Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The following describes a water supercooling recognition method and device for a refrigeration apparatus and the refrigeration apparatus according to an embodiment of the present application with reference to the drawings.
Fig. 1 is a flowchart of a water supercooling recognition method of a refrigeration apparatus according to an embodiment of the present application. As shown in fig. 1, the method specifically comprises the following steps:
s101, controlling refrigeration equipment to refrigerate water.
Alternatively, the refrigeration device may be controlled to read a user-input command for controlling the refrigeration device to refrigerate the water. The user can manually input through an operation panel, a remote controller and the like or remotely input a command for controlling the refrigeration equipment to refrigerate water through voice.
S102, continuously detecting the water temperature of water in the refrigeration equipment, acquiring the time for reaching the water temperature, and acquiring the water temperature change rate according to the water temperature and the time.
It should be noted that, a water temperature sensor is provided in the present application, and the water temperature sensor can acquire the water temperature of the water in the refrigeration equipment in real time or periodically.
Alternatively, the water temperature of the water in the plant may be continuously monitored, the time to reach the water temperature may be obtained, and the marking may be performed sequentially after the water temperature and the time are obtained. For example, the water temperatures T1, T2, T3 to Tn and the times T1, T2, T3 to Tn are obtained and marked in sequence by a water temperature sensor. Where Tn is the time to reach temperature Tn.
Further, after the current water temperature, the water temperature T (n-1) at the previous time, the current time tn, and the time T (n-1) at the previous time are obtained, the water temperature change rate may be calculated according to a functional relationship between the water temperature and the time, for example, the functional relationship is: kn ═ Tn-T (n-1))/(Tn-T (n-1)), and the like, and the rate of change in water temperature was obtained and sequentially labeled. For example, the water temperature change rates k1, k2, k 3-kn can be obtained and marked sequentially. Where kn is the rate of change of water temperature at time Tn of Tn.
S103, detecting that the water temperature reaches a preset value.
Alternatively, after the water temperature of the water is acquired, the water temperature may be compared with a preset value. If the water temperature is identified to reach the preset value, the step S104 is further executed; and if the identified water temperature does not reach the preset value, returning to the step S102. Wherein the preset value is zero degrees centigrade.
And S104, judging whether the supercooling phenomenon occurs or not according to the water temperature change rate.
In practical applications, when the refrigeration equipment tries to make ice, filtered water is generally used as a raw material in order to make the ice made by the refrigeration equipment available for direct consumption by users. However, the higher the purity of water, the more likely a phenomenon in which the actual crystallization temperature is lower than the theoretical crystallization temperature, i.e., a supercooling phenomenon, occurs. That is, the characteristic state of water is still liquid when the critical temperature for crystallization (0 ℃) is reached. For example, High purity water (High purity water) is water from which impurities other than dielectrics are removed, and is too pure, has no "crystal nuclei" required for solidification, and is easily supercooled, so that the High purity water begins to freeze at-40 ℃.
Generally, when the water temperature reaches the critical temperature (0 ℃), freezing will continue to occur, and freezing will continue to occur during the continuous refrigeration process of the refrigeration equipment, so that a variation trend like the first curve segment in fig. 2(a) is formed. During this time, the water gradually and completely transforms from liquid water to solid ice over time, the water temperature being kept close to 0 ℃.
After all the water in the refrigeration unit has frozen completely, continued refrigeration will result in a tendency to drop in temperature forming the second curve segment in fig. 2 (a). During this time, the solid ice state is maintained and the water temperature continues to drop from near 0 ℃ to below 0 ℃ over time. Fig. 2(a) is a temperature change curve of water in which supercooling does not occur.
In the refrigeration equipment, due to the supercooling phenomenon, the temperature of the unfrozen liquid is continuously reduced, and the continuous refrigeration at this time causes the trend of the temperature reduction forming the first curve segment in fig. 2 (b). During this time, the water remains liquid over time and the temperature of the water continues to drop below zero, at a minimum of-40 ℃. Fig. 2(b) is a temperature change curve of water in which a supercooling phenomenon occurs.
Further, by means of improving the refrigerating capacity of the refrigerating equipment and the like, the water in the supercooled state gradually begins to freeze, and redundant heat is discharged in the freezing process due to the reduction of the liquid molecular distance, so that the heat is released when the water freezes. At this time, there is a small temperature rise of the overall water temperature, which is a trend of the second curve segment in fig. 2 (b).
Based on the point, after the water temperature change rate is obtained, whether the supercooling phenomenon occurs or not can be identified according to the change trend of the water temperature change rate.
Fig. 3(a) and (b) are graphs showing the time-dependent change rate of the water temperature and the temperature, respectively, in the case where supercooling does not occur and in the case where supercooling occurs.
As shown in fig. 3(a), in the case where supercooling does not occur, three stages are divided: in the first stage, the water temperature is reduced to 0 ℃ from the beginning of refrigeration of the refrigeration equipment, and the water temperature change rate is a negative value in the period; the second stage, when the temperature of the water is reduced to 0 ℃, the refrigeration is continued, the water is converted from liquid state into solid ice, because the water temperature is maintained to be close to 0 ℃, the change rate of the water temperature is zero or a negative value close to zero at the moment, but is obviously greater than the change rate of the water temperature when the supercooling phenomenon occurs compared with the change rate of the water temperature when the supercooling phenomenon occurs, for example, the change rate of the water temperature when the supercooling phenomenon does not occur is 0 or-0.01, and the change rate of the water temperature when the supercooling phenomenon occurs is-0.75; and in the third stage, when the water is completely frozen, the refrigeration is continued, the temperature of the ice blocks is continuously reduced, and the water temperature change rate is a negative value. It can be seen that the absolute value of the rate of change of the water temperature during the second stage is significantly less than the first and third periods of time and is zero or close to zero. The stage can be determined by detecting the water temperature value, for example, the first stage is from the initial water temperature value to the first detection that the water temperature value is 0 ℃, the second stage is when the water temperature value is maintained near 0 ℃, and the third stage is when the water temperature continues to drop below zero.
As shown in fig. 3(b), the supercooling occurs, and is also divided into three stages: in the first stage, the water temperature is reduced to 0 ℃ from the beginning of refrigeration of the refrigeration equipment, and the water temperature change rate is a negative value in the period; in the second stage, when the temperature of water is reduced to 0 ℃, the refrigeration is continued, the water can be kept in a liquid state, the temperature of the water can be reduced to be nearly-40 ℃ at the lowest point, in the second stage, the water is always in the liquid state, the water temperature change rate is an obvious negative value, and the water temperature change rate is obviously smaller than zero in the second stage when the supercooling phenomenon does not occur; and in the third stage, the refrigeration is continued, the water in the supercooled state is solidified into ice blocks from the liquid state, heat is released, the temperature rises again, and the water temperature change rate in the stage is positive. The determination of the stage can be realized by detecting the water temperature value, for example, the water temperature value continuously decreases to the second stage from the initial water temperature value to the first stage when the water temperature value is detected to be 0 ℃, and the water temperature value starts to increase to the third stage again.
It can be seen that, comparing fig. 3(a) and fig. 3(b), it can be determined whether the water is supercooled by detecting the rate of change of the temperature of the water in the second stage. When the water temperature change rate is 0 or close to 0, the water is converted from liquid state into solid ice at the time, and supercooling does not occur; when the water temperature change rate is obviously less than 0, the water keeps liquid at the moment, and supercooling occurs. The water temperature change rate is detected by judging the water temperature change rate of the second stage, namely starting from the water temperature reaching 0 ℃, and whether supercooling occurs or not can be judged by the numerical value of the water temperature change rate.
Similarly, comparing fig. 3(a) and 3(b), it is possible to determine whether the supercooled water state has been released by detecting the rate of change of the water temperature at the third stage. When the change rate of the water temperature is changed from a negative value to a positive value, the supercooled water is condensed into ice, and the supercooled state of the water is relieved; when the water temperature change rate is always negative, it indicates that no supercooling has occurred.
Therefore, the method and the device can obtain the water temperature change rate by detecting the water temperature of the water in the refrigeration equipment and the time for reaching the temperature, dynamically identify whether the supercooling phenomenon occurs or not according to the change trend of the water temperature change rate after the detected water temperature reaches the preset value, and can timely and accurately identify the supercooling phenomenon, thereby reducing the time for the supercooling phenomenon in the refrigeration process of the refrigeration equipment in the prior art as far as possible, and improving the ice making efficiency and quality of the refrigeration equipment.
On the basis of the embodiment, after the supercooling phenomenon is judged to occur, the water temperature of the refrigeration equipment water can be continuously detected to judge whether the supercooling phenomenon is eliminated, so that the safety problem or the energy consumption problem caused by continuous supercooling can be avoided. As a possible implementation manner, as shown in fig. 4, the method specifically includes the following steps:
s201, detecting the water temperature of water at certain time intervals, and continuously updating the value of the water temperature change rate according to the water temperature and the time reaching the water temperature.
After the supercooling phenomenon is judged to occur, the refrigeration equipment can continue the refrigeration operation according to the current refrigeration operation parameters in order to remove the supercooling phenomenon, so that the water in the supercooled state is frozen. Optionally, the refrigerating capacity of the refrigerating equipment is enhanced to accelerate the speed of the water in the refrigerating equipment when the water is changed from a liquid state to a solid state, so that the supercooling phenomenon is relieved quickly. The mode of enhancing the refrigerating capacity can be set according to actual conditions. For example, the cooling capacity of the cooling device can be increased by increasing the air output of the cooling device.
S202, judging whether the supercooling phenomenon is relieved or not according to the updated water temperature change rate.
Alternatively, if it is recognized that the updated water temperature change rate is greater than zero, step S203 may be performed; otherwise, the process may return to step S201.
And S203, judging that the supercooling phenomenon is relieved.
And S204, controlling the refrigeration equipment to perform ice separating action.
According to the method and the device, the supercooling phenomenon can be determined, the refrigerating capacity of the refrigerating equipment is enhanced while refrigeration is continuously carried out, the updated water temperature change rate is judged, if the water temperature change rate is identified to be larger than zero, the situation that all liquid in the refrigerating equipment is frozen is shown, the supercooling phenomenon can be judged to be relieved, and the refrigerating equipment can be further controlled to execute ice separating action.
Therefore, after the supercooling phenomenon is judged to occur, the water temperature of the water is detected at certain time intervals, the value of the water temperature change rate is continuously updated according to the water temperature and the time reaching the water temperature, whether the supercooling phenomenon is relieved or not is judged according to the updated water temperature change rate, and after the supercooling phenomenon is relieved, the fact that liquid water does not exist in the refrigerating equipment is determined, the refrigerating equipment is controlled to perform ice separating action after the liquid water is solid ice, so that after the supercooling phenomenon occurs, the supercooling phenomenon can be improved by improving the refrigerating capacity of the refrigerating equipment, and the auxiliary solidification equipment does not need to be additionally arranged to promote liquid to be converted into solid. Simultaneously, can also ensure that the ice that the user took all has good quality, promote user experience. Furthermore, the ice making period of the refrigeration equipment can be greatly shortened by quickly and accurately judging whether the supercooling phenomenon occurs or not and whether the supercooling phenomenon is removed or not.
In order to implement the above embodiments, the present application further provides a flowchart of another method for identifying water supercooling in a refrigeration device. As shown in fig. 5, the method specifically includes the following steps:
s301, controlling refrigeration equipment to refrigerate water.
S302, continuously detecting the water temperature of water in the refrigeration equipment, acquiring the time for reaching the water temperature, and acquiring the water temperature change rate according to the water temperature and the time.
S303, judging whether the water temperature reaches a preset value.
Alternatively, after the water temperature of the water is acquired, the water temperature may be compared with a preset value. If the water temperature is recognized to reach the preset value, the step S304 is further executed; if the recognized water temperature does not reach the preset value, the process returns to step S302.
S304, judging whether the water temperature change rate is smaller than zero.
Alternatively, if it is recognized that the water temperature change rate is less than zero, step S305 may be performed; otherwise, judging that the supercooling phenomenon does not occur.
S305, judging that the supercooling phenomenon occurs.
S306, detecting the water temperature of the water at certain time intervals, and continuously updating the value of the water temperature change rate according to the water temperature and the time reaching the water temperature.
And S307, judging whether the water temperature change rate is greater than zero according to the updated water temperature change rate.
Alternatively, if it is recognized that the water temperature change rate is greater than zero, step S308 may be performed; otherwise, the process returns to step S306.
And S308, judging that the supercooling phenomenon is relieved.
And S309, controlling the refrigeration equipment to perform ice separating action.
Optionally, after it is determined that the supercooling phenomenon is removed, it is determined that all water in the refrigeration apparatus has frozen from liquid to ice, and the ice at this time has reached a preset thickness, the refrigeration apparatus may be controlled to drop the ice from the evaporator, so that the refrigeration apparatus further performs an ice making process of a next cycle until the ice in the refrigeration apparatus is accumulated to a preset ice amount.
Therefore, the method and the device can obtain the water temperature change rate by detecting the water temperature of the water in the refrigeration equipment and the time for reaching the temperature, dynamically identify whether the supercooling phenomenon occurs or not according to the change trend of the water temperature change rate after the detected water temperature reaches the preset value, and can timely and accurately identify the supercooling phenomenon, thereby reducing the time for the supercooling phenomenon in the refrigeration process of the refrigeration equipment in the prior art as far as possible, and improving the ice making efficiency and quality of the refrigeration equipment.
