Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment technology, and more specifically, relates to a control method, apparatus, readable storage medium, and refrigeration equipment for refrigeration equipment. Background Technology

[0002] The refrigerator compartment of a frost-free refrigerator is cooled by cold air from a refrigeration evaporator or a freezing evaporator, and the cooling of the refrigerator compartment is controlled by a refrigeration temperature sensor.

[0003] In related technologies, air-cooled refrigerators use a side-discharge cooling duct. When the refrigerator is full, the food piled up in the refrigerator compartment will block both sides of the duct, causing the path of forward airflow to be blocked. Air can only be sent towards the return air vent. Since the sensor is located between the air supply vent and the return air vent, the sensor is very likely to be cooled before the food. Therefore, it will reach the shutdown point earlier. That is, although it is controlled normally according to the set start and stop points, the food in the full refrigerator compartment is not able to be cooled and the temperature remains high. As a result, the refrigerator compartment has poor preservation effect on food when it is full. Summary of the Invention

[0004] This application aims to solve the technical problem that the cold storage compartment has poor preservation effect on food when fully loaded, which exists in the prior art or related technologies.

[0005] Therefore, the first aspect of this application proposes a control method for a refrigeration device.

[0006] The second aspect of this application proposes a control device for a refrigeration equipment.

[0007] The third aspect of this application proposes a control device for a refrigeration equipment.

[0008] The fourth aspect of this application proposes a readable storage medium.

[0009] The fifth aspect of this application proposes a refrigeration device.

[0010] In view of this, a control method for a refrigeration device is proposed according to the first aspect of this application. The refrigeration device includes a refrigeration chamber, an air duct, and a temperature sensor. The air outlet of the air duct faces the side wall of the refrigeration chamber. The temperature sensor is located between the air outlet and the return air outlet of the air duct. The cold air output end of the refrigeration component is connected to the air outlet of the air duct. The temperature sensor is used to collect the chamber temperature of the refrigeration chamber. The control method for the refrigeration device includes: when the refrigeration component is controlled to operate according to the start-up and stop temperatures set at the current temperature, obtaining a first start-up duration and a first start-up rate of the refrigeration component; determining the refrigeration state of the refrigeration chamber based on the first start-up duration and the first start-up rate; reducing the start-up and stop temperatures when the refrigeration state of the refrigeration chamber is in a state of insufficient cooling capacity; and controlling the operation of the refrigeration component based on the chamber temperature and the reduced start-up and stop temperatures.

[0011] In this technical solution, the refrigeration equipment is equipped with a refrigeration chamber, and the refrigeration chamber is equipped with an air duct and a temperature sensor. The air duct is located on the rear side wall of the refrigeration chamber, and the air outlet of the air duct faces the left and right side walls of the refrigeration chamber. The temperature sensor is also located in the refrigeration chamber, between the air outlet and the return air outlet of the air duct.

[0012] It should be noted that the start-up and stop temperatures can be set by the user according to actual needs during the operation of the refrigeration equipment. Specifically, the user sets the current set temperature of the room, and the refrigeration equipment can automatically match the corresponding start-up and stop temperatures. The refrigeration equipment controls the operation of the refrigeration components based on the currently set start-up and stop temperatures to cool the room.

[0013] In this technical solution, a refrigeration unit is used to transmit cold air into the refrigeration room through an air duct, thereby cooling the contents of the refrigeration room. During the cooling process, a temperature sensor continuously collects the room temperature. When the room temperature drops to the start-stop temperature, the refrigeration unit stops transmitting cold air; when the room temperature rises above the start-stop temperature, the refrigeration unit resumes transmitting cold air. Since the start-stop state of the refrigeration unit is controlled based on the room temperature and the start-stop temperature, the refrigeration unit switches between start-up and stop-down states. During this switching process, a first start-up duration and a first start-up rate are obtained.

[0014] Specifically, the refrigeration equipment records the first start-up time of the refrigeration component in the start-up state and the shutdown time of the refrigeration component in the shutdown state. Based on the first start-up time and shutdown time, the first start-up rate can be calculated, that is, the first start-up rate is the start-up rate of the refrigeration component when the refrigeration component is running according to the start-up and shutdown temperature control.

[0015] In this technical solution, when the refrigeration chamber is fully loaded, the temperature sensor is more likely to be cooled before the food, reaching the start-up and shutdown temperatures earlier. This means the initial start-up time and initial start-up rate will decrease compared to the no-load state. At this point, the refrigeration chamber is determined to be in a state of insufficient cooling capacity. Therefore, based on the obtained initial start-up time and initial start-up rate, it is possible to determine whether the refrigeration chamber is in a state of insufficient cooling capacity.

[0016] In this technical solution, when it is determined that the refrigeration chamber is in a fully loaded state, it is determined that the refrigeration chamber is in a state of insufficient cooling capacity. Therefore, it is determined that the refrigeration components cannot effectively cool the food in the refrigeration chamber according to the start-up and stop-down temperatures. Thus, it is necessary to update and obtain the reduced start-up and stop-down temperatures, and control the switching between the start-up and stop-down states of the refrigeration components based on the chamber temperature collected by the temperature sensor and the reduced start-up and stop-down temperatures.

[0017] In this application's technical solution, during the process of controlling the operation of the refrigeration components according to the start-up and stop-down temperatures of the refrigeration equipment, the system determines whether the refrigeration chamber is in a state of insufficient cooling capacity due to full load by acquiring the first start-up duration and the first start-up rate of the refrigeration components. If the refrigeration chamber is detected to be in a state of insufficient cooling capacity, the refrigeration equipment controls the operation of the refrigeration components according to a lower start-up and stop-down temperature than the original start-up and stop-down temperature set at the current temperature, thereby improving the refrigeration and preservation effect of the refrigeration components on the food in the refrigeration chamber under insufficient cooling capacity conditions.

[0018] In some technical solutions, optionally, the cooling status of the cooling room is determined based on the first start-up duration and the first start-up rate, including:

[0019] Based on the current ambient temperature and the set temperature, obtain a first duration threshold and a first operating rate threshold; if the first operating time is less than the first duration threshold, compare the numerical relationship between the first operating rate and the first operating rate threshold; if the first operating rate is less than the first operating rate threshold, determine that the cooling room is in a state of insufficient cooling capacity; if the first operating time is greater than or equal to the first duration threshold, determine that the cooling room is not in a state of insufficient cooling capacity; if the first operating rate is greater than or equal to the first operating rate threshold, determine that the cooling room is not in a state of insufficient cooling capacity.

[0020] In this technical solution, if the first start-up time is less than a first time threshold and the first start-up rate is less than a first start-up rate threshold, the cooling room is determined to be in a state of insufficient cooling capacity. The first time threshold and the first start-up rate threshold are related to the current ambient temperature and the set temperature, where the current ambient temperature is the current ambient temperature.

[0021] Specifically, the first duration threshold and the first operating rate threshold required to determine whether a cooling room is fully loaded differ depending on the operating conditions of the refrigeration equipment. Therefore, to determine whether a cooling room is fully loaded, it is necessary to obtain the corresponding first duration threshold and first operating rate threshold. After obtaining the first duration threshold and the first operating rate threshold, the first operating time is compared with the first duration threshold. If the first operating time is greater than or equal to the first duration threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity. If the first operating time is less than the first duration threshold, the first operating rate is further compared with the first operating rate threshold. If the first operating rate is greater than or equal to the first operating rate threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity; otherwise, it is determined that the cooling room is in a state of insufficient cooling capacity.

[0022] In the technical solution of this application, after obtaining the first start-up duration and the first start-up rate corresponding to the start-up and stop temperatures, a first duration threshold and a first start-up rate threshold matching the operating conditions are obtained. The start-up duration is compared with the first duration threshold and the first start-up rate is compared with the first start-up rate threshold in sequence. When it is detected that the first start-up duration is less than the first duration threshold and the first start-up rate is less than the first start-up rate, it is determined that the refrigeration room is in a state of insufficient cooling capacity, thereby improving the accuracy of detecting the state of insufficient cooling capacity.

[0023] In this technical solution, when the first start-up duration is detected to be greater than or equal to the first duration threshold, or the first start-up rate is greater than or equal to the first start-up rate threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity. At this time, the operation of the cooling components continues to be controlled according to the start-up and shutdown temperatures.

[0024] Specifically, in determining whether a cooling room is experiencing insufficient cooling capacity, the first step is to compare the initial operating time with a first time threshold. If the initial operating time is greater than or equal to the first time threshold, the cooling room is determined not to be experiencing insufficient cooling capacity, and there is no need to further compare the numerical relationship between the initial operating rate and the first operating rate threshold. If the initial operating time is less than the first time threshold, the numerical relationship between the initial operating rate and the first operating rate threshold is then compared. If the initial operating rate is greater than or equal to the first operating rate threshold, the cooling room is determined not to be experiencing insufficient cooling capacity.

[0025] In the technical solution of this application, when the first start-up duration is greater than or equal to the first duration threshold, or the first start-up rate is greater than or equal to the first start-up rate threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity, which further improves the accuracy of the determination of the state of the cooling room.

[0026] In some technical solutions, optionally, obtaining the first duration threshold and the first power-on rate threshold includes:

[0027] Obtain the ambient temperature of the environment where the refrigeration equipment is located, as well as the target temperature of the refrigeration room;

[0028] Based on the ambient temperature and the target temperature of the cooling room, determine the first duration threshold and the first operating rate threshold.

[0029] In this technical solution, the first duration threshold and the first start-up rate threshold are matched with the operating conditions of the refrigeration equipment, which include the ambient temperature of the environment and the target temperature of the refrigeration room.

[0030] Specifically, the refrigeration equipment includes an ambient temperature sensor, which collects the ambient temperature of the environment in which the refrigeration equipment is located. The refrigeration equipment can be adjusted to different operating levels, with different levels corresponding to different target temperatures in the refrigerated compartments.

[0031] It should be noted that the correspondence between the first duration threshold and the first operating rate threshold and the target temperature and ambient temperature range of the cooling room is stored in the cooling equipment or in the cloud server, so that after the cooling equipment collects the ambient temperature and determines the target temperature of the cooling room, it can determine the corresponding first duration threshold and first operating rate threshold according to the correspondence.

[0032] In the technical solution of this application, a first duration threshold and a first start-up rate threshold are set according to the ambient temperature of the environment where the refrigeration equipment is located and the target temperature of the refrigeration room set by the refrigeration equipment, thereby improving the accuracy of the criteria for judging the refrigeration status of the refrigeration room and further improving the accuracy of judging the refrigeration status of the refrigeration room.

[0033] In some technical solutions, optionally, when the cooling capacity of the cooling room is insufficient, the start-up and shutdown temperatures are lowered, including:

[0034] Obtain the preset temperature; reduce the start-up and shutdown temperatures based on the preset temperature to obtain the reduced start-up and shutdown temperatures.

[0035] In this technical solution, when it is determined that the cooling room is in a state of insufficient cooling capacity, the initial start-up and shutdown temperatures are lowered according to the preset temperature, that is, the start-up and shutdown temperatures are lowered by setting the preset temperature, thereby obtaining the lowered start-up and shutdown temperatures.

[0036] It should be noted that if insufficient cooling capacity is detected in the cooling room, the preset temperature is lowered from the current start / stop temperature to obtain a lowered start / stop temperature, and the cooling components are controlled according to the lowered start / stop temperature. If insufficient cooling capacity is detected again while the cooling components are being controlled according to the lowered start / stop temperature, the preset temperature is lowered again based on the lowered start / stop temperature until the cooling room is no longer in a state of insufficient cooling capacity.

[0037] In the technical solution of this application, the current start-up and shutdown temperatures are adjusted according to the preset temperature, which can avoid excessive adjustment of the start-up and shutdown temperatures, resulting in excessively low indoor temperatures in the refrigeration room.

[0038] In some technical solutions, optionally, after controlling the operation of the refrigeration components based on the room temperature and the reduced start-up and shutdown temperatures, the control method for the refrigeration equipment also includes:

[0039] The second start-up duration of the timing refrigeration unit is determined by controlling the operation of the refrigeration unit based on the room temperature and the reduced start-up and shutdown temperatures. When the second start-up duration reaches the second duration threshold, the adjustment parameters of the reduced start-up and shutdown temperatures are obtained. If the adjustment parameters meet the target conditions, the process returns to the step of obtaining the first start-up duration and the first start-up rate of the refrigeration unit.

[0040] In this technical solution, after obtaining the reduced start-up and shutdown temperatures, and controlling the operation of the refrigeration components according to the reduced start-up and shutdown temperatures and the collected room temperature, timing begins. When the timing reaches the second duration threshold, it is determined that the control of the refrigeration room according to the reduced start-up and shutdown temperatures has reached a stable state. At this point, the process can return to the step of obtaining the first start-up duration and the first start-up rate of the refrigeration components, and based on the first start-up duration and the first start-up rate, it can be determined again whether the refrigeration room is in a state of insufficient cooling capacity.

[0041] Specifically, the reduced start-up and shutdown temperature is the temperature obtained by subtracting a preset temperature from the current start-up and shutdown temperature. When the refrigeration components are controlled according to the reduced start-up and shutdown temperature to reach the second duration threshold, it is determined that the state inside the refrigeration room has stabilized and the adjusted parameters meet the target conditions. The system then returns to obtain the first start-up duration and the first start-up rate to re-detect the refrigeration status inside the refrigeration room. If the refrigeration room is still found to have insufficient cooling capacity, the reduced start-up and shutdown temperature is lowered again according to the preset temperature. This cycle continues until the refrigeration room is no longer found to have insufficient cooling capacity.

[0042] It should be noted that before returning to retrieve the first boot duration and the first boot rate, it is necessary to determine whether the adjustment parameters of the start-up and shutdown temperatures meet the target conditions, that is, to determine whether there are problems such as over-adjustment of the start-up and shutdown temperatures.

[0043] In the technical solution of this application, after the refrigeration equipment operates for a second time threshold according to the reduced start-up and shutdown temperature, it returns to the execution of the detection step to check whether the refrigeration equipment is in a state of insufficient cooling capacity. By cyclically performing the detection and adjustment steps, the cooling capacity of the refrigeration room is ensured to be sufficient, avoiding the problem of insufficient cooling capacity caused by the refrigeration room being fully loaded.

[0044] In some technical solutions, the adjustment parameters optionally include: total temperature adjustment value and number of temperature adjustments;

[0045] The target conditions include at least one of the following: the total temperature adjustment value is less than or equal to the total adjustment value threshold, and the number of temperature adjustments is less than or equal to the number threshold.

[0046] In this technical solution, the adjustment parameters include the total temperature adjustment value for adjusting the start-up and shutdown temperatures, and the number of adjustments made to the start-up and shutdown temperatures. When the cooling capacity of the refrigeration room is insufficient, the process of detecting and lowering the start-up and shutdown temperatures is repeated. Therefore, the start-up and shutdown temperatures may be adjusted multiple times. Thus, at least one of the total temperature adjustment value and the number of temperature adjustments is obtained, and the corresponding target conditions are judged. If the target conditions are met, it is determined that the start-up and shutdown temperatures have not been over-adjusted, and the process continues to check for insufficient cooling capacity in the refrigeration room. Otherwise, the process stops, and the step of checking for insufficient cooling capacity in the refrigeration room is stopped, thus avoiding excessive adjustment of the start-up and shutdown temperatures.

[0047] Specifically, the adjustment parameter is the total temperature adjustment value. If the total temperature adjustment value is less than or equal to the total adjustment value threshold, the process continues to return to the step of checking whether there is insufficient cooling capacity in the refrigeration room; otherwise, the process stops returning to the step of checking whether there is insufficient cooling capacity in the refrigeration room.

[0048] In the technical solution of this application, during the process of cyclically executing the steps of detecting whether there is insufficient cooling capacity and adjusting the start-stop temperature, the number of times the start-stop temperature is adjusted and / or the total value of the adjusted temperature is obtained, and it is determined whether the adjustment of the start-stop temperature is excessive. If it is detected that the adjustment of the start-stop temperature is not excessive, the process returns to the step of determining whether the cooling room has insufficient cooling capacity; otherwise, the current start-stop temperature is maintained and the system continues to operate.

[0049] In some technical solutions, optionally, after determining the cooling status of the cooling room based on the first start-up duration and first start-up rate of the refrigeration components, the control method for the refrigeration equipment further includes:

[0050] If the cooling state of the cooling room is not in a state of insufficient cooling capacity and the cooling equipment completes the target action, the timer is set for the duration of the action completion; if the duration of the action completion reaches the third duration threshold, the second start-up rate of the cooling components is obtained; if the second start-up rate is greater than or equal to the second start-up rate threshold, the operation of the cooling components is controlled according to the room temperature and the initial start-up and shutdown temperature, wherein the initial start-up and shutdown temperature is the start-up and shutdown temperature before the reduced start-up and shutdown temperature is determined.

[0051] In this technical solution, when it is detected that the cooling room is not in a state of insufficient cooling, and the time taken for the cooling equipment to complete the target action reaches the third time threshold, the second start-up rate of the cooling component at this time is obtained. That is, the second start-up rate is the start-up rate after the cooling equipment has completed the target action.

[0052] Specifically, when it is determined that the cooling capacity of the cooling room is sufficient based on the start-up time or the first start-up rate, if the cooling equipment has performed the target action, after the third time threshold of the target action is completed, the current second start-up rate is obtained, and the second start-up rate is compared with the second start-up rate threshold. If the comparison shows that the second start-up rate is greater than or equal to the second start-up rate threshold, the cooling components are controlled to operate according to the initial stop temperature before adjustment.

[0053] Among them, the second start-up rate threshold is greater than the first start-up rate threshold. When the second start-up rate is greater than the second start-up rate threshold, it is determined that the cooling capacity of the cooling room is excessive. Therefore, the reduced start-up and shutdown temperature needs to be restored to the initial start-up and shutdown temperature.

[0054] It should be noted that the second operating rate threshold is related to the operating conditions of the refrigeration equipment. Specifically, the second operating rate threshold is determined based on the ambient temperature and the target temperature of the refrigeration room set by the user.

[0055] In the technical solution of this application, when it is determined by the first start-up rate or start-up duration that the refrigeration room is not in a state of insufficient cooling capacity, after the refrigeration equipment performs the target action, the second start-up rate is used to detect whether there is excess cooling capacity in the refrigeration room. When it is detected that there is excess cooling capacity when the refrigeration components are operated according to the reduced shutdown control, the temperature is adjusted back to the initial start-up and shutdown temperature to control the refrigeration components, thereby ensuring the preservation effect of the food in the refrigeration room.

[0056] In some technical solutions, the target action may optionally include at least one of the following: adjusting the cooling temperature of the cooling room, opening and closing the door of the cooling room, and the refrigeration equipment completing the defrosting action.

[0057] In the technical solution of this application, adjusting the cooling temperature of the cooling room, opening and closing the door of the cooling room, and completing the defrosting action of the cooling equipment will all affect the cooling status of the cooling room. Therefore, after the third time threshold is reached after the target action is completed, the second start-up rate is obtained, and the start-up and shutdown temperatures are further adjusted based on the obtained second start-up rate, so as to avoid the impact on the accuracy of the cooling status detection of the cooling room after the cooling equipment performs the target action.

[0058] In some technical solutions, optionally, before determining the cooling status of the cooling room based on the first start-up duration and the first start-up rate of the cooling components, the control method of the cooling equipment further includes: obtaining the shutdown duration of the cooling components; and determining the first start-up rate as the ratio between the first start-up duration and the sum of durations, wherein the sum of durations is the sum of the shutdown duration and the first start-up duration.

[0059] In the technical solution of this application, the refrigeration equipment records the first start-up time of the refrigeration component in the start-up state and the shutdown time of the refrigeration component in the shutdown state. The first start-up rate can be calculated based on the first start-up time and the shutdown time, that is, the first start-up rate is the start-up rate of the refrigeration component when the refrigeration component is running according to the start-up and shutdown temperature control.

[0060] According to a second aspect of this application, a control device for a refrigeration equipment is provided. The refrigeration equipment includes a refrigeration chamber, an air duct, and a temperature sensor. The air outlet of the air duct faces the side wall of the refrigeration chamber. The temperature sensor is located between the air outlet and the return air outlet of the air duct. The output end of the refrigeration component is connected to the air outlet of the air duct. The temperature sensor is used to collect the chamber temperature of the refrigeration chamber. The control device for the refrigeration equipment includes: an acquisition module, used to acquire a first start-up duration and a first start-up rate of the refrigeration component when the refrigeration component is controlled to operate according to the start-up and stop-up temperatures set at the current temperature; a determination module, used to determine the refrigeration state of the refrigeration chamber based on the first start-up duration and the first start-up rate; an adjustment module, used to reduce the start-up and stop-up temperatures when the refrigeration state of the refrigeration chamber is in a state of insufficient cooling capacity; and a control module, used to control the operation of the refrigeration component based on the chamber temperature and the reduced start-up and stop-up temperatures.

[0061] In this application's technical solution, during the process of controlling the operation of the refrigeration components according to the start-up and stop-down temperatures of the refrigeration equipment, the system determines whether the refrigeration chamber is in a state of insufficient cooling capacity due to full load by acquiring the first start-up duration and the first start-up rate of the refrigeration components. If the refrigeration chamber is detected to be in a state of insufficient cooling capacity, the refrigeration equipment controls the operation of the refrigeration components according to a lower start-up and stop-down temperature than the original start-up and stop-down temperature set at the current temperature, thereby improving the refrigeration and preservation effect of the refrigeration components on the food in the refrigeration chamber under insufficient cooling capacity conditions.

[0062] According to a third aspect of this application, a control device for a refrigeration device is provided. The control device includes a processor and a memory, the memory storing a program or instructions. When executed by the processor, the program or instructions implement the steps of the control method for the refrigeration device as described in any of the above-described technical solutions. Therefore, this control device for the refrigeration device possesses all the beneficial effects of the control method for the refrigeration device in any of the above-described technical solutions, which will not be elaborated further here.

[0063] According to the fourth aspect of this application, a readable storage medium is provided on which a program or instructions are stored. When the program or instructions are executed by a processor, they implement the steps of the control method for the refrigeration equipment as described in any of the above technical solutions, and thus have all the beneficial technical effects of the control method for the refrigeration equipment as described in any of the above technical solutions.

[0064] According to the fifth aspect of this application, a refrigeration device is provided, comprising: a control device for the refrigeration device as described in any of the above technical solutions, and / or a readable storage medium as described in any of the above technical solutions, thus having all the beneficial technical effects of the control device for the refrigeration device as described in any of the above technical solutions, and / or the readable storage medium as described in any of the above technical solutions, which will not be elaborated further here.

[0079] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, these embodiments and the features described herein can be combined with each other.

[0080] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0081] The following reference Figures 1 to 10 This application describes a control method for a refrigeration device, a control device for a refrigeration device, a readable storage medium, and a refrigeration device according to some embodiments of the present application.

[0082] According to one embodiment of this application, Figure 1 This illustration shows one of the flowcharts of a control method for a refrigeration device provided in some embodiments of this application, such as... Figure 1 As shown, a control method for a refrigeration device is proposed. The refrigeration device includes a refrigeration chamber, an air duct, and a temperature sensor. The air outlet of the air duct faces the side wall of the refrigeration chamber. The temperature sensor is located between the air outlet and the return air outlet of the air duct. The cold air output terminal of the refrigeration component is connected to the air outlet of the air duct. The temperature sensor is used to collect the chamber temperature of the refrigeration chamber. The control method for the refrigeration device includes:

[0083] Step 102: Under the condition that the operation of the refrigeration component is controlled according to the start-up and stop-up temperature of the current set temperature, obtain the first start-up duration and the first start-up rate of the refrigeration component.

[0084] In this embodiment, a refrigeration chamber is provided inside the refrigeration equipment. An air duct and a temperature sensor are provided inside the refrigeration chamber. The air duct is located on the rear side wall of the refrigeration chamber, and the air outlet of the air duct faces the left and right side walls of the refrigeration chamber. The temperature sensor is also located inside the refrigeration chamber, between the air outlet and the return air outlet of the air duct.

[0085] It should be noted that the start-up and stop temperatures can be set by the user according to actual needs during the operation of the refrigeration equipment. Specifically, the user sets the current set temperature of the room, and the refrigeration equipment can automatically match the corresponding start-up and stop temperatures. The refrigeration equipment controls the operation of the refrigeration components based on the currently set start-up and stop temperatures to cool the room.

[0086] For example, the start-up and shutdown temperatures can be a temperature range, where the highest value of the temperature range is the start-up temperature and the lowest value of the temperature range is the shutdown temperature.

[0087] Table 1 shows the relationship between the current set temperature and the start-up and shutdown temperatures, as detailed below:

[0088] Table 1

[0089]

[0090] Figure 2 The following are schematic diagrams illustrating the structure of a refrigeration device 200 provided in some embodiments of this application, such as... Figure 2 As shown, the refrigeration equipment 200 is a refrigerator, the refrigeration compartment 202 is the refrigerator's cold storage compartment, the air duct 204 is located between the rear side wall of the cold storage compartment and the glass partition 214, the air outlet 208 is located on the left and right side walls of the air duct 204, the return air inlet 210 is located at the bottom of the refrigeration compartment 202, and the temperature sensor 206 is located between the air outlet 208 and the return air inlet 210. The refrigeration assembly 212 is located inside the refrigeration equipment 200. The refrigeration assembly 212 includes an evaporator, a fan, and a damper. One end of the air duct 204 is positioned opposite the evaporator. The cooling capacity generated by the evaporator during operation cools the air driven by the fan, forming cold air. After the damper is opened, the cold air is transmitted to the refrigeration compartment 202 through the air duct 204.

[0091] In this embodiment, the refrigeration component is used to transmit cold air into the refrigeration room through an air duct, thereby cooling the contents of the refrigeration room. During the cooling process, a temperature sensor continuously collects the room temperature. When the room temperature drops to the start-stop temperature, the refrigeration component stops transmitting cold air into the refrigeration room; when the room temperature rises above the start-stop temperature, the refrigeration component resumes transmitting cold air into the refrigeration room. Since the start-stop state of the refrigeration component is controlled based on the room temperature and the start-stop temperature, the refrigeration component switches between start-up and stop-down states. During this switching process, a first start-up duration and a first start-up rate are obtained.

[0092] Specifically, the refrigeration equipment records the first start-up time of the refrigeration component in the start-up state and the shutdown time of the refrigeration component in the shutdown state. Based on the first start-up time and shutdown time, the first start-up rate can be calculated, that is, the first start-up rate is the start-up rate of the refrigeration component when the refrigeration component is running according to the start-up and shutdown temperature control.

[0093] Step 104: Determine the cooling status of the cooling room based on the first start-up duration and the first start-up rate;

[0094] In this embodiment, when the refrigeration chamber is fully loaded, the temperature sensor is more likely to be cooled before the food, reaching the start-stop temperature earlier. This means the first start-up time and first start-up rate will decrease compared to the no-load state. At this point, it is determined that the refrigeration chamber is in a state of insufficient cooling capacity. Therefore, based on the obtained first start-up time and first start-up rate, it is possible to determine whether the refrigeration chamber is in a state of insufficient cooling capacity.

[0095] Figure 3 This illustration shows one of the schematic diagrams of cold air flow in an unloaded cooling room provided in some embodiments of this application. Figure 4 This is shown as a second schematic diagram of cold air flow in an unloaded state in some embodiments of this application, such as... Figure 2 and Figure 3 As shown, the cold air output from the air outlet of the air duct flows to the left and right inner walls of the cooling room. After the cold air comes into contact with the left and right inner walls of the cooling room, the flow direction of the cold air changes and flows to the front wall of the cooling room, and finally flows towards the return air vent at the bottom of the cooling room. Arrow A indicates the direction of cold air flow.

[0096] Figure 5 This illustration shows one of the schematic diagrams of cold air flow in a fully loaded refrigeration room provided in some embodiments of this application. Figure 6 This is shown as a second schematic diagram of cold air flow in a fully loaded refrigeration room according to some embodiments of this application, such as... Figure 5and Figure 6 As shown, when the refrigeration room is fully loaded, the airflow path from the left and right inner walls to the front walls is blocked by the contents, and air can only be supplied to the return air vent at the bottom of the refrigeration room. At this time, the refrigeration room may be in a state of insufficient cooling capacity. Arrow B indicates the direction of airflow.

[0097] For example, when the refrigeration room is fully loaded, the maximum temperature inside the refrigeration room can rise by 4°C-6°C compared to when it is empty, making it impossible for the food to be cooled down to achieve a preservation effect.

[0098] Step 106: When the cooling capacity of the cooling room is insufficient, reduce the start-up and shutdown temperature.

[0099] Step 108: Control the operation of the refrigeration components based on the room temperature and the reduced start-up and shutdown temperatures.

[0100] In this embodiment, when it is determined that the refrigeration chamber is in a fully loaded state, it is determined that the refrigeration chamber is in a state of insufficient cooling capacity. Therefore, it is determined that the refrigeration component cannot effectively cool the food in the refrigeration chamber according to the start-up and stop-down temperatures. Thus, it is necessary to update and obtain the reduced start-up and stop-down temperatures, and control the switching between the start-up and stop-down states of the refrigeration component based on the chamber temperature collected by the temperature sensor and the reduced start-up and stop-down temperatures.

[0101] For example, Table 2 shows the operating rate and operating duration of the refrigeration room under full load and no load conditions.

[0102] Table 2

[0103]

[0104]

[0105] As shown in Table 2, when the refrigeration room is fully loaded, the temperature is high, and the operating rate and operating time are low.

[0106] Specifically, if the cooling room is under insufficient cooling capacity, controlling the operation of the refrigeration components according to the start-stop temperature will cause the refrigeration components to shut down prematurely. Therefore, updating the start-stop temperature to a lower, reduced start-stop temperature will allow the refrigeration components to run for a longer period of time, thereby achieving the desired cooling effect on the food in the cooling room.

[0107] For example, the reduced start-up temperature = start-up temperature - 2℃, and the reduced shutdown temperature = shutdown temperature - 2℃.

[0108] In this embodiment, during the process of controlling the operation of the refrigeration components according to the start-up and stop-down temperatures of the refrigeration equipment, the first start-up duration and first start-up rate of the refrigeration components are obtained to determine whether the refrigeration chamber is in a state of insufficient cooling capacity due to full load. If the refrigeration chamber is detected to be in a state of insufficient cooling capacity, the refrigeration equipment controls the operation of the refrigeration components according to a lower start-up and stop-down temperature than the original start-up and stop-down temperature set at the current temperature, thereby improving the refrigeration and preservation effect of the refrigeration components on the food in the refrigeration chamber under the state of insufficient cooling capacity.

[0109] In some embodiments, optionally, the cooling status of the cooling room is determined based on a first operating duration and a first operating rate, including:

[0110] Based on the current ambient temperature and the set temperature, obtain a first duration threshold and a first operating rate threshold; if the first operating time is less than the first duration threshold, compare the numerical relationship between the first operating rate and the first operating rate threshold; if the first operating rate is less than the first operating rate threshold, determine that the cooling room is in a state of insufficient cooling capacity; if the first operating time is greater than or equal to the first duration threshold, determine that the cooling room is not in a state of insufficient cooling capacity; if the first operating rate is greater than or equal to the first operating rate threshold, determine that the cooling room is not in a state of insufficient cooling capacity.

[0111] In this embodiment, if the first operating time is less than a first operating time threshold and the first operating rate is less than a first operating rate threshold, the cooling room is determined to be in a state of insufficient cooling capacity. The first operating time threshold and the first operating rate threshold are related to the current ambient temperature and the set temperature, where the current ambient temperature is the current ambient temperature.

[0112] Specifically, the first duration threshold and the first operating rate threshold required to determine whether a cooling room is fully loaded differ depending on the operating conditions of the refrigeration equipment. Therefore, to determine whether a cooling room is fully loaded, it is necessary to obtain the corresponding first duration threshold and first operating rate threshold. After obtaining the first duration threshold and the first operating rate threshold, the first operating time is compared with the first duration threshold. If the first operating time is greater than or equal to the first duration threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity. If the first operating time is less than the first duration threshold, the first operating rate is further compared with the first operating rate threshold. If the first operating rate is greater than or equal to the first operating rate threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity; otherwise, it is determined that the cooling room is in a state of insufficient cooling capacity.

[0113] For example, the first duration threshold ranges from 5 minutes to 20 minutes.

[0114] For example, the first power-on rate threshold ranges from 10% to 40%.

[0115] In this embodiment, after obtaining the first start-up duration and the first start-up rate corresponding to the start-up and stop temperatures, a first duration threshold and a first start-up rate threshold matching the operating conditions are obtained. The start duration is compared with the first duration threshold and the first start-up rate is compared with the first start-up rate threshold in sequence. When it is detected that the first start-up duration is less than the first duration threshold and the first start-up rate is less than the first start-up rate, it is determined that the cooling room is in a state of insufficient cooling capacity, thereby improving the accuracy of detecting the state of insufficient cooling capacity.

[0116] In this embodiment, when the first start-up duration is detected to be greater than or equal to the first duration threshold, or the first start-up rate is greater than or equal to the first start-up rate threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity. At this time, the operation of the cooling components continues to be controlled according to the start-up and shutdown temperatures.

[0117] Specifically, in determining whether a cooling room is experiencing insufficient cooling capacity, the first step is to compare the initial operating time with a first time threshold. If the initial operating time is greater than or equal to the first time threshold, the cooling room is determined not to be experiencing insufficient cooling capacity, and there is no need to further compare the numerical relationship between the initial operating rate and the first operating rate threshold. If the initial operating time is less than the first time threshold, the numerical relationship between the initial operating rate and the first operating rate threshold is then compared. If the initial operating rate is greater than or equal to the first operating rate threshold, the cooling room is determined not to be experiencing insufficient cooling capacity.

[0118] In this embodiment of the application, when the first power-on duration is greater than or equal to the first duration threshold, or the first power-on rate is greater than or equal to the first power-on rate threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity, which further improves the accuracy of the determination of the state of the cooling room.

[0119] In some embodiments, optionally, obtaining the first duration threshold and the first power-on rate threshold includes:

[0120] Obtain the ambient temperature of the environment where the refrigeration equipment is located, as well as the target temperature of the refrigeration room;

[0121] Based on the ambient temperature and the target temperature of the cooling room, determine the first duration threshold and the first operating rate threshold.

[0122] In this embodiment, the first duration threshold and the first start-up rate threshold are matched with the operating conditions of the refrigeration equipment, which include the ambient temperature of the environment and the target temperature of the refrigeration room.

[0123] Specifically, the refrigeration equipment includes an ambient temperature sensor, which collects the ambient temperature of the environment in which the refrigeration equipment is located. The refrigeration equipment can be adjusted to different operating levels, with different levels corresponding to different target temperatures in the refrigerated compartments.

[0124] It should be noted that the correspondence between the first duration threshold and the first operating rate threshold and the target temperature and ambient temperature range of the cooling room is stored in the cooling equipment or in the cloud server, so that after the cooling equipment collects the ambient temperature and determines the target temperature of the cooling room, it can determine the corresponding first duration threshold and first operating rate threshold according to the correspondence.

[0125] For example, the correspondence between the first duration threshold and the first operating rate threshold and the target temperature and ambient temperature range of the cooling room is shown in Table 3 below:

[0126] Table 3

[0127]

[0128]

[0129] In this embodiment, a first duration threshold and a first start-up rate threshold are set according to the ambient temperature of the environment where the refrigeration equipment is located and the target temperature of the refrigeration room where the refrigeration equipment is set, thereby improving the accuracy of the criteria for judging the refrigeration status of the refrigeration room and further improving the accuracy of judging the refrigeration status of the refrigeration room.

[0130] In some embodiments, optionally, when the cooling state of the cooling room is in a state of insufficient cooling capacity, reducing the start-up and shutdown temperature includes:

[0131] Obtain the preset temperature; reduce the start-up and shutdown temperatures based on the preset temperature to obtain the reduced start-up and shutdown temperatures.

[0132] In this embodiment, when it is determined that the cooling room is in a state of insufficient cooling capacity, the initial start-up and shutdown temperature is reduced according to the preset temperature, that is, the start-up and shutdown temperature is lowered by the preset temperature, so as to obtain the reduced start-up and shutdown temperature.

[0133] It should be noted that if insufficient cooling capacity is detected in the cooling room, the preset temperature is lowered from the current start / stop temperature to obtain a lowered start / stop temperature, and the cooling components are controlled according to the lowered start / stop temperature. If insufficient cooling capacity is detected again while the cooling components are being controlled according to the lowered start / stop temperature, the preset temperature is lowered again based on the lowered start / stop temperature until the cooling room is no longer in a state of insufficient cooling capacity.

[0134] For example, the preset temperature ranges from 1°C to 3°C.

[0135] In this embodiment of the application, adjusting the current start-up and shutdown temperatures according to the preset temperature can avoid excessive adjustment of the start-up and shutdown temperatures, which could lead to excessively low indoor temperatures in the refrigeration room.

[0136] In some embodiments, optionally, after controlling the operation of the refrigeration components based on the room temperature and the reduced start-up and shutdown temperatures, the control method for the refrigeration equipment further includes:

[0137] The second start-up duration of the timing refrigeration unit is determined by controlling the operation of the refrigeration unit based on the room temperature and the reduced start-up and shutdown temperatures. When the second start-up duration reaches the second duration threshold, the adjustment parameters of the reduced start-up and shutdown temperatures are obtained. If the adjustment parameters meet the target conditions, the process returns to the step of obtaining the first start-up duration and the first start-up rate of the refrigeration unit.

[0138] In this embodiment, after obtaining the reduced start-up and shutdown temperatures, and controlling the operation of the refrigeration components according to the reduced start-up and shutdown temperatures and the collected compartment temperatures, timing begins. When the timing reaches the second duration threshold, it is determined that the control of the refrigeration compartment according to the reduced start-up and shutdown temperatures has reached a stable state. At this point, the process can return to the step of obtaining the first start-up duration and the first start-up rate of the refrigeration components, and based on the first start-up duration and the first start-up rate, it can be determined again whether the refrigeration compartment is in a state of insufficient cooling capacity.

[0139] For example, the second power-on duration ranges from 60 minutes to 240 minutes, and can be specifically selected as 180 minutes.

[0140] Specifically, the reduced start-up and shutdown temperature is the temperature obtained by subtracting a preset temperature from the current start-up and shutdown temperature. When the refrigeration components are controlled according to the reduced start-up and shutdown temperature to reach the second duration threshold, it is determined that the state inside the refrigeration room has stabilized and the adjusted parameters meet the target conditions. The system then returns to obtain the first start-up duration and the first start-up rate to re-detect the refrigeration status inside the refrigeration room. If the refrigeration room is still found to have insufficient cooling capacity, the reduced start-up and shutdown temperature is lowered again according to the preset temperature. This cycle continues until the refrigeration room is no longer found to have insufficient cooling capacity.

[0141] It should be noted that before returning to retrieve the first boot duration and the first boot rate, it is necessary to determine whether the adjustment parameters of the start-up and shutdown temperatures meet the target conditions, that is, to determine whether there are problems such as over-adjustment of the start-up and shutdown temperatures.

[0142] In this embodiment, after the refrigeration equipment operates for a second time threshold according to the reduced start-up and shutdown temperature, it returns to the step of detecting whether the refrigeration equipment is in a state of insufficient cooling capacity. By cyclically performing the detection and adjustment steps, the cooling capacity of the refrigeration room is ensured to be sufficient, thus avoiding the problem of insufficient cooling capacity caused by the refrigeration room being fully loaded.

[0143] In some embodiments, the adjustment parameters may optionally include: total temperature adjustment value and number of temperature adjustments;

[0144] The target conditions include at least one of the following: the total temperature adjustment value is less than or equal to the total adjustment value threshold, and the number of temperature adjustments is less than or equal to the number threshold.

[0145] In this embodiment, the adjustment parameters include the total temperature adjustment value for adjusting the start-up and shutdown temperatures, and the number of times the start-up and shutdown temperatures are adjusted. When the cooling capacity of the refrigeration room is insufficient, the process of detecting and lowering the start-up and shutdown temperatures is repeatedly executed. Therefore, the start-up and shutdown temperatures may be adjusted multiple times. Thus, at least one of the total temperature adjustment value and the number of temperature adjustments is obtained, and the corresponding target conditions are judged. If the target conditions are met, it is determined that the start-up and shutdown temperatures have not been over-adjusted, and the process continues to return to the step of judging whether there is insufficient cooling capacity in the refrigeration room. Otherwise, the process of judging whether there is insufficient cooling capacity in the refrigeration room stops, thus avoiding over-adjustment of the start-up and shutdown temperatures.

[0146] Specifically, the adjustment parameter is the total temperature adjustment value. If the total temperature adjustment value is less than or equal to the total adjustment value threshold, the process continues to return to the step of checking whether there is insufficient cooling capacity in the refrigeration room; otherwise, the process stops returning to the step of checking whether there is insufficient cooling capacity in the refrigeration room.

[0147] For example, the range of the total temperature adjustment threshold is from 4°C to 8°C, specifically 6°C. It should be noted that the total temperature adjustment value is an integer multiple of the preset temperature.

[0148] Specifically, the adjustment parameter is the number of temperature adjustments. If the number of temperature adjustments is less than or equal to the threshold, the process continues to return to the step of checking whether there is insufficient cooling capacity in the refrigeration room; otherwise, the process stops returning to the step of checking whether there is insufficient cooling capacity in the refrigeration room.

[0149] For example, the threshold value ranges from 2 to 5 times, and can be specifically selected as 3 times.

[0150] In this embodiment of the application, during the process of cyclically executing the steps of detecting whether there is insufficient cooling capacity and adjusting the start-stop temperature, the number of times the start-stop temperature is adjusted and / or the total value of the adjusted temperature is obtained, and it is determined whether the adjustment of the start-stop temperature is excessive. If it is detected that the adjustment of the start-stop temperature is not excessive, the process returns to the step of determining whether the cooling room has insufficient cooling capacity; otherwise, the current start-stop temperature is maintained and the system continues to operate.

[0151] In some embodiments, optionally, after determining the cooling state of the cooling room based on the first start-up duration and the first start-up rate of the cooling components, the control method for the cooling equipment further includes:

[0152] If the cooling state of the cooling room is not in a state of insufficient cooling capacity and the cooling equipment completes the target action, the timer is set for the duration of the action completion; if the duration of the action completion reaches the third duration threshold, the second start-up rate of the cooling components is obtained; if the second start-up rate is greater than or equal to the second start-up rate threshold, the operation of the cooling components is controlled according to the room temperature and the initial start-up and shutdown temperature, wherein the initial start-up and shutdown temperature is the start-up and shutdown temperature before the reduced start-up and shutdown temperature is determined.

[0153] In this embodiment, when it is detected that the cooling room is not in a state of insufficient cooling, and the time taken for the cooling equipment to complete the target action reaches the third time threshold, the second start-up rate of the cooling component at this time is obtained, that is, the second start-up rate is the start-up rate of the cooling equipment after the third time threshold of the target action is executed.

[0154] For example, the third duration threshold ranges from 60 minutes to 240 minutes.

[0155] Specifically, when it is determined that the cooling capacity of the cooling room is sufficient based on the start-up time or the first start-up rate, if the cooling equipment has performed the target action, after the third time threshold of the target action is completed, the current second start-up rate is obtained, and the second start-up rate is compared with the second start-up rate threshold. If the comparison shows that the second start-up rate is greater than or equal to the second start-up rate threshold, the cooling components are controlled to operate according to the initial stop temperature before adjustment.

[0156] Among them, the second start-up rate threshold is greater than the first start-up rate threshold. When the second start-up rate is greater than the second start-up rate threshold, it is determined that the cooling capacity of the cooling room is excessive. Therefore, the reduced start-up and shutdown temperature needs to be restored to the initial start-up and shutdown temperature.

[0157] It should be noted that the second operating rate threshold is related to the operating conditions of the refrigeration equipment. Specifically, the second operating rate threshold is determined based on the ambient temperature and the target temperature of the refrigeration room set by the user.

[0158] For example, the correspondence between the second operating rate threshold and the target temperature and ambient temperature range of the cooling room is shown in Table 4 below:

[0159] Table 4

[0160]

[0161] In this embodiment, when it is determined that the refrigeration room is not in a state of insufficient cooling capacity through the first start-up rate or start-up duration, after the refrigeration equipment performs the target action, the system detects whether there is excess cooling capacity in the refrigeration room based on the second start-up rate. When it is detected that there is excess cooling capacity when the refrigeration components are operated according to the reduced shutdown control, the system reverts to the initial start-up and shutdown temperature to control the refrigeration components, thereby ensuring the preservation effect of the food in the refrigeration room.

[0162] In some embodiments, the target action may optionally include at least one of the following: adjusting the cooling temperature of the cooling room, opening and closing the door of the cooling room, and the cooling equipment completing the defrosting action.

[0163] In this embodiment, adjusting the cooling temperature of the cooling room, opening and closing the door of the cooling room, and completing the defrosting action of the cooling equipment all affect the cooling status of the cooling room. Therefore, after the third time threshold is reached after the target action is completed, the second start-up rate is obtained, and the start-up and shutdown temperatures are further adjusted based on the obtained second start-up rate, so as to avoid the impact on the accuracy of the cooling status detection of the cooling room after the cooling equipment performs the target action.

[0164] In some embodiments, optionally, before determining the cooling state of the cooling room based on the first start-up duration and the first start-up rate of the cooling component, the control method of the cooling equipment further includes: obtaining the shutdown duration of the cooling component; and determining the first start-up rate as the ratio between the first start-up duration and the sum of durations, wherein the sum of durations is the sum of the shutdown duration and the first start-up duration.

[0165] In this embodiment of the application, the refrigeration equipment records the first start-up time of the refrigeration component in the start-up state and the shutdown time of the refrigeration component in the shutdown state. The first start-up rate can be calculated based on the first start-up time and the shutdown time, that is, the first start-up rate is the start-up rate of the refrigeration component when the refrigeration component is running according to the start-up and shutdown temperature control.

[0166] For example, the first operating rate is calculated using the following relationship (1):

[0167] First power-on rate = First power-on duration / (First power-on duration + Downtime); (1)

[0168] Figure 7 This is a second schematic flowchart illustrating a control method for a refrigeration device provided in some embodiments of this application, such as... Figure 7 As shown, a control method for a refrigeration device is proposed, including:

[0169] Step 702: Determine whether the first boot duration is less than the first duration threshold and the first boot rate is less than the first boot rate threshold. If the determination result is yes, proceed to step 704; if the determination result is no, proceed to step 710.

[0170] Step 704: Lower the start-up and shutdown temperature to the preset temperature and maintain it at the second duration threshold.

[0171] Step 706: Determine whether the total temperature adjustment value is less than or equal to the total adjustment value threshold, or whether the number of temperature adjustments is less than or equal to the number of adjustments threshold. If the result is yes, return to step 702; otherwise, proceed to step 708.

[0172] Step 708: After completing the third duration threshold of the target action, determine whether the second power-on rate is greater than or equal to the second power-on rate threshold. If the result is yes, proceed to step 712; if the result is no, proceed to step 710.

[0173] Step 710: Operate according to the current start-up and shutdown temperatures;

[0174] In this embodiment, the current start-up / stop temperature includes the reduced start-up / stop temperature and the initial start-up / stop temperature. If the initial determination at step 702 is negative, the initial start-up / stop temperature has not been adjusted; therefore, the current start-up / stop temperature is the initial start-up / stop temperature. If the initial determination at step 702 is positive, and the cycle repeats from step 706 back to step 702, the start-up / stop temperature is the reduced start-up / stop temperature; therefore, the current start-up / stop temperature is the reduced start-up / stop temperature.

[0175] Step 712: Run the machine according to the initial start-up and shutdown temperatures.

[0176] According to one embodiment of this application, Figure 8 The following is a structural block diagram of a control device for a refrigeration device provided in some embodiments of this application, such as... Figure 8 As shown, a control device 800 for a refrigeration equipment is proposed. The refrigeration equipment includes a refrigeration chamber, an air duct, and a temperature sensor. The air outlet of the air duct faces the side wall of the refrigeration chamber. The temperature sensor is located between the air outlet and the return air outlet of the air duct. The cold air output end of the refrigeration component is connected to the air outlet of the air duct. The temperature sensor is used to collect the chamber temperature of the refrigeration chamber. The control device 800 for the refrigeration equipment includes:

[0177] The acquisition module 802 is used to acquire the first start-up duration and the first start-up rate of the refrigeration component when the refrigeration component is controlled to operate according to the start-up and stop-up temperatures of the current set temperature.

[0178] The determination module 804 is used to determine the cooling status of the cooling room based on the first start-up duration and the first start-up rate;

[0179] Adjustment module 806 is used to reduce the start-up and shutdown temperature when the cooling capacity of the cooling room is insufficient;

[0180] The control module 808 is used to control the operation of the refrigeration components based on the room temperature and the reduced start-up and shutdown temperatures.

[0181] In this application's technical solution, during the process of controlling the operation of the refrigeration components according to the start-up and stop-down temperatures of the refrigeration equipment, the system determines whether the refrigeration chamber is in a state of insufficient cooling capacity due to full load by acquiring the first start-up duration and the first start-up rate of the refrigeration components. If the refrigeration chamber is detected to be in a state of insufficient cooling capacity, the refrigeration equipment controls the operation of the refrigeration components according to a lower start-up and stop-down temperature than the original start-up and stop-down temperature set at the current temperature, thereby improving the refrigeration and preservation effect of the refrigeration components on the food in the refrigeration chamber under insufficient cooling capacity conditions.

[0182] In some embodiments, optionally, the acquisition module 802 is configured to acquire a first duration threshold and a first start-up rate threshold based on the current ambient temperature and a set temperature;

[0183] The determination module 804 is used to compare the numerical relationship between the first power-on rate and the first power-on rate threshold when the first power-on duration is less than the first duration threshold.

[0184] The determination module 804 is used to determine that the cooling room is in a state of insufficient cooling capacity when the first start-up rate is less than the first start-up rate threshold.

[0185] The determination module 804 is used to determine that the cooling room is not in a state of insufficient cooling capacity when the first power-on duration is greater than or equal to the first duration threshold.

[0186] The determination module 804 is used to determine that the cooling room is not in a state of insufficient cooling capacity when the first operating rate is greater than or equal to the first operating rate threshold.

[0187] The determination module 804 is used to determine that the cooling room is not in a state of insufficient cooling capacity when the first power-on duration is greater than or equal to the first duration threshold.

[0188] The determination module 804 is used to determine that the refrigeration room is not in a state of insufficient cooling capacity when the first operating rate is greater than or equal to the first operating rate threshold.

[0189] In this embodiment, after obtaining the first start-up duration and the first start-up rate corresponding to the start-up and stop temperatures, a first duration threshold and a first start-up rate threshold matching the operating conditions are obtained. The start duration is compared with the first duration threshold and the first start-up rate is compared with the first start-up rate threshold in sequence. When it is detected that the first start-up duration is less than the first duration threshold and the first start-up rate is less than the first start-up rate, it is determined that the cooling room is in a state of insufficient cooling capacity, thereby improving the accuracy of detecting the state of insufficient cooling capacity.

[0190] In this embodiment of the application, when the first power-on duration is greater than or equal to the first duration threshold, or the first power-on rate is greater than or equal to the first power-on rate threshold, it is determined that the cooling room is not in a state of insufficient cooling capacity, which further improves the accuracy of the determination of the state of the cooling room.

[0191] In some embodiments, optionally, the acquisition module 802 is used to acquire the ambient temperature of the environment where the refrigeration equipment is located, and the target temperature of the refrigeration room;

[0192] The determination module 804 is used to determine a first duration threshold and a first start-up rate threshold based on the ambient temperature and the target temperature of the cooling room.

[0193] In this embodiment, a first duration threshold and a first start-up rate threshold are set according to the ambient temperature of the environment where the refrigeration equipment is located and the target temperature set by the refrigeration equipment, thereby improving the accuracy of the criteria for judging the refrigeration status of the refrigeration room and further improving the accuracy of judging the refrigeration status of the refrigeration room.

[0194] In some embodiments, optionally, the acquisition module 802 is used to acquire a preset temperature;

[0195] The adjustment module 806 is used to reduce the start-up and shutdown temperatures according to the preset temperature, so as to obtain the reduced start-up and shutdown temperatures.

[0196] In this embodiment of the application, adjusting the current start-up and shutdown temperatures according to the preset temperature can avoid excessive adjustment of the start-up and shutdown temperatures, which could lead to excessively low indoor temperatures in the refrigeration room.

[0197] In some embodiments, the control device 800 of the refrigeration equipment may optionally further include:

[0198] The timing module is used to time the second start-up duration of the refrigeration unit, wherein the second start-up duration is the duration for which the refrigeration unit operates based on the room temperature and the reduced start-up and shutdown temperatures;

[0199] The acquisition module 802 is used to acquire the adjustment parameters of the reduced start-up and shutdown temperature when the second start-up duration reaches the second duration threshold.

[0200] The execution module is used to return to the steps of obtaining the first start-up duration and the first start-up rate of the refrigeration component when the adjusted parameters meet the target conditions.

[0201] In this embodiment, after the refrigeration equipment operates for a second time threshold according to the reduced start-up and shutdown temperature, it returns to the step of detecting whether the refrigeration equipment is in a state of insufficient cooling capacity. By cyclically performing the detection and adjustment steps, the cooling capacity of the refrigeration room is ensured to be sufficient, thus avoiding the problem of insufficient cooling capacity caused by the refrigeration room being fully loaded.

[0202] In some embodiments, the adjustment parameters may optionally include: total temperature adjustment value and number of temperature adjustments;

[0203] The target conditions include at least one of the following: the total temperature adjustment value is less than or equal to the total adjustment value threshold, and the number of temperature adjustments is less than or equal to the number threshold.

[0204] In this embodiment of the application, during the process of cyclically executing the steps of detecting whether there is insufficient cooling capacity and adjusting the start-stop temperature, the number of times the start-stop temperature is adjusted and / or the total value of the adjusted temperature is obtained, and it is determined whether the adjustment of the start-stop temperature is excessive. If it is detected that the adjustment of the start-stop temperature is not excessive, the process returns to the step of determining whether the cooling room has insufficient cooling capacity; otherwise, the current start-stop temperature is maintained and the system continues to operate.

[0205] In some embodiments, optionally, the timing module is used to time the duration of the action when the cooling state of the cooling room is not in a state of insufficient cooling capacity and the cooling equipment has completed the target action;

[0206] The acquisition module 802 is used to acquire the second start-up rate of the cooling component when the action completion time reaches the third time threshold.

[0207] The control module 808 is used to control the operation of the refrigeration components based on the room temperature and the initial start-stop temperature when the second start-up rate is greater than or equal to the second start-up rate threshold, wherein the initial start-stop temperature is the start-stop temperature before the reduced start-stop temperature is determined.

[0208] In this embodiment, when it is determined that the refrigeration room is not in a state of insufficient cooling capacity through the first start-up rate or start-up duration, after the refrigeration equipment performs the target action, the system detects whether there is excess cooling capacity in the refrigeration room based on the second start-up rate. When it is detected that there is excess cooling capacity when the refrigeration components are operated according to the reduced shutdown control, the system reverts to the initial start-up and shutdown temperature to control the refrigeration components, thereby ensuring the preservation effect of the food in the refrigeration room.

[0209] In some embodiments, the target action may optionally include at least one of the following: adjusting the cooling temperature of the cooling room, opening and closing the door of the cooling room, and the cooling equipment completing the defrosting action.

[0210] In this embodiment, adjusting the cooling temperature of the cooling room, opening and closing the door of the cooling room, and completing the defrosting action of the cooling equipment all affect the cooling status of the cooling room. Therefore, after the third time threshold is reached after the target action is completed, the second start-up rate is obtained, and the start-up and shutdown temperatures are further adjusted based on the obtained second start-up rate, so as to avoid the impact on the accuracy of the cooling status detection of the cooling room after the cooling equipment performs the target action.

[0211] In some embodiments, optionally, the acquisition module 802 is used to acquire the downtime of the refrigeration component;

[0212] The determination module 804 is used to determine the ratio between the first power-on duration and the sum of durations as the first power-on rate, wherein the sum of durations is the sum of the downtime duration and the first power-on duration.

[0213] In this embodiment of the application, the refrigeration equipment records the first start-up time of the refrigeration component in the start-up state and the shutdown time of the refrigeration component in the shutdown state. The first start-up rate can be calculated based on the first start-up time and the shutdown time, that is, the first start-up rate is the start-up rate of the refrigeration component when the refrigeration component is running according to the start-up and shutdown temperature control.
