Abstract: The exploitation of Shallow Geothermal Energy (SGE), mainly using Borehole Heat Exchangers (BHE) down to 100 – 200 m depth, has become popular for heating and cooling purposes. The widespread application of BHE to exploit SGE can help European countries to fulfill their commitment in terms of energy saving, renewable energy quota and carbon dioxide emissions reduction. Nonetheless, the current state of the uptake of the technology in the EU varies across Member States, and significant barriers that limit the investments still exist. The potential increase of the use of SGE systems can be related to: 1) moderate the investment costs (drilling, grouting, tubing, pipes), 2) reduce the complexity and safety issues (drilling depth, site-working conditions) and 3) enhance the quota of SGE recovery. All the above points are tackled by the GEOTeCH H2020 European Project, whose overall objective is to promote the very shallow geothermal sector (Download Extended Abstract

Abstract: The use of models that simulate the behaviour of a facility are widely spread as an aid in the design and optimization of heating and cooling systems. In a ground source heat pump system, the most important component is the ground source heat exchanger, but it is also the most complex to model. There are several ground source heat exchanger models, most of them are focused either on the short term or on the long term behaviour. However, the models that are able to predict both the short and the long term need long times of simulation. In this work, a new ground source heat exchanger dynamic model (B2G) is presented, based on an existing ground source heat exchanger located at Universitat Politecnica de Valencia. This model is able to predict the short term response of the heat exchanger with good accuracy and low computational cost. In order to model the long term behaviour, two existing models are considered: the DST model (an already existing model in TRNSYS) and the g-function model. Therefore, the B2G model is coupled with each one of the long term models to consider both the short term and the long term behaviour. The simulation of the ground source heat exchanger operation using the B2G coupled with each of the long term models is compared with the experimental results. The results show that the B2G model is able to reproduce with high accuracy the real behaviour of the ground source heat exchanger when it is coupled with the g-function model as well as with the DST model. In conclusion, this model has a good adaptability to dierent long term models. Download Abstract
