Summary

In order to reach a global reduction in the CO2 emissions, it is key to improve the energy efficiency of systems for producing heating and cooling in buildings. This can be achieved by increasing the use of renewable energies, for instance ground source heat pumps (GSHP). However, special attention should be paid to its optimal design and operation. In this context, the development of dynamic models is a key factor, being the model of the ground source heat exchanger and its coupling to the heat pump particularly important. This coupling needs to be well reproduced both in the short term and long term operation, given that most of the GSHP systems have an on/off operation. In this context, the novel B2G dynamic model was developed and experimentally validated previously for a single U-loop BHE. This work presents the adaptation and experimental validation of the B2G model both to a standard coaxial configuration and to a novel coaxial spiral configuration.
