Ground Source Heat Pumps (GHSP) utilize the earth’s shallow depths for storing and extracting heat during different seasons in the year. The installation and efficient operation of those geothermal energy systems requires an accurate prediction of their thermal performance. Numerical models are able to simulate the thermal performance accurately but lack the desired computational speed. In this study, a fast and simple analytical method is proposed for evaluating the performance of an injection-extraction well system. The proposed method is benchmarked against a more sophisticated numerical model and observed to be yielding results with a close match.
