Project Implementation

项目实施

1. This project considers the different energy needs and patterns of campus buildings, and based on the design principles of "comfort, energy efficiency, and reliability", solves the energy needs of the campus through multi-dimensional technology integration. Select a green zero carbon valley energy storage system for heating swimming pools and gyms; The ultra-high energy efficiency multi energy complementary system is used for cold and hot supply in school hospitals, express stations, and boiler rooms, as well as constant temperature in swimming pools; Screw chiller (heat pump) unit is used for cooling in summer sports venues; Electric steam generator+high-efficiency thermal storage water tank is used for heating and storing domestic hot water.

实施方案与过程：项目结合校园建筑不同用能需求和规律，依据“舒适性、节能性、可靠性”设计原则，通过多维度技术集成解决校园用能需求。选定绿色零碳谷电储能系统为游泳馆、体育馆供暖；超高能效多能互补系统为校医院、快递站及锅炉房提供冷热联供与泳池恒温；螺杆冷水（热泵）机组用于夏季体育馆制冷；电蒸汽发生器+高效蓄热水箱用于生活热水加热与储存。

2. In addition, to create a green and zero carbon campus, the hot water heating source will be renovated based on the existing resources and conditions of the school. The implementation plan is as follows. The high-temperature hot water used in student life adopts the technical route of electric steam generator+energy storage type water thermal storage, using low valley electricity to store heat in the water tank, achieving peak shaving effect (after on-site investigation, it was found that there were pipeline pressure drops and the original water tank no longer had the conditions for thermal storage use. A new thermal storage water tank needs to be built for use).

为创建绿色零碳校园，基于学校现有资源与条件改造热水加热热源，具体方案：学生生活用高温热水采用电蒸汽发生器+储能型水蓄热技术路线，利用低谷电储热调峰（经现场勘察，原有管道存在压降、原有水罐不具备蓄热条件，需新建蓄热水箱）。

3. The original heat exchange system for the swimming pool water heating and swimming tube shower in the swimming pool is recommended to be transformed into an ultra-low temperature air source heat pump unit to supplement the heat lost by the swimming pool water (air source constant temperature swimming pool). The shower water in the swimming pool can use the technology route of heating domestic water.

游泳馆泳池水加热及淋浴原有换热系统，改造为超低温空气源热泵机组补充泳池水散失热量（空气能恒温泳池），游泳馆淋浴用水采用生活水加热技术路线。

4. The current hot water for students' bathing is stored in a 280m³ water tank. It is recommended to use the existing water tank in conjunction with an ultra-low temperature air source heat pump unit, that is, to transform the route to ultra-low temperature air source heat pump+water thermal storage technology.

学生现有洗浴热水采用280立方米水箱储存，改造路线为超低温空气源热泵+水蓄热技术，利用原有水箱配合机组使用。

5. The hot water demand for the cafeteria's logistics is for 5 independent dishwashing sinks, with a daily water consumption of approximately 2 cubic meters per sink. The recommended renovation plan is to have 5 sets of independent water storage systems and Hot Bida.

食堂后勤热水需求覆盖5处独立洗碗槽（每日每处用水量约2立方米），改造方案为五套独立水蓄热系统+热必达。

6. The above work runs through the entire process of project design, construction, operation, and maintenance.

以上工作贯穿项目设计-施工-运行-维护全过程。

7. Before the implementation of the project, the original heating method was gas boilers. Apart from the most concerning safety issues, from an economic perspective, it has high energy consumption and no energy-saving advantages. In terms of heating effect, the water supply is small and the temperature fluctuates greatly. By collaborating with both parties to create the Liaoning University Green Zero Carbon Comprehensive Energy Project, the construction of this project truly achieves zero pollution and emissions, and plays a significant role in promoting urban environmental protection; It is conducive to creating a comprehensive smart zero carbon campus, promoting the process of urban systematization and efficiency, returning the city to a blue sky, and creating a happy and livable city.

实施前后对比：实施前，原供热方式为燃气锅炉，存在安全隐患，能耗大且无节能优势，供水量小、温度波动大；实施后，项目实现无污染、零排放，推动城市环境保护，助力打造智慧零碳校园，推进城市系统化、高效化进程。

8. The successful operation of the project has completely solved the safety hazards of gas boiler energy consumption in schools, and built a "Double First Class 211 Zero Carbon University" to help campuses achieve carbon neutrality goals ahead of schedule, realizing the first demonstration comprehensive energy industry university research training base in Liaoning Province, and providing a research platform for efficient energy storage and comprehensive energy technology application in the fields of carbon peak and carbon neutrality in various universities in Liaoning Province. At the same time, it saves more than 5 million yuan in natural gas special procurement costs for the school every year.

项目成功运行彻底解决学校燃气锅炉用能安全隐患，助力建设“双一流211零碳高校”，推动校园提前完成碳中和目标，实现辽宁省首个示范性综合能源产学研实训基地落地，为省内高校相关领域研究提供平台，每年节省天然气采购费用500余万元。

9. During the implementation of the project, due to the unique business format, the large number of personnel on campus, and the complex heating demand and system, there were numerous challenges faced from design to construction, including difficult to solve weather and transportation issues. Relevant personnel from the unit developed solutions based on solid professional skills. During the operation and maintenance phase, the unit actively assisted the operation and maintenance personnel in communicating with the school, achieving the construction of a benign ecosystem of two-way travel between project personnel and users.

实施挑战与应对：项目实施过程中，因校园业态特殊、人员密集、供热需求与系统复杂，面临天气、交通运输等多重挑战，单位相关人员凭借扎实专业技术定制解决方案；运行与维护阶段，积极协助运维人员与校方沟通，构建项目人员与用户双向奔赴的良性生态。

Project Impact & Sustainability

项目影响力、可推广性与可持续性

The 14th Five Year Plan period is a critical period for China to embark on a new journey of building a socialist modernized country in all respects and advancing towards the second centenary goal after achieving the goal of building a moderately prosperous society in all respects and realizing the first centenary goal. It is a new path of high-quality development guided by ecological priority and green development, and to achieve new and greater development.

“十四五”时期是我国全面建成小康社会后，开启全面建设社会主义现代化国家新征程的关键时期，走好以生态优先、绿色发展为导向的高质量发展新路子意义重大。

Currently, China's economy is still in a stage of rapid development. To achieve "carbon neutrality", it is necessary to consider the energy efficiency of industry and electricity, as well as the use of renewable energy, from the perspective of emissions. For a considerable period of time, China's new energy still needs to maintain a high-speed development trend, continuously expand its application scale, alleviate cost and consumption contradictions, and gradually demonstrate the role of clean substitution.

当前中国经济仍处于高速发展阶段，实现“碳中和”需从排放端提升工业和电力能源效率、扩大可再生能源使用。未来较长一段时间内，我国新能源需维持高速发展趋势，扩大应用规模，缓解成本及消纳矛盾，逐步发挥清洁替代作用。

As a leading force in science, technology, and culture in a country, universities aim to build their campuses into zero carbon comprehensive energy campuses that integrate multiple energy sources such as electricity, heat, cold, and gas, with a focus on "source network load storage". They are not only practitioners and drivers of "carbon peak and carbon neutrality", but also laboratories for the comprehensive energy transformation of university scientific and technological achievements and theoretical models for "carbon peak and carbon neutrality" calculations.

大学作为国家科技、文化的排头兵，打造电、热、冷、气等多种能源协同互济、“源网荷储”的零碳综合能源校园，既是“碳达峰、碳中和”的践行者与推动力，也是大学科技成果转化的综合能源实验室和“碳达峰、碳中和”计算理论模型，具有重要示范与推广价值。
