2019–2026: AIROSD Heat Pump Passes a 7-Year Endurance Test at Yili Normal University
“Seven years ago, we made the right decision. Today, the warmth is still the same.”— Project Manager of Yili Normal University Hot Water Project
Located in Xinjiang, Yili experiences long winters, strong winds, frost, and temperatures below -20°C. Such harsh weather creates severe challenges for outdoor heating equipment. Since 2019, AIROSD Air source heat pump units installed at Yili Normal University have continued operating stably in this extreme climate, completing a remarkable seven-year endurance test.
Reliable Air Source Heat Pump Solution for Student Dormitories
In 2019, Yili Normal University planned to improve student living conditions and solve hot water supply problems in dormitories. Traditional coal boilers were phased out due to environmental protection policies, while electric boilers created high operating costs. Conventional water heaters frequently failed during freezing winters. After careful evaluation, the university selected AIROSD Air source heat pump technology as the final solution.
The project mainly adopted a high-efficiency Hot water heat pump system specially designed for ultra-low-temperature environments. As an advanced Air source heat pump solution, the Hot water heat pump can continuously provide stable domestic hot water even under extremely cold conditions. Compared with conventional heating systems, the Hot water heat pump delivers better energy efficiency, lower operating costs, and more reliable performance.
Besides the Hot water heat pump product line, AIROSD also manufactures Swimming pool heat pump, Ground source heat pump, and Drying heat pump systems for different applications. A Swimming pool heat pump is ideal for maintaining constant swimming pool temperatures in hotels, villas, and schools. A Ground source heat pump uses underground geothermal energy for highly efficient heating and cooling. A Drying heat pump is widely used in agricultural drying, industrial drying, and food processing industries. However, for the cold climate conditions in Yili, the Air source heat pump based Hot water heat pump system proved to be the best choice.
Advanced Hot Water Heat Pump Technology for Extreme Cold Areas
Yili Normal University has over 25,000 students and staff members, creating concentrated hot water demand every day. The project adopted a BOT business model, allowing the university to complete installation without major initial investment.
AIROSD equipped the project with ultra-low-temperature Air source heat pump units featuring EVI vapor injection technology and intelligent rapid defrosting technology. The Hot water heat pump system can maintain outlet water temperatures above 55°C during severe winters.
Unlike ordinary equipment, this Hot water heat pump was specially developed for cold regions. The system effectively solves common problems such as insufficient heating capacity and repeated frosting in low-temperature environments. If a Swimming pool heat pump had been selected for this dormitory hot water application, it would not have matched the operating requirements. A Ground source heat pump would have required expensive underground drilling and complex construction work. A Drying heat pump is specifically designed for drying applications and cannot provide domestic hot water.
Therefore, the Air source heat pump based Hot water heat pump system became the most reliable and economical solution for the university project.
Seven Years of Stable Operation
Over the past seven years, the AIROSD Hot water heat pump system has helped the university save significant energy costs. Through the intelligent control platform, students can enjoy stable hot water supply 24 hours a day.
During a recent inspection visit, AIROSD engineers confirmed that the Air source heat pump units still operate smoothly with very little performance decline. The equipment casing remains in excellent condition, while the compressors continue stable operation after years of service.
Most importantly, the Hot water heat pump system has not caused any major water supply interruption due to equipment failure during the past seven years. This achievement fully demonstrates the long-term reliability and durability of AIROSD Air source heat pump technology in extremely cold climates.
At the same time, AIROSD Swimming pool heat pump products have been widely used in university swimming pools and hotel pool projects across southern China. Ground source heat pump systems have shown excellent performance in campus heating projects in northern regions. Drying heat pump equipment has also been successfully applied in agricultural product drying, seafood drying, fruit drying, and industrial drying applications.
Each product line has its own professional application:
Air source heat pump systems provide efficient heating and cooling solutions.
Swimming pool heat pump systems maintain stable swimming pool temperatures.
Ground source heat pump systems utilize renewable geothermal energy.
Hot water heat pump systems provide reliable domestic hot water supply.
Drying heat pump systems offer energy-saving drying technology.
AIROSD Heat Pump Solutions Serve More Than 300 Schools
AIROSD has provided professional heating and hot water solutions for more than 300 schools and universities across China. Following the successful Yili project, AIROSD has also completed multiple Hot water heat pump projects in Xinjiang vocational colleges and public institutions.
For more than 2,555 days and nights, AIROSD Air source heat pump units have continued operating reliably in freezing temperatures below -20°C. Stable operation is the best proof of product quality.
In the future, AIROSD will continue expanding its five major product lines, including Air source heat pump, Swimming pool heat pump, Ground source heat pump, Hot water heat pump, and Drying heat pump systems, providing energy-saving, environmentally friendly, and intelligent heating solutions for schools, commercial buildings, hotels, factories, and industrial projects worldwide.
