Air Source Heat Pumps Proven in Challenging Cold and Humid Climates
Guizhou Province, located on the Yunnan-Guizhou Plateau in southwest China, is well known for its cold, humid winters and frequent rainfall. These weather conditions create a major challenge for centralized domestic hot water supply, as conventional heating equipment often suffers from reduced heating capacity and unstable water temperatures. To ensure a reliable and energy-efficient hot water supply for thousands of students, Guizhou Medical University selected AIROSD commercial hot water heat pumps as the core equipment for its campus hot water project.
The project demonstrates how advanced Air source heat pumps can maintain excellent heating performance even in environments characterized by low temperatures and high humidity.
Commercial Hot Water Heat Pumps Designed for Large Campus Applications
The Guizhou Medical University project consists of two independent energy stations equipped with AIROSD commercial hot water heat pumps specially developed for large-scale BOT campus applications. These high-capacity hot water heat pumps are designed to provide continuous domestic hot water for university dormitories while minimizing operating costs.
Unlike traditional boilers or electric water heaters that experience significant efficiency loss during cold and wet weather, AIROSD commercial hot water heat pumps utilize advanced Enhanced Vapor Injection (EVI) technology. This technology significantly improves heating capacity and compressor performance under low ambient temperatures, ensuring a stable hot water supply throughout the winter season.
Field operation shows that the outlet water temperature remains consistently stable regardless of outdoor weather fluctuations. Students enjoy comfortable hot water whenever they need it, even during peak demand periods.
Intelligent Heat Pump Systems Improve Efficiency and User Comfort
One of the greatest advantages of AIROSD heat pump systems is the combination of intelligent control and high energy efficiency.
The entire system incorporates AIROSD's proprietary WAR intelligent control technology, which continuously monitors operating conditions and automatically optimizes compressor, fan, and circulation pump performance. Through advanced inverter coordination and intelligent energy management, these heat pump systems achieve excellent operational stability while reducing unnecessary energy consumption.
The system also supports intelligent scheduled water recirculation and temperature-controlled return water functions, allowing users to enjoy instant hot water without waiting. Meanwhile, the multi-point intelligent defrost control minimizes heat loss during winter operation, ensuring continuous heating performance even under humid weather conditions.
Compared with conventional electric water heaters, AIROSD hot water heat pumps can reduce energy consumption by up to 79%, significantly lowering annual operating costs for educational institutions.
Ultra-Low Temperature Heat Pumps Deliver Reliable Heating at -35°C
Another key advantage of this project is AIROSD's industry-leading ultra-low temperature heat pumps technology.
These ultra-low temperature heat pumps feature newly designed high-efficiency heat exchanger fins together with enhanced inner-grooved copper tubes that maximize heat transfer while reducing overall energy consumption. The optimized refrigeration cycle enables the units to maintain strong heating performance even when outdoor temperatures fall to -35°C.
Unlike conventional heating equipment that struggles during freezing nights or prolonged rainy periods, AIROSD ultra-low temperature heat pumps continue operating with outstanding reliability regardless of seasonal weather changes. This advanced technology ensures uninterrupted hot water production throughout the year, making it particularly suitable for regions experiencing severe winter climates.
Proven Heat Pump Systems Across More Than 100 Educational Institutions
The success of the Guizhou Medical University project is supported by years of practical engineering experience.
AIROSD heat pump systems have already been successfully installed in more than 100 schools across China, providing reliable domestic hot water for over two million students. From humid southern provinces to extremely cold northern regions, AIROSD has accumulated extensive experience in campus hot water engineering.
One representative project is Xuzhou Medical University, where more than 30 AIROSD commercial hot water heat pumps were installed in 2016 to provide daily hot water for over 10,000 students. After years of continuous operation, the system continues to perform efficiently and reliably, demonstrating the long-term durability of AIROSD Air source heat pumps.
Similar projects at Shandong University and many other higher education institutions further validate the outstanding performance of AIROSD hot water heat pumps under a wide range of climatic conditions.
