[0001] This application relates to the field of refrigeration technology, specifically to a refrigerator, a temperature compensation system, a freezing capacity testing method, a freezing control method, and a medium. Background Technology

[0002] Refrigerators are common household appliances used for preserving, refrigerating, or freezing food, medicine, etc. Single-system refrigerators are a common type, using a single compressor to supply cooling to both the refrigerator and freezer compartments. The freezer temperature can only decrease or increase in response to changes in the refrigerator temperature. Because the refrigerator temperature easily reaches the preset range, the compressor operates less frequently, making it difficult for the freezer to meet cooling requirements. Summary of the Invention

[0003] This application provides a refrigerator, a temperature compensation system, a freezing capacity testing method, a freezing control method, and a medium, aiming to solve the technical problem in the prior art where the compressor's operating rate is low due to the limited cooling capacity required by the refrigerator compartment, thus failing to meet the temperature requirements of the freezer compartment.

[0004] In a first aspect, this application proposes a temperature compensation system for a refrigerator, the refrigerator further comprising a compressor, a refrigerator compartment, and a freezer compartment; the compressor is configured to provide cooling capacity to the refrigerator compartment and the freezer compartment; comprising:

[0005] A compensating heater is used to provide heat compensation to the temperature of the refrigerator compartment;

[0006] A first compensation circuit is connected to the compensation heater.

[0007] A second compensation circuit is connected in parallel with the first compensation circuit and is connected to the compensation heater;

[0008] A first switch, configured to select either the first compensation circuit or the second compensation circuit to be activated based on ambient temperature; and

[0009] The second switch is disposed on the second compensation circuit and is configured to open or close according to the temperature of the refrigerator compartment.

[0010] When the ambient temperature is lower than the first preset temperature, the first switch selects the first compensation circuit to be turned on, so that the compensation heater provides heat compensation to the refrigerator compartment.

[0011] When the ambient temperature is higher than the first preset temperature, the first switch selects the second compensation circuit to be turned on; and when the temperature of the refrigerator compartment is lower than the second preset temperature, the second switch is closed so that the compensation heater provides heat compensation to the refrigerator compartment.

[0012] Optionally, the temperature compensation system further includes a first temperature sensor and a second temperature sensor; the first temperature sensor is configured to collect the ambient temperature; and the second temperature sensor is configured to collect the temperature of the cold storage compartment.

[0013] Optionally, the first switch is a first temperature control switch; the first temperature control switch includes the first temperature sensor and a first switching element; the first switching element is configured to select either the first compensation circuit or the second compensation circuit to be turned on according to the ambient temperature; and / or

[0014] The second switch is a second temperature control switch, which includes the two temperature sensors and the second switching element; the second switching element is configured to open or close according to the temperature of the refrigerator compartment.

[0015] Optionally, the first preset temperature ranges from 8 to 10°C; the second preset temperature ranges from 0°C to 0.5°C; and / or

[0016] When the temperature of the refrigerator compartment is higher than the third preset temperature, the second switch is turned off so that the compensation heater stops providing heat compensation to the refrigerator compartment; the value of the third preset temperature is in the range of 3.5-4.5℃.

[0017] Optionally, the temperature compensation system further includes a power supply configured to provide electrical energy to the compensation heater via the first compensation circuit or the second compensation circuit.

[0018] Secondly, this application also proposes a method for testing the freezing capacity using the temperature compensation system described above, the freezing capacity testing method comprising:

[0019] The compressor is controlled to start at a preset operating rate, and the temperature inside the freezer compartment and / or the rate of temperature decrease of the freezer compartment are obtained; the lowest temperature inside the freezer compartment and / or the rate of temperature decrease of the freezer compartment are the freezing capacity evaluation indicators at the preset operating rate.

[0020] Obtain the ambient temperature;

[0021] When the ambient temperature is lower than the first preset temperature, the first switch is controlled to select the first compensation circuit to be turned on, so that the compensation heater provides heat compensation to the refrigerator compartment;

[0022] When the ambient temperature is higher than the first preset temperature, the first switch is controlled to select the second compensation circuit to be turned on, and the temperature of the refrigerator compartment is obtained.

[0023] When the temperature of the refrigerator compartment is lower than the second preset temperature, the second switch is controlled to close so that the compensation heater provides heat compensation to the refrigerator compartment.

[0024] Thirdly, this application also proposes a freezing control method employing the temperature compensation system described above, the freezing control method comprising:

[0025] Obtain the required temperature for the freezer compartment;

[0026] The compressor's operating rate is determined based on the required temperature.

[0027] Control the compressor to operate at the stated start-up rate;

[0028] Obtain the ambient temperature;

[0029] When the ambient temperature is lower than the first preset temperature, the first switch is controlled to select the first compensation circuit to be turned on, so that the compensation heater provides heat compensation to the refrigerator compartment;

[0030] When the ambient temperature is higher than the first preset temperature, the first switch is controlled to select the second compensation circuit to be turned on, and the temperature of the refrigerator compartment is obtained.

[0031] When the temperature of the refrigerator compartment is lower than the second preset temperature, the second switch is controlled to close so that the compensation heater provides heat compensation to the refrigerator compartment.

[0032] Fourthly, this application also proposes a storage medium storing a computer program that is loaded by a processor to execute the steps in the freezing capacity testing method or the freezing control method as described above.

[0033] Fifthly, this application also proposes a refrigerator including the temperature compensation system as described above.

[0034] Optionally, the refrigerator further includes a freezer evaporator and a refrigerator evaporator; the compressor is connected to the freezer evaporator and the refrigerator evaporator; the freezer evaporator is configured to provide cooling capacity to the freezer compartment, and the refrigerator evaporator is configured to provide cooling capacity to the refrigerator compartment.

[0035] Because the compressor operates at a very low rate when the ambient temperature is lower than the first preset temperature, it is difficult to meet the freezing requirements. Therefore, the first switch selects the first compensation circuit to be turned on, so that the compensation heater provides heat compensation to the refrigerator compartment, thereby prompting the compressor to increase its operating rate. This allows the refrigerator to obtain more cooling capacity in the freezer compartment at low ambient temperatures, thus improving the freezing capacity of the freezer compartment.

[0036] When the ambient temperature is higher than the first preset temperature, the compressor's operating rate increases. However, when the refrigerator compartment temperature is lower than the second preset temperature, the compressor will stop operating once it reaches the set temperature. This will also cause the freezer compartment temperature to fail to meet the cooling requirements or the time required for the freezer compartment to reach the required temperature to be met. Therefore, in the technical solution of this application, when the ambient temperature is higher than the first preset temperature, based on the increased compressor operating rate, the first switch selects the second compensation circuit to be activated. At this time, the opening or closing of the second switch is controlled according to the refrigerator compartment temperature. When the refrigerator compartment temperature is lower than the second preset temperature, the second switch closes, so that the compensation heater provides heat compensation to the refrigerator compartment, thereby increasing the refrigerator compartment temperature and increasing the compressor's operating rate. This ensures that the freezer compartment temperature reaches the cooling requirements or the time required for the freezer compartment to reach the required temperature is met.

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details.

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0046] Refrigerators are common household appliances used for preserving, refrigerating, or freezing food, medicine, etc. Single-system refrigerators are a common type, using a single compressor to provide cooling to both the refrigerator and freezer compartments. Because the refrigerator compartment temperature easily reaches the preset range, the compressor operates less frequently, making it more difficult for the freezer compartment to meet cooling requirements.

[0047] In some technologies, in low-temperature environments, a compensating heater is used to provide thermal compensation to the refrigerator compartment to increase the compressor's operating rate, thereby improving the refrigeration requirements of the freezer compartment in low-temperature environments. However, in some cases, such as when testing the refrigeration capacity of the freezer compartment, the temperature of the freezer compartment needs to drop rapidly from a relatively high temperature (close to or above room temperature) to below -18°C. However, when the compressor is turned on, the temperatures of both the freezer and refrigerator compartments drop simultaneously. However, the refrigeration capacity required by the refrigerator compartment is limited, resulting in a low compressor operating rate. Consequently, the temperature of the freezer compartment cannot meet the requirement of rapidly dropping from a relatively high temperature (close to or above room temperature) to below -18°C, or it cannot drop to -18°C at all.

[0048] Therefore, the technical solution of this application provides a temperature compensation system that can simultaneously control the start and stop of the compensation heater in the refrigerator compartment according to the external ambient temperature and the internal temperature of the refrigerator compartment, thereby increasing the compressor's operating rate to meet the requirements of the refrigeration capacity test or the refrigeration demand.

[0049] Single-system refrigerators are a common type of refrigerator, using a single compressor to provide cooling to both the refrigerator and freezer compartments. The refrigeration system of a single-system refrigerator includes: a compressor, a condenser, a throttling device, a freezer evaporator, and a refrigerator evaporator. The compressor is connected to both the freezer and refrigerator evaporators; the freezer evaporator is configured to provide cooling to the freezer compartment, and the refrigerator evaporator is configured to provide cooling to the refrigerator compartment. The compressor compresses the refrigerant; the compressed refrigerant enters the condenser to release heat, and then is throttled and depressurized through the throttling device to become a low-temperature, low-pressure refrigerant; the low-temperature, low-pressure refrigerant enters the refrigerator and freezer evaporators, and after heat exchange, the refrigerant re-enters the compressor, completing the refrigeration cycle.

[0050] Therefore, embodiments of this application provide a refrigerator, a temperature compensation system, a freezing capacity testing method, a freezing control method, and a medium, which will be described in detail below.

[0051] like Figure 1 As shown, the temperature compensation system includes:

[0052] Compensating heater 110 is used to provide heat compensation to the temperature of the refrigerator compartment;

[0053] A first compensation circuit L1 is connected to the compensation heater 110;

[0054] The second compensation circuit L2 is connected in parallel with the first compensation circuit and is connected to the compensation heater 110.

[0055] A first switch 120 is configured to select either the first compensation circuit L1 or the second compensation circuit L2 to be activated based on the ambient temperature; and

[0056] The second switch 130 is disposed on the second compensation circuit L2 and is configured to open or close according to the temperature of the refrigerator compartment.

[0057] Combination Figure 1 and Figure 2 When the ambient temperature is lower than the first preset temperature, the first switch 120 selects the first compensation circuit L1 to be turned on, so that the compensation heater 110 provides heat compensation to the refrigerator compartment.

[0058] Combination Figure 1 and Figure 3 As shown, when the ambient temperature is higher than the first preset temperature, the first switch 120 selects the second compensation circuit L2 to be turned on; and when the temperature of the refrigerator compartment is lower than the second preset temperature, the second switch 130 is closed so that the compensation heater 110 provides heat compensation to the refrigerator compartment.

[0059] Because the compressor operates at a very low rate when the ambient temperature is lower than the first preset temperature, it is difficult to meet the freezing requirements. Therefore, the first switch 120 selects the first compensation circuit L1 to be turned on, so that the compensation heater 110 provides heat compensation to the refrigerator compartment, thereby prompting the compressor to increase its operating rate. This enables the refrigerator to obtain more cooling capacity in the freezer compartment at low ambient temperatures, thus improving the freezing capacity of the freezer compartment.

[0060] When the ambient temperature is higher than the first preset temperature, the compressor's operating rate increases. However, when the refrigerator compartment temperature is lower than the second preset temperature, the compressor will stop operating once it reaches the set temperature. This will also cause the freezer compartment temperature to fail to meet the cooling requirements or the time required for the freezer compartment temperature to reach the required temperature to meet the time requirement. Therefore, in the technical solution of this application, after the ambient temperature is higher than the first preset temperature, based on the increased compressor operating rate, the first switch 120 selects the second compensation circuit L2 to be turned on. At this time, the second switch 130 is closed or opened according to the refrigerator compartment temperature. When the refrigerator compartment temperature is lower than the second preset temperature, the second switch 130 is closed, so that the compensation heater 110 provides heat compensation to the refrigerator compartment to increase the refrigerator compartment temperature, thereby increasing the compressor's operating rate and ensuring that the freezer compartment temperature reaches the cooling requirements or the time required for the freezer compartment temperature to reach the required temperature meets the time requirement.

[0061] In one embodiment, when the ambient temperature is equal to a first preset temperature, the first switch 120 can selectively activate the first compensation circuit L1, so that the compensation heater 110 provides heat compensation to the refrigerator compartment. Alternatively, when the ambient temperature is equal to the first preset temperature, the first switch 120 can selectively activate the second compensation circuit L2.

[0062] In some embodiments, when the temperature of the refrigerator compartment is equal to the second preset temperature, the second switch 130 is closed so that the compensation heater 110 provides heat compensation to the refrigerator compartment; or when the temperature of the refrigerator compartment drops to equal to the second preset temperature, the second switch 130 remains in the open state until the temperature of the refrigerator compartment drops below the second preset temperature, at which point the second switch 130 closes.

[0063] As an optional implementation of the above embodiments, the first preset temperature ranges from 8 to 10°C; the second preset temperature ranges from 0°C to 0.5°C.

[0064] In some embodiments, the first preset temperature is 10°C. That is, when the ambient temperature is below 10°C, the compressor’s operating rate decreases. At this time, the first compensation circuit L1 is activated by the first switch 120, which causes the temperature inside the refrigerator compartment to increase, so as to meet the compressor’s operating requirements and increase the operating rate to meet the cooling requirements of the freezer compartment.

[0065] In some embodiments, the first preset temperature is 10°C, that is, when the ambient temperature is higher than 10°C, the compressor's operating rate will increase. At this time, the second compensation circuit L2 is activated through the first switch 120. The second preset temperature is 0°C. When the temperature inside the refrigerator compartment drops to 0°C or below, the compressor will automatically stop, making it difficult to meet the cooling demand of the freezer compartment. Therefore, when the temperature inside the refrigerator compartment drops to 0°C or below, the second switch 130 is closed, causing the second compensation circuit L2 to activate the compensation heater 110, increasing the temperature inside the refrigerator compartment, so that the temperature inside the refrigerator compartment rises to meet the compressor's operating requirements, increasing the operating rate, and thus also cooling the freezer compartment.

[0066] The specific values ​​for the first and second preset temperatures are set according to the specific performance of the refrigerator. For example, the first preset temperature can be set to 8℃ or 9℃, and the second preset temperature can be set to 0.3℃, etc.

[0067] In some embodiments, combined with Figure 1 and Figure 4As shown, when the temperature of the refrigerator compartment is higher than the third preset temperature, the temperature inside the refrigerator compartment meets the compressor's starting conditions. Therefore, the second switch 130 is opened, causing the compensation heater 110 to stop providing heat compensation to the refrigerator compartment, thus preventing the temperature inside the refrigerator compartment from becoming too high. For example, the value of the third preset temperature is in the range of 3.5-4.5℃. For example, the third preset temperature is 4℃. When the temperature of the refrigerator compartment is higher than 4℃, the temperature inside the refrigerator compartment meets the compressor's starting conditions. Therefore, the second switch 130 is opened, causing the compensation heater 110 to stop providing heat compensation to the refrigerator compartment, thus preventing overheating inside the refrigerator compartment.

[0068] In some embodiments, when the temperature of the refrigerator compartment rises back to a third preset temperature, the temperature inside the refrigerator compartment meets the compressor's starting conditions, and the second switch 130 is opened, so that the compensation heater 110 stops providing heat compensation to the refrigerator compartment, preventing the temperature inside the refrigerator compartment from becoming too high. Alternatively, in some embodiments, when the temperature of the refrigerator compartment rises back to the third preset temperature, the second switch 130 remains closed, so that the compensation heater 110 continues to provide heat compensation to the refrigerator compartment until the temperature of the refrigerator compartment rises back above the third preset temperature.

[0069] In the above embodiments, the ambient temperature can be obtained by the refrigerator from a weather system via a network module. The temperature inside the refrigerator compartment can be collected by a temperature acquisition device built into the refrigerator compartment.

[0070] As an optional implementation of the above embodiments, such as Figure 5 As shown, the temperature compensation system further includes a first temperature sensor 122 and a second temperature sensor 132; the first temperature sensor 122 is configured to collect ambient temperature; the second temperature sensor 132 is configured to collect the temperature of the refrigerator compartment. In an embodiment, the first temperature sensor 122 can be placed in a non-compartment of the refrigerator, in a natural environment, such as the top of the refrigerator, to collect ambient temperature. The second temperature sensor 132 is built into the refrigerator compartment to collect the temperature inside the refrigerator compartment.

[0071] In some embodiments, the temperature compensation system further includes a controller for receiving the ambient temperature and the temperature of the refrigerator compartment collected by the first temperature sensor 122 and the second temperature sensor 132, and controlling the first switch 120 and the second switch 130 to perform corresponding actions based on the ambient temperature and the temperature inside the refrigerator compartment, so that the compensation heater 110 provides heat to the refrigerator compartment or the compensation heater stops providing heat to the refrigerator compartment.

[0072] As an optional implementation of the above embodiments, such as Figure 5As shown, the first switch 120 is a first temperature control switch; the first temperature control switch includes the first temperature sensor 122 and the first switching element 121; the first switching element 121 is configured to select either the first compensation circuit L1 or the second compensation circuit L2 to be turned on according to the ambient temperature; and / or

[0073] The second switch 130 is a second temperature control switch, which includes the two temperature sensors and the second switch element 131; the second switch element 131 is configured to open or close according to the temperature of the refrigerator compartment.

[0074] That is, in the embodiments, both the first switch 120 and the second switch 130 can be automatically controlled temperature switches, such as thermal switches. When the ambient temperature of the first temperature sensor 122 is higher than the first preset temperature, the first switch 121 automatically turns on the second compensation circuit L2; when the ambient temperature of the first temperature sensor 122 is lower than the first preset temperature, the first switch 121 automatically turns on the first compensation circuit L1.

[0075] When the temperature of the refrigerator compartment of the second temperature sensor 132 is higher than the third preset temperature, the second switch 131 automatically disconnects; when the temperature of the refrigerator compartment of the second temperature sensor 132 is lower than the second preset temperature, the second switch 131 automatically closes.

[0076] As an optional implementation of the above embodiments, the temperature compensation system further includes a power supply configured to provide electrical energy to the compensation heater 110 via the first compensation circuit L1 or the second compensation circuit L2. In this embodiment, the compensation heater 110 is an electric heater, such as one containing an electric heating wire, which converts electrical energy into heat energy. In this embodiment, when the first switch 120 is turned on in the first compensation circuit L1, the compensation heater 110 receives the electrical energy provided by the power supply and begins heating; similarly, when the first switch 120 is turned on in the second compensation circuit L2 and the second switch 130 is closed, the compensation heater 110 also receives the electrical energy provided by the power supply and begins heating. When the first switch 120 is turned on in the second compensation circuit L2 and the second switch 130 is turned off, the power supply and the compensation heater 110 are not connected, and the compensation heater 110 stops providing heat to the refrigerator compartment. In this embodiment, the power supply can be a backup power supply or a 220V household power supply.

[0077] The temperature compensation system provided in this application can be used for freezing capacity testing or freezing control. Therefore, based on the temperature compensation system provided in this application, this application also proposes a freezing capacity testing method and a freezing control method.

[0078] The freezing capacity testing method provided in this application includes:

[0079] The compressor is controlled to start at a preset operating rate, and the temperature inside the freezer compartment and / or the rate of temperature decrease of the freezer compartment are obtained; the lowest temperature inside the freezer compartment and / or the rate of temperature decrease of the freezer compartment are the freezing capacity evaluation indicators at the preset operating rate.

[0080] Obtain the ambient temperature;

[0081] When the ambient temperature is lower than the first preset temperature, the first switch is controlled to select the first compensation circuit to be turned on, so that the compensation heater provides heat compensation to the refrigerator compartment;

[0082] When the ambient temperature is higher than the first preset temperature, the first switch is controlled to select the second compensation circuit to be turned on, and the temperature of the refrigerator compartment is obtained.

[0083] When the temperature of the refrigerator compartment is lower than the second preset temperature, the second switch is controlled to close so that the compensation heater provides heat compensation to the refrigerator compartment.

[0084] The freezing capacity testing method provided in this embodiment can be used under various operating conditions to test the freezing capacity at a preset operating rate. In this embodiment, the compressor starts at a preset operating rate, and a temperature compensation system ensures that the compressor can maintain this preset operating rate. When the ambient temperature is higher than a first preset temperature, the first switch is controlled to activate the first compensation circuit, so that the compensation heater provides heat compensation to the refrigerator compartment, ensuring that the temperature of the refrigerator compartment meets the compressor's starting conditions and maintains the preset operating rate. When the ambient temperature is higher than the first preset temperature, the first switch is controlled to activate the second compensation circuit, and the temperature of the refrigerator compartment is acquired. When the temperature of the refrigerator compartment is lower than a second preset temperature, the second switch is controlled to close, so that the compensation heater provides heat compensation to the refrigerator compartment, ensuring that the temperature of the refrigerator compartment meets the compressor's starting conditions and maintains the preset operating rate. This allows the refrigerator to test the freezing capacity of the freezer compartment at the preset operating rate.

[0085] For example, when testing the freezer compartment at ambient temperature or above, the temperature control system activates the second compensation circuit at ambient temperature or above. When the compressor operates at a preset operating rate, if the temperature inside the refrigerator compartment falls below a second preset temperature, the second switch closes to compensate for the heat supplied to the refrigerator compartment by the heater, allowing the compressor to start normally and maintain the preset operating rate. This enables the temperature control system to test the minimum temperature of the freezer compartment and / or the rate of temperature decrease in the freezer compartment at ambient temperature or above.

[0086] The freezing control method provided in this application includes:

[0087] Obtain the required temperature for the freezer compartment;

[0088] The compressor's operating rate is determined based on the required temperature.

[0089] Control the compressor to operate at the stated start-up rate;

[0090] Obtain the ambient temperature;

[0091] When the ambient temperature is lower than the first preset temperature, the first switch is controlled to select the first compensation circuit to be turned on, so that the compensation heater provides heat compensation to the refrigerator compartment;

[0092] When the ambient temperature is higher than the first preset temperature, the first switch is controlled to select the second compensation circuit to be turned on, and the temperature of the refrigerator compartment is obtained.

[0093] When the temperature of the refrigerator compartment is lower than the second preset temperature, the second switch is controlled to close so that the compensation heater provides heat compensation to the refrigerator compartment.

[0094] The freezing control method provided in this embodiment can be used under various operating conditions to enable the refrigerator to reach the required temperature. In this embodiment, after obtaining the required temperature of the refrigerator, the corresponding operating rate is determined, and the compressor operates at the operating rate. A temperature compensation system ensures that the compressor can maintain this operating rate so that the refrigerator can reach the required temperature. When the ambient temperature is higher than a first preset temperature, the first switch is controlled to select the first compensation circuit to conduct, so that the compensation heater provides heat compensation to the refrigerator compartment, ensuring that the temperature of the refrigerator compartment meets the compressor's starting conditions and maintaining the operating rate. When the ambient temperature is higher than the first preset temperature, the first switch is controlled to select the second compensation circuit to conduct, and the temperature of the refrigerator compartment is obtained. When the temperature of the refrigerator compartment is lower than a second preset temperature, the second switch is controlled to close, so that the compensation heater provides heat compensation to the refrigerator compartment, ensuring that the temperature of the refrigerator compartment meets the compressor's starting conditions and the preset operating rate. Thus, the refrigerator can maintain the operating rate while ensuring that the freezer compartment reaches the required temperature.

[0095] For example, when the freezer compartment cools from ambient temperature (or higher) to the required temperature, the operating rate is determined; the compressor is then controlled to operate at this operating rate. Through this temperature control system, when the ambient temperature is at or above ambient temperature, the first switch activates the second compensation circuit; when the compressor is operating at the operating rate, if the temperature inside the refrigerator compartment falls below a second preset temperature, the second switch closes to compensate for the heat supplied to the refrigerator compartment by the heater, allowing the compressor to start normally and maintain the operating rate. This ensures that the temperature control system can cool the refrigerator compartment to the required temperature when the ambient temperature is at or above ambient temperature, thus meeting the freezing requirements.

[0096] In this embodiment, a corresponding relationship is established between the required temperature and the operating rate. In the technical solution of this application embodiment, because a temperature compensation system is provided, the temperature inside the refrigerator compartment can be compensated; therefore, the operating rate is set to be only related to the required temperature of the freezer compartment. When the compressor is turned on, it can naturally provide cooling to the refrigerator compartment; and when the temperature inside the refrigerator compartment is low, heat compensation is provided through a compensating heater, without the need for the compressor to stop.

[0097] This application also proposes a freezing capacity testing or freezing control system, comprising: one or more processors; a memory; and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the processor to implement the freezing capacity testing or freezing control method as described above.
