Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration cabinet management, and in particular to a control method for an energy-saving composite refrigeration cabinet with intelligent wide-range temperature control. Background Art

[0002] A freezer is another name for a refrigerator or freezer. All evaporator tubes in high-quality freezers are made of high-quality copper coils, processed into wide, custom-shaped surfaces. Stainless steel plates have a smooth, even surface and uniform thickness. Choosing the right thickness ensures both a long service life and a smooth, durable appearance for the freezer. Copper tubes transfer heat better than aluminum or composite tubes and offer greater corrosion resistance. High-quality copper coils offer high internal cleanliness and fewer joints, effectively preventing leaks or blockages in the refrigeration system. Rectangularizing the round tubes shifts the contact between the evaporator tube and the cooling liner from point to surface, expanding the transfer area and accelerating cooling.

[0003] Energy-saving composite refrigeration cabinets are high-efficiency refrigeration units that combine energy-saving technologies with innovative designs based on traditional refrigeration cabinets. These refrigeration cabinets are typically used in commercial or domestic environments, especially where food, medicine, or other temperature-controlled products need to be stored for long periods of time.

[0004] Existing energy-saving composite refrigeration cabinets do not have intelligent control. After the energy-saving composite refrigeration cabinet has been running for a period of time, the internal temperature may rise. The energy-saving composite refrigeration cabinet needs to increase the power to reduce the internal temperature. However, the storage of items inside the energy-saving composite refrigeration cabinet does not necessarily require extremely low temperatures. If the time period when the energy-saving composite refrigeration cabinet needs to increase the power coincides with the time period when electricity prices are high, the storage cost of the items will increase.

[0071] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0072] Reference Figure 1 As shown, a control method for an energy-saving composite refrigeration cabinet with intelligent wide-range temperature control includes:

[0073] S100: Based on the remote control terminal, data is read and processed from a storage device of the energy-saving composite refrigeration cabinet to obtain historical operating data of the energy-saving composite refrigeration cabinet;

[0074] S200, analyzing and processing historical operating data of the energy-saving composite refrigeration cabinet based on the remote control terminal to obtain a peak operating time interval of the energy-saving composite refrigeration cabinet;

[0075] S300, analyzing and processing the peak working time interval of the energy-saving composite refrigeration cabinet based on the remote control terminal, and determining a control scheme for the energy-saving composite refrigeration cabinet;

[0076] It can be understood by those skilled in the art that, in the absence of interference from external factors, the temperature increase inside the energy-saving composite refrigeration cabinet follows a certain pattern. When the temperature inside the energy-saving composite refrigeration cabinet rises, in order to lower the temperature inside the energy-saving composite refrigeration cabinet, the energy-saving composite refrigeration cabinet will increase the working power to lower the temperature inside the energy-saving composite refrigeration cabinet. However, the preservation of items inside the energy-saving composite refrigeration cabinet does not necessarily require extremely low temperatures. If the time period when the energy-saving composite refrigeration cabinet increases its working power coincides with the time period of high electricity charges, the storage cost of the items will increase. In order to reduce the storage cost of the items, the operating status of the energy-saving composite refrigeration cabinet is adjusted in real time to avoid the energy-saving composite refrigeration cabinet from running at high power during the time period of high electricity charges. The above method can not only realize the intelligent control of the energy-saving composite refrigeration cabinet, but also effectively reduce the operating cost of the energy-saving composite refrigeration cabinet.

[0077] Reference Figure 2 As shown, based on the remote control terminal, data reading and processing are performed on the storage device of the energy-saving composite refrigeration cabinet to obtain the historical operation data of the energy-saving composite refrigeration cabinet, which specifically includes the following steps:

[0078] S101, obtaining location information of an energy-saving composite refrigeration cabinet;

[0079] S102: The remote control terminal searches the product database based on the acquired location information of the energy-saving composite refrigeration cabinet to acquire data link information of the energy-saving composite refrigeration cabinet;

[0080] S103, the remote control terminal establishes a communication connection with the energy-saving composite refrigeration cabinet according to the data link information of the energy-saving composite refrigeration cabinet;

[0081] S104: Based on the remote control terminal, data is read and processed from a storage device of the energy-saving composite refrigeration cabinet to obtain historical operation data of the energy-saving composite refrigeration cabinet.

[0082] Reference Figure 3 As shown, the remote control terminal retrieves and processes the product database based on the location information of the energy-saving composite refrigeration cabinet, and obtains the data link information of the energy-saving composite refrigeration cabinet, specifically including the following steps:

[0084] S1022. The remote control terminal performs information matching processing in the product database according to the serial number of the energy-saving composite refrigeration cabinet, and obtains the construction document of the energy-saving composite refrigeration cabinet;

[0085] S1023. Based on the remote control terminal, perform information retrieval processing on the construction document of the energy-saving composite refrigeration cabinet to obtain data link information of the energy-saving composite refrigeration cabinet;

[0086] In this embodiment, due to different application scenarios, the models of the installed energy-saving composite refrigeration cabinets may be different. Therefore, the energy-saving composite refrigeration cabinets in different installation locations are numbered to distinguish them. Therefore, it is necessary to determine the number of the energy-saving composite refrigeration cabinet through the location information of the energy-saving composite refrigeration cabinet, and then determine the construction document of the energy-saving composite refrigeration cabinet through the number of the energy-saving composite refrigeration cabinet, and obtain the data link information of the energy-saving composite refrigeration cabinet from the construction document of the energy-saving composite refrigeration cabinet. Finally, the remote control terminal establishes a communication connection with the energy-saving composite refrigeration cabinet through the data link information of the energy-saving composite refrigeration cabinet to realize the reading of the historical operation data of the energy-saving composite refrigeration cabinet.

[0087] Reference Figure 4 As shown, based on the remote control terminal, the historical operation data of the energy-saving composite refrigeration cabinet is analyzed and processed to obtain the working peak time interval of the energy-saving composite refrigeration cabinet, which specifically includes the following steps:

[0088] S201: The remote control terminal classifies and processes the historical operation data of the energy-saving composite refrigeration cabinet based on date, and obtains the daily historical operation data of the energy-saving composite refrigeration cabinet;

[0089] S202: The remote control terminal classifies and processes the daily historical operation data of the energy-saving composite refrigeration cabinet based on the hourly characteristic to obtain the total hourly operating power of the energy-saving composite refrigeration cabinet.

[0090] S203: Based on the remote control terminal, the total working power of the energy-saving composite refrigeration cabinet per hour is determined and processed to obtain the working peak time interval of the energy-saving composite refrigeration cabinet.

[0091] Reference Figure 5 As shown, based on the remote control terminal, the total working power of the energy-saving composite refrigeration cabinet per hour is judged and processed to obtain the working peak time interval of the energy-saving composite refrigeration cabinet, which specifically includes the following steps:

[0092] S2031. Based on the remote control terminal, determine the total hourly operating power of the energy-saving composite refrigeration cabinet and the set power threshold;

[0093] S2032: If the total hourly operating power of the energy-saving composite refrigeration cabinet is greater than or equal to the set power threshold, the energy-saving composite refrigeration cabinet is set to high power operation, and the high power operation time interval is recorded;

[0094] S2033: If the total hourly operating power of the energy-saving composite refrigeration cabinet is less than the set power threshold, the energy-saving composite refrigeration cabinet is output to operate at normal power, and the normal power operation time interval is not recorded;

[0096] S2035: Based on the remote control terminal, determine and process the number of high-power operation time intervals to obtain the working peak time interval of the energy-saving composite refrigeration cabinet.

[0097] Reference Figure 6 As shown, based on the remote control terminal, the number of high-power operation time intervals is judged and processed to obtain the working peak time interval of the energy-saving composite refrigeration cabinet, which specifically includes the following steps:

[0098] S20351. Based on the remote control terminal, determine the number of high-power operation time intervals and the set number threshold;

[0099] S20352: If the number of high-power operation time intervals is greater than or equal to the set number threshold, the energy-saving composite refrigeration cabinet operates at high power during the operation time interval, and the peak operation time interval of the energy-saving composite refrigeration cabinet is recorded;

[0100] S20353: If the number of high-power operation time intervals is less than the set number threshold, the energy-saving composite refrigeration cabinet does not belong to high-power operation in the operation time interval, and the operation time interval is not recorded;

[0101] In this embodiment, if there is no interference from external factors, the increase in the internal temperature of the energy-saving composite refrigeration cabinet conforms to a certain rule, that is, within a time interval, the internal temperature of the energy-saving composite refrigeration cabinet rises by a certain temperature. Therefore, the historical operation data of the energy-saving composite refrigeration cabinet is classified by date and hour to obtain the total working power of the energy-saving composite refrigeration cabinet per hour. Then, the total working power of the energy-saving composite refrigeration cabinet per hour is judged to determine whether the energy-saving composite refrigeration cabinet is operating at high power. It is worth noting that the high-power operation of the energy-saving composite refrigeration cabinet is not necessarily within the peak working time interval of the energy-saving composite refrigeration cabinet. Because, when the user turns on the energy-saving composite refrigeration cabinet, the cold air of the energy-saving composite refrigeration cabinet will overflow, thereby causing the temperature inside the energy-saving composite refrigeration cabinet to rise. In order to reduce the temperature inside the energy-saving composite refrigeration cabinet, the energy-saving composite refrigeration cabinet needs to operate at high power. Therefore, the high-power operation time intervals in the same time interval are counted. When the number of high-power operation time intervals in the same time interval reaches a specified number, the time interval is the peak working time interval of the energy-saving composite refrigeration cabinet.

[0102] Reference Figure 7 As shown, based on the remote control terminal, the peak working time interval of the energy-saving composite refrigeration cabinet is analyzed and processed, and the control scheme of the energy-saving composite refrigeration cabinet is determined, which specifically includes the following steps:

[0103] S301: Obtaining an electricity charging schedule, the remote control terminal analyzes and processes the electricity charging schedule to obtain a high-price electricity charging time period;

[0104] S302: Based on the remote control terminal, determine the high-price electricity charging time interval and the peak working time interval of the energy-saving composite refrigeration cabinet to obtain a determination result;

[0105] S303: The remote control terminal designs a control scheme for the energy-saving composite refrigeration cabinet according to the judgment result.

[0106] Reference Figure 8 As shown, obtaining the electricity charging schedule, the remote control terminal analyzes and processes the electricity charging schedule, and obtaining the high-price electricity charging time interval specifically includes the following steps:

[0107] S3011. Based on the remote control terminal, perform data retrieval processing on the power supply company's database to obtain the electricity charging schedule;

[0108] S3012. Extracting data from the electricity charging schedule based on the remote control terminal to obtain electricity charging standards;

[0109] S3013. Based on the remote control terminal, sort the electricity charging standards to obtain the maximum electricity charge;

[0110] S3014. The remote control terminal matches the electricity charge schedule with the maximum electricity charge value to obtain a high-price electricity charge time interval.

[0111] The specific calculation formula for obtaining the maximum value of the electricity charge is:

[0112]

[0113] Where M max is the maximum value of electricity charge; n is the number of electricity charge standards; M i is the electricity charging standard; max() is the maximum value function.

[0114] Reference Figure 9 As shown, based on the remote control terminal, the high-price electricity charging time interval and the energy-saving composite refrigeration cabinet working peak time interval are judged and processed, and the judgment result is obtained in the following steps:

[0115] S3021. Based on the remote control terminal, determine the high-price electricity charging time interval and the peak working time interval of the energy-saving composite refrigeration cabinet;

[0116] S3022: If the high-price electricity time interval does not coincide with the peak operating time interval of the energy-saving composite refrigeration cabinet, the remote control terminal does not adjust the operating state of the energy-saving composite refrigeration cabinet;

[0117] S3023: If the high-price electricity time period coincides with the peak operating time period of the energy-saving composite refrigeration cabinet, the remote control terminal adjusts the operating state of the energy-saving composite refrigeration cabinet.

[0118] Reference Figure 10 As shown, the remote control terminal designs a control scheme for the energy-saving composite refrigeration cabinet according to the judgment result, which specifically includes the following steps:

[0119] S3031. If the high electricity price period coincides with the peak operating period of the energy-saving composite refrigeration cabinet;

[0120] S3032. Obtain information about all products stored in the energy-saving compound refrigeration cabinet;

[0121] S3033. Based on the remote control terminal, perform data retrieval processing on the relevant information of all products stored in the energy-saving compound refrigeration cabinet to obtain the maximum storage temperature of all products;

[0122] S3034. Based on the remote control terminal, sort the highest storage temperatures of all products to obtain the critical storage temperature;

[0123] S3035. The remote control terminal controls the energy-saving composite refrigeration cabinet to reduce operating power and records the real-time temperature inside the energy-saving composite refrigeration cabinet;

[0124] S3036. Compare and determine the real-time temperature inside the energy-saving composite refrigeration cabinet and the critical storage temperature based on the remote control terminal;

[0125] S3037. If the real-time temperature inside the energy-saving composite refrigeration cabinet is lower than the critical storage temperature, continue to reduce the operating power of the energy-saving composite refrigeration cabinet. When the real-time temperature inside the energy-saving composite refrigeration cabinet equals the critical storage temperature, stop reducing the operating power of the energy-saving composite refrigeration cabinet and record the operating power.

[0126] S3038. If the real-time temperature inside the energy-saving composite refrigeration cabinet is equal to the critical storage temperature, stop reducing the operating power of the energy-saving composite refrigeration cabinet and record the operating power;

[0127] In this embodiment, due to the living habits of users, regional electricity consumption may peak in a certain time period. In order to reduce the load on the distribution network and increase the electricity price during peak hours, so that users can stagger their electricity usage time, data is extracted from the electricity charging timetable to determine the time period with high electricity prices. Then, an intersection analysis is performed on the time period with high electricity prices and the working peak time period of the energy-saving composite refrigeration cabinet to determine whether the working peak time period of the energy-saving composite refrigeration cabinet is within the time period with high electricity prices. If the working peak time period of the energy-saving composite refrigeration cabinet is within the time period with high electricity prices, the working power of the energy-saving composite refrigeration cabinet is adjusted. Because the storage temperatures of the items stored inside the energy-saving composite refrigeration cabinet are different, the maximum storage temperatures of all products are compared and judged to screen out all products. The lowest temperature among the maximum storage temperatures of the product, that is, the maximum temperature at which a product can be stored, that is, the temperature at which all products can be stored, that is, the critical storage temperature. Finally, by reducing the working power of the energy-saving composite refrigeration cabinet, the storage cost of the items can be reduced. However, it is necessary to monitor the temperature inside the energy-saving composite refrigeration cabinet in real time to prevent the real-time temperature of the energy-saving composite refrigeration cabinet from being higher than the critical storage temperature, which may cause damage to the items. When the temperature inside the energy-saving composite refrigeration cabinet is the same as the critical storage temperature, stop reducing the working power of the energy-saving composite refrigeration cabinet, and the energy-saving composite refrigeration cabinet operates at this power, so that the energy-saving composite refrigeration cabinet is always maintained at the critical storage temperature. The above method reduces the working power of the energy-saving composite refrigeration cabinet during the time period when electricity charges are high, which can effectively reduce the electricity operation cost of the energy-saving composite refrigeration cabinet.
