One 、 Analysis of energy use in Colleges and universities

At present, there are the following problems in the use of energy in Colleges and universities ：

First, the demand for energy is increasing ： With the rapid development of colleges and Universities , Number of energy users on campus 、 Energy consuming equipment 、 The building area increases year by year , The demand for energy is also rising . The objective contradiction between the increasing demand for energy consumption and the task of energy conservation and consumption reduction , It increases the difficulty of energy management and energy conservation and consumption reduction .

Second, the construction of energy-saving team is weak ： One side , The current work of energy conservation and consumption reduction in Colleges and universities is basically undertaken by the logistics support department , All energy consuming units are seriously absent in the work of energy conservation and consumption reduction , Failed to build a reasonable management team for energy conservation and consumption reduction ; On the other hand , Energy saving and consumption reduction teams are generally lack of technical personnel and skill training .

Third, the investment in energy conservation is insufficient ： First , The core work of the campus lies in scientific research and education , Investment in energy conservation is relatively weak . Secondly, most old campuses have serious aging of energy supply and energy consumption equipment , The popularity of energy-saving technologies and products is not high . then , It is about the allocation of energy measuring instruments , Failed to popularize all secondary energy consumption , Some measuring instruments are backward , It seriously restricts the energy consumption data collection 、 Statistics 、 Analysis and utilities recovery , As a result, it is impossible to supervise the whole process of energy use .

Four The management mode needs to be optimized ： Most colleges and universities still bear the cost of using energy , As a result, the pressure of energy conservation and consumption reduction is concentrated in schools , All energy using units and individuals lack responsibility for energy conservation and consumption reduction , There is “ Big pot rice ” The phenomenon , There is no corresponding incentive and restraint mechanism , As a result, the teachers, students and staff do not have a strong sense of responsibility for energy conservation and consumption reduction .

5、 ... and Energy saving awareness To be improved ： Current school “ When people walk, the lights go out , Turn off the water ” And other energy-saving habits have not been formed .“ The long light ”、“ Long running water ”、 No one reported the damage of water and electricity facilities 、 The air conditioner is still used when the temperature is appropriate or the air conditioner is not turned off when leaving 、 There are many phenomena such as office equipment standing by all year round .

According to the actual situation of the above schools , In order to achieve the goal of building energy conservation , Master the real-time data of building energy consumption in Colleges and universities , It is very important to do a good job in energy consumption statistics , So , structure Campus comprehensive energy efficiency platform be necessary .

3、 ... and 、 Function introduction of energy efficiency platform

 

Comprehensive data : A comprehensive display of the campus energy consumption , Including abnormal alarm conditions （ Data exception / The equipment is abnormal ）、 water 、 Energy consumption of electricity and other energy sources 、 campus 3D Model customization 、 And can join the dynamic display of campus energy consumption data .

Integrated power consumption monitoring ： On campus 35KV-10KV-0.4KV Energy consumption at all levels shall be monitored and analyzed ; Monitor and analyze incoming power quality and key laboratory power quality ; Monitor and alarm the environment in the power transformation and distribution room ; Be able to monitor the transformer , Ensure power safety and stability .

Integrated water monitoring ： The total water inflow of all buildings covering the campus shall be measured at one level ; The water inflow of a single building shall be measured at two levels . Individual experimental buildings are subject to three-level measurement monitoring . Through one level 、 Second level 、 Real time analysis of water balance with three-level water meter measurement data , When there is abnormal water condition, it can send an alarm immediately .

business / Dormitory prepayment ： Use water for all kinds of shops on campus 、 Use electricity for prepayment management . Control the power consumption of students' dormitories at fixed time 、 Use monitoring and prepayment management of illegal electrical appliances .

Air conditioning energy conservation supervision ： It can monitor the energy consumption of air conditioners and monitor and control the power consumption of split air conditioners .

street lamp / Intelligent lighting supervision ： Realize the power monitoring and lighting control of indoor lighting and outdoor street lighting , Automatic management or remote group control management can be carried out according to the preset logic .

Analysis of campus energy consumption ： Energy consumption supervision can be realized 、 Energy consumption query 、 Energy consumption alarm 、 Energy consumption publicity 、 Energy consumption audit and other functions , Can help the school clear 、 Get a direct understanding of energy consumption , And assist the school to do a good job of audit publicity .

Campus energy consumption analysis report ： Be able to use energy for the whole 、 Overall monitoring and measuring equipment working status 、 Year on year data 、 Data analysis based on month on month data , Help the school to understand the comprehensive energy efficiency of the campus .

Integrated mobile terminal ： Relevant personnel can log in to the energy management and control system at any time through the mobile client , Realize the measurement of various energy systems in the school 、 monitoring 、 control 、 State feedback 、 Alarm and other functions , Carry out real-time supervision on energy consumption such as campus water and electricity .

 

 

 

Four 、 Energy efficiency platform system topology

5、 ... and 、 Conclusion

Colleges and universities shoulder the responsibility of education 、 A base for scientific research and social service , It is an important community that constitutes the society , It is also a big consumer of resources and energy , Build an energy-saving supervision system on campus , It can give full play to the role of the school in teaching and educating people , Cultivate students' sense of responsibility for energy conservation and emission reduction , Establish a sense of thrift . As students leave school , Go to work , It can also bring the concept of energy conservation and emission reduction into the society , Become one by one “ Energy saving ” seeds , Contribute to the national energy conservation and emission reduction work . therefore , The construction of campus comprehensive energy efficiency platform not only has important practical significance for building an energy-saving society , It has far-reaching educational significance .
