Thermally driven heat pump development and testing

By CNR – ITAE

Within GEOFIT project, a novel heat pump will be developed, able to efficiently exploit geothermal energy to provide heat under several climates and conditions. To this aim, a hybrid configuration for a reversible heat pump is being developed: it consists in the coupling of a gas-driven adsorption cycle with a vapour compression cycle. In this way, the temperature lift on the vapour compression cycle that is commonly employed is reduced and the energy consumption of the component is lower. The proposed solution, that is modular and based on commercial components, is suitable for both new installations and retrofitting applications, allowing a high flexibility.

The heat pump will be developed by FAHRENHEIT GmbH and tested in the laboratories of CNR ITAE.

To this aim, a testing rig suitable for thermal and hybrid chillers/heat pump will be employed.

It is capable of providing constant powers and temperatures to the components of the heat pump, thus allowing to replicate the behaviour under realistic conditions. Sensors installed include temperature sensors, flow meters and energy meters. In the framework of GEOFIT project, the testing activity will be focused on defining a complete performance map of the heat pump and testing different control strategies.

Finally, here are some images of the recently carried out first survey to plan the installation of the hybrid heat pump at the demonstration site of Sant’Apollinare (Perugia).

Geofit Presentation Video

Here is the first video of Geofit, a video that presents the project and launches, with its premiere, the Geofit video series, which will include interviews, updates on demo sites, and will last until the end of the project.

This video presentation of motion graphics explains the context from which the European project Geofit arises: the environmental problem and the barriers and difficulties it faces, as well as the effective and integral solutions provided by the project to overcome them. It also describes the characteristics of our geothermal retrofitting systems and our innovative tools, methods and technologies.

Finally, the video presents the pilot sites where the Geofit systems will be installed to demonstrate the results and all the countries that make up our consortium.

The video is uploaded to Geofit’s YouTube channel, so that everyone can share and help us spread the word about it!

Remember that very soon our first newsletter will be published, with more news.

New public deliverable: “Geothermal – IDM for Drilling Processes”

GEOTHERMAL IDM FOR DRILLING PROCESS

(DRILLING WORKS – MODELLING AND VIRTUALIZATION – GEOTHERMAL BIM INTEGRATION VISUALIZATION, MONITORING AND LIFE CYCLE CONTROL)

Deliverable by IDP

GEOFIT project creates the perfect interaction environment bringing together a set of different disciplines, technologies, knowledge and innovation. One of the main achievements of the project is to create a seven-dimension BIM model covering different aspects like design, planning, programming, installation and deployment, monitoring, simulating, and life cycle and costs management of a building geothermal retrofitting project.

Meet the pilots: Aran Islands

BY AVRIL NÍ SHEARCAIGH

The Aran Islands pilot site in this project is located on Árainn, the largest of the three Aran Islands on the west coast of Ireland. This pilot’s focus is based on residential buildings. The Killeaney Cottages, pictured below, were selected and invited to participate. Eight of the households here are interested in taking part in GEOFIT and having their current heating system replaced by a Geothermal heat pump.

GEOFIT WORKSHOPS: Galway & Aran Islands

At the end of January we held two workshops in Ireland linked to two of our pilot sites, one located in Galway and the other in the Aran Islands. These pilot sites have different characteristics and represent different challenges for the demonstration of our project. In this post we will talk about the development of the workshops, as well as these two pilot sites, so that they can be better known.
