Referring to fig. 1 and 6, a control method of a refrigeration appliance 200 according to an embodiment of the present invention includes:
the rotational speed of the compressor 12 is controlled according to the deviation of the operation curve from the control setting curve.
The control method of the refrigeration appliance 200 can control the rotation speed of the compressor 12 according to the deviation between the operation curve and the control setting curve, wherein the operation curve is determined by the second room temperature change rate and the indoor temperature, the control setting curve is determined by the first change curve of the room temperature change rate of the compressor 12 along with the indoor temperature in the shutdown time, and therefore the model and the scene applicable to the control method can be enlarged, and the self-adaptive learning is realized, and the application range is wide. In addition, the control method can automatically adjust the rotating speed of the compressor 12 according to the indoor temperature and the set temperature of the compartment, thereby reducing the operation energy consumption of the refrigeration appliance 200.
Specifically, the refrigeration appliance 200 includes, but is not limited to, a refrigerator, a freezer, and the like refrigeration appliance 200. The refrigerator 200 includes a compartment for receiving food, a compressor 12, and a door body that can open and close an opening of the compartment. The compressor 12 is located outside the compartment, and the compressor 12 may be used to cool the space within the compartment to allow food to be placed for a longer period of time.
The refrigerator 200 may further include a control board for controlling the overall operation of the refrigerator 200, the control board for monitoring the temperature of the compartment, and when the temperature of the compartment reaches a certain temperature value, the control board may control the start-up or stop of the compressor 12, and by recording the start-up time and stop time of the compressor 12, the start-up time and stop time of the compressor 12 may be obtained. The chamber temperature can be obtained by a bulb.
The change rate of the inter-room temperature with the indoor temperature is an important sign of the operation of the refrigeration system of the refrigeration appliance 200, and the optimal change rate of the inter-room temperature of the compressor 12 during the start-up time is related to the change rate of the inter-room temperature during the stop time, so that the second change curve of the compressor 12 during the start-up time can be obtained according to the first change curve of the compressor 12 during the stop time. The correlation relationship can be preset and calibrated and stored.
The compartment set temperature may be a compartment temperature set by a user or a compartment temperature set by the refrigerator 200 according to a program setting, which is not particularly limited herein. The indoor temperature may be an ambient temperature in which the refrigerator 200 is located, and may be acquired by an ambient temperature sensor.
In one embodiment, the first chamber temperature rate of change may be an average rate of change of the chamber temperature of the compressor 12 during the downtime, and the second chamber temperature rate of change may be an average rate of change of the chamber temperature of the compressor 12 during the on-time.
The first change curve may be generated by acquiring a plurality of first room temperature change rates and a plurality of room temperatures for a period of time after installation of the refrigerator. For example, the first profile may be obtained within two weeks after installation of the refrigerator. This process corresponds to a learning phase.
In one embodiment, the operating curve may be acquired over a period of time after the first change curve is generated. For example, the operating profile may be obtained over a period of time after two weeks after installation of the refrigerator. In one example, the running curve of the temperature change rate of the indoor temperature along with the indoor temperature of the newly collected compressor in the starting time is calculated within one month after the refrigerating appliance is installed for two weeks, and then the rotating speed of the compressor is controlled according to the deviation of the running curve and the control setting curve.
In certain embodiments, step 103 comprises:
determining a temperature range according to the compartment set temperature during the start-up time of the compressor 12 and the stop time of the compressor 12, respectively;
determining a first temperature and a second temperature in a temperature range, and a first time corresponding to the first temperature and a second time corresponding to the second temperature;
and determining the first room temperature change rate and the second room temperature change rate according to the first temperature, the second temperature, the first time and the second time.
In this way, erroneous judgment of the control method can be reduced.
Specifically, the first and second temperatures, and the respective first and second times, are determined during the on-time and off-time of the compressor 12, respectively, and within a range around the chamber set temperature to calculate the chamber temperature change rate.
Referring to fig. 2, the second inter-chamber temperature change rate dtdtdtk= (Tk 2-Tk 1)/(Tk 2-Tk 1), wherein Tk1 represents a first temperature determined in a temperature range during a start-up time of the compressor 12, tk2 represents a second temperature determined in the temperature range during the start-up time of the compressor 12, tk1 represents a first time corresponding to the first temperature Tk1, and Tk2 represents a second time corresponding to the second temperature Tk 2.
A first compartment temperature change rate dtdtdttg= (Tg 2-Tg 1)/(Tg 2-Tg 1), wherein Tg1 represents a first temperature determined in a temperature range during a stop time of the compressor 12, tg2 represents a second temperature determined in a temperature range during a stop time of the compressor 12, tg1 represents a first time corresponding to the first temperature Tg1, and Tg2 represents a second time corresponding to the second temperature Tg 2.
The temperature range is determined according to the compartment set temperature, and the temperature value is selected in the temperature range to calculate the compartment temperature change rate, so that misjudgment of a control method is reduced, and particularly, the influence on the control method after the compartment temperature fluctuates in a large range due to the fact that the compressor 12 is started under the following three conditions can be avoided:
a) The refrigeration appliance 200 is operated for the first time;
b) After the user opens and closes the door body of the refrigeration appliance 200;
c) And after defrosting of the refrigerator.
In some embodiments, the temperature range is a temperature range centered around a set temperature of the chamber.
In this way, erroneous judgment of the control method can be further reduced.
Specifically, the temperature ranges may include a first temperature range corresponding to a shutdown time of the compressor 12 and a second temperature range corresponding to a startup time of the compressor 12. The second temperature range may be determined during the on-time of the compressor 12 and within a range of set temperatures around the compartment (e.g., plus or minus 1 degree). The first temperature range may be determined during the downtime of the compressor 12 and within a range of temperatures (e.g., plus or minus 1 degree) set around the compartment.
In one example, the chamber is set to a temperature of-18 degrees, and the determined first and second temperature ranges are each [ -17 degrees, -19 degrees ], -18 degrees being centered in the temperature range. It will be appreciated that the first and second temperature ranges may be the same or different.
It is to be understood that in other embodiments, the temperature range is not limited to a temperature range centered on the set temperature of the chamber, and may be other temperature ranges as long as the temperature range includes the set temperature of the chamber.
In certain embodiments, step 105 comprises:
and obtaining a first change curve by using the first room temperature change rate and the room temperature in a fitting mode.
Therefore, the first change curve acquisition method is simple and feasible, and the efficiency of the control method is improved.
Specifically, referring to fig. 3, by acquiring the indoor temperature and calculating the first room temperature change rate of the compressor 12 during the downtime, the relationship between the first room temperature change rate and the indoor temperature is obtained, by establishing a coordinate system with the abscissa being the indoor temperature IAT and the ordinate being the first room temperature change rate dtdtdttg, the relationship data points of the first room temperature change rate and the indoor temperature can be obtained, and by fitting to a plurality of relationship data points, the first change curve can be obtained. In fig. 3, the first curve a obtained by fitting is a straight line, and as the indoor temperature increases, the first room temperature change rate increases.
It will be appreciated that in other embodiments, the first variation curve is not limited to the form of a fitted curve, but may be another functional form, such as a quadratic curve, a polynomial, etc., and is not specifically limited herein.
In certain embodiments, step 107 comprises:
the second change curve is obtained from the first change curve and a preset relationship between the inter-chamber temperature change rate during the downtime of the compressor 12 and the inter-chamber temperature change rate during the startup time of the compressor 12.
Therefore, the acquisition mode of the control setting curve is simple and feasible, and the efficiency of the control method is improved.
Specifically, the preset relationship may be calibrated and stored in advance, and in one example, the preset relationship may be a unitary linear relationship of the inter-chamber temperature change rate during the shutdown time of the compressor 12 and the inter-chamber temperature change rate during the startup time of the compressor 12, i.e., dtdtdtk=a+b, dtdttg, where a, b are constants, and the specific magnitudes of a, b may be determined according to empirical values.
In one example, the second variation curve obtained is shown in fig. 4 as a control setting curve B. The abscissa represents the indoor temperature IAT, and the ordinate represents the second room temperature change rate dtdtdtk.
It is understood that the preset relationship is not limited to the above-mentioned unitary linear relationship, but may be another functional form, such as a quadratic curve, a polynomial, etc., which is not specifically limited herein.
In certain embodiments, step 109 comprises:
and obtaining an operation curve by using the second room temperature change rate and the room temperature in a fitting mode.
Thus, the operation curve acquisition method is simple and feasible, and the efficiency of the control method is improved.
Specifically, by acquiring the indoor temperature and calculating the second room temperature change rate of the compressor 12 during the on time, the relationship between the second room temperature change rate and the indoor temperature is obtained, by establishing a coordinate system with the abscissa being the indoor temperature IAT and the ordinate being the second room temperature change rate dtdtdttk, the relationship data points of the second room temperature change rate and the indoor temperature can be obtained, and by fitting to a plurality of relationship data points, the operation curve can be obtained. In fig. 5, as an illustration, the fitted operation curve B1 or B2 is a straight line, and as the indoor temperature increases, the second room temperature change rate decreases.
It will be appreciated that in other embodiments, the operating curve is not limited to the form of a fitted curve, but may be another functional form, such as a quadratic curve, a polynomial, etc., and is not specifically limited herein. The first profile and the operating profile may be obtained in the same manner or in different manners.
In certain embodiments, step 111 comprises:
in the case where the deviation is within the set deviation range, the rotation speed of the compressor 12 is controlled to be unchanged;
in the case where the deviation exceeds the set deviation range downward, the rotation speed of the compressor 12 is controlled to be increased so that the deviation is located in the set deviation range;
in the case where the deviation exceeds the set deviation range upward, the rotation speed of the compressor 12 is controlled to be reduced so that the deviation is located within the set deviation range.
In this way, specific control of the rotational speed of the compressor 12 can be achieved.
Specifically, the set deviation range may be calibrated and stored in advance.
In one example, the set deviation range is [ -5%, +5% ] centered on the second room temperature change rate on the control set curve B. At the same room temperature, in the case of the above-mentioned set deviation range, i.e., dtdtdtk 2 x-5% < = dtdtdttk 1< = dtdtdttk 2 x 5%, dtdtdtk 1 represents the second room temperature change rate on the operation curve, dtdtdtk 2 represents the second room temperature change rate on the control setting curve B, it can be considered that the current rotation speed of the compressor 12 can be adapted to the current working condition of the refrigeration appliance 200, and the current rotation speed of the compressor 12 is controlled to be unchanged.
In the case where the second room temperature change rate on the operation curve is downward beyond the above-mentioned set deviation range (as in the operation curve B1 in fig. 5), i.e., dtdtdttk 1< dtdtdttk 2 x-5%, it can be considered that the current rotation speed of the compressor 12 is not suitable for the current operation condition of the refrigerator 200, and the rotation speed of the compressor 12 is controlled to be increased.
In the case where the second room temperature change rate on the operation curve exceeds the above set deviation range (as in the operation curve B2 in fig. 5), that is, dtdttk 1> dtdtdttk 2×5%, the current rotation speed of the compressor 12 may be considered to exceed the rotation speed required for the current working condition of the refrigerator 200, and the rotation speed of the compressor 12 is controlled to be reduced, so that the operation energy consumption of the refrigerator 200 may be reduced.
It is to be understood that in other embodiments, the setting deviation range is not limited to be set to plus or minus 5%, and other setting deviation ranges may be used, and are not particularly limited herein.
