The refrigerating and freezingapparatus 10 may further include an air outlet damper for opening and closing theair outlet 111 of thedeep cooling compartment 110 and a return air damper for opening and closing thereturn air inlet 112 of thedeep cooling compartment 110.

The present embodiment also provides a control method of the cold storage and freezingapparatus 10, which can be executed by the controller 300 in the cold storage and freezingapparatus 10 of the above-described embodiment, and fig. 3 is a schematic diagram of the control method of the cold storage and freezingapparatus 10 according to an embodiment of the present invention. A method of controlling arefrigeration chiller 10 according to one embodiment of the present invention may generally include:

s302, an instruction acquisition step: a command to enter the fast cryogenic mode forcryogenic compartment 110 is obtained. In some embodiments, the refrigerator-freezer 10 may obtain an instruction from a user to enter the fast-deep-cooling mode, for example, a manipulation interface or a button or the like may be provided on thebox 100 of the refrigerator-freezer 10 to facilitate the user to issue the instruction to enter the fast-deep-cooling mode. In other embodiments, the refrigeration andfreezing apparatus 10 may obtain the instruction to enter the fast deep cooling mode according to the temperature in thedeep cooling compartment 110, for example, when the temperature in thedeep cooling compartment 110 reaches a preset temperature value, the preset temperature value may be selected according to experimental conditions.

S304, a first response step: the refrigeration system 200 is controlled to operate in a first state for a first time threshold. The first state may be that only thefirst compressor 210 and the second compressor 220 of the refrigeration system 200 are activated, and the first time threshold may be 30 minutes to 60 minutes, for example, 30 minutes, 40 minutes, 50 minutes, 60 minutes, etc., to provide sufficient cooling to thecryogenic compartment 110.

S306, a first judgment step: it is determined whether the temperature ofcryogenic compartment 110 satisfies a first predetermined condition. Step S308 is executed if the temperature of thecryogenic compartment 110 satisfies the first preset condition, and the process returns to step S304 if the temperature of thecryogenic compartment 110 does not satisfy the first preset condition.

The top temperature and the bottom temperature of thedeep cooling compartment 110 may also be obtained between step S302 and step S304, and the larger one of the top temperature and the bottom temperature is selected as the first temperature value. The top temperature and the bottom temperature obtained at this time are generally 25 to-20 degrees celsius, that is, the first temperature value is generally 25 to-20 degrees celsius.

And the steps S304 and S306 may further include: and acquiring the air outlet temperature and the return air inlet temperature of thedeep cooling chamber 110, and selecting the larger one of the air outlet temperature and the return air inlet temperature as a second temperature value. The air outlet temperature and the return air inlet temperature obtained at this time are generally between-18 ℃ and-23 ℃, that is, the second temperature value is generally between-18 ℃ and-23 ℃.

And the first preset condition is that the first temperature value is smaller than the second temperature value. The temperature of each region indeep cooling compartment 110 is comprehensively considered, so that the accuracy of judgment in step S306 is improved.

S308, a second response step: controlling the refrigeration system 200 to operate in the second state. Wherein the cooling capacity of the refrigeration system 200 is greater when operating in the first state than when operating in the second state. The second state is that only thefirst compressor 210 and thesemiconductor device 230 are activated or only the second compressor 220 and thesemiconductor device 230 are activated in the refrigeration system 200.

This manner of adjusting the operation state of the refrigeration system 200 according to the temperature of thecryogenic compartment 110 may improve the freshness-keeping effect of thecryogenic compartment 110. Also, since step S306 follows step S304, and step S304 causes the refrigeration system 200 to operate in the first state for the first time threshold. That is, the operating state of the refrigeration system 200 is unchanged during the first time threshold. Therefore, the operation state of the refrigeration system 200 does not need to be adjusted in real time, so that the service life of the refrigeration system 200 is long, and the user experience is improved.

Step S308 may be followed by determining whether the refrigeration system 200 is operating in the second state for a second time threshold and the temperature of thecryogenic compartment 110 meets a second predetermined condition. The second time threshold may be 20 minutes to 30 minutes, such as 20 minutes, 22 minutes, 25 minutes, 28 minutes, 30 minutes, and so forth. That is, the first time threshold is greater than the second time threshold, because the cooling capacity when the refrigeration system 200 is operating in the first state is greater than the cooling capacity when operating in the second state, and therefore the temperature of thecryogenic compartment 110 is susceptible to fluctuation when the refrigeration system 200 is operating in the second state, which may ensure that the temperature within thecryogenic compartment 110 is stable.

In the case where the refrigeration system 200 is operated in the second state for a second time threshold and the temperature of thecryogenic compartment 110 satisfies the second preset condition, the refrigeration system 200 is controlled to operate in the third state for a third time threshold. Wherein the cooling capacity of the refrigeration system 200 in the second state is greater than the cooling capacity in the third state. The third state may be that only thesemiconductor device 230 in the refrigeration system 200 is activated. Because the temperature of thedeep cooling chamber 110 is lower, the arrangement mode not only can save energy, but also can ensure the temperature stability of thedeep cooling chamber 110.

The third time threshold may be 10 minutes to 20 minutes, such as 10 minutes, 12 minutes, 15 minutes, 18 minutes, 20 minutes, and so forth. That is, the second time threshold is greater than the third time threshold, because the cooling capacity when the refrigeration system 200 is operating in the second state is greater than the cooling capacity when operating in the third state, and therefore the temperature of thecryogenic compartment 110 is more likely to fluctuate when the refrigeration system 200 is operating in the third state, which can ensure a stable temperature within thecryogenic compartment 110.

In some embodiments, the refrigeration system 200 may be controlled to operate in the third state for the third time threshold while the air outlet damper and the air return damper are closed to prevent the cold of thecryogenic compartment 110 from leaking out, so that the temperature of thecryogenic compartment 110 is raised.

The top temperature, the bottom temperature, the air outlet temperature and the air return opening temperature of thedeep cooling compartment 110 may be obtained again between the step S308 and the step of judging whether the refrigeration system 200 operates in the second state for the second time threshold and whether the temperature of thedeep cooling compartment 110 meets the second preset condition, a larger one of the obtained top temperature and the obtained bottom temperature is selected as a third temperature value, and a larger one of the obtained air outlet temperature and the obtained air return opening temperature is selected as a fourth temperature value. The top temperature and the bottom temperature obtained at this time are generally in the range of-20 degrees celsius to-40 degrees celsius, that is, the first temperature value is generally in the range of-20 degrees celsius to-40 degrees celsius. The air outlet temperature and the return air inlet temperature obtained at this time are generally between-38 ℃ and-42 ℃, that is, the second temperature value is generally between-38 ℃ and-42 ℃.

And the second preset condition is that the third temperature value is less than the fourth temperature value. The temperature of each area in thedeep cooling chamber 110 is comprehensively considered, so that the judgment accuracy is improved.

After controlling the refrigeration system 200 to operate in the third state for the third time threshold, it may be further determined whether the temperature of thecryogenic compartment 110 satisfies a third predetermined condition. If so, the refrigeration system 200 is controlled to stop refrigerating to save energy.

The step of controlling the refrigeration system 200 to operate in the third state for the third time threshold and the step of determining whether the temperature of thedeep cooling compartment 110 meets the third preset condition may further acquire the top temperature, the bottom temperature, the air outlet temperature, and the return air inlet temperature of thedeep cooling compartment 110 again, select the larger one of the top temperature and the bottom temperature acquired again as the fifth temperature value, and select the larger one of the air outlet temperature and the return air inlet temperature acquired again as the sixth temperature value. The top and bottom temperatures obtained at this time are typically between-40 degrees celsius and-50 degrees celsius, i.e., the first temperature value is typically between-40 degrees celsius and-50 degrees celsius. The air outlet temperature and the return air inlet temperature obtained at this time are generally between-48 ℃ and-55 ℃, that is, the second temperature value is generally between-48 ℃ and-55 ℃.

And the third preset condition is that the fifth temperature value is smaller than the sixth temperature value. The temperature of each area in thedeep cooling chamber 110 is comprehensively considered, so that the judgment accuracy is improved.
