Operation strategy optimization of ground source heat pump system based on monitoring data

Taking a medium sized ground source heat pump project in Shanghai as an example, develops a three dimensional unsteady state heat transfer model and verifies the model by monitoring data. Calculates the ground temperature and average fluid temperature of  buried pipes after five years operation based on the heat transfer model. Discusses the effect of different operation strategies on the ground temperature and the average fluid temperature, and presents an optimal scheme for long-term operation of the system.
