This module presents a detailed overview of the GEOCOND project. The presentation describes the main objectives and goals that originated the research project, the creation of a robust consortium for covering the main research topics and the presentation of results and achievements that were obtained during the project. The idea of this module is to summarize in general terms the importance of the different actions that will be lately explained in other learning modules.
The objective of this module is to explain the reasons for grouting a borehole heat exchanger (BHE). This practice was introduced gradually after the first BHE in Europe had been installed in the 1980s, and is done in most European countries today, depending on the prevalent geology of the region.
The objective of this subtopic is to introduce Phase Change Materials (PCM) with the focus on organic PCM, to explain what they are and how do they work allowing storage of thermal energy in the form of latent heat. The participants should understand why it is important to impart shape stability to organic PCM, how can it be done and how was it done actually within GEOCOND project framework.
The participants are supposed to understand the importance of proper mixing of the grout and how the grout quality is controlled. This module will refer to the module 3.1 ‘Role of Grouts and its importance in SGES’ where the requirements to grouts and the important properties and parameters are introduced.
The participants are supposed to understand why and in which way the grout is thermally enhanced. This module is based on the previous module 3.3 (RISE) where the basic composition of (standard) grouts for SGES are introduced.
The participants will learn:
What are the modifications to provide the grout with a higher thermal conductivity
What has been developed in GEOCOND to provide the grout with a higher energy storage capacity
The participants will specifically learn how the required fluidity of the grout is adjusted with modern concrete admixtures.
The contents of the module are the following: First, an introduction about the use of plastic pipes in Shallow Geothermal Energy Systems. Then, the description of the pipes extrusion process. The requirements for the design development of plastic pipes for Sallow Geothermal Energy Systems, and to finalize, the GEOCOND's prototypes produced in the framework of GEOCOND project, a pilot and large scales.
This module section presents the process for thermally enhanced pipes production, named as pipe extrusion process, as well as the requirements of the previously developed plastic materials (thermally enhanced polyethylene compounds) from both the processing and the final application points of view. This means requirements about rheological, mechanical and thermal performance.
Large-scale field tests (Borås/Valencia) (Borja Badenes (UPV), Jose M. Cuevas (UPV), Burkhard Sanner (UBeG), Ali Nejad Ghafar (RISE)) [download the pdf document of this presentation by clicking on the title]
In this module, the thermal tests carried out within the framework of the GEOCOND project are outlined.
The Valencia test site is located at the Universitat Politècnica de València (UPV). This is a geothermal laboratory of the highest technological excellence.
This module shows its building process and its main functions.
This video will show the main function of the geothermal laboratory of the Valencia testsite, which is to carry out very precise thermal tests to evaluate the performance of new geothermal heat exchangers.
This module aims: to analyse the improvement in GSHP and BHE performance achievable from using the GEOCOND products; to explain the thermodynamic performance assessment of the BHE as well as the Exergy analysis of a GSHP system for a typical residential house.
