Thermal Storage Coupled to a Ground Source Heat Pump in a Public Services Building

Abstract

Thermal storage may be a particularly attractive approach in service sector buildings, particularly for space conditioning, since it can help to reduce the electricity costs taking advantage of variable electricity rates while helping the grid to overcome the intermittent output of renewable energy. The aim of this paper is to describe globally the thermal storage system, which will be coupled to the ground source heat pump (GSHP), which was installed in a public building in Coimbra within the European Project from FP7 – Ground-Med. This project aims to demonstrate a high seasonal performance factor for ground source heat pumps (GSHP) that will be installed in pilot buildings in southern Europe.
