[0045] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details.

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

[0046] Refrigerators are common household appliances used to preserve, refrigerate or freeze food, medicines, etc. Single-system refrigerators are a common type of refrigerator, which uses a compressor to provide cooling to the refrigerator and freezer. Since the temperature of the refrigerator can easily reach the preset temperature range, the compressor is turned on at a low rate, making it difficult for the freezer to meet the refrigeration requirements.

[0047] In some technologies, in a low-temperature environment, a compensation heater is provided to provide thermal compensation to the cold storage room to increase the start-up rate of the compressor, thereby increasing the refrigeration requirements of the freezer in a low-temperature environment. However, in some cases, such as when testing the refrigeration capacity of the freezer, the temperature of the freezer needs to drop rapidly from a higher temperature (close to or above normal temperature) to below -18°C; however, when the compressor is turned on, the temperatures of the freezer and the cold storage room drop at the same time; however, the cold demand of the cold storage room is limited, which leads to a low start-up rate of the compressor, and the temperature of the freezer cannot meet the requirement of dropping rapidly from a higher temperature (close to or above normal temperature) to below -18°C or cannot drop to -18°C.

[0048] To this end, the technical solution of the embodiment of the present application provides a temperature compensation system, which can simultaneously control the start and stop of the compensation heater of the cold storage room according to the external ambient temperature and the internal temperature of the cold storage room, thereby increasing the start-up rate of the compressor to meet the freezing capacity test requirements or freezing and refrigeration needs.

[0049] A single-system refrigerator is a common type of refrigerator, which uses a compressor to provide cold air to the refrigerator and freezer. The refrigeration system of a single-system refrigerator includes: a compressor, a condenser, a throttling device, a freezing evaporator and a refrigerating evaporator. The compressor is connected to the freezing evaporator and the refrigerating evaporator; the freezing evaporator is configured to provide cold air to the freezing chamber, and the refrigerating evaporator is configured to provide cold air to the refrigerating chamber. The compressor is used to compress the refrigerant; the compressed refrigerant enters the condenser to release heat, and then is throttled and reduced in pressure to a low-temperature and low-pressure refrigerant through the throttling device; the low-temperature and low-pressure refrigerant enters the refrigerating evaporator and the freezing evaporator, and the refrigerant after heat exchange re-enters the compressor to complete the refrigeration cycle.

[0050] To this end, the embodiments of the present application provide a refrigerator, a temperature compensation system, a freezing capacity testing method, a freezing control method and a medium, which are described in detail below.

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

[0052] A compensation heater 110, used to provide heat compensation for the temperature of the refrigerating chamber;

[0053] A first compensation loop L1, wherein the first compensation loop L1 is connected to the compensation heater 110;

[0054] A second compensation loop L2, the second compensation loop L2 is connected in parallel with the first compensation circuit and connected to the compensation heater 110;

[0055] A first switch 120, wherein the first switch 120 is configured to select either the first compensation loop L1 or the second compensation loop L2 to be turned on according to ambient temperature; and

[0056] The second switch 130 is disposed on the second compensation loop L2 and is configured to be opened or closed according to the temperature of the refrigerating chamber.

[0057] Combination Figure 1 and Figure 2 , when the ambient temperature is lower than a first preset temperature, the first switch 120 selects the first compensation loop L1 to be turned on, so that the compensation heater 110 provides thermal compensation to the refrigerating chamber;

[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 loop L2 to be turned on; and when the temperature of the refrigerating chamber is lower than the second preset temperature, the second switch 130 is closed so that the compensation heater 110 provides thermal compensation to the refrigerating chamber.

[0059] Because when the ambient temperature is lower than the first preset temperature, the startup rate of the compressor is very low and it is difficult to meet the freezing requirements; for this reason, the first switch 120 selects the first compensation loop L1 to be turned on, so that the compensation heater 110 provides thermal compensation to the refrigerating chamber to prompt the compressor to increase the startup rate, thereby enabling the freezer chamber to obtain more cold air at low ambient temperatures and improving the freezing capacity of the freezer chamber.

[0060] When the ambient temperature is higher than the first preset temperature, the start-up rate of the compressor increases. However, when the temperature of the cold storage chamber is lower than the second preset temperature, the compressor will shut down due to reaching the temperature, which will also cause the temperature of the freezer chamber to be difficult to meet the refrigeration requirements or the time for the temperature of the freezer chamber to reach the required temperature cannot meet the time requirements. For this reason, in the technical solution of the present application, after the ambient temperature is higher than the first preset temperature, on the basis of the increase in the start-up rate of the compressor, the first switch 120 selects the second compensation circuit L2 to be turned on, and at this time, the closing or opening of the second switch 130 is controlled according to the temperature of the cold storage chamber; when the temperature of the cold storage chamber is lower than the second preset temperature, the second switch 130 is closed, so that the compensation heater 110 provides thermal compensation to the cold storage chamber to increase the temperature of the cold storage chamber, thereby increasing the start-up rate of the compressor, and the temperature of the freezer chamber reaches the refrigeration requirements or the time for the temperature of the freezer chamber to reach the required temperature meets the time requirements.

[0061] In an embodiment, when the ambient temperature is equal to the first preset temperature, the first switch 120 may select the first compensation loop L1 to be turned on, so that the compensation heater 110 provides thermal compensation to the refrigerating chamber. Alternatively, when the ambient temperature is equal to the first preset temperature, the first switch 120 may select the second compensation loop L2 to be turned on.

[0062] In some embodiments, when the temperature of the refrigerated chamber is equal to a second preset temperature, the second switch 130 is closed so that the compensation heater 110 provides thermal compensation to the refrigerated chamber; or when the temperature of the refrigerated chamber drops to equal to the second preset temperature, the second switch 130 is still in an open state until the temperature of the refrigerated chamber drops below the second preset temperature, and the second switch 130 is closed.

[0063] As an optional implementation of the above embodiment, the value range of the first preset temperature is 8-10°C; the value range of the second preset temperature is 0°C to 0.5°C.

[0064] In some embodiments, the first preset temperature is 10°C, that is, when the ambient temperature is lower than 10°C, the startup rate of the compressor decreases. At this time, the first compensation loop L1 is turned on through the first switch 120, which causes the temperature in the refrigerator to increase to meet the startup requirements of the compressor, and increases the startup rate to meet the refrigeration requirements of the freezer.

[0065] In some embodiments, the first preset temperature is 10°C, that is, when the ambient temperature is higher than 10°C, the startup rate of the compressor will increase. At this time, the second compensation loop L2 is turned on through the first switch 120; the second preset temperature is 0°C; when the temperature in the cold storage room is as low as 0°C or below, the compressor will automatically shut down, making it difficult to meet the refrigeration demand of the freezer; for this reason, when the temperature in the cold storage room is as low as 0°C or below, the second switch 130 is closed, so that the second compensation loop L2 turns on the compensation heater 110, increases the temperature in the cold storage room, and makes the temperature of the cold storage room rise to meet the compressor startup demand, increases the startup rate, and thus also cools the freezer.

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

[0067] In some embodiments, in combination Figure 1 and Figure 4As shown, when the temperature of the refrigerator compartment is higher than the third preset temperature, the temperature in the refrigerator compartment meets the start-up condition of the compressor, and then the second switch 130 is disconnected, so that the compensation heater 110 stops providing thermal compensation to the refrigerator compartment to avoid the temperature in the refrigerator compartment being too high. For example, the value range of the third preset temperature is 3.5-4.5°C. For example, the third preset temperature is 4°C; when the temperature of the refrigerator compartment is higher than 4°C, the temperature in the refrigerator compartment meets the start-up condition of the compressor, and then the second switch 130 is disconnected, so that the compensation heater 110 stops providing thermal compensation to the refrigerator compartment to avoid overheating in the refrigerator compartment.

[0068] In some embodiments, when the temperature of the refrigerating chamber rises back to the third preset temperature, the temperature in the refrigerating chamber meets the start-up condition of the compressor, and then the second switch 130 is disconnected, so that the compensation heater 110 stops providing thermal compensation to the refrigerating chamber to prevent the temperature in the refrigerating chamber from being too high. Or in some embodiments, when the temperature of the refrigerating chamber rises back to the third preset temperature, the second switch 130 is still in a closed state, so that the compensation heater 110 continues to provide thermal compensation to the refrigerating chamber until the temperature of the refrigerating chamber rises back to exceed the third preset temperature.

[0069] In the above embodiment, the ambient temperature can be obtained by the refrigerator from the weather system through the network module. The temperature in the refrigerated room can be collected by a temperature collection device built into the refrigerated room.

[0070] As an optional implementation of the above embodiment, 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 the ambient temperature; the second temperature sensor 132 is configured to collect the temperature of the refrigerating chamber. In an embodiment, the first temperature sensor 122 can be arranged in a non-compartmental room of the refrigerator, placed in a natural environment, such as the top of the refrigerator, to collect the ambient temperature. The second temperature sensor 132 is built into the refrigerating chamber to collect the temperature in the refrigerating chamber.

[0071] In some embodiments, the temperature compensation system also includes a controller, which is used to receive the ambient temperature and the temperature of the cold storage chamber collected by the first temperature sensor 122 and the second temperature sensor 132, and control the first switch 120 and the second switch 130 to perform corresponding actions according to the ambient temperature and the temperature in the cold storage chamber, so that the compensation heater 110 provides heat to the cold storage chamber or the compensation heater stops providing heat to the cold storage chamber.

[0072] As an optional implementation of the above embodiment, Figure 5As shown, the first switch 120 is a first temperature-controlled switch; the first temperature-controlled switch includes the first temperature sensor 122 and a first switch element 121; the first switch element 121 is configured to select any one of the first compensation loop L1 and the second compensation loop L2 to be turned on according to the ambient temperature; and / or

[0073] The second switch 130 is a second temperature-controlled switch, which includes the two temperature sensors and a second switch element 131 ; the second switch element 131 is configured to be opened or closed according to the temperature of the refrigerating chamber.

[0074] That is, in the embodiment, the first switch 120 and the second switch 130 can both be automatically controlled temperature control 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 loop 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 loop L1.

[0075] When the temperature of the refrigerating chamber detected by the second temperature sensor 132 is higher than the third preset temperature, the second switch 131 is automatically disconnected; when the temperature of the refrigerating chamber detected by the second temperature sensor 132 is lower than the second preset temperature, the second switch 131 is automatically closed.

[0076] As an optional implementation of the above embodiment, the temperature compensation system further includes a power supply, and the power supply is configured to provide electric energy to the compensation heater 110 through the first compensation loop L1 or the second compensation loop L2. In this embodiment, the compensation heater 110 is an electric heating heater, such as containing an electric heating wire, which converts electric energy into heat energy. In the embodiment, when the power supply turns on the first compensation loop L1 at the first switch 120, the compensation heater 110 obtains the electric energy provided by the power supply and starts heating; when the power supply turns on the second compensation loop L2 at the first switch 120 and the second switch 130 is closed, the compensation heater 110 also obtains the electric energy provided by the power supply and starts heating. When the power supply turns on the second compensation loop L2 at the first switch 120 and the second switch 130 is disconnected, the power supply is not connected to the compensation heater 110, and then the compensation heater 110 stops providing heat to the refrigeration chamber. In the embodiment, the power supply can be a backup power supply or a 220V civil power supply.

[0077] The temperature compensation system provided in the embodiment of the present application can be used in refrigeration capacity testing or refrigeration control. To this end, based on the temperature compensation system provided in the embodiment of the present application, the embodiment of the present application also proposes a refrigeration capacity testing method and a refrigeration control method.

[0078] The freezing capacity testing method provided in the embodiment of the present application includes:

[0079] Controlling the compressor to start at a preset start-up rate, and obtaining the temperature in the freezer compartment and / or the rate of decrease of the temperature in the freezer compartment; the lowest temperature in the freezer compartment and / or the rate of decrease of the temperature in the freezer compartment are evaluation indicators of the refrigeration capacity at the preset start-up rate;

[0080] Get the ambient temperature;

[0081] When the ambient temperature is lower than a first preset temperature, controlling the first switch to select the first compensation circuit to be turned on, so that the compensation heater provides thermal compensation to the refrigerating chamber;

[0082] When the ambient temperature is higher than the first preset temperature, controlling the first switch to select the second compensation circuit to be turned on, and obtaining the temperature of the refrigerating chamber;

[0083] When the temperature of the refrigerating chamber is lower than a second preset temperature, the second switch is controlled to be closed so that the compensation heater provides thermal compensation to the refrigerating chamber.

[0084] The freezing capacity test method provided in this embodiment can be used under various working conditions to test the freezing capacity under a preset start-up rate. In an embodiment, the compressor is started at a preset start-up rate, and the temperature compensation system is used to ensure that the compressor can maintain the preset start-up rate. When the ambient temperature is higher 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 thermal compensation to the refrigerating chamber, so that the temperature of the refrigerating chamber meets the start-up condition of the compressor and maintains the preset start-up rate; 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 refrigerating chamber is obtained; when the temperature of the refrigerating chamber is lower than the second preset temperature, the second switch is controlled to be closed, so that the compensation heater provides thermal compensation to the refrigerating chamber, so that the temperature of the refrigerating chamber meets the start-up condition of the compressor and maintains the preset start-up rate. In this way, the refrigerator can test the freezing capacity of the freezer under the preset start-up rate.

[0085] For example, when testing the freezer compartment at an ambient temperature of normal temperature or higher than normal temperature, the first switch selects the second compensation circuit to be turned on through the temperature control system at an ambient temperature of normal temperature or higher than normal temperature; when the compressor is running at a preset start-up rate, when the temperature in the refrigerator compartment reaches a temperature lower than the second preset temperature, the second switch is closed, and the heat provided by the compensation heater to the refrigerator compartment is used to enable the compressor to start normally to maintain the preset start-up rate, so that the temperature control system can test the minimum temperature of the freezer compartment and / or the rate of decrease of the temperature of the freezer compartment at an ambient temperature of normal temperature or higher than normal temperature.

[0086] The refrigeration control method provided in the embodiment of the present application includes:

[0087] Get the required temperature of the freezer compartment;

[0088] determining the start-up rate of the compressor according to the required temperature;

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

[0090] Get the ambient temperature;

[0091] When the ambient temperature is lower than a first preset temperature, controlling the first switch to select the first compensation circuit to be turned on, so that the compensation heater provides thermal compensation to the refrigerating chamber;

[0092] When the ambient temperature is higher than the first preset temperature, controlling the first switch to select the second compensation circuit to be turned on, and obtaining the temperature of the refrigerating chamber;

[0093] When the temperature of the refrigerating chamber is lower than a second preset temperature, the second switch is controlled to be closed so that the compensation heater provides thermal compensation to the refrigerating chamber.

[0094] The freezing control method provided in this embodiment can be used under various working conditions to enable the refrigerator to reach the required temperature. In the embodiment, after the required temperature of the refrigerator is obtained, the corresponding start-up rate is determined, the compressor runs at the start-up rate, and the temperature compensation system is used to ensure that the compressor can maintain the start-up rate to start, so that the refrigerator can reach the required temperature. When the ambient temperature is higher 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 thermal compensation to the refrigerating chamber, so that the temperature of the refrigerating chamber meets the start-up condition of the compressor, and the start-up rate is maintained; 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 refrigerating chamber is obtained; when the temperature of the refrigerating chamber is lower than the second preset temperature, the second switch is controlled to be closed, so that the compensation heater provides thermal compensation to the refrigerating chamber, so that the temperature of the refrigerating chamber meets the start-up condition of the compressor, and the start-up rate is preset. In this way, the refrigerator can maintain the start-up rate while enabling the freezer to reach the required temperature.

[0095] For example, when the freezing chamber is lowered from normal temperature or higher than normal temperature to the required temperature, the start-up rate is determined; the compressor is controlled to operate at the start-up rate. Through the temperature control system at normal temperature or higher than normal temperature, the first switch selects the second compensation circuit to be turned on; when the compressor operates at the start-up rate, when the temperature in the refrigerated chamber reaches a temperature lower than the second preset temperature, the second switch is closed, and the heat provided by the compensation heater to the refrigerated chamber is provided, so that the compressor can be started normally to maintain the start-up rate, so that the temperature control system can be lowered to the required temperature at normal temperature or higher than normal temperature to meet the freezing demand.

[0096] In the embodiment, a corresponding relationship is set between the demand temperature and the start-up rate. In the technical solution of the embodiment of the present application, since a temperature compensation system is provided, the temperature in the refrigerating chamber can be compensated; therefore, the start-up rate is set to be related only to the demand temperature of the freezing chamber. When the compressor is turned on, it can naturally provide cooling to the refrigerating chamber; and when the temperature in the refrigerating chamber is low, thermal compensation is provided by the compensation heater without stopping the compressor.
