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:
step 200, adjusting the actual opening degree of the electronic expansion valve 102 according to the actual difference between the return air temperature of the evaporator 100 and the actual ambient temperature.
According to the control method of the refrigeration equipment in the embodiment of the first aspect of the present invention, a larger refrigerant flow rate can be obtained only by obtaining the actual difference between the return air temperature of the evaporator 100 and the actual ambient temperature, and then adjusting the actual opening of the electronic expansion valve 102 according to the actual difference between the return air temperature of the evaporator 100 and the actual ambient temperature, that is, in this process, no additional introduction of other environmental variables is required, and only one evaporated return air temperature sensor 101 capable of acquiring the return air temperature of the evaporator 100 needs to be provided, so that the flow rate of the refrigerant can be adjusted in real time along with the change of the actual working condition of the refrigeration equipment, and the refrigeration equipment is ensured to be in a better rapid refrigeration state. By using the electronic expansion valve 102 in the refrigeration equipment, the flow rate 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, in step 100, the return air temperature of the evaporator 100 can be obtained by an evaporation return air temperature sensor 101 disposed at the position of the evaporator 100, and the actual ambient temperature can be obtained by a temperature sensor of the refrigeration equipment.
After the return air temperature of the evaporator 100 and the actual ambient temperature of the location where the refrigeration equipment is located are obtained, the actual difference between the return air temperature of the evaporator 100 and the actual ambient temperature is obtained through calculation by the control system 105.
In step 200, the actual opening degree of the electronic expansion valve 102 is adjusted according to the actual difference between the return air temperature of the evaporator 100 and the actual ambient temperature.
In this step, if the actual difference between the return air temperature of the evaporator 100 and the actual ambient temperature is greater than the preset difference, the actual opening degree of the electronic expansion valve 102 is decreased accordingly. In other words, the electronic expansion valve 102 serves as a throttle device that can adjust the flow rate and the evaporation temperature of the refrigerant. As the temperature of the refrigeration compartment decreases, the temperature difference between the temperature of the evaporator 100 and the temperature of the refrigeration compartment decreases, the heat exchange capacity of the evaporator 100 decreases, and the excess cold is discharged along with the return air of the compressor 104, thereby causing waste of the cold. When the opening degree of the electronic expansion valve 102 is decreased from large to small, the flow rate is decreased, and the evaporation temperature of the refrigerant is decreased; as the refrigeration equipment continues to operate, the refrigerant flow rate needs to be reduced to lower the evaporation temperature, so the rapid refrigeration process is a process in which the opening degree of the electronic expansion valve 102 is continuously reduced.
After the actual opening degree of the electronic expansion valve 102 is adjusted, the return air temperature and the ambient actual temperature of the evaporator 100 are collected again at regular intervals, whether the refrigeration equipment reaches the target temperature value or not is judged, and whether the rapid refrigeration mode needs to be exited or not is judged. If the refrigeration equipment does not reach the target temperature value, i.e. it is proved that the fast cooling mode does not need to be exited, the steps 100 and 200 are repeated.
According to an embodiment of the present invention, the step of adjusting the actual opening degree of the electronic expansion valve 102 according to the actual difference between the return air temperature of the evaporator 100 and the actual ambient temperature comprises:
step 201, calibrating a preset difference value between the return air temperature of the evaporator 100 and an environment preset temperature;
step 202, determining that the actual difference is larger than a preset difference, and reducing the actual opening.
That is, in step 201, the preset difference between the return air temperature of the evaporator 100 and the preset environment temperature needs to be calibrated according to the return air temperature of the evaporator 100 and the preset environment temperature.
In step 202, it is determined whether an actual difference between the return air temperature of the evaporator 100 and the actual ambient temperature is greater than a preset difference, and if the actual difference is greater than the preset difference, the actual opening of the electronic expansion valve 102 is decreased so that the operating condition of the refrigeration equipment can meet the usage requirement of rapid refrigeration.
In the following, a calibration method for a preset difference between a return air temperature of the evaporator 100 and an environmental preset temperature provided in an embodiment of the present invention is described, in the embodiment of the present invention, at least the following three calibration manners may be adopted for calibration of the preset difference:
the calibration method is as follows:
in this calibration mode, the reduction of the preset temperature of the matching environment reduces the preset difference. That is, as the preset ambient temperature decreases, the preset difference between the return air temperature of the evaporator 100 and the preset ambient temperature is decreased accordingly.
As shown in the following table, the environmental preset temperature may be set to several different temperature intervals, and the preset difference between the return air temperature of the evaporator 100 and the environmental preset temperature may be calibrated according to the temperature intervals.
And a second calibration mode:
in this calibration mode, the preset difference is increased in accordance with the decrease in the preset opening degree of the electronic expansion valve 102. That is, as the preset opening degree of the electronic expansion valve 102 decreases, the preset difference between the return air temperature of the evaporator 100 and the environmental preset temperature is increased.
As shown in the following table, the preset opening degree of the electronic expansion valve 102 may be set to several different opening degree intervals, and the preset difference between the return air temperature of the evaporator 100 and the environment preset temperature may be calibrated according to the opening degree intervals.
A third calibration mode:
in this calibration mode, the preset difference is decreased in accordance with a decrease in the preset temperature of the environment, and the preset difference is increased in accordance with a decrease in the preset opening degree of the electronic expansion valve 102.
As shown in the following table, the preset ambient temperature may be taken as an abscissa for calibrating the preset difference, the preset opening degree of the electronic expansion valve 102 may be taken as an ordinate for calibrating the preset difference, and the preset difference between the return air temperature of the evaporator 100 and the preset ambient temperature may be calibrated according to the preset ambient temperature and the preset opening degree of the electronic expansion valve 102.

step 10, adjusting a cold quantity adjusting device of the refrigeration equipment to a preset state, wherein the cold quantity adjusting device comprises a compressor 104 and/or a fan; adjusting the cold quantity adjusting device of the refrigeration equipment to a preset state comprises the following steps: adjusting the compressor 104 to a maximum speed and/or adjusting the fan to a maximum speed.
Specifically, in the three different calibration modes, the rotation speed of the compressor 104 may be adjusted to the maximum rotation speed, and the rotation speed of the fan may be adjusted to the maximum rotation speed, so that the refrigeration device can be ensured to be in a forced refrigeration state.
