Résumé

During the past few years, Ground Source Heat Pump (GSHP) systems have attracted great attention because of the ability to improve the efficiency compared to air source heat pumps (AHSP), especially in cold climates. This paper aims to evaluate the performance of a GSHP system with series-connected solar PVT collectors for a Multi Family House (MFH) in the heating-dominated region of Oslo, Norway. The system efficiency has been obtained by a detailed simulation of the system model for 50 years using TRNSYS software. The results indicate that using the PVT collectors can significantly influence the Seasonal Performance Factor (SPF) of the system by maintaining the ground temperature compared to the case without PVT. In addition, a parametric study has been carried out to investigate how much the number of the boreholes can be reduced by adding PVT to the system while maintaining the same SPF as a standard GSHP. Hybrid systems combining GSHP and PVT collectors have the potential to contribute to the decarbonization of the MFHs in dense urban areas and to achieve Zero Energy Buildings (ZEB) in Europe.
