Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment, and particularly relates to a control method for refrigeration equipment and refrigeration equipment. Background Technology

[0002] In daily life, mobile phones, smart bracelets, in-vehicle terminals and other terminal products have become closely related to people's lives. By combining terminal products with the control of refrigeration equipment, the refrigeration equipment can be automatically turned on before the user arrives home. However, the level of intelligence of the automatic start-up control of refrigeration equipment in related technologies is not high, and it is unable to accurately provide the user with the air environment they need. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a control method and a refrigeration device, which can improve the intelligence level of the refrigeration device based on the automatic start-up control method, enhance the accuracy of the refrigeration device in providing users with the required air environment, and improve the user experience.

[0004] In a first aspect, this application provides a control method for a refrigeration device, the refrigeration device comprising: a compressor having a refrigerant, an evaporator, a fan for driving airflow at the outlet of the refrigeration device, an electronic expansion valve, a sensor for collecting environmental parameters, and a controller, wherein the controller is electrically connected to the compressor, the fan, the electronic expansion valve, and the sensor respectively; the method includes:

[0005] The controller obtains the time required for the user to reach the area where the refrigeration equipment is located and the target environmental parameters corresponding to the area.

[0006] The controller determines the target duration based on the target environmental parameters; the target duration is the time required for the refrigeration equipment to adjust the current environmental parameters of the area to the target environmental parameters while operating based on the initial control parameters.

[0007] The controller controls the operating status of at least one of the compressor, the fan, the evaporator, and the electronic expansion valve in the refrigeration equipment based on the required duration and the target duration.

[0008] According to the control method of the refrigeration equipment of this application, the controller obtains the required time for the user to reach the area where the refrigeration equipment is located and the target environmental parameters corresponding to the area. Based on the target environmental parameters, the controller determines the target time. Then, based on the required time and the target time, the controller controls the working state of at least one of the compressor, fan, evaporator and electronic expansion valve in the refrigeration equipment. This enables the refrigeration equipment to perform self-feedback control operation based on the actual situation of the user's arrival at the area where the refrigeration equipment is located and the user's desired air environment. This allows the user to enjoy the desired air environment immediately upon arriving at the area where the refrigeration equipment is located, improves the control intelligence of the refrigeration equipment based on the automatic start control method, improves the accuracy of the refrigeration equipment in providing the user with the desired air environment, and enhances the user experience.

[0009] According to one embodiment of this application, controlling the operating state of at least one of the compressor, the fan, the evaporator, and the electronic expansion valve in the refrigeration equipment based on the required duration and the target duration includes:

[0010] If the target duration exceeds the required duration, increase the current control parameters of the sub-device corresponding to the target environmental parameters;

[0011] If the target duration is less than or equal to the required duration, the cooling device is controlled to enter standby mode and the required duration is reacquired.

[0012] According to one embodiment of this application, the target duration includes a fastest duration and a slowest duration; the fastest duration is the time it takes for the sub-device corresponding to the target environmental parameter to adjust the current environmental parameter to the target environmental parameter when operating based on the maximum control parameter; the slowest duration is the time it takes for the sub-device corresponding to the target environmental parameter to adjust the current environmental parameter to the target environmental parameter when operating based on the minimum control parameter.

[0013] The step of controlling the operating state of at least one of the compressor, the fan, the evaporator, and the electronic expansion valve in the refrigeration equipment based on the required duration and the target duration includes:

[0014] If the required duration is less than or equal to the slowest duration and greater than or equal to the fastest duration, the cooling equipment is controlled based on the current environmental parameters of the area and the target environmental parameters.

[0015] If the required duration is less than the fastest duration, the sub-device is controlled based on the maximum control parameters of the sub-device corresponding to the target environmental parameters.

[0016] According to one embodiment of this application, controlling the refrigeration device based on the current environmental parameters of the region and the target environmental parameters includes:

[0017] If the user stops moving and the corresponding dwell time exceeds a set threshold, the current control parameter of the sub-device corresponding to the target environment parameter is reduced.

[0018] If the user stops moving and the corresponding dwell time is less than or equal to the set threshold, the current control parameters of the sub-device corresponding to the target environment parameter shall remain unchanged.

[0019] Upon detecting that the user has changed from being stationary to moving, the cooling equipment is controlled based on the current environmental parameters of the area and the target environmental parameters.

[0020] According to one embodiment of this application, when the required duration is less than the fastest duration, after controlling the sub-device based on the maximum control parameters of the sub-device corresponding to the target environmental parameters, the method further includes:

[0021] If the system detects that the user has stopped moving, the corresponding dwell time is greater than a set threshold, and the current environmental parameters have not been adjusted to the target environmental parameters, the controller controls the sub-device to maintain the maximum control parameters during operation.

[0022] When the system detects that the user has stopped moving, the corresponding dwell time is greater than the set threshold, and the current environmental parameters are adjusted to the target environmental parameters, the controller controls the cooling equipment based on the current environmental parameters of the area and the target environmental parameters.

[0023] According to one embodiment of this application, the target environmental parameters include multiple sub-target environmental parameters; the step of determining the target duration based on the target environmental parameters by the controller includes:

[0024] The sub-time corresponding to each of the sub-target environmental parameters is obtained respectively. The sub-time is the time when the sub-current environmental parameter of the region is adjusted to the sub-target environmental parameter of the refrigeration equipment corresponding to the sub-target environmental parameter under the condition of working based on the initial control parameters.

[0025] The maximum value among the various sub-times is determined as the target duration.

[0026] According to one embodiment of this application, obtaining the required time for the user to reach the area where the refrigeration equipment is located via the controller includes:

[0027] Based on the user's current location information and the location information of the region, determine the current distance information between the user and the region;

[0028] Based on the current distance information and the user's corresponding movement speed, the required duration is calculated.

[0029] or,

[0030] The required duration is determined based on the navigation information corresponding to the user.

[0031] According to one embodiment of this application, the target environmental parameters are determined based on the following steps:

[0032] The controller receives the user's first input.

[0033] The controller determines the target environmental parameters in response to the first input;

[0034] or,

[0035] The controller determines the target environmental parameters based on at least one of the current environmental parameters, climate information, and time information of the region; the time information is used to characterize the current season.

[0036] or,

[0037] The controller determines the target environment parameters based on the user's user characteristic information.

[0038] According to one embodiment of this application, after controlling the operating state of at least one of the compressor, the fan, and the electronic expansion valve in the refrigeration equipment based on the required duration and the target duration by the controller, the method further includes:

[0039] When multiple users are detected entering the area, and at least two of the multiple users correspond to different target environmental parameters, the controller controls the cooling device based on the target environmental parameter with higher priority and the current environmental parameter.

[0040] Secondly, this application provides a refrigeration device, comprising:

[0041] The main body of the equipment includes a compressor for compressing refrigerant, an evaporator, a fan for driving airflow at the outlet of the refrigeration equipment, and an electronic expansion valve.

[0042] The sensor is disposed on the main body of the device;

[0043] A controller, which is communicatively connected to a user terminal and / or a cloud platform and electrically connected to the sensor, is used to execute the control method for the refrigeration equipment as described in the first aspect.

[0044] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects:

[0045] By acquiring the required time for a user to reach the area where the refrigeration equipment is located and the corresponding target environmental parameters of the area through the controller, and determining the target time based on the target environmental parameters, the controller then controls the operating status of at least one of the compressor, fan, evaporator, and electronic expansion valve in the refrigeration equipment based on the required time and the target time. This enables the refrigeration equipment to perform self-feedback control operation based on the actual situation of the user's arrival at the refrigeration equipment area and the user's desired air environment. This ensures that the user can enjoy the desired air environment immediately upon arriving at the refrigeration equipment area, improves the control intelligence of refrigeration equipment based on automatic start-up control methods, enhances the accuracy of the refrigeration equipment in providing the user with the required air environment, and improves the user experience.

[0046] Furthermore, by increasing the current control parameters of the sub-device corresponding to the target environmental parameters when the target duration is greater than the required duration, and controlling the cooling equipment to enter standby mode and reacquire the required duration when the target duration is less than or equal to the required duration, the timing at which the cooling equipment begins to adjust the current environmental parameters based on the target environmental parameters can be determined based on the relationship between the target duration and the required duration. This allows the cooling equipment to operate when it is determined that it needs to start adjusting the air environment based on the relationship, and to standby when no adjustment is needed. This more accurately controls the energy consumption of the cooling equipment, enabling it to adjust the current environmental parameters to meet the user's expected target environmental parameters while saving energy.

[0047] Furthermore, before a user arrives at the area where the refrigeration equipment is located, the system compares the user's dwell time with a set threshold. If the dwell time exceeds the set threshold, the system reduces the current control parameters of the sub-devices corresponding to the target environmental parameters, thereby reducing the energy consumption of the refrigeration equipment. If the dwell time is less than or equal to the set threshold, the system maintains the current control parameters of the sub-devices corresponding to the target environmental parameters, reducing the need for repeated switching of the refrigeration equipment's operating state during short user stays and improving the stability of the refrigeration equipment's operation. When the user stays and then moves, the system automatically adjusts the control of the refrigeration equipment based on the current and target environmental parameters of the area. This provides multiple strategies for handling situations where the user stays before arriving at the area, further enhancing the intelligence of the refrigeration equipment's control and improving the user experience.

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.

[0056] The following description, in conjunction with the accompanying drawings, details the control method, control device, refrigeration equipment, electronic equipment, and readable storage medium for the refrigeration equipment provided in this application, through specific embodiments and application scenarios.

[0057] The control method for the refrigeration equipment can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0058] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets. It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer.

[0059] The control method for refrigeration equipment provided in this application embodiment can be executed by the refrigeration equipment or a functional module or entity in the refrigeration equipment that can implement the control method. The refrigeration equipment mentioned in this application embodiment includes, but is not limited to, central air conditioning, wall-mounted air conditioning, floor-standing air conditioning, evaporative cooler or refrigeration unit. The control method for refrigeration equipment provided in this application embodiment will be described below with the refrigeration equipment as the execution subject as an example.

[0060] like Figure 1 As shown, the control method of the refrigeration equipment includes steps 110, 120 and 130.

[0061] The refrigeration equipment includes: a compressor for compressing refrigerant, an evaporator, a fan for driving airflow at the outlet of the refrigeration equipment, an electronic expansion valve, sensors for collecting environmental parameters, and a controller.

[0062] The controller is electrically connected to the compressor, fan, electronic expansion valve, and sensors.

[0063] Step 110: Obtain the time required for the user to reach the area where the refrigeration equipment is located and the target environmental parameters corresponding to the area through the controller;

[0064] In this step, environmental parameters may include cooling / heating temperature, humidity, and air quality (the levels of PM2.5, formaldehyde, and other harmful gases).

[0065] The target environmental parameters are the preset environmental parameters that the area where the refrigeration equipment is located needs to achieve.

[0066] For example, target environmental parameters may include preset environmental parameters such as 26°C cooling, 27°C cooling, and 45% humidity.

[0067] The specific methods for obtaining the target environmental parameters will be described in the embodiments below, and will not be elaborated here.

[0068] In some embodiments, the time required for a user to reach the area where the refrigeration equipment is located can be preset by the user.

[0069] In some embodiments, obtaining the required time for a user to reach the area where the refrigeration equipment is located via the controller may include:

[0070] Based on the user's current location information and the region's location information, determine the user's current distance from the region;

[0071] The required time is calculated based on the current distance information and the user's corresponding movement speed;

[0072] Alternatively, the required duration can be determined based on the user's corresponding navigation information.

[0073] In this embodiment, it is understood that the required time can be obtained from the distance information between the user and the area or based on the user's navigation information.

[0074] In some embodiments, the user's current location information and movement speed can be obtained by the user's mobile phone, wristband, vehicle terminal or other location-enabled terminal products, and the location information of the area can be obtained by the positioning device set in the cooling equipment.

[0075] In some embodiments, such as Figure 2 As shown, mobile phones, wristbands, or in-vehicle terminals can connect to the user cloud (purchased by the user or integrated into the air conditioning system) via their built-in gateways to upload the user's location information and movement speed in real time. The controller of the refrigeration equipment can also connect to the user cloud via its built-in gateway, sending its own location information to the user cloud. The user cloud can monitor the user's current location and movement speed in real time, calculate the current distance between the user and the area where the refrigeration equipment is located, and calculate the required duration based on the current distance and the user's corresponding movement speed. This required duration is then sent to the controller of the refrigeration equipment for appropriate control. Alternatively, the required duration can be obtained directly from the navigation information of the mobile phone, wristband, or in-vehicle terminal, and uploaded to the user cloud connected to its built-in gateway. The user cloud then sends this information to the controller for control of the refrigeration equipment.

[0076] According to the control method for the refrigeration equipment provided in the embodiments of this application, the current distance information between the user and the area is determined based on the user's current location information and the area's location information. The required duration is calculated based on the current distance information and the user's corresponding movement speed. Alternatively, the required duration can be determined based on the user's corresponding navigation information. This allows for multiple methods of determining the required duration, improving the flexibility of the control method.

[0077] Step 120: Determine the target duration based on the target environmental parameters using the controller;

[0078] In this step, the target duration is the time it takes for the refrigeration equipment to adjust the current environmental parameters of the area to the target environmental parameters while operating based on the initial control parameters.

[0079] In actual implementation, the target duration can be obtained based on experimental data.

[0080] The initial control parameters can be the control parameters when the refrigeration equipment just starts working.

[0081] These control parameters can include the control parameters of each sub-device in the refrigeration equipment.

[0082] Sub-equipment may include compressors, fans, evaporators, and electronic expansion valves, etc.

[0083] Control parameters can be understood as parameters that control the operation of each sub-device, such as the compressor frequency.

[0084] In actual execution, the initial control parameters can be the control parameters under normal operating conditions of the refrigeration equipment, or they can be control parameters based on user-defined settings.

[0085] The current environmental parameters refer to the environmental parameters of the area where the refrigeration equipment is located.

[0086] Step 130: Control the operating status of at least one of the compressor, fan, evaporator and electronic expansion valve in the refrigeration equipment based on the required duration and target duration using the controller.

[0087] In this step, it is understood that the operating status of at least one sub-device in the refrigeration equipment can be controlled by the time required for the user to reach the area where the refrigeration equipment is located and the target time for the refrigeration equipment to adjust the current environmental parameters to the target environmental parameters.

[0088] In actual implementation, the working state of at least one sub-device of the refrigeration equipment can be controlled based on the relationship between the required duration and the target duration, so that the refrigeration equipment can adjust the current environmental parameters to the target environmental parameters within the required duration. This ensures that when the user arrives at the area where the refrigeration equipment is located, the environmental parameters of the current area have met the user's expectations, thus improving the user experience.

[0089] The required time and the target time have different relationships, and the working status of the refrigeration equipment varies.

[0090] For example, if the target duration is less than the required duration, the refrigeration equipment can be controlled to operate with the initial control parameters; if the target duration is greater than the required duration, the refrigeration equipment can be controlled to operate with the control parameters at maximum efficiency, so that when the user arrives at the area where the refrigeration equipment is located, the environmental parameters of the current area can meet the user's expectations.

[0091] In this application, compared to related technologies such as Wi-Fi control, no manual operation is required. The controller can obtain the required time for the user to reach the area where the cooling equipment is located and the corresponding target environmental parameters. Based on these parameters, the controller determines the target time, allowing for a more intuitive assessment of the user's movement status. Compared to controlling the cooling equipment based on distance, this approach further considers the impact of the user's movement speed and unexpected situations, making the control process more realistic. Furthermore, the target time can be flexibly updated according to complex and changing circumstances, thus adaptively adjusting the operating parameters of the cooling equipment. Finally, based on the required and target times, the controller controls the compressor, fan, and evaporator within the cooling equipment. The operating state of at least one of the generator and electronic expansion valve allows for automatic control of the refrigeration equipment based on the relationship between the time it takes for the user to arrive at the area and the time it takes for the refrigeration equipment to adjust the air environment in the area to the user's desired air environment. This enables the refrigeration equipment to automatically execute a control process corresponding to the relationship, allowing the refrigeration equipment to perform self-feedback control operation based on the actual situation of the user's arrival at the refrigeration equipment area and the user's desired air environment. This ensures that the user can enjoy the required air environment upon arrival at the refrigeration equipment area, improves the control intelligence of the refrigeration equipment based on the automatic start control method, enhances the accuracy of the refrigeration equipment in providing the user with the required air environment, and improves the user experience.

[0092] According to the control method for refrigeration equipment provided in this application embodiment, the controller obtains the required time for the user to reach the area where the refrigeration equipment is located and the target environmental parameters corresponding to the area. Based on the target environmental parameters, the controller determines the target time. Then, based on the required time and the target time, the controller controls the working state of at least one of the compressor, fan, evaporator, and electronic expansion valve in the refrigeration equipment. This enables the refrigeration equipment to perform self-feedback control operation based on the actual situation of the user's arrival at the area where the refrigeration equipment is located and the user's desired air environment. This allows the user to enjoy the desired air environment immediately upon arriving at the area where the refrigeration equipment is located, improving the control intelligence of the refrigeration equipment based on the automatic start control method, increasing the accuracy of the refrigeration equipment in providing the user with the desired air environment, and enhancing the user experience.

[0093] In some embodiments, controlling the operating state of at least one of the compressor, fan, evaporator, and electronic expansion valve in the refrigeration equipment based on the required duration and the target duration may include:

[0094] If the target duration exceeds the required duration, increase the current control parameters of the sub-devices corresponding to the target environmental parameters;

[0095] If the target duration is less than or equal to the required duration, the cooling equipment is controlled to enter standby mode and the required duration is reacquired.

[0096] In this embodiment, the sub-device corresponding to the target environmental parameter can be understood as the sub-device involved in controlling the refrigeration equipment to make the environmental parameters in the area reach the target environmental parameter.

[0097] For example, when the target environmental parameter is a preset temperature of 26°C for cooling, the compressor of the refrigeration equipment compresses the refrigerant, the electronic expansion valve throttles and reduces the pressure of the high-pressure liquid refrigerant, turning it into a low-temperature, low-pressure liquid or liquid-gas mixture, and the evaporator absorbs heat from the indoor air, causing the liquid refrigerant to evaporate into a gaseous, low-temperature refrigerant, thereby lowering the indoor temperature; thus, the target environmental parameter of 26°C for cooling can be achieved. Here, the compressor, electronic expansion valve, and evaporator are all sub-equipment corresponding to the target environmental parameter of 26°C for cooling.

[0098] Standby mode is a low-energy state in which the cooling device maintains a basic power connection but does not operate.

[0099] Understandably, when comparing the target duration and the required duration, and the target duration is greater than the required duration, the current control parameters of the sub-device corresponding to the target environmental parameters can be increased. This allows the cooling equipment to adjust the current environmental parameters faster based on the increased current control parameters. Conversely, when the target duration is less than or equal to the required duration, the cooling equipment can be put into standby mode and the required duration can be reacquired until the target duration exceeds the required duration. In this case, the current control parameters of the sub-device corresponding to the target environmental parameters can be increased, allowing the cooling equipment to adjust the current environmental parameters faster based on the increased current control parameters.

[0100] According to the control method of the refrigeration equipment provided in the embodiments of this application, when the target duration is greater than the required duration, the current control parameters of the sub-device corresponding to the target environmental parameters are increased; when the target duration is less than or equal to the required duration, the refrigeration equipment is controlled to enter a standby state and the required duration is reacquired. Based on the relationship between the target duration and the required duration, the timing at which the refrigeration equipment begins to adjust the current environmental parameters based on the target environmental parameters can be determined. This allows the refrigeration equipment to work when it is determined that it needs to start adjusting the air environment based on the relationship, and to standby when no adjustment is needed. This more accurately controls the energy consumption of the refrigeration equipment, enabling the refrigeration equipment to adjust the current environmental parameters to meet the user's expected target environmental parameters while saving energy consumption.

[0101] In some embodiments, the target duration includes a fastest duration and a slowest duration; controlling the operating state of at least one of the compressor, fan, evaporator, and electronic expansion valve in the refrigeration equipment based on the required duration and the target duration may include:

[0102] When the required duration is less than or equal to the slowest duration and greater than or equal to the fastest duration, the cooling equipment is controlled based on the current environmental parameters and target environmental parameters of the region.

[0103] When the required duration is less than the fastest duration, the sub-device is controlled based on the maximum control parameters of the sub-device corresponding to the target environmental parameters.

[0104] In this embodiment, the fastest duration is the time it takes for the sub-device corresponding to the target environmental parameters to adjust the current environmental parameters to the target environmental parameters when it is operating based on the maximum control parameters.

[0105] The slowest duration is the time it takes for the sub-device corresponding to the target environmental parameters to adjust the current environmental parameters to the target environmental parameters when operating based on the minimum control parameters.

[0106] The maximum control parameter is the control parameter that enables the sub-equipment to achieve maximum working efficiency.

[0107] Correspondingly, the minimum control parameter is the control parameter that enables the sub-device to achieve the minimum working efficiency.

[0108] Controlling refrigeration equipment based on the current and target environmental parameters of the region can be understood as automatically adjusting and controlling the refrigeration equipment based on the constantly changing current and target environmental parameters over time.

[0109] In actual implementation, automatic adjustment and control of refrigeration equipment can be based on any control mode of the refrigeration equipment to control the refrigeration equipment. The arbitrary control mode can include the normal mode or the energy-saving mode, etc.

[0110] Understandably, the target duration can be further divided into the fastest duration and the slowest duration, and the required duration can be compared with the fastest duration and the slowest duration respectively. The different magnitudes of the required duration and the fastest and slowest duration indicate different operating states of the refrigeration equipment, thereby further improving the accuracy of controlling the refrigeration equipment.

[0111] Specifically, when the required duration is less than or equal to the slowest duration and greater than or equal to the fastest duration, i.e., the required duration is between the slowest and fastest durations, the cooling equipment can be automatically adjusted and controlled based on the current environmental parameters and target environmental parameters that change over time, using any control mode.

[0112] If the required time is less than the fastest time, the sub-device can be controlled based on the maximum control parameters of the sub-device corresponding to the target environmental parameters, thereby enabling the refrigeration equipment to adjust the current environmental parameters to the target environmental parameters more quickly.

[0113] According to the control method for the refrigeration equipment provided in the embodiments of this application, when the required duration is less than or equal to the slowest duration and greater than or equal to the fastest duration, the refrigeration equipment is controlled based on the current environmental parameters and target environmental parameters of the region; when the required duration is less than the fastest duration, the sub-device is controlled based on the maximum control parameter of the sub-device corresponding to the target environmental parameters. The target duration can be further divided into the fastest duration and the slowest duration, and the target duration can be further compared with the fastest duration and the slowest duration, thereby more accurately controlling the time point at which the refrigeration equipment starts to adjust the current environmental parameters based on the target environmental parameters, and further saving the energy consumption of the refrigeration equipment.

[0114] In some embodiments, controlling the cooling equipment based on the current environmental parameters and target environmental parameters of the area may include:

[0115] If the user stops moving and the corresponding dwell time exceeds a set threshold, the current control parameter of the sub-device corresponding to the target environmental parameter is reduced.

[0116] If the user stops moving and the corresponding dwell time is less than or equal to a set threshold, the current control parameters of the sub-device corresponding to the target environment parameters remain unchanged.

[0117] When a user is detected to have changed from being stationary to moving, the cooling equipment is controlled based on the current environmental parameters of the area and the target environmental parameters.

[0118] In this embodiment, the threshold is set to a pre-defined threshold for the duration during which the user stops moving.

[0119] In actual implementation, the threshold can be set by the user. For example, the threshold can be set to 5 minutes, 10 minutes or 20 minutes. Of course, in other embodiments, the threshold can also be set to other durations. This application does not limit this.

[0120] It is understandable that if a user stays at a certain location for a certain period of time before reaching the area where the refrigeration equipment is located, the working state of the refrigeration equipment can be controlled based on the stay time; that is, the working state of the refrigeration equipment will be different depending on the stay time.

[0121] Specifically, if the dwell time exceeds a set threshold, the current control parameters of the sub-device corresponding to the target environmental parameters are reduced, thereby slowing down the adjustment speed of the refrigeration equipment. If the dwell time is less than or equal to the set threshold, the current control parameters of the sub-device corresponding to the target environmental parameters are kept unchanged, and the refrigeration equipment continues to be controlled based on the working state of the refrigeration equipment before the user stopped. If the user changes from stopping to moving again, the refrigeration equipment is automatically adjusted and controlled based on the current environmental parameters and target environmental parameters that change over time, according to any control mode.

[0122] According to the control method for refrigeration equipment provided in this application embodiment, before a user arrives at the area where the refrigeration equipment is located, the method compares the user's dwell time with a set threshold. If the dwell time is greater than the set threshold, the current control parameters of the sub-device corresponding to the target environmental parameters are reduced, thereby reducing the energy consumption of the refrigeration equipment. If the dwell time is less than or equal to the set threshold, the current control parameters of the sub-device corresponding to the target environmental parameters are kept unchanged, reducing the need for repeated switching of the refrigeration equipment's operating state when the user has a short stay, thus improving the stability of the refrigeration equipment's operation. When the user stays and then moves, the refrigeration equipment is automatically adjusted and controlled based on the current environmental parameters of the area and the target environmental parameters, thereby realizing multiple coping strategies for situations where the user stays before arriving at the area, further improving the intelligence level of the refrigeration equipment's control, and further enhancing the user experience.

[0123] In some embodiments, when the required duration is less than the fastest duration, after controlling the sub-device based on the maximum control parameters of the sub-device corresponding to the target environmental parameters, the method may further include:

[0124] If the system detects that the user has stopped moving, the corresponding dwell time is greater than the set threshold, and the current environmental parameters have not been adjusted to the target environmental parameters, the controller will control the sub-device to maintain the maximum control parameters and operate accordingly.

[0125] When the system detects that the user has stopped moving, the corresponding dwell time exceeds a set threshold, and the current environmental parameters are adjusted to the target environmental parameters, the controller controls the cooling equipment based on the current and target environmental parameters of the area.

[0126] In this embodiment, it can be understood that, after controlling the sub-device based on the maximum control parameters of the sub-device corresponding to the target environmental parameters when the required duration is less than the fastest duration, and when the user stops moving and the duration of stay exceeds the set threshold, the working state of the cooling device can be further controlled based on whether the current environmental parameters have reached the target environmental parameters.

[0127] In the case where the current environmental parameters have not reached the target environmental parameters, the sub-device can continue to operate at the maximum control parameters, thereby accelerating the adjustment of the current environmental parameters to the target environmental parameters; while when the current environmental parameters have reached the target environmental parameters, the refrigeration equipment can be controlled based on the current environmental parameters and the target environmental parameters of the area, that is, the refrigeration equipment can be automatically adjusted, thereby saving the energy consumption of the refrigeration equipment.

[0128] According to the control method of the refrigeration equipment provided in the embodiments of this application, after controlling the sub-device based on the maximum control parameters of the sub-device corresponding to the target environmental parameters when the required duration is less than the fastest duration, and when the user stops moving and the duration of stay is greater than a set threshold, the working state of the refrigeration equipment is further controlled based on whether the current environmental parameters have reached the target environmental parameters. This can further improve the intelligent control program of the refrigeration equipment and further enhance the user experience.

[0129] In some embodiments, controlling the operating state of at least one of the compressor, fan, evaporator, and electronic expansion valve in the refrigeration equipment based on the required duration and the target duration may include:

[0130] Control at least one sub-device in the refrigeration equipment based on the required duration and the target duration until the current environmental parameters are adjusted to the target environmental parameters, and then control the refrigeration equipment based on the current environmental parameters and the target environmental parameters.

[0131] In this embodiment, it can be understood that if the current environmental parameters have been adjusted to the target environmental parameters before the user arrives at the area where the refrigeration equipment is located, the refrigeration equipment can be automatically adjusted and controlled based on the current environmental parameters and the target environmental parameters.

[0132] According to the control method of the refrigeration equipment provided in the embodiments of this application, by controlling at least one sub-device of the refrigeration equipment based on the required duration and the target duration until the current environmental parameters are adjusted to the target environmental parameters, the refrigeration equipment can be controlled based on the current environmental parameters and the target environmental parameters. This can automatically adjust and control the refrigeration equipment based on the current environmental parameters and the target environmental parameters before the user arrives at the area where the refrigeration equipment is located, but when the current environmental parameters have reached the user's expected target environmental parameters. This can improve the user experience while saving energy consumption of the refrigeration equipment.

[0133] In some embodiments, the target environmental parameters include multiple sub-target environmental parameters; determining the target duration based on the target environmental parameters by the controller may include:

[0134] The sub-time corresponding to each sub-target environmental parameter is obtained. The sub-time is the time when the sub-current environmental parameter of the area is adjusted to the sub-target environmental parameter based on the initial control parameters of the sub-device in the refrigeration equipment.

[0135] The maximum value among all sub-times is determined as the target duration.

[0136] In this embodiment, it can be understood that the target environment parameter may include multiple sub-target environment parameters.

[0137] For example, target environmental parameters may include sub-target environmental parameters such as cooling to 26°C and humidity to 50%.

[0138] Correspondingly, current environmental parameters may include sub-current environmental parameters such as current ambient temperature and current ambient humidity.

[0139] The sub-times corresponding to the environmental parameters of each sub-target can be different.

[0140] For example, the sub-time when the temperature of the area where the refrigeration equipment is located is adjusted to 26°C is 15 minutes, and the sub-time when the humidity of the area where the refrigeration equipment is located is adjusted to 50% is 20 minutes.

[0141] In actual execution, when the controller determines the target duration based on the target environmental parameters, the sub-times corresponding to each sub-target environmental parameter included in the target environmental parameters can be compared. The maximum value among the sub-times, i.e. the sub-time corresponding to the slowest-adjusted sub-target environmental parameter, is determined as the target duration. This facilitates the comparison between the time required for the user to reach the area where the refrigeration equipment is located and this sub-time. As a result, when the user reaches the area where the refrigeration equipment is located, each current sub-environmental parameter can be adjusted to the respective sub-target environmental parameter.

[0142] According to the control method for refrigeration equipment provided in the embodiments of this application, when the target environmental parameters include multiple sub-target environmental parameters, the sub-time corresponding to each sub-target environmental parameter is obtained respectively, and the maximum value among each sub-time is determined as the target duration. This makes the determined target duration more reasonable, so that when the user arrives at the area where the refrigeration equipment is located, each sub-current environmental parameter can be adjusted to each sub-target environmental parameter, thereby improving the reliability of the control method.

[0143] In some embodiments, after controlling the operating state of at least one of the compressor, fan, evaporator, and electronic expansion valve in the refrigeration equipment based on the desired duration and the target duration by a controller, the method may further include:

[0144] Upon detecting that a user has entered the area, the controller controls the cooling equipment based on the current environmental parameters and target environmental parameters of the area.

[0145] In this embodiment, it can be understood that when a user enters the area where the refrigeration equipment is located, the refrigeration equipment can be automatically adjusted and controlled based on the current environmental parameters and target environmental parameters of the area.

[0146] In some embodiments, users can also perform routine control of the refrigeration equipment after entering the area where the refrigeration equipment is located, such as adjusting the set temperature, air direction, and air speed.

[0147] According to the control method of the refrigeration equipment provided in the embodiments of this application, when a user enters the area, the controller controls the refrigeration equipment based on the current environmental parameters and target environmental parameters of the area. When a user arrives at the area, the controller automatically adjusts and controls the refrigeration equipment based on the current environmental parameters and target environmental parameters of the area, so that the refrigeration equipment enters the normal control logic, thereby facilitating the user's subsequent control of the refrigeration equipment and improving the user experience.

[0148] In some embodiments, after controlling the operating state of at least one of the compressor, fan, evaporator, and electronic expansion valve in the refrigeration equipment based on the desired duration and the target duration by a controller, the method may further include:

[0149] When multiple users are detected entering the area, and at least two of the users have different target environmental parameters, the controller controls the cooling equipment based on the target environmental parameter with higher priority and the current environmental parameters.

[0150] In this embodiment, it can be understood that when multiple users enter the area and each user has different target environmental parameters, the target environmental parameters corresponding to each user can be sorted according to priority, so that the controller can automatically adjust and control the cooling equipment based on the target environmental parameters with higher priority and the current environmental parameters.

[0151] In actual execution, the priority of the target environment parameters for each user can be customized by the user.

[0152] For example, the priority of the target environment parameters for the elderly or children can be set higher than that for general users, so that when the elderly or children and general users enter the area at the same time, the expected target environment parameters of the elderly or children will be given priority.

[0153] According to the control method of the refrigeration equipment provided in the embodiments of this application, when multiple users are detected entering the area and at least two of the users correspond to different target environmental parameters, the controller controls the refrigeration equipment based on the target environmental parameter with higher priority and the current environmental parameter. This allows the refrigeration equipment to customize the control priority according to the user's needs, thereby improving the intelligence level of the refrigeration equipment control and enhancing the user experience.

[0154] The method for determining the target environmental parameters is explained below.

[0155] In some embodiments, the target environmental parameters can be determined based on the following steps:

[0156] The controller receives the user's initial input.

[0157] The target environmental parameters are determined by the controller responding to the first input.

[0158] In this embodiment, the first input is the user setting the target environment parameters.

[0159] The first input can be in at least one of the following ways:

[0160] Firstly, the first input can be a touch operation, including but not limited to click, swipe, and press operations.

[0161] In this embodiment, receiving the user's first input can be receiving the user's touch operation on the display area of ​​the mobile terminal's screen.

[0162] In actual operation, the first input can be achieved through the display screen of a mobile terminal, such as a mobile phone, which is connected to the controller of the refrigeration equipment.

[0163] For example, the terminal display shows a control interface, and the user touches the area for inputting target environmental parameters to input the target environmental parameters, thus achieving the first input.

[0164] Secondly, the first input can be a physical button input.

[0165] In this embodiment, the user's first input can be received through a remote control device that communicates with the controller of the refrigeration equipment or through a physical button on the refrigeration equipment that communicates with the controller. This can be receiving the user's operation of pressing the corresponding physical button; the first input can also be a combination operation of pressing multiple physical buttons simultaneously.

[0166] Thirdly, the first input can be voice input.

[0167] In this embodiment, when the refrigeration device receives a voice message such as "Set target environmental parameter 1", it triggers the controller to set target environmental parameter 1.

[0168] Of course, in other embodiments, the first input may also be in other forms, including but not limited to character input, etc., which can be determined according to actual needs, and this application embodiment does not limit it.

[0169] It is understandable that the target environment parameters can be determined by receiving the user's initial input.

[0170] In some embodiments, the target environmental parameters can also be determined based on the following steps:

[0171] The controller determines the target environmental parameters based on at least one of the region's current environmental parameters, climate information, and time information.

[0172] In this embodiment, climate information may include outdoor temperature and weather information.

[0173] Time information is used to represent the current season.

[0174] Understandably, refrigeration equipment can also automatically determine target environmental parameters based on the current environmental parameters, climate information, and time information of the area it is located in.

[0175] In some embodiments, a correspondence table between target environmental parameters and environmental parameters, climate information, and time information can be pre-constructed, so that the refrigeration equipment can obtain the target environmental parameters based on the table query.

[0176] In some embodiments, a predictive model for determining target environmental parameters can also be trained based on a neural network model, based on environmental parameters, climate information, and time information, thereby determining the target environmental parameters based on the current environmental parameters, climate information, and time information.

[0177] Of course, in other embodiments, the determination of target environmental parameters based on current environmental parameters, climate information, and time information can also be achieved in other ways, and this application does not limit it here.

[0178] In some embodiments, the target environmental parameters can also be determined based on the following steps:

[0179] The controller determines the target environment parameters based on the user's user characteristics information.

[0180] In this embodiment, user characteristic information may include user group characteristic information and user age characteristic information, etc.

[0181] The user's group characteristics information may include: children, youth, pregnant women, and the elderly, etc.

[0182] Users' age characteristics can include age groups such as 0 to 6 years old, 6 to 12 years old, 12 to 18 years old, and 18 to 35 years old.

[0183] In actual operation, the refrigeration equipment can also automatically determine the target environmental parameters corresponding to the user based on the user's user characteristics information.

[0184] The specific method of automatically determining the target environmental parameters corresponding to a user based on the user's user characteristic information can be similar to the method of automatically determining the target environmental parameters based on the current environmental parameters, climate information and time information of the region, as described above, and will not be elaborated here.

[0185] The control method for refrigeration equipment provided in the embodiments of this application can improve the flexibility and adaptability of the target environmental parameter determination method by providing multiple methods for determining the target environmental parameters, thereby enhancing the user experience.

[0186] The control method for refrigeration equipment provided in this application can be executed by a control device for the refrigeration equipment. This application uses the example of a control device for the refrigeration equipment executing the control method to illustrate the control device for the refrigeration equipment provided in this application.

[0187] In some embodiments, this application also provides a control device for a refrigeration device.

[0188] like Figure 3 As shown, the control device of the refrigeration equipment includes: a first processing module 310, a second processing module 320 and a third processing module 330.

[0189] The first processing module 310 is used to obtain the required time for the user to reach the area where the refrigeration equipment is located and the target environmental parameters corresponding to the area through the controller.

[0190] The second processing module 320 is used to determine the target duration based on the target environmental parameters through the controller; the target duration is the time required for the refrigeration equipment to adjust the current environmental parameters of the area to the target environmental parameters when operating based on the initial control parameters.

[0191] The third processing module 330 is used to control the operating status of at least one of the compressor, fan, evaporator and electronic expansion valve in the refrigeration equipment based on the required duration and target duration by the controller.

[0192] According to the control device for the refrigeration equipment provided in the embodiments of this application, the controller obtains the required time for the user to reach the area where the refrigeration equipment is located and the target environmental parameters corresponding to the area. Based on the target environmental parameters, the controller determines the target time. Then, based on the required time and the target time, the controller controls the working state of at least one of the compressor, fan, evaporator, and electronic expansion valve in the refrigeration equipment. This enables the refrigeration equipment to perform self-feedback control operation based on the actual situation of the user's arrival at the area where the refrigeration equipment is located and the user's desired air environment. This allows the user to enjoy the desired air environment immediately upon arriving at the area where the refrigeration equipment is located, improving the control intelligence of the refrigeration equipment based on the automatic start control method, increasing the accuracy of the refrigeration equipment in providing the user with the desired air environment, and enhancing the user experience.

[0193] In some embodiments, the first processing module 310 may also be used for:

[0194] Based on the user's current location information and the region's location information, determine the user's current distance from the region;

[0195] The required time is calculated based on the current distance information and the user's corresponding movement speed;

[0196] or,

[0197] The required duration is determined based on the user's corresponding navigation information.

[0198] In some embodiments, the second processing module 320 may also be used for:

[0199] The target environmental parameters include multiple sub-target environmental parameters; the sub-time corresponding to each sub-target environmental parameter is obtained. The sub-time is the time when the sub-current environmental parameter of the area is adjusted to the sub-target environmental parameter in the refrigeration equipment corresponding to the sub-target environmental parameter, based on the initial control parameters.

[0200] The maximum value among all sub-times is determined as the target duration.

[0201] In some embodiments, the third processing module 330 can also be used for:

[0202] If the target duration exceeds the required duration, increase the current control parameters of the sub-devices corresponding to the target environmental parameters;

[0203] If the target duration is less than or equal to the required duration, the cooling equipment is controlled to enter standby mode and the required duration is reacquired.

[0204] In some embodiments, the third processing module 330 can also be used for:

[0205] The target duration includes the fastest duration and the slowest duration; the fastest duration is the time it takes for the sub-device corresponding to the target environmental parameters to adjust its current environmental parameters to the target environmental parameters when operating based on the maximum control parameters; the slowest duration is the time it takes for the sub-device corresponding to the target environmental parameters to adjust its current environmental parameters to the target environmental parameters when operating based on the minimum control parameters.

[0206] When the required duration is less than or equal to the slowest duration and greater than or equal to the fastest duration, the cooling equipment is controlled based on the current environmental parameters and target environmental parameters of the region.

[0207] When the required duration is less than the fastest duration, the sub-device is controlled based on the maximum control parameters of the sub-device corresponding to the target environmental parameters.

[0208] In some embodiments, the third processing module 330 can also be used for:

[0209] If the user stops moving and the corresponding dwell time exceeds a set threshold, the current control parameter of the sub-device corresponding to the target environmental parameter is reduced.

[0210] If the user stops moving and the corresponding dwell time is less than or equal to a set threshold, the current control parameters of the sub-device corresponding to the target environment parameters remain unchanged.

[0211] When a user is detected to have changed from being stationary to moving, the cooling equipment is controlled based on the current environmental parameters of the area and the target environmental parameters.

[0212] In some embodiments, the device may further include a fourth processing module for:

[0213] If the required duration is less than the fastest duration, based on the maximum control parameters of the sub-device corresponding to the target environmental parameters, after controlling the sub-device, if the user stops moving, the corresponding dwell time is greater than the set threshold, and the current environmental parameters are not adjusted to the target environmental parameters, the controller controls the sub-device to maintain the maximum control parameters and work.

[0214] When the system detects that the user has stopped moving, the corresponding dwell time exceeds a set threshold, and the current environmental parameters are adjusted to the target environmental parameters, the controller controls the cooling equipment based on the current and target environmental parameters of the area.

[0215] In some embodiments, the device may further include a fifth processing module for:

[0216] After controlling the operating state of at least one of the compressor, fan, evaporator and electronic expansion valve in the refrigeration equipment based on the required duration and target duration by the controller, when multiple users are detected entering the area and at least two of the multiple users correspond to different target environmental parameters, the refrigeration equipment is controlled by the controller based on the target environmental parameter with higher priority and the current environmental parameter.
