Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The refrigeration apparatus, the control method of the refrigeration apparatus, the control system of the refrigeration apparatus, and the computer-readable storage medium according to some embodiments of the present invention are described below with reference to fig. 1 to 7.
The first embodiment is as follows:
taking the refrigeration apparatus shown in fig. 1 as an example, an embodiment of the present invention provides a control method for a refrigeration apparatus, where a specific flow of the control method is shown in fig. 2, and the control method includes:
s202, acquiring a plurality of temperature values in a refrigerating chamber of refrigerating equipment;
in S202, a plurality of temperature values are acquired by a plurality of temperature sensors provided in the cooling compartment, and the number of temperature values corresponds to the number of temperature sensors.
S204, determining an actual temperature value in the refrigerating chamber according to the plurality of temperature values;
and S206, controlling a compressor assembly of the refrigeration equipment according to the actual temperature value.
In some embodiments, as shown in fig. 3, the step of determining an actual temperature value in the cooling compartment according to a plurality of temperature values specifically includes:
s302, acquiring an environmental temperature value of the environment where the refrigeration equipment is located;
s304, determining a weight ratio corresponding to each temperature value in the plurality of temperature values according to the environment temperature value, and calculating an actual temperature value according to the weight ratio and the temperature value.
In S304, under different ambient temperatures, the weight ratios of the temperature values read by the temperature sensors at different positions in the refrigeration compartment are different, and the actual temperature value in the refrigeration compartment is calculated based on the ambient temperature at the position where the refrigeration equipment is located, so that the calculation effect is more accurate, and the refrigeration equipment can obtain a better control effect.
In some embodiments, as shown in fig. 4, the step of controlling the compressor component of the refrigeration equipment according to the actual temperature value specifically includes:
s402, calculating a first difference value between the actual temperature value and the set temperature value based on the fact that the actual temperature value is higher than the set temperature value corresponding to the refrigerating chamber;
s404, determining a target frequency in the initial database according to the first difference value, and controlling the compressor assembly to operate at the target frequency;
and S406, controlling the compressor assembly to stop running based on the absolute value of the first difference value being smaller than the temperature difference threshold value.
By acquiring the temperature values of a plurality of position intervals in the refrigerating chamber of the refrigerating equipment, the problem that the refrigerating equipment is slow in response to temperature change due to the fact that the refrigerating equipment is controlled only through a single temperature value is solved, the response speed in the process of controlling the refrigerating equipment is increased, and the refrigerating efficiency is improved. The actual temperature value in the refrigerating chamber of the refrigerating device is determined according to the temperature values of a plurality of different positions in the refrigerating chamber, and the compressor assembly is controlled to work according to the actual temperature value, so that the temperature in the refrigerating chamber is more uniform, and the refrigerating effect of the refrigerating device is improved.
In fig. 1, the refrigeration device is a side-by-side type refrigerator, and the right side is a refrigerating chamber. A first temperature sensor is arranged at the upper position of the refrigerating chamber and used for acquiring an upper temperature value R1, and a second temperature sensor is arranged at the middle position and used for acquiring a middle temperature value R2. The first temperature sensor and the second temperature sensor are arranged along the height direction of the refrigerating chamber, and the actual temperature value R in the refrigerating chamber is calculated through the following formula:
R＝a×R1+b×R2。
wherein, R is actual temperature value, and R1 is the temperature value that first temperature sensor read, and R2 is the temperature value that second temperature sensor read, and a is first temperature sensor's weight ratio, and b is second temperature sensor's weight ratio, and satisfies:
a+b＝1。
the weight ratios of the temperature values read by the temperature sensors at different positions in the refrigerating room are different, and the actual temperature value in the refrigerating room is calculated based on the environment temperature of the position where the refrigerating equipment is located, so that the calculation effect is more accurate, and the refrigerating equipment can obtain a better control effect.
Specifically, in a practical use scenario, cold air may be gathered at the lower portion of the refrigeration compartment, the temperature rise rate of the upper portion of the refrigeration compartment may be relatively fast, and the temperature difference between the upper portion and the lower portion of the refrigeration compartment may change along with the change of the ambient temperature. Therefore, corresponding weight ratios are set for temperature values obtained by different sensors, and compared with the method of directly calculating the average value of a plurality of temperatures, the finally obtained actual temperature value is more in line with the actual control requirement, and the better refrigeration control effect is favorably obtained.
When the actual temperature in the refrigerating chamber is higher than the set temperature value, the further refrigerating requirement is indicated. At the moment, the corresponding target frequency is searched according to the first difference value of the actual temperature and the set temperature, the compressor assembly of the refrigeration equipment is controlled to run through the target frequency, the compressor is prevented from running frequently at full speed, the running noise and the running energy consumption are reduced on the premise that the refrigeration effect of the refrigeration equipment is ensured, and the running effect of the refrigeration equipment is improved.
In some embodiments, the compressor frequency correspondence file for different cooling capacity requirements is preset in the refrigeration equipment. The refrigerating capacity requirement is determined by the actual temperature in the refrigerating chamber and the set temperature of the refrigerating chamber.
For the stepless frequency conversion compressor, the running frequency of the compressor can be completely and dynamically adjusted through the preset compressor frequency curve.
For a common variable frequency compressor, the operating frequency of the compressor can be divided into a plurality of different gears, and each gear corresponds to different refrigerating capacity requirements.
For a fixed frequency compressor, different refrigeration capacity requirements correspond to different compressor run times.
Example two:
as shown in fig. 5, the control method of the refrigeration apparatus according to the embodiment of the present invention further includes, after the step of controlling the compressor assembly to operate at the target frequency:
s502, determining a first change rate of the temperature value according to the temperature value, and acquiring an initial temperature change rate;
s504, determining a second difference value between the first change rate and the initial temperature change rate according to the set frequency until the compressor assembly stops running;
in S504, the initial temperature change rate represents an estimated temperature change curve in the refrigerating compartment under the influence of the refrigerating capacity of the compressor assembly under a preset ideal condition. And a second difference between the first rate of change and the initial rate of temperature change may represent a difference between the actual rate of temperature change and the estimated temperature change profile.
S506, recording a first environment temperature value, a first change rate and a target frequency based on the fact that the difference between the maximum value of the second difference and the minimum value of the second difference is smaller than a difference threshold value.
In S506, the difference between the maximum value of the second difference and the minimum value of the second difference may represent the fluctuation condition of the actual temperature variation curve, and if the fluctuation range is small, it indicates that the current refrigeration compartment is less affected by other external environments, and the refrigeration environment is more suitable for the general application environment. At this time, a first ambient temperature value, a first change rate and a target frequency in the current cooling process can be recorded.
If the fluctuation condition is large, if the fluctuation is larger than 20% (namely the difference between the maximum value of the second difference value and the minimum value of the second difference value is larger than 20% of the average value of the second difference value), it indicates that special conditions may occur in the current scene, for example, the refrigeration compartment door is not closed tightly, and a user puts a large amount of articles with large specific heat capacity, such as "mineral water" and the like, at one time, and the working parameters of the current refrigeration process do not have general representativeness, so that the working parameters of the current refrigeration process are not recorded.
In some embodiments, as shown in fig. 6, after the step of controlling the compressor assembly to stop operating, the control method of the refrigeration apparatus further includes:
s602, determining a second change rate of the temperature value according to the temperature value;
s604, determining a third difference value between the second change rate of the temperature value and the initial temperature change rate according to the set frequency until the compressor component starts to operate;
s606, recording a second environment temperature value, a second temperature value and a second change rate based on the difference between the maximum value of the third difference value and the minimum value of the third difference value being smaller than the difference threshold value.
In some embodiments, the control method of the refrigeration appliance further comprises: and establishing an actual database according to the first environment temperature value, the first change rate, the target frequency, the second environment temperature value, the second temperature value and the second change rate so as to enable the refrigeration equipment to operate according to the actual database.
In some embodiments, the refrigeration apparatus includes a refrigeration compartment, a plurality of temperature sensors are disposed in the refrigeration compartment, the temperature sensors are distributed along a height direction of the refrigeration compartment, and are configured to acquire temperature values, and the control method of the refrigeration apparatus further includes: the method comprises the steps of obtaining the running state of a sensor, and replacing a first actual database corresponding to the sensor in the fault state with a second actual database corresponding to the sensor in the non-fault state based on the fact that any sensor is in the fault state.
Wherein, the record is at the first rate of change of the temperature value that each sensor recorded in refrigeration process, refrigeration plant the first ambient temperature of environment, the target frequency (the operation gear) of the compressor that this time refrigeration process corresponds to and after reaching the refrigeration effect, the temperature value that acquires when the compressor shut down, establish user's own operation database according to actual working parameter and the work effect that record to do benefit to refrigeration plant and work according to the working parameter that accords with user actual conditions in work afterwards, make refrigeration plant's work effect laminate user's actual demand more, improve refrigeration plant's work effect.
For example, a first temperature sensor and a second temperature sensor are arranged in the refrigeration compartment, after the compressor assembly starts to operate, a temperature value R1 is obtained by the first temperature sensor every 2min interval, a temperature value R2 is obtained by the second temperature sensor every 2min interval, and the change speed (cooling speed) Δ T1 of the temperature value R1 and the change speed (cooling speed) Δ T2 of the temperature value R2 are determined.

After refrigeration equipment stops refrigerating, the record is under the condition that compressor unit spare is closed, the indoor second temperature rate of change of refrigeration room to and present second ambient temperature, establish the environmental database of this refrigeration equipment mounted position according to the actual temperature situation of change that records, in order to do benefit to refrigeration equipment in the work afterwards according to the actual environment characteristics work that accords with the position, prevent to be not conform to actual environment according to predetermineeing the control of database to refrigeration equipment, improve refrigeration equipment's work efficiency.
For example, a first temperature sensor and a second temperature sensor are provided in the refrigeration compartment, and after the compressor assembly is shut down, the change speeds (heating speeds) Δ T11 and Δ T21 of the temperature value R1 acquired by the first temperature sensor and the temperature value R2 acquired by the second temperature sensor are determined.
Calculating difference values of delta T11 and delta T21 and a preset initial temperature change rate respectively, and if the fluctuation of the difference values is less than or equal to 20%, recording starting points of R1 and R2 (namely real-time temperatures respectively acquired by a first temperature sensor and a second temperature sensor when the compressor assembly is started) Trk1 and Trk2, heating speeds delta T11 and delta T21, an ambient temperature Trs2 and a set gear (namely target frequency of the compressor) when the compressor assembly is started again.
According to the working parameter and the environmental parameter that record and generate actual database, this actual database and user's use custom and refrigeration plant's installation environment phase-match, through actual database control refrigeration plant work, can make refrigeration plant's the actual demand of user of fitting more, improve refrigeration plant's working effect, prevent simultaneously according to predetermineeing that the database is not conform to actual environment to refrigeration plant's control, improve refrigeration plant's work efficiency.
According to the working parameter and the environmental parameter that record and generate actual database, this actual database and user's use custom and refrigeration plant's installation environment phase-match, through actual database control refrigeration plant work, can make refrigeration plant's the actual demand of user of fitting more, improve refrigeration plant's working effect, prevent simultaneously according to predetermineeing that the database is not conform to actual environment to refrigeration plant's control, improve refrigeration plant's work efficiency.
When the actual databases are established, the corresponding actual databases are respectively set for each sensor, when any sensor fails and cannot work normally, the second actual databases corresponding to other sensors can be called to perform virtual sensor control, the phenomenon that the whole refrigeration equipment cannot run due to sensor failure is avoided, and the running reliability of the refrigeration equipment is improved.
