AIROSD Powers a Landmark University Hot Water Project with an Intelligent and Energy-Efficient Heat Pump Solution
In 2026, Hunan University celebrates the centenary of its official naming. With a history spanning more than 1,000 years, this prestigious Chinese university continues to advance education, research and innovation.
At its new Science and Innovation Port Campus, AIROSD has delivered a major Large Scale Heat Pump Project, featuring 142 integrated Air Source Heat Pump units and 58 independent hot water supply systems. With a daily capacity exceeding 750 tons, the project provides reliable hot water for a campus planned to accommodate approximately 20,000 students and faculty members.
By combining high-efficiency Commercial Heat Pump Water Heater technology with intelligent management, this Centralized Hot Water System sets a new example for modern university infrastructure and sustainable campus development.
1. Hunan University: A Long Heritage of Academic Excellence
Hunan University traces its origins to Yuelu Academy, established in 976 AD during the Song Dynasty. Officially named Hunan University in 1926, it has become one of China's distinguished institutions under the 211 Project, 985 Project and Double First-Class initiative.
The new Science and Innovation Port Campus represents an important step in the university's development, providing modern facilities for education, research and innovation.
2. Meeting the Hot Water Demands of a Modern Campus
The new campus covers approximately 1,600 mu (1.07 million m²), with a planned total building area of around one million square meters. Its first phase opened in September 2026, featuring more than 700,000 m² of building area.
Student accommodation includes 16 dormitory buildings across two residential areas. Every dormitory room is equipped with a private bathroom and connected to a centralized hot water supply.
Serving thousands of students requires a reliable School Hot Water System capable of handling significant fluctuations in daily consumption. It must maintain sufficient water pressure and stable temperatures during busy morning and evening periods.
Changsha's cold and humid winters also place higher demands on heating performance and defrosting technology. In addition, the campus layout requires flexible zoning, independent operation and convenient maintenance.
With extensive experience in commercial hot water engineering and educational projects, AIROSD was selected to provide an integrated Air Source Heat Pump solution for the campus.
3. Four Key Advantages of the AIROSD Heat Pump Solution
1) High-Capacity Supply with Modular Design
The project uses 142 integrated Air Source Heat Pump units configured into 58 independent parallel hot water supply systems, delivering more than 750 tons of hot water every day.
This modular configuration allows different campus areas to operate independently. Capacity can be allocated according to actual demand, while individual systems can be maintained without affecting the entire campus supply.
As a flexible Centralized Hot Water System, the solution also supports future campus expansion and simplifies daily operation. The design demonstrates how a Large Scale Heat Pump Project can meet the demanding requirements of a large educational institution.
2) Intelligent Control and Automatic Defrosting
The AIROSD solution integrates intelligent control functions, including automatic start and stop, water temperature regulation, energy consumption monitoring, remote fault alerts and operating data analysis.
The system adjusts its operation according to changing hot water demand, helping improve energy efficiency during both peak and off-peak periods.
Its intelligent defrosting technology supports stable Air Source Heat Pump operation in Changsha's cold and humid winter climate. Centralized monitoring also makes it easier for operators to track equipment status, water temperature and system performance, reducing manual inspections and maintenance workload.
3) Reliable Hot Water Supply Throughout the Day
For university dormitories, a dependable hot water supply is essential to students' everyday comfort.
The AIROSD School Hot Water System is designed to provide hot water around the clock while maintaining stable temperatures and water pressure, including during periods of high demand.
Through independent zoned supply and coordinated operation, the Centralized Hot Water System helps reduce common problems such as insufficient pressure in distant buildings and temperature fluctuations caused by changing consumption.
The result is a more comfortable and reliable hot water experience for students throughout the year.
4) Energy Efficiency for a Greener Campus
An Air Source Heat Pump extracts thermal energy from ambient air to heat water, offering an energy-efficient alternative to conventional electric resistance and fossil-fuel-based water heating.
The high-efficiency Commercial Heat Pump Water Heater equipment used in this project is designed to reduce energy consumption and associated carbon emissions. With no on-site fuel combustion, low-noise operation and intelligent energy management, the system contributes to a cleaner campus environment.
This Large Scale Heat Pump Project demonstrates how advanced heat pump technology can support universities in improving energy efficiency and advancing sustainable infrastructure.
