Abstract: The presented paper focuses on different control strategies of a solar assisted ground source heat pump (SAGSHP) for cold climate. Dynamic simulation approach has been used through TRNSYS software. In particular, a SAGSHP solution operating with the strategies suitable for cold climate found in literature, a conventional ground source heat pump (GSHP) solution and a GSHP with solar thermal system only for building heating supply have been compared to the SAGSHP proposed system. The impact of the considered system solutions on seasonal performance factor and primary energy ratio in case of a gas boiler as auxiliary system has been evaluated as a function of the boreholes depth, the conventional solar thermal collector typologies and the size of the solar thermal system.
