Abstract

Recently, the ground source heat pump (GSHP) system is actively used because it has high performance of system comparing with other conventional systems. However, the systemic performance can decrease due to excessive and prolonged operation periods. This problem can be solved by combining with other heat source systems. In this research, a hybrid system with GSHP and PVT (Photovoltaic-Thermal) system was proposed and the analysis of system performance was conducted. The analysis model was made by TRNSTS17 and annual performance was calculated based on hourly system performance and weather data. In this paper, in order to decide suitable system capacity between GSHP and PVT, case studies was conducted according to the capacity change of individual system. The simulation was carried out considering various building conditions and local conditions. In the results, a hybrid system can achieve 15.5% higher performance at most than only GSHP system.
