However, there is currently no unified standard for energy efficiency grading and evaluation of high-efficiency refrigeration room systems applicable nationwide.

[0003] my country has a vast territory, with vastly different meteorological conditions across different regions. To ensure the applicability and rationality of the proposed energy efficiency indicators for refrigeration room systems across different cities nationwide, it is necessary to conduct a grading and zoning study on the energy efficiency of refrigeration room systems. To improve the energy efficiency of building energy systems and reduce building energy consumption, the "Energy Conservation Standard for Public Buildings" (GB50189-2015) has established zoning requirements for building envelope thermal performance and air conditioning system energy efficiency in each building thermal zone.

[0056] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0057] The method for determining the energy efficiency classification of a refrigeration room system based on the average wet-bulb temperature provided in this application can be applied to Figure 1The illustrated application environment includes an energy management platform 102 and multiple refrigeration plant systems 104. Energy management platform 102 is connected to each of these refrigeration plant systems 104. These refrigeration plant systems 104 correspond to multiple cities within multiple thermal zones and represent the cooling capacity of a building within that city during the cooling season. For example, they represent the central air conditioning system in an office building in Shanghai. Energy management platform 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart car devices. Portable wearable devices can include smart watches, smart bracelets, and head-mounted devices.

[0058] In one embodiment, Figure 2 As shown in the figure, a method for determining the energy efficiency rating of a refrigeration room system based on the average wet bulb temperature is provided. Figure 1 The energy management platform in the example is used to illustrate the following:

[0059] S101: Obtain the average wet-bulb temperature value of each city included in the current thermal zone in its respective cooling season.

[0060] Thermal zoning is a division of more than 270 cities across the country based on the dry-bulb temperature of the climate. It is generally divided into five thermal zones: the hot summer and warm winter zone, which includes cities such as Shenzhen, Nanning, Haikou, and Yangjiang. The hot summer and cold winter zone, which includes cities such as Shanghai, Chongqing, Hefei, and Nanjing. The mild zone, which includes cities such as Guiyang, Kunming, Tengchong, and Xichang. The cold zone, which includes cities such as Beijing, Taiyuan, Xi'an, and Tianjin. The severely cold zone, which includes cities such as Harbin, Urumqi, Xining, Changchun, and Shenyang. The wet-bulb temperature is the air temperature with humidity. The average wet-bulb temperature during the cooling season is the average hourly wet-bulb temperature of each city during the cooling season. Taking Harbin as an example, it is the average hourly wet-bulb temperature of Harbin from June to September.

[0061] In this embodiment, the energy management platform can collect the hourly wet-bulb temperature values ​​of each city in each thermal zone during the cooling season from the meteorological bureau's information platform through big data collection. The energy management platform then calculates the average wet-bulb temperature values ​​of each city in each thermal zone during the cooling season. Alternatively, the energy management platform can directly obtain the hourly wet-bulb temperature values ​​of each city during the cooling season from a professional meteorological database. The energy management platform then calculates the average wet-bulb temperature values ​​of all cities in each thermal zone. It should be noted that different cities have different cooling seasons. For example, Hainan's cooling season is from May to November, and Hefei's cooling season is from June to September.

[0062] S102 , calculating energy efficiency ratio values ​​of refrigeration room systems of different levels corresponding to each city based on environmental information of each city during its cooling season.

[0063] The environmental information includes at least one of wet-bulb temperature distribution, climate conditions, building volume, and building type. The energy efficiency ratio value of the refrigeration room system corresponding to each city is used as a standard for measuring the energy efficiency grading of the refrigeration room system corresponding to each city.

[0064] In this embodiment, taking the current thermal zone as an example, since the average wet-bulb temperature values ​​of each city in the current thermal zone during its respective cooling seasons correspond to the power consumption values ​​of the refrigeration room systems of each city during the cooling seasons, that is, the higher the wet-bulb temperature value, the lower the power consumption values ​​of the refrigeration room systems of each city during the cooling seasons; the lower the wet-bulb temperature value, the greater the power consumption values ​​of the refrigeration room systems of each city during the cooling seasons. Therefore, the energy management platform can determine the power consumption values ​​of the refrigeration room systems of each city during the cooling seasons based on the corresponding relationship between the average wet-bulb temperature values ​​of each city during the cooling seasons and the power consumption values ​​of the refrigeration room systems of each city during the cooling seasons, and then calculate the energy efficiency ratio values ​​of the refrigeration room systems corresponding to each city based on the power consumption values ​​of the refrigeration room systems of each city during the cooling seasons. It should be noted that in actual applications, the energy management platform can pre-record the correspondence between the average wet-bulb temperature value of each city in its respective cooling season and the power consumption value of the refrigeration room system of each city in the cooling season in a mapping table. That is, the energy management platform can directly obtain the power consumption value of the refrigeration room system of each city in the cooling season based on the average wet-bulb temperature value of each city in its respective cooling season by querying the above mapping table.

[0065] S103 , dividing the current thermal zone into regions according to the energy efficiency ratio values ​​of the refrigeration room systems corresponding to each city, to obtain at least two target sub-regions.

[0066] Among them, cities in the same target sub-area use the same energy efficiency level.

[0067] In this embodiment, the current thermal zone can be divided into two or more target sub-zones based on demand. Taking the division of the current thermal zone into two target sub-zones as an example, an energy efficiency ratio threshold value can be pre-set, and cities whose refrigeration room systems have an energy efficiency ratio value less than or equal to the energy efficiency ratio threshold value can be divided into one target sub-zone, and cities whose refrigeration room systems have an energy efficiency ratio value greater than the energy efficiency ratio threshold value can be divided into another target sub-zone. Alternatively, an algorithm can be used to divide cities whose refrigeration room systems have similar energy efficiency ratio values ​​into one target sub-zone, and other cities into another target sub-zone.

[0068] S104: Determine the energy efficiency rating of the refrigeration room system corresponding to each city included in each target sub-area.

[0069] In this embodiment, the energy efficiency grade of the refrigeration room system corresponding to each city included in each target sub-area is determined based on the energy efficiency ratio value of the refrigeration room system corresponding to each city included in each target sub-area; optionally, the energy efficiency grade of the refrigeration room system corresponding to each city included in each target sub-area can also be determined based on the average wet-bulb temperature value of each city included in each target sub-area during the respective cooling season; optionally, the energy efficiency grade of the refrigeration room system corresponding to each city included in each target sub-area can also be determined based on the energy efficiency ratio value of the refrigeration room system corresponding to each city included in each target sub-area and the average wet-bulb temperature value of each city included in each target sub-area during the respective cooling season. When performing specific grading, the energy efficiency grading of the refrigeration room systems corresponding to the cities included in each target sub-area can be divided into different levels. The higher the level, the more energy-efficient the refrigeration room systems corresponding to the cities included in each target sub-area. For example, the energy efficiency grading of the refrigeration room systems corresponding to the cities included in each target sub-area can be divided into Class A, Class B, and Class C, or the energy efficiency grading of the refrigeration room systems corresponding to the cities included in each target sub-area can be divided into the highest standard level, the middle level, and the lowest standard level.

[0070] The above-mentioned method for determining the energy efficiency rating of a refrigeration room system based on average wet-bulb temperature obtains the average wet-bulb temperature values ​​for each city included in the current thermal zone during its respective cooling season. Based on the environmental information of each city during its respective cooling season, the energy efficiency ratio values ​​of the refrigeration room systems corresponding to different grades in each city are calculated. The current thermal zone is then divided into at least two target sub-zones based on the energy efficiency ratio values ​​of the refrigeration room systems corresponding to the cities. The energy efficiency rating of the refrigeration room systems corresponding to each of the target sub-zones is then determined. The environmental information includes at least one of wet-bulb temperature distribution, climate conditions, building volume, and building type. The above-mentioned method for determining the energy efficiency rating of a refrigeration room system based on average wet-bulb temperature obtains meteorological parameters for each city included in the current thermal zone, calculates loads based on building type, and uses energy efficiency ratio values ​​to divide each thermal zone into multiple target sub-zones. This method overcomes the problem of unreasonable and inaccurate energy efficiency rating evaluation of refrigeration room systems caused by overly large thermal zones, thereby improving the rationality and accuracy of energy efficiency rating evaluation of refrigeration room systems.

[0071] In one embodiment, the present application also provides a specific implementation method of the above-mentioned "dividing the current thermal zone into regions according to the energy efficiency ratio value of the refrigeration room system corresponding to each city to obtain at least two target sub-regions", such as Figure 3Shown, including:

[0072] S201: Divide the current thermal zone into preset areas to obtain at least two preset sub-areas.

[0073] Each preset sub-area includes a refrigeration room system corresponding to at least one preset city.

[0074] In this embodiment, the current thermal zone can be divided into two preset sub-zones, three preset sub-zones, or more, based on actual needs. The more preset sub-zones there are, the more reasonable and accurate the energy efficiency rating standards for the refrigeration room systems corresponding to the cities included in each target sub-zone are. Specifically, when dividing the preset areas, the energy management platform can divide the different preset sub-zones by setting partition boundaries within the current thermal zone. Specifically, the energy management platform can first arrange the energy efficiency ratio values ​​of all cities within the current thermal zone in ascending order. Optionally, if the current thermal zone is divided into two preset sub-zones, the energy efficiency ratio value at the 1 / 2 position is selected as the partition boundary to divide the current thermal zone into two preset sub-zones, namely Zone I and Zone II. If the current thermal zone is divided into three preset sub-zones, the energy efficiency ratio values ​​at the 1 / 3 position and the 2 / 3 position are selected as the partition boundaries to divide the current thermal zone into three preset sub-zones, namely Zone I, Zone II, and Zone III. It should be noted that the partition boundary can be determined by the number of preset sub-zones.

[0075] S202 : Determine the energy efficiency ratio deviation rate of the refrigeration room system corresponding to each preset city included in each preset sub-area according to the energy efficiency ratio value of the refrigeration room system corresponding to each city.

[0076] Among them, the energy efficiency ratio deviation rate is the standard for pre-setting the thermal zone division.

[0077] In this embodiment, after the energy management platform obtains the energy efficiency ratio value of the refrigeration room system corresponding to each preset city contained in each preset sub-area based on the aforementioned S102 method, it then calculates the average energy efficiency ratio value of the refrigeration room system corresponding to all preset cities contained in the preset sub-area, and performs a ratio operation on the energy efficiency ratio value of the refrigeration room system corresponding to each preset city contained in each preset sub-area and the average energy efficiency ratio value of the refrigeration room system corresponding to all preset cities contained in the preset sub-area to obtain the energy efficiency ratio deviation rate of the refrigeration room system corresponding to each preset city contained in the preset sub-area.

[0078] S203: Determine at least two target sub-areas in the current thermal zone according to the energy efficiency ratio deviation rate of the refrigeration room system corresponding to each preset city included in each preset sub-area and a preset deviation rate threshold.

[0079] Among them, the preset deviation rate threshold is used to measure the difference between the energy efficiency ratios of the refrigeration room systems corresponding to each preset city included in each preset sub-area. The preset deviation rate threshold can be determined in advance by the energy management platform according to the division requirements, and the preset deviation rate threshold is related to the number of target sub-areas. For example, if two target sub-areas are divided, the preset deviation rate threshold can be optimally set to 10%. If three target sub-areas are divided, the preset deviation rate threshold can be optimally set to 6% or 8%.

[0080] In this embodiment, when the energy management platform obtains the energy efficiency deviation rate of the refrigeration room system corresponding to each preset city contained in each preset sub-area, the energy efficiency deviation rate of the refrigeration room system corresponding to each preset city can be further compared with the preset deviation rate threshold in turn, and based on the comparison result, it is determined whether the preset sub-area in the current thermal zone is the target sub-area in the current thermal zone. If so, the preset sub-area contained in the current thermal zone is directly used as the target sub-area in the current thermal zone. If not, it is necessary to re-divide the preset sub-area in the current thermal zone, and then re-determine the target sub-area in the current thermal zone.

[0081] Optionally, a specific implementation of the above S203 is provided, such as Figure 4 As shown, the method includes:

[0082] S301: The first preset sub-area among all preset sub-areas is used as the current preset sub-area.

[0083] In this embodiment, when the energy management platform divides the current thermal zone into preset areas based on the aforementioned step S201 and obtains at least two preset sub-areas, the first preset sub-area among all the preset sub-areas can be first analyzed as the current preset sub-area. For example, the current thermal zone is divided into two preset sub-areas, namely, Zone I and Zone II, with Zone I serving as the current preset sub-area. The current thermal zone is divided into three preset sub-areas, namely, Zone I, Zone II and Zone III, with Zone I serving as the current preset sub-area.

[0084] S302, traverse the refrigeration room systems corresponding to each preset city in the current preset sub-area in turn, and determine whether the energy efficiency ratio deviation rate of the refrigeration room system corresponding to each preset city is less than or equal to the preset deviation rate threshold; if the energy efficiency ratio deviation rate of the refrigeration room system corresponding to each preset city in the current preset sub-area is less than or equal to the preset deviation rate threshold, execute step S303; if in the process of traversing the refrigeration room systems corresponding to each preset city in the current preset sub-area, traversing to the refrigeration room system corresponding to the preset city whose energy efficiency ratio deviation rate is greater than the preset deviation rate threshold, execute step S304.

[0085] S303: The next preset sub-area among all the preset sub-areas is used as the current preset sub-area, and the process returns to executing the step of traversing the refrigeration room systems corresponding to the preset cities in the current preset sub-area until the traversal of the refrigeration room systems corresponding to the preset cities in all the preset sub-areas is completed, and at least two preset sub-areas are obtained and determined as at least two target sub-areas; and the energy efficiency ratio deviation rate of the refrigeration room system corresponding to each city in each target sub-area is less than or equal to the preset deviation rate threshold.

[0086] S304: Re-divide the current thermal zone into preset areas to obtain at least two new preset sub-areas, and return to the step of determining the energy efficiency ratio deviation rate of the refrigeration room system corresponding to each preset city contained in each preset sub-area based on the energy efficiency ratio value of the refrigeration room system corresponding to each city.

[0087] In this embodiment, the current thermal zone is divided into two target sub-zones as an example for explanation. When the refrigeration room systems corresponding to the preset cities in the current preset sub-zone are traversed in sequence, the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the current preset sub-zone is compared. Two scenarios will appear. The first scenario is: if the first energy efficiency ratio deviation rate is less than or equal to the preset deviation rate threshold, the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the second city is compared. If the second energy efficiency ratio deviation rate is less than or equal to the preset deviation rate threshold, the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the third city is compared. And so on, until the energy efficiency ratio deviation rates of the refrigeration room systems corresponding to all cities in the current preset sub-zone are traversed, and the energy efficiency ratio deviation rates of the refrigeration room systems corresponding to the first city in the current preset sub-zone are compared. The energy efficiency ratio deviation rates of the refrigeration room systems corresponding to all cities in the preset sub-area are less than or equal to the preset deviation rate threshold, indicating that the current division of the preset sub-area is reasonable. In this case, the above method can be continued to start comparison from the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the next preset sub-area until the energy efficiency ratio deviation rates of the refrigeration room systems corresponding to all cities in the next preset sub-area are traversed, and the energy efficiency ratio deviation rates of the refrigeration room systems corresponding to all cities in the next preset sub-area are less than or equal to the preset deviation rate threshold, indicating that the current division of the preset sub-area is reasonable. In this case, the two preset sub-areas pre-divided in the current thermal engineering zone can be used as the two target sub-areas in the final current thermal engineering zone.

[0088] The following example illustrates the method for determining the target sub-area in the second scenario:

[0089] Example 1: Assume that the current thermal engineering zone includes 10 cities, and the current thermal engineering zone is divided into two preset sub-zones. If the zone boundary line is set at 1 / 2, each preset sub-zone includes 5 cities. Specifically, the first preset sub-zone is first used as the current preset sub-zone. If the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the current preset sub-zone is greater than the preset deviation rate threshold, or if the energy efficiency ratio deviation rate of the refrigeration room system corresponding to a certain city in the traversal is greater than the preset deviation rate threshold, it means that the division of the current preset sub-zone is incorrect, then the zone boundary line is moved from 1 / 2 to the next city, that is, the zone boundary line is moved to the 6th city. Then the first preset sub-zone includes 6 cities, and the second preset sub-zone includes 4 cities are included, and then the first preset sub-area is used as the current preset sub-area. The above method is continued to be used to start the comparison from the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the current preset sub-area. After the energy efficiency ratio deviation rate of the refrigeration room system corresponding to all cities in the current preset sub-area is traversed, and the energy efficiency ratio deviation rate of the refrigeration room system corresponding to all cities in the current preset sub-area is less than or equal to the preset deviation rate threshold, it means that the division of the current preset sub-area is reasonable. In this case, the above method can be continued to start the comparison from the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the next preset sub-area. If the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the current preset sub-area is greater than the preset deviation rate threshold value, or if the energy efficiency ratio deviation rate of the refrigeration room system corresponding to a certain city is greater than the preset deviation rate threshold during the traversal, it means that the division of the current preset sub-area is incorrect, then the partition boundary line is moved from 1 / 2 to the previous city, that is, the partition boundary line is moved to the 5th city. However, since the preset sub-area divided with the 5th city as the partition boundary line is incorrect, the partition boundary line is moved forward to the 4th city to form a new preset sub-area, that is, the first preset sub-area includes 4 cities, and the second preset sub-area includes 6 cities.

In this case, the two preset sub-areas pre-divided in the current thermal zone can be used as the two target sub-areas in the final current thermal zone.

[0090] Example 2: Assume that the current thermal engineering zone includes 9 cities, and the current thermal engineering zone is divided into three preset sub-zones. If the first zone boundary line is set at 1 / 3 and the second zone boundary line is set at 2 / 3, then each preset sub-zone includes 3 cities. Specifically, first take the first preset sub-zone as the current preset sub-zone. If the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the current preset sub-zone is greater than the preset deviation rate threshold, or if the energy efficiency ratio deviation rate of the refrigeration room system corresponding to a certain city appears during the traversal and is greater than the preset deviation rate threshold, it means that the division of the current preset sub-zone is incorrect, then the first zone boundary line is moved from 1 / 3 to the next city, that is, the first zone boundary line is moved to the 4th city, then the first preset sub-zone includes There are 4 cities, the second preset sub-area includes 2 cities, and the third preset sub-area includes 3 cities. Then, the first preset sub-area is used as the current preset sub-area, and the above method is continued to be used to start the comparison from the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the current preset sub-area. After the energy efficiency ratio deviation rates of the refrigeration room systems corresponding to all cities in the current preset sub-area are traversed, and the energy efficiency ratio deviation rates of the refrigeration room systems corresponding to all cities in the current preset sub-area are less than or equal to the preset deviation rate threshold, it means that the division of the current preset sub-area is reasonable. In this case, the above method can be continued to be used to start the comparison from the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the second preset sub-area. If the first city in the current preset sub-area If the energy efficiency ratio deviation rate of the refrigeration room system corresponding to a city is greater than the preset deviation rate threshold, or if the energy efficiency ratio deviation rate of the refrigeration room system corresponding to a certain city is greater than the preset deviation rate threshold during the traversal, it means that the division of the current preset sub-area is incorrect, then the second partition boundary line is moved from 2 / 3 to the next city, that is, the second partition boundary line is moved to the 7th city to form a new preset sub-area, that is, the first preset sub-area includes 4 cities, the second preset sub-area includes 3 cities, and the third preset sub-area includes 2 cities. Continue to follow the above method and use the first preset sub-area as the current preset sub-area until the energy efficiency ratio deviation rates of the refrigeration room systems corresponding to all cities in the current preset sub-area are traversed, and the energy efficiency ratio deviation rates of all cities in the preset sub-area are greater than the preset deviation rate threshold. The energy efficiency ratio deviation rate of the refrigeration room system is less than or equal to the preset deviation rate threshold, indicating that the current preset sub-area division is reasonable. In this case, the above method can be continued to start comparison from the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the third preset sub-area. If the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the current preset sub-area is greater than the preset deviation rate threshold, or the energy efficiency ratio deviation rate of the refrigeration room system corresponding to a certain city in the traversal is greater than the preset deviation rate threshold, indicating that the current preset sub-area division is incorrect, the second partition boundary line is moved from the 7th city to the 6th city. Since the preset sub-area divided with the 6th city as the second partition boundary line is incorrect, the partition boundary line is moved forward.Move to the 5th city to form a new preset sub-area, that is, the first preset sub-area includes 4 cities, the second preset sub-area includes 1 city, and the third preset sub-area includes 4 cities. Continue to follow the above method and use the first preset sub-area as the current preset sub-area until the energy efficiency ratio deviation rate of the refrigeration room system corresponding to all cities in the current preset sub-area is traversed, and the energy efficiency ratio deviation rate of the refrigeration room system corresponding to all cities in the preset sub-area is less than or equal to the preset deviation rate threshold, indicating that the division of the current preset sub-area is reasonable. In this case, you can continue to compare the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the second preset sub-area according to the above method until the energy efficiency ratio deviation rate of the refrigeration room system corresponding to all cities in the second preset sub-area is traversed. The energy efficiency ratio deviation rate is less than or equal to the preset deviation rate threshold for the refrigeration room systems of all cities in the second preset sub-area, indicating that the current division of the preset sub-area is reasonable. In this case, the above method can be continued to be used to compare the energy efficiency ratio deviation rate of the refrigeration room system corresponding to the first city in the third preset sub-area, until the energy efficiency ratio deviation rate of the refrigeration room system corresponding to all cities in the third preset sub-area is traversed, and the energy efficiency ratio deviation rate of the refrigeration room system corresponding to all cities in the third preset sub-area is less than or equal to the preset deviation rate threshold, indicating that the current division of the preset sub-area is reasonable.
