The integrated energy management system for industrial buildings can monitor electricity consumption, water consumption, gas consumption, cooling capacity, and heating capacity of industrial buildings, while fully meeting and improving the functional requirements of the buildings. It aims to reduce energy consumption and improve energy utilization efficiency, rather than simplifying the functional requirements of the buildings or lowering their functional standards.
I. System Introduction
An integrated energy management system for industrial buildings can monitor electricity consumption, water consumption, gas consumption, cooling capacity, and heating capacity, including lighting, air conditioning, and power. It aims to reduce energy consumption and improve energy efficiency while fully meeting and improving building functional requirements, rather than simplifying functional requirements or lowering functional standards. By establishing an energy management system, it generates a real-time, dynamic, scientific, and accurate energy monitoring database and statistical analysis results, providing a scientific basis for energy-saving retrofitting decisions based on policies, regulations, and standards. Accelerating technological progress, strengthening supervision and management, utilizing renewable energy, and enhancing energy management in industrial buildings can reduce energy consumption while improving building functionality.
II. System Composition
The energy management system mainly consists of "on-site energy consumption data acquisition and control equipment", "network communication layer", "energy consumption data server" and "energy management and control system platform".
III. System Functions
By analyzing the characteristics of energy-consuming equipment through the integrated energy management platform software for industrial buildings, and adding appropriate retrofit equipment, equipment performance can be improved, power efficiency increased, and raw material loss reduced. Rational scheduling of maintenance based on equipment operating history can effectively increase safe operating time and reduce maintenance costs. Setting alarm parameters ensures timely alerts for unstable equipment operation, guaranteeing safe operation. Centralized monitoring, measurement, control, and management of system energy enables real-time and historical data storage, querying, analysis, and statistical analysis, achieving automated energy management. Fully utilizing real data as the basis for energy-saving operation analysis avoids human error, helps the system strengthen energy consumption and energy accounting management, and makes system management more scientific.
1. Energy consumption statistics
The system offers multiple data statistics methods, including statistics by region, energy consumption type, and equipment type. It provides statistical analysis for various time periods, such as daily, weekly, monthly, and yearly. The system outputs reports in various formats, including Excel and TXT, and allows direct printing. It also provides various graphical representations, such as line charts, bar charts, and pie charts, which can be saved as documents and printed. Energy consumption statistics include HVAC, lighting, power, gas, water, heating, cooling, fuel oil, and electricity. It can also consider collecting ambient temperature and humidity data, as well as regional carbon dioxide levels, as references for energy consumption analysis.
2. Energy Consumption Analysis
The system offers various analysis algorithms, such as year-on-year comparison, comparison by month, and ranking, enabling analysis of regional energy consumption, specific energy consumption types, and equipment type energy consumption. Analysis periods include daily, weekly, monthly, and yearly analysis, as well as data analysis within any specified time period. Analysis results can be printed and saved in two or more document formats, and also offer printing and saving in three graphical formats: line charts, bar charts, and pie charts.
3. Energy consumption assessment
The system establishes multiple energy consumption assessment standards, such as building energy density standard values, building energy consumption rating standards, and equipment operation status rating standards. Assessment conclusions are drawn by comparing the actual energy consumption of buildings with these standards. The system can periodically assess the total energy consumption level of buildings, regional sub-items of energy consumption, and equipment energy consumption status. Assessment cycles can be daily, weekly, monthly, or yearly. Assessment results should provide corresponding document outputs, including text descriptions, tables, and various graphs to illustrate the energy consumption status. Assessment results can specifically identify areas, energy types, and equipment with abnormal energy consumption, and propose preliminary solutions to address the causes of the abnormalities, thereby improving the efficiency of energy-saving renovation work. Energy consumption assessment results can be automatically generated and saved in a common document format, and can be printed and exported. All historical records are saved in a historical database and cannot be deleted without permission.
4. Energy consumption alarm
The system can be pre-set with abnormal energy consumption limits and monitors all energy consumption data points within the building in real time without operator intervention. Alarms are categorized into several levels, alerting management personnel according to their urgency. When an alarm occurs, the system should record detailed information, accompanied by screen flashing and audible alerts. Operators can view specific information such as location, energy consumption type, time, and abnormal values by querying alarm events. Alarm events can be set to be sent to designated management personnel via SMS, email, etc.
5. Log query
The system can display various information such as energy consumption exceeding limits, abnormalities, and alarm records for equipment in each energy-consuming unit at different times. The energy consumption assessment results must support printing in report form and saving in multiple document formats. Report settings can be customized by the user, and the customized design interface must provide a graphical editing window and drag-and-drop functionality. Import and export functions should be provided for the configured reports.
