Abstract

A hybrid numerical/analytical one-dimensional model is proposed to predict the thermal behavior of borehole heat exchangers in the short period following a step change in operating conditions. Transient heat transfer in the borehole is solved numerically using an equivalent composite cylinder geometry while ground heat transfer is evaluated analytically using the infinite cylindrical heat source solution. The proposed model is then used to generate
