Air Source Heat Pump Heating System for Taiyuan Beichen Bilingual School, Shanxi

1. Project Overview
Located in the cold northern zone of China, Taiyuan Beichen Bilingual School has a total heating area of 80,000 ㎡, with local winter extreme low temperature reaching -35℃. To phase out high-pollution, high-consumption coal-fired heating, the school completed a full-campus green heating upgrade with Tongyi ultra-low-temperature air source heat pumps. As a benchmark clean heating project for educational buildings in North China, it has obtained national energy-saving and industry innovation honors.
2. Key Challenges
The project faced typical cold-region application difficulties: stable unit operation at -35℃ extreme low temperature; matched segmented heating for classrooms, dormitories and office areas; compliance with strict campus noise and environmental standards; and long-term efficient and cost-effective operation.
3. Optimized Solution
Tongyi configured 41×60HP and 6×30HP EVI ultra-low-temperature heat pump units with a combined centralized and distributed heat source layout. The system supports independent zonal temperature control and time-shared operation, with automatic load adjustment based on real-time ambient temperature. Equipped with a cloud intelligent management system for remote monitoring and fault pre-warning, it adopts professional vibration and noise reduction structures to fully meet campus environmental requirements.
4. Operational Performance
The system keeps indoor temperature steadily at 18-26℃ throughout winter with uniform and comfortable heating. It cuts annual operating costs by over 2 million RMB with high energy efficiency. Adopting zero-combustion operation, it achieves zero pollutant emissions and low-carbon operation. Featuring a simple structure and low failure rate, it eliminates traditional heating risks and lowers maintenance costs.
5. Project Significance
This project fully validates the stability and practicability of ultra-low-temperature heat pump technology in severe cold climates. Its intelligent zonal heating mode offers a replicable green energy solution for large public buildings in high-latitude cold regions, providing reliable practical references for clean heating promotion in European cold areas.
