BTES FOR HEATING AND COOLING OF THE ASTRONOMY HOUSE IN LUND

摘要

Borehole Thermal Energy Storage (BTES) system is used for heating and cooling of the new Institution for Astronomy at the University of Lund in Sweden. The system has been in operation since autumn 2001. 20 boreholes each with a depth of 200 m are placed under the parking area. The system delivers free cooling of 150 MWh with a approximate COP of 50 in summer. The building is heated by the heat pump using the storage as a source of heat and providing 300 MWh of heat.
