Application of single factor sensitivity analysis method to design for ground heat exchanger of ground-source heat pump

Analyses the common design factors influencing the running effect of ground heat exchanger system, and introduces the single factor sensitivity analysis method to control the design risk, in order to improve the accuracy and reliability of design work. Taking a ground-source heat pump project as an example, presents the application of this method. Through the single factor sensitivity analysis on the main design parameters of the ground heat exchanger system, discusses the influences of the uncertain factors on average inlet and outlet water temperature, pointing out the direction to control the design risk.
