| Abstract | Ground Source Heat Pumps are starting to be used in Portugal. College of Engineering and Technology (ESTSetubal) from Polytechnic Institute of Setubal has participated in an European Project - GROUNDHIT project- as demonstration site for Ground Source Heat Pumps (GSHP) - 2 x 15 KWheating; 2 x 12 KWcooling - with a high energetic efficiency. The main goal was to monitoring the prototype of improved energy efficiency (COP = higher than 5,5) in real conditions and test two different Boreholes Heat Exchangers (BHE) types, double-U pipes and coaxial pipes, to acclimatize 7 office rooms and 2 class rooms, in Portuguese climate. Boreholes had good performance during the preliminary monitoring tests, as well as the integrated systems, which show that the GSHP running under real conditions can reach values of COP between 5,5 - 6,0 in heating mode. This demo site can test GSHP’s under real conditions for a southern European region and has an important role for GSHP performance evaluation in Portugal. |
