Technical Field
[0001] The invention relates to the technical field of air energy heat pumps, and in particular to a protection device and a control method for improving the energy efficiency of a heat pump. Background Art
[0002] An air source heat pump is a device that uses the heat energy in the air for heating or cooling. Through a refrigeration cycle process, the heat in the air is transferred to water or air, thereby achieving indoor temperature control. The protective nets of existing low-temperature air source heat pumps are relatively simple and cannot achieve air volume regulation. The entire heat pump system generally has uneven upper and lower air volumes, which affects the energy efficiency of the heat pump. The existing low-temperature air source heat pumps have varying technologies in defrosting, and defrosting energy consumption has become the most important factor affecting heat pumps under low-temperature conditions. The current mainstream heat pumps have a very large amount of heat dissipation in the low-temperature environment when defrosting under low-temperature conditions, resulting in very high defrosting energy consumption.
[0003] Prior art 1, application number: CN202311421658.5 discloses a control method, device, and air source heat pump system for an air source heat pump system. By obtaining the current start status of each group of air source heat pump units, and detecting the inlet and outlet water temperature difference, load rate, cooling capacity, and heating capacity of the system, different control strategies are adopted for each group of air source heat pump units that are turned on in different working modes. Then, through the dynamic grouping control method, the water mixing problem caused by the asynchronous start and stop frequency of each group of air source heat pump units in the traditional system is solved, thereby improving the system's operating energy efficiency. However, its structure is relatively complex, the operation is cumbersome, and the use and manufacturing costs of the air source heat pump are increased.
[0004] Prior art 2, application number: CN202410496501.7 discloses an air source heat pump control method, system and heat pump, including data processing of the historical operation data of the air source heat pump to obtain the performance loss characterization value of the air source heat pump, and at the same time, combined with monitoring of the subordinate operation area of the air source heat pump, the temperature adjustment reference rate of the air source heat pump during actual operation is obtained, and the compressor target execution adjustment speed of the air source heat pump is analyzed to finally achieve precise control of the compressor speed of the air source heat pump, so that the air source heat pump can dynamically adjust the compressor of the air source heat pump according to real-time demand, which can improve the energy efficiency of the air source heat pump and reduce energy consumption, and provide effective support for the control effect and operation efficiency of the air source heat pump, thereby effectively optimizing the operation efficiency and overall control coordination of the air source heat pump. However, the structure of the protective net is relatively simple, and the air volume cannot be adjusted, which affects the energy efficiency of the heat pump.
[0005] Prior art three, application number: CN 202310930326.3 discloses a design and selection method for frost-suppressing air source heat pumps suitable for different regions, including the following steps: a conventional air source heat pump temperature drop ΔTa<6℃ achieves frost suppression energy efficiency; when ΔTa is greater than 6℃, a frost suppression heat pump needs to be selected; when 6<ΔTa≤8, select a frost suppression heat pump with CICO=8, when 8<ΔTa≤10, select a frost suppression heat pump with CICO=10, and when 10<ΔTa, select a frost suppression heat pump with CICO=12; calculate the defrosting equivalent temperature drop ΔTa` of the frost suppression air source heat pump under the CICO; verify whether the selected frost suppression air source heat pump meets the frost suppression energy efficiency, if it does not meet ΔTa`<6℃, reselect the air source heat pump CICO; until the corresponding region meets the frost suppression energy efficiency, that is, the design and selection of the frost suppression air source heat pump; although it is suitable for different regions and different climatic conditions. However, the amount of heat dissipated in the low-temperature environment during defrosting is very large, resulting in very high defrosting energy consumption.
[0006] At present, the existing technologies 1, 2 and 3 have the problem that the protective net structure is simple and the air volume cannot be adjusted, which affects the energy efficiency of the heat pump; the heat dissipation to the low-temperature environment during defrosting is large, resulting in high energy consumption for defrosting. Therefore, the present invention provides a protective device and a control method for improving the energy efficiency of the heat pump, which is installed at the air inlet position of the heat pump fin heat exchanger, and adopts an electric openable and closable shutter design. The shutter can be adjusted to a full opening angle according to the height of the fin and the air volume of the fan to achieve uniform air volume above and below the fin heat exchanger. At the same time, it can be closed when the heat pump is not in use or defrosting, so as to protect the heat pump fin heat exchanger and reduce the energy consumption of defrosting.

[0058] Example 1: Figure 1 As shown, an embodiment of the present invention provides a control method for a protective device for improving the energy efficiency of a heat pump, comprising the following steps:
[0059] S100: obtaining real-time monitoring of the heat pump operating status, including monitoring data such as operating temperature, fan status and defrosting conditions, through devices such as temperature sensors, pressure sensors and air flow sensors;
[0060] S200: Feedback the monitoring data to the controller of the heat pump to determine whether the heat pump is in normal operation, shut down, or needs to be defrosted;
[0061] S300: When the heat pump is in normal operation, the shutters will be adjusted to open at an angle; when the heat pump is shut down, powered off, or enters the defrost stage, a command will be issued to automatically close the protective device; when the heat pump reaches the defrost conditions, the shutters will be automatically closed; when the heat pump completes defrosting and detects the conditions to exit defrosting, the shutters will be reopened to return to the fully open state, and the heat pump will operate normally.
[0062] The working principle and beneficial effects of the above technical solution are as follows: the present embodiment first obtains the real-time monitoring of the heat pump operating state, including monitoring data such as operating temperature, fan state and defrosting conditions, through devices such as temperature sensors, pressure sensors and wind flow sensors; secondly, the monitoring data is fed back to the controller of the heat pump to determine whether the heat pump is in normal operation, shutdown or needs to be defrosted; finally, when the heat pump is in normal operation, the shutter is adjusted to an opening angle; when the heat pump is shut down, powered off or enters the defrosting stage, an instruction will be issued to automatically close the protective device; finally, when the heat pump reaches the defrosting condition, the shutter is automatically closed; when the heat pump completes defrosting and detects the conditions for exiting defrosting, the shutter will be reopened and restored to a fully open state, and the heat pump operates normally. Step S100 of the above scheme obtains real-time monitoring data, uses devices such as temperature sensors, pressure sensors and wind flow sensors to monitor the operating state of the heat pump in real time, and obtains key data (such as operating temperature, fan state and defrosting conditions); step S200 data is fed back to the heat pump control system to help determine the current state (normal operation, shutdown or need to defrost). Significance: Dynamic monitoring of the heat pump system is achieved so that it can respond to different operating conditions in a timely manner and ensure that the equipment works in the best performance state; the intelligence of the system is improved to provide accurate basic data for subsequent decision-making and avoid non-optimal operation caused by changes in the external environment. Step S300: Adjust the shutter opening angle. Under normal operation of the heat pump, the shutter opening angle is automatically adjusted to optimize the way air flows into the heat exchanger and enhance the heat exchange efficiency; when the heat pump is shut down, powered off or enters the defrosting state, an instruction is issued to automatically close the protective device to protect the heat pump and save energy. Significance: Adjust the air volume according to the specific operating conditions to ensure the effective use of heat and prevent heat loss, thereby improving the overall energy efficiency of the heat pump; through the automatic closing device, energy consumption in unnecessary situations is avoided, the equipment is protected and the service life of the equipment is extended; the shutters are automatically closed and reopened. When the heat pump reaches the defrosting condition, the shutters are automatically closed to prevent the low-temperature air outside from directly contacting the heat exchanger, greatly reducing the heat loss during defrosting; after defrosting is completed, when the relevant conditions are detected, the shutters are reopened to resume normal operation. Significance: It improves the efficiency of the heat pump during the defrosting process, ensures heat retention, reduces energy consumption, and improves the overall energy efficiency of the system; through intelligent control, it avoids the impact of human factors on the operating efficiency of the equipment, and ensures the efficient and stable operation of the heat pump under different working conditions.
[0063] In this embodiment, when the heat pump is operating normally, the protective device is fully opened to the most suitable opening angle originally designed. When the heat pump is shut down or powered off, the protective device is automatically closed. When the heat pump reaches the defrosting condition and turns off the fan, the protective device is turned off. The heat pump performs defrosting in the closed state. Since the protective device isolates the contact between the heat exchanger and the low-temperature air flowing outside, it avoids additional heat loss during defrosting, greatly improving the defrosting efficiency; when the heat pump reaches the condition to exit defrosting and turns on the fan again, the protective device returns to the fully open state and continues to operate normally.
[0064] Compared with the existing technology, this embodiment reduces heat loss during defrosting, improves defrosting efficiency, and reduces system energy consumption; shortens defrosting time and reduces defrosting power consumption; improves defrosting effect, and due to small heat loss, defrosting effect is better and defrosting is more thorough, which improves the reliability of the unit under harsh working conditions; improves the uniformity of air volume during normal operation of the heat pump, improves heat pump efficiency, and reduces non-uniformity of frosting. Compared with the existing technology, this embodiment not only improves the operating efficiency of the heat pump, but more importantly, greatly reduces the heat loss during the defrosting process, and improves the overall operating efficiency of the heat pump.
[0065] In summary, the three steps of this embodiment maximize the efficiency of the heat pump system and reduce unnecessary energy consumption through precise monitoring, intelligent control and optimized management mechanism. At the same time, by strengthening the self-regulation ability of the equipment, the operating reliability and economic benefits of the entire system are improved, achieving the purpose of improving the energy efficiency of the heat pump.
[0066] Example 2: Figure 2 As shown, based on Example 1, the monitoring data acquisition process provided by the embodiment of the present invention includes the following steps:
[0067] S101: Obtain target requirements of monitoring data, analyze the target requirements, and obtain specific types of content corresponding to the target requirements; perform three-dimensional modeling on the heat pump, obtain result position coordinates corresponding to the target requirements according to the three-dimensional modeling, and map the position coordinates with the target requirements to form a relationship mapping table;
[0068] S102: searching for a device corresponding to a specific type in a database according to a relationship mapping table, and obtaining performance parameters of the device; using the location coordinates as a unique identifier to distinguish the location of the device, and adding the performance parameters and coordinates of the device to the relationship mapping table to correspond to the target requirements;
[0069] S103: All devices are associated to form a monitoring data collection network to summarize the content of the monitoring data; the monitoring data collection network issues a startup instruction according to the preset collection cycle of the monitoring data, all devices begin to initialize and collect the corresponding monitoring data, and the location coordinates and monitoring data are packaged and sent to the heat pump, and the controller determines the status of the heat pump.
[0070] The working principle and beneficial effects of the above technical solution are as follows: this embodiment first obtains the target demand of the monitoring data, analyzes the target demand, and obtains the specific type of content corresponding to the target demand; performs three-dimensional modeling on the heat pump, obtains the result position coordinates corresponding to the target demand according to the three-dimensional modeling, maps the position coordinates with the target demand, and forms a relationship mapping table; secondly, searches the database for the device corresponding to the specific type according to the relationship mapping table, and obtains the performance parameters of the device; uses the position coordinates as a unique identifier to distinguish the position of the device, and adds the performance parameters and coordinates of the device to the relationship mapping table, corresponding to the target demand; finally, all devices are associated to form a monitoring data acquisition network to summarize the content of the monitoring data; the monitoring data acquisition network issues a start-up instruction according to the preset acquisition cycle of the monitoring data, all devices start to initialize, and collect the corresponding monitoring data, and packages the position coordinates and monitoring data and sends them to the heat pump, and the controller determines the status of the heat pump. Step S101 of the above scheme obtains the target demand of monitoring data, and clarifies the data types (such as temperature, pressure, wind flow, etc.) required for different monitoring tasks by analyzing the target demand of monitoring; establishes a three-dimensional model of the heat pump to provide basic support for the positioning and spatial identification of subsequent monitoring data; maps the target demand with the corresponding monitoring result position coordinates, generates a relationship mapping table, and forms a clear data processing framework. Significance: It provides a systematic method to clarify the monitoring content and target demand, laying the foundation for subsequent data acquisition; three-dimensional modeling provides an intuitive view, which helps to efficiently identify the required monitoring location and ensure the accuracy of monitoring data; the relationship mapping table effectively connects the relationship between the target demand and the actual monitoring equipment, and enhances the maintainability and scalability of the system. Step S102 searches for devices and performance parameters, and uses the relationship mapping table to quickly search for monitoring devices and their performance parameters that match the specific type of requirements in the database; uses the location coordinates as the unique identifier to distinguish the location of the device, so that the monitoring device has clarity in the network; associates the performance parameters of the device and its coordinates with the target demand to enhance the relevance and accuracy of the data. Significance: Realize dynamic identification and data integration of devices to ensure effective use and information update of each device in the monitoring system; clarify the geographical location of the device to achieve accurate data collection and provide a basis for subsequent data analysis; integrate the performance parameters of the device in the relationship mapping table to provide data support for the optimization of system operation, which is helpful for the decision-making and control of the overall system. Step S103 forms a monitoring data acquisition network. By associating all monitoring devices, a complete monitoring data acquisition network is formed to enhance the coordination and data sharing capabilities of the system; issue a start-up instruction according to the set time period to ensure that all devices initialize and collect data at the appropriate time node; package the collected monitoring data and its location coordinates and send them to the heat pump. The controller can instantly judge the status of the heat pump based on the received data and make corresponding adjustments.Significance: An efficient monitoring network has been built to enhance the real-time and responsiveness of the system, while ensuring comprehensive collection of monitoring data; regular data collection ensures that the operating status of the heat pump is always under monitoring, expanding preventive maintenance management capabilities; the real-time feedback mechanism provides effective data support for the optimal control of the heat pump, enabling the system to maintain optimal performance under different operating conditions.
[0071] In summary, the acquisition process of monitoring data in this embodiment forms a complete closed loop from demand analysis to device search to data collection and transmission, ensuring real-time, accurate and comprehensive monitoring of the heat pump system. It effectively improves the intelligence level and operation efficiency of the system and lays a solid foundation for subsequent control and optimization.
[0072] Example 3: Figure 3 As shown, based on Example 1, the process of determining the state of the heat pump provided in the embodiment of the present invention includes the following steps:
[0073] S201: Implementing the controller to receive real-time data from the temperature sensor, the pressure sensor and the air flow sensor to form a multi-dimensional data packet; the data packet includes key information such as the operating temperature, the fan status, the ambient temperature and the compressor pressure; obtaining multiple groups of thresholds set by the heat pump, the thresholds are used to define normal operation, shutdown and defrosting conditions;
[0074] S202: comparing the key information of the data packet with an item corresponding to the multiple groups of thresholds, and obtaining the status content of the heat pump according to the comparison result;
[0075] Among them, the normal operating state is judged, when the monitored temperature, pressure and air flow are all within the threshold range, and the fan is working normally (for example, the fan operating frequency is within the set range), the controller determines that the heat pump is in a normal operating state;
[0076] Shutdown state recognition: when the temperature is lower than the set minimum threshold, the compressor pressure falls back to a safe range (for example, lower than the static pressure threshold), or the fan state is detected as abnormal (such as stalled), the controller immediately determines that the heat pump is in shutdown state;
[0077] Defrost condition detection: when the temperature sensor detects frost on the evaporator surface and records a specific temperature (e.g. below 0°C), and the air flow sensor detects that the air flow rate drops to a too low range (which may indicate that frost causes poor air flow), the controller makes a real-time judgment and issues a command to enter the defrost state;
[0078] S203: Feedback the judgment result to the controller of the heat pump, and execute corresponding actions according to the program set inside the controller; after each data collection, the controller cross-verifies the operating status and obtains the reliability of the operating status through data trend analysis.
[0079] The working principle and beneficial effects of the above technical solution are as follows: This embodiment first realizes that the controller receives real-time data from temperature sensors, pressure sensors and air flow sensors to form a multi-dimensional data packet; the data packet contains key information such as operating temperature, fan status, ambient temperature and compressor pressure; multiple groups of thresholds set by the heat pump are obtained, and the thresholds are used to define normal operation, shutdown and defrost conditions; secondly, according to the key information of the data packet, a comparison is performed with an item corresponding to the multiple groups of thresholds, and the status content of the heat pump is obtained according to the comparison results; among them, the normal operating status is judged, when the monitored temperature, pressure and air flow are all within the threshold range, and the fan is working normally (for example, the fan operating frequency is within the set range), the controller determines that the heat pump is in normal operating state; shutdown state Identification: When the monitored temperature is lower than the set minimum threshold, the compressor pressure falls back to a safe range (for example, lower than the static pressure threshold), or the fan status is detected as abnormal (such as stalling), the controller immediately determines that the heat pump is in a shutdown state; defrost condition detection: When the temperature sensor detects frost on the evaporator surface and records a specific temperature (for example, lower than 0°C), and the air flow sensor detects that the air flow rate drops to a too low range (which may indicate that frost causes poor air flow), the controller makes a real-time judgment and issues an instruction to enter the defrost state; finally, the judgment result is fed back to the heat pump controller, and the corresponding action is executed according to the program set inside the controller; after each data collection, the controller cross-verifies the operating status and obtains the reliability of the operating status through data trend analysis. Step S201 of the above scheme enables the controller to receive sensor data. The controller can simultaneously receive real-time data information from temperature sensors, pressure sensors and air flow sensors to form a complete multi-dimensional data packet; integration makes the monitoring information more comprehensive, covering all key factors affecting the operating status of the heat pump; the data packet contains key parameters such as operating temperature, fan status, ambient temperature and compressor pressure, providing the necessary basis for status judgment; multiple sets of thresholds set by the heat pump are obtained.

Step S203 feedback and cross-validation, timely feedback the judgment results to the heat pump controller, the controller can quickly perform corresponding operations (such as adjusting the fan speed, starting defrosting, etc.) according to the judgment results, and realize real-time control; after each data collection, the controller confirms the operating status through a cross-validation mechanism, combined with trend analysis, it can identify potential problems that may occur during long-term operation. Significance: An efficient feedback mechanism can ensure that the heat pump automatically adjusts during operation, reduce human intervention, and improve the system's adaptability and operational safety; through cross-validation and trend analysis, the system's ability to identify different failure modes is enhanced, providing a guarantee for the long-term stable operation of the equipment, reducing maintenance costs, and extending the service life of the equipment.

[0096] S201213: After each rule execution, a feedback program is designed to write the execution results into the database, including timestamp, operation results, energy efficiency and user feedback; a data record table is constructed to save the execution history; when multiple rules can be triggered under the same condition, the effective rule is determined according to the set priority.
[0097] The working principle and beneficial effects of the above technical solution are as follows: In this embodiment, the data source of all heat pump operations is first determined, and the data format JSON or XML standard is established to unify the data units; the rules are classified according to the usage scenario, environmental conditions and operation mode, and the priority is set for each rule according to the actual impact; secondly, an object is created for each rule in the rule library, including the rule ID, description, and trigger condition (Example 1 Rule description is "When the indoor temperature is lower than 20°C, start the heating mode", and the trigger condition is "Indoor temperature <20°C"; the rule description is "When the external humidity is greater than 60%, enable the dehumidification mode", and the trigger condition is "External humidity>60%; the rule description is "If the device If the cumulative running time exceeds 500 hours, a maintenance reminder will be issued, and the trigger condition is "equipment running time>500 hours") and an execution action; in the rule implementation, a programming interface is used to extract data related to key information from the database, and a database view is used to integrate all relevant data into one view; when the trigger condition is met, the relevant data will be automatically pulled from the database and the relevant rules will be executed; finally, after each rule execution, a feedback program is designed to write the execution results into the database, including timestamps, running results, energy efficiency, and user feedback; a data record table is constructed to save the execution history; when multiple rules can be triggered under the same condition, the effective rule is determined according to the set priority. Step S201211 of the above scheme determines the data source and establishes standards, fully identifies various data sources required for the operation of the heat pump (such as environmental sensors, user behavior, and meteorological data, etc.), and ensures the comprehensiveness and diversity of data collection; a unified JSON or XML format is used to enable data to be seamlessly transmitted and used between different systems. The unified format reduces the complexity of data analysis and processing; the unification of all data units (for example, temperature is in degrees Celsius, humidity is in percentage, etc.) avoids errors caused by inconsistent units in calculations and rule applications, and improves data consistency and reliability; the rules are classified according to usage scenarios and conditions, making the rule base more organized; in addition, by setting priorities for the rules, it ensures that the system can select the optimal rules in a timely manner in complex situations and optimize the decision-making process. Significance: By clarifying the data source and establishing unified standards, data quality is guaranteed and the maintainability and reliability of the system are improved; the classification and priority setting of rules lay the foundation for subsequent automated decision-making, enabling the system to flexibly respond to complex scenarios and ensure efficient operation and user comfort.Step S201212 creates rule objects and data extraction mechanisms, creates an object for each rule (including rule ID, description, trigger condition, and execution action), forms a clear rule base structure, and facilitates management, search, and execution; realizes dynamic data extraction through the programming interface (API) for the database, so that data can be updated in real time and applied to rule execution, improving the flexibility and response speed of the system; uses database views to integrate related data, realizes one-stop data access, reduces repeated queries and data redundancy, and makes rule execution more efficient; establishes a trigger mechanism, automatically pulls data from the database and executes the corresponding rules when the conditions are met, and ensures timely and accurate execution of the rules. Significance: By creating rule objects and efficient data extraction mechanisms, the system can achieve real-time monitoring and intelligent decision-making; not only improves the efficiency of heat pump operation, but also optimizes energy management, reduces the user's operating burden, and improves user experience. Step S201213 Feedback mechanism and conflict management: after each rule is executed, the execution results (including timestamp, operation results, energy efficiency and user feedback, etc.) are written into the database through the feedback program to form a data closed loop and realize real-time monitoring; a data record table is constructed to save the execution history, providing a basis for subsequent data analysis and rule optimization, and enhancing the traceability of the system; when multiple rules can be triggered at the same time, the effective rules are determined according to the set priority to avoid conflicts and make the system run more stable. Significance: The implementation of the feedback mechanism enables the system to continuously learn and optimize, and adjust the rules according to the actual operation effect; adaptability enables the system to maintain excellent performance in a constantly changing environment and user needs, and at the same time, through the accumulation of execution history records, it provides data support for future optimization decisions.
[0098] In summary, this embodiment can achieve more intelligent, efficient and adaptive operation management through systematic data management, standardized rule base construction, real-time data extraction and feedback mechanism construction. It not only improves the energy efficiency and user experience of the heat pump, but also lays a solid foundation for future system optimization and intelligent development.
[0099] Example 7: Figure 7 As shown, based on Example 5, the process of processing real-time monitoring data provided by the embodiment of the present invention includes the following steps:
[0100] S201221: Use data streams to continuously acquire new data and match it with the rules in the database; use fuzzy logic matching to compare the environmental conditions captured in the real-time data stream with the conditions in the rule base; determine the rules that meet the conditions and form a dynamic threshold combination;
[0101] S201222: Compare the real-time environmental parameters (such as the current indoor temperature, external temperature, humidity, etc.) with the conditions in the rule base, combine all the rules that meet the conditions, and form a new dynamic threshold set; use the currently collected real-time data to determine the current state, including key indicators such as energy consumption and indoor environmental comfort;
[0102] S201223: Generate adjustment suggestions based on feedback information according to real-time status. If the outside temperature drops suddenly, it is recommended to increase the indoor target temperature by 1-2°C. Compare the real-time monitoring data with the historical highest / lowest energy consumption data to evaluate whether the current operating efficiency is within an acceptable range. If deviations are found, determine whether the operating mode needs to be changed, and recommend that users make certain settings during a certain period of time.
[0103] The working principle and beneficial effects of the above technical solution are as follows: the present embodiment firstly utilizes the data stream to continuously acquire new data and matches it with the rules in the database; according to the environmental conditions captured in the real-time data stream, fuzzy logic matching is used to compare with the conditions in the rule base; the rules that meet the conditions are determined and form a dynamic threshold combination; secondly, the real-time environmental parameters (such as the current indoor temperature, external temperature, humidity, etc.) are compared with the conditions in the rule base, and all the rules that meet the conditions are combined to form a new dynamic threshold set; the current state is determined using the currently collected real-time data, including key indicators such as energy consumption and comfort of the indoor environment; finally, adjustment suggestions are generated based on the real-time state using feedback information. If the external temperature drops sharply, it is recommended to increase the indoor target temperature by 1-2°C; the real-time monitoring data is compared with the historical highest / lowest energy consumption data to evaluate whether the current operating efficiency is within an acceptable range. If deviations are found, it is determined whether the operating mode needs to be changed, and it is recommended that the user make certain settings during a certain period of time. Step S201221 of the above scheme is real-time data acquisition and rule matching. New data is continuously acquired through data streams to ensure the system's response speed and adaptability, and to reflect environmental changes in a timely manner; data is analyzed so that the system can handle inaccurate or ambiguous inputs and dynamically determine applicable rules. The significance achieved: It can quickly adapt to environmental changes, such as timely adjusting the operating mode when the external temperature rises or falls; ensuring that suitable operating solutions can be found under different environmental conditions, optimizing the performance of the heat pump through dynamic threshold combinations, and effectively improving the operating accuracy and efficiency of the equipment. Step S201222 Dynamic threshold combination formation and status evaluation, real-time environmental parameters and rule base conditions are compared, so that the system can obtain comprehensive operating status, such as energy consumption level, indoor comfort, etc.; the rules that meet the conditions are integrated to generate a personalized dynamic threshold set that is more in line with the current environment and user needs. Significance achieved: By comprehensively evaluating the current state, the system can more accurately understand the actual situation of the equipment operation, and then combine reasonable operation thresholds to further improve the operation efficiency; users can maintain extremely low energy consumption in a more comfortable environment; for example, at low external temperatures, the system can self-adjust to maintain the indoor temperature without the need for frequent manual adjustments by the user. Step S201223 Feedback information generation and user setting suggestions. Based on the comparison of real-time data and historical energy consumption data, the system can generate scientific adjustment suggestions, such as increasing the indoor target temperature by 1-2℃; evaluate the current operation efficiency through historical data, and if deviation is found, the operation mode can be reasonably adjusted. Significance achieved: Not only can it respond to the external environment in real time, but it can also continuously evaluate and adjust the operation mode to ensure that the equipment works at the highest energy efficiency, which has a direct saving effect on the user's energy cost; through intelligent recommendations, users can enjoy a comfortable indoor environment without too much intervention, and the system can actively adjust to adapt to different usage scenarios, thereby greatly improving the convenience and satisfaction of users.
[0104] In summary, this embodiment has efficient adaptive capabilities and intelligent decision-making capabilities, and can continuously optimize the operation mode of the heat pump based on comprehensive analysis of real-time and historical data. It not only improves the system operation efficiency, reduces energy consumption and user management costs, but also improves the user's living comfort, and promotes the development of smart homes and environmental protection goals.
[0105] Example 8: Figure 8 As shown, based on Example 1, the switching control process of the blinds provided by the embodiment of the present invention includes the following steps:
[0106] S301: Obtaining a target state of the heat pump being in normal operation, shutdown, or requiring defrosting, and calling a corresponding shutter control program according to the target state. The shutter control program is closed and opened, and opening is to adjust the opening angle of the shutter to 60°;
[0107] S302: When the instruction is for normal operation, the servo motor is controlled by the PWM signal to drive the shutter to adjust the opening angle to 60°; when the instruction is for shutdown or defrosting is required, the controller issues a shutter closing instruction, and the servo motor closes the shutter; in the shutdown state, the shutter is completely closed (0 degrees), and when defrosting is required, the shutter is quickly closed;
[0108] S303: Check the temperature and humidity regularly to confirm whether the defrosting operation is completed. When the temperature returns to the normal range (>5°C) and the humidity is lower than 50%, it is marked as defrosting completed. The controller sends a reopening instruction to the blinds and adjusts the blinds through the servo motor. The blinds opening angle is automatically adjusted according to the wind speed and the outside temperature.
[0109] The working principle and beneficial effects of the above technical solution are as follows: the present embodiment first obtains the target state of the heat pump being in normal operation, shutdown or in need of defrosting, and according to the target state, calls the corresponding shutter control program, the shutter control program is closed and opened, and the opening angle of the shutter is adjusted to 60°; secondly, when the instruction is the adjustment during normal operation, the servo motor is controlled by the PWM signal to drive the shutter to adjust the opening angle to 60°; when the content of the instruction is the shutdown state or defrosting is required, the controller issues a shutter closing instruction, and the servo motor closes the shutter; the shutter is completely closed (0 degrees) in the shutdown state, and the shutter is quickly closed when defrosting is required; finally, the temperature and humidity are regularly checked to confirm whether the defrosting operation is completed, and when the temperature returns to the normal range (>5°C) and the humidity is lower than 50%, it is marked as defrosting completion; the controller issues a reopening instruction to the shutter, and adjusts the shutter through the servo motor; the shutter opening angle is automatically adjusted according to the wind speed and the outside temperature, and if the outside temperature rises rapidly or the wind speed is too high, the opening angle is reduced. Step S301 of the above scheme obtains the target state of the heat pump, calls the corresponding blinds control program, and monitors the operating state of the heat pump (normal, shutdown, defrost) to ensure that the system can accurately understand the current requirements; according to different target states, the system can call the corresponding control program to lay the foundation for subsequent operations. Significance: It can flexibly adapt to different working conditions and adjust the state of the blinds according to needs, which enhances the intelligence level of the system; by timely adjusting the switch state of the blinds, it helps the heat pump achieve the best energy efficiency, ensures that the performance is maximized, and reduces energy consumption. Step S302 PWM signal controls the servo motor to realize the opening and closing of the blinds. Through the PWM (pulse width modulation) signal, the movement of the servo motor can be accurately controlled to adjust the blinds opening angle to the set 60° or completely closed (0°); when it is necessary to stop or defrost, the servo motor can respond to the control command quickly to ensure that the blinds are closed quickly, improving the system's ability to cope with changes. Significance: In the shutdown or defrosting state, quickly closing the shutters can protect the heat pump equipment and prevent the negative impact of external cold air on the system, thereby extending the service life of the equipment; by reasonably adjusting the shutter opening angle, the indoor temperature can be effectively managed to ensure the comfort of the indoor environment and meet user needs. Step S303 confirms whether the defrosting operation is completed and adjusts the shutters, regularly checks the temperature and humidity, and realizes real-time monitoring of the defrosting operation process to ensure that the defrosting is completed in time under appropriate environmental conditions; dynamically adjusts the shutter opening angle according to the external environment (such as wind speed and temperature) to adapt to environmental changes and optimize the heat exchange effect. Significance: By monitoring the temperature and humidity status, the efficiency of the defrosting operation is ensured, and the normal operation of the heat pump is restored in time, thereby improving the operating efficiency of the overall system; dynamically adjusting the system status reflects the system's ability to adapt to environmental changes and improves the intelligence level of the heat pump system under different weather and load conditions.
[0110] In summary, this embodiment is used for regulating and controlling the heat pump and blinds to ensure the safety, flexibility and energy efficiency of the system; it not only improves the operating stability of the equipment, but also creates a good environmental comfort for users, while enabling the system to achieve intelligent self-regulation under different environmental conditions.
[0111] Example 9: Fig. 9 As shown, based on Example 8, the process of automatically adjusting the shutter opening angle according to the wind speed and the outside temperature provided in the embodiment of the present invention includes the following steps:
[0112] S3031: Determine the impact of the current external environment on the shutter opening angle through a logical judgment model, and set a corresponding response strategy based on the combination of wind speed and temperature, including:
[0113] High temperature and low wind speed (temperature>25℃&wind speed<1m / s): Set the shutter opening angle to 80° to promote the entry of cold air into the room;
[0114] High temperature and high wind speed (temperature>25℃&wind speed>3m / s): adjust the shutter opening angle to 30° to reduce the direct impact of external wind speed and maintain indoor comfort;
[0115] Low temperature, any wind speed (temperature < 5°C): shutters closed to 0° to prevent cold air from penetrating and keep warm air;
[0116] Moderate temperature (5°C to 25°C): dynamically adjust the opening angle (ranging from 30° to 60°) according to wind speed to optimize indoor temperature and air circulation;
[0117] S3032: After calculating the required opening angle, the controller sends a control signal to the servo motor; the position sensor continuously monitors the actual opening angle of the blinds, and if a deviation is found, the controller automatically sends a correction instruction to adjust the blinds to the ideal state;
[0118] S3033: The controller continuously monitors the external environment and internal status, re-evaluates whether the shutter opening angle needs to be adjusted each time the wind speed or temperature changes, and re-evaluates and confirms the status after each adjustment; stores environmental data and corresponding opening angle settings to optimize the control strategy.
[0119] The working principle and beneficial effects of the above technical solution are as follows: This embodiment first determines the impact of the current external environment on the opening angle of the blinds through a logical judgment model, and sets the corresponding response strategy according to the combination of wind speed and temperature, including: high temperature and low wind speed (temperature>25℃&wind speed<1m / s): set the blinds opening angle to 80° to promote the entry of cold air into the room; high temperature and high wind speed (temperature>25℃&wind speed>3m / s): adjust the blinds opening angle to 30° to reduce the direct impact of external wind speed and maintain indoor comfort; low temperature and arbitrary wind speed (temperature<5℃): close the blinds to 0° to prevent cold air from entering and keep warm air ; Moderate temperature (5℃ to 25℃): dynamically adjust the opening angle according to the wind speed (varies between 30° and 60°) to optimize the indoor temperature and air circulation; secondly, after calculating the required opening angle, the controller sends a control signal to the servo motor; the position sensor continuously monitors the actual opening angle of the blinds. If a deviation is found, the controller automatically sends a correction instruction to adjust the blinds to the ideal state; finally, the controller continuously monitors the external environment and internal state, re-evaluates whether the opening angle of the blinds needs to be adjusted every time the wind speed or temperature changes, and performs state evaluation and confirmation after each adjustment; stores environmental data and corresponding opening angle settings to optimize the control strategy. Step S3031 of the above scheme sets the logic judgment model and response strategy. Through the logic judgment model, the system can evaluate the impact of external environmental factors (wind speed and temperature) on the adjustment of the blinds in real time, so as to adopt the corresponding opening angle adjustment strategy; according to different temperature and wind speed combinations, set targeted opening angles to finely manage the indoor climate and avoid the "one size fits all" control method. Significance achieved: By adjusting the opening angle of the blinds, the indoor temperature and air circulation can be effectively managed, the comfort of the living environment can be improved, and the needs of users can be met; ensuring that the external environment is effectively isolated under extreme climatic conditions (such as high temperature and strong wind or low temperature), it helps to reduce the burden on the heating or cooling system, thereby achieving energy conservation and improved utilization efficiency. Step S3032: The control signal is sent to the servo motor and corrected in real time. The controller will generate a control signal based on the calculated ideal opening angle to ensure that the servo motor can accurately adjust the opening angle of the blinds; the actual opening angle is monitored by the position sensor.
