expansion valve 502 to the adjusted opening degree, and calibrating the adjusted opening degree of the electronic expansion valve 502 as the preset opening degree of the electronic expansion valve 502 includes:
2131, obtaining an adjusted opening degree of the electronic expansion valve 502 corresponding to a maximum value of temperature change rates of actual defrosting temperatures of preset defrosting temperatures;
step 2132, calibrating the adjusted opening degree of the electronic expansion valve 502 to the preset opening degree of the electronic expansion valve 502.
In other words, in steps 2131 and 2132, the actual defrosting temperature of the defrosting sensor 504 is recorded for each adjusted opening degree of the electronic expansion valve 502, and the adjusted opening degree of the electronic expansion valve 502 corresponding to the fastest temperature change rate of the actual defrosting temperature obtained by the defrosting sensor 504 is recorded at the same time, where the adjusted opening degree of the electronic expansion valve 502 at this time is the preset opening degree of the electronic expansion valve 502 under the current operating condition.
After the calibration steps, a preset opening degree table of the preset opening degree of the electronic expansion valve 502 shown in the following table can be prepared:
according to an embodiment of the present invention, in calibrating 210 the preset opening degree of the electronic expansion valve 502 based on the preset defrosting temperature, the method further includes:
step 209, adjusting a cold quantity adjusting device of the refrigeration equipment to a preset state, wherein the cold quantity adjusting device comprises at least one of a compressor, a fan and an air door; adjusting the cold quantity adjusting device of the refrigeration equipment to a preset state comprises the following steps: adjusting at least one of the compressor to the maximum rotation speed, the fan to the maximum rotation speed, and the damper to the maximum opening.
In other words, in step 209, the rotation speed of the compressor may be adjusted to the maximum rotation speed, the rotation speed of the fan may be adjusted to the maximum rotation speed, and the opening degree of the damper may be adjusted to the maximum opening degree, so that the refrigeration device is in the state of forced refrigeration.
And a second calibration mode:

In this calibration mode, the method includes:
step 311, adjusting the preset opening degree of the electronic expansion valve 502 to the maximum opening degree and gradually reducing the opening degree;
step 312, obtaining the actual temperature of the refrigerating chamber;
313, determining that the operation condition of the refrigeration equipment meets a preset condition, adjusting the preset opening degree of the electronic expansion valve 502 to an adjusted opening degree, and calibrating the adjusted opening degree of the electronic expansion valve 502 to be the preset opening degree of the electronic expansion valve 502.
Specifically, in step 311, the preset opening degree of the electronic expansion valve 502 is first adjusted to the maximum opening degree, and the preset opening degree of the electronic expansion valve 502 is gradually decreased along with the operation time of the refrigerator;
in step 312, based on the preset opening degrees of the different electronic expansion valves 502, the actual temperature of the refrigeration compartment is obtained through the compartment temperature sensor 508 in the refrigeration compartment;
in step 313, after the operation condition of the refrigerator meets the preset condition, readjusting the preset opening of the electronic expansion valve 502 to the adjusted opening, and after the adjustment is completed, calibrating the adjusted opening of the electronic expansion valve 502 to the preset opening of the electronic expansion valve 502 under the current operation condition.
It should be noted that, in step 313, the operation condition of the refrigerator meeting the preset condition specifically means that the refrigerator is operated to a stable state, and meanwhile, the actual temperature of the refrigeration compartment inside the refrigerator is not reduced any more, which is the preset condition of the refrigerator under the current operation condition.
According to an embodiment of the present invention, in step 313, the step of determining that the operation condition of the refrigeration equipment satisfies the preset condition, adjusting the current preset opening degree of the electronic expansion valve 502 to the adjusted opening degree, and calibrating the adjusted opening degree of the electronic expansion valve 502 as the preset opening degree of the electronic expansion valve 502 includes:
3131, obtaining an adjusted opening degree of the electronic expansion valve 502 corresponding to a maximum value of a temperature change rate of an actual temperature of the cooling compartment;
3132, calibrating the adjusted opening degree of the electronic expansion valve 502 to a preset opening degree of the electronic expansion valve 502.
In other words, in steps 3131 and 3132, the actual temperature of the cooling compartment is recorded for each adjusted opening degree of the electronic expansion valve 502, and the adjusted opening degree of the electronic expansion valve 502 corresponding to the fastest rate of temperature change in the actual temperature of the cooling compartment is recorded, where the adjusted opening degree of the electronic expansion valve 502 at this time is taken as the preset opening degree of the electronic expansion valve 502 in the current operating condition.
