Based on the empirical model and sample data,a simulation model of the condensation heat recov-ery ground source heat pump system was established and developed on the TRNSYS platform.Taking Shang-hai City buildings in hot summer and cold winter areas as an example,the development model was used to study the long-term operation of the condensation heat recovery ground source heat pump system.Benefit.Simulation results show that compared with the traditional ground source heat pump+gas boiler system,the condensation heat recovery ground source heat pump system can keep the soil temperature stable during me-dium and long term operation,reduce the soil temperature rise by 76％,and reduce the energy standard coal consumption once every 20 years of operation.10％,the dynamic investment payback period for condensation heat recovery transformation is 4 years,which has better stable operation and environmental protection and energy saving benefits.
