Recently, the largest ground-source heat pump project in Anhui Province—the East Building Air Conditioning System of the Ground Source Heat Pump Project of the Technical Innovation Public Service and Applied Technology R&D Center of the Self-innovation Comprehensive Test Zone has successfully achieved cold load operation from deep underground. 120 meters of natural air-conditioning is continuously blown out of the tuyere by ground source heat pump equipment. The heating operation cost of the system is 30%-70% lower than that of a traditional central air-conditioning system, and the cooling operation cost is 40%-50% lower, which is efficient, energy-saving, clean, and environmentally friendly.
