Description

Technical Field

[0001] This application belongs to the field of electrical technology, and in particular relates to a control method, device, storage device and storage medium for a storage device. Background Technology

[0002] In related technologies, due to the increased volume of storage equipment, the refrigeration fan needs to be set to a higher speed to drive air circulation, which results in increased power consumption, higher noise, and poorer preservation effect when the fan is working. Summary of the Invention

[0003] This application proposes a control method, device, storage device, and storage medium for storage equipment, in order to solve the problems of increased power consumption, high noise, and poor preservation effect of the fan when the volume of the storage equipment is increased in the related technology.

[0004] In a first aspect, this application provides a control method for a storage device, the storage device comprising: a housing forming a compartment; a compressor disposed within the housing; an evaporator disposed within the housing; a first fan disposed at the rear end of the evaporator; a second fan disposed at the front end of the evaporator; and a temperature sensor for measuring the temperature of the compartment; wherein the evaporator, the first fan, and the second fan are disposed within an air duct of the housing;

[0005] The method includes:

[0006] Obtain the temperature measurement value and cooling rate of the chamber;

[0007] The compressor, the first fan, and the second fan are controlled to start and stop based on the measured temperature value, the cooling rate, and the preset start-up and shutdown temperatures.

[0008] The control method for the storage device provided in this application obtains the temperature measurement value and cooling rate of the compartment. Based on the temperature measurement value, cooling rate, preset start-up temperature and shutdown temperature, the method controls the start-up and shutdown of the compressor, the first fan and the second fan. According to the cooling rate in the compartment, the start-up, shutdown and speed of the compressor, the first fan and the second fan are adjusted in a stepwise manner, realizing the coupled control of air volume by the dual fans and the compressor, improving the cooling efficiency and reducing the overall energy consumption of the machine.

[0009] According to one embodiment of this application, controlling the start and stop of the compressor, the first fan, and the second fan based on the measured temperature value, the cooling rate, and the preset start-up and stop-down temperatures includes:

[0010] When the temperature measurement value of the chamber reaches the start-up temperature, the compressor and the first fan are controlled to start.

[0011] If the cooling rate exceeds the first threshold, the second fan is controlled to stop working;

[0012] Determine whether the measured temperature value has reached a first temperature. When the measured temperature value reaches the first temperature, control the compressor to stop, the first fan to stop, and the second fan to start. The first temperature is the sum of the shutdown point temperature and the first temperature value.

[0013] When the measured temperature reaches the shutdown point temperature, the second fan is controlled to stop.

[0014] In the above technical solution, when the temperature measurement value reaches the start-up temperature, the compressor and the first fan are started. When the cooling rate is greater than the first threshold, the second fan is stopped. This can reduce unnecessary energy consumption. By stopping the compressor and the first fan and starting the second fan when the temperature measurement value reaches the first temperature, the remaining cold energy is fully utilized, improving the air supply efficiency and preservation effect of the storage equipment, and reducing the energy consumption and noise of the storage equipment.

[0015] According to one embodiment of this application, after controlling the compressor and the first fan to start when the temperature measurement value of the room reaches the start-up temperature, the method further includes:

[0016] If the cooling rate is less than or equal to the first threshold, control the second fan to start;

[0017] Determine whether the cooling rate exceeds a second threshold, wherein the second threshold is greater than the first threshold;

[0018] If the cooling rate exceeds the second threshold, determine whether the temperature measurement value has reached the first temperature. If the temperature measurement value reaches the first temperature, control the compressor to stop and the first fan to stop.

[0019] When the measured temperature reaches the shutdown point temperature, the second fan is controlled to stop.

[0020] In the above technical solution, when the cooling rate is less than or equal to the first threshold, the second fan is started, realizing adaptive control of the room temperature. The simultaneous operation of the first and second fans can reduce speed and temperature fluctuations, reduce noise, and improve refrigeration efficiency and preservation effect compared to the operation of a single fan alone.

[0021] According to one embodiment of this application, after determining whether the cooling rate exceeds a second threshold, the method further includes:

[0022] If the cooling rate does not exceed the second threshold, control the second fan to operate at a higher speed;

[0023] Determine whether the cooling rate exceeds the third threshold;

[0024] If the cooling rate exceeds the third threshold, determine whether the temperature measurement value has reached the first temperature;

[0025] When the measured temperature reaches the first temperature, the compressor and the first fan are controlled to stop.

[0026] When the measured temperature reaches the shutdown point temperature, the second fan is controlled to stop.

[0027] In the above technical solution, if the cooling rate does not exceed the second threshold, the second fan is controlled to operate at a higher speed. This allows for adaptive control of the room temperature based on actual cooling needs. Furthermore, the simultaneous operation of the first and second fans, compared to a single fan operating alone, can reduce fan speed and temperature fluctuations, decrease noise and overall energy consumption, and improve cooling efficiency and preservation effect.

[0028] According to one embodiment of this application, after determining whether the temperature measurement value has reached a first temperature, the method further includes:

[0029] If the measured temperature does not reach the first temperature, the compressor is controlled to run at low speed until the measured temperature reaches the first temperature, at which point the compressor and the first fan are controlled to stop.

[0030] When the measured temperature reaches the shutdown point temperature, the second fan is controlled to stop.

[0031] In the above technical solution, when the temperature measurement value has not reached the first temperature, the compressor is controlled to run at a low speed, which can continue to cool the food while reducing energy consumption. This achieves adaptive control of the room temperature. Moreover, when the compressor runs at a low speed, the air speed is lower and the temperature fluctuation range is smaller, which reduces the possibility of high air speed blowing directly on the food and improves energy efficiency and preservation effect.

[0032] According to one embodiment of this application, after determining whether the cooling rate exceeds a third threshold, the method further includes:

[0033] If the cooling rate does not exceed the third threshold, the defrosting judgment logic is executed.

[0034] In the above technical solution, if the cooling rate does not exceed the third threshold, the defrosting judgment logic is executed, which can perform the defrosting operation in a timely manner, improve the cooling efficiency, and reduce unnecessary overall energy consumption.

[0035] According to one embodiment of this application, controlling the start and stop of the compressor, the first fan, and the second fan based on the measured temperature value, the cooling rate, and the preset start-up and stop-down temperatures includes:

[0036] If the measured temperature value does not reach the power-on temperature, determine whether the measured temperature value is greater than the set temperature.

[0037] When the measured temperature value is greater than the set temperature, the compressor is not started, and the first fan or the second fan is started.

[0038] Determine whether the measured temperature value has reached the shutdown point temperature;

[0039] When the measured temperature reaches the shutdown point temperature, the first fan or the second fan is turned off; or...

[0040] If the measured temperature does not reach the shutdown point temperature, the compressor is controlled to run at low speed until the measured temperature reaches the first temperature, at which point the compressor is controlled to stop, the first fan is stopped, and the second fan is started.

[0041] When the measured temperature reaches the shutdown point temperature, the second fan is turned off.

[0042] In the above technical solution, if the temperature measurement value does not reach the start-up temperature, it is determined whether the temperature measurement value is greater than the set temperature; if the temperature measurement value is greater than the set temperature, the start and stop of the compressor, the first fan and the second fan are controlled to achieve a short-term cooling and temperature reduction, so that the temperature in the room reaches the compressor shutdown temperature, thereby improving the cooling efficiency and reducing the overall energy consumption of the unit.

[0043] In a second aspect, this application provides a control device for a storage device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the control method for the storage device as described in the first aspect above.

[0044] Thirdly, this application provides a storage device, comprising: a housing forming a compartment; a compressor disposed within the housing; an evaporator disposed within the housing; a first fan disposed at the rear end of the evaporator; a second fan disposed at the front end of the evaporator; a temperature sensor for measuring the temperature of the compartment; and a control device for the storage device as described in the second aspect;

[0045] The evaporator, the first fan, and the second fan are arranged in the air duct of the housing. The air duct has a return air inlet and an air outlet. The return air inlet is located on the side closer to the second fan, and the air outlet is located on the side closer to the first fan.

[0046] Fourthly, this application provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the control method for the storage device as described in the first aspect above.

[0061] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0062] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0063] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0064] The control method for storage devices provided in this application embodiment can be executed by a controller or a functional module or entity in the controller that can implement the control method for the storage device. The controller mentioned in this application embodiment includes, but is not limited to, the controller in the storage device, the processor in the storage device, the edge server, the backend server, the cloud server, etc. The control method for storage devices provided in this application embodiment will be described below with the controller as the execution subject as an example.

[0065] The storage device in this embodiment can be understood as a refrigeration storage device in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. The storage devices have diverse structural forms and a wide range of applications.

[0066] In related technologies, refrigeration systems are divided into air-cooled refrigeration systems and direct-cooled refrigeration systems. Direct-cooled refrigeration systems achieve cooling by cooling through an evaporator, while air-cooled refrigeration systems use a fan installed on the evaporator to circulate air in the refrigeration cycle and blow the air over the surface of the evaporator, causing the refrigerant to absorb heat and evaporate into a gaseous state. The fan helps maintain airflow inside the evaporator, thereby ensuring that the refrigerant on the evaporator surface can absorb enough heat and transfer it to the refrigeration cycle. The operation of the fan will cool down the refrigeration equipment.

[0067] In existing air-cooled refrigeration systems, the fan is typically installed at the rear of the evaporator. After the fan starts running, a low-pressure zone and a high-pressure zone are formed on the front and rear sides respectively. The pressure difference between them enables air circulation within the refrigerator compartment. The warmer air inside the refrigerator compartment passes through the return air vent, exchanges heat with the evaporator to become cooler air, and then passes through the fan and air duct outlet to cool the food inside the refrigerator compartment.

[0068] Because modern refrigerators prioritize large capacity and partitioned storage, the cooling compartments are large and multi-zoned. This results in a significant pressure drop and reduced airflow velocity within the compartments after the air is pressurized by the fan. Consequently, the airflow velocity is very low when the recirculated air reaches the return air vent. To ensure sufficient air passes through the evaporator and achieves adequate heat exchange, the cooling fan needs to operate at a higher speed to drive air circulation, further increasing power consumption and noise levels. Additionally, increasing the fan speed leads to greater air pressure and velocity on the outlet side, causing larger temperature fluctuations within the compartment. Furthermore, the high airflow blowing on the surface of food, such as vegetables, causes rapid moisture loss, resulting in poor preservation.

[0069] To address the aforementioned problems, embodiments of this application provide a control method for storage devices. The control method, apparatus, storage device, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments and application scenarios.

[0070] Figure 1 This is one of the flowcharts illustrating the control method for a storage device provided in some embodiments of this application, such as... Figure 1 As shown, the control method for the storage device includes steps 110 and 120.

[0071] Step 110: Obtain the temperature measurement value and cooling rate of the chamber;

[0072] The storage equipment includes a housing, a compressor, an evaporator, a first fan, a second fan, and a temperature sensor. The housing is used to form a compartment, and the compressor and evaporator are located inside the housing.

[0073] Figure 2 These are schematic diagrams of the structure of storage devices provided in some embodiments of this application, such as... Figure 2As shown, the storage device 1 includes a housing 10, an evaporator 20, a first fan 30, a second fan 40, a compressor, and a temperature sensor (not shown in the figure). The housing 10 includes a refrigerator compartment 101 and a freezer compartment 102. The evaporator 20, the first fan 30, and the second fan 40 are disposed in the refrigerator air duct of the housing 10. The refrigerator air duct is provided with a return air inlet and an air outlet. The first fan 30 is disposed at the rear end of the evaporator, and the air outlet is located on the side close to the first fan 30. The second fan 40 is disposed at the front end of the evaporator, and the return air inlet is located on the side close to the second fan 40.

[0074] It is understandable that the compressor is one of the key components in storage device 1. It is usually electrically driven. The main function of the compressor is to draw in low-temperature, low-pressure refrigerant gas and compress it into high-temperature, high-pressure gas. During the compression of the refrigerant gas, the compressor can release heat and transfer the heat to the environment outside the storage device 1. The operation of the compressor will cause the storage device 1 to heat up.

[0075] Evaporator 20 absorbs heat from storage device 1 through the refrigerant evaporation process, and the operation of evaporator 20 will cool down storage device 1.

[0076] Optionally, the compartments include at least one of a refrigerated compartment, a variable temperature compartment, and a frozen compartment.

[0077] Temperature sensors are used to measure the temperature of a room. Temperature sensors can be thermistor sensors, semiconductor temperature sensors, digital temperature sensors, etc.

[0078] It should be noted that the evaporator 20, the first fan 30 and the second fan 40 are installed in the air duct of the housing 10. The air duct is provided with a return air port and an air outlet. The first fan 30 is located at the rear end of the evaporator 20 and the air outlet is located on the side close to the first fan 30. The second fan 40 is located at the front end of the evaporator 20 and the return air port is located on the side close to the second fan 40.

[0079] It is worth noting that the storage device 1 in this embodiment can be a vending machine. The temperature of the vending machine's compartment can be below 0 degrees Celsius. In some embodiments, the temperature of the vending machine's compartment can be from -5°C to -30°C, such as -25°C. The vending machine is used to sell frozen items, such as ice cream and ice cubes.

[0080] It's easy to understand that the controller acquires the temperature measurement values ​​from the room's temperature sensor in real time, and calculates the cooling rate based on the temperature measurement values ​​and time. For example, the controller acquires the temperature measurement difference T within a preset time period t, and the formula for calculating the cooling rate v is as follows:

[0081]

[0082] Where t represents the preset time period, T represents the temperature difference over the preset time period, and v represents the cooling rate over the preset time period.

[0083] Step 120: Control the start and stop of the compressor, the first fan and the second fan according to the temperature measurement value, the cooling rate, the preset start-up temperature and the shutdown temperature.

[0084] Furthermore, the controller determines whether the room temperature has reached the preset compressor start-up temperature based on the temperature measurement value. If the temperature measurement value has not reached the start-up temperature, it determines whether the temperature measurement value is greater than the preset compressor shutdown temperature. If the temperature measurement value is greater than the preset compressor shutdown temperature, it controls the compressor not to start and starts the first fan 30 or the second fan 40. After a period of time, it determines whether the temperature measurement value has reached the compressor shutdown temperature. When the temperature measurement value reaches the shutdown temperature, it shuts down the first fan 30 or the second fan 40. If the temperature measurement value has not reached the shutdown temperature, it controls the compressor to run at low speed until the temperature measurement value reaches the shutdown temperature, then controls the compressor to stop, the first fan 30 to stop, and the second fan 40 to stop.

[0085] If the measured temperature reaches the start-up temperature, the compressor and the first fan 30 are started. It is then determined whether the cooling rate is greater than the first threshold. If the cooling rate is greater than the first threshold, the second fan 40 is stopped. If the cooling rate is less than or equal to the first threshold, the second fan 40 is started. It is then determined whether the cooling rate exceeds the second threshold. If the cooling rate does not exceed the second threshold, the second fan 40 is upgraded to a higher speed. It is then determined whether the cooling rate exceeds the third threshold. If the cooling rate does not exceed the third threshold, the defrosting logic is executed.

[0086] The control method for the storage device provided in this application obtains the temperature measurement value and cooling rate of the compartment. Based on the temperature measurement value, cooling rate, preset start-up temperature and shutdown temperature, the method controls the start-up and shutdown of the compressor, the first fan and the second fan. According to the cooling rate in the compartment, the start-up, shutdown and speed of the compressor, the first fan and the second fan are adjusted in a stepwise manner, realizing the coupled control of air volume by the dual fans and the compressor, improving the cooling efficiency and reducing the overall energy consumption of the machine.

[0087] In one embodiment of this application, controlling the start and stop of the compressor, the first fan, and the second fan based on the measured temperature value, the cooling rate, and the preset start-up and stop-down temperatures includes:

[0088] When the temperature measurement value of the chamber reaches the start-up temperature, the compressor and the first fan are controlled to start.

[0089] If the cooling rate exceeds the first threshold, the second fan is controlled to stop working;

[0090] Determine whether the measured temperature value has reached a first temperature. When the measured temperature value reaches the first temperature, control the compressor to stop, the first fan to stop, and the second fan to start. The first temperature is the sum of the shutdown point temperature and the first temperature value.

[0091] When the measured temperature reaches the shutdown point temperature, the second fan is controlled to stop.

[0092] It is easy to understand that the controller acquires the temperature measurement value of the room temperature sensor in real time, and controls the compressor and the first fan to start when the room temperature measurement value reaches the compressor start-up temperature.

[0093] After the compressor and the first fan have been running for a period of time t1, the controller obtains the cooling rate v1 of the room during the time period t1 and determines whether the cooling rate v1 is greater than the first threshold. The first threshold is the minimum cooling rate value that meets the cooling demand of the room. If the cooling rate v1 is greater than the first threshold, it means that the cooling rate can meet the cooling demand of the room at this time, and the second fan is controlled to stop working.

[0094] Furthermore, during the operation of the compressor and the first fan, the temperature sensor acquires the temperature measurement value of the chamber in real time and determines whether the temperature measurement value has reached the first temperature. The first temperature is the sum of the compressor shutdown point temperature and the first temperature value. For example, if the compressor shutdown point temperature is T1 and the first temperature value is 0.5 degrees Celsius, then the first temperature is T1 + 0.5 degrees Celsius. When the temperature measurement value reaches the first temperature T1 + 0.5 degrees Celsius, it indicates that the temperature in the chamber is close to the compressor shutdown point temperature at this time, and more cold energy is deposited at the bottom of the evaporator, close to the position of the second fan.

[0095] The controller stops the compressor and the first fan, and starts the second fan. The second fan continues to cool the room by utilizing the remaining cooling capacity of the evaporator in the room.

[0096] Furthermore, during the operation of the second fan, the temperature sensor acquires the temperature measurement value of the room in real time, determines whether the temperature measurement value has reached the shutdown point temperature, and controls the second fan to stop when the temperature measurement value reaches the shutdown point temperature.

[0097] In the above technical solution, when the temperature measurement value reaches the start-up temperature, the compressor and the first fan are started. When the cooling rate is greater than the first threshold, the second fan is stopped. This can reduce unnecessary energy consumption. By stopping the compressor and the first fan and starting the second fan when the temperature measurement value reaches the first temperature, the remaining cold energy is fully utilized, improving the air supply efficiency and preservation effect of the storage equipment, and reducing the energy consumption and noise of the storage equipment.

[0098] In one embodiment of this application, after controlling the compressor and the first fan to start when the temperature measurement value of the compartment reaches the start-up temperature, the method further includes:

[0099] If the cooling rate is less than or equal to the first threshold, control the second fan to start;

[0100] Determine whether the cooling rate exceeds a second threshold, wherein the second threshold is greater than the first threshold;

[0101] If the cooling rate exceeds the second threshold, determine whether the temperature measurement value has reached the first temperature. If the temperature measurement value reaches the first temperature, control the compressor to stop and the first fan to stop.

[0102] When the measured temperature reaches the shutdown point temperature, the second fan is controlled to stop.

[0103] It is easy to understand that the controller acquires the temperature measurement value of the room temperature sensor in real time, and controls the compressor and the first fan to start when the room temperature measurement value reaches the compressor start-up temperature.

[0104] After the compressor and the first fan have been running for a period of time t1, the controller obtains the cooling rate v1 of the room during the time period t1 and determines whether the cooling rate v1 is greater than the first threshold. The first threshold is the minimum cooling rate value that meets the cooling demand of the room. If the cooling rate v1 is less than or equal to the first threshold, it means that the cooling rate cannot meet the cooling demand of the room at this time, and the second fan is controlled to start.

[0105] After the compressor, the first fan, and the second fan have been running for a period of time t2, the controller obtains the cooling rate v2 of the room during the time period t2 and determines whether the cooling rate v2 is greater than the second threshold. The second threshold is the minimum cooling rate value that meets the cooling requirements of the room when the first fan and the second fan are working at the same time. The second threshold is greater than the first threshold.

[0106] When the cooling rate v2 exceeds the second threshold, the temperature sensor acquires the temperature measurement value of the chamber in real time and determines whether the temperature measurement value has reached the first temperature. When the temperature measurement value reaches the first temperature, it means that the temperature in the chamber is close to the compressor shutdown point temperature at this time, and more cold energy is deposited at the bottom of the evaporator, close to the second fan. The compressor and the first fan are then stopped, while the second fan continues to run.

[0107] Furthermore, during the operation of the second fan, the temperature sensor acquires the temperature measurement value of the room in real time, determines whether the temperature measurement value has reached the shutdown point temperature, and controls the second fan to stop when the temperature measurement value reaches the shutdown point temperature.

[0108] In the above technical solution, when the cooling rate is less than or equal to the first threshold, the second fan is started, realizing adaptive control of the room temperature. The simultaneous operation of the first and second fans can reduce speed and temperature fluctuations, reduce noise, and improve refrigeration efficiency and preservation effect compared to the operation of a single fan alone.

[0109] In one embodiment of this application, after determining whether the cooling rate exceeds a second threshold, the method further includes:

[0110] If the cooling rate does not exceed the second threshold, control the second fan to operate at a higher speed;

[0111] Determine whether the cooling rate exceeds the third threshold;

[0112] If the cooling rate exceeds the third threshold, determine whether the temperature measurement value has reached the first temperature;

[0113] When the measured temperature reaches the first temperature, the compressor and the first fan are controlled to stop.

[0114] When the measured temperature reaches the shutdown point temperature, the second fan is controlled to stop.

[0115] It is easy to understand that after the compressor, the first fan and the second fan have been running for a period of time t2, the controller obtains the cooling rate v2 of the room during the time period t2 and determines whether the cooling rate v2 is greater than the second threshold. If the cooling rate does not exceed the second threshold, it means that the cooling rate cannot meet the cooling demand of the room at this time, and the controller controls the second fan to run at a higher speed. Running at a higher speed means increasing the speed or output power.

[0116] After the compressor, the first fan, and the upgraded second fan have been running for a period of time t3, the controller obtains the cooling rate v3 of the room during the time period t3 and determines whether the cooling rate v3 is greater than the third threshold. The third threshold is the minimum cooling rate value that meets the cooling requirements of the room when the first fan and the upgraded second fan are working at the same time. The third threshold is greater than the second threshold.

[0117] It should be noted that the embodiments of this application do not limit the number of times the second fan operates at higher speeds. For example, if the cooling rate of the room does not meet the minimum cooling rate value after the second fan has operated at a higher speed once, the second fan can continue to operate at a higher speed. In this case, the third threshold is the minimum cooling rate value that meets the cooling needs of the room when the first fan and the second fan after the last higher speed operation are working simultaneously. Gradually increasing the speed of the second fan can improve cooling efficiency and achieve energy-saving effects.

[0118] When the cooling rate v3 exceeds the third threshold, the temperature sensor acquires the temperature measurement value of the chamber in real time and determines whether the temperature measurement value has reached the first temperature. When the temperature measurement value reaches the first temperature, it means that the temperature in the chamber is close to the compressor shutdown point temperature. More cold energy is deposited at the bottom of the evaporator, close to the second fan. The compressor and the first fan are controlled to stop, while the second fan continues to run, which can improve the air supply efficiency.

[0119] Furthermore, during the operation of the second fan, the temperature sensor acquires the temperature measurement value of the room in real time, determines whether the temperature measurement value has reached the shutdown point temperature, and controls the second fan to stop when the temperature measurement value reaches the shutdown point temperature.

[0120] In the above technical solution, if the cooling rate does not exceed the second threshold, the second fan is controlled to operate at a higher speed. This allows for adaptive control of the room temperature based on actual cooling needs. Furthermore, the simultaneous operation of the first and second fans, compared to a single fan operating alone, can reduce fan speed and temperature fluctuations, decrease noise and overall energy consumption, and improve cooling efficiency and preservation effect.

[0121] In one embodiment of this application, after determining whether the temperature measurement value has reached a first temperature, the method further includes:

[0122] If the measured temperature does not reach the first temperature, the compressor is controlled to run at low speed until the measured temperature reaches the first temperature, at which point the compressor and the first fan are controlled to stop.

[0123] When the measured temperature reaches the shutdown point temperature, the second fan is controlled to stop.

[0124] It is easy to understand that if the temperature measurement value has not reached the first temperature, it means that the indoor temperature is still some distance away from the compressor shutdown point temperature and cooling is still required. The compressor is controlled to run at low speed until the temperature sensor detects that the temperature measurement value has reached the first temperature. Then, the compressor and the first fan are controlled to stop, while the second fan continues to run.

[0125] Furthermore, during the operation of the second fan, the temperature sensor acquires the temperature measurement value of the room in real time, determines whether the temperature measurement value has reached the shutdown point temperature, and controls the second fan to stop when the temperature measurement value reaches the shutdown point temperature.

[0126] In the above technical solution, when the temperature measurement value has not reached the first temperature, the compressor is controlled to run at a low speed, which can continue to cool the food while reducing energy consumption. This achieves adaptive control of the room temperature. Moreover, when the compressor runs at a low speed, the air speed is lower and the temperature fluctuation range is smaller, which reduces the possibility of high air speed blowing directly on the food and improves energy efficiency and preservation effect.

[0127] In one embodiment of this application, after determining whether the cooling rate exceeds a third threshold, the method further includes:

[0128] If the cooling rate does not exceed the third threshold, the defrosting judgment logic is executed.

[0129] It is easy to understand that after the compressor, the first fan, and the upgraded second fan have been running for a period of time t3, the controller obtains the cooling rate v3 of the compartment during the time period t3 and determines whether the cooling rate v3 is greater than the third threshold. If the cooling rate does not exceed the third threshold, it means that the evaporator may be too thickly iced and the defrosting judgment logic needs to be executed.

[0130] For example, the defrosting judgment logic can be to determine whether the frost layer thickness or frost amount has reached a preset value. If the frost layer thickness or frost amount has reached the preset value, the defrosting operation is performed.

[0131] In the above technical solution, if the cooling rate does not exceed the third threshold, the defrosting judgment logic is executed, which can perform the defrosting operation in a timely manner, improve the cooling efficiency, and reduce unnecessary overall energy consumption.

[0132] In one embodiment of this application, controlling the start and stop of the compressor, the first fan, and the second fan based on the measured temperature value, the cooling rate, and the preset start-up and stop-down temperatures includes:

[0133] If the measured temperature value does not reach the power-on temperature, determine whether the measured temperature value is greater than the set temperature.

[0134] When the measured temperature value is greater than the set temperature, the compressor is not started, and the first fan or the second fan is started.

[0135] Determine whether the measured temperature value has reached the shutdown point temperature;

[0136] When the measured temperature reaches the shutdown point temperature, the first fan or the second fan is turned off; or...

[0137] If the measured temperature does not reach the shutdown point temperature, the compressor is controlled to run at low speed until the measured temperature reaches the first temperature, at which point the compressor is controlled to stop, the first fan is stopped, and the second fan is started.

[0138] When the measured temperature reaches the shutdown point temperature, the second fan is turned off.

[0139] It is easy to understand that the controller acquires the temperature measurement value of the temperature sensor in the room in real time. If it detects that the temperature measurement value of the room has not reached the start-up temperature of the compressor, it determines whether the temperature measurement value is greater than the set temperature.

[0140] It should be noted that the set temperature should be lower than the compressor's start-up temperature but higher than the compressor's shutdown temperature. The set temperature can be adjusted according to the actual situation and scenario.

[0141] When the measured temperature is higher than the set temperature, the compressor is not started, but the first or second fan is started to reduce energy consumption. The controller obtains the temperature measurement value of the room temperature sensor in real time and determines whether the measured temperature has reached the shutdown point temperature. When the measured temperature reaches the shutdown point temperature, the first or second fan is turned off.

[0142] If the measured temperature does not reach the shutdown point, the compressor is controlled to run at low speed until the measured temperature reaches the first temperature. Then, the compressor and the first fan are stopped, and the second fan is started. When the measured temperature reaches the shutdown point, the second fan is turned off. The compressor running at low speed can ensure the operation of the refrigeration system. While ensuring that the cooling capacity is not wasted, energy saving and noise reduction can be achieved.

Figure 3 As shown, the control method of the storage device includes steps 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360 and 370.

[0147] Step 240: Determine if the measured temperature has reached the shutdown temperature.

[0148] Step 250: When the temperature measurement value reaches the shutdown point temperature, turn off the first fan or the second fan;

[0149] Step 260: If the temperature measurement value has not reached the shutdown point temperature, control the compressor to run at low speed;

[0150] Step 270: Determine whether the temperature measurement value has reached the first temperature;

[0151] Step 280: When the temperature measurement value reaches the first temperature, control the compressor to stop, the first fan to stop, and the second fan to start;

[0153] Step 300: If the temperature measurement value reaches the start-up temperature, control the compressor and the first fan to start;

[0154] Step 310: Determine if the cooling rate is greater than the first threshold.

[0155] Step 320: If the cooling rate is greater than the first threshold, control the second fan to stop working and jump to step 270;

[0156] Step 330: If the cooling rate is less than or equal to the first threshold, control the second fan to start;

[0157] Step 340: Determine whether the cooling rate exceeds the second threshold.

[0158] Step 350: If the cooling rate does not exceed the second threshold, control the second fan to operate at a higher speed;

[0159] It should be noted that if the cooling rate exceeds the second threshold, proceed to step 270;

[0160] Step 360: Determine if the cooling rate exceeds the third threshold;

[0161] It should be noted that if the cooling rate exceeds the third threshold, proceed to step 270;

[0162] Step 370: If the cooling rate does not exceed the third threshold, execute the defrosting judgment logic.

[0163] In the above technical solution, if the temperature measurement value does not reach the start-up temperature, it is determined whether the temperature measurement value is greater than the set temperature; if the temperature measurement value is greater than the set temperature, the start and stop of the compressor, the first fan and the second fan are controlled to achieve a short-term cooling and temperature reduction, so that the temperature in the room reaches the compressor shutdown temperature, thereby improving the cooling efficiency and reducing the overall energy consumption of the unit.
