Abstract
This project focuses on using shallow geothermal energy to provide clean and optimal energy to a 2000 square foot house test site in Dodge City, Kansas. The described test site aims to maintain a consistent temperature of 70°F year-round, 24 hours per day, using the most efficient methods of geothermal energy for the local environment. The identified solution involves a vertical loop with an open-source pumping system from the local aquifer connected to a heat pump. The results demonstrate that cooling can be effectively managed with circulating water from a shallow aquifer, while heating to 70°F requires supplemental energy due to the aquifer's temperature of 60°F. The mechanical and heat transfer process design can be adapted to provide efficient heating and cooling to multiple houses, facilitating an expansion from individual residential use to neighborhood access by connecting houses with horizontal loops. The analysis techniques used in this study can be extrapolated to any location, considering that each location will have different temperature profiles and aquifer depths to extract heat and cooling mediums.
