PROJECT 3:
GSHP - Calculation of the Borehole Heat Exchanger Total Length

Ground source heat exchangers, also known as geothermal heat pumps, are a highly efficient and environmentally friendly way to heat and cool buildings. They work by transferring heat between the ground and the building, providing a consistent source of energy that can save money on heating and cooling costs as well as decreasing CO2 emissions. The COP of a ground source heat pump is much better than that of an air source heat pump because the temperature of the ground does not change as rapidly and sharply as the outdoor environment throughout the year. In this project, an algorithm was developed for calculating the overall borehole heat exchanger length as a function of building design heat load and thermal properties of the ground. Lastly, the borehole heat exchanger field response after 10 years can be evaluated. You can also use default values as guidance.
