Abstract：
Taking a large-scale ground-source heat pump system of a hospital as the research object, presents the scheme analysis and energy system design, including load forecasting, design of ground heat exchanger, capacity configuration optimization, technical process and automatic control system. Tests the operation data in summer and winter conditions, and analyses the measured results. Performs the dynamic simulation of system operation by software, and compares the simulation results with test results to verify the operation effect. The results show that the ground-source heat pump system has high energy efficiency and achieves the expected design effect. Presents some problems of system operation.
