Description

Temperature control method and device, refrigeration equipment and computer readable storage medium
Technical Field
The present invention relates to the technical field of refrigeration equipment, and more particularly, to a temperature control method and apparatus, a refrigeration equipment, and a computer-readable storage medium.
Background
In the current refrigerator, the cold energy of the refrigerating chamber and the temperature-changing chamber is usually provided by the freezing chamber, namely, the low temperature of the freezing chamber is brought to the refrigerating chamber and the temperature-changing chamber through a damper and a fan so as to cool.
However, when the temperature of the refrigerating room or the temperature-variable room is set to 5 ℃ at a low ambient temperature (e.g., the ambient temperature is 5 ℃ or lower), there is no temperature difference between the ambient temperature and the temperature inside the room, and therefore, the amount of heat leaking into the room is very small. At this time, the temperature of the freezing chamber is below 18 ℃ below zero, the blowing flux is the leakage flux of the cooling capacity, and after a period of time, the actual temperature of the temperature-changing chamber or the refrigerating chamber is lower than 0 ℃ due to the influence of the freezing chamber, so that stored articles such as fruits and vegetables can be frozen.
The current conventional treatment solution is to add compensating heating wires in the cold storage room or the temperature change room. When the problems occur, the heating wire is opened for heating, so that the phenomenon caused by cold leakage in the freezing process of the freezing chamber is avoided. However, this way of compensating heating can greatly increase the cost and energy consumption of the refrigerator.

Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
Referring now to fig. 1-2, various exemplary embodiments of the present invention will be described. It is to be understood that the following description is only exemplary of the present invention and is not intended to limit the present invention in any way.
As shown in fig. 1, according to an embodiment of the present invention, a temperature control method of a refrigeration apparatus is provided. Specifically, the temperature control method may include the steps of:
s1: first, the actual temperature of the refrigerating compartment is acquired.
S2: then, in response to the acquired actual temperature satisfying the preset temperature condition, a freezing compartment defrosting state is determined.
S3: and then, in response to the completion of defrosting of the freezing chamber, controlling the residual heat generated in the defrosting process to enter the refrigerating chamber so as to perform heating operation on the refrigerating chamber.
Specifically, according to the embodiments of the present invention described above, when the refrigeration apparatus is used in a low ambient temperature condition (for example, the external ambient temperature is 5 ℃ or less), even if the temperature of the refrigeration compartment is set to, for example, 5 ℃, there is a possibility that the actual temperature of the refrigeration compartment is too low. In view of such a risk, the embodiments of the present invention provide the above temperature control method.
According to the record of the embodiment of the invention, under the condition that the actual temperature of the refrigerating chamber meets the preset temperature condition, the defrosting state of the refrigerating chamber is judged; when the defrosting of the freezing chamber is finished, the waste heat generated by the freezing chamber in the defrosting process is sent to the refrigerating chamber for heating the refrigerating chamber, so that the actual temperature of the refrigerating chamber is compensated and increased, and the risk is prevented. Therefore, compared with the prior art, the embodiment of the present invention does not add other additional elements (such as heating wires) to perform the above-described heating operation, so that the cost is lower and the energy consumption is lower; furthermore, the residual heat of the frost in the freezing chamber is used, so that the energy can be more fully utilized, and the residual heat in the freezing chamber is led out, so that the food storage in the freezing chamber is more facilitated.
It should be understood here that the actual temperature as described above fulfils the preset temperature condition, meaning that for example the actual temperature of the refrigerated compartment is below the set temperature under this condition, leading to a risk of frozen out of stored steamed fruits and the like. That is, according to the embodiment of the present invention, as long as it is detected that the actual temperature of the cooling compartment is lower than the set temperature, the temperature control method provided by the embodiment of the present invention can be appropriately performed so as to compensate for the temperature of the cooling compartment. The above process will be described in more detail by way of example.
It should also be understood that the heater wires of the evaporator generate hot air having a relatively high temperature during defrosting of the freezing chamber, and the generated hot air also affects the temperature of the freezing chamber if not discharged in time. Therefore, the invention effectively monitors the temperature of the refrigerating chamber in the defrosting process of the freezing chamber, and conveys the residual heat from the freezing chamber to the refrigerating chamber or directly conveys the residual heat from the air duct to the refrigerating chamber, so that the temperature compensation can be performed on the refrigerating chamber; on the other hand, it may be more advantageous to store food in the freezing chamber.
In particular, in a conventional refrigerating apparatus, a defrosting operation of a freezing chamber is generally performed by generating heat using a heating wire in an evaporator. After defrosting is finished, the refrigerating equipment continues to refrigerate and consumes the waste heat of the heating wire after defrosting operation is finished through the cold energy generated by refrigeration. In this way, however, on the one hand, the residual heat generated by the heating wires of the evaporator during the defrosting operation is not utilized effectively; on the other hand, the power consumption of the refrigeration apparatus is also increased. In the temperature control method provided by the embodiment of the invention, if the refrigerating chamber needs temperature compensation, after the defrosting of the freezing chamber is finished, the residual heat generated in the defrosting process can be controlled to enter the refrigerating chamber, so that the heating operation is performed on the refrigerating chamber. On one hand, the waste heat in the defrosting process can be fully utilized; on the other hand, since the residual heat in the freezing chamber is guided into the refrigerating compartment, the temperature of the freezing chamber can be reduced back to the set freezing chamber temperature without consuming a large amount of power consumption of the refrigerating apparatus.
Generally, the temperature control method provided by the embodiment of the invention utilizes the residual heat at the end of the defrosting operation, not the heat in the defrosting process. This is because the heat generated during the defrosting process needs to first satisfy the heat requirement of the defrosting operation, and then the residual heat of the defrosting operation is compensated to the refrigerating compartment. In addition, the temperature of the residual heat is higher when defrosting is finished, and the temperature compensation by utilizing the residual heat is more appropriate. In addition, it should be noted that if it is found that temperature compensation is not needed after the actual temperature of the refrigerating compartment is obtained, the residual heat in the defrosting process of the freezing compartment is consumed according to the conventional operation, that is, the refrigerating device continues to refrigerate and consumes the residual heat of the heating wire after the defrosting operation is completed through the cold energy generated by refrigeration.
Generally, in one embodiment, the temperature of the freezer compartment is lower than the temperature of the refrigeration compartment, and the refrigeration from the freezer compartment is ducted into the refrigeration compartment to provide refrigeration to the refrigeration compartment to maintain the proper temperature. According to the embodiment of the invention, when the refrigeration chamber needs to be subjected to temperature compensation, the freezing chamber can stop conveying cold energy to the refrigeration chamber, and the residual heat in the defrosting process is conveyed to the refrigeration chamber through the same pipeline for conveying the cold energy. In other words, the same piping can be used between the freezing chamber and the refrigerating chamber to transport cold or heat as needed, thereby effectively controlling the cost of the refrigerating apparatus without increasing.
Further, according to embodiments of the present invention, the refrigeration apparatus described above and below may be, for example, a refrigerator or freezer; it should be understood that any other refrigeration device having a freezer compartment and a refrigeration compartment and which may suffer from the above-mentioned problems may employ the temperature control method of the embodiments of the present invention. That is, the present invention is not limited to a specific apparatus, and can be performed according to actual needs.
Further, according to an embodiment of the present invention, the refrigerating compartment described above and below may be a refrigerating compartment or a temperature-changing compartment. In other words, it is also understood that a refrigerated compartment as described herein refers to a compartment that is powered by the freezer compartment (including providing cold and heat). Specifically, taking a refrigerator as an example, the refrigerator is generally classified into two types: one is that it includes refrigerating chamber and freezing chamber; the other type comprises a refrigerating chamber, a temperature changing chamber and a freezing chamber. The temperature control method of the embodiment of the invention can be executed between the freezing chamber and the refrigerating chamber, between the freezing chamber and the temperature-changing chamber, and also between the freezing chamber and the refrigerating chamber and the temperature-changing chamber. Therefore, the invention is described only by way of example, with the refrigeration compartment being the temperature-changing compartment; it should be understood that the other cases described above may be performed accordingly without departing from the scope of the invention.
For the above-mentioned case that the actual temperature satisfies the preset temperature condition, in one embodiment, the determining the defrosting status of the freezing compartment in response to the actual temperature satisfying the preset temperature condition may specifically include the following steps:
first, it is determined whether the actual temperature of the refrigerating compartment is equal to or lower than a preset temperature.
And determining the defrosting state of the freezing chamber in response to the fact that the actual temperature is less than or equal to the preset temperature.
That is, in the embodiment described above, when the actual temperature of the refrigerating compartment is equal to or lower than the preset temperature, it may be determined that the actual temperature has satisfied the preset temperature condition, so that the subsequent detection of the defrosting state of the freezing compartment may be performed. According to an embodiment of the present invention, the preset temperature as described above may be set as a difference between the set temperature of the refrigerating compartment and the temperature difference correction value. It should be noted here that the temperature difference correction value may be a parameter value set by a user or a manufacturer in advance, that is, the temperature difference correction value may be set according to specific situations, and thus the embodiment of the present invention is not limited to a certain parameter value or values. In one embodiment, the temperature difference correction value may be selected, for example, in the range of 0 ℃ to 3 ℃; in another embodiment, the temperature difference correction value may be selected, for example, in the range of 0 ℃ to 2 ℃.
Further, in an embodiment of the present invention, the temperature control method may further include the steps of:
and responding to the completion of defrosting of the freezing chamber, and controlling the residual heat generated in the defrosting process of the freezing chamber to enter the refrigerating chamber for a set time.
In practical operation, for example, the duration of the waste heat introduced into the refrigerating chamber may be a preset set time, so that the operation of the present invention is simpler. In yet another embodiment, the set time may be combined with a temperature sensor. Specifically, the set time and an actual temperature sensor for sensing the refrigerating chamber can be combined, and when the temperature sensor senses that the temperature of the refrigerating chamber rises back to the proper temperature, the freezing chamber can be controlled to stop delivering the waste heat to the refrigerating chamber. In this way, the heat compensation operation of the refrigerating compartment can be made more accurate. It should be understood, of course, that the embodiments of the present invention are not limited to the above or any other specific embodiments, and the set time duration may be set according to specific use cases, and the above is only an exemplary embodiment of the present invention. It should also be understood that in embodiments of the present invention, the supply of waste heat from the freezer compartment to the refrigerator compartment may be accomplished in any suitable manner, such as in the embodiment shown in FIG. 2, the waste heat may be supplied to the refrigerator compartment by opening a damper between the freezer compartment and the refrigerator compartment; the manner in which the damper delivers air is merely an illustrative embodiment and the present invention is not so limited.
Referring now to fig. 2, fig. 2 illustrates an exemplary embodiment of the present invention. In this embodiment, a description is given of a variable temperature chamber as a refrigerating compartment.
Specifically, in the embodiment of the present invention, determining whether the actual temperature of the refrigeration compartment is less than or equal to the preset temperature may specifically include:
determining whether the actual temperature of the refrigerating chamber is less than or equal to the difference between the set temperature of the refrigerating chamber and the first temperature difference correction value; or
Determining whether the actual temperature of the refrigerating chamber is less than or equal to the difference between the set temperature of the refrigerating chamber and the second temperature difference correction value,
wherein the first temperature difference correction value is less than the second temperature difference correction value.
Further in an embodiment of the present invention, the temperature control method may further include:
determining the set temperature of the refrigerating chamber;
responding to the set temperature being more than or equal to zero degree, and determining whether the actual temperature of the refrigerating chamber is less than or equal to the difference between the set temperature of the refrigerating chamber and the first temperature difference correction value;
and responding to the set temperature being less than zero degree, and determining whether the actual temperature of the refrigerating chamber is less than or equal to the difference between the set temperature of the refrigerating chamber and the second temperature difference correction value.
In particular, according to an embodiment of the present invention, the purpose of detecting the user-set temperature of the variable temperature chamber (i.e., the cooling compartment) is to determine the current role of the variable temperature chamber. When the set temperature of the temperature-changing chamber is greater than or equal to zero, the temperature-changing chamber is used as a fresh-keeping chamber; when the set temperature of the temperature-variable chamber is less than zero, it is indicated that the temperature-variable chamber is being used as an iced chamber. Generally, if the user of the temperature-changing chamber sets a temperature equal to or higher than zero (i.e., when used as a fresh food compartment), the risk of low temperature as described above is more likely to occur. However, this does not mean that the temperature compensation is not necessary when the temperature-changing chamber is used as a cold chamber. In one embodiment, the set temperature of the variable temperature chamber may be in the range of-18 ℃ to 5 ℃; in another embodiment, the set temperature of the variable temperature chamber may be in the range of-3 ℃ to 5 ℃. It should be understood, however, that the above is only an exemplary embodiment of the set temperature of the variable temperature chamber and does not constitute any particular limitation to the present invention.
Further, according to an embodiment of the present invention, when used as a fresh food compartment, it is determined whether the actual temperature of the variable temperature compartment satisfies the first preset temperature condition in response to the set temperature being equal to or greater than zero degrees. When the variable temperature chamber is used as the icing chamber, whether the actual temperature of the variable temperature chamber meets the second preset temperature condition or not is determined in response to the set temperature being less than zero degree. That is, the embodiment of the present invention can further perform temperature compensation detection and operation in different situations according to the determined actual set usage environment of the temperature-variable chamber (i.e., whether the temperature-variable chamber is used as a fresh-keeping chamber or a freezing chamber). In this way, the temperature control compensation method of the present invention can be implemented more accurately.
In one embodiment, satisfying the first preset temperature condition as described above may be set as: the actual temperature of the refrigerating chamber is less than or equal to the difference between the set temperature TS of the refrigerating chamber and the first temperature difference correction value T1; and satisfying the second preset temperature condition may be set as: the actual temperature of the refrigerating chamber is less than or equal to the difference between the set temperature TS of the refrigerating chamber and the second temperature difference correction value T2. That is, different temperature condition detection is performed for different refrigerating compartment usage. In one embodiment, the first temperature difference correction value T1 may be less than the second temperature difference correction value T2. Similarly to the above, in one embodiment, the first temperature difference correction value and the second temperature difference correction value may be selected, for example, in the range of 0 ℃ to 3 ℃; in another embodiment, the first temperature difference correction value and the second temperature difference correction value may be selected, for example, in a range of 0 ℃ to 2 ℃.
With continued reference to fig. 2, in an embodiment of the present invention, the temperature control method provided in the embodiment of the present invention may further include the following steps:
first, the current ambient temperature is obtained.
Next, in response to the current ambient temperature being less than or equal to the ambient temperature set point, a step of determining a set temperature of the refrigerated compartment is performed.
In this embodiment, the state of the current ambient temperature may be determined first before proceeding with the subsequent operation. That is, if the current ambient temperature is greater than the ambient temperature setting value, it indicates that the refrigeration equipment is not in a low-temperature environment, and therefore, the normal operation state is only required to be maintained.
