Fig. 3 is a flow chart of another temperature control method according to an embodiment of the present application. Fig. 3 is presented on the basis of the first embodiment. According to the diagram provided in fig. 3, the temperature control method specifically further includes:

and S301, when a door opening signal is detected and the target equipment meets a preset first condition, starting a temperature regulation mode, and controlling the compressor to execute a first starting operation.

And S303, controlling the compressor to operate the second starting operation when the target object is stored in the target equipment and the target temperature of the target equipment exceeds the high target temperature threshold.

The high target temperature threshold referred to herein may be understood as a start-up condition temperature for the compressor of the refrigeration appliance. For example, the high target temperature threshold is set to-77 DEG, and when the internal temperature of the refrigeration equipment is higher than-77 DEG, the high target temperature threshold is set as the start-up condition temperature of the compressor.

Further, after the door opening signal exists in the refrigeration equipment, the door opening control mode is started. When the internal temperature of the refrigeration equipment is detected to exceed the set high target temperature threshold, the internal temperature of the current refrigeration equipment is high, quick refrigeration needs to be started, and at the moment, a reference is provided for the next quick refrigeration by starting the restarting operation of the compressor.

The target adjustment times are understood to be a cycle determination process through a plurality of start-up and shut-down of the compressor in the refrigeration appliance. The quotient here is understood to mean a multiple of the adjustment frequency value of the temperature difference.

Further, when the cooling equipment starts the sectional frequency-raising operation, firstly, according to the surface temperature of a newly placed target object, comparing the surface temperature with the set maximum rated temperature of the inside of the cooling equipment, obtaining a temperature difference as a reference quantity for calculating sectional adjustment. Setting an adjustment frequency value as the minimum amount of adjustment times, dividing the obtained total temperature difference by the adjustment frequency value, and obtaining a quotient value as the basis of the number of times of starting and stopping the compressor, thereby obtaining the number of times of starting and stopping the compressor in the temperature adjustment mode.

In one possible example, assuming that an apple placed in the refrigerator at a certain moment is detected by a detection device in the refrigerator, since the surface temperature of the apple is higher than the refrigerating temperature of the refrigerator, 20 ° is obtained by acquiring the surface temperature of the apple, the temperature in the refrigerating chamber of the refrigerator is set to 5 °, and the temperature difference is obtained by calculation. In order to calculate the sectional frequency-up regulation times of the refrigerator compressor, the regulation frequency value is set to be 5, and the 15 degrees/5=3 is utilized, so that the compressor is determined to need three on-off circulation treatment processes.

For another example, for the low-temperature refrigerating chamber, the set temperature is-80 degrees, fresh meat is put in after a user opens the door, the surface temperature of the meat is detected to be 10 degrees through the temperature, the temperature difference is calculated to be 10- (-80) 90), the adjustment frequency value is set to be 10, and the adjustment times are calculated through division: 90/10=9, the purpose of rapid cooling is gradually realized through the 9 times of start-stop processes of the compressor, and in the readjustment process, the stop temperature value corresponding to each start-stop process is smaller than the temperature threshold value set last time, so that the purpose of saving energy is achieved. For example, the starting temperature threshold value corresponding to the starting and stopping of the first compressor is-77 degrees, the stopping temperature threshold value is-83 degrees, the second starting temperature threshold value is-78 degrees, the stopping temperature threshold value is-82 degrees, and the like, so that the purpose of saving energy is achieved while rapid cooling is achieved.

The second target frequency is understood here to be the operating frequency of the second up-conversion temperature regulation process corresponding to the compressor of the refrigeration appliance.

Further, by utilizing a sectional frequency-raising mode of the compressor, when the target adjustment times are not finished, the working frequency of the compressor corresponding to the current adjustment process is lower than the working frequency in the last starting and stopping process, and meanwhile, the starting temperature threshold value and the stopping temperature threshold value in the current starting and stopping process are set to be larger than the starting temperature threshold value and the stopping temperature threshold value in the last starting and stopping process of the compressor, so that the reduction of the operating frequency and the reduction of the total refrigerating capacity of the refrigerating equipment are realized.

S310, judging whether the target temperature is smaller than a second low temperature threshold value, and determining a judging result, wherein the second low temperature threshold value is smaller than the low target temperature threshold value.

And S311, determining a third result when the target temperature is smaller than the second low temperature threshold value.

Further, during a start-up and shut-down of the compressor of the refrigeration equipment, the second low temperature threshold is set to be lower than the shut-down temperature threshold of the compressor during normal operation of the refrigeration equipment. For example, the shutdown temperature threshold value of the corresponding compressor is set to-80 degrees in the normal operation start-stop process of the refrigeration equipment, the shutdown temperature threshold value of the compressor is set to-83 degrees when the refrigeration equipment is in the first start-stop cycle process, and when the temperature inside the refrigeration equipment is detected to be lower than-83 degrees, the shutdown operation of the compressor is executed. Setting a second shutdown temperature threshold to-82 degrees when the compressor enters the next startup and shutdown process (setting the shutdown temperature threshold to be smaller than the shutdown temperature threshold when the refrigeration equipment does not have a door or has articles put in, and setting the current shutdown temperature threshold to be larger than the shutdown temperature threshold in the last startup and shutdown process at the same time, for example, -83 DEG < 82 DEG < 80 DEG), executing the shutdown operation of the compressor when the internal temperature of the refrigeration equipment is lower than-82 DEG, subtracting one operation from the target regulation times, and judging whether the target regulation times is zero again as the ending condition of the stop temperature regulation mode.

And S317, when the target adjustment times are not zero, executing the step of determining the corresponding temperature control strategy based on the target adjustment times.

Further, the starting and stopping processes of temperature regulation are carried out for a plurality of times through the compressor of the refrigeration equipment, and after the current starting and stopping cycle is finished each time, the next starting and stopping frequency raising and cooling process of the compressor is carried out at a set period time interval.

And S318, controlling the compressor to keep running based on the second temperature control strategy, and executing the step of judging whether the target temperature is smaller than a second low temperature threshold value.

Further, after the start-up operation of the compressor is started, periodically detecting whether the internal temperature of the current refrigeration equipment reaches the shutdown temperature of the compressor, if the internal temperature of the refrigeration equipment does not reach the shutdown temperature of the compressor, continuing to maintain the rapid refrigeration mode of the compressor until the internal temperature of the refrigeration equipment reaches the shutdown temperature of the compressor, and stopping running.

And S319, when the second target frequency of the compressor is equal to the target frequency, the temperature regulation mode is turned off.

S320, when the second low temperature threshold value of the compressor is equal to the low target temperature threshold value, the temperature regulation mode is turned off.

Further, the refrigerating equipment realizes a rapid cooling process according to the sectional frequency rising, when the compressor is in a certain start-stop process, and the corresponding start-up temperature threshold value and stop temperature threshold value are not in a door opening signal or a target object is placed in the refrigerating equipment, the temperature regulation mode of the characterization refrigerating equipment reaches a stop condition, and the refrigerating equipment is controlled to return to a normal working mode by closing the temperature regulation mode, so that the aim of reducing the total refrigerating capacity of the refrigerating equipment for achieving rapid refrigeration is fulfilled.

In a possible example scenario, fig. 4 is a schematic flow chart of still another temperature control method according to an embodiment of the present application. The refrigerating equipment is electrified, the compressor runs at full frequency, after the temperature is quickly pulled, the refrigerating system steps into stable operation, namely, a start-stop stage, and the temperature Td of the refrigerating equipment is smaller than the set temperature Ts of the equipment. After the compressor stops running, the temperature of the refrigeration equipment is raised back to some extent due to heat leakage, and when the temperature is raised back to a certain value DeltaT 20 higher than the set temperature, namely Td is more than Ts+ DeltaT20, the compressor is restarted, and the temperature is raised to a target frequency F00 (the working frequency when the compressor does not have a door opening signal) and kept running. When the temperature is reduced to be lower than the set temperature by a certain value delta T10, namely Td < Ts-delta T10, the compressor is stopped, and when the temperature rise does not meet the refrigeration requirement, the compressor is restarted again.

When the refrigerating equipment detects a door opening signal, a refrigerating program of the refrigerating system enters a door opening control mode, when the door opening duration of the refrigerating equipment reaches a set time T, preferably t=3min, or a door closing signal is received in a short time, the compressor is quickly increased to F01 (the set F01 is larger than F00), the refrigerating capacity is far larger than the heat leakage capacity, the temperature of the refrigerating equipment is quickly reduced until the temperature of the refrigerating equipment is lower than a set temperature by a certain value DeltaT 11, namely Td < Ts-DeltaT 11, and the compressor is stopped.

At this time, whether a new sample is stored in the device is detected, when the new sample is stored in the refrigerating device, a warehouse-in list is artificially added in the display screen, and when the warehouse-in list shows that materials are increased, only the period of the rapid temperature pulling is carried out, the surface temperature of the sample can be rapidly reduced, and the internal temperature of the sample is still higher. In order to make the temperatures of the samples consistent as soon as possible, the refrigerating device needs to undergo a plurality of rapid temperature pulling processes, but the aim of energy saving is also considered, and the refrigerating capacity in each rapid temperature pulling Wen Zhouqi is reduced compared with the previous period until the target refrigerating capacity at the set temperature is reached.

When a new sample is detected to be stored in the refrigerating equipment, after the refrigerating equipment is subjected to the first rapid temperature pulling, the temperature is raised to be higher than a set temperature by a certain value DeltaT 21, namely Td > Ts+ DeltaT21, the compressor is started, and the temperature is rapidly raised to F02 (the F02 is set to be smaller than F01) until the temperature of the refrigerating equipment is lower than the temperature of the refrigerating equipment by a certain value DeltaT 12, namely Td < Ts-DeltaT12, and the compressor is stopped.

When the temperature rises to be higher than the set temperature by a certain value DeltaT 22, namely Td is more than Ts+DeltaT 22, the compressor is started, and the temperature is quickly increased to F03 (the set F03 is smaller than F02), until the temperature of the refrigeration equipment is lower than the temperature of the refrigeration equipment by a certain value DeltaT 13, namely Td < Ts-DeltaT 13, and the compressor is stopped.

Only two periods are set, and after two rapid temperature pulls, the door opening control mode is exited. A plurality of cycles may be set as needed, wherein F01 > F02 > F03 > F00, deltaT 11 >. DELTA.T12 >. DELTA.T13 >. DELTA.T10, deltaT21 < [ DELTA ] T22< [ DELTA ] T20.

When the door opening and closing action is detected, but only the sample is taken, and no new sample is stored, the refrigerating equipment can meet the sample storage requirement through the first quick temperature pulling, and at the moment, the refrigerating system exits from the door opening control program.

After exiting the door opening control mode, the refrigerating system operates according to a target mode, specifically, when the temperature of the equipment to be refrigerated is raised to be higher than a set temperature by a certain value DeltaT 20, namely Td is more than Ts+DeltaT20, the compressor is started, the frequency is raised to a target frequency F00 until the temperature of the equipment to be refrigerated is lowered to be lower than the set temperature by a certain value DeltaT 10, namely Td is less than Ts-DeltaT 10, and the compressor is stopped.

Satisfying F01 > F02 > F03 > F00, deltaT 11 > -DeltaT 12 > -DeltaT 13 > -DeltaT 10, deltaT 21< DeltaT22 < DeltaT20. Finally, the purpose of rapid cooling is achieved.
