FP6-2003-SME-1 Novel Liquid Desiccant Dehumidification System

Start 1 Oct 2005

End 30 Sep 2007

The project aim was to develop and test a low cost, compact and low energy consumption liquid desiccant-based dehumidification system. The advantages of this system were the improvement of air quality and comfort in indoor environments, humidity control and improved capacity of the refrigerant compressor.


FP6-2002-SME-2 Sustainable Heat and Energy Research for Heat Pump Applications

Start 1 Ott 2004

End 31 Dic 2007

This project aimed to develop efficient heat pumps in energy and cost terms, compliant with new environmental regulations through the use of natural refrigerants, such as propane and low-charge heat exchangers.




FP7-ENERGY Advanced ground source heat pump systems for heating and cooling in Mediterranean climate

Start 1 Jan 2009

End 31 Dec 2013

The project involved the development of geothermal heat pumps for heating and cooling, suitable for installation in Southern European countries with a typically Mediterranean climate. Part of the development work involved the optimisation of the “variable speed” concept applied to all the devices on board the heat pumps.




H2020-LCE-2014-2 Geothermal Technology for €conomic Cooling and Heating

Start 01 May 2015

End 30 Apr 2019

The aim of the project was to develop more affordable heat pumps, simpler and faster to install in a plug-and-play system configuration. We also tested the use of low-GWP A2L refrigerants and the development of hybrid source heat pumps.




H2020-LCE-2014-2 Cheap and efficient application of reliable ground source heat exchangers and pumps

Start 1 Jun 2015

End 31 May 2019

The project saw the development of new systems in the field of geothermal energy to reduce capital and running costs of the surface geothermal systems and to improve safety during installation and operation, particularly in historic and listed buildings. This project has facilitated the study and progress of transcritical CO2 technology applied to refrigerants in heat pumps.
