Preliminary cost and business analysis for different types of building, climates and underground conditions
|
|
|
The report presents the activities related to the Task 1.4 – Preliminary cost and business analysis for different levels of renovation in different types of building, climates and undergrounds – aiming to define the investment gap between conventional solution (condensing boilers, direct exchange chillers) and actual geothermal solutions. A preliminary data base of investment costs at European level has also been performed, taking into account national costs to each project (material, installation and performance).

Definition of key performance indicators to monitor the project progress and objectives
|
|
|
The document contains the key performance indicators that will drive the development and innovation in drilling/heat exchangers, heat pumps and design/control optimization including RES. In addition, these indicators will be the yardstick to evaluate the project results.

|
Development of a compact, rotation-vibration drilling head for urban areas
|
|
|
The document reports the collaboration between Thyssen Krupp Infrastructures (TKI), HYDRA S.R.L. and RED S.R.L. in order to develop an innovative rotating and vibrating head for the installation of ground source heat exchangers. This compact and powerful drilling head needs to fit on a versatile and compact machine for more efficient drilling in built environment. The drilling rig can be utilized in areas with space and/or access restrictions such as historical buildings, low rooms, cellars, underground parking garages, etc. where usually any drilling is hard to realize.
|
|
Development of a versatile, compact drilling machine to operate in urban areas
|
|
|
The drilling machine and equipment were conceived to tackle and overcome the problems and the barriers analyzed in previous tasks.
Several industrial partners from the GEO4CIVHIC consortium have jointly developed a unitary piece of equipment consisting of a compact vibro-rotating drilling head mounted on a novel versatile and compact drilling rig, the whole low weight and small size piece of equipment being able to reach difficult accessible areas such as: inside buildings (low height rooms, cellars, underground parking garages, etc.), inner courtyards or gardens. Furthermore, the required flow of the flushing media (such as water or air) is low, avoiding flooding and contaminating sites that are undesired especially when drilling in susceptible environments, such as inside historical buildings.

Simulation and design of co-axial heat exchangers with regard to performance and costs
|
|
|
This deliverable includes the simulations and evaluations carried out in order to improve the costs and reliability of different solutions for coaxial heat exchangers. Two different innovative solutions of coaxial heat exchangers were analyzed in this task and are presented as the Co-axial Metallic Heat exchanger (CMHE) and the Co-axial Plastic Heat Exchanger (CPHE).

|
Definition of best grouting mix and process for developed geothermal heat exchangers
|
|
|
This document describes all the activities performed in order to characterize some of the most recent and commercially available grouting. This includes also results from studies and research-conducted in past/running projects (i.e. ITER, ThermoMap and in particular Cheap-GSHP and GEOCOND) with high conductivity and eventual integration of Phase Change Material (PCM) mixtures.

Adapted well point technique and subsequent field evaluation for the installation
|
|
|
For construction sites where deep well dewatering is not suitable, the well point dewatering system is an effective and economical way to reduce the level of the water table to below the required excavation level. The well point system is constituted by a series of tubes inserted into the ground at a distance of about 6-8m, all around the excavation area. Usually, after their utilisation, the well point systems are removed from the ground and the equipment can be exploited for new installations. The basic idea developed in this task is to exploit the well point systems by maintaining and adapting the equipment in order to develop shallow coaxial heat exchangers linked to a ground source heat pump as a closed loop system.

Mapping of GSHP for cooling and for low and high temperature terminals for heating
|
|
|
The document presents a market analysis of the most suitable Heat Pump configurations for the retrofit of buildings. Common applications (heating, cooling, Domestic Hot Water, etc.) are considered with their corresponding refrigerant cycles and operating conditions. Possible control strategies are defined. Selection rules to facilitate technology recommendation are drafted, and costs of the different Heat Pump configurations are estimated.

Plug and play solution for small size reversible heat pump in deep retrofit of building
|
|
|
The document presents a preliminary short analysis of refrigerant with low environment impact and the analysis of essential components for geothermal heat pump system. So, the mechanical and electrical designing of the plug and play heat pump. In conclusion it presents the manufactured of N°3 prototypes.

BEMS for GSHP Control and its integration with multiple renewable sources: Specifications and Reference Architecture
|
|
|
The objective of the BEMS is to satisfy the maximum of the building heating and cooling load using renewable sources and to inform the end user about his energy consumption. The BEMS will enable the coupling of a GSHP with two categories of renewables energies: 1) electricity generation and storage technologies such as wind energy, PV systems with electrical storage; 2) auxiliary thermal generation and storage systems such as solar thermal collectors with storage tanks (including PCM), source air-ground HP. It will also support a combination of both scenarios with the possibility to couple a hybrid PV-thermal solution to the GSHP.

|
Recommendations for the planning and implementation of new GSHP systems in dense urban environments and related tool
|
|
|
The objective recommendations is to resolve or prevent possible thermal interferences between nearby geothermal plants, in order to guarantee maximum efficiency for all geothermal systems, even over the long term. Studies and physics confirm that if geothermal plants are near to each other, there are thermal interferences that can have important effects for the good functioning of the system over time.
