Description
Technical Field
The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration control method of a refrigerator, the refrigerator, a computer device and a computer readable storage medium.
Background
The frequency conversion air-cooled refrigerator can meet the refrigerating capacity requirements of a plurality of refrigerating compartments by regulating and controlling the running rotating speed of the compressor. The existing refrigeration control method of the refrigerator judges the refrigerating capacity requirement of each refrigerating chamber according to the temperature difference value between the detected temperature of each refrigerating chamber and the corresponding preset temperature, and adjusts the running rotating speed gear of a compressor.
However, the control method is not considered from the aspects of the thermal load of the box body and the service life of the compressor, although the operating rotating speed of the compressor meets the requirement of the refrigerating capacity, the control method can cause larger thermal load and larger energy consumption to the box body, for example, after defrosting work is finished, based on the compartment refrigerating requirement, when the compressor is restarted, if the operating rotating speed and the operating duration of the compressor are adjusted only according to the compartment temperature difference, the problems of large thermal load, high energy consumption and the like of the box body exist, and in addition, the problem that the starting failure of the compressor is easily caused due to overhigh system pressure exists.
Disclosure of Invention
The first purpose of the invention is to provide a refrigeration control method of a refrigerator, which meets the compartment refrigeration requirement, solves the heat load and energy consumption of a box body and solves the running problem after defrosting.
The second purpose of the invention is to provide a refrigerator capable of realizing the refrigeration control method.
The third objective of the present invention is to provide a computer device capable of implementing the refrigeration control method.
A fourth object of the present invention is to provide a computer-readable storage medium that can implement the above-mentioned refrigeration control method.
The first purpose of the invention provides a refrigeration control method of a refrigerator, which comprises the steps that when a compressor meets a starting condition, whether the compressor is in a defrosting state at the current moment or not is judged, if not, a first target rotating speed of the compressor is determined according to an obtained outer ring temperature value; if yes, determining a second target rotating speed of the compressor according to the latest defrosting time length.
According to the scheme, when the compressor meets the starting condition, the system judges the state of the compressor at the current moment, and if the compressor does not enter the defrosting state, the system judges whether the compressor is started at the second rotating speed or the third rotating speed by combining the comparison structure of the outer ring temperature value and the first preset value; if the defrosting state is entered firstly, the target rotating speed is selected to be set to be the fourth rotating speed or the second rotating speed according to the latest defrosting time, the starting and stopping time of the compressor is set and matched with the rotating speed of the specific compressor, the temperature change of the freezing chamber meets the refrigeration requirement and functional logic, the running rotating speed and the starting and stopping time of the compressor are also met, the problem of thermal load of a box body is solved, the problem that the compressor cannot be started due to overhigh system pressure after defrosting is finished is solved, the running logic and the rotating speed control of the compressor after defrosting are optimized, the running power of the compressor is ensured to be constant during defrosting, and energy consumption is saved.
The further scheme is that after the step of determining the second target rotating speed according to the latest defrosting time: the compressor operates at a second target rotating speed for a first preset time period; the compressor operates at a second target rotating speed for a second preset time period, and a detection temperature value of the freezing chamber is obtained in real time within the second preset time period; and adjusting the rotating speed of the compressor according to the comparison result of the detected temperature value of the freezing chamber and the second preset value.
Therefore, the rotation speed of the compressor is adjusted under the comprehensive consideration of defrosting requirements, energy consumption and thermal load, the first preset time is operated, and the rotation speed of the compressor is increased according to the room temperature difference value by judging whether the compressor is restarted and judging the current stage of the defrosting state according to the latest defrosting time. For example, at the later stage of the defrosting state or after defrosting is finished, the compressor runs at a lower rotating speed within the dripping time, and the rotating speed of the compressor is increased according to the room temperature difference after the dripping time is finished. For another example, the defrosting device operates at a lower rotating speed in defrosting operation to increase the defrosting amount and enter defrosting in advance, so that the defrosting time is prolonged; and after the frosting state is finished, increasing the rotating speed of the compressor according to the room temperature difference. And when the temperature difference value meets the judgment condition, the system jumps out of the operation logic of the scheme and adjusts the rotating speed of the compressor according to the normal operation logic of the system.
The further scheme is that in the step of adjusting the rotating speed of the compressor according to the comparison result of the detected temperature value of the freezing chamber and the second preset value, the rotating speed after the compressor is adjusted is in positive relation with the latest defrosting time.
Therefore, the longer the defrosting time is last, the larger the temperature difference value between the defrosting rear compartment detection temperature value and the preset value is, the larger the refrigerating demand is, and the rotating speed of the compressor is increased to improve the refrigerating efficiency.
The further scheme is that the second target rotating speed is positively related to the latest defrosting time length, and the second target rotating speed is negatively related to the second preset time length.
Therefore, the longer the defrosting time is, the closer the defrosting state is to be finished or is finished, so that the energy consumption of the heater is lower, the compressor can operate at a higher rotating speed, and the higher the rotating speed of the compressor is, the shorter the required refrigerating time is, so that the second preset time is shortened. The arrangement can improve the compartment refrigeration efficiency under the conditions of energy consumption and heat load.
The method comprises the following steps of firstly, determining a first target rotating speed according to the defrosting time length of the last time, starting a compressor, and operating for a first preset time length: if the last defrosting time is longer than or equal to a third preset value, determining the second target rotating speed as a fourth rotating speed; if the last defrosting time is shorter than a third preset value, determining the second target rotating speed as a second rotating speed; the fourth rotational speed is higher than the second rotational speed.
In a further aspect, the step of operating the compressor at the second target speed for a first preset time period comprises: if the defrosting time of the last time is more than or equal to a third preset value, the value of the first preset time is a first value; if the last defrosting time is less than a third preset value, the value of the first preset time is a second value; the first value is greater than the second value.
Therefore, the current stage is judged according to the comparison result of the latest defrosting time and the third preset value, if the water dropping time is long, the rotating speed of the compressor can be increased to a fourth higher rotating speed and the compressor can operate for a longer time, and if the water dropping time is long, the compressor can be increased to a second lower rotating speed and the compressor can operate for a shorter time, so that the refrigerating efficiency after defrosting can be improved on the premise of avoiding over-high energy consumption.
The further scheme is that in the step that the compressor runs at a second target rotating speed for a second preset time period: if the defrosting time of the last time is more than or equal to a third preset value, taking the value of the second preset time as a third value; if the last defrosting time is shorter than a third preset value, the value of the second preset time is a fourth value; the third value is less than the fourth value.
As can be seen from the above, under the same refrigeration requirement, the higher the rotation speed of the compressor is, the shorter the required refrigeration time period is, and thus the second preset time period is shortened. The arrangement can improve the compartment refrigeration efficiency under the conditions of energy consumption and heat load.
The further scheme is that the step of adjusting the rotating speed of the compressor according to the comparison result of the detected temperature value of the freezing chamber and the second preset value is as follows: when the last defrosting time is longer than or equal to a third preset value, and the difference value between the detected temperature value of the freezing chamber and the second preset value is longer than or equal to a fourth preset value, increasing the rotating speed of the compressor to an eighth rotating speed; when the last defrosting time is shorter than a third preset value and the difference value between the detected temperature value of the freezing chamber and the second preset value is larger than or equal to a fifth preset value, the rotating speed of the compressor is increased to a seventh rotating speed; the fourth preset value is larger than the fifth preset value, and the eighth rotating speed is higher than the seventh rotating speed.
As can be seen from the above, according to the difference of the last defrosting time, the preset values used for comparing the difference between the detected temperature value of the freezing chamber and the second preset value are different, and correspondingly, the selection of the increased speed gear is different, so as to better judge the temperature change of the freezing chamber to match the corresponding speed of the compressor.
The further scheme is that the step of adjusting the rotating speed of the compressor according to the comparison result of the detected temperature value of the freezing chamber and the second preset value is as follows: when the last defrosting time is longer than or equal to a third preset value and the difference value between the detected temperature value of the freezing chamber and the second preset value is smaller than a fourth preset value, the rotating speed of the compressor is kept at a fourth rotating speed; and when the last defrosting time is less than a third preset value and the difference value between the detected temperature value of the freezing chamber and the second preset value is less than a fifth preset value, the rotating speed of the compressor is kept at the second rotating speed.
Therefore, if the difference value between the detected temperature value of the freezing chamber and the second preset value is smaller than the corresponding preset value, the current rotating speed of the compressor is judged to meet the refrigeration requirement, and therefore the rotating speed is not increased so as to reduce energy consumption and heat load of the box body.
After the step of increasing the rotating speed of the compressor to the eighth rotating speed, if the difference value between the detected temperature value of the freezing chamber and the second preset value is greater than or equal to the sixth preset value, adjusting the rotating speed of the compressor according to the initial refrigeration requirement; after the step of increasing the rotating speed of the compressor to the seventh rotating speed, if the difference value between the detected temperature value of the freezing chamber and the second preset value is larger than or equal to the seventh preset value, the rotating speed of the compressor is adjusted according to the initial refrigeration requirement. The sixth preset value is smaller than the fourth preset value, and the seventh preset value is smaller than the fifth preset value.
Therefore, by setting the second temperature difference value judging step, whether the room temperature meets the requirement after the rotating speed of the compressor is increased and operates for a certain time is judged, and if yes, the rotating speed of the compressor is reduced according to the required rotating speed of the initial refrigeration state.
The further scheme is that the step of determining the first target rotating speed according to the obtained outer ring temperature value comprises the following steps: if the outer ring temperature value is larger than or equal to a first preset value, the first target rotating speed is determined as a second rotating speed; if the outer ring temperature value is smaller than the first preset value, the first target rotating speed is determined as a third rotating speed; the third rotational speed is higher than the second rotational speed.
The first target rotating speed is determined as the second rotating speed and then runs for a third preset time; the first target rotating speed is determined as a third rotating speed and then runs for a fourth preset time; the third preset duration is greater than the fourth preset duration.
Therefore, if the compressor is not started after entering the defrosting state, the heat load condition of the current box body is judged according to the difference value between the outer ring temperature value and the first preset value, if the heat load of the box body is large, the compressor runs for a long time at a low rotating speed to meet the refrigerating capacity requirement, if the heat load of the box body is small, the compressor runs for a long time at a high rotating speed to meet the refrigerating requirement, and therefore the situation that the heat load of the box body is too high is avoided.

The refrigerating system of the refrigerator comprises a compressor, wherein the rotating speed of the compressor can be controlled, 8 levels of rotating speeds such as L1-L8 are preset for the rotating speed of the compressor, the rotating speeds are sequentially increased from the level L1 to the level L8, and the rotating speeds from the level L1 to the level L8, the L1 rotating speed, the L2 rotating speed and the L3 rotating speed … … and the L8 rotating speed respectively correspond to a first rotating speed, a second rotating speed and a third rotating speed … … and an eighth rotating speed.
A processor is provided in the housing of the refrigerator for implementing the refrigeration control method when executing the computer program stored in the memory.
Referring to fig. 1, a refrigeration control method of a refrigerator is as follows:
after the refrigerator is powered on, the system first performs a determining step S1 to determine whether the compressor satisfies the power-on condition, and a determining step S1 is used to determine whether the compressor satisfies the basic condition for restarting. If the judgment result of the step S1 is negative, the process proceeds to step S20, and the operation of the compressor is controlled according to the initial cooling state request. If the determination result in the step S1 is yes, a determination step S2 is executed to determine whether the compressor enters the defrosting state before the current time point of restarting the compressor after determining whether the compressor enters the defrosting state at the current time point. Since whether the defrosting state is entered before the current time affects the energy consumption and the heat load condition of the system, different target rotating speeds of the compressor need to be set as the judgment conditions.
If the judgment result in the step S2 is no, executing step S16, obtaining an outer ring temperature value t10 in real time, and then executing a judgment step S17, judging whether the outer ring temperature value t10 is greater than a first preset value t1, where t1 is 16 ℃ in this embodiment, if the judgment result in the step S17 is yes, executing step S18, where the compressor determines that the L2 rotation speed is started as the target rotation speed and operates for 60 seconds, and 60 seconds is a third preset duration of the present invention; if the judgment result in the step S17 is negative, step S19 is executed, and the compressor determines that the L3 rotation speed is started as the target rotation speed, and the operation is performed for 40 seconds, where 40 seconds is a fourth preset time period of the present invention. Because the outer ring temperature value can reflect the heat load condition of the box body, different target rotating speeds of the compressor are set according to the difference value of the outer ring temperature value and the first preset value, and the heat load of the box body is reduced.
If the judgment result of the judgment step S2 is yes, a judgment step S3 is executed to judge whether the latest defrosting time length a from the time of entering the defrosting state is greater than or equal to 30 minutes, and the 30 minutes is a third preset value of the present invention.
If the judgment result in the step S3 is yes, step S4 is executed, and the compressor determines that the rotation speed of the L4 is the target rotation speed, starts and operates for 10 minutes, where 10 minutes is a first value of a first preset time period of the present invention. Since the last defrosting time period a exceeds 30 minutes, the defrosting state may have been exited or the heater may be in the dripping time and the defrosting state is about to exit, and the heater has stopped operating, the compressor may be started at the higher L4 speed and 10 minutes may be set as the dripping time period.
With reference to fig. 1 and fig. 2, after step S4 is completed, step S5 is executed, the rotation speed of the compressor is maintained at L4 and the compressor runs for 60 minutes, and meanwhile, the detected temperature value t11 of the freezing chamber is obtained in real time, and 60 minutes is a third value of a second preset time period of the present invention. In the step, the compressor is maintained at a lower rotating speed and runs for a longer time to defrost, and then the compressor is recovered, so that the problem that the compressor cannot be started due to direct starting at a high rotating speed after the defrosting state is finished can be solved.
Then, executing a judgment step S6, judging whether the difference between the detected freezing chamber temperature value t11 and the second preset value t2 is greater than or equal to a fourth preset value t4, where in this embodiment, the fourth preset value t4 is 4 ℃, and if not, the current L4 rotation speed meets the refrigeration requirement, executing a step S9, and keeping the rotation speed of the compressor at L4 and continuing to operate; if yes, the current L4 speed does not match the cooling demand, and step S7 is executed, where the compressor speed is increased to the L8 speed and the operation is performed.
And executing a circulating judgment step S8 after the rotating speed is increased, judging whether the difference value between the detected freezing chamber temperature value t11 and the second preset value t2 is larger than or equal to a sixth preset value t6, wherein the sixth preset value t6 is equal to-1 ℃ in the embodiment, if not, executing a step S8 in a circulating mode, if so, meeting the refrigeration requirement, and then executing a step S20, and controlling the compressor to operate according to the initial refrigeration state requirement.
Referring to fig. 1, if the determination result in the step S3 is negative, step S10 is executed, the compressor determines that L2 is started at the target rotation speed, the compressor runs for 8 minutes, and 8 minutes is a second value of the first preset time period of the present invention. Because the defrosting time A of the last defrosting does not exceed 30 minutes, the defrosting state is not exited and the evaporator is in a precooling stage, the compressor is started at a low L2 rotating speed, 8 minutes are set as precooling time, the defrosting amount of the upper surface and the lower surface of the fin evaporator is accelerated, the defrosting process is started in advance, and the working time of the heater is prolonged.
With reference to fig. 1 and 3, after the step S10 is completed, step S11 is executed, the rotation speed of the compressor is maintained at L2, the compressor runs for 80 minutes, and meanwhile, a detected temperature value t11 of the freezing chamber is obtained in real time, and 80 minutes is a fourth value of a second preset time period of the present invention. In the step, the compressor is maintained at a lower rotating speed and operates for a longer time to defrost, and then the compressor is recovered, so that the problem that the compressor is started at a high rotating speed again due to the increase of refrigerating capacity after the defrosting process is finished is solved.
Then, executing a judgment step S12, judging whether the difference between the detected freezing chamber temperature value t11 and the second preset value t2 is greater than or equal to a fifth preset value t5, where in this embodiment, the fourth preset value t5 is 3 ℃, and if not, the current L2 rotation speed meets the refrigeration requirement, executing a step S15, and keeping the rotation speed of the compressor at L2 and continuing to operate; if yes, the current L2 speed does not match the cooling demand, and step S13 is executed, where the compressor speed is increased to the L7 speed and the operation is performed.
And executing a circulating judgment step S14 after the rotating speed is increased, judging whether the difference value between the detected freezing chamber temperature value t11 and the second preset value t2 is greater than or equal to an eighth preset value t8, wherein the eighth preset value t8 is-2 ℃ in the embodiment, if not, executing a step S14 in a circulating mode, if so, meeting the refrigeration requirement, and then executing a step S20, and controlling the compressor to operate according to the initial refrigeration state requirement.
With reference to fig. 1 to 3, in the present invention, when the compressor meets the start condition, the system first determines the current state, and if the compressor does not enter the defrosting state, the system determines whether the compressor is started at the second rotation speed or the third rotation speed by combining the comparison structure between the outer ring temperature value and the first preset value; if the defrosting state is entered firstly, the target rotating speed is selected and set to be the fourth rotating speed or the second rotating speed according to the latest defrosting time, after the corresponding preset time is operated, whether the rotating speed of the compressor needs to be increased or not is judged according to the compartment detection temperature, and if the rotating speed of the compressor needs to be increased, the rotating speed of the compressor is correspondingly increased to be the eighth rotating speed or the seventh rotating speed.
According to the invention, by setting the on-off time of the compressor and matching the rotating speed of the specific compressor, the temperature change of the freezing chamber meets the refrigeration requirement and functional logic, and also meets the operating rotating speed and the on-off time of the compressor, the problem of thermal load of a box body is solved, the problem that the compressor cannot be started due to overhigh system pressure after defrosting is finished is solved, the operating logic and rotating speed control of the compressor after defrosting are optimized, the operating power of the compressor is ensured to be constant during defrosting, and the energy consumption is saved.
