Hot Water Project for Xiangshan Port Senior Technical School, Ningbo
For many boarding schools, bathing during peak hours often means low water pressure, unstable temperature, and long waiting times. At Xiangshan Port Senior Technical School in Ningbo, Zhejiang, this long-standing problem has been completely solved. With a total investment of 529 million yuan, the new campus now serves nearly 4,000 teachers and students with 24-hour constant-temperature hot water. Thanks to its outstanding energy-saving performance, the project was named one of the “2024 Top Ten Landmark Heat Pump Hot Water Projects in the Yangtze River Delta,” becoming a new benchmark for clean-energy campus hot water.
This project fully demonstrates the advantages of an advanced heat pump system. By combining direct heating, circulation, and pressurized water supply, AIROSD created a highly stable and efficient hot water solution for a large-scale school environment. In this project, the Air source heat pump became the core equipment, while the Hot water heat pump function ensured immediate and stable hot water output. At the same time, the Heat pump system was optimized for the concentrated water-use patterns of a boarding school.
Project Overview
The school is located in Xiangshan, Ningbo, and includes four dormitory buildings plus a dining hall serving around 4,000 teachers and students. The project is equipped with 25 sets of AIROSD 10HP Air source heat pump units and adopts five independent direct heating and circulation pressurized heat pump systems. The project was officially put into use in 2024.
This Heat pump system integrates the technical advantages of the Air source heat pump, the Hot water heat pump, the Swimming pool heat pump, and the Ground source heat pump, and has been deeply optimized for campus hot water demand. Although a Swimming pool heat pump is usually designed for constant-temperature circulation, and a Ground source heat pump is often used for building heating and cooling, AIROSD drew on their stable control logic and efficient heat exchange principles to improve the overall performance of this school hot water project.
Why Choose an Air Source Heat Pump?
After multiple rounds of comparison, the school found that the Air source heat pump was more energy-efficient and safer than gas heating and electric heating. The AIROSD solution was selected because it provided a practical and highly efficient Hot water heat pump system that could handle both peak demand and long-term operation.
The direct heating mode of the Air source heat pump heats cold water to a set temperature in one step and delivers it directly to the end users, effectively eliminating temperature fluctuations. The circulation function keeps the pipeline water warm at all times, allowing hot water to be available immediately when the tap is turned on. The pressurized structure ensures balanced hot and cold water pressure, keeping the water supply stable even during peak usage. This Hot water heat pump solution fully solves the traditional problems of weak pressure, unstable temperature, and slow response.
Compared with a Swimming pool heat pump, which focuses more on maintaining constant-temperature circulation, the campus Hot water heat pump must respond to large and sudden water demand. Compared with a Ground source heat pump, which usually requires buried pipe installation and more site conditions, the Air source heat pump is easier to install and has a lower initial investment. For this reason, the Air source heat pump has become the most suitable choice for many school projects.
Efficient and Intelligent Heat Pump System
This Heat pump system is equipped with intelligent control, allowing operation to be started and stopped according to actual demand. As a result, the system achieves more than 30% energy savings overall. The modular design also makes independent maintenance easier, reducing operation and maintenance costs over time.
AIROSD’s Hot water heat pump solution uses standardized and precise installation methods, which improves safety, durability, and long-term stability. The Air source heat pump plays the leading role in the system, while the circulation and pressurization design ensures that the entire Heat pump system can operate smoothly under frequent and concentrated use.
It is worth noting that AIROSD offers a full product line including the Air source heat pump, Hot water heat pump, Swimming pool heat pump, and Ground source heat pump. The Swimming pool heat pump is ideal for constant-temperature water environments, the Ground source heat pump is well suited to large-scale heating and cooling applications, and the Hot water heat pump is particularly effective for schools, dormitories, hotels, and other places with centralized hot water demand. Among them, the Air source heat pump remains the best choice for this campus project.
Results and Recognition
After commissioning, the system fully met the hot water needs of nearly 4,000 teachers and students. The project was honored as one of the “2024 Top Ten Landmark Heat Pump Hot Water Projects in the Yangtze River Delta,” reflecting the strong technical and practical value of the AIROSD solution.
AIROSD has long focused on clean-energy hot water projects for schools and has already served more than 300 educational institutions across China, including prestigious universities such as South China University of Technology and Shandong University. Whether it is a Hot water heat pump for daily campus use, a Swimming pool heat pump for sports facilities, or a Ground source heat pump for large buildings, AIROSD can provide customized solutions based on real project conditions.
Compared with the Ground source heat pump, the Air source heat pump is easier to deploy and more flexible in site selection. Compared with the Swimming pool heat pump, the Hot water heat pump is better suited to high-volume, high-temperature water output. This Heat pump system, centered on the Air source heat pump and supported by direct heating, circulation, and pressurization, has successfully set a new benchmark for campus hot water in the Yangtze River Delta.
In the future, AIROSD will continue to promote innovation in the Air source heat pump, Hot water heat pump, Swimming pool heat pump, Ground source heat pump, and broader Heat pump system applications, providing more schools with energy-saving, safe, stable, and intelligent hot water solutions.
